The time has come for us to rise up against this deceptive and powerful industry, to finally kick them out of spaces with influence. It is high time for us to stop being manipulated by fossil fuel companies that are only out to make a profit and harm us.
Temperatures have soared globally this summer. And far from simply being uncomfortable, it’s killing people.
This past July 4 was one of the hottest in US history. While Americans gathered to celebrate the country’s 250th birthday, dozens died from extreme heat—and the toll may still rise. In Europe, which has seen its own devastating heatwave, some 3,700 people have died. And the heat has become so extreme in Pakistan that people’s teeth are literally dissolving in their mouths.
This is only the beginning of extreme heat this summer—and if we don’t stop the climate crisis, for the rest of time. Scientists are warning that this marks “uncharted territory” in rising temperatures.
The good news? We know the solution. To build a better world, with cheaper and cleaner energy, we have to phase out fossil fuels and transition to green energy. This process is easier and cheaper than ever. Some 90% of renewable energy is now cheaper than fossil fuels, and renewables don’t heat our planet the way that fossil fuels do.
As temperatures rise, we are now in a battle of people vs. fossil fuels.
The bad news? Fossil fuel companies, and the politicians who support them, are trying to block this transition. Companies like Exxon have known for over 50 years that fossil fuels cause climate change —and that rising temperatures would cost lives. But they’ve tried to bury this information, stall the transition, and deceive the public that fossil fuels aren’t responsible.
I’ve seen this play out firsthand.
When I was 17, I spent a sunny week in Dubai at the 28th United Nations annual climate conference (COP28). I was so excited to attend the conference. I met other activists passionate about renewable energy and taking down the fossil fuel industry. I even attended lobbying meetings with the lead US negotiators, Trigg Talley and Sue Biniaz.
Everything in Dubai felt larger than life—from the Burj Khalifa to the massive dome in the middle of the conference center. But over the week, the conference began to feel more and more dystopian. The fossil fuel industry had sent 2,456 lobbyists to that COP—and despite the loud cries of activists and scientists, their voices drowned ours out.
At the end of the conference, we had a small win—fossil fuels were mentioned in a COP text for the first time ever. But the language was so weak that the statement felt almost meaningless. The text did nothing to change the trajectory of the climate crisis.
The fossil fuel industry has propagated lies about climate change for years. They’ve tried to convince us that climate change is our fault instead of theirs, with campaigns around “carbon footprints”—a concept created by BP—and recycling, which was popularized by the plastics industry but has never managed to efficiently recycle plastics themselves.
They have also spent hundreds of millions of dollars on influencing climate decision-making spaces—from United Nations conferences to Washington, DC. Big Oil spent $445 million during the 2024 elections—and in return has gotten $40 billion in fossil fuel subsidies from the Trump administration.
The time has come for us to rise up against this deceptive and powerful industry, to finally kick them out of spaces with influence. It is high time for us to stop being manipulated by fossil fuel companies that are only out to make a profit and harm us.
As temperatures rise, we are now in a battle of people vs. fossil fuels. We must win—it’s a matter of life and death.
Blazes mobilized hundreds of firefighters over the weekend and scorched a total of 42,000 acres in Spain, France, and Portugal alone—an area two times the size of Manhattan.
On the heels of a deadly European heatwave, fierce fires erupted in Greece, Spain, Portugal, and France over the weekend, raising fears for a summer of extremes as the effects of the climate emergency become ever more apparent.
The blazes mobilized hundreds of firefighters and scorched a total of 42,000 acres as of Sunday in Spain, France, and Portugal alone—an area two times the size of Manhattan.
" Climate change is here, we are living the consequences and it is only the start of July," French fire service Colonel Eric Belgioino told the public, as Agence France-Presse reported.

One of the fires raging in the South of France forced organizers of the Tour de France to close the third stage of the race to the public on Monday, as Reuters reported.
The fire has consumed 6.18 square miles in Southern France and put two people in critical condition.
"An exceptional fire calls for exceptional measures for the tour," race director Christian Prudhomme said, according to Reuters.
As of Sunday, seven departments in France faced "very high risk” for fires, as temperatures were expected to reach highs of 100-104°F across the south, as Anadolu Agency reported.

Across the border in Spain, a fire in Costa Brava burned through over 5,400 acres in a 48-hour period, according to AFP. The flames led to shelter-in-place or evacuation orders for nearly 50,000 people.
The Catalunya fire service said on Sunday that firefighters "worked tirelessly throughout the night to consolidate the perimeter of the La Bisbal d'Empordà forest fire, which is now stabilized."

In Greece, two fires erupted on Saturday and Sunday.
The first, in the Oraiokastro suburb of the country's second-largest city of Thessaloniki, compelled evacuations and shelter-in-place orders when it overtook a recycling plant and released dangerous smoke into the air, The Associated Press reported.
“The smoke contains volatile organic compounds that irritate the eyes and throat, as well as carcinogenic substances such as benzene, dioxins, and furans,” Dimosthenis Sarigiannis, professor of environmental engineering at the Aristotle University of Thessaloniki, told ekathimerini.com.
The inferno also damaged multiple homes and businesses, Oraiokastro Mayor Pandelis Tsakiris told the country's state broadcaster.
The second blaze ignited on Sunday west of Athens, according to AP, and 210 firefighters worked hard to control it before the sun set and firefighting planes would be grounded.
The European fires follow a heatwave that scientists said would have been "virtually impossible" without climate change caused by the burning of fossil fuels, and spark concerns that the continent could see a devastating summer for fires.
French Interior Minister Laurent Nunez noted that the fire season had started one month early, according to AFP.
As fire Colonel Belgioino said: "The season is going to be long for the soldiers fighting fires. You have to help us."
"How we confront the climate crisis will determine a lot about the next 250 years of American history, including if we make it that long," one climate advocate said. "The revolution we need today is the clean energy revolution."
The US reliance on and promotion of fossil fuels is interfering with its ability to celebrate its 250th birthday, as several July 4 events were canceled due to a dangerous, record-breaking heatwave in the Central and Eastern US that scientists say would have been "virtually impossible" without the climate emergency.
As millions of people sweltered under heat alerts, extreme heat and humidity led to the cancellation of both Washington, DC and Philadelphia's Independence Day parades. Nearly 30 other events in states including Alabama, Delaware, New Jersey, New York, Pennsylvania, Maryland, and Virginia were modified, postponed, or canceled, according to USA Today.

"The US having to cancel major 4th of July celebrations because of extreme heat is almost too spot on as a metaphor for the country’s failure to combat global warming," Fossil Free Media director Jamie Henn told Common Dreams. "How we confront the climate crisis will determine a lot about the next 250 years of American history, including if we make it that long. The revolution we need today is the clean energy revolution so we can finally declare our independence from fossil fuels."
Happy Independence Day!🇺🇸🎆

Temperature records were tied or broken in 22 locations on Thursday and 17 on Friday, according to CNN, with DC breaking a 120-year record on both days with temperatures above 102°F.
The heat forced the temporary closure Friday afternoon of the Great American State Fair on the National Mall, and seven attendees required "advanced life support," probably due to heat exposure, according to CNN.
Matt Rein, the Democratic National Committee's influencer and creative partnerships director, reported from the state fair on Saturday that local emergency workers said guests were "dropping like flies" due to the heat.

Meanwhile, one group who tried to draw attention to the climate emergency at a July 4 event was evicted for its efforts by the US Coast Guard, as the Times Union reported. The nonprofit Hudson River Sloop Clearwater had attempted to join Saturday's Sail4th 250 parade of tall ships to New York Harbor when its sailboat was removed by the guard. The Coast Guard later said it was due to banners the boat was displaying reading, "Save the Clean Water Act” and “Indigenous rights, racial justice, climate solutions,” despite the fact that the group had the event organizer's permission to participate.

The heat dome that has settled over the Central and Eastern US over the July 4 weekend is so dangerous in part because it includes high humidity along with high heat, with heat indexes of 105-115°F expected in some places. This corresponds with a Wet Bulb Global Temperature (WBGT)—a measurement that accounts for heat, humidity, and air flow—of 28-30°C, at which point it is dangerous for even healthy people to be physically active outdoors. According to World Weather Attribution, the current heatwave broke regional records for WBGT.
"It is still a relatively rare event even in today’s climate, that has warmed by 1.4°C due to the burning of fossil fuels. In a 1.4°C cooler climate, WBGTs as high as those forecast in early July 2026 would have been so extreme as to be virtually impossible," the group wrote on Friday.
Friederike Otto, a professor of climate science at Imperial College London, told CNN, “When a historic 4th of July celebration is disrupted, and World Cup matches are played in conditions that are unsafe for players and fans, it shouldn’t take another scientific study to wake people up."
Otto continued, "Climate change is here, it’s already impacting the things we enjoy in our everyday lives, and it will continue to get worse the longer we drag out the inevitable transition to net zero emissions.”
Climate scientist and communicator Katharine Hayhoe encouraged people to use this opportunity to talk about the climate emergency to their friends and family:
Heatwaves aren't new. But I'm a climate scientist, and I can tell you heatwaves like this are virtually impossible without fossil fuel pollution. Not only that, but when extreme weather hits, research shows that connecting it to climate change helps people understand why it matters. And you know who the most trusted people to do that are? Not scientists. You! Yes, people we know are the most effective messengers to have these conversations. So if you're worried about what's happening and how extreme heat puts us at risk—talk about it!
While the US is the world's leading historical emitter of greenhouse gas emissions, and its military is the No. 1 institutional climate polluter, the Trump administration in particular has taken steps to accelerate the climate emergency by increasing oil, gas, and coal production while hindering the development of renewable energy.
"Trump’s promotion of coal burning and cancellation of wind turbines make him the Benedict Arnold of America’s current struggle, not its George Washington."
Just two days before the nation's birthday, Energy Secretary and fracking CEO Chris Wright bragged on social media that the Trump administration would end subsidies for new wind and solar on July 4.
Climate scientist Rebekah Jones shot back: "During a record heatwave, no less. Fossil fuel industries have received $549 BILLION in direct subsidies, and $7 TRILLION in tax benefits. They average $30 billion per year in upfront taxpayer money. All of renewable energy recieved $400 million per year from 1994-2009."
Tennessee state Sen. Heidi Campbell (D-20) also called out the move: "Talk about 'slugs for salt’—it's 119 degree heat index in the Eastern US this week—these guys are all in on the rapture."
In a July 4 post, scholar Juan Cole argued that President Donald Trump's climate policies were tantamount to treason.
"Since 2018, some 13,000 Americans have died from heat," he said. "Trump’s promotion of coal burning and cancellation of wind turbines make him the Benedict Arnold of America’s current struggle, not its George Washington."
Cole pointed out that the current heatwave was part of a pattern of hotter summers in the nation's capital due to the climate emergency, noting that the last decade was its hottest on record.
He continued:
The bad news is that this is only the beginning. Summers in the capital are going to be more dangerous every decade unless we halt dangerous carbon emissions.
The average summer temperature in DC could be 97°F in the 2080s if we go on farting out CO2 at our current rate. Humidity will also increase, as the Atlantic heats up and puts more water vapor in the atmosphere. The ability of the atmosphere to hold water vapor increases 7% with every 1°C increase in temperature.
That combined with more frequent storms and sea-level rise opens up the possiblity that DC "will be unlivable in the summers within the lifetime of my younger readers," he wrote.
"Trump is helping climate change accomplish what British military might could not, putting in question the future of America in places like Washington, DC and Baltimore, at least in the summers," Cole said.
One journalist called it "the kind of thing somebody can genuinely be prosecuted for if someone dies, which is not uncommon if you slap it together like this."
In what some described as a "fitting metaphor" for the state of the US, a large panel fell from the stage at President Donald Trump's 250th anniversary extravaganza, nearly crushing a group of young dancers during a rehearsal.
A video of the falling piece of debris was posted to social media Thursday by the independent journalist Aaron Parnas, who wrote, "The stage is falling apart at the rehearsal for Freedom 250's July 4th celebration."
The giant panel interrupted a patriotic dance number, making a loud crash and sending bits of dust and shrapnel flying just feet behind the troupe of what appeared to be about two-dozen performers on the event's Salute to America stage, where many of the festival's biggest acts are taking place.
“We’re grateful to report that everyone is safe,” a Freedom 250 representative said. “We take the safety of our performers, crew, volunteers, and guests extremely seriously.”
He added that "additional safeguards and senior technical oversight are now in place as preparations continue.”
HuffPost deputy editor Philip Lewis said it was "literally a miracle no one was hurt."
From a scourge of algae in the reflecting pool, to the rash of headline acts bailing from their performances, to the persistent low attendance, and empty booths, the festivities—commandeered by the Trump-aligned Freedom 250 operation—has been seemingly marred by one indignity after another.
Power outages have led the supply of ice cream to become liquefied by the heat, and a faulty generator has led the giant Ferris wheel to run only intermittently.
A model of the president's planned "Arc de Trump" has been mocked as "a sad, peeling mess" by Margaret Hartmann of New York Magazine, who noted the creasing vinyl, cracking wood, and caulk oozing out the sides. The mid-festival addition of a series of improvised columns did little to stop it from being referred to as a "Temu arch."
Other buildings were haphazardly overlaid with vinyl covers designed to look like three-dimensional pieces of classical architecture.
An interim report published Thursday by Democrats on the House Natural Resources Committee emphasized the festival's dual role—in addition to being a monument to Trump's ego—as yet another opportunity for his donors and allies to profit.
Through the newly created Freedom 250 group, the report alleges, Trump has used the event to sell sponsorship packages promising VIP access, speaking roles, private receptions, and photo opportunities with the president.
It also points to federal contracts for Trump-connected event vendors, official merchandise sales through a Trump campaign vendor, and event-registration data routed through a firm founded by former Trump digital strategist Brad Parscale.
The company in charge of the State Fair's production is Event Strategies, Inc.—a firm run by a group of longtime Trump aides. According to the San Francisco Chronicle, it has received taxpayer funds through the National Park Foundation, though it remains unclear how much the company has made.
It's also unclear what, if any, oversights may have led to the dangerous stage mishap. However, the use of an opaque private charity to fund the festival appears to have enabled corner-cutting elsewhere.
According to the Democratic report, the UFC arena on the White House South Lawn “bypassed layers of [National Park Service]-mandated environmental review,” allowing the commercial fighting organization headed by Trump pal Dana White to save time and money, which led to a lawsuit last month seeking to stop the event.
Journalist Ryan Grim said that if there have indeed been safety rules flouted, the falling panel is "the kind of thing somebody can genuinely be prosecuted for if someone dies, which is not uncommon if you slap it together like this."
Many found the short video deeply resonant—a microcosm of the unprecedented elite enrichment that has taken place during the second Trump administration, subsidized by bone-deep cuts to social safety net programs that have made life more precarious for millions of people, including many children.
Political commentator J Aubrey said that it was "hard to imagine a more fitting metaphor for our rapidly decaying society."
There is, unnervingly, still plenty of time for a deadly incident to occur at the fair.
The president's Independence Day celebration is slated to culminate in the launching of 850,000 firework shells from near the reflecting pool and several other sites along the Potomac River.
The National Park Service has projected the display would cause “very unhealthy” conditions around central DC, including particulate pollution that can harm those with asthma, according to documents uncovered by The Washington Post.
Soaring temperatures have also put Washington under severe drought, turning the surrounding area into a potential tinderbox. DC Water has said it was coordinating with federal officials in the case that a forest fire breaks out.
"It only takes one small spark landing in dry vegetation under the right conditions to start a fast-moving wildfire," April Newman, a public information officer at Cal Fire, told Axios.
Trump himself, who recently turned 80 years old and is rumored to be in poor health, is also not immune to the dangers.
The president declared that on Independence Day, "when it's going to be approximately 107 degrees out... I'm going to make a really long speech."
That speech, scheduled for 9:45 pm ET, will take place on the Salute to America stage.
As power grids become strained amid the latest US heatwave, residents of communities with data centers are being asked to make sacrifices in the form of cost, comfort, and potentially safety.
The rise of global temperatures has made oppressive summer heatwaves an annual occurrence, and for many Americans, air conditioning is no longer optional.
But as scorching temperatures bear down on the US once again this week, affecting more than 250 million people across the country, some are suddenly being forced to share the precious cool air with data centers that have popped up in their towns to power the breakneck build-out of artificial intelligence technology.
To keep their massive arrays of computer servers cool, these complexes require large amounts of energy even in normal times. But during a heatwave, the demand becomes even greater.
As power grids become strained, residents of communities with data centers are being asked to make sacrifices in the form of cost, comfort, and potentially safety.
In Henrico County, Virginia, which has 37 data centers, thousands of county employees received an email last week from County Manager John Vithoulkas warning them that beginning on July 1, the rate paid by "government and school facilities will increase dramatically—by 25%, increasing costs by an estimated $5 million next fiscal year."
"To mitigate the impact of higher electric costs, I am asking that we, collectively, make slight adjustments to conserve electricity across our individual workspaces,” he said in the email, which was obtained by 404 Media. “Turn off your lights when leaving your workspace, including when you leave for the day,” he continued. “Turn off your computers/laptops at the end of each workday. If your workspace has windows, adjust the blinds to manage heat from sunlight.”
He also informed them of the high cost of running "space heaters," which Frank Landymore of Futurism.com suggested was a thinly veiled way of telling residents to turn down the AC, since nobody would be using space heaters in 100-degree heat.
It was a signifier of what's happened across the entire mid-Atlantic grid, whose largest operator, PJM Interconnection, is experiencing record energy demand.
According to Reuters, the grid that supplies power to 67 million people has seen a roughly 1,000% increase in capacity prices since 2024 as a result of the AI boom, which is already being passed onto consumers in the form of higher bills.
To reduce the risk of outages caused by an overburdened grid, the US Department of Energy granted PJM the authority to require data centers to operate backup diesel generators.
Under the emergency order, Politico reported, data centers are allowed to produce enough diesel emissions that the Environmental Protection Agency (EPA) would categorize it as a "possible human carcinogen."
The result has been what Shaolei Ren, a professor at the University of California, Riverside, told The Associated Press could be “a disaster for the local air quality" in communities with data centers.
In Lowell, Massachusetts, where a Markley Group data center sits in the working-class Sacred Heart neighborhood, residents told the AP that they were staying inside to avoid smelling the diesel fumes being belched up near their homes.
Public backlash led the Lowell City Council to vote unanimously for a moratorium on data center building in February. But many residents feel the damage has already been done, with the Markley center gobbling up their town's electric and water resources.
One resident told The Harvard Crimson in May that since the center came to town, his winter electric bill has shot up from $40 to $177.
As temperatures spiked this week, more than 200 protesters flooded a local zoning meeting to voice their anger about the noise, pollution, and surveillance equipment bearing down on their homes. One 14-year-old girl was dragged out of the meeting by police officers.
"I'm not hurting anyone," she shouted as cops escorted her through the exit. "We just don't want data centers!"
Within roughly three years, data centers have come to consume about 4.5% of all electricity in the US, a number that is expected to keep ballooning in the coming years.
Even before the data center boom began, scientists had long warned that the climate crisis caused by human carbon emissions would make US heatwaves more frequent, longer, and more intense.
Heatwaves in major US cities are already three times as common as they were in the 1960s, according to an EPA report from 2024, and the average heatwave season is now 46 days longer.
The number of heat-related deaths in the US more than doubled from 1,069 in 1999 to 2,325 in 2023, according to a JAMA Network study analyzing mortality data from the Centers for Disease Control and Prevention.
With more than 1,500 data center projects currently underway across the US, a vicious cycle appears poised to accelerate.
The rapid buildout of data centers has already culminated in massive emission spikes. Amazon, which once pledged to reach net-zero emissions by 2040, saw its carbon output increase by 16% in 2025 in large part due to its multi-billion dollar data center buildout.
According to a report out Wednesday from the Environmental Integrity Project, at least 74 natural gas-fired power plants are being planned to power the industry's expansion, which are expected to release 662 million tons of greenhouse gas—equivalent to the entire nation of Australia—per year.
Many of the plants are being built in low-income areas that already have poorer health outcomes and could produce nearly 160,000 tons of health-damaging pollutants that can cause lung damage, asthma, and heart attacks.
“In their wholehearted embrace of dirty and outdated gas power, data center developers are announcing to the public that they don’t care about us," said Alex Bomstein, the executive director at Clean Air Council. "We deserve better than decades of toxic pollution, parched streambeds, and climate chaos.”
"As remarkable as this might appear, it is not really surprising as the continuous warming of the climate system inevitably leads to new temperature extremes," said the head of the E.U. climate service.
Last month was the warmest February on record, the European Union’s climate service said Wednesday, marking the ninth consecutive month of unprecedented heat as the climate crisis continues to drive up global temperatures.
Climate scientists say the climate crisis, without a doubt, is to blame for increased temperatures.
Not only was it warm above sea level—global ocean temperatures also reached a record high last month. That's not just for February but for any month on record.
"Ocean warming has prompted concerns about the mass bleaching of coral reefs. It also raises global sea levels and can help to fuel higher intensity hurricanes," the BBC reports. "Unusually warm waters may also have been a factor in another exceptional month for Antarctic sea ice. The three lowest minimum extents in the satellite era have now occurred in the last three years."

Arctic sea ice is also disappearing, and the Arctic could be virtually ice-free during the summer within a decade.
"February joins the long streak of records of the last few months," said Carlo Buentempo, director of the Copernicus Climate Change Service. "As remarkable as this might appear, it is not really surprising as the continuous warming of the climate system inevitably leads to new temperature extremes."
“The climate responds to the actual concentrations of greenhouse gases in the atmosphere so, unless we manage to stabilize those, we will inevitably face new global temperature records and their consequences,” Buentempo added.
The last year has been over 1.5°C above pre-industrial averages—1.56°C, to be exact—but that won't signify a breach of the goals set in the Paris Agreement unless temperatures remain elevated for the next few years.
"A year ago, the fact that the global temperature for a particular month would reach 1.5°C above the pre-industrial level would have been considered exceptional," Julien Nicolas, a senior scientist at Copernicus, told The New York Times.
The world will have to get off of fossil fuels in order to halt runaway warming, and this year could help determine the future of the climate, considering one of the people running to lead the nation appears destined to unleash billions of tons of additional planet-warming emissions should he return to office.
"Breaking heat records has become the norm in 2023," said one scientist. "Global warming continues because we have not stopped burning fossil fuels. It is that simple."
Climate scientists across the world have been alarmed over the past three months by fast-spreading wildfires, prolonged and deadly heatwaves, and numerous shattered heat records across the northern hemisphere both in the oceans and on land—and data released Tuesday confirmed that the past three months have been the hottest summer on record, driven by humans' continued emission of heat-trapping gases and compounded by El Niño.
The Copernicus Climate Change Service (C3S), the European Union's climate agency, found that the global average temperature during June, July, and August reached 16.77°C (62.18°F), which was 0.66°C or 1.18°F above the 1991-2020 average.
The previous temperature record was set in 2019 and was 0.29°C (0.5°F) lower than this year's high.
Last month was the hottest August on record "by a large margin," said the World Meteorological Organization, with the average temperature 1.5°C higher than the preindustrial average.
United Nations Secretary-General António Guterres said Wednesday the world is experiencing the consequences of "our fossil fuel addiction," which "scientists have long warned" would be unleashed if humans continue extracting oil and gas instead of rapidly shifting to renewable energy sources.
"Our planet has just endured a season of simmering—the hottest summer on record. Climate breakdown has begun," said Guterres.
"In the southern hemisphere Antarctic sea ice extent was literally off the charts, and the global sea surface temperature was once again at a new record. It is worth noting that this is happening BEFORE we see the full warming impact of the El Niño event."
C3S released the data as the Eastern United States experienced a "dangerous heatwave," with cities including New York and Washington, D.C. announcing heat advisories.
As the World Weather Attribution (WWA) said earlier this summer, the extreme heat felt across North America and Europe in July—the hottest month ever on record, followed by August—would have been "virtually impossible" without planetary heating and the climate crisis.
Scientists at the WWA also found that the hot, dry conditions that allowed wildfires to spread rapidly in Eastern Canada were made twice as likely by the climate emergency, and independent scientists at Climate Central determined that the current heat forecast in the United Kingdom—with temperatures over 33°C or 91°F expected in London on Saturday—was made five times more likely.
Friederike Otto, a senior lecturer on climate change and the environment at Imperial College London, told The Guardian that "breaking heat records has become the norm in 2023."
" Global warming continues because we have not stopped burning fossil fuels," said Otto. "It is that simple."
Scientists last observed a powerful El Niño warming event, which is marked by very high temperatures in the Pacific Ocean near the equator, in 2016, which currently holds the record for the hottest January-August period, followed by this year.
El Niño is still developing this year, and experts have warned that next summer could see even more intense heatwaves and wildfires as the effects of the warming phenomenon are typically observed the year after it develops.
"The northern hemisphere just had a summer of extremes—with repeated heatwaves fueling devastating wildfires, harming health, disrupting daily lives, and wreaking a lasting toll on the environment," said Petteri Taalas, secretary-general of the WMO. "In the southern hemisphere Antarctic sea ice extent was literally off the charts, and the global sea surface temperature was once again at a new record. It is worth noting that this is happening BEFORE we see the full warming impact of the El Niño event."
Mark Maslin, professor of earth system science at University College London, told The Guardian that the news from C3S "is a wake-up call to international leaders that we must rapidly reduce carbon emissions now."
"Let us hope this message hits home at COP28... this December and action actually happens," Maslin said.
Advocates have raised alarm about the appointment of Sultan Ahmed Al Jaber, CEO of the United Arab Emirates' Abu Dhabi National Oil Company, to lead the United Nations Climate Change Conference, also known as COP28, later this year.
"Surging temperatures demand a surge in action," said Guterres. "Leaders must turn up the heat now for climate solutions. We can still avoid the worst of climate chaos—and we don't have a moment to lose."
"I have no doubt a dip in Manatee Bay today would have been a hot tub-like experience," said one meteorologist earlier this week.
A buoy positioned roughly 40 miles south of Miami recorded a sea surface temperature of 101.1°F earlier this week, stunning scientists who say the reading could mark the latest in a string of global records as fossil fuel-driven extreme weather around the world brings unprecedented heat.
Meteorologist Jeff Masters wrote that the temperature in Florida's Manatee Bay reached hot tub levels on Monday and "could be a world record."
"I have no doubt a dip in Manatee Bay today would have been a hot tub-like experience, with [sea surface temperatures] near 100°F, and that these waters were some of the hottest ever recorded on Earth," Masters added. "A detailed investigation would be needed to determine if this was a world record SST, though."
A 2020 study suggested that the highest sea surface temperature ever recorded was 99.7°F in Kuwait Bay.
The Manatee Bay reading was "among several extreme values in South Florida's offshore waters," The Washington Post reported Tuesday.
"To the southwest, a buoy near Johnson Key topped out at 98.4 degrees. The temperature hovered at or above 98 degrees for several hours during the evening," the Post noted. "A majority of buoys in the area reached or surpassed 95 degrees during the day. In fact, the average of the two dozen observation locations in and around Florida Bay was right around 96 degrees during the early evening."
Last year was the hottest on record for Earth's oceans, and 2023 is shaping up to be the fifth consecutive year in which global ocean temperatures reach new highs. According to the Copernicus Climate Change Service (C3S), "Global average sea surface temperatures last month reached unprecedented levels for June."
"The North Atlantic Ocean recorded exceptionally warm sea surface temperatures, with several extreme marine heatwaves," C3S added. "These were related to short-term changes in atmospheric circulation and longer-term changes in the ocean."
The National Oceanic and Atmospheric Administration (NOAA) observed earlier this month that it has "tracked a steady climb in ocean temperatures since April 2023, which is causing unprecedented heat stress conditions in the Caribbean Basin, including waters surrounding Florida and in the Gulf of Mexico." Oceans absorb 90% of excess heat associated with planetary heating, according to NOAA.
"Developing tropical storms that pass into the region may strengthen as a result of these conditions," NOAA stressed. "The ongoing marine heat wave in South Florida could impact sensitive marine ecosystems in the region, such as shallow water corals."
The Coral Restoration Foundation said this past weekend that it found "100% coral mortality" at Sombrero Reef, a restoration site in the Florida Keys.
"Climate change is our present reality," said R. Scott Winters, the foundation's CEO. "The impact on our reefs is undeniable. This crisis must serve as a wake-up call, emphasizing the need for globally concerted efforts to combat climate change."
As parts of Alaska obliterated high-temperature records earlier this week, meteorologists and climate scientists warned that extreme heat and rainfall are the new normal in the nation's largest state and other Arctic and subarctic zones.
"In and around the Arctic... temperatures have been rising around twice as fast as the rest of the planet."
On Sunday, the town of Kodiak in southern Alaska hit 67degF--seven degrees warmer than the daytime high in San Diego--and shattering the December record for Alaska by nine degrees, according to the National Weather Service. The town also broke the local December record by more than 20 degrees.
"I would not have thought such a thing possible," Rick Thoman, a climate specialist at the Alaska Center for Climate Assessment and Policy, tweeted Tuesday.
CNN meteorologist Brandon Miller said that "we've become somewhat numb to these 'never before seen' extremes in temperature and weather as climate change continues to push the envelope on what is possible all over the globe."
"In and around the Arctic this is especially true, where temperatures have been rising around twice as fast as the rest of the planet," he added.
Warmer air is wetter air, as higher temperatures mean the atmosphere can store more water vapor. Miller said this explains why more intense rainstorms and flooding are increasing along with global temperatures.
"Each degree Fahrenheit of warming can hold about 4% more water vapor," he said, "and much of Alaska was 40 degrees Fahrenheit or above average temperatures for late December."
Parts of Alaska have suffered record rainfall this month. CNN reports Fairbanks has been inundated with 4.75" of liquid-equivalent precipitation for the month--more than 10 times the historical average.
A study published last month in Nature Communications noted that "as the Arctic continues to warm faster than the rest of the planet, evidence mounts that the region is experiencing unprecedented environmental change," with "the hydrological cycle... projected to intensify throughout the 21st century [and] increased evaporation from expanding open water areas and more precipitation."
The paper projected that Arctic winters will experience more rain than snow beginning sometime in the 2060s.
Extreme temperatures aren't just occurring during the Alaskan winters. In July 2019, Anchorage recorded an all-time high of 90degF. In July 2021, the record-breaking heatwave during which Lytton, British Columbia, set a Canadian record of 121degF triggered a 2.7-magnitude cryoseism, or "ice quake," near Juneau, Alaska's capital, as 92-degree heat melted glacier ice that subsequently saturated into the soil and then rapidly refroze.
Wildfires--which accelerate global heating by releasing massive amounts of carbon dioxide into the atmosphere--are also increasing along with Alaska's rising temperatures.
Scientists also warn that thawing Arctic permafrost in the northern parts of the state constitutes a "geological time bomb" set to release potentially devastating quantities of methane--a super-potent greenhouse gas whose emissions are roughly 87 times more potent than carbon dioxide emissions over a 20-year period--into the atmosphere.
As the Pacific Northwest and southwestern Canada bake under what's described as a "once-in-a-millennium" heat dome, green groups reiterated the need for transformational change to address the climate emergency on Monday. Progressive U.S. lawmakers underscored the imperative for any infrastructure legislation to center climate action.
" Extreme heat in Portland is literally melting our critical infrastructure. It's yet another striking example of why our infrastructure package must center climate action."
--Rep. Earl Blumenauer
On Monday, temperatures exceeded 110 degrees in Portland, Oregon, for the second straight day—and the third consecutive record-setting day—melting power cables, destroying road surfaces, and shaking some homes.
On Monday, the mercury in Seattle soared to a record-setting 106 degrees, with some surrounding areas expected to reach as high as 115 degrees.
On Sunday, the town of Lytton, British Columbia, broke Canada's all-time high-temperature record, becoming the first place in the country to reach 45 degrees Celsius (113 degrees Fahrenheit).
As groups including 350 Seattle and Defense Fund PDX mobilized to distribute potentially lifesaving hydration and cooling aid in their communities, they also issued urgent calls for immediate climate action.
Valerie Costa of 350 Seattle said that the historic heatwave "is terrifying proof that we have to transform business as usual immediately, to stop the damage that we can still stop. Lives all over the world depend on it."
350 Seattle's Emily Johnston added, "People can get air conditioners and then try to forget how wildly abnormal this is... or they can join us in fighting for the immediate transformation that we need."
"Other cities around the world have transformed even in just the last few years, dramatically increasing bike lanes, otherwise shifting land use, and rejecting airport expansion," Johnston added. "Seattle has mostly... made pronouncements. We mean to harness people's energy and anxiety to change that."
Meanwhile, Sunrise Movement PDX called out "legislators in Oregon who claim to be 'acting on climate' who voted yesterday to give the [state] authority to spend hundreds of millions of dollars widening freeways in Clackamas County."
Progressive lawmakers echoed some of climate campaigners' calls and concerns.
Noting Portland's melting power cables, Rep. Earl Blumenauer (D-Ore.) called the heatwave "yet another striking example of why our infrastructure package must center climate action to halt, reverse, mitigate, and prepare for the worst consequences of the climate crisis."
Blumenauer, Rep. Alexandria Ocasio-Cortez (D-N.Y.), and Sen. Bernie Sanders (I-Vt.) in February introduced a bill directing President Joe Biden to declare a national climate emergency and mobilize every resource available to address the crisis.
In a tweet highlighting a Monday rally and march on the White House by the youth-led Sunrise Movement, Rep. Ilhan Omar (D-Minn.) asserted that "making sure our planet is habitable for human life is infrastructure" while calling for "a bold package that tackles the climate crisis."
In addition to much of the western part of the continent, much of New England also experienced extreme temperatures on Monday, with heat advisories in effect across the region.
Amid triple-digit heat indexes in Massachusetts, Sen. Ed Markey (D-Mass.) announced he would re-introduce the Preventing Health Emergencies And Temperature-related (HEAT) Illness and Deaths Act "to combat the threat of extreme heat" and "strengthen inter-agency efforts to study and address extreme heat while providing millions of dollars in grants to reduce exposure to extreme heat."
