World Scientists Declare Climate Emergency, Establish Global Indicators for Effective Action
A global coalition of scientists led by William J. Ripple and Christopher Wolf of Oregon State University says "untold human suffering" is unavoidable without deep and lasting shifts in human activities that contribute to greenhouse gas emissions and other factors related to climate change.
CORVALLIS, Ore.
A global coalition of scientists led by William J. Ripple and Christopher Wolf of Oregon State University says "untold human suffering" is unavoidable without deep and lasting shifts in human activities that contribute to greenhouse gas emissions and other factors related to climate change.
"Despite 40 years of major global negotiations, we have continued to conduct business as usual and have failed to address this crisis," said Ripple, distinguished professor of ecology in the OSU College of Forestry. "Climate change has arrived and is accelerating faster than many scientists expected."
In a paper published today in BioScience, the authors, along with more than 11,000 scientist signatories from 153 countries, declare a climate emergency, present graphics showing trends as vital signs against which to measure progress, and provide a set of effective mitigating actions.
The scientists point to six areas in which humanity should take immediate steps to slow down the effects of a warming planet:
- Energy. Implement massive conservation practices; replace fossil fuels with low-carbon renewables; leave remaining stocks of fossil fuels in the ground; eliminate subsidies to fossil fuel companies; and impose carbon fees that are high enough to restrain the use of fossil fuels.
- Short-lived pollutants. Swiftly cut emissions of methane, soot, hydrofluorocarbons and other short-lived climate pollutants; doing so has the potential to reduce the short-term warming trend by more than 50% over the next few decades.
- Nature. Restore and protect ecosystems such as forests, grasslands, peatlands, wetlands and mangroves, and allow a larger share of these ecosystems to reach their ecological potential for sequestering atmospheric carbon dioxide, a key greenhouse gas.
- Food. Eat more plants and consume fewer animal products. The dietary shift would significantly reduce emissions of methane and other greenhouse gases and free up agricultural lands for growing human food rather than livestock feed. Reducing food waste is also critical - the scientists say at least one-third of all food produced ends up as garbage.
- Economy. Convert the economy to one that is carbon free to address human dependence on the biosphere and shift goals away from the growth of gross domestic product and the pursuit of affluence. Curb exploitation of ecosystems to maintain long-term biosphere sustainability.
- Population. Stabilize a global human population that is increasing by more than 200,000 people a day, using approaches that ensure social and economic justice.
"Mitigating and adapting to climate change while honoring the diversity of humans entails major transformations in the ways our global society functions and interacts with natural ecosystems," the paper states. "We are encouraged by a recent surge of concern. Governmental bodies are making climate emergency declarations. Schoolchildren are striking. Ecocide lawsuits are proceeding in the courts. Grassroots citizen movements are demanding change, and many countries, states and provinces, cities, and businesses are responding. As an Alliance of World Scientists, we stand ready to assist decision makers in a just transition to a sustainable and equitable future."
The graphs of vital signs in the paper illustrate several key climate-change indicators and factors over the last 40 years, since scientists from 50 nations met at the First World Climate Conference in Geneva in 1979.
In recent decades, multiple other global assemblies have agreed that urgent action is essential, but greenhouse gas emissions are still rapidly rising. Other ominous signs from human activities include sustained increases in per-capita meat production, global tree cover loss and number of airline passengers.
There are also some encouraging signs - including decreases in global birth rates and decelerated forest loss in the Brazilian Amazon, and increases in wind and solar power - but even those measures are tinged with worry. The decline in birth rates has slowed over the last 20 years, for example, and the pace of Amazon forest loss appears to be starting to increase again.
"Global surface temperature, ocean heat content, extreme weather and its costs, sea level, ocean acidity, and area burned in the United States are all rising," Ripple said. "Globally, ice is rapidly disappearing as demonstrated by decreases in minimum summer Arctic sea ice, Greenland and Antarctic ice sheets, and glacier thickness. All of these rapid changes highlight the urgent need for action."
Joining Ripple and Wolf, a postdoctoral scholar in the OSU College of Forestry, as authors are Thomas M. Newsome of the University of Sydney, Phoebe Barnard of the Biological Conservation Institute and the University of Cape Town, and William R. Moomaw of Tufts University.
More information on the project, the list of signatories and the Alliance of World Scientists is available here.
Two years ago, Ripple lead an international team of researchers in producing an article published in BioScience titled "World Scientists' Warning to Humanity: A Second Notice" that was signed by more than 15,000 scientists in 184 countries.
The warning came with steps that can be taken to reverse negative trends, but the authors suggested it may take a groundswell of public pressure to convince political leaders to take corrective actions. Since 1992, when more than 1,700 scientists -- including a majority of the living Nobel laureates in the sciences--signed a "World Scientists' Warning to Humanity" published by the Union of Concerned Scientists, global trends have worsened.

At Least 95 Palestinians Killed in Israeli Attacks Including Massacres at Beach Café, Aid Points
"I saw body parts flying everywhere, and bodies cut and burned," said one eyewitness to a strike on the popular al-Baqa Café.
Jun 30, 2025
Israeli forces ramped up their genocidal assault on the Gaza Strip Monday, killing at least 95 Palestinians in attacks including massacres at a seaside café and a humanitarian aid distribution center and bombings of five school shelters housing displaced families and a hospital where refugees were sheltering in tents.
An Israeli strike targeted the al-Baqa Café in western Gaza City, one of the few operating businesses remaining after 633 days of Israel's obliteration of the coastal strip and a popular gathering place for journalists, university students, artists, and others seeking reliable internet service and a respite from nearly 21 months of near-relentless attacks.
Medical sources said at least 33 civilians were killed and nearly 50 others wounded in the massacre, including footballer Mustafa Abu Amira, photojournalist Ismail Abu Hatab—who survived an earlier Israeli airstrike and is reportedly the 227th journalists killed by Israel since October 2023—and prominent artist Frans Al-Salmi, whose final painting depicting a young Palestinian woman killed by Israeli forces resembles photographs of its slain creator posted on social media after her killing.
Warning: Photos shows image of death
Survivor Ali Abu Ateila toldThe Associated Press that the café was crowded with women and children at the time of the attack.
"Without a warning, all of a sudden, a warplane hit the place, shaking it like an earthquake," he said.
Another survivor of the massacre told Britain's Sky News: "All I see is blood... Unbelievable. People come here to take a break from what they see inside Gaza. They come westward to breathe."
Eyewitness Ahmed Al-Nayrab toldAgence France-Presse that a "huge explosion shook the area."
"I saw body parts flying everywhere, and bodies cut and burned," he said. "It was a scene that made your skin crawl."
Witnesses and officials said Israeli Defense Forces (IDF) troops opened fire on Palestinians seeking food and other humanitarian aid from a U.S.-backed Gaza Humanitarian Foundation distribution point in southern Gaza, killing 15 people amid near-daily massacres of aid-seekers.
"We were targeted by artillery," survivor Monzer Hisham Ismail told The Associated Press. Another survivor, Yousef Mahmoud Mokheimar, told the AP that Israeli troops "fired at us indiscriminately." Mokheimar was shot in the leg, another man who tried to rescue him was also shot.
IDF troops have killed nearly 600 Palestinian aid-seekers and wounded more than 4,000 others over the past month, with Israeli military officers and soldiers saying they were ordered to deliberately fire on civilians in search of food and other necessities amid Israel's weaponized starvation of Gaza.
Another 13 people were reportedly killed Monday when IDF warplanes bombed an aid warehouse in the Zeitoun quarter of southern Gaza City, according to al-Ahli Baptist Hospital officials cited by The Palestine Chronicle. IDF warplanes also reportedly bombed five schools housing displaced families, three of them in Zeitoun. Israeli forces also bombed the courtyard of al-Aqsa Hospital in Deir al-Balah in central Gaza, where thousands of forcibly displaced Palestinian families are sheltering in tents. It was reportedly the 12th time the hospital has been bombed since the start of the war.
The World Health Organization has documented more than 700 attacks on Gaza healthcare facilities since October 2023. Most of Gaza's hospitals are out of service due to Israeli attacks, some of which have been called genocidal by United Nations experts.
Israel's overall behavior in the war is the subject of an ongoing International Court of Justice genocide case, while Israeli Prime Minister Benjamin Netanyahu is wanted by the International Criminal Court for alleged war crimes and crimes against humanity in Gaza, including murder and using starvation as a weapon of war.
Since October 2023, Israeli forces have killed or wounded more than 204,000 Palestinians in Gaza, including over 14,000 people who are missing and presumed dead and buried under rubble, according to the Gaza Health Ministry, whose casualty figures have been found to be generally accurate and even a likely undercount by peer-reviewed studies.
The intensified IDF attacks follow Israel's issuance of new forced evacuation orders amid the ongoing Operation Gideon's Chariots, an ongoing offensive which aims to conquer and indefinitely occupy all of Gaza and ethnically cleanse much of its population, possibly to make way for Jewish recolonization as advocated by many right-wing Israelis.

'We Cannot Be Silent': Tlaib Leads 19 US Lawmakers Demanding Israel Stop Starving Gaza
"This current blockade is starving Palestinian civilians in violation of international law, and the militarization of food will not help."
Jun 30, 2025
As the death toll from Israel's forced starvation of Palestinians continues to rise amid the ongoing U.S.-backed genocidal assault and siege of the Gaza Strip, Rep. Rashida Tlaib on Monday led 18 congressional colleagues in a letter demanding that the Trump administration push for an immediate cease-fire, an end to the Israeli blockade, and a resumption of humanitarian aid into the embattled coastal enclave.
"We are outraged at the weaponization of humanitarian aid and escalating use of starvation as a weapon of war by the Israeli government against the Palestinian people in Gaza," Tlaib (D-Mich.)—the only Palestinian American member of Congress—and the other lawmakers wrote in their letter to U.S. Secretary of State Marco Rubio. "For over three months, Israeli authorities have blocked nearly all humanitarian aid from entering Gaza, fueling mass starvation and suffering among over 2 million people. This follows over 600 days of bombardment, destruction, and forced displacement, and nearly two decades of siege."
"According to experts, 100% of the population is now at risk of famine, and nearly half a million civilians, most of them children, are facing 'catastrophic' conditions of 'starvation, death, destitution, and extremely critical acute malnutrition levels,'" the legislators noted. "These actions are a direct violation of both U.S. and international humanitarian law, with devastating human consequences."
Gaza officials have reported that hundreds of Palestinians—including at least 66 children—have died in Gaza from malnutrition and lack of medicine since Israel ratcheted up its siege in early March. Earlier this month, the United Nations Children's Fund warned that childhood malnutrition was "rising at an alarming rate," with 5,119 children under the age of 5 treated for the life-threatening condition in May alone. Of those treated children, 636 were diagnosed with severe acute malnutrition, the most lethal form of the condition.
Meanwhile, nearly 600 Palestinians have been killed and more than 4,000 others have been injured as Israeli occupation forces carry out near-daily massacres of desperate people seeking food and other humanitarian aid at or near distribution sites run by the U.S.-backed Gaza Humanitarian Foundation (GHF). Israel Defense Forces officers and troops have said that they were ordered to shoot and shell aid-seeking Gazans, even when they posed no threat.
"This is not aid," the lawmakers' letter argues. "UNRWA Commissioner-General Philippe Lazzarini has warned that, under the GHF, 'aid distribution has become a death trap.' We cannot allow this to continue."
"We strongly oppose any efforts to dismantle the existing U.N.-led humanitarian coordination system in Gaza, which is ready to resume operations immediately once the blockade is lifted," the legislators wrote. "Replacing this system with the GHF further restricts lifesaving aid and undermines the work of long-standing, trusted humanitarian organizations. The result of this policy will be continued starvation and famine."
"We cannot be silent. This current blockade is starving Palestinian civilians in violation of international law, and the militarization of food will not help," the lawmakers added. "We demand an immediate end to the blockade, an immediate resumption of unfettered humanitarian aid entry into Gaza, the restoration of U.S. funding to UNRWA, and an immediate and lasting cease-fire. Any other path forward is a path toward greater hunger, famine, and death."
Since launching the retaliatory annihilation of Gaza in response to the Hamas-led October 7, 2023 attack on Israel, Israeli forces have killed at least 56,531 Palestinians and wounded more than 133,600 others, according to the Gaza Health Ministry, which also says over 14,000 people are missing and presumed dead and buried beneath rubble. Upward of 2 million Gazans have been forcibly displaced, often more than once.
On Sunday, U.S. President Donald Trump reiterated a call for a cease-fire deal that would secure the release of the remaining 22 living Israeli and other hostages held by Hamas.
In addition to Tlaib, the letter to Rubio was signed by Sen. Bernie Sanders (I-Vt.) and Democratic Reps. Greg Casar (Texas), Jesús "Chuy" García (Ill.), Al Green (Texas), Jonathan Jackson (Ill.), Pramila Jayapal (Wash.), Henry "Hank"Johnson (Ga.), Summer Lee (Pa.), Jim McGovern (Mass.), Alexandria Ocasio-Cortez (N.Y.), Ilhan Omar (Minn.), Chellie Pingree (Maine), Mark Pocan (Wisc.), Ayanna Pressley (Mass.), Delia Ramirez (Ill.), Paul Tonko (N.Y.), Nydia Velázquez (N.Y.), and Bonnie Watson Coleman (N.J.).

Biden National Security Adviser Among Those Crafting 'Project 2029' Policy Agenda for Democrats
"Jake Sullivan's been a critical decision-maker in every Democratic catastrophe of the last decade," said one observer. "Why is he still in the inner circle?"
Jun 30, 2025
Amid the latest battle over the direction the Democratic Party should move in, a number of strategists and political advisers from across the center-left's ideological spectrum are assembling a committee to determine the policy agenda they hope will be taken up by a Democratic successor to President Donald Trump.
Some of the names on the list of people crafting the agenda—named Project 2029, an echo of the far-right Project 2025 blueprint Trump is currently enacting—left progressives with deepened concerns that party insiders have "learnt nothing" and "forgotten nothing" from the president's electoral victories against centrist Democratic candidates over the past decade, as one economist said.
The project is being assembled by former Democratic speechwriter Andrei Cherny, now co-founder of the policy journal Democracy: A Journal of Ideas, and includes Jake Sullivan, a former national security adviser under the Biden administration; Jim Kessler, founder of the centrist think tank Third Way; and Neera Tanden, president of the Center for American Progress and longtime adviser to former Secretary of State Hillary Clinton.
Progressives on the advisory board for the project include economist Justin Wolfers and former Roosevelt Institute president Felicia Wong, but antitrust expert Hal Singer said any policy agenda aimed at securing a Democratic victory in the 2028 election "needs way more progressives."
As The New York Times noted in its reporting on Project 2029, the panel is being convened amid extensive infighting regarding how the Democratic Party can win back control of the White House and Congress.
After democratic socialist and state Assemblymember Zohran Mamdani's (D-36) surprise win against former New York Gov. Andrew Cuomo last week in New York City's mayoral primary election—following a campaign with a clear-eyed focus on making childcare, rent, public transit, and groceries more affordable—New York City has emerged as a battleground in the fight. Influential Democrats including House Minority Leader Hakeem Jeffries (D-N.Y.) and Sen. Kirsten Gillibrand (D-N.Y.) have so far refused to endorse him and attacked him for his unequivocal support for Palestinian rights.
Progressives have called on party leaders to back Mamdani, pointing to his popularity with young voters, and accept that his clear message about making life more affordable for working families resonated with Democratic constituents.
But speaking to the Times, Democratic pollster Celinda Lake exemplified how many of the party's strategists have insisted that candidates only need to package their messages to voters differently—not change the messages to match the political priorities of Mamdani and other popular progressives like Sen. Bernie Sanders (I-Vt.) and Rep. Alexandria Ocasio-Cortez (D-N.Y.).
"We didn't lack policies," Lake told the Times of recent national elections. "But we lacked a functioning narrative to communicate those policies."
Sanders and Ocasio-Cortez have drawn crowds of thousands in red districts this year at Sanders' Fighting Oligarchy rallies—another sign, progressives say, that voters are responding to politicians who focus on billionaires' outsized control over the U.S. political system and on economic justice.
Project 2029's inclusion of strategists like Kessler, who declared economic populism "a dead end for Democrats" in 2013, demonstrates "the whole problem [with Democratic leadership] in a nutshell," said Jonathan Cohn of Progressive Mass—as does Sullivan's seat on the advisory board.
As national security adviser to President Joe Biden, Sullivan played a key role in the administration's defense and funding of Israel's assault on Gaza, which international experts and human rights groups have said is a genocide.
"Jake Sullivan's been a critical decision-maker in every Democratic catastrophe of the last decade: Hillary Clinton's 2016 campaign, the withdrawal from Afghanistan, the Israel/Gaza War, and the 2024 Joe Biden campaign," said Nick Field of the Pennsylvania Capital-Star. "Why is he still in the inner circle?"
"Jake Sullivan is shaping domestic policy for the next Democratic administration," he added. "Who is happy with the Biden foreign policy legacy?"
