Human Influence on Climate Clear, IPCC Report Says
STOCKHOLM
Human influence on the climate system is clear. This is evident in most regions of the globe, a new assessment by the Intergovernmental Panel on Climate Change (IPCC) concludes.
It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century. The evidence for this has grown, thanks to more and better observations, an improved understanding of the climate system response and improved climate models.
Warming in the climate system is unequivocal and since 1950 many changes have been observed throughout the climate system that are unprecedented over decades to millennia. Each of the last three decades has been successively warmer at the Earth's surface than any preceding decade since 1850, reports the Summary for Policymakers of the IPCC Working Group I assessment report, Climate Change 2013: the Physical Science Basis, approved on Friday by member governments of the IPCC in Stockholm, Sweden.
"Observations of changes in the climate system are based on multiple lines of independent evidence. Our assessment of the science finds that the atmosphere and ocean have warmed, the amount of snow and ice has diminished, the global mean sea level has risen and the concentrations of greenhouse gases have increased," said Qin Dahe, Co-Chair of IPCC Working Group I.
Thomas Stocker, the other Co-Chair of Working Group I said: "Continued emissions of greenhouse gases will cause further warming and changes in all components of the climate system. Limiting climate change will require substantial and sustained reductions of greenhouse gas emissions."
"Global surface temperature change for the end of the 21st century is projected to be likely to exceed 1.5degC relative to 1850 to 1900 in all but the lowest scenario considered, and likely to exceed 2degC for the two high scenarios," said Co-Chair Thomas Stocker. "Heat waves are very likely to occur more frequently and last longer. As the Earth warms, we expect to see currently wet regions receiving more rainfall, and dry regions receiving less, although there will be exceptions," he added.
Projections of climate change are based on a new set of four scenarios of future greenhouse gas concentrations and aerosols, spanning a wide range of possible futures. The Working Group I report assessed global and regional-scale climate change for the early, mid-, and later 21st century.
"As the ocean warms, and glaciers and ice sheets reduce, global mean sea level will continue to rise, but at a faster rate than we have experienced over the past 40 years," said Co-Chair Qin Dahe. The report finds with high confidence that ocean warming dominates the increase in energy stored in the climate system, accounting for more than 90% of the energy accumulated between 1971 and 2010.
Co-Chair Thomas Stocker concluded: "As a result of our past, present and expected future emissions of CO2, we are committed to climate change, and effects will persist for many centuries even if emissions of CO2 stop."
Rajendra Pachauri, Chair of the IPCC, said: "This Working Group I Summary for Policymakers provides important insights into the scientific basis of climate change. It provides a firm foundation for considerations of the impacts of climate change on human and natural systems and ways to meet the challenge of climate change." These are among the aspects assessed in the contributions of Working Group II and Working Group III to be released in March and April 2014. The IPCC Fifth Assessment Report cycle concludes with the publication of its Synthesis Report in October 2014.
"I would like to thank the Co-Chairs of Working Group I and the hundreds of scientists and experts who served as authors and review editors for producing a comprehensive and scientifically robust summary. I also express my thanks to the more than one thousand expert reviewers worldwide for contributing their expertise in preparation of this assessment," said IPCC Chair Pachauri.

Background
Working Group I is co-chaired by Qin Dahe of the China Meteorological Administration, Beijing, China, and Thomas Stocker of the University of Bern, Switzerland. The Technical Support Unit of Working Group I is hosted by the University of Bern and funded by the Government of Switzerland.
At the 28th Session of the IPCC held in April 2008, the members of the IPCC decided to prepare a Fifth Assessment Report (AR5). A Scoping Meeting was convened in July 2009 to develop the scope and outline of the AR5. The resulting outlines for the three Working Group contributions to the AR5 were approved at the 31st Session of the IPCC in October 2009.
The Summary for Policymakers of the IPCC WGI AR5 was approved at the Twelfth Session of IPCC Working Group I meeting in Stockholm, Sweden, 23 to 26 September 2013 and was released on 27 September.
The Final Draft of the Working Group I report (version distributed to governments on 7 June 2013), including the Technical Summary, 14 chapters and an Atlas of Global and Regional Climate Projections, will be released online in unedited form on Monday 30 September. Following copy- editing, layout, final checks for errors, and adjustments for changes in the Summary for Policymakers, the full report of Working Group I will be published online in January 2014 and in book form by Cambridge University Press a few months later.
The Working Group I assessment comprises some 2,500 pages of text and draws on millions of observations and over 2 million gigabytes of numerical data from climate model simulations. Over 9,200 scientific publications are cited, more than three quarters of which have been published since the last IPCC assessment in 2007.
In this IPCC assessment report, specific terms are used to indicate the assessed likelihood of an outcome or a result. For those terms used above: virtually certain means 99-100% probability, extremely likely: 95-100%, very likely: 90-100%, likely: 66-100%. For more information see the

The Intergovernmental Panel on Climate Change is an intergovernmental body of the United Nations. Its job is to advance scientific knowledge about climate change caused by human activities. The World Meteorological Organization and the United Nations Environment Programme established the IPCC in 1988.

50,000 March in Brazil to Celebrate Death of Fossil Fuel Industry at COP30
"It is time to put these old fuels where they belong—in the ground of history.”
Nov 16, 2025
An estimated 50,000 people took to the streets of Belém do Pará, Brazil on Saturday to demonstrate outside the halls of the United Nations annual climate summit, holding a "Great People's March" and makeshift "Funeral for Fossil Fuels" as they demanded a just transition toward a more renewable energy system and egalitarian economy.
Organized by civil society organizations and Indigenous Peoples groups from Brazil and beyond, the tens of thousands who marched outside the thirtieth Conference of the Parties (COP30) summit called for an end to the rapacious greed of the oil, gas, and coal companies as they advocated for big polluters to pay for the large-scale damage their businesses have caused worldwide over the last century.
“We are tens of thousands here today, on the streets of Belém, to show negotiators at COP30 that this is what people power looks like," said Carolina Pasquali, executive director of Greenpeace Brazil, said as the march took hold. "Yesterday we found out that one in every 25 COP30 participants is a fossil fuel lobbyist, proportionally a 12% increase from last year’s COP. How can the climate crisis be solved while those creating it are influencing the talks and delaying decisions? The people are getting fed up–enough talking, we need action and we need it now.”
The report by the Kick Big Polluters Out coalition last week showed that at least 1,600 lobbyists from the fossil fuel industry are present at the conference, making it the second-largest delegation overall, second only to Brazil's, the host nation.
"It’s common sense that you cannot solve a problem by giving power to those who caused it," said Jax Bongon from the Philippines-based IBON International, a member of the coalition, in a Friday statement. "Yet three decades and 30 COPs later, more than 1,500 fossil fuel lobbyists are roaming the climate talks as if they belong here. It is infuriating to watch their influence deepen year after year, making a mockery of the process and of the communities suffering its consequences."
While the overwhelming presence of fossil fuel lobbyists has once again diminished hopes that anything worthwhile will emerge from the conference, the tens of thousands in the streets on Saturday represented the ongoing determination of the global climate movement.
João Talocchi, co-founder of Alianza Potência Energética Latin America, one of the key groups behind the "Funeral for Fossil Fuels" portion of the day's action—which included mock caskets for the oil, gas, and coal companies alongside parades of jungle animals, wind turbines, and solar panels representing what's at stake and the better path forward—noted the key leadership of Indigenous groups from across the Global South.
"From the Global South to the world, we are showing what a fair and courageous energy transition must look like," said Talochhi.
Ilan Zugman, director of 350.org in Latin America and the Caribbean, noted the significance of the demonstration, including the symbolism of the funeral procession.
"We march symbolically burying fossil fuels because they are the root of the crisis threatening our lives," explained Zugman. "Humanity already knows the way forward: clean energy, climate justice, and respect for the peoples who protect life. What is missing is political courage to break once and for all with oil, gas, and coal. It is time to put these old fuels where they belong—in the ground of history.”
With the COP30 at its midway point, climate activists warn that not nearly enough progress is being made, with the outsized influence of the fossil fuel industry one of the key reasons that governments, year after year and decade after decade, continue to drag their feet when it comes to taking the kind of aggressive actions to stem the climate crisis that scientists and experts say is necessary.
“We are taking to the streets because, while governments are not acting fast enough to make polluters pay for their climate damages at COP30, extreme weather events continue to wreak havoc across the globe," said Abdoulaye Diallo, co-head of Greenpeace International's "Make Polluters Pay" campaign. "That is why we are here, carrying the climate polluters bill, showing the projected economic damages of more than $5 trillion from the emissions of just five oil and gas companies over the last decade."
"Fossil fuel companies are destroying our planet, and people are paying the price," said Diallo. "Negotiators must wake up to the growing public and political pressure to make polluters pay, and agree to new polluter taxes in the final COP30 outcome."

'National Security Threat'? 95-Year-Old Human Rights Scholar Richard Falk Interrogated for Hours by Canada
"Clearly, the international repression of the Palestinian cause knows no bounds."
Nov 15, 2025
Ninety-five-year-old Richard Falk—world renowned scholar of international law and former UN special rapporteur focused on Palestinian rights—was detained and interrogated for several hours along with his wife, legal scholar Hilal Elver, as the pair entered Canada for a conference focused on that nation's complicity with Israel's genocide in Gaza.
"A security person came and said, ‘We’ve detained you both because we’re concerned that you pose a national security threat to Canada,'” Falk explained to Al-Jazeera in a Saturday interview from Ottawa in the wake of the incident that happened at the international airport in Toronto ahead of the scheduled event.
“It was my first experience of this sort–ever–in my life,” said Falk, professor emeritus of international law at Princeton University, author or editor of more than 20 books, and formerly the UN special rapporteur on the situation of human rights in the Palestinian territories.
Falk, who is American, has been an outspoken critic of the foreign policy of Canada, the United States, and other Western nations on the subject of Israel-Palestine as well as other issues. He told media outlets that he and his wife, also an American, were held for over four hours after their arrival in Toronto. They were in the country to speak and participate at the Palestine Tribunal on Canadian Responsibility, an event scheduled for Friday and Saturday in Ottawa, the nation's capital.
The event, according to the program notes on the website, was designed to "document the multiple ways that Canadian entities – including government bodies, corporations, universities, charities, media, and other cultural institutions–have enabled and continue to enable the settler colonization and genocide of Palestinians, and to articulate what justice and reparations would require."
In his comments to Al-Jazeera, Falk said he believes the interrogation by the Canadian authorities—which he described as "nothing particularly aggressive" but "random" and "disorganized" in its execution—is part of a global effort by powerful nations complicit with human rights abuses and violations of international law to “punish those who endeavour to tell the truth about what is happening” in the world, including in Gaza.
Martin Shaw, a British sociologist and author of The New Age of Genocide, said the treatment of Falk and Elver should be seen as an "extraordinary development" for Canada, and not in a good way. For a nation that likes to think of itself as a "supporter of international justice," said Shaw, "to arrest the veteran scholar and former UN rapporteur Richard Falk while he is attending a Gaza tribunal. Clearly, the international repression of the Palestinian cause knows no bounds."
Canadian Senator Yuen Pau Woo, a supporter of the Palestine Tribunal, told Al-Jazeera he was “appalled” by the interrogation.
“We know they were here to attend the Palestine Tribunal. We know they have been outspoken in documenting and publicizing the horrors inflicted on Gaza by Israel, and advocating for justice,” Woo said. “If those are the factums for their detention, then it suggests that the Canadian government considers these acts of seeking justice for Palestine to be national security threats–and I’d like to know why.”

Maine Senate Candidate Graham Platner Says 'Nobody Works Hard Enough to Justify $1 Billion'
"I refuse to believe that in a state like Maine where people work as hard as we do here, that it is merely hard work that gets you that kind of success. We all know it isn't. We all know it's the structures. It's the tax code."
Nov 15, 2025
Echoing recent viral comments by music superstar Billie Eilish, Maine Democratic candidate for US Senate Graham Planter is also arguing that the existence of billionaires cannot be justified in a world where working-class people with multiple jobs still cannot afford the basic necessities of life.
In video clip posted Friday of a campaign event in the northern town of Caribou from last month, Platner rails against the "structures" of an economy in which billionaires with vast personal fortunes use their wealth to bend government—including the tax code—to conform to their interests while working people are left increasingly locked out of controlling their own destinies, both materially and politically.
"Nobody works hard enough to justify $1 billion," the military veteran and oyster farmer told potential voters at the event. "Not in a world where I know people that have three jobs and can't even afford their rent."
With audience members nodding their heads in agreement, Platner continued by saying, "I refuse to believe that in a state like Maine, where people work as hard as we do here, that it is merely hard work that gets you that kind of success. We all know it isn't. We all know it's the structures. It's the tax code. That is what allows that money to get accrued."

The systemic reasons that create vast inequality, Platner continued, are also why he believes that the process of the super wealthy becoming richer and richer at the expense of working people can be reversed.
"The world that we live in today," he explained, "is not organic. It is not natural. The political and economic world we have did not happen because it had to. It happened because politicians in Washington and the billionaires who write the policies that they pushed made this happen. They changed the laws, and they made it legal to accrue as much wealth and power as they have now."
The solution? "We need to make it illegal again to do that," says Platner.
The comments questioning the justification for billionaires to even exist by Platner—though made in early October—echo more recent comments that went viral when spoken by Billie Eilish, a popular musician, who told a roomful of Wall Street movers and shakers in early November that they should do a better job reflecting on their outrageous wealth.
"Love you all, but there’s a few people in here that have a lot more money than me," Eilish said during an award event in New York City. "If you’re a billionaire, why are you a billionaire? No hate, but yeah, give your money away, shorties."
"If you're a billionaire, why are you a billionaire?"

While those remarks took a long spin around the internet, Eilish on Friday doubled down on uncharitable billionaires by colorfully calling Elon Musk, who could end up being the world's first trillionaire, a "fucking pathetic pussy bitch coward" for not donating more of his vast fortune, among the largest in the world, to humanitarian relief efforts.
This week, as Common Dreams reported, a coalition of economists and policy experts called for the creation of a new international body to address the global crisis of inequality.
Like Platner, the group behind the call—including economists like Joseph Stiglitz, Thomas Piketty, Ha-Joon Chang, and Jayati Ghosh—emphasized the inequality-as-a-policy-choice framework. Piketty, who has called for the mass taxation of dynastic wealth as a key part of the solution to runaway inequality, said “we are at a dangerous moment in human history” with “the very essence of democracy” under threat if something is not done.
On the campaign trail in Maine, Platner has repeatedly suggested that only organized people can defeat the power of the oligarchs, which he has named as the chief enemy of working people in his state and beyond. The working class, he said at a separate rally, "have an immense amount of power, but we only have it if we're organized."
