It’s 20 years since we started blogging on climate here on RealClimate (December 10, 2004). We wanted to counter disinformation about climatechange that was spreading through various campaigns. In a nutshell, they are responsible for climatechange, mainly due to an increased greenhouse effect.
Skip to main content Scientific American Opinion July 4, 2025 5 min read A Thought Experiment Reveals the Fingerprints of ClimateChange Came Early Climatechange left its signature on the atmosphere early in the industrial revolution, reveals a thought experiment investigation By Ben Santer , Susan Solomon , David W.
In videos and Congressional testimony , Wright portrays himself as a truth teller, while falsely claiming that climatescientists and renewable energy advocates are deceptive. The Fifth National Climate Assessment is equally clear: Human activities are changing the climate. Leading independent global and U.S.
For almost 2 decades, along with like-minded citizens, we have organized, petitioned, sued, testified, commented, and protested in an effort to get our state government to take a more measured approach to shale gas development coupled with decisive action on climatechange. And this brings us to the matter at hand.
Of course, an honest assessment of the latest climate science will show that since 2009 the evidence has become even more compelling and dire. Climatechange, driven by rising heat-trapping emissions, is already causing significant harm to peoples health and well-being and to vital ecosystems.
Climatechange is our reality these days as we navigate hotter days, more severe storms, wildfires, and other previously-rare weather extremes. We are adapting to climatechange. But our infrastructure isnt. Wait, what!?
Behind these individual instances of harm is a clear strategy: they want to bury the scientific evidence of the impacts and economic damages caused by climatechange to avoid having to take any action to address them. More expensive property and infrastructure exposed to climate-fueled disasters contribute to higher damage costs.
Heres what else has happened in the last 7 days No Climate Assessment: The Trump administration has unceremoniously dismissed all the expert authors of the next authoritative look at how climatechange is affecting the US. Climatechange will lead to municipal bankruptcies. billion aid package.
The news that started leaking last Friday is that the Trump administration wants to break up the National Oceanic and Atmospheric Administration and essentially end NOAAs climate work by abolishing its primary research office and forcing the agency to instead help boost U.S. In fact, the US could be pushing China and the EU closer together.

Climatescientist Michael Mann called the report “a deeply misleading antiscientific narrative, built on deceptive arguments, misrepresented datasets, and distortion of actual scientific understanding.”
This 2009 legal determination is based on extensive scientific evidence that says heat-trapping emissions from activities like the burning of fossil fuels are driving climatechange and posing a threat to human health and welfare. climate,” per the title. global warming emissions.
But he also voices full-throated conspiracy theories denying the reality of human-caused climatechange. These election fraud and anti-vaccine conspiracies converge with some far-out ideas about climate science. is on when it comes to the war on scientists. is on when it comes to the war on scientists.
According to the United Nations’ Intergovernmental Panel on ClimateChange report published Monday, Southeast Asia coastal zones are among the world’s most climate vulnerable regions. Graphic courtesy of the Intergovernmental Panel on ClimateChange. Carl Ganter / Circle of Blue.
All countries in the world urgently need to adapt to climatechange but are not yet in a good position to do so. It’s urgent because we are not even adapted to the present climate. However, I would argue that the climate research community has not had a visible presence during any of these meetings.
Former NASA climatescientist James Hansen urged Congress decades ago to act on climatechange. Now he says he expects reduced aerosol pollution to lead to a steep temperature rise.
I followed with great interest the launch of the sixth assessment report Working Group 1 (The Physical Science Basis) from the Intergovernmental Panel on ClimateChange (IPCC) on August 9th. The cause of our changingclimate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.
A friend asked me if a discussion paper published on Statistics Norway’s website, ‘ To what extent are temperature levels changing due to greenhouse gas emissions? ’, was purposely timed for the next climate summit ( COP28 ). I don’t know the answer to his question. But this discussion paper is problematic for sure.
Three of these are highlighted as priority research areas: attribution science, climatechange and human health, and economic modeling. We also identified five strategic areas for further research at the forefront of climate litigation.
This week, Circle of Blue looks at a major new climate report, which finds that a warming planet is accelerating the water cycle. The Intergovernmental Panel on ClimateChange, a group of the world’s leading climatescientists, has released its sixth assessment report. The report, while grim, does offer hope.
A state court judge in the ‘Last Best Place’ just gave the youth climate movement a shot in the arm with the first decision of its kind that directly connects specific state actions to global climatechange and then to injuries suffered by young people. courts have not yet engaged in this kind of fact-finding on climatechange.
There has been a lot of commentary about perceived disagreements among climatescientists about whether climatechange is, or will soon, accelerate. Li, "Global warming in the pipeline", Oxford Open ClimateChange , vol. As with most punditry, there is less here than it might seem. von Schuckmann, N.G.
As I outlined here , Montana state law prohibits the consideration of greenhouse gas emissions or climate impacts–– inside and outside the state’s borders––when reviewing projects and approving permits. This now-infamous climate prohibition has been called a “limitation” on the Montana Environmental Policy Act, or MEPA.
The state contended that their actions are not responsible for global climatechange. It reminded me of the unsurprising, but still disappointing finger pointing between high carbon emitting-countries while negotiating climate responsibilities and greenhouse gas emission caps at COP27. I felt giddy when I read her words.
This post was co-authored by UCS Principal ClimateScientist Kristina Dahl. Outline of a Special Report on ClimateChange and Cities Delegates dissected the proposed outline for the ClimateChange and Cities report over several days. Ultimately, and to our great relief, science prevailed.
“Optimism and hope are muscles we have to exercise,” climatescientist Rob Jackson says. His new book offers a paradigm for how to think about climatechange and the health of the planet.
As climatescientists we tend to look at the IPCC reports a little differently than the general public might. Here are a few things that mark this report out from previous versions that relate to issues we’ve discussed here before: Extreme events are increasingly connected to climate (duh!) 1, SPM, AR5.
A new paper discusses ‘climate end games’ as the planet approaches environmental tipping points that could exacerbate other global crises like pandemics and war.
The promise from many nations is to reach net-zero greenhouse-gas emissions by 2050 (or earlier) and interim targets are essential. But the United Nations has just said that the latest commitments of the 192 parties of the 2015 Paris agreement will equate to a 16% rise in global greenhouse-gas emissions in 2030 compared to 2010.
“A code red for humanity” is how António Guterres, the United Nations’ secretary general, described the latest report from the Intergovernmental Panel on ClimateChange , which summarizes our current scientific understanding of the Earth’s climate and the potential impact that changes to it could have on the planet.

Yesterday the International Panel on ClimateChange (IPCC) published its latest report and compared our current situation to defusing a time bomb. This should be front news and urge us all to change our lives radically. When I started covering climatechange on this blog in 2007, climatechange was a distant threat.
For climatescientists, the war in Ukraine came at the worst possible time as the media attention they would have hoped for surrounding the release of the latest Intergovernmental Panel on ClimateChange (IPCC) report was urgently diverted to the breaking news story of Russia invading Ukraine. By Anders Lorenzen.
WMO Secretary-General Peterri Taalas laid the facts bare, stating: “Greenhouse gas levels are record high. This latest scientific analysis will undoubtedly increase pressure upon policy-makers and world leaders as, for the next two weeks, they will be striving to make progress on cutting emissions. Global temperatures are record-high.
A first ever trial on constitutional protections from climatechange is underway in Montana. Of note, there are state constitution based climatechange lawsuits against state governments pending in early stages of pleading in Hawaii , Utah , and Virginia. Supreme decisions?), Will it be effective?
That was the timeline laid down by the most prestigious body of climatescientists for limiting warming to 1.5 To assess how serious net zero pledges are from corporations, there are three fundamental questions one should ask: Are they including all greenhouse gas emissions? Source: Oil Change International.
But this simplified pathway misses a key step in cloud formation–and one that could help us combat climatechange. Altering cloud properties influences Earth’s climate On sunny days, it’s clear that clouds leave shadows on the landscape. Without these changes to clouds, the Earth would already be warmer.
Methane is responsible for 30 per cent of the current global temperature rise to date globally, and over 14 per cent of Canada’s annual greenhouse gas emissions. “A It outlines concern that fossil fuels like ‘natural’ gas and related carbon capture, utilization, and storage (CCUS) could be included under the sustainability label.
Youth4ClimateAction in Republic of Korea We are in a critical decade for action on climatechange. National governments are the most important systemic actors in the governance of climate action, primarily because they are the only actors with the ability to adopt economy-wide decarbonization measures.
Nearly every large food industry corporation today has pledged to combat climatechange by reducing its own carbon footprint. McDonald’s Accelerating Climate Action to Reach Net Zero Emissions by 2050 ). PepsiCo Doubles Down on Climate Goal and Pledges Net-Zero Emissions by 2040 ). ClimateChange , Walmart).
As the world grapples with the consequences of climatechange, many scientists have begun to face up to the realities of their carbon emissions. It turns out, for example, that climate-change researchers fly more frequently than scientists in other fields. But other scientists also fly a lot.
Writing as part of Frontiers’ guest editorials series, the study’s lead author – Prof Martin Siegert, deputy vice chancellor of the University of Exeter (Cornwall) – discusses how without there being a rapid shift to net-zero greenhouse gas emissions by 2050, the Antarctic environment will experience ever more drastic changes.
By Claire Hemlett An increasing number of food brands are turning to climate labels to boost sales. In the face of research that meat and milk are high in greenhouse gas emissions , companies are angling for new ways to reach eco-conscious consumers. Photo credit: Sentient Media. Our emissions are just too high at this point.
