Explainer: How the rise and fall of CO2 levels influenced the ice ages


The Earth’s climate has been quite stable over the past 11,000 years, playing an important role in the development of human civilisation. Prior to that, the Earth experienced an ice age lasting for tens of thousands of years. The global average temperature was around 4C cooler during the last ice age than it is today. There is a real risk that, if emissions continue to rise, the world warms more this century than it did between the middle of the last ice age 20,000 years ago and today.

Responding to Stossel TV video on our rating process


During their interviews, the scientists were pressed for judgments on whether the rating we applied was appropriate. Clips from these interviews were then used in Stossel’s new video to attempt to discredit our rating. However, both Zeke Hausfather and Stefan Doerr subsequently discussed the video with us and both agree the rating was appropriate—a fact that Stossel noted in his video.

The potentials and limitations of tree plantings as a climate solution


the international conversation on tree plantings as a solution to reducing CO2 emissions in the atmosphere and mitigating the rise in global surface temperature is mixed, with judgments ranging from helpful to harmful. For example, an article in The Guardian says tree planting “has mind-blowing potential” to tackle climate change, whereas an article in Slate says it won’t stop climate change and may “do more harm than good.”

“Planet of the Humans” documentary misleads viewers about renewable energy


Instead of presenting life cycle analyses for solar and wind generation or quantifying electric vehicle emissions that could inform viewers, Planet of the Humans misleads with broad claims that are not supported by scientific evidence. Unfortunately, these omissions and inaccuracies substantially shape the conclusions the film presents to its audience.

How is Arctic warming linked to the ‘polar vortex’ and other extreme weather?


Over the past decade, a growing body of research has proposed ways in which rapid Arctic warming can lead to harsh winters, summer heatwaves and even floods and droughts across the mid-latitudes. Some scientists say that climate change and Arctic sea ice loss are the root cause of these events, but others are more circumspect. In this detailed Q&A, scientists discuss the potential connections between Arctic warming and extreme weather across the mid-latitudes, what those theories look like, and how the evidence measures up.

How credible were 2018’s most popular climate articles?


Compared to last year’s top 10, there is a notable lack of low credibility stories. Two stories garnered mixed reviews from scientists. In one case, this was an article detailing false claims about sea level rise made by politicians, in which some reviewers felt the article simply wasn’t clear enough in its corrections. But there were no articles from partisan outlets presenting inaccurate rejections of climate system at the top in 2018. Instead, the list was dominated by major news outlets—with the exception of the top story, which was published by the local FOX station in St. Louis.

Is President Trump right that polar ice caps are setting records for growth, instead of melting?

We are not heading towards a “mini ice age”, contrary to claims in some media


Recently, alarming claims that we are heading towards a “mini ice age” have been popping up across the web. This was the subject of a widely discussed Metro article titled “A mini ice age could be on the way which means it will get very, very cold”. Similar claims were also repeated without verification throughout … Continued
