Pruitt on Climate Change, Again

The head of the EPA told CNBC that he “would not agree” that “human activity,” or carbon dioxide emissions, is the “primary contributor” to global warming. But scientists say it’s “extremely likely” that human activity is the main cause of warming since the mid-20th century.

Precision in Climate Science

A number of President Trump’s cabinet members have said that scientists cannot precisely measure climate change nor the impact of human activity on climate change. That’s not accurate.

No Data Manipulation at NOAA

Top Republicans on the House science committee claim a former National Oceanic and Atmospheric Administration scientist “confirmed” that his NOAA colleagues “manipulated” climate data for a 2015 study. But that scientist denies that he accused NOAA of manipulating data.

Tillerson on Climate Change

During his confirmation hearing for secretary of state, Rex Tillerson said “our ability to predict” the effect of increased greenhouse gas concentrations in the atmosphere “is very limited.” That’s not entirely accurate.

The Candidates on Climate Change

We delve into the presidential candidates’ stances and claims on an issue that has received little attention in this campaign.

Stein Over the Top on Sea Level Rise

Green party presidential candidate Jill Stein cherry-picked the findings of a disputed study when she claimed that global warming would cause sea levels to rise on average “not one yard but many yards” in as soon as 50 years.

White House on Climate, Heat Deaths

In a recent “fact sheet” on the threat climate change poses to human health, the White House cherry-picked data on the estimated number of premature deaths due to future extreme temperatures.

Smith Still Wrong About Warming ‘Halt’

Rep. Lamar Smith at a recent hearing claimed a new study published in the journal Nature Climate Change “confirms the halt in global warming.” It doesn’t. In fact, the authors of the paper write, “We do not believe that warming has ceased.”

Cruz’s ‘Pseudoscientific’ Climate Claims

While on the campaign trail in New Hampshire, Republican presidential candidate Ted Cruz gave a speech to local residents that contained inaccurate and misleading claims about climate science and its terminology.
