SciCheck
FactCheck.org’s SciCheck feature focuses exclusively on false and misleading scientific claims that are made by partisans to influence public policy. It was launched in January 2015 with a grant from the Stanton Foundation. The foundation was founded by the late Frank Stanton, president of CBS for 25 years, from 1946 to 1971.

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.

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.

We’re happy to announce that SciCheck is now entering its third year with the continued support of the Stanton Foundation.
Sanders and Pruitt Rumble Over Earthquakes
Sen. Bernie Sanders claimed that “the cause of” the spike in earthquakes in Oklahoma “is fracking.” But it’s more complicated than that.
Trump on Torture, Again
