CLAIMS REVIEWED

Global warming has not “ceased”, as Heartland Institute report falsely claims

CLAIM
"global warming ceased around the end of the twentieth century and was followed (since 1997) by 19 years of stable temperature"

SOURCE: Craig Idso, Robert Carter, S. Fred Singer, Heartland Institute, 2016

VERDICT

Climate sensitivity estimate given in Heartland Institute’s report is misleading

CLAIM
"Doubling the concentration of atmospheric CO2 from its pre-industrial level, in the absence of other forcings and feedbacks, would likely cause a warming of ~0.3°C to 1.1°C"

SOURCE: Craig Idso, Robert Carter and S. Fred Singer, Heartland Institute, 2017

VERDICT

Wall Street Journal op-ed ignores evidence of negative impacts of increasing CO2

CLAIM
"Increased atmospheric carbon dioxide has helped raise global food production and reduce poverty."

SOURCE: Harrison Schmitt & Rodney Nichols, The Wall Street Journal, 31 Oct. 2016
