How CO2 warms Earth through the greenhouse effect and why CO2 is not ‘saturated’ in Earth’s atmosphere
There is no doubt about it – climate science can be complex. But sometimes this complexity is mistaken for uncertainty.…

1HighGuardian coverage of essay on potential of future "hothouse" climate is generally accurate, but misstates some details
“The article reasonably summarizes a new study published in PNAS, which describes the potential of tipping elements to enhance climate warming and the potential for the Earth to transition into a hot-house climate state. The article is careful to point out uncertainties and thus avoids being sensational. However, there are many small errors scattered throughout the article.”

-1LowFinancial Post commentary misleads about warming effect of greenhouse gas emissions by cherry-picking studies
“This article selectively cherry-picks studies showing low climate sensitivity, leaving out whole lines of evidence (e.g. paleoclimate studies) that agree with the sensitivity estimates found in models. It also glosses over the many criticisms of instrumentally based (or “energy balance”) sensitivity estimates published in recent years.”

IncorrectProf. John Christy incorrectly claims to show climate models are too sensitive to carbon dioxide
Claim:
the real atmosphere is less sensitive to CO2 than what has been forecast by climate models

Incorrect
Heartland Institute report’s claim that climate models are too sensitive to CO2 does not reflect evidence
Claim:
[climate models] systematically over-estimate the sensitivity of climate to carbon dioxide ... and modelers exclude forcings and feedbacks that run counter to their mission

Misleading
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
