Fred Singer incorrectly claims sea level rise is not caused by climate change
Claim:
Sea-level rise does not seem to depend on ocean temperature, and certainly not on CO2

-1.8Very lowWall Street Journal commentary grossly misleads readers about science of sea level rise
“The article has almost nothing to do with the modern state of sea-level science. The author tries to call into question that global warming causes sea-level rise, and does so by cherry-picking a short segment of data from 1915-1945, a time when data quality is poor and the warming signal small—a bizarre approach that could never pass scientific peer review and is apparently aimed at misleading a lay audience.”

MisleadingNatural variability can not explain modern global warming, as Heartland Institute report claims
Claim:
Neither the rate nor the magnitude of the reported late twentieth century surface warming (1979–2000) lay outside normal natural variability.

IncorrectA lull in solar activity would have little effect on global temperatures; claims of “global cooling” are not based on science
Claim:
Forward projections of solar cyclicity imply the next few decades may be marked by global cooling rather than warming, despite continuing CO2 emissions.

InaccurateGlobal 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

Flawed reasoning
CO2 is a greenhouse gas that caused warming during past climate changes, notably as a feedback amplifying other factors
Claim:
Increases in atmospheric CO2 followed increases in temperature. Therefore, CO2 levels could not have forced temperatures to rise.

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

Heartland Institute report incorrectly claims no evidence of human impacts in melting ice
Claim:
Melting of Arctic sea ice and polar icecaps is not occurring at ‘unnatural’ rates and does not constitute evidence of a human impact on the climate.

InaccurateGlobal sea level rise is accelerating, despite Heartland Institute report’s claims otherwise
Claim:
Best available data show sea-level rise is not accelerating. Local and regional sea levels continue to exhibit typical natural variability—in some places rising and in others falling.

IncorrectThe Sun cannot explain recent global warming, contrary to what Heartland Institute report claims
Claim:
Solar forcings are not too small to explain twentieth century warming. In fact, their effect could be equal to or greater than the effect of CO<sub>2</sub> in the atmosphere.
