Claim:
Forward projections of solar cyclicity imply the next few decades may be marked by global cooling rather than warming, despite continuing CO2 emissions.
Claim:
global warming ceased around the end of the twentieth century and was followed (since 1997) by 19 years of stable temperature
Claim:
Increases in atmospheric CO2 followed increases in temperature. Therefore, CO2 levels could not have forced temperatures to rise.
Professor of economics Gary Yohe explains that the claim Sen. Rand Paul relies on is flawed and not consistent with current scientific knowledge.
“Generally scientifically sound, but caution should be displayed before basing discussion solely on a single modeling study, especially when it incorporates fundamentally different processes relative to other contemporary models.”
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
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.
“The article contains little to no rational treatment of observational data, but relies on heavily biased secondhand interpretation… Even the title is based on a lie. There is no ‘study’ that finds static temperatures for 19-years. This article is based on a newspaper article that makes this false statement based in turn on a blog post…”
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.
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.
