“This article suffers from a common error in reasoning. The author focuses on individual “snapshots” of the state of the climate while ignoring the long-term trends. Those trends occur over many decades and must be observed/considered over those time scales.”
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.
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
the New York Times opinion section itself apparently didn’t realize that the content of Mr. Stephens’ piece did not actually support the message of the push notification that was introducing the article…
“Dr. Happer’s assertion that models show 2x to 3x greater warming than observations is incorrect. At the surface (where we all live) models predict a rate of warming of 0.2 °C per decade since 1970, while NASA observes warming of around 0.18 °C during the same period.”
Claim:
The temperature is not rising nearly as fast as the alarmist computer models predicted. You know, it’s much, much less, factors of 2 or 3 less.
Claim:
there's this myth that's developed around carbon dioxide that it's a pollutant […] Carbon dioxide is a perfectly natural gas, it’s just like water vapor, it’s something that plants love.
Declining Arctic sea ice cover and thawing permafrost are both complex feedbacks that amplify global warming: The loss of reflective sea ice means more sunlight absorbed by the dark Arctic Ocean, while thawing permafrost can release greenhouse gases to the atmosphere.
“The article is accurate and highlights the challenges that California’s water resource managers are facing due to climate change. There are some issues with differentiating natural climate variability and forced climate change but the main points are correct.”
