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
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.”
“The information in this story is generally correct—the frequency and severity of flooding is accelerating due to sea level rise, and the quoted scientists from NOAA and FAU are credible experts in this field.”
“Overall, this piece accurately describes the findings of a new research paper by Mann et al on linkages between rapid Arctic warming and extreme weather at Earth’s more temperate latitudes. While there are a couple of statements that are overly confident given available evidence in the peer-reviewed literature, the author generally does an excellent job placing this new work into the broader context of related studies over the past decade.”
“The article clearly and concisely documents some of 2016’s climate extremes and puts them in the context of the warming trend.”
While natural temperature fluctuations (due to El Niño, for example) have always occurred, they are now superimposed on a warmer background due to human-induced global warming. That causes mass coral bleaching to happen more frequently.
