New NASA model: Doubled CO2 means just 1.64°C warming


You're not as skeptical as you think you are

If any of you had actually read the report being cited here and not just the malformed attempt at interpretation by this article you would know that this is all hogwash. The point of the report was not a climate projection, just an attempt at quantifying the negative feedback of plant transpiration, which they settled on 0.26 degrees Celsius. The 1.64 number is a result of subtracting 0.26 (well 0.3 which was rounded up in the NASA press release) from the LOWEST predicted temperature increase by CO2 of 1.94 degrees Celsius, when in fact the temperature increase ranges cited in the report are 1.94 to 4.5 degrees Celsius, so in fact this report says that if CO2 concentrations double, we should expect a temperature increase from 1.64 to 4.2 degrees celsius, down from 1.94 to 4.5 degrees Celsius when we account for plant transpiration.

A perfect example of people not reading past the headlines and doing zero critical thinking for themselves. This report doesn't debunk global warming. The so-called "cooling trend" you talk about is just as easily debunked and if you have any interest in knowing the actual science or in real skeptisism please feel free to let me know and I'll gladly oblige.
