🌍 #ClimateChange Getting hotter 🔥 / colder ❄️ ... or what ever I want?
Check out this neat illustrated thread on why "it hasn't warmed in 8 years" based on climate satellite data ... and what this claim has to do with cherry picking by @andrewdessler

A short 🧵 to explain why "it hasn't warmed in 8 years" is consistent with humans driving large warming over the century. To begin, let's consider the monthly satellite temperature record:
Of course they use the UAH dataset. They always do.
- TLT is *calculated* based on satellite data from other sources. It's not measurements. - the UAH dataset uses a different method for this calculation than all other satellite based datasets. - UAH also uses a different correction for drift of measurements than NASA, and the UAH "correction" removes part of the trend. - the UAH differs significantly from the other big datasets.
RealClimate: The climate summaries for 2019 are all now out. None of this will be a surprise to anyone who's been paying attention, but the results are stark.
@Bargdaffy I support your enthusiasm and passion, but it would certainly be beneficial to review the material first. But the added graphic is nice! Cheers
