Last month was easily the hottest November on record globally, according to satellite data sets.
…In fact, satellite data, ground-based weather stations, sea-based buoys, and even weather balloons all reveal a steady long-term warming trend. These satellites have documented a steady warming of the troposphere (the lower atmosphere). It always bears repeating that the satellites indirectly measure the temperature where we don’t live (the troposphere), so the data need a whole bunch of (easily screwed up) adjustments before it is useful to anyone. If you want a direct measure of the temperature at the surface where we actually live and grow food, you need NASA’s land and ocean temperature index (LOTI) from the Goddard Institute for Space Studies (GISS):
So, no matter how we look at it, we are warming rapidly. And carbon pollution is the primary cause. In fact, as I’ve written, the best estimate by climate scientists is that humans are responsible for all of the warming we have suffered since 1950…
Despite this, the denier-led House Science Committee tweeted out an erroneous Breitbart story last week about some satellites showing cooling. The story was quickly debunked by actual scientists here and everywhere.
