I cannot find any reason to doubt these conclusions, can you?
Estimating the warming rate for each, the highest rate is for the data from Cowtan & Way, a whopping 1.91 ± 0.24 °C per century. The “±” indicates a 95% confidence interval, so the real rate is almost surely between 1.67 and 2.15 °C per century. At those rates, we’ll reach extremely bad sometime between 2036 and 2042….
Bottom line: at the rate we’re going, we’ll hit extremely bad, possibly intolerable, probably between 2040 and 2045. Maybe a couple years later, maybe a couple years earlier, but it’s not far away. Most of you reading this will still be around when it happens. Your kids will be. We’re headed for a cliff and it’s not far away.
Nobody knows if volcanic activity will buy us more time or something else, but intolerable temperatures, widespread climate-related disasters, extreme weather events and crop failures are now a guaranteed part of our collective futures. And now, with Trump rolling back environmental protection, coal-fired power plants and pretty much ignoring all the things we SHOULD be doing – it’ll come at us even faster and worse sooner.
