A city hits "climate departure" when the average temperature of its coolest year from then on is projected to be warmer than the average temperature of its hottest year between 1960 and 2005. [...] Put another way, every single year after 2047 will be hotter than D.C.'s hottest year on record from 1860 to 2005. It's the moment when the old "normal" is really gone.
Well, which is it, 1960-2005 or 1860-2005?
- GeneralMayhem 13y agoIt doesn't excuse the author's inconsistency, but the reality is that it doesn't matter - the difference between 1860 and 1960 is trivial compared to the difference after that. The hottest year on record between 1860 and 2005 is probably after 1990 in most cities.
- rtpg 13y agoI'm guessing it's 1860 (around the beginning of most good record keeping).
