According to The New York Times, scientists from the University of Hawaii at Manoa have calculated that by 2047, "plus or minus five years, the average temperatures in each year will be hotter across most parts of the planet than they had been at those locations in any year between 1860 and 2005."
To put it another way, for a given geographic area, the coldest year in the future will be warmer than the hottest year in the past, said Camilo Mora, the lead scientist on a paper published in the journal Nature.
Unprecedented climates will arrive even sooner in the tropics, Dr. Moras group predicts, putting increasing stress on human societies there, on the coral reefs that supply millions of people with fish, and on the worlds greatest forests.
Go back in your life to think about the hottest, most traumatic event you have experienced, Dr. Mora said in an interview. What were saying is that very soon, that event is going to become the norm.
Meanwhile, on the Washington Post, a study recently published in the scientific journal Nature, looks at which cities will reach "climate departure," -- a term to indicate when climate change has changed things to the point that the new weather is the new normal.
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. For example, let's say the climate departure point for D.C. is 2047 (which it is). After 2047, even D.C.'s coldest year will still be hotter than any year from before 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.
