By the end of this century, according to the new research, some «megapolitan» regions of the U.S. could see
local average temperatures rise by as much as 3 degrees Celsius, in addition to whatever global warming may do.
Not exact matches
with
local weather patterns, but the consistent
rise in
average global
temperatures.
Cuomo joined California in signing on to the Under 2 MOU, an agreement between states, provinces and
local governments across the world to cap the
rising average temperature by the year 2100.
The point is that comparing
local averages of past with
local extremes of the present selects strongly cases where the
local temperatures have
risen more than the
average of all locations even in absence of extremes.
Like in school when the class
average mark goes up 10 marks does not mean that the whole class got exactly 10 marks more, the actual
local temperature rise will depend on your location, wind patterns etc..
The glacier remained relatively stable from 1960 to 2002, coinciding with cooler - than -
average local summer
temperatures through the mid - 1990s.3 After
local summer
temperatures began to
rise, around 1995, Kangerdlugssuaq's speed more than doubled, from an
average of 49 feet (15 meters) per day in 2001 to 131 feet (40 meters) per day in 2005.6
They show the projected
local temperature change (on the y - axis) for every degree of global
average temperature rise (x-axis).
The important line to note is the dashed black line, which indicates how
local temperatures would change if they
rose at the same rate as the global
average.
IMHO the emphasis on global
average surface
temperature in recent times, while understandable (if it really does
rise 3 + K this century, the emphasis will have been justified) distracts from other issues that are just as important for
local climate (which is what we all actually experience).
