Sentences with phrase «considerable average warming»
Summing up: My question for sTeve is: why would you choose the GISS estimate of temperatures, which shows parts of the past decade as higher than 1998 and considerable average warming, over the other three monitoring agencies, which show much less or no warming for the decade?

However, this average rate hides considerable variations in the rate and magnitude of warming.
spalding craft (2)-- Actually, there is an overwhelming abundance of evidence that the climate warmed to a maximum, so - called optimum, temperature at different times in different regions, but about 8 — 6 thousand years ago; it had been cooling, on average since until humans started added considerable quantities of global warming (so - called greenhouse) gases started in, say, 1850 CE.
bozzza - The differences in the Arctic are perhaps 1/4 the ocean thermal mass as global ocean averages, small overall size (the smallest ocean), being almost surrounded by land (which warms faster), more limited liquid interchanges due to bottlenecking than the Antarctic, and very importantly considerable susceptibility to positive albedo feedbacks; as less summer ice is present given current trends, solar energy absorbed by the Arctic ocean goes up very rapidly.
The increase is due to a considerable and rapid warming near the polar region that has averaged 2 times the larger global warming rate (about 0.15 to 0.2 C per decade for the world and 0.3 to 0.4 C per decade for the Arctic).
On the other hand you could say that the LIA was «normal» and ignore that warming of the oceans has considerable impact on the global temperature average and credit CO2 with 100 % (even 110 %) of the warming from any period you like.
