warming over next few decades, will cause animal extinction, and will melt Greenland in some dramatic fashion, and will continue cause increase in crop production and a general increase in global vegetation.

warming over the next few decades — with a particular focus on China.
General circulation models predict that global
warming over the next few decades will occur mainly in the polar regions.
Until you do, I'm staying focused on the next century or so, when my nephews and neices and their future children will be struggling with the consequences of global
warming over the next few decades.
Further, a large ensemble of climate model realizations reveals that additional global
warming over the next few decades is very likely to create ∼ 100 % probability that any annual - scale dry period is also extremely warm.

next few decades under the IS92a scenario.
I can understand that approaching equilibrium takes a long, long time, while TCR gives a better measure of what will happen
over the
next few decades (and that technology and society may be very different in 200 years time); but on the other hand, I thought nations had agreed to try to limit global
warming to less than 2 degrees C overall, and not just to limit it to less than 2 degrees C by 2100.

Mitigation
over the
next few decades will be pivotal in determining the amount of long - term
warming and associated risks.
Our activities are
warming the world's atmosphere at such a rate that most of our agriculture will be seriously dislocated
over the
next few decades — even if we were to get down to business now and start controlling our emissions of carbon dioxide and other greenhouse gases.
You seem to have gone to quite some length in creating an impressive straw man, which doesn't really need dealing with in detail, since I can simply jump to the end - point and agree that
warming in excess of 0.325 C /
decade is indeed unlikely
over the
next few decades.
Such large variations of the climate likely won't occur every year
over the
next few decades given the limited global
warming to date, but it would seem likely such conditions will occur more and more frequently as global
warming continues, disrupting both social systems and ecosystems.
«'' Until we can model this lower - frequency behaviour in the tropical Pacific, one can only speculate on how the
warming will play out
over the
next few decades,» said lead author Dr Michael Griffiths from William Paterson University, in the United States.»
Global
warming could increase the number of hungry in the world in 2080 by anywhere between 140 million and 1 billion, depending on how much greenhouse gas is emitted into the air
over the
next few decades.
A flurry of recent research strongly suggests that recent observations like these are indeed linked to California's long - term
warming trend — and that snowpack losses are expected to accelerate further
over the
next few decades.
As these glaciers retreat due to global
warming (see Chapter 1), river flows are increased in the short term, but the contribution of glacier melt will gradually decrease
over the
next few decades.
No one in his right mind (least of all the ocean dwellers) cares a whit whether or not the ocean is
warming by a
few thousandths of a degree
over the
next several
decades.
A certain amount of continued
warming of the planet is projected to occur as a result of human - induced emissions to date; another 0.5 °F increase would be expected
over the
next few decades even if all emissions from human activities suddenly stopped, 11 although natural variability could still play an important role
over this time period.12 However, choices made now and in the
next few decades will determine the amount of additional future
warming.
Reductions in some short - lived human - induced emissions that contribute to
warming, such as black carbon (soot) and methane, could reduce some of the projected
warming over the

decades, because, unlike carbon dioxide, these gases and particles have relatively short atmospheric lifetimes.The amount of
warming projected beyond the
next few decades is directly linked to the cumulative global emissions of heat - trapping gases and particles.
