see as potential benefits of
climate change.
Just as many of the home runs hit by a baseball player on steroids were almost certainly due to the taking of steroids — even if you can't prove that any one home run resulted from it — so too is it likely that the record - breaking heat we are
seeing in the U.S. this summer of 2012 is very likely due, in substantial part, to the impact of human - caused
climate change and
global warming.
The
warming effect of CO2 on
climate is physically well - understood, and the sensitivity of
global temperature to CO2 is independently confirmed by paleoclimatic data,
see e.g. Rohling et al. 2012 or the brand - new paper by Friedrich et al. 2016 (here is a nice write - up on this paper from Peter Hannam in the Sydney Morning Herald).

So, to be «CLEAR»,...
Climate «Change» (current or more «recent» euphemism for
Global «
Warming») is NOT synonymous with, oh... let me
see... «WEATHER»... the «SEASONS» («Duh?!?»)... or, the «NATUR» (AL) operation of the Earth (our World).
Polar amplication is of
global concern due to the potential effects of future
warming on ice sheet stability and, therefore,
global sea level (
see Sections 5.6.1, 5.8.1 and Chapter 13) and carbon cycle feedbacks such as those linked with permafrost melting (
see Chapter 6)... The magnitude of polar amplification depends on the relative strength and duration of different
climate feedbacks, which determine the transient and equilibrium response to external forcings.
The physics argument seems simply that (1) past
climates have been very different from today (true); (2) the changes are large compared to what we
see from

see, anytime soon (true).

After following the
global warming saga — science and policy — for nearly a quarter century, I've
seen the biases at the journals and N.S.F. (including their press releases sometimes), in the I.P.C.C. summary process (the deep reports are mainly sloppy in some cases; the summary writing — read the
climate - extinction section of this post — is where the spin lies), and sometimes in the statements and work of individual researchers (both skeptics and «believers»).
It isn't a pause in

If environmental groups and their backers want to
see concrete progress on limiting the risk that humans will propel dangerous
global warming, they may need more than just additional money and better organization, but also a hard look at core strategies and a philosophy that has long cast
climate change as primarily a conventional pollution problem, not a technology problem.
