about runaway warming.

runaway warming; and the impacts of ocean carbonization and acidification.
I do agree that Earth is not Venus — some scientists have already told me how much they hate the label «Venus effect,» but I find it informative, simply because it gives some idea
about the
runaway global
warming that did happen 5 times on Earth (which later, obviously, stabilized back to livable conditions).
And if we reach just shy of 3C

about 30M.

runaway»
warming Hawking insinuates that we suffer from?
About 1980ish, some old ideas like the greenhouse effect were brought out of mothballs and re-examined with new tools and techniques; simultaneously several researchers and theoreticians released their notes, published, or otherwise got together and there was a surprising consilience and not a small amount of mixing with old school hippy ecologism on some of the topics that became the roots of Climate Change science (before it was called Global
Warming); innovations in mathematics were also applied to climate thought; supercomputers (though «disappointing» on weather forecasting) allowed demonstration of plausibility of
runaway climate effects, comparison of scales of effects, and the possibility of climate models combined with a good understanding of the limits of predictive power of weather models.
You probably guessed that if the goal is to instill incentives that will bring
about big emission reductions fast enough to avoid
runaway global
warming, the answer is B, the marathon.
Such rapid
warming is problem [mostly] because it tells something
about global
warming we don't already know - it's unexplained [or indicates that some kind
runaway effect could be possible].
If the heat is hiding in the deep ocean it is not only unphysical, if true then it negates all arguments
about runaway atmospheric
warming anyway.
We will learn some things
about the CO2 greenhouse effect you have probably never heard in the media, such as the fact that
warming from CO2 is actually a diminishing return phenomenon whose effect is asymptotic or essentially capped, making it hard to understand the prevalence of wild, open - ended temperature
runaway scenarios.
Meanwhile, the logarithmic effect of CO2 is excellent «concession» to make in the rhetorical sense, since it concedes the obvious state of our knowledge
about the effects of CO2, while at the same time providing us with the solid argument that even if we double atmospheric CO2 levels from 400ppm to 800 ppm over the next 100 years the largest amount of
warming possible — assuming all else remains the same and Gaia has no homeostasis negative feedback systems which tend to moderate any
runaway trends — is 1.2 c.
CC can provide a perfectly adequate backdrop for a story — there's some decent SF that happens to be set in a world stricken by
runaway global
warming — but if it's all
about the message, then the tendency is towards something that's awkward, preachy, shrill, long - winded, unfunny (or unintentionally funny) or just plain dull.

runaway global
warming, as a consequence of ever - greater combustion of fossil fuels, could bring
about an ice - free polar ocean by
about 2050.
Positive feedback means
runaway warming «One of the oft - cited predictions of potential
warming is that a doubling of atmospheric carbon dioxide levels from pre-industrial levels — from 280 to 560 parts per million — would alone cause average global temperature to increase by
about 1.2 °C.
I don't care
about whether
runaway greenhouse
warming or volcanism or a celestial impact was what caused the atmosphere to become so dominated by CO2, only that CO2is keeping Venus» surface hot.
This
runaway effect that manmade climate change believers talk
about comes from the hypothesis that climate change feedback mechanisms are positive and the small
warming we have experienced will lead to drastic increases in global temperature.
We've outlined six things you need to know
about the level of emissions reductions needed to rein in
runaway warming.
Chuck, the quote seems pretty accurate to me, but some will cavil
about the use of the phrase «out - of - control
runaway warming process» for «each» of those systems; but there are certainly feedbacks associated with most of them that will indeed drive toward more
warming, though some effects are going to be stronger and faster than others.
Really, all this impotent oinking
about status here has nothing to do with the fact that the AGW contingent has no empirical, testable evidence showing that CO2 will lead to
runaway global
warming.
