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).
Not exact matches
On a related note, is a «
runaway greenhouse» effect impossible, given the current data and understanding
about global warming?
(1) What proof do government bureaucrat «scientists» provide that they are right
about predictions of
runaway global warming?
In light of the recent IPCC report released this past week and stating essentially that
global warming is a
runaway train that can't be stopped for centuries, it may be tempting to give up hope for a brighter future... But like any patient who suffers from a chronic disease that is potentially fatal, not only is education
about the condition itself essential, but also what we can do to help mitigate its impact.
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].
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.
For more than two decades, meteorologists and oceanographers have repeatedly warned that
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.
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.
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.
