It may seem surprising to people, but you can look at something like Mars, which has a very thin atmosphere, and you can look at something like Venus which we tend to think of as sort of having this rather heavy, clouded atmosphere, which [is] hellishly
warm because of
runaway greenhouse effect, and
on both of those planets you are seeing this phenomenon of the atmosphere leaking away, is actually what directly has led to those very different outcomes for those planets; the specifics of what happened as the atmosphere started to go in each case [made] all the difference.

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.
These tipping points could be ice sheets
on Greenland and Antarctica melting permanently, global food shortages and widespread crop failures with more extreme weather, rising ocean temperatures and acidity reaching triggering a crash in global coral reef ecosystems, and

runaway climate change, etc..

on an unsupportable catastrophic AGW agenda designed to convince the public that a rise in a tiny trace gas comprising only 0.00038 of the atmosphere will cause
runaway global
warming and climate catastrophe.
Endangered Species Act protection is necessary to safeguard
warming - threatened mountain species from all threats, as well as protecting their habitats — and the planet — from

warming by helping spur strong measures to reduce greenhouse gas emissions
on the local, national and international scale.
In a sharp change from its cautious approach in the past, the National Academy of Sciences
on Wednesday called for taxes
on carbon emissions, a cap - and - trade program for such emissions or some other strong action to curb
runaway global
warming.Such actions, which would increase the cost of using coal and petroleum — at least in the immediate future — are necessary because «climate change is occurring, the Earth is
warming... concentrations of carbon dioxide are increasing, and there are very clear fingerprints that link [those effects] to humans,» said Pamela A. Matson of Stanford University, who chaired one of five panels organized by the academy at the request of Congress to look at the science of climate change and how the nation should respond.
A new Ice Age could descend
on us all, but Socrates would still be looking for ways to keep his alarmist faith in man - made
runaway global
warming alive.
This explains why the very high carbon dioxide levels in geologic history never caused any
runaway warming It also tells us that burning fossil fuels can not lead to
runaway warming like happened
on Venus according to Hansen.
It never ceases to amaze me that scientists
on both sides claim to be certain that they know exactly how all of this stuff works and that their pronouncements concerning whether we will experience
runaway warming or start the next glacial episode are correct.
Positive feedback won't lead to
runaway warming; diminishing returns
on feedback cycles limit the amplification.

on the earth perished, apparently from
runaway global
warming.
Bottom Line Henry: I am
on your side in that I do not think there is any kind of Global
Warming «tipping point» or «runaway warming» crisis, nor has there be

runaway warming» crisis, nor has there be
warming» crisis, nor has there been one.
In light of the consequences that

Regarding that last point, consensus climate science has proposed a hypothesis
on the claim that climate physics dictates that rising atmospheric CO2 levels will
warm the atmosphere substantially, thus causing a positive feedback loop, which will then continuously accelerate
warming until a tipping point of
runaway temperatures take place, turning Earth into the next Venus.
More importantly, the HC4 temperature dataset verifies what the prior article
on the satellite dataset established: despite multiple major
warming El Nino events, and with over 60 % of all 1850 - 2016 total CO2 emissions being released since 1979, there is absolutely zero indication of a positive feedback's existence producing a
runaway, «tipping point»
warming acceleration.
The consensus regarding the catastrophic global
warming hypothesis is completely reliant
on a proposed positive feedback producing
runaway global

Either the switch is «
on» (global
warming — the catastrophic,
runaway variety, one assumes — is «happening» and humans are causing it) or the switch is «off» (global
warming isn't happening at all, and it's entirely «made up».)
If you get beyond the hard core of near religious believers in the massive
warming scenarios, the average global
warming supporter would answer this paper by saying: «Yes there is a lot of uncertainty, but though the doomsday
warming scenarios via
runaway positive feedback in the climate can't be proven, they are so bad that we need to cut back
on CO2 production just to be
on the safe side.»
