The idea that the sunny weather they enjoy may be a harbinger of
runaway climate change, that their beloved happy meal hamburgers are responsible for the release of dangerous methane gases and the unjust monopolization of vital water sources, and that the plastic refuse from their picnics might end up endangering the dolphins they idolize from afar — well, it's a lot to lay
on a child who's still not old enough to see the latest Star Wars.

On the very small scale, one could have a
runaway between whether or not a weather pattern has a thunderstorm at a specific time and place or whether it is dry and sunny at that specific time and place — but that's not the same as a change in
climate (see internal variability, chaos, butterfly effect).

One of the biggest debates between sceptics and their counterparts is in fact the role played by feedback mechanisms — a response in part to claims by environmentalists such as Mark Lynas in «Six Degrees: our future
on a hotter planet» that a relatively small increase in CO2 could cause «
runaway climate change» by triggering (unknown and possibly non-existent) feedback mechanisms to form.
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

on climate without a
runaway effect.
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 warming oceans push the release of methane from the sea floor, which could lead to
runaway climate change, etc..
A cadre of the world's top

runaway climate change that they are now sounding the alarm, putting the world
on notice that an extinction event may be in the cards.
What they are practicing is not science, it is propaganda based
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.
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.

Hansen began his career studying Venus, which was once a very Earth - like planet with plenty of life - supporting water before
runaway climate change rapidly transformed it into an arid and uninhabitable sphere enveloped in an unbreathable gas; he switched to studying our planet by 30, wondering why he should be squinting across the solar system to explore rapid environmental change when he could see it all around him
on the planet he was standing
on.
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

on CO2 production just to be
on the safe side.»
