Not exact matches

Siberian surface rock was loaded with carbon, resulting in runaway global warming as atmospheric CO2 levels more than doubled.

Like hundreds of millions of people, I share the fear of runaway global warming and ocean acidification, of losing the richness of life forms we humans share the planet with, of plastic and other toxics substances contaminating the biosphere.

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.

Evans continues demonstrating his misunderstanding of basic climate science with a reference to runaway global warming:

At Chevron, a similar resolution sought to make the oil company's current carbon emissions reduction goals more challenging by syncing the targets with the global emissions limits needed to prevent runaway global warming.

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..

The IPCC's climate science has long claimed that human CO2 emissions are producing an accelerated global warming, with a «runaway» warming trend, which is then being amplified in the north and south polar extremes.

He sums up the task with brutal candour: «the conclusion of this book is that we have only seven years left to peak global emissions before facing escalating dangers of runaway global warming.

The runaway greenhouse effect has several meanings ranging from, at the low end, global warming sufficient to induce out - of - control amplifying feedbacks, such as ice sheet disintegration and melting of methane hydrates, to, at the high end, a Venus - like hothouse with crustal carbon baked into the atmosphere and a surface temperature of several hundred degrees, a climate state from which there is no escape.

The claim that Earth is in the grips of runaway Global Warming took off with this chart.

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.

But of course that has nothing to do with the only issue that matters: will an increase in CO2 cause runaway global warming and climate catastrophe?

Dr. Lovelock, honored in 1997 with the Blue Planet Prize, which is widely considered the environmental equivalent of a Nobel award, has now come under attack from some environmentalists for his support of nuclear power as a way to avoid runaway «global heating» — his preferred alternative to «global warming.»
