Not exact matches

Perhaps this is why there are long term warm / cold climatic cycles, rather than runaway heat or cold.

This chemical weathering process is too slow to damp out shorter - term fluctuations, and there are some complexities — glaciation can enhance the mechanical erosion that provides surface area for chemical weathering (some of which may be realized after a time delay — ie when the subsequent warming occurs — dramatically snow in a Snowball Earth scenario, where the frigid conditions essentially shut down all chemical weathering, allowing CO2 to build up to the point where it thaws the equatorial region, at which point runaway albedo feedback drives the Earth into a carbonic acid sauna, which ends via rapid carbonate rock formation), while lower sea level may increase the oxidation of organic C in sediments but also provide more land surface for erosion... etc..

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.

However, you have avoided my last comment that without a positive feedback from water vapour there is no chance of runaway global warming arising from increasing atmospheric CO2 levels.

«A recent article in The Gisborne Herald said «warming has been accelerating over the past 20 years», and there is «a runaway greenhouse effect», and «rising sea levels», but none of these things are real.

There was never runaway warming on Venus, and a bit more attention to the evidence, as Harry Huffman has done, shows the Venusian CO2 = warming is simply bad science.

As it stands there's no empirical evidence of any sort that CO2 causes climate warming, and indeed now the ipcc is maintaining that CO2 is both a cause and an effect of temperature change, which, unless CO2 was only an insignificant contributor to warming, would without a doubt lead to a runaway greenhouse with boiling oceans.

1) CO2 concentrations in the past have more than once been several thousands of ppm, there was NO runaway global warming.

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.

2) Whilst not believing that co2 will cause runaway warming and that carbon should remain an important mainstay of our energy requirements for years to come, there are nevertheless compelling reasons to look for cost effective alternatives, not least to secure cheap and reliable energy security.

It should be self - evident that clouds have to provide a negative feedback, or there would be regular runaway «global warming» events in the geological record.

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.

Was there runaway global warming, and, if so, how did life forms manage to evolve in what AGW proponents argue should have been extremely hostile conditions?

There is no global harm identified due to the rise in CO2, which has been up to 20X higher in the past without ever triggering runaway global warming — the scare that started it all.

There is no indication of any trend in that data - nor is there in the instrumental data for the past 150 years for that matter - of any runaway global warming actually happening or credibly projeThere is no indication of any trend in that data - nor is there in the instrumental data for the past 150 years for that matter - of any runaway global warming actually happening or credibly projethere in the instrumental data for the past 150 years for that matter - of any runaway global warming actually happening or credibly projected.

There are government funded scientists (Mann, Hansen) who expected runaway warming.

Logarithmic diminution effect explains why there wasn't any run ¬ away «green ¬ house» warming way in dinosaur days when atmospheric CO2 levels were several thousands of ppm, and why (try as they might to convince us) there can't ever be runaway warming now.

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.

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 beWarming «tipping point» or «runaway warming» crisis, nor has there bewarming» crisis, nor has there been one.

So there is no chance of runaway warming.

Every time there is a «hottest» day, a «warmest - than - ever» month, or an extended period of quickly rising global temps, there are many who instantly claim that the world has reached a runaway climate change condition, or a global warming tipping point, or a soon to be doomsday, a no - return cascade 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.

How many civilization are out there which caused a warm climate shift or runaway state?

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.

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.»
