Sentences with phrase «with runaway climate change»

A new study suggests the idea, seen as a last - ditch way to deal with runaway climate change, could cut rainfall in the tropics by 30 %.

Not exact matches

This article minimizes what credibly could be the largest challenge in dealing with climate change: Holding the atmosphere to a CO2 content no greater than 450 PPM to prevent an increase of no more than 2 degrees C, beyond which runaway growth in CO2 could occur from natural sources.

With an 80 % reduction in GHGs by 2050 we have a 50 % chance of dangerous climate change or runaway global warming.

Once the ice reaches the equator, the equilibrium climate is significantly colder than what would initiate melting at the equator, but if CO2 from geologic emissions build up (they would, but very slowly — geochemical processes provide a negative feedback by changing atmospheric CO2 in response to climate changes, but this is generally very slow, and thus can not prevent faster changes from faster external forcings) enough, it can initiate melting — what happens then is a runaway in the opposite direction (until the ice is completely gone — the extreme warmth and CO2 amount at that point, combined with left - over glacial debris available for chemical weathering, will draw CO2 out of the atmosphere, possibly allowing some ice to return).

So, for that case with rapid northern temperature change and other rapid changes in the climate system, the methane acted as a feedback, fast enough to be considered in economic planning, but not so fast that most people would consider it a runaway.

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 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 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 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 climate models combined with a good understanding of the limits of predictive power of weather models.

A concern with «large» climate changes (i.e., on the scale of snowball Earths or runaway greenhouses) is that there's bifurcation (loosely, tipping points) in the system.

Rather than replacing this energy source with fossil fuels, thus boosting carbon emissions and encouraging runaway climate change, the world can use this opportunity to pursue a much safer electricity sector powered largely by wind, solar, and geothermal energy.

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..

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.

It's an appropriate name for a group that's attempting to slow some of the runaway misinformation about climate change, by doing what scientists do with their published work: review it.

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.

21 March, 2018 — Runaway climate change will alter the pattern of ocean productivity and circulation and play perhaps irreversible havoc with fish catches.
