Sentences with phrase «slow global warming since»

Not exact matches

In the particularly difficult question of global warming, thus far most economists have argued that it will be more efficient to respond to the problems caused by global warming as they occur than to make serious efforts to reduce it, since these efforts would slow economic growth.

Since methane can cause about 20 times as much atmospheric warming as carbon dioxide, curbing methane would help slow global warming.

What scientists discovered in 2014 is that since the turn of the century, oceans have been absorbing more of global warming's heat and energy than would normally be expected, helping to slow rates of warming on land.

[1] CO2 absorbs IR, is the main GHG, human emissions are increasing its concentration in the atmosphere, raising temperatures globally; the second GHG, water vapor, exists in equilibrium with water / ice, would precipitate out if not for the CO2, so acts as a feedback; since the oceans cover so much of the planet, water is a large positive feedback; melting snow and ice as the atmosphere warms decreases albedo, another positive feedback, biased toward the poles, which gives larger polar warming than the global average; decreasing the temperature gradient from the equator to the poles is reducing the driving forces for the jetstream; the jetstream's meanders are increasing in amplitude and slowing, just like the lower Missippi River where its driving gradient decreases; the larger slower meanders increase the amplitude and duration of blocking highs, increasing drought and extreme temperatures — and 30,000 + Europeans and 5,000 plus Russians die, and the US corn crop, Russian wheat crop, and Aussie wildland fire protection fails — or extreme rainfall floods the US, France, Pakistan, Thailand (driving up prices for disk drives — hows that for unexpected adverse impacts from AGW?)

«Note: LOTI provides a more realistic representation of the global mean trends than dTs below; it slightly underestimates warming or cooling trends, since the much larger heat capacity of water compared to air causes a slower and diminished reaction to changes.»

Other than that, there is «Some skeptics, however, have suggested that the rise in global temperatures has actually slowed since 1998, which was itself a record - warm year.»

Terrell Johnson, reporting on a recent NASA publication concluding that deep ocean temperatures have not increased since 2005 (http://www.weather.com/science/environment/news/deep-ocean-hasnt-warmed-nasa-20141007): «While the report's authors say the findings do not question the overall science of climate change, it is the latest in a series of findings that show global warming to have slowed considerably during the 21st century, despite continued rapid growth in human - produced greenhouse gas emissions during the same time.»

Richard Allan, reader in climate science at the University of Reading, said: «Global warming is not «at a standstill» but does seem to have slowed down since 2000 in comparison to the rapid warming of the world since the 1970s.»

There is no statistical evidence of a recent slow - down of global warming, nor is there evidence of accelerated warming since the mid-20th century.

However, another important recent paper by Kevin Cowtan and Robert Way showed that the global surface temperature rise has not slowed as much as some previously thought; in fact, the surface warming since 1997 happened more than twice as fast as previous estimates.»

They conclude that while the rate of increase of average global surface temperatures has slowed since 1998, melting of Arctic ice, rising sea levels, and warming oceans have continued apace.

The slow rate reflects that there has been little room to grow, because the consensus on human - caused global warming has generally always been over 90 % since 1991.

They write in Geophysical Research Letters > that since 1999 the IPO has been perhaps keeping the world cooler than it might have been, as the rate of increase in global warming appeared to slow between 1998 and 2012.

IPCC: It is very likely that the global warming of 4 °C to 7 °C since the Last Glacial Maximum occurred at an average rate about 10 times slower than the warming of the 20th century.

The slowdown in warming was, she added, real, and all the evidence suggested that since 1998, the rate of global warming has been much slower than predicted by computer models — about 1C per century.

Note: LOTI provides a more realistic representation of the global mean trends than dTs below; it slightly underestimates warming or cooling trends, since the much larger heat capacity of water compared to air causes a slower and diminished reaction to changes; dTs on the other hand overestimates trends, since it disregards most of the dampening effects of the oceans that cover about two thirds of the Earth's surface.

Since I wrote one of the first books for a general audience about global warming way back in 1989, and since I've spent the intervening decades working ineffectively to slow that warming, I can say with some confidence that we're losing the fight, badly and quickly — losing it because, most of all, we remain in denial about the peril that human civilization iSince I wrote one of the first books for a general audience about global warming way back in 1989, and since I've spent the intervening decades working ineffectively to slow that warming, I can say with some confidence that we're losing the fight, badly and quickly — losing it because, most of all, we remain in denial about the peril that human civilization isince I've spent the intervening decades working ineffectively to slow that warming, I can say with some confidence that we're losing the fight, badly and quickly — losing it because, most of all, we remain in denial about the peril that human civilization is in.

The «note» you refer to goes: «Note: LOTI provides a more realistic representation of the global mean trends than dTs below; it slightly underestimates warming or cooling trends, since the much larger heat capacity of water compared to air causes a slower and diminished reaction to changes; dTs on the other hand overestimates trends, since it disregards most of the dampening effects of the oceans that cover about two thirds of the earth's surface.»
