Sentences with phrase «rate of surface warming during»

«stratospheric water vapor probably increased between 1980 and 2000, which would have enhanced the decadal rate of surface warming during the 1990s by about 30 % as compared to estimates neglecting this change.

Meehl and Teng recently showed that when this is done, thereby turning a model projection into a hindcast, the models reproduced the observed trends — accelerated warming in the 1970s and reduced rate of surface warming during the last 15 years — quite well.

Not exact matches

The deceleration in rising temperatures during this 15 - year period is sometimes referred to as a «pause» or «hiatus» in global warming, and has raised questions about why the rate of surface warming on Earth has been markedly slower than in previous decades.

The results, presented here at the AAAS annual meeting on 14 February, showed that when the sea surface warmed off the coast of Peru in 1997 - 98, during El Niño, there was a marked increase in rates of cholera infection in Lima and nearby cities.

* However, the same panel then concluded that «the warming trend in global - mean surface temperature observations during the past 20 years is undoubtedly real and is substantially greater than the average rate of warming during the twentieth century.

During a period in which surface warming is stifled by internal variability the rate of energy accumulation would be influenced only by the forcing — there would be no difference between a high - sensitivity model and a zero - feedback model (assuming zero - dimensional models; the reality, with regionally varying temperatures and feedbacks, would be more complex).

For example, atmospheric carbon dioxide grew by approximately 30 % during the transition from the most recent cold glacial period, about 20,000 years ago, to the current warm interglacial period; the corresponding rate of decrease in surface ocean pH, driven by geological processes, was approximately 50 times slower than the current rate driven largely by fossil fuel burning.

In the opinion of the panel, the warming trend in global - mean surface temperature observations during the past 20 years is undoubtedly real and is substantially greater than the average rate of warming during the twentieth century.

The warming of surface temperature that has taken place during the past 20 years is undoubtedly real, and it is at a rate substantially larger than the average warming during the twentieth century.

For example, the rate of warming of surface air temperature observed during the past 20 years is much greater than that observed during the previous 20 - year interval, 1960 — 79, and is not necessarily indicative of the rate of temperature change that will be observed during the future interval 2000 — 2019.

Australia's Bureau of Meteorology says the rate of warming in global surface temperature during the past century has not been uniform, with some decades warming more rapidly than others.

The most widely used metric of global warming — global surface temperatures — indicates that the rate of global warming has slowed drastically and that the duration of the hiatus in global warming is unusual during a period when global surface temperatures are allegedly being warmed from the hypothetical impacts of manmade greenhouse gases.

During the talk, I showed the following graph of the Earth's total heat content, demonstrating that even over the last decade when surface temperature warming has slowed somewhat, the planet continues to build up heat at a rate of 4 Hiroshima bomb detonations worth of heat every second.

Additionally, the direction of heat flow is always only from hot (the ground), to cold (upper atmosphere), Everyone should look at the lapse rate over Antarctica — during the winter (night), the atmosphere is ALWAYS warmer than the surface.
