Sentences with phrase «drive decreases in temperature»

Volcanic events and some types of human - made pollution, both of which inject sunlight - reflecting aerosols (i.e., tiny particles) into the atmosphere, lower temperature and are examples of forcings that drive decreases in temperature.

Not exact matches

«Orbitally driven summer insolation continued to decrease through the 20th century, implying that summer temperatures should have continued to cool,» the researchers wrote this week in the September 4 edition of Science.

Pierre, could you comment on what, exactly, is new in the recent Philipona paper, compared with the two similar papers they published last year («Greenhouse forcing outweighs decreasing solar radiation driving rapid temperature rise over land», «Radiative forcing — measured at Earth's surface — corroborate the increasing greenhouse effect»)?

[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?)

This is a result of a weaker wind - driven ocean circulation, when a large decrease in heat transported to the deep ocean allows the surface ocean to warm quickly, and this in turn raises global surface temperatures.

If you are a car owner and have a thermometer in your car, you may have noticed this, i.e., the temperature generally rises when you drive into an urban area and decreases when you leave an urban area.

We also explore potential channels driving our results and find some evidence that increased temperature variability can lead to a decrease in health care and increased food insecurity during pregnancy.

«And since it has long been known that the DTR has declined significantly over many parts of the world as mean global air temperature has risen over the past several decades (Easterling et al., 1997), it can be appreciated that the global warming with which this DTR decrease is associated (which is driven by the fact that global warming is predominantly caused by an increase in daily minimum temperature) has likely helped to significantly reduce the CHD mortality of the world's elderly people.»

The retreat has been most noticeable at high elevations, driven in large part by warming temperatures contributing directly to melting and indirectly to more precipitation falling as rain rather than snow, in turn increasing the rate at which the glaciers move and increasing the size of glacial lakes, both decreasing ice cover.

The third reason the interior Antarctic data is important is because there is NOTHING on earth that can drive those surface air temperatures down, except a decrease in the energy content of the atmosphere, OR direct radiational heat transfer from the surface to outer space.

The eddy transport mechanism results from a reduction in both the diffusive and advective southward eddy heat transports, driven by decreasing isopycnal slopes and decreasing along - isopycnal temperature gradients on the northern edge of the peak warming.
