Sentences with phrase «largest temperature decreases»

Not exact matches

In cooler areas, the less intense warming and large decrease in cold - related deaths may mean no net change or a marginal reduction in temperature - related deaths.

While the overlap during deglaciations is large (which makes it near impossible to make any estimates of relative forcings), during the start of the last ice age, there was no overlap: CO2 started to decrease (some 40 - 50 ppmv) when the temperature was already near it's minimum.

What's more, the haze has masked the effects of global warming across large parts of China, particularly in the central and eastern regions, where daily high temperatures have actually been decreasing.

[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?)

It could be smaller than that or larger, depending on the way that temperature varies with height; but it will not be larger than twice that, provided that a temporary saturation doesn't happen and then significantly reverse in the span of a single doubling — in other words, provided that the process of any temporary saturation and following reversal (wherein BTc0 increases, halts, and then decreases, or in the opposite order) can be sufficiently resolved by the fractional change in CO2.

While the overlap during deglaciations is large (which makes it near impossible to make any estimates of relative forcings), during the start of the last ice age, there was no overlap: CO2 started to decrease (some 40 - 50 ppmv) when the temperature was already near it's minimum.

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.

In my opinion, such a change notice should have reported the 0.15 deg C decrease in post-2000 US temperatures, noted the change in rankings since that was a source of discussion that year, alerted users of the data base that changes at individual stations might be much larger than that (and in either direction).

The mass balance and d13C balance shows that vegetation as sink is not large enough to absorb all human CO2 if the oceans are a source and ice cores show that CO2 and temperature go to a (surprisingly linear) new equilibrium for every change in temperature level, not a sustained increase or decrease.

So we should welcome gradual warming and fear large decreases in global temperatures.

In commenting on their findings, the three researchers write that «the large number of stable glacier termini and glacier advances is influenced by positive glacier mass balances in the central Karakoram during the last decade,» citing Gardelle et al. (2012, 2013) and Kaab et al. (2012), which they indicate is «induced by increasing winter precipitation and decreasing summer temperatures since the 1960s,» citing Archer and Fowler (2004), Williams and Ferrigno (2010), Bolch et al. (2012), Yao et al. (2012) and Bocchiola and Diolaiuti (2013).

In addition to the very large carbon dioxide offset, the researchers calculated a potential decrease in temperature of about 0.07 °C

This increased demand for cooling by the middle of this century is projected to exceed 10 gigawatts (equivalent to at least five large conventional power plants), requiring more than $ 6 billion in infrastructure investments.72 Further, approximately 95 % of the electrical generating infrastructure in the Midwest is susceptible to decreased efficiency due to higher temperatures.72

According to the model, temperatures in the North Atlantic and Greenland showed the largest decrease, with slightly less cooling over parts of North America and Europe.

Even in areas where precipitation does not decrease, these increases in surface evaporation and loss of water from plants lead to more rapid drying of soils if the effects of higher temperatures are not offset by other changes (such as reduced wind speed or increased humidity).5 As soil dries out, a larger proportion of the incoming heat from the sun goes into heating the soil and adjacent air rather than evaporating its moisture, resulting in hotter summers under drier climatic conditions.6

One thing that annoys me a lot about normal reconstruction of temperature, they tend to conclude to a large decrease in diurnal temperature range.

The flat or decreasing decadal temperature outcome is not unprecedented, neither in the much - longer timespan periods of large overall global temperature rise we see historically nor in the GCMs.

While the overall sea ice extent in the Southern Ocean has not changed markedly in recent decades, there have been increases in oceanic temperatures and large regional decreases in winter sea ice extent and duration in the western Antarctic Peninsula region of West Antarctica and the islands of the Scotia Arc.

If you look at the average global response to large volcanic eruptions, from Krakatoa to Pinatubo, you would see that the global temperature decreased by only about 0.1 °C while the hypersensitive climate models give 0.3 to 0.5 °C, not seen in reality.

«From 1910 - 1949 (pre-agricultural development, pre-DEV) to 1970 - 2009 (full agricultural development, full - DEV), the central United States experienced large - scale increases in rainfall of up to 35 % and decreases in surface air temperature of up to 1 °C during the boreal summer months of July and August... which conflicts with expectations from climate change projections for the end of the 21st century (i.e., warming and decreasing rainfall)(Melillo et al., 2014).»

Hence, decreases in relative humidity occur at stations experiencing the largest temperature increases in winter and spring as shown in Fig. 7.

(With increasing altitude the pressure drops and that makes the density go down, but the temperature drops also and that has the opposite effect making the decrease in density with altitude the weaker the larger the lapse rate is.)

Scientific confidence of the occurrence of climate change include, for example, that over at least the last 50 years there have been increases in the atmospheric concentration of CO2; increased nitrogen and soot (black carbon) deposition; changes in the surface heat and moisture fluxes over land; increases in lower tropospheric and upper ocean temperatures and ocean heat content; the elevation of sea level; and a large decrease in summer Arctic sea ice coverage and a modest increase in Antarctic sea ice coverage.

But even if the rest of the month is not quite cold enough to push the entire year into negative territory, the 2013 annual temperate will still be markedly colder than last year's record high, and will be the largest year - over-year decrease in the annual temperature on record, underscoring the «outlier» nature of the 2012 temperatures.

It is one stage within a large climate pattern known the El Niño - Southern Oscillation, or ENSO, that increases and decreases the temperatures in the Pacific Ocean in somewhat predictable cycles, thereby affecting climate worldwide.

So, if you have a large enough influx of cold water from the deep ocean, it can cause the global temperature to decrease temporarily, even while the greenhouse component is acting to push the global temperature to be warmer.

Furthermore, the earth's surface will become much more ice - and snow - covered leading to a larger albedo and hence a further temperature decrease.

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.

For JJA (figure 4b), Central America, parts of Brazil, southern Africa, and parts of Europe, northern Africa and the adjacent part of Central Asia are projected to suffer large rises in temperature and decreased precipitation.

Similarly, if global temperatures drop for some reason (for example, a large volcanic eruption dumping massive amounts of aerosols into the air), we should expect to see water vapor concentrations decrease.

Increased temperature will increase the absolute humidity according to the Clausius - Claperyon equation; a larger amount of water vapor will decrease the density of air, all else being equal, which will increase convection and the relative amount of adiabatic versus radiative cooling.

To claim that the global avg temp might as well have decreased 0.7 degrees as increased 0.7 degrees since preindustrial times flies in the face of basic physics, namely that the planetary temperature is governed (a.o.) by the planetary energy balance, and that this balance has substantially changed over the past 100 or so years due in large part to anthropogenic climate forcings, with a bit of help from natural climate forcings.
