Sentences with phrase «increased global humidity»

Not exact matches

When researchers ran the numbers for the Corn Belt, the global models fell short of reality: They predicted both temperature and humidity to increase slightly, and rainfall to increase by up to 4 % — none of which matches the observed changes.

Now, however, increasing humidity in Chile, possibly caused by global climate change, has started to turn some mummies into black ooze (pictured).

Total column water vapour has increased over the global oceans by 1.2 ± 0.3 % per decade from 1988 to 2004, consistent in pattern and amount with changes in SST and a fairly constant relative humidity.

In the central United States, for example, observational data indicate that rainfall increased, surface air temperature decreased, and surface humidity increased during the summer over the course of the 20th century concurrently with increases in both agricultural production and global GHG emissions.

Global temperatures have increased by ∼ 0.2 °C per decade over the last three decades16, possibly leading to an acceleration of the global water cycle with more intense rainfall events17, more severe and widespread droughts18 (despite drought frequencies appearing unchanged19) and regional humidity variatiGlobal temperatures have increased by ∼ 0.2 °C per decade over the last three decades16, possibly leading to an acceleration of the global water cycle with more intense rainfall events17, more severe and widespread droughts18 (despite drought frequencies appearing unchanged19) and regional humidity variatiglobal water cycle with more intense rainfall events17, more severe and widespread droughts18 (despite drought frequencies appearing unchanged19) and regional humidity variations20.

Therefore a statistic that combines average global temperature, global humidity, and the negative of ice cover should increase every year.

Yes, global warming increases absolute humidity so more extreme weather incidents are expected — as in more downpours and fewer drizzles.

re Gavin @ 223 I know what the mean global temperature is (actually, I don't, see below) but the question was why is this a meaningful metric for looking at changes over time, when you could get the same global mean from very different distributions of temperature (eg increase the poles, decrease the tropics) which would have very different interpretations of energy balance (at least if I am right that humidity matters)?

Global climate change risks are high to very high with global mean temperature increase of 4 °C or more above preindustrial levels in all reasons for concern (Assessment Box SPM.1), and include severe and widespread impacts on unique and threatened systems, substantial species extinction, large risks to global and regional food security, and the combination of high temperature and humidity compromising normal human activities, including growing food or working outdoors in some areas for parts of the year (high confidGlobal climate change risks are high to very high with global mean temperature increase of 4 °C or more above preindustrial levels in all reasons for concern (Assessment Box SPM.1), and include severe and widespread impacts on unique and threatened systems, substantial species extinction, large risks to global and regional food security, and the combination of high temperature and humidity compromising normal human activities, including growing food or working outdoors in some areas for parts of the year (high confidglobal mean temperature increase of 4 °C or more above preindustrial levels in all reasons for concern (Assessment Box SPM.1), and include severe and widespread impacts on unique and threatened systems, substantial species extinction, large risks to global and regional food security, and the combination of high temperature and humidity compromising normal human activities, including growing food or working outdoors in some areas for parts of the year (high confidglobal and regional food security, and the combination of high temperature and humidity compromising normal human activities, including growing food or working outdoors in some areas for parts of the year (high confidence).

We expect, through the Clausius - Clapeyron equation, that the specific humidity will increase roughly 20 % in response to 3 degrees of warming provided the temperature and humidity vary in such a way as to keep the global relative humidity roughly constant.

Global rainfall increases typically cause an overall reduction of specific humidity (q) and relative humidity (RH) in the upper tropospheric levels of the broader scale surrounding convection subsidence regions.

However, the available data now show evidence for global increases in upper - tropospheric specific humidity over the past two decades (Figure TS.8).

When researchers ran the numbers for the Corn Belt, the global models fell short of reality: They predicted both temperature and humidity to increase slightly, and rainfall to increase by up to 4 % — none of which matches the observed changes.

This snowpack accumulation near the poles, which gets its water via the Arctic and Antarctic oceans, that in turn rob it from equatorial latitudes of our oceans, also results in a reduction in the earth's spin axis moment of inertia and causes the spin rate to increase as evidenced in the recent history of the rate at which Leap Seconds are added to our calendar (see Wysmuller's Toucan Equation for more on this evidence that during this warm time with much greater polar humidity, earlier seasonal, later seasonal and heavier snows are beginning to move water vapor from the oceans to the poles to re-build the polar ice caps and lead us into a global cooling, while man - made CO2 continues to increase http://www.colderside.com/faq.htm).

Another paper discusses how atmospheric humidity increased during the recent period of pronounced global warming (from about the late 1970s to the present), with a humidity decrease during the cooling / temperature stagnation period of ~ 1940s to the 1970s:

A slight change of ocean temperature (after a delay caused by the high specific heat of water, the annual mixing of thermocline waters with deeper waters in storms) ensures that rising CO2 reduces infrared absorbing H2O vapour while slightly increasing cloud cover (thus Earth's albedo), as evidenced by the fact that the NOAA data from 1948 - 2008 shows a fall in global humidity (not the positive feedback rise presumed by NASA's models!)

And these results, as they continue, «suggest that an increased temperature will result n a shortening of the life span of mosquitoes (due to decreasing humidity) and decrease in the capacity of larva production and maturation (due to decreasing rainfall),» so that ultimately «the increase in temperature will not result in an increased malaria transmission in Burundi,»...» [Hermenegilde Nkurunziza and Juergen Pilz 2011: International Journal of Global Warming]

«Working with data pertaining to 7450 cardiovascular - related deaths that occurred within Budapest, Hungary, between 1995 and 2004 — where the deceased were «medico - legally autopsied» — Toro et al. looked for potential relationships between daily maximum, minimum and mean temperature, air humidity, air pressure, wind speed, global radiation and daily numbers of the heart - related deaths... scientists report and restate their primary finding numerous times throughout their paper, writing that (1) «both the maximum and the minimum daily temperatures tend to be lower when more death cases occur in a day,» (2) «on the days with four or more death cases, the daily maximum and minimum temperatures tend to be lower than on days without any cardiovascular death events,» (3) «the largest frequency of cardiovascular death cases was detected in cold and cooling weather conditions,» (4) «we found a significant negative relationship between temperature and cardiovascular mortality,» (5) «the analysis of 6 - hour change of air pressure suggests that more acute or chronic vascular death cases occur during increasing air pressure conditions (implying cold weather fronts),» (6) «we found a high frequency of cardiovascular death in cold weather,» (7) «a significant negative relationship was detected between daily maximum [and] minimum temperature [s] and the number of sudden cardiovascular death cases,» and (8) «a significant negative correlation was detected between daily mean temperature and cardiovascular mortality.»

At the high - end scenario of global warming, in which global average temperatures increase to 8.46 degrees Fahrenheit above 1986 - 2005 average levels by 2100, the report found that «the combination of high temperature and humidity in some areas for parts of the year is projected to compromise normal human activities, including growing food or working outdoors.»

One study, published in today's edition of the journal Nature, found that the overall increase in worldwide surface humidity from 1973 - 99 was 2.2 %, which is due «primarily to human - caused global warming,» according to study co-author Nathan Gillett of the University of East Anglia, in Norwich, U.K.
