Sentences with phrase «temperature variability decreases»

A study using data taken from fossils and ice cores finds that long - term temperature variability decreased four-fold from the Last Glacial Maximum (LGM) around 21,000 years ago to the start of the Holocene around 11,500 years ago.

Results of both regional climate model simulations and observational analyses suggest that much of the observed rainfall increase — as well as the decrease in temperature and increase in humidity — is attributable to agricultural intensification in the central United States, with natural variability and GHG emissions playing secondary roles.
Averaging smoothes out day - to - day and year - to - year natural weather variability and extremes, removing much of the chaotic behavior, revealing any underlying long term trends in climate, such as a long term increase or decrease in temperature, or long term shifts in precipitation patterns.
Since CO2 isn't the only controller of temperature, internal variability can cause temperatures to decrease over these relatively short periods of time.
There is also a natural variability of the climate system (about a zero reference point) that produces El Nino and La Nina effects arising from changes in ocean circulation patterns that can make the global temperature increase or decrease, over and above the global warming due to CO2.
An increase of daily temperature variability is observed during the period 1977 to 2000 due to an increase in warm extremes, rather than a decrease of cold extremes (Klein Tank et al., 2002; Klein Tank and Können, 2003).
[2] Specifically, an increase / decrease in surface temperature causes a corresponding increase / decrease (not some vague changes, which might be read as variability) in atmospheric CO2.
Those countries not in the tropics, many of them wealthy and highly developed, may see a decrease in temperature variability.
Variability of the El Niño / La Niña cycle, described as a Pacific Decadal Oscillation, largely accounts for the temporary decrease of warming [18], as we discuss further below in conjunction with global temperature simulations.
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.
Hasn't the latest Arctic research (e.g., Kobashi, et al., 2010; Rørvik, et al., 2009) shown that significant variability of high latitude temperatures on > 100 + year timescales have been the natural course of events over the last 1,000 to 1,500 years, all without benefit of increasing or decreasing levels of atmospheric CO2?
Daily temperature variability is actually decreasing, in contrast to CMIP5 simulations and projections.
«Over relatively short, non-climate timescales (less than 20 - 30 years), these patterns of natural variability can lead to all kinds of changes in global and regional near - surface air temperature: flat, increasing, or even decreasing trends,»
In addition to this natural variability, humans have perturbed climate by increasing atmospheric CO2 concentrations, which have increased ocean temperatures, water column stratification, hypoxia, and water column anoxia and have decreased surface ocean pH [6], [7].
If it's a mode of variability that averages to zero in the long run, then it will alternatively increase and decrease the rate of warming and my have little impact on the temperature around the turn of the next century.
