Sentences with phrase «mean polar temperatures»

Global temperatures of 7C warmer would likely mean polar temperatures were as much as 20C warmer on average.

Not exact matches

Global warming will also mean more forest fires; hurricanes hitting cities that are at present too far north of the equator to be affected by them; tropical diseases spreading beyond their present zones; the extinction of species unable to adapt to warmer temperatures; retreating glaciers and melting polar icecaps; and rising seas inundating coastal areas.

For instance, stratospheric ozone is clearly first order for the southern hemisphere polar vortex strength, but second order (at least) for the global mean temperature.

The rest of the globe does indeed parallel the polar changes closely, but the global mean temperature changes are smaller.

My intuition is that the abnormal warming of the poles will continue, so a 5C rise in global temperature would mean perhaps a 15C rise in polar temperatures, and that should be able to melt Greenland in short order.

Finds that in the Northern Hemisphere there is no reduction in the sensible heat transport despite the reduction in the zonal - mean temperature gradient at low levels associated with polar amplification of the warming

Figure 18: Change in mean summer temperature (as anomalies from the mean), smoothed with a 50 - year filter, and dynamics of the polar tree line.

: Figure 18 - of change in the mean temperature of summer (deviations from the average), smoothed by 50 - year filter, and the dynamics of polar timber line

Northern Ellesmere Island is a polar desert with a mean annual coastal temperature of − 18 °C and annual precipitation of ca. 15 cm.

This waste heat exhibits itself as anomalously high lower tropospheric temperatures in polar and temperate regions — and this raises global mean temperature.

Every Emperor Penguin unable to lay an egg due to unreliable temperature statistics at the British Antarctic Survey means another polar bear drowning due to melting icecaps.

Omission of successively larger polar regions from the global - mean temperature calculations, in both tropospheric and surface data sets, shows that data gaps at high latitudes can not explain the observed differences between the hiatus and the pre-hiatus period....

A forcing of 12 — 16 W m − 2, which would require CO2 to increase by a factor of 8 — 16 times, if the forcing were due only to CO2 change, would raise the global mean temperature by 16 — 24 °C with much larger polar warming.

Kump and David Pollard, senior research associate, Earth and Environmental Systems Institute, looked for another way to create a world where mean annual temperatures in the tropics were above 100 degrees Fahrenheit and polar temperatures were in the 50 - degree Fahrenheit range.
