Surface air temperature and its changes over the past 150 years.

When the frozen ground disappears, associated surface air temperatures increase causing increased evaporation of fresh water supplies.

Hansen and his co-author analyzed the surface air temperature at meteorological stations focusing on the years from 1880 to 1985.

The Arctic region"s surface air temperature is projected to warm at a rate about twice as fast as the global average.

Surface air temperatures and sea-surface temperatures are projected to continually increase (very high confidence).

The ELT is generally close to (but not exactly the same as) the long-term annual mean surface air temperature.

Related putative or theoretical concepts include the global-mean surface air temperature, which specifically considers the presence of an atmosphere.

For nearly all models the r.m.s. error in zonal- and annual-mean surface air temperature is small compared with its natural variability.

The monthly mean surface air temperatures, for the Midlands region of England, are given (in degrees Celsius) from the year 1659 to the present.

Only when the surface air temperatures reach -50C (-58F) next October will the planes be able to safely land at South Pole again.

"Greenhouse gases are accumulating in earth's atmosphere as a result of human activities, causing surface air temperatures and subsurface ocean temperatures to rise," the report said.

(The global mean surface air temperature for that period was estimated to be 14 C (57 F), with an uncertainty of several tenths of a degree.)

The land surface air temperature dataset was replaced in 1995 with the newly published CRUTEM1 dataset.

Similar concepts include the global mean temperature, Global radiative equilibrium, global-mean surface air temperature, which includes the effects of Global warming.

The world's average surface air temperature is about 15 C. For information on temperature changes relevant to climate change or Earth's geologic past see: Temperature record.

However, over the Northern Hemisphere land areas where urban heat islands are most apparent, both the trends of lower-tropospheric temperature and surface air temperature show no significant differences.

Patterns of Greenhouse Warming Take-Home Points: The increase of surface air temperatures in response to increasing greenhouse gas levels will not be geographically uniform.

They appeared to be moving along a tunnel carved through an iceberg, and Maitland remembered someone at the base telling him that the surface air temperature was now falling by a full degree per day.

His suggestion made sense as the surface air temperature was much lower than the Bugs use in their tunnels; a camouflaged vent hole should show a plume like a geyser by infrared vision.

More generally, equilibrium climate sensitivity refers to the equilibrium change in surface air temperature following a unit change in radiative forcing (degrees Celsius, per watts per square meter, C/Wm-2).

For observed temperatures, Easterling relied on a data set generated by NOAA's National Climatic Data Center, incorporating globally averaged surface air temperatures from 1901 to 2008.

They judge that global mean surface air temperature has increased by 0.3 to 0.6 C over the last 100 years, broadly consistent with prediction of climate models, but also of the same magnitude as natural climate variability.

HadCRUT3 is the third major revision of this dataset, combining the CRUTEM3 land surface air temperature dataset with the HadSST2 sea surface temperature dataset.

In their analysis the two scientists said the ice retreated at a time when surface air temperatures were highest at Rothera and Faraday, British bases bordering the Bellingshausen Sea on the Antarctic Peninsula.

There has been no regular measurement of surface air temperatures over the Equator at mid-ocean, and nothing like the familiar meteorological records for Central Park or any other official reporting station now exist, Mr. Gadomski said.
