Sentences with phrase «global average air»

Thus, small changes of global average air temperature are associated with very large changes in some regions, particularly over land, at mid - to high latitudes, in mountain regions.

Global average air temperature near the surface is dominated by the ocean (because it covers two thirds of the planet), particularly at low latitudes.

The recent slowdown in the rise of global average air temperatures during the first decade of the 21st century is being used as a touchstone argument for those who deny the science of global warming.

The primary ways to monitor global average air temperatures are surface based thermometers (since the late 1800s), radiosondes (weather balloons, since about the 1950s), and satellites measuring microwave emissions (since 1979).

Using computer climate models, climatologists have established that the recent trend of an increasing global average air temperature, especially since the mid-20 th century, is unprecedented and unnatural.

For a long time now climatologists have been tracking the global average air temperature as a measure of planetary climate variability and trends, even though this metric reflects just a tiny fraction of Earth's net energy or heat content.

The IPCC last year noted that «Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level.»

Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level (see Figure SPM.3).

As per Intergovermental Panel on Climate Change (IPCC), warming of the climate system is unequivocal, as is now evident from observations of increase in global average air and ocean [continue reading...]

People don't wake up and say «oh gee, that global average air temperature that's gone up by point zero one of degree from last year has really affected my life».

(1) there is established scientific concern over warming of the climate system based upon evidence from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level;

Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global mean sea level

Global average air temperatures have increased relatively slowly since a high point in 1998 caused by the ocean phenomenon El Niño, but observations show that heat is continuing to be trapped in increasing amounts by greenhouse gases, with over 90 % disappearing into the oceans.

It stated for instance, «Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice and rising global average sea level».

It highlighted «increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global mean sea level.»
