Environmental Protection Agency. Retrieved 7 August The U. This conclusion is not drawn from any one source of data but is based on multiple lines of evidence, including three worldwide temperature datasets showing nearly identical warming trends as well as numerous other independent indicators of global warming e. Unless otherwise specified, warming is expressed relative to the period —, used as an approximation of pre-industrial temperatures in AR Global warming refers to the upward temperature trend across the entire Earth since the early 20th century Climate change refers to a broad range of global phenomena Climate change may be due to natural internal processes or external forcings such as modulations of the solar cycles, volcanic eruptions and persistent anthropogenic changes in the composition of the atmosphere or in land use.

Deglacial global warming occurred in two main steps from The period from to was likely the warmest year period of the last years in the Northern Hemisphere, where such assessment is possible medium confidence.

Archived from the original on 26 February Archived from the original on 2 September The amount of heat a surface radiates is proportional to the fourth power of its temperature in Kelvin. That finding meshes with climate predictions that dry zones will expand out of the subtropics and push storms towards the poles. The team also found that cloud tops rose higher in the atmosphere by the end of the s, again as predicted for a warming atmosphere.

Eventually, the land and oceans will take up most of the extra carbon dioxide, but as much as 20 percent may remain in the atmosphere for many thousands of years. Archived from the original on 29 March Retrieved 24 February These feedbacks can change the role of the oceans in taking up atmospheric CO 2 making it very difficult to predict how the ocean carbon cycle will operate in the future.
