'''Global warming''' refers to the increase in the average temperature of the Earth's near-surface air and oceans in recent decades and its projected continuation. Global warming is accepted as the scientific consensus.
* The global average air temperature near the Earth's surface rose 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the last 100 years. The Intergovernmental Panel on Climate Change (IPCC) concludes, "most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations"[http://en.wikipedia.org/wiki/Global_warming#_note-grida7] via the [[Measures to stop global warminggreenhouse effect]].
==Contrarian views==
{{WP|Climate change skeptics}} are a very small and decreasing minority of scientists and a relatively large number of economists. This does not require proving it beyond doubt: consider the practice of the insurance industry to plan for outcomes of varying degrees of likelihood. As the scientific consensus is that there is a very strong probability (the IPCC says 90%{{fact}}) that humans are causing significant climate change, it is vital to prepare for it.
There is less agreement over the best solutions. For example, the role of [[nuclear energy]] and the relative importance of climate change as opposed to directly addressing poverty are open to debate.<ref>{{WP|Bjorn Lomborg}}</ref> Critical analysis of technologies and strategies are important, though of course each side of an argument can have its own bias.  Such contrarian viewpoints and critical analysis can be found at:*[http://www.reason.org/airquality/index.shtml The Reason Foundation] ''Note: this is not an endorsement of arguments found at these websites.
