Global warming

The Climatic Research Unit email controversy (also known as "Climategate") began in November 2009 with the hacking of a server at the Climatic Research Unit (CRU) at the University of East Anglia (UEA) by an external attacker, copying thousands of emails and computer files, the Climatic Research Unit documents, to various internet locations several weeks before the Copenhagen Summit on climate change.

Global warming and climate change are terms for the observed century-scale rise in the average temperature of the Earth's climate system and its related effects.

The Kyoto Protocol is an international treaty which extends the 1992 United Nations Framework Convention on Climate Change (UNFCCC) that commits State Parties to reduce greenhouse gas emissions, based on the premise that (a) global warming exists and (b) human-made CO2 emissions have caused it.

A carbon footprint is historically defined as "the total set of greenhouse gas emissions caused by an [individual, event, organisation, product] expressed as CO2e.

Climate security describes serious threats to the security and prosperity of countries, due to climate warming, and climate actions to adapt and mitigate impacts.

Polar amplification is the phenomenon that any change in the net radiation balance (for example greenhouse intensification) tends to produce a larger change in temperature near the poles than the planetary average.

The global warming controversy concerns the public debate over whether global warming is occurring, how much has occurred in modern times, what has caused it, what its effects will be, whether any action should be taken to curb it, and if so what that action should be.

A general circulation model (GCM) is a type of climate model.

This article is about climate change scenarios.

The complex politics of global warming results from numerous cofactors arising from the global economy's interdependence on carbon dioxide emitting hydrocarbon energy sources and because carbon dioxide is directly implicated in global warming – making global warming a non-traditional environmental challenge.

Climate change feedback is important in the understanding of global warming because feedback processes may amplify or diminish the effect of each climate forcing, and so play an important part in determining the climate sensitivity and future climate state.

This article has not been updated to include results of the IPCC Fifth Assessment Report.

Attribution of recent climate change is the effort to scientifically ascertain mechanisms responsible for recent climate changes on Earth, commonly known as 'global warming'.

A global warming conspiracy theory invokes claims that scientific consensus on global warming is based on conspiracies to produce false data or suppress dissent.
