A major international assessment of climate change adopted here by 110 governments provides conclusive new scientific evidence that human activities are causing unprecedented changes in the Earth’s climate.

Produced by the Intergovernmental Panel on Climate Change (IPCC), which was established by the World Meteorological Organization and the United Nations Environment Programme in 1988, the report confirms that it is extremely likely (95-100% probability) that most of the warming since 1950 has been due to human influence.

The IPCC’s previous assessment, released in 2007, described the evidence for human-caused global warming as “unequivocal,” with at least a 9 out of 10 chance of being correct.

The new report further states that greenhouse gas emissions at or above current rates would induce changes in the oceans, ice caps, glaciers, the biosphere, and other components of the climate system. Some of these changes would very likely be unprecedented over decades to thousands of years. Limiting climate change would require substantial and sustained reductions in emissions of carbon dioxide (CO2) and other greenhouse gases.
