[From Press Release] In order to limit global temperature rise to 2oC and head off the worst impacts of climate change, global carbon neutrality should be attained by mid-to-late century. This would also keep in check the maximum amount of carbon dioxide (CO2) that can be emitted into the atmosphere while staying within safe temperature limits beyond 2020, says a new report by the UN Environment Programme (UNEP).
Exceeding an estimated budget of just 1,000 gigatonnes of carbon dioxide (GtCO2) would increase the risk of severe, pervasive, and in some cases irreversible climate change impacts.
Released days ahead of the UN Conference on Climate Change in Lima, Peru,UNEP’s Emissions Gap Report 2014 is the fifth in a series that examines whether the pledges made by countries are on track to meet the internationally agreed under 2°C target. It is produced by 38 leading scientists from 22 research groups across 14 countries.
