Current Paris climate pledges ‘won’t limit global warming to 2C’

“Pledges made by countries ahead of the Paris UN Conference in December are not sufficient to limit global warming to 2°C, according to analysis published today (19 August) by the Grantham Research Institute on Climate Change.

“The US is expected to offer emissions cuts of 26 to 28% by 2025, the EU has agreed to cut its emissions by 40% by 2030, compared with 1990 levels, while China has promised its emissions will peak by 2030.

“However the analysis concludes that the intended national determined contributions (INDCs) that have been submitted by 46 countries would lead to annual global emissions in 2030 of 56.9 to 59.1bn tonnes of carbon dioxide equivalent.

“At most this is 12bn tonnes more than the level UNEP says would give the planet a 50-66% chance of limiting global warming to less than 2°C.”  Sourced through Scoop.it from: www.edie.net

GR:  The two-degree goal does not provide a safety margin.  As we learn more about our climate systems and how they are reacting to warming, the prudent course is to cut emissions by 50% by 2025 and 90% by 2030.  It’s like a war; if you ease your way in, you loose.
