SEOUL: The landmark UN report on limiting global warming to 1.5 degrees Celsius was released in South Korea yesterday after a week-long meeting of the 195-nation Intergovernmental Panel on Climate Change (IPCC).

A “Summary for Policymakers” of the 400-page tome underscores how quickly global warming has outstripped humanity´s attempts to tame it, and outlines stark options all requiring a makeover of the world economy for avoiding the worst ravages of climate change.

Here are key findings, grounded in some 6,000 peer-reviewed scientific studies: Capping global warming at 1.5C (2.7 degrees Fahrenheit) above pre-industrial levels will require “rapid, far-reaching and unprecedented changes in all aspects of society”, the IPCC said.

At current levels of greenhouse gas emissions, we could pass the 1.5C marker as early as 2030, and no later than mid-century, the report finds with “high confidence”. To have at least a 50-50 chance of staying under 1.5C without overshooting the mark, the world must, by 2050, become “carbon neutral”. —Agencies
