Scientists to probe ways of meeting tough global warming goal

Scientists on Thursday set the outlines of a report on how to restrict global warming to a limit agreed last year by world leaders - even though the temperature threshold is at risk of being breached already.

The U.N.-led study, due to be published in 2018 as a guide for governments, will look into ways of cutting greenhouse gas emissions to cap the rise at 1.5 degrees Celsius (2.7 Fahrenheit) above pre-industrial levels.

It will examine impacts of a 1.5C rise on vulnerable parts of the world including Greenland's ice sheet and coral reefs.

Thelma Krug, a Brazilian scientist who led the four-day meeting in Geneva, said it will also cast the fight against climate change as part of a wider struggle to end poverty and ensure sustainable growth.

"Rapid changes are needed for (no rise above) 1.5C," she told Reuters.

World leaders agreed to work towards that target at a meeting in Paris in December, also requesting the report as part of a global agreement to phase out greenhouse gas emissions, mainly from burning fossil fuels, in the second half the century.

The global rise reached 1.3C in the first half of 2016, which is almost certain to be the warmest year since records began in the 19th century, beating 2015.
