NEW YORK: On current trends, humanity would spend the estimated safe budget of Earth-warming greenhouse gases within 20-25 years, the experts said, and urged a quick and dramatic transformation of the energy sector.
“The world is at a critical crossroads,” UN Secretary-General Ban Ki-moon said in a message read to the gathering of nearly 2,000 academics from around the world.
Nations have committed to limiting average global warming to two degrees Celsius (3.6 degrees Fahrenheit) over pre-Industrial Revolution levels, but research suggested the world could be heading for double that or more, he said.
Analysis of emissions curbs pledged by nations to date to underpin the new climate rescue pact, showed the combined effort will “not be sufficient to meet the 2 degree target,” said Ban.
“Clearly strong action still needs to be taken.”
The four-day international science huddle opened Tuesday in the French capital, which will also host a November 30-December 11 UN climate conference for 195 nations to thrash out the long-awaited agreement.
The gathering of academics from nearly 100 countries will review the most up-to-date science on risks and solutions, including technological advances, to feed into the Paris pact.
Scientists stressed the task was a difficult one, but not impossible.
