Reducing emissions of the short - lived climate forcers black carbon and tropospheric ozone — soot and smog — has been identified by scientists as the most effective strategy to slow Arctic warming and melting in the near term, forestalling potentially
irreversible tipping points such as the melting, while the world works to reduce emissions of GHGs.
One by an obscure Professor Emeritus extolls the politicians to act now citing a ten
year irreversible tipping point and that it will take a natural disaster on the scale of Hurricane Katrina for them to act.
This could prevent catastrophic,
irreversible tipping points such as the melting of Arctic sea ice and the Greenland ice sheet, and buy time for implementation of critical strategies to cut long - lived greenhouse gas emissions.
Professor Tim Lenton, from the University of Exeter and one of the authors of the study said: «
Irreversible tipping points are one of the biggest risks we face if we carry on changing the climate.
The fear is that if we exceed either, the climate will pass
an irreversible tipping point.
(This study builds on earlier work challenging assertions that sea ice was poised to pass
some irreversible tipping point.)
Green traditionalists are well - represented among environmental scientists, and they publish high - profile papers warning «that population growth, widespread destruction of natural ecosystems, and climate change may be driving Earth» to
an irreversible tipping point.
