Leaked UN draft report warns of urgent need to cut global warming
a reprint from The Guardian, 2018-06-16
The world is on track to exceed 1.5C of warming unless countries rapidly implement “far-reaching” actions to reduce carbon emissions, according to a draft UN report leaked to Reuters.
The final draft report from the UN’s intergovernmental panel on climate change (IPCC) was due for publication in October. It is the guiding scientific document for what countries must do to combat climate change.
Human-induced warming would exceed 1.5C by about 2040 if emissions continued at their present rate, the report found, but countries could keep warming below that level if they made “rapid and far-reaching” changes.
Under the 2015 Paris climate agreement,
almost 200 countries signed up to limit global temperature rises to
well below 2C above pre-industrial levels and to pursue efforts to limit
the temperature increase to 1.5C.
Climate scientist and Climate Analytics director Bill Hare said the draft report showed with greater clarity how much faster countries needed to move towards decarbonisation under various temperature situations and that the impacts of climate change greatly increased between 1.5C and 2C of warming.
Necessary actions include making the transition to renewable energy, powering the transport sector with zero carbon electricity, improving agricultural management and stopping deforestation.
“This IPCC report shows anyone drawing from published papers that there are big differences between 1.5 and 2 degrees warming in both natural and human systems,” Hare said. “Two degrees warming and the tropical reefs have basically no chance – 1.5 degrees, they have a small to modest chance of survival. continue reading...
