From The New York Times (Somini Sengupta):
New climate pledges submitted to the United Nations would reduce greenhouse gas emissions by less than 1 percent, the world body announced.
The global scientific consensus is clear: Emissions of planet-warming gases must be cut by nearly half by 2030 if the world is to have a good shot at averting the worst climate catastrophes.
The global political response has been underwhelming so far.
The head of the United Nations climate agency, Patricia Espinosa, said the figures compiled by her office showed that “current levels of climate ambition are very far from putting us on a pathway that will meet our Paris Agreement goals.”
The figures offer a reality check on the many promises coming from world capitals and company boardrooms that leaders are taking climate change seriously…
Some of the biggest emitter countries — including Australia, Brazil and Russia — submitted new plans for 2030 without increasing their ambitions. Mexico lowered its climate targets, which the Natural Resources Defense Council described as a signal that “Mexico is effectively retreating from its previous leadership on climate and clean energy.”
In contrast, 36 countries — among them Britain, Chile, Kenya, Nepal and the 27 countries of the European Union — raised their climate targets.
The Paris Agreement is designed in such a way that the United Nations can neither dictate nor enforce any country’s climate targets, or what are called nationally determined contributions. Each country is expected to set its own, make regular reports to the world on its progress and set new targets every five years. Diplomatic peer pressure is meant to persuade each country to be more ambitious.
The end goal is to limit global temperature increase to within 1.5 degrees Celsius of 1990 levels. Any warming beyond that, scientists have said in exhaustive studies, would risk widening wildfires and droughts, growing food and water insecurity, and the inundation of coastal cities and small islands.
