NEW YORK: US billionaire Michael Bloomberg pledged half a billion dollars on Friday (Jun 7) to fight climate change, saying "our lives and our children's lives depend on it.".
Bloomberg, in a commencement speech at the Massachusetts Institute of Technology (MIT), took aim at climate change sceptics in the Trump administration.
"We will get deeply involved in elections around the country because climate change is now first and foremost a political problem," he said.
"At least for the foreseeable future, winning the battle against climate change will depend less on scientific advancement and more on political activism," Bloomberg told the graduates of the prestigious university.
"Our message to elected officials will be simple: face reality on climate change, or face the music on Election Day.
Bloomberg, who is the UN Secretary-General's climate change envoy, said it was the "the largest-ever coordinated campaign to tackle the climate crisis our country has ever seen.
The UN Intergovernmental Panel for Climate Change warned last October that warming is currently on track towards a catastrophic 3-4 degrees C rise. »
