"Many philanthropists are backing away from climate giving. But one is writing very big checks."

"While many big name philanthropists are backing away from climate giving, at least one megadonor is stepping up and writing major checks.

Michael Bloomberg, the former New York City mayor and founder of Bloomberg L.P., has announced $590 million in new environmental commitments in recent days.

The funds will flow from Bloomberg Philanthropies, his charitable organization, and support work on ocean conservation, energy transition and efforts to combat air pollution.

Some $285 million will go to efforts accelerating the transition away from fossil fuels and toward renewable energy at a moment when the Iran conflict is rattling energy markets."
