Dear @Marriott : The Fitness center at your NYC Times Square hotel has TV fixed on “Fox News”— a network that promotes anti-American, pro-Russian propaganda. The manager of the facility says he can’t change the channel, it is set by you. This is deeply offensive.

We still have an ozone layer because we phased OUT (rather than phase DOWN) CFCs. We still hear birdsong in spring because we phased OUT (rather than phase DOWN) DDT. A livable climate requires that we phase OUT rather than phase DOWN fossil fuels.

There are formidable forces aligned against a fossil fuel "phaseout" at the upcoming UN climate talks. Among them, the conference host, the oil-rich UAE, favors a much-vaguer pledge to “phase down” fossil fuels.

200,000 dead from COVID-19. At least 145,000 of those deaths could have been prevented if President Trump had taken decisive action. He did not, and because he did not, he does not deserve a second term.

What starts a wildfire is immaterial to how extensive, damaging & deadly it becomes--that's determined by fuel load (enhanced by climate-driven heat & drought). So when someone cries "arson" as a means of deflection, you know they're a denialist tool. Won't name names though.

It is irresponsible for any media outlet to continue to promote unpaid Trump campaign events masquerading as public health press conferences

I’ve been researching and publishing on #climate for more than two decades, and have written a book about what we need to do over the next decade to avoid a #climatecrisis . I’m excited that it will be published on January 12! #NewClimateWar
