Climate disinformation back to denying it exists, says UN's Melissa Fleming

People are a lot more worried about climate change than they used to be. And they are also very concerned about disinformation related to climate.

"We're seeing a disturbing spike in disinformation around climate change," Melissa Fleming, the UN's Under-Secretary-General for Global Communications, says during a Global Stage livestream conversation hosted by GZERO in partnership with Microsoft.

But what's more troubling is that the disinformation super-spreaders, she adds, have "returned now to the complete denial narrative" — it's a hoax.


Who's driving it? Advertising investments from fossil fuel companies, which for Fleming is greenwashing we should no longer tolerate.
