There are several strains of this as Jessica noted. There is a disinformation campaign being run by the Fossil Fuel Interests. There is a "Climate Optimism" campaign being run by by the Techno Optimist wing of Climate Activism. Lastly, there is a "Doomism" is a mental illness meme being advanced among Climate Scientists.

All of them have convergent interests and so have become strange bedfellows.

The Fossil Fuel Interests want to obscure their guilt in what's happening.

The Techno Optimists want everyone to "not panic" and BELIEVE that the Electric Utopia is a hand. As long as we stay focused and at our jobs. The supply chain of PV and EV must not stop.

The Climate Moderate Faction of Climate Scientists, who came to power in the 80's and created the current Climate Paradigm, are defending their life's work. The evidence is accumulating that they are wrong but rather than admit it. They are attacking scientists who question the official paradigm. Saying things like.

Climatologist Michael E Mann: 'Good people fall victim to doomism. I do too sometimes'

Taken together, the overwhelming messaging around Climate Change right now, is "don't worry be happy" things only look bad.
