Yes, I noted this in my commentary for @thebulletin.org a week ago: thebulletin.org/2025/10/you-...
excerpt from linked article: There is no better example than Bill Gates, who just this week redefined the concept of bad timing with the release of a 17-page memo intended to influence the proceedings at the upcoming COP30 international climate summit in Brazil. The memo dismissed the seriousness of the climate crisis just as (quite possibly) the most powerful Atlantic hurricane in human history—climate-fueled Melissa—struck Jamaica with catastrophic impact. The very next day a major new climate report (disclaimer: I was a co-author) entitled “a planet on the brink” was published. The report received far less press coverage than the Gates missive. The legacy media is apparently more interested in the climate musings of an erstwhile PC mogul than a sober assessment by the world’s leading climate scientists.

Hey Bill Gates : Are you familiar with the logical fallacy known as "false dilemma"?

yep: thebulletin.org/2025/10/you-...
excerpt from linked article: Gates became a household name in the 1990s as the Microsoft CEO who delivered the Windows operating system. (I must confess, I was a Mac guy.) Microsoft was notorious for releasing software mired with security vulnerabilities. Critics argued that Gates was prioritizing the premature release of features and profit over security and reliability. His response to the latest worm or virus crashing your PC and compromising your personal data? “Hey, we’ve got a patch for that!” That’s the very same approach Gates has taken with the climate crisis. His venture capital group, Breakthrough Energy Ventures, invests in fossil fuel-based infrastructure (like natural gas with carbon capture and enhanced oil recovery), while Gates downplays the role of clean energy and rapid decarbonization. Instead, he favors hypothetical new energy tech, including “modular nuclear reactors” that couldn’t possibly be scaled up over the time frame in which the world must transition off fossil fuels.

Ironically, I collaborated with several Gates-funded scientists some years ago in a study showing that climate change will potentially expose millions more in the highland regions of Africa to Malaria transmission.

Press release here: www.psu.edu/news/researc...
excerpt from press release: "This is one of the first studies to attempt to explore how climate change might impact conditions at the local level," said Michael Mann, Distinguished Professor of Meteorology, Penn State. "The results suggest the possibility that population centers in cool highland regions could be more vulnerable than previously thought, while other equally large lowland areas might be less vulnerable. But this would have to be confirmed with more detailed modeling assessments that take into account the full suite of environmental and socio-economic factors that ultimately determine risk of malaria."

I was hoping Elon would chime in...
Most troublingly, Gates has peddled a planetary “patch” for the climate crisis. He has financed for-profit schemes to implement geoengineering interventions that involve spraying massive amounts of sulfur dioxide into the stratosphere to block out sunlight and cool the planet. What could possibly go wrong? And hey, if we screw up this planet, we’ll just geoengineer Mars. Right Elon?

That's 7 years old. Thus far direct air capture has been disappointing from a fiscal and practical standpoint. Please read the white paper Joe Romm, a senior fellow of our center (@penncssm.bsky.social) has written on the topic: web.sas.upenn.edu/pcssm/public...
