From https://www.co2nsensus.com/how-much-money-is-spent-on-climate-change-researchI'm not sure, even if invented by the powers that be, exactly what you think they have to gain by it personally in terms of money and power.
"The 2018 GAO report found that, while the Office of Management and Budget has reported that the federal government spent more than $154 billion on climate-change-related activities since 1993, much of that number is likely not being used to directly address climate change or its risks. Many of the projects reported as “climate-change-related activities” are only secondarily about climate change.'
From my post that was removed
During that time, around the early parts of the Global Warming scare, I was earning a degree in Applied Physics from the North Ave Trade School in Atlanta, Georgia. I had more than a few Professors tell us that we needed to jump on this bandwagon because we'd be able to make a lot of money from it. I wish I had heeded their advice, as they were right.
