NASA has become an over-bloated government bureaucracy in need of a mission, just like most all government bureaucracies, including the military. NASA has spent 20 billion dollars and over 10 years developing their new SLS rocket. It can do 95 tons to low earth orbit (LEO). It can't even do what Saturn V could do back in the 1960's, 140 tons to LEO. SpaceX is developing their Starship which can do 150 tons to LEO and is to be fully reusable. Of course, their first launch was not successful, but they learned a lot. Even their workhorse Falcon 9 rocket had a few problems early on, but now has over 200 successful launches and over 125 successful landings and has the most launches of any rocket in history. Anyway, SpaceX has spent about 6 years and $5 billion of their own mony developing Starship. They have 4-5 under construction at Boca Chica, Texas right now. NASA's SLS cost $4 billion to launch one rocket, and they can only afford to launch it once a year. The Starship costs about $200 million to build one and they can launch multiple times a year because it will be reusable. Next orbital test launch is about 2 months away. Once they work the bugs out, it will make SLS obsolete and wasted tax dollars.
SpaceX is launching Starlink satellites, and brings in about $1.5 billion a year now in profit with Starlink internet systems, and they are still getting new customers worldwide. Anyway all the profit is going into building and making the Starship operational.
I say all this to say, one reason NASA is bloated is they try to have something to do or build in a lot of states and congressional districts. They are not always right. Many countries have said the UN has given the wrong ground temperatures by 1 or 2 degrees to NASA. NASA can't do and read everything. Man does not contribute to the weather changes as much as some people believe. There is also the sun, solar minimum and maximum, solar flares, earth tilt, poles shifting, volcanic eruptions. One volcanic eruption can spew out as much carbon dioxide as all of human activity for a year. During dinosaur times, the earth was much hotter, and wetter. It was more like tropics world wide. Even if the world warmed up some, you can grow crops in higher latitudes than you can now.
I am not against alternative energy if it is cost effective. Lots of solar is available in the Southwest. Lots of wind in the plains. However, not as many people live in the deserts or plains. Power produced here still has to get to where the people live and thus the problem, no transmission lines. Also, no cheap storage of excess solar and wind when it is not being used so the storage can be released when the demand is there.
If you really want to get rid of coal and natural gas, you have to go nuclear power to get the power where the people live. Electric cars have to get cheaper, have longer range, and faster charging times, before they will really take over.
