If NASA and NOAA said “global warming is not a problem” they would immediately lose billions of dollars in funding. No one is going to pay them to study a non-problem.
They have a very fundamental conflict of interest, and they operate as the global warming team, coach, cheerleaders, referee, scorekeeper and press. They also try to prevent neutral third parties from offering an opinion.
It is difficult to imagine a more deeply corrupt situation or conflict of interest. Forty years ago they obtained money by pushing global cooling.
Cooling or warming, it makes no difference to them. It is all about the money.
