Under the NASA banner and the heading "Climate Change", the questions are asked and answered with single sentences that are to the point: How Do We Know Climate Change is Real? There is unequivocal evidence that Earth is warming at an unprecedented rate. Human activity is the principal cause. What is causing climate change? Human activities are driving the global warming trend observed since the mid-20th century. What are the effects of climate change? The effects of human-caused global warming are happening now, are irreversible for people alive today, and will worsen as long as humans add greenhouse gases to the atmosphere.

This web page at NASA hasn't been purged yet, as many others have been suspended, according to widespread reports.
It's still clear about facts every human needs to know.
I worked quite a bit for NASA thirty years ago. They were building their "Mission to Planet Earth (MPTE)", later renamed the "Earth Observing System (EOS)". Renamed because, under huge budget pressures, they figured back then it would be harder to scrap "science" than a "mission". I guess that wouldn't be true today.
