But all the doomsayers claim to know that all the climate change is human caused. It's just speculation from those who want us to be responsible for destroying our planet so they can control people into doing what THEY think we should be doing. Too many unknowns and too many problems in the man caused change ideas. Yep the climate is changing.
Many scientists think it's natural. A great many are willing to admit we don't really have enough data to say what the cause is.
