This is not what I said, so I'm going to explain this critical point before this runs out of control.
Most people in the world do not know what the SCIENTIFIC METHOD is and think that "scientists" are simply people who wear lab coats, play with chemicals, rocket ships, can explain complex stuff about the natural world, make crystals crawl up a glass, etc. In reality, a scientist is someone who practices the scientific method in a given field and continually checks and rechecks theirs and others works to come to their conclusions. In this case, it's climate science and reputable institutions known for following the scientific method are raising the alarm.
We need to be cautious, though, always cautious, because as Parson wrote, revolutions in understanding do occur and that is the only way we are sure of the facts. We need to trust the conclusions of a climate science institution not because we see it researches the climate, but because we know they are using the scientific method to come to those conclusions.
Trust in the scientific method first, then the scientists who we know are applying it. It has and does occur that politics, corporate, and, yes, personal greed taint scientific studies that go on to form the basis for public policies and culture attitudes. I am not saying this is the case for reputable climate change science institutions.
