Disclaimer: I'm not a climate change denier, I think we should stop burning fossil fuels ASAP.

Though I'm one to question a lot of things and this is my 2 cents. How the hell we know this current changes are completely abnormal? I read about some weird climate anomalies centuries ago and of course there's a lot of evidence that current events are completely abnormal but one question always come to my mind.

What if we're wrong? What if we're being too cooky thinking that by having looked into some evidence that made sense, we're not completely wrong here and current events are just part of a cycle in the planet weather?

Again, I'm questioning but I don't need you guys to present me the proof, I'm aware of it. Just questioning if we're not wrong all along and are here destroying our mental health for nothing. Seems like even by the 1940s standards our generation is being constantly swarmed with problems which we can't fix, which are causing all sort of mental issues due to the complete stress we live in.

This being said, the switch from fossil fuels should be done ASAP, even if we're wrong and it's not causing issues in the environment, they are for sure causing health issues.

There's plenty of easy-to-find evidence out there that shows that the speed and magnitude of these changes are not only unprecedented in human history, but geologic time scales as well. It's also crystal clear that these changes are caused by the massive increase in atmospheric CO2 concentrations caused by humans burning fossil fuels. This is sorted by both theory and massive amounts of evidence. Good primers exist all across the web, http://climate.gov/ is a good starting point.

"But wait, maybe this is all just natural cycles" is borderline willful denial at this point, especially on a well-informed site like HN. Might as well ask if maybe the earth is flat after all.
