Climate Change Question: When did you first learn about climate change??

Any answer may be accepted, but denialism will be fought.
For me, I honestly don't remember.... maybe in 3rd grade???

I became a member of the American Association for the Advancement of Science (AAAS) in the mid-1980s, so have been reading its flagship publication, SCIENCE magazine, every week since then. As one of the premier general science publications (the other is NATURE), it's been publishing research articles on the effects of climate change since as long as I can remember. So, I've been aware of the convergence of multiple fields in science on this topic for a few decades. The deniers are either ignorant (willingly so in many cases) or opportunistic obscurantists with monetary gain or dubious ideology at stake.

In 1992 at the English oral exam of the A-level my topic was the climate summit in Rio de Janeiro. The "greenhouse effect" was cosidered a vital threat.

Environmental Science (EVS) was course taught in my school for first time in 2nd grade. And probably next year there was a chapter on climate so I guess I too came to know about it in 3rd grade.

It was probably the 80s though I had heard of Arrhenius' study prior to that.That may have been an article in the old Science Digest magazine concerning the current interglacial period.

I first read about it in 3rd or 4th grade, probably 4th since my 4th grade teacher had like 2000 books in her classroom library. But it wasn't until October of this year did I finally go into the furthermost depth of this topic, farther than I had gone into any other topic in my whole life. I knew then that I could not contain my feelings about this topic any longer by December 2022. But I knew by then to not take it the way I did in 5th grade... so that's why I'm here.

I remember being a pissed off kid hearing about the USA who didn't ratify the Kyoto protocol. I think that's also the first time I noticed something was on, but I didn't feel it was my job to fix it. I had built an electric car out of LEGO Technics, so I knew it couldn't be that hard. Then I proceeded to act like a buffoon for decades and did absolutely nothing with that knowledge. Still I burn the fossil fuels. I'm a climate Judas like most of you. Thirty pieces of silver so shiny.

Wait you built an electric car out of Legos?? How big was it??

Important questions. I don't remember all of it, but I think I rebuilt a Mindstorms kit into a crude car shape, with two engines, each powering one of the back wheels. It could steer, but it was terrible. It was quick to accelerate and impossible to control. It was capable of transporting the entire battery pack and wired controller, which I deemed a sufficient proof of concept considering there were rechargeable batteries available.

Oh I thought you meant like a life-size Lego electric car...
