We know how much ice is on land, people have spent decades drilling the ice and calculating it's volume etc, we know it's melting because there's way less of it now than there was just decades ago and we know how much that melted ice will influence water levels.
We know the effect greenhouse gases have on the atmosphere and global temperatures, people have made scientifically informed charts predicting how the temperature will rise decades ago and we are right on track.
The prediction happened when I was a child, and all my life I've watched the prediction come true. The fact that there's still millions if not billions of people out there who are living through the same situation and still think climate change is a hoax is absolutely baffling to me. Just look at a fucking global average temperature chart for the past few decades holy shit man it's not a secret the planet is cooking. It's not maybe going to cook 500 years from now it's cooking right now and it's getting worse every year how can you possibly look at these simple clear facts and not understand that it's going to continue?
You guys annoy me so much holy shit open your eyes and just look at the world we live in
