You're on Y Combinator, not Facebook.

It's not a conversation when you can educate yourself with literally any Google query on the topic. Your fingers aren't broken and your Internet works, so use the tools available to you. Try "climate change faq", "common climate change misconceptions", "evidence for anthropogenic climate change", etc, etc...

Once you've read the top 10 results for each of those, come back and then we can have a conversation instead of an argument born out of wilful ignorance.
