The deniers see no problems on their flat Earth.I stand corrected. For MOST people, it gets rational once we agree on some basic facts. (It is happening, we are causing it, and it will cause significant problems over the long term.)
A few people, like you, prefer to throw sand in the air.
There is a rational discussion to be had. A rational discussion does not include claims like "life is over in 10 years", "nothing is happening", or "standards of living back 200 years". You apparently do not wish to be part of that discussion.
