What irritates me, is the people who are most certain they know for sure what the outcome is are the most pessimistic.
It's all over sites like Reddit too. I see so many comments on there, similar to, but sometimes worse, as wetcardboard's prediction that we WILL reduce the planet to a desert and this will be within 100-150 years... oh no sorry it's not just a prediction is it? It's categorical fact apparently (capital letters and all). I can't actually find any decent evidence online to support that prediction, and the Reddit comments are usually speculation based too - a lot of the people saying we have a decent chance of rescuing emissions and developing technology to protect communities are the only people who link to any evidence on there or (say they have) an environmental science background. Even if I could find evidence to suggest that outcome, I wouldn't go around stating it as fact.
This thread is a bit like aomeone saying they have cancer and then being told, in no uncertain terms, by a lay person, that they will die next week and it will be excruciatingly painful.
Likewise with madness, "it is surely inevitable". I'm not saying either of you have no reason to predict these outcomes, I'm just interested to note that the people with the most negative views seem to be the most sure of themselves when, actually, nothing is certain about the future. And, if you have any sort of compassion and you truly believe we are completely fucked regardless, then why on earth are you bothering to say so? If you have completely given up, based on hard evidence, then surely you're better off enjoying what life you have left and being done with it?
