Nothing to worry about what? About the temperature reaching its upper limit? How about its effect in nature? I don't think its gonna be that easy. Yes, the earth has a way to compensate for it and that might get extreme for humans. You see we are experiencing lots of abnormal phenomenon and global warming might be a part of it. It's not nothing to worry about. It kills people, it damages property. It's must not be taken for granted just because some scientists or reports says it reach its peak.
It always comes down to
now. It's why people drink or smoke or eat. We crave the dopamine hit and want it
now. A less intelligent animal (i.e. mouse) would starve to death in favor of dopamine.
We are asking everyone who has worked hard to
stop wanting more stuff. We are asking billions in third world countries to
not want what we have.
We are asking everyone to deny themselves dopamine, which goes against millions of years of evolution. It's much easier to ask the next generation to do it.
