  1. There      is enough evidence at this point to show that the current climate change      is anything but "natural".
              But for some reason a lot of people like to stick their heads in the      sand and pretend that the colossal amount of pollutants we are pumping      into the atmosphere has no effect at all. After all, even if there was      real damage done, it is unlikely to affect any of us during our lifetimes,      so why should any of us even bother, right?

 

 

First point 1:

The IPCC (Intergovernmental Panel on Climate Change) itself says exactly what I said, there is no evidence of human involvement in climate change today:

 

" (p9) "Projected changes in climate extremes under different emissions scenarios generally do not strongly diverge in the coming two to three decades, but these signals are relatively small compared to natural climate variability over this time frame. Even the sign of projected changes in some climate extremes over this time frame"

On the second point, about 96% of CO2 that gets pumped into the atmosphere doesn't even come from human sources, but comes from nature herself.
