To sum up the same point that everyone in the thread is arguing against one another to make:
1. Global climate change is real
2. Weird weather events have always happened
My points:
1. Yes, weird weather events have always happened, but they are happening more frequently and with more intensity in recent (30 or so) years. Yes, this could be because we are paying more attention or because the media reports it more, but it seems to be that these events are increasingly often.
2. To the people discussing feedbacks: yes there are some negative feedbacks--for one, global climate change could increase temp via the greenhouse effect, which would in turn produce more cloud cover, which would raise the albedo of the planet (more light would be reflected away). On the other hand, there are positive feedbacks--e.g. more glaciers + sea ice melts, and darker surfaces are exposed to the sun; the earth absorbs more heat, and the temperature rises as a result.
However, this is one in a host of factors that even the most up-to-date climate scientists (even you, ckk) are not close to understanding.
Sparknotes; weird stuff is happening more rapidly than ever, and we have no idea what path the climate of the planet will take in the future.
