Today, after several days of record high temperatures (over 30 degrees Celsius), there was a hailstorm in Prague, with chunks of ice over 3 cm in diameter. See short videoclip here and listen to the sound. That wasn't the audio malfunction, you really couldn't hear what someone standing at your side was shouting. It seems perfectly plausible to me that someone could be killed during this.
I doubt Greenpeace & Co. can do anything meaningful to persuade the global industries to stop affecting the global climate (actually, I doubt Greenpeace & Co. can do anything meaningful at all). I also know that the climate changes won't be as quick as Roland Emmerich would like you to believe. But I am pretty sure the weather wasn't fucked up like this 20 or 30 years ago.
Thank God the Czech Republic is in the middle of the Europe and the floods, Tsunami, drought etc. will affect us relatively later than other regions. That means I can probably live the rest of my life rather peacefully before everything goes to hell. I'll let my theoretical children cope with it.
