WOTC - Climate change

I asked this question in the Wisdom of the Crowd:

What causes the severe storms in recent years?

Here are the responses: (46 Votes)

59 % - They are more severe due to "climate change" caused by destruction of the ozone layer.
22 % - They are normal storms but cause more damage due to developments.
13 % - They appear severe due to more reporting through the media.
7 % - In past centuries, we also had similar severe storms.
