Try to determine whether this is a hypothesis with solid evidence to back it up, or one that has not yet been supported.

The enviro-whackos blame EVERYTHING on global warming.

Too hot? Global warming.
Too cold? Global warming.
Too wet? Global warming.
Too dry? Global warming.
Hurricanes? Global warming.
Tornadoes? Global warming.
Blizzards? Global warming.
Thunderstorms? Global warming.

That's the beauty of it. No matter what happens it is global warming.

It's very difficult to blame any single event on global warming. There have for example, been floods, droughts, heatwaves etc in the past.

What those studying global warming tend to do is to look at trends and see how big an increase or decrease there have been in weather related events. This is often compared to the number of natural disasters that aren't attributable to global warming - volcanoes, earthquakes etc. The reason for doing this comparison is to iron out anomolies that could occur due to better reporting techniques, closer observation of the planet and the like. In short - it might be true that there's been a 100% increase in the number of floods but if there's also been a 100% increase in the number of earthquakes then it suggests the increase is down to better measuring and awareness of such events.

What we do know is that there has been an increase in average global temperatures, the most pronounced increases occuring in the most recent decades - about 0.7 degrees C rise in the last 50 years, see this graph for more details - http://www.globalwarmingart.com/wiki/Image:Instrumental_Temperature_Record_png

We also know that almost all the hottest years on record have occured in recent years. Off the top of my head I think it's 21 of the hottest years have been in the last 25 years.

There has been an increase in the number of floods (warming causes evapouration which causes rain), there's also been an increase in droughts (warming leads to climate shift resulting in less rain in some places), and there's been an increase in heatwaves - given that recent years have been the hottest on record this is only to be expected.

These three things can clearly be attributed to global warming as all other influencing factors can be taken into account.

In the last 30 years there has also been an 80% increase in the number of category 4 and 5 storms and a 50% increase in their intensity. This can't be solely attributed to global warming as there may be other factors involved. Global warming certainly plays a part but just how much is hard to say.

The scientists who study global warming (and the broader aspects of climatology) are very careful to take everything into consideration before arriving at conclusions. In fact, in science nothing is ever really concluded until it's been rigorously examined and all factors taken into account.

It's worth knowing that global warming isn't new. It was forst speculated in 1811 and has been established fact since 1896. Since that time there has been over 100 years of research and a gathering of immense amounts of evidence from the world over.

I heard that global warming could be a reason of hurricanes occuring.

the hotter summers we've been experiencing, the extreme weather flip flops, droughts, and torrential rains, stronger hurricanes.
