The weather is definitely weirder with respect to the relatively stable weather patterns that we've been used to for the past 200 years.
It's the result of global warming. We can debate whether or not humans are responsible for the warming, but the warming itself is a fact supported by empirical evidence. Having said that, all of the climate change models predict more extremes in weather, more drought, more storms, more floods. All of the credible scientists who study this stuff say that we are just seeing the cusp of the changes right now. Once they are in full swing within the next 10 to 30 years, we are going to be in for one hell of a rough ride.
Another thing worth noting is that a natural disaster is not a "disaster" unless people are affected. If a super-typhoon blows harmlessly at sea, who cares? It only becomes a disaster when it hits people who have not prepared or have inadequately prepared for the weather they are likely to experience. Hurricane Andrew was a perfect example of this when it hit South Florida in 1992. Homes that were built in the 30s, 40s, 50s and 60s suffered little or no damage because they were built with hurricanes in mind. Homes that were built in the 80s and 90s got blown to pieces and people died because of the substandard construction.
Doomsday proponents will always seize on things like the weather to support their theories about the end of the world. It has always been thus.....
Cheers to all,
