you need to do some reading the recent storm Sandy was made more intense because of cold air laminating into the swirl not warm air the system in the pacific are totally different world temperature fluctuations are driven by heat being released into the oceans because of spin of the earth the tidal pull of sun and moon and pressure from continents the greater the ice on the Antarctic the more unstable earth climate. because of pressure causing heat to be released along tectonic plates go look at a Globe then see for your self why it may be influenced by natural forces sun moon and earth spinning the ice sitting on the Antarctic pushes the continent into the crust there has been a 1% increase in ice there for thirty years, ths exaplins certain earth quakes possibl the boxing day tsunami in 2004 the greater the difference between cold air and warm water the more intense the cylone cooling will make cyclones bigger warming will reduce them .
these are different events.
while the USA had its warmest temps in 2012, tornado numbers were down.
Hurricanes require warm ocean temperatures. The higher temperatures provide more energy, but not necessarily a higher number of hurricanes.
They are not driven by more warming, they are driven by temperature differences, and extreme weather is actually low in the last decades, less tornadoes less hurricanes. but lots of extreme media reporting (never mind that it's not true it sells news).
They are caused by extreme differences in temperatures. A warmer atmosphere decreases the intensity and frequency of all of the above. The claim of more intense storms with Global Warming is one of the biggest fallacies and is made to alarm people.
They are driven by temperature differences.
