Today Is...Typhoon Haiyan Hits Philippines

I once got pulled up for calling a mid-latitude storm a hurricane because hurricanes develop in a different part of the Atlantic but it is pretty safe to call what was that hit the Philippines today in 2013 a Typhoon because all the headlines at the time were screaming: 'Catastrophic damage to be caused by Typhoon Haiyan'.
The fastest speed at which the tropical cyclones (Hurricanes and Typhoons) can blow naturally on Earth is around 235 miles per hour (378 kilometers per hour) and Haiyan was measured at sustained winds of 195 mph, with gusts up of to 235 mph which makes it the strongest tropical cyclone ever recorded at landfall and a storm which reached the theoretical maximum naturally occuring wind possible.
The Super-Typhoon left at least 7,000 people dead and caused billions of pounds worth of damage and was a powerful reminder of the Earth's natural power and the extreme weather events becoming more frequent and intense.
The thing with Climate Change is that it doesn't mean there will be more Typhoons and Hurricanes, it just takes the weather that is already there and ramps it up to 10 or in the case of tropical storms, takes it to Category 5.
As is quite wrongly sometimes said, Climate Change is not making the tropical cyclones but it is creating the perfect conditions for them to thrive when they do arrive due to higher water temperatures, warmer air holding more moisture and rising sea levels which increase storm surge and flooding.
The intensity of tropical cyclones, measured by their lowest central pressure, has five of the top 10 coming in the last two decades and tropical cyclones have been developing faster due to the warming Ocean's, rising from a Tropical Storm through the wind scale quicker.
Another consequence is due to the increasing warmth of the ocean and air, tropical cyclones are slower moving so, the National Oceanic and Atmospheric Administration (NOAA) found that they are 10% slower today and linger longer so they dump more rain over a certain area instead of moving on quickly.
As the climate continues to change, Ocean temperatures will continue to rise and the warmer the water the stronger the tropical cyclones become resulting in more rain, flooding and wind damage so Climate Change won't create more Typhoons and Hurricanes, but it will make the ones that we do have more powerful and we are seeing that today and scarily, we are only at the start of the big, dramatic climate changes.
