Global warming and hurricanes?

There is good evidence that global warming has caused hurricanes to become stronger.

However, the issue is a little tricky because global warming also increases wind shear, which can disrupt hurricanes. So it's possible that they could form less frequently, but that when they do form, they're more intense.

People like to focus on this uncertainty in the relationship between global warming and hurricanes to pretend that the whole man-made global warming theory is uncertain. It's kind of like saying that a doctor can't diagnose any illness because they can't cure AIDS.

Worldwide there's an average of 90 hurricane-force storms per year. That's hurricanes, typhoons etc. and not just in the America's but all over the globe. This number has remained constant, no increase or decrease over time in the average. Therefore it's understood that nothing changes the number of storms. Solar activity causing ocean warming and additional water vapor may lead to more intensive storms some years.

"NOAA attributes this increased activity to natural occurring cycles in tropical climate patterns near the equator. These cycles, called “the tropical multi-decadal signal,” typically last several decades (20 to 30 years or even longer). As a result, the North Atlantic experiences alternating decades long (20 to 30 year periods or even longer) of above normal or below normal hurricane seasons. NOAA research shows that the tropical multi-decadal signal is causing the increased Atlantic hurricane activity since 1995, and is not related to greenhouse warming."

I am sure they have changed their story since the release of this article less than 3 years ago.

Dana, are you really posting an article from your own blog!!! How is that scientific proof? You are an environmental scientist, your company does waste run off analysis. You are trained to believe everything hurts the environment. Your attempts are failing. You might as well have posted your greenhuddler blog.

According to noaa more hit in the 1940s than 1990s. If global warming caused more hurricanes, obviously there should be more in the 1990s. The previous Cat 5s would be hard to assess unless it hit somewhere where it could be measured. If you go down the list, I don't see any increasing trend for Cat 3s. Are you suggesting that Global warming skips the other Cats and goes right to Cat 5. Obviously if AGW increases the number of Cat5 it should increase the Cat 3s as well.

The theologian Leonardo Boff, the founder of Liberation Theology, writes in his Earthcharter Commission essay Sustainable Retreat: " We are comforted by the maxim of the German poet, Hölderin: "When the danger is great, great is also the salvation. "When, within a few years, we reach the heart of the crisis and everything is at risk, then will be apparent the value of our ancestral wisdom and the origins of Christianity: "in case of extreme necessity all becomes common. Capital, knowledge and wealth will be shared by all to save all.  And we will save ourselves, together with the Earth."

first off of those 8 cat 5 hurricanes very few have hit land.. .. now i ask you how do you know 70 years ago there weren't 10??

after all most of the cat 5's die out in the north atlantic... go back 30 years and we would never have known about them..the ones that hit in swampland again.. no one would know it was a cat five fifty years ago...

when comparing how many/what temp etc you have NOW compared to how many we had X years ago... you have to keep in mind the sensitivity of the instruments.
