Hurricanes like Katrina and Ike a Result of Global Warming?



It's certainly quite likely if not outright definitive that the growing number of extreme weather occurrences, such as the damaging hurricanes Ike and Katrina, is the result of global warming, which is a human-induced and detrimental rising in global temperatures.

Increases in temperature are expected to produce more intense convection over land and a higher frequency of the most severe storms. A report by Hoyos et al. (2006) have linked the increasing trend in the number of category 4 and 5 hurricanes for the period 1970-2004 directly to the trend. Worldwide, the proportion of hurricanes reaching categories 4 or 5, with wind speeds above 56 meters per second, has risen from 20% in the 1970s to 35% in the 1990s.

The change is happening throughout the world, right now. Hurricane Katrina that devastated Louisiana and recently, Hurricane Ike (see photos) in Texas have been examples of this change. In Tanzania, the government reported: "In the past, we had a drought about every 10 years. Now we just don't know when they will come. They are more frequent, but then so are floods. The climate is far less predictable. We might have floods in May or droughts every three years. Upland areas, which were never affected by mosquitoes, now are. Water levels are decreasing every day. The rains come at the wrong time for farmers and it is leading to many problems."

Greg Holland, director of the Mesoscale and Microscale Meteorology Division at the National Center for Atmospheric Research in Boulder, Colorado, said on April 24, 2006, "The hurricanes we are seeing are indeed a direct result of climate change," and that the wind and warmer water conditions that fuel storms when they form in the Caribbean are, "increasingly due to greenhouse gases. There seems to be no other conclusion you can logically draw." Holland said, "The large bulk of the scientific community say what we are seeing now is linked directly to greenhouse gases."

The damaging acts humans are performing are leading to large-scale irreversible and accelerated effects at continental and global scales, which isn't only limited to extreme weather. Other effects include rising sea levels, glacier retreat, Arctic shrinkage, altered patterns of agriculture, an expansion of tropical diseases, changes in the timing of seasonal patterns in ecosystems, and drastic economic impact, just to name a few. In other words, we are causing Earth to age prematurely at a very alarming exponential rate. And if we don't do something about it soon, we're going to experience a harrowing demise, which will ultimately result in the extinction of the human race and the end of the planet as we know it.

I can't understand why there are still some of us who do not believe in global warming when all the evidences and the detrimental results are there for everyone to see and experience.

Conservatives believe that it doesn't matter because Jesus is coming anyway! the end of the world is near, so use all the resources!

i think there is enough evidence to believe the cause and effect of global warming. besides, we can't continue to consume the way we do, what this earth of ours has to offer without harming the invironment, other species and the life of the future generations.
