Global warming is one of the most dangerous challenges facing all of humanity. Its multiple effects will disrupt everything from the natural habitat to the supply of drinking water and food. And what is even more dangerous, it will lead to some of the most powerful natural disasters ever known to mankind.

In 2004, the Tsunami in Asia showed an act of relentless nature. Less than a year later, on every continent in the United States, Hurricane Katrina struck a blow of equal magnitude. Both disasters caused a massive humanitarian crisis, affecting millions upon thousands of lives. This may not have been directly caused by global warming, but it certainly paints a picture of things to come.

In India, the speed of cyclones in the Andra Pradesh region has jumped from an average of 150 km/h to 250 km/h in just six years. And while some cities risk being wiped out, others risk drying up.

Global warming will make parts of the world very fertile for a period of time, but simultaneously, it will also cause drought in other parts. Scientists have estimated that up to half a million people in Asia could starve to death in the next 30 to 40 years at this rate.

But it’s not just these devastating disasters that hint at what’s happening to our climate. Summers are getting hotter every year, and this winter ski resorts in Central America, Europe, and the United States lost business because it hadn’t snowed like it used to, not even last year! For the first time in over a hundred years, Central Park in New York saw no snow in December 2006.

With global warming, “extreme weather” or “freak weather” is becoming a part of daily life. June and July alone have seen massive flooding in the UK and parts of the US, while in other parts of the US the heat has sparked dangerous bushfires. And this week, the West Coast is expected to hit triple-digit temperatures!

There are few arguments that global warming is real and causes changes in our weather pattern. Every week, scientists find more disturbing and startling evidence to support this fact. And the scientific community is trying everything from simple steps to reduce carbon emissions en masse, to designing colossal artificial air purifiers for Earth. This time, it’s for the good of our planet.
