Why global warming is a real problem

I’m sure you’ve heard enough of this garbage. Blah, global warming, that one thing you learned in school and keep hearing from time to time. Ask yourself, how many times have you taken it seriously? Probably not many.

NASA says the current trend of climate change is significant to note because it is the fastest rate of C02 (carbon di-oxide) emission rate in the last 1300 years. That’s a lot of years. Fortunately for us, in the 21st century we have these amazing things called satellites, ever heard of them? Probably not. You guys most likely spend your time doing weird things like paying your bills and breathing oxygen. Boring life.

No, but seriously, advanced satellite technologies have allowed us to analyse earth like never before. We have satellite data from the last 20-30 years that has made us much more capable of understanding and dealing with the situation.

NASA says,

“The heat-trapping nature of carbon dioxide and other gases was demonstrated in the mid-19th century. Their ability to affect the transfer of infrared energy through the atmosphere is the scientific basis of many instruments flown by NASA. There is no question that increased levels of greenhouse gases must cause the Earth to warm in response.”

Here’s a few compelling pieces of evidence to make you believe.

Sea levels have risen 17 centimetres, or 6.7 inches in the last century. What’s surprising is that the rate of sea level rise in the last ten years is almost double than that of the last century! Put simply, in the last 10 years the rate has increased so much, if you put the last 100 years together, they still wouldn’t match up to what we’re seeing in the last 10.

Global temperature has also risen greatly in the last 10-15 years. Some of the hottest years ever recorded have happened in the last 12 years, and ever since 1970, 20 of the hottest years have been recorded.

Ice sheets have also been melting at alarming rates. NASA states:

“Greenland lost 150 to 250 cubic kilometers (36 to 60 cubic miles) of ice per year between 2002 and 2006.”, “while Antarctica lost about 152 cubic kilometers (36 cubic miles) of ice between 2002 and 2005”.

Judging by this, it is not too difficult to assume that at this speed, humans would be in a lot of trouble in the forthcoming years. Many coastal and island nations/cities are in the danger of flooding or being engulfed completely by water. Polar caps are melting, species are dying off.

Before this planet turns into a graveyard for animals and soon humans, it is time to step up. We better realise the dangers that face us should global warming escalate further. It is high time that we push for renewable technologies and better ways to deal with current issues. Better act before it is too late.
