What is Global Warming?

Summary/title:-
Hey! I just realized that many people have no idea or have never heard of Global Warming. I have this article for you guys, its not that long so please read the whole thing and comment.




Global Warming is defined as the increase of the average temperature on Earth. As the Earth is getting hotter, disasters like hurricanes, droughts and floods are getting more frequent.
 
Over the last 100 years, the average temperature of the air near the Earth´s surface has risen a little less than 1° Celsius .It does not seem that much but It is responsible for the conspicuous increase in storms, floods and raging forest fires we have seen in the last ten years, though, say scientists.

Their data show that an increase of one degree Celsius makes the Earth warmer now than it has been for at least a thousand years. Out of the 20 warmest years on record, 19 have occurred since 1980. The three hottest years ever observed have all occurred in the last ten years.

But it is not only about how much the Earth is warming, it is also about how fast it is warming. There have always been natural climate changes – Ice Ages and the warm intermediate times between them – but those evolved over periods of 50,000 to 100,000 years.

A temperature rise as fast as the one we have seen over the last 30 years has never happened before, as far as scientists can ascertain. Moreover, normally the Earth should now be in a cool-down-period, according to natural effects like solar cycles and volcano activity, not in a heating-up phase.

Climate change won’t be a smooth transition to a warmer world. The world will be especially affected by abrupt changes.
