Due to Global Warming And Climate Changes


How to recognize global warming
Whether or not it's brewing something good or something bad, Nature always tries to warn us through many signs. The slow process involved in global warming results in many different things and some of its signs include:

Melting of glaciers
Most of the mountain glaciers on our planet that have been monitored for the past 150 years are reportedly shrinking. The glaciers most affected by global warming those located in the lower latitudes and many of them are disappearing. If glaciers continue to shrink, it could affect water supply in areas that depend heavily upon mountain watersheds.

If the scenarios of global warming continue, most of the glaciers that still stand today will disappear by 2100.

Ocean warming
Sea level increase is attributed to warmer temperatures, which in turn result to the melting of ice glaciers. Over the last 100 years, sea level has increased from 10 cm to 25 cm. Projections over the next hundred years indicate that sea level will rise higher, from about 15 cm to 90 cm. Based on the higher figure, that's about 3 feet.

Translated, this could mean that beaches lose about 50 feet of area for every foot of increase in sea level. Some islands may even disappear beneath sea water completely.

Heat waves
Heat waves and periods of weather that are unusually warm are also signs of global warming. These may come about with varying degrees of their severity and frequency, causing concerns in the economics and health on a global scale.

How global warming brings climate change and what it means to us
The earth's climate has always been changing, although not at an abrupt rate. There had been periods of warming and cooling in the earth's 4.65 billion-year history. Strange as it may sound to some, this is the reason why life became possible on this planet millions of years ago. Unfortunately, not all of the changes in climate brought about by global warming may be beneficial to many of us.
