Experts and researchers are now studying pre historic warm periods to make a model of what is going to happen to Earth if we continue to warm it up.
Experts have chosen three periods: The mid – Pliocene warm era, Marine Isotope Stage 11 and Marine Isotope Stage 5e. Researchers have chosen these three periods as the Earth’s current condition cannot be fully described by just one.
The main point of attention is that, all the past warm periods have result in one final outcome: the increase in sea level by around 6 meter (20 feet). This may come as a surprise as we may read about the sea increasing by just a millimeter each year, but we need to understand, the sea is a vast mass, and so are the ice sheets. So a tiny change continued for years will have an enormous effect.
The recent concern of researchers and environmentalists are for the increase in overall climate temperature, which is about 1 to 2 degree Celsius. This is causing continuous melting of the ice sheets, thus leading to eventual rise in sea level.
Greenhouse gas emission, along with many other reasons, is causing a radical increase in climate temperature which will start to have a serious impact a decade from now. All these are causing ice sheets in the Poles to melts, the snow caps on mountain tops are getting thinner.
All the pre-historic periods have faced catastrophe when a rise of 1 degree Celsius have stayed for more than a thousand years. So researchers are trying to spread awareness among people. Though the model they have created and the outcomes that they have predicted are not the final destination of Mother Earth, but it sure will be if we keep on continuing the way we are now.
The sea level rises by a few millimeters each year. This may sound puny to us when we hear it in the news or read it in the newspaper, but the sea, being vast, needs lots of time to change, so a few millimeters now is an indication to what the future holds if the temperature keeps on rising.
