FUTURE EARTH- CLIMATE OF EARTH (AROUND THE EQUATOR ) 250 MILLION YEARS LATER

The story about the climate at the equator 250 million years ago is both interesting and frightening . Interesting , because it puts all the things we concern ourselves with right now in perspective , and they seem very insignificant , and frightening , because of what it suggests is in store for us . It is believed that 250 million years from now , by a process of `subduction , a giant continent called `Pangea Ultima ' will be formed which will consist of North America and Africa

married to one another with South America rounding off the bottom of the supercontinent . A miniscule ocean basin will remain at the bottom of the two continents

This marriage and other changes will cause a big effect on temperature The huge landmass will mean that winds reaching the land will be denuded of their moisture . Much of what is now southern North America will fall on the Equator . Because it will be robbed of any moisture bearing winds it will probably become barren , and may even form into a desert . The beaches of Miami will probably be replaced by an Arizona like landscape In addition to the geosphere , the water bodies (the hydrosphere ) will also make a big impact on the temperature and climate around the equator . What is today the Indian Ocean will be trapped , creating a giant lake like body the size of modern Australia . Being trapped like a lake , the Indian Ocean will not be...
