is global warming for real? if so, what will happen to earth 100 years hence?

Answer 1

Global warning is real.

Anticipated consequences are quite severe.

Loss of 75% of the world's coral reefs leading to a catastrophic chain of events and a marine extinction on the scale of the Permian-Triassic extinction event (96% of marine species became extinct).

Land based habitat change will cause species migration. In cases where suitable habitat is unreachable extinction will occur. This will accelerate the already high rates of land based extinctions.

Glacial melting and total loss of glaciers in many areas. In particular glaciers may be lost in the Hindu Kush and Himalayas. These glaciers form a principal dry-season water source for China, India, and much of Asia, and therefore some of the most populated areas on earth may run out of water.

Rainfall patters will change causing crop failures in traditional farming areas. North America is especially vulnerable. The impact is multiplied by the fact that groundwater resources are being consumed a much higher than replacement levels and may result in the failure of irrigation in the region.

Destabilization of ocean currents. Excessive fresh water released into the North Atlantic from melting of the Greenland ice sheet could shutdown the thermohaline circulation. Failure of the current would result in North Atlantic and Northern European cooling. Winter temperatures in Europe could fall as much as 40F below current minimum winter temperatures.

Sea level rise of about 3 feet over the next century but continued sea level rise for more than 1000 years. Approximately 200 million people living primarily in Vietnam, Bangladesh, China, India, Thailand, Philippines, Indonesia and Egypt, could be affected. The impact would be spread to other areas due to environmental refugees fleeing flooded cities.

A number of deceases are range limited by temperatures and are expected to spread with increasing global temperatures. Examples include: malaria, hantavirus infection, Crimean-Congo hemorrhagic fever, tularemia, rabies, and vibrio parahaemolyticus gastroenteritis, bluetongue disease.

Financial impacts of increasingly frequent and powerful climatic events have been estimated at $150 billion per year in the next decade alone. 2005 was the most expensive disaster year on record costing $200 billion in weather related events. Tropical cyclone costs are expected to increase five fold by 2080 if global warming is not checked.

Answer 2

Global warming is a threat to man kind as it would turn out to be hazardous to man kind if not curbed within a reasonable period. The air conditioner and refrigerator that we use in our daily home gives out chlorofluorocarbons which are extremely harmful the ozone layer and there are SO many more facts if these all continues human life will be tougher.

Answer 3

I see 2 possibilites :

possibility 1 : we get lucky, and in 100 years, there won't be any more oil to burn (or so expensive we won't burn it anymore), and the climate will get back to where it ought to be

possibility 2 : we don't get lucky, and before 100 years, it gets so hot that all the ice in the poles melt... this will affect the golf stream, slow it down enough to put us through an ice age. (enjoy the heat while you still can)

Answer 4

yes it is real and no it's not bad...

the earth has been on a cycle of warming and cooling just like every other planet in the universe... it's cycle goes into phase which may verywell be bad for mankind, but for earth in general I think she can handle anything we throw at her...

personally I believe there is nothing that mankind could do to totally destroy earth... just destroy our environment in it. I think she would recover from anything we could do. then she would create a different group of species to roam it...

Answer 5

Yes, it is real, but we don't know its reason. (Natural, pollution, both or none?)

What can happen is quite unpredictable without knowing how long will it take and how much will it get warmer.The climate can change, sea levels rise, rich areas turns into deserts, species extinct... etc. But we will survive, don't worry about that; it's just that life will be harder.

Answer 6

It will be without mammals
