What affect might global warming have on earth's inhabitants?
Answer:
To answer your question, one has to assume global warming exists in the sense that the left wing celebrities want you to believe it exists. In the 1970's scientists were up in arms over the coming ice age and global cooling that was going to wipe out planet earth, and its inhabitants. That was 30 years ago. Now we have junk science and people like Leo dicaprio, Sheryl Crow and Al Gore, neither of them have any scientific training at all, telling us that the earth is in danger. From what exactly? Its own weather cycles that have existed for millions of years? We are very ignorant if we think we can affect the earth by driving hybrids and using less toilet paper. The earth controls it self, like it always has. Carbon dioxode is absorbed by the earths vegetation and does not adversely affect our weather.
The tempatures may be slightly going up, but not because of anythign humans have done, but because of what the earth has always done
With global warming on the increase and species and their habitats on the decrease, chances for ecosystems to adapt naturally are diminishing. This has already had numerous affects on earths inhabitants:
* Caused the droughts in Ethiopia in the 1970s and 80s where millions died, because the northern hemisphere oceans were not warm enough to allow rain formation.
* Lead to the European heat wave in 2003, which saw thousands of people die.
* The 1997 Niño caused huge problems all over the world, from droughts to floods and poor yield of crops. It is thought that there is a link between climate change and the severity of Niño.
*Even small changes in temperature are enough to send hundreds if not thousands of already struggling species into extinction.
* The key impact of global warming on wildlife is habitat displacement, whereby ecosystems that animals have spent millions of years adapting to shift quickly.
* Warmer spring temperatures could dry up critical breeding habitat for waterfowl in the prairie pothole region, a stretch of land between northern Iowa and central Alberta.
* Wildlife populations can sometimes move into new spaces and continue to thrive. But concurrent human population growth means that many land areas that might be suitable for such “refugee wildlife” are already taken and cluttered with residential and industrial development.
* Many birds have altered the timing of long-held migratory and reproductive routines to better sync up with a warming climate. And some hibernating animals are ending their slumbers earlier each year, perhaps due to warmer spring temperatures.
* A World Wildlife Fund study found that a northern exodus from the United States to Canada by some types of warblers led to a spread of mountain pine beetles that destroy economically productive balsam fir trees. Similarly, a northward migration of caterpillars in the Netherlands has eroded some forests there.
It will kill us all. Eventually. Duh.
Rising food prices,shortage of water,both hotter and colder weather,
Ultimately,Famine,Wars and death
in North Africa,India,Mexico ,millions of people are effected by land loss and desertification and some have died as a result of heat waves ,as in France 2 years ago
,the Sahara is growing by 7 kilometers a year
and most of the desserts we know are a results of mans actions ,and they are increasing
collectively this planet is drying up ,
each degree rise in temperature means 10%crop loss
and there is less and less water (because of deforestation) and the overpumping of carbon and surface aquifers ,and more and more agriculture requires irrigation
Arable lands and their farms are lost all over the globe.because of desertification and if the sea levels rise thousands of hectares on coastal lands will b flooded
Northern China is drying up, what once were millions of food producing people, are now hungry refugees ,running for their lives from the all consuming dust storms.
This will have a great effect on world food prices when they start buying at what ever cost, to feed their people.
The farmers have to feed some 70 million more people than the year before but with less topsoil.
Over the last half century,
Population growth & rising incomes have tripled world grain demand from 640 million tons to 1,855 million
In the near future the global farming community will not be able to feed every body ,food prices will continue to rise. .
potable water is getting at critical levels and people are already fighting over water this will only get worse
