The what ifs The what ifs
Scientist believe that if we continue on the Scientist believe that if we continue on the path we have been following we are in for a path we have been following we are in for a total global climate change. Possible affects total global climate change. Possible affects includeinclude Upper hemisphere tempter severely affectedUpper hemisphere tempter severely affected Oceanic flow disturbed or non existent Oceanic flow disturbed or non existent
This will cause the flow of warm water to the upper This will cause the flow of warm water to the upper hemisphere to be halted possibly causing a Mini ice age hemisphere to be halted possibly causing a Mini ice age
Weather will become more violent and more frequent Weather will become more violent and more frequent in the lower hemisphere in the lower hemisphere

Affects of melting iceAffects of melting ice
Ice reflects sunlight Ice reflects sunlight Because of shrinking arctic ice there is less reflected Because of shrinking arctic ice there is less reflected
sunlight and more water to absorb heat from the sun.sunlight and more water to absorb heat from the sun. Therefore the less ice there is the faster it will melt.Therefore the less ice there is the faster it will melt.
With less ice there is less habitat for arctic With less ice there is less habitat for arctic animals such as polar bears for example.animals such as polar bears for example.
When the arctic ices melt it releases green house When the arctic ices melt it releases green house gases from the soil underneath ice and in the ice gases from the soil underneath ice and in the ice its self that have been trapped for millions of its self that have been trapped for millions of years. years.

The government and other companies have been finding The government and other companies have been finding knew alternative sources of power that do not emit CO2 or knew alternative sources of power that do not emit CO2 or other green house gas. Which fit into the same category as other green house gas. Which fit into the same category as global warming issues and true solutions remain unclear global warming issues and true solutions remain unclear
