<span>It is important to study healthy individuals and individuals who have had injury to the cerebral cortex. You can compare healthy individuals (control group) to the people who have had damage to the brain. Studying people with damage to the brain can help us draw conclusions if there are any negative effects on mood or personality.</span>

Here are few of the things that scientists think may happen as the temperature rises. Some of them are already happening:
Glaciers melting - Many glaciers are already melting and shrinking throughout the world. If the temperature increases they will continue to melt. This will cause animals that rely on glaciers such as polar bears and other species to become extinct.
Ocean levels will rise - As the glaciers melt, the ocean levels will rise. This could cause flooding in cities located near the coast.
Migration of animals - Animals will migrate to cooler spots as their old habitats get too warm. This could upset the food chain and put some species in danger of extinction.
Extreme weather - Some scientists think that warming will fuel more powerful hurricanes as well as more droughts and flooding in different areas of the world.
Change in ecosystems - cold weather biomes such as the tundra will shrink, while desserts will continue to expand.
Hope this helped :)
