If global warming were to raise temperatures 1.5°c to 4.5°c, what would most-likely happen? we'd get a better tan. polar ice caps would melt, increasing sea levels. wildlife would have to migrate or die. the ozone layer would be depleted. hurricanes and typhoons could increase in intensity. glaciation would occur.

The correct answers are:

- Polar ice caps would melt, increasing sea levels;

Because of the rise of the temperatures, the permafrost, glaciers, and polar ice caps would mostly melt. As they melt, they will increase the sea levels significantly because they will introduce much more water into the the seas and oceans.

- Wildlife would have to migrate or die;

With increasing sea levels, as well as change of habitats, lot of animals would find themselves in situation where they will have to migrate, because if they don't, they will find themselves in water and drown, or starve to death.

- Hurricanes and typhoons could increase in intensity;

Because the water in the sea levels will increase, and the water bodies will become even bigger, the hurricanes and typhoons will be able to become stronger and more intense, thus be more destructive as well.
