If green house gas emissions do not decrease the globe will increasingly get warmer. The sun's heat enters the atmosphere, some heat will escape, some will be trapped. Carbon dioxide causes the heat to remain in the atmosphere. Without carbon dioxide Earth would very cold, but with the use of fossil fuels and other unsustainable resources we are releasing too much carbon dioxide in the atmosphere. This is causes way too much heat to remain trap. And this is what is causing global warming
