an increase in the earth's average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect.
This graph shows how much the global temperatures have gone up since 1860. The blue dots and lines indicate what the global temperature was each year. The red line indicates what the global temperature was over five years. Both lines are averages, but notably increase up into the 2000's.

Our future on earth isn't looking too good with the amount of greenhouse gasses we are emitting onto the planet. Over time greenhouse gases will cause problems such as an increase in the Earth's average temperature, influence on precipitation, reduce ice and snow cover, a raise in sea levels, and more acidic oceans.

Global Warming Cartoons
This cartoon is trying to say ocean levels are rising drastically. The artist shows this through animation using sharks. Within five years, that island in the background will be gone due to global warming, submerged far enough into the water that the sharks can swim over and eat the man sitting there.
This cartoon is telling us about what the temperature change will be like at some point from now because of global warming. It is a powerful cartoon because it looks like the two people are at a lake or the beach, but in fact, they are in a place where it should be cold enough for an igloo.
This cartoon shows us what it will be like for the polar bears way up north. There is no ice for them because it all melted, and they are trying to stay cool by using a fan. The fan wouldn't really happen in real life, but it shows that polar bears will struggle to meet their living conditions. Global warming could potentially make animals such as the polar bear go extinct.
