So, what's all this "Global Warming" talk about, anyway?

*The Merriam-Webster dictionary (1969) defined global warming as a noun meaning "an increase in the earth's atmospheric and oceanic temperatures widely predicted to occur due to an increase in the greenhouse effect resulting especially from pollution."

*The Time for Change website (n.d.) defined global warming as: "the observed and projected increases in the average temperature of Earth's atmosphere and oceans."

Check out these graphs from the Time for Change (n.d.) website. They are great visuals of just how much the earth has warmed up in recent years!

Recently, there has been a switch from referring to this phenomena as "global warming" to referring to it as "global climate change."
