You don’t. Why? The Earth isn’t warming right now, is why. It may even be cooling down somewhat.
Five major climate centers around the world agree that average global temperatures have not risen in the past 11 years, according to the BBC. In fact, in eight of those years, global average temperatures dipped a tad.
Yes, there have been several record heat spikes during that time period. The Southern Hemisphere this summer saw the highest land and water temperatures ever recorded, for instance. But overall? Steady as she goes.
Reasons cited range from a slightly cooling Pacific -- a major global heat trap -- as well as renewed questions about the sun’s role in warming (about which there is much debate). Also, it’s possible, some say, that warming itself causes CO2 levels -- which are associated with warming -- instead of the other way around.
As a result, “The depth of the cold of the coming winters will change the social and political climate in ways that only nature can orchestrate,” predicts meteorologist Art Horn.
