Global Warming’s Comeback

[This article consists of an illustration. Please see hardcopy of magazine or PDF.]

1. A PAUSE IN WARMING

Researchers say a number of factors may have contributed to the hiatus. For one, volcanic eruptions released gases blocking the sun’s rays from heating up the earth’s surface. Shifting climate patterns in the world’s oceans have also strengthened trade winds, leading the earth’s oceans to absorb heat.

2. THE HEAT IS ON AGAIN

The Met Office says El Niño’s climate pattern, which will continue this year and next, will increase Pacific Ocean temperatures, while humans continue to emit greenhouse gases that contribute to global warming.

3. TEPID RESPONSE

Negotiators from 195 countries around the world are meeting in Paris this fall to craft an agreement to prevent a global temperature increase from exceeding 3.6°F by 2100. An agreement is likely, but scientists warn that the goal may already be out of reach.
