Earth Just Had Its Warmest Spring on Record


This year is shaping up to be a hot one—literally.

This past May was officially the warmest on record, the National Oceanic and Atmospheric Administration said in a new report. What’s more, researchers say Earth experienced the warmed spring and first five months of the year on record, too. Land and sea temperatures across the globe were higher than the agency has ever recorded in more than 130 years.

Last month was 1.57 degrees Fahrenheit above the average worldwide of 58.6 degrees, the agency said. And the spring averaged 1.53 degrees above the the typical temperature. In the U.S., May turned out to be the country’s wettest month on record.

How DNA Could Help Catch Elephant Poachers


Every year criminals around the world trade billions of dollars in products derived from wildlife. The elephant trade in particular has rankled government officials around the world with tens of thousands of the large mammals killed in Africa every year—a conservation threat, given the dwindling numbers of elephants in the wild.

Now, scientists say that they may be able to use DNA from government seizes of illegal ivory tusks to trace elephants’ origins, a potentially groundbreaking method for law enforcement. Large-scale poaching, which accounts for more than 70% of the ivory trade, may be confined to just two areas, according to an analysis of the DNA tests published in the journal Science.

“By being able to say that these came from just a couple of areas means that we can target those areas much more efficiently with law enforcement,” said study author Sam Wasser, on a conference call for journalists.
