A model showing the impact of coastal erosion on eastern communities in Grenada is on display at a  community center in Grenville, Grenada. The people along this vulnerable stretch of eastern Grenada have been watching the sea eat away at their shoreline in recent decades, a result of destructive practices such as sand mining and a ferocious storm surge made worse by climate change, according to researchers with the U.S.-based Nature Conservancy, who have helped locals map the extent of coastal erosion.

Amid the blooming of Washington scandals, this bit of news may have been missed.

National Geographic reports:

"An instrument near the summit of Mauna Loa in Hawaii has recorded a long-awaited climate milestone: the amount of carbon dioxide in the atmosphere there has exceeded 400 parts per million (ppm) for the first time in 55 years of measurement—and probably more than 3 million years of Earth history.

"The last time the concentration of Earth's main greenhouse gas reached this mark, horses and camels lived in the high Arctic. Seas were at least 30 feet higher—at a level that today would inundate major cities around the world. The planet was about 2 to 3 degrees Celsius (3.6 to 5.4 degrees Fahrenheit) warmer. But the Earth then was in the final stage of a prolonged greenhouse epoch, and CO2 concentrations were on their way down. This time, 400 ppm is a milepost on a far more rapid uphill climb toward an uncertain climate future."
