A revolutionary new approach to measuring changes in forest carbon density has helped WHRC scientists determine that the tropics now emit more carbon than they capture, countering their role as a net carbon “sink.”

Hurricane Lee continues to strengthen in the Central Atlantic Ocean, and the tiny hurricane appeared well-organized with a clear eye in satellite imagery.

India has launched a new $2.5 billion initiative to provide power to the 40 million households in the country that still don’t have electricity. The project aims to electrify the homes — which represent about a quarter of India’s households — by the end of 2018, Reuters reported.

NASA’s Aqua satellite and Global Precipitation Measurement mission, or GPM, satellites have been peering into what appears to be a somewhat lop-sided Hurricane Maria. The storm appears asymmetric because vertical wind shear is pushing clouds and showers to the eastern side of the storm.

On Sept. 27, NHC forecaster Daniel Brown noted, “Deep convection and banding has increased over the eastern and northeastern portion of the large circulation of Maria since yesterday.”

One June day in the year 793, men in ships landed on Lindisfarne, an island off eastern England occupied by a monastery. The men, apparently from the north, plundered treasures, overthrew altars and set fire to buildings. They killed some monks and carried others off in chains; others, they stripped naked and left behind to the mercies of the weather. The attack shocked European Christian society. They came to mark it as the official start of the Viking Age, when Norse raiders ranged as far as the southern Mediterranean and northern Asia, before seemingly fading out some 250 years later.

Latest satellite images reveal a new 100-square-mile iceberg emerging from Antarctica’s Pine Island Glacier. The calving event did not come as a complete surprise, but is a troubling sign with regards to future sea level rise.

Famous for its weather forecasts, the Old Farmer’s Almanac has published its predictions for the coming year—but don’t believe everything you read.

The folksy pocket-sized magazine has been a regular go-to for farmers and other fans during fall harvest season since it first began publishing in 1792. As cosy and comforting as pumpkin pie, it offers everything from home remedies to food recipes—but the long-range weather predictions that fill many of its pages are nothing but pure guesswork, said a University of Alberta weather modelling expert.

Arctic sea ice extent has likely reached its minimum extent for the year, at 4.64 million square kilometers (1.79 million square miles) on September 13, 2017, according to a team of international scientists. The 2017 minimum is the eighth lowest in the 38-year satellite record. The Arctic sea ice minimum marks the day – typically in mid-September – when sea ice reaches its smallest extent at the end of the summer melt season.

Since Captain James Cook’s discovery in the 1770s that water encompassed the Earth’s southern latitudes, oceanographers have been studying the Southern Ocean, its physics, and how it interacts with global water circulation and the climate.

Tropical Depression Pilar weakened to a remnant low pressure area as it continued to crawl north along the west coast of Mexico. Satellite data revealed no circulation center.
