Earth TOP STORY
Using a climate model that can tag sources of soot from different global regions and can track where it lands on the Tibetan Plateau, researchers have determined which areas around the plateau contribute the most soot -- and where.

Younger Dryas Boundary locations
At the end of the Pleistocene period, approximately 12,800 years ago -- give or take a few centuries -- a cosmic impact triggered an abrupt cooling episode that earth scientists refer to as the Younger Dryas.
This image from Sentinel-1A's radar captures part of Germany's state of Bavaria, with the city of Munich on the right and Augsburg at the centre.
Tiny particles suspended in the air, known as aerosols, can darken snow and ice causing it to absorb more of the sun's energy. But until recently, scientists rarely considered the effect of all three major types of light-absorbing aerosols together in climate models.
In January 2015, the Shire River in Malawi, and Zambezi River in Mozambique were under tight scrutiny. Weeks of torrential rains led these and other rivers to burst their banks displacing 390,000 people across the region.
A NASA camera on the Deep Space Climate Observatory satellite has returned its first view of the entire sunlit side of Earth from one million miles away.
This satellite image covers part of New York City, including the island of Manhattan at the centre, the Brooklyn and Queens boroughs on the right and the Bronx along the top-right.
After several weeks of tectonic rumblings beneath the surface, one of the most active volcanoes in Indonesia began spewing ash plumes and lava into the skies over tropical Asia.
This composite image from 12:00 (UTC) today shows the string of six tropical cyclones currently affecting the Pacific, an unusually high number on a given day.
The sandy and rocky terrain of the Sahara desert in central Algeria was captured in this image by the Sentinel-2A satellite.
Concordia research station in Antarctica is a place of extremes. In winter no sunlight is seen for four months and the typical crew of twelve live in complete isolation.
A new NASA study of ocean temperature measurements shows in recent years extra heat from greenhouse gases has been trapped in the waters of the Pacific and Indian oceans.
The smoke that is billowing from the wildfires currently plaguing Canada have taken the jet stream express into the United States.
Smoke from Alaska and Canada Fires Dives into the Continental U.S.
The Sahara desert's sandy and rocky terrain in central Algeria, captured by the Sentinel-2A satellite in its first-ever scan of Earth on 27 June 2015.
This image over part of the Italian island of Sardinia comes from the very first acquisition by the Sentinel-2A satellite.
In late May 2015, the highest volcano in the Galapagos Islands erupted for the first time in 33 years. The explosive eruption at Wolf volcano on Isabela Island sent volcanic gases and ash roughly 15 kilometers (50,000 feet) into the sky, while lava flowed through a fissure, down eastern and southeastern slopes, and eventually reached the sea.
This image captured by Sentinel-1A's radar on 1 April 2015 shows a central region of California in the US. The San Andreas Fault - the border between two tectonic plates - is visible as a somewhat straight line running from the upper-left corner of the image to the bottom centre.
The ESA-developed Sentinel satellite Sentinel-2A was launched today, adding a high-resolution optical imaging capability to the European Union Copernicus environmental monitoring system.
