CryoSat conquers ice on Arctic lakes

The rapidly changing climate in the Arctic is not only linked to melting glaciers and declining sea ice, but also to thinning ice on lakes. The presence of lake ice can be easily monitored by imaging sensors and standard ...

Ice volume calculated anew

Researchers have provided a new estimate for the glacier ice volume all around the world, excluding the Greenland and Antarctic ice sheets. Their conclusion: previous calculations overestimated the volume of the glaciers ...

Sierra snowpack could drop significantly by end of century

A future warmer world will almost certainly feature a decline in fresh water from the Sierra Nevada mountain snowpack. Now a new study by the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) that ...

NASA data find some hope for water in Aral Sea basin

(Phys.org) —A new study using data from NASA satellite missions finds that, although the long-term water picture for the Aral Sea watershed in Central Asia remains bleak, short-term prospects are better than previously ...

Steroids control gas exchange in plants

Plants leaves are sealed with a gas-tight wax layer to prevent water loss. Plants breathe through microscopic pores called stomata (Greek for mouths) on the surfaces of leaves. Over 40% of the carbon dioxide, CO2, in the ...
