Reaching up High – Aerosol Concentrations at EGU 2013

For those with a keen eye, you may have spotted a red balloon soaring high above the EGU Centre this week. The little white box attached underneath is the Light Optical Aerosol Counter (LOAC), a device that has been measuring the aerosols it the air around the conference. Aerosols are air borne particles that can be liquid or solid, natural or manmade. Salt, fog, sand, plaster and carbon are commo ...[Read More]

Meet Future Earth

This week at the EGU General Assembly, we’ve heard how the global environment is changing before our very eyes. As the Earth warms, sea levels rise, and weather patterns shift, the food security, health, and economic prosperity of societies around the world has come under threat. In the Anthropocene, an era dominated by human impact on the natural world, it seems that environmental and development ...[Read More]

Bioengineering Could be the Answer to Dirt-Free Dams

Scientists are building walls of willow trees in the Southern French Alps gullies to trap dirt that blocks hydroelectric dams downstream. Sediment in rainwater washes off the steep valley slopes in the Francon marly basin into gullies. These smaller waterways then feed larger rivers. When the water reaches the slower-moving reservoirs above dams, the sediment drops out and settles behind the barra ...[Read More]

Bookends on Planetary Atmosphere

New results presented this week at the EGU General Assembly have scientists adjusting the assumptions that have longed acted as bookends on the way we understand the evolution of planetary atmospheres. On one side, researchers have identified a previously unrecognised greenhouse effect that could have warmed the early Earth. On the other, the Curiosity rover has uncovered evidence that Mars has lo ...[Read More]
