Permafrost loss dramatically changes Yukon River chemistry
Permafrost loss due to a warming Alaska is leading to changes in the chemistry of the Yukon River Basin with potential global climate implications. This is the first time a Yukon River study has been able to use long-term continuous water chemistry data to document hydrological changes over such an enormous geographic area and long time span.

Rare molecule on Venus could shed light on planet’s weather
Scientists’ keen detective work may have solved one of Venus’s oldest secrets: why the planet’s atmosphere absorbs ultraviolet light of a specific frequency. The new findings could help scientists better understand Venus’s thick atmosphere and its heat-trapping clouds, according to the study’s authors.

Chemicals unleashed: Air quality during the Deepwater Horizon oil spill
For me, the term volatile organic compounds sounds like a group of renegade chemicals on a bender. Sadly, there were no pictures of “chemicals gone wild” in this morning’s poster session A31B Gulf of Mexico Air Quality and Climate Impacts: Urban and Regional Pollution Including the 2010 Oil Spill I Posters. Bottom line? The oil released when the rig exploded and sank not only pumped pollution into the ocean. It affected the air too.
How do you catch a cloud and pin it down?
At first glance, fluffy clouds seem innocuous. On lazy summer days, they take on whatever form our imaginations can conjure–morphing from fat little bunnies to fire-breathing dragons as the afternoon fades into evening. But if you’re a climate scientist, that mutability is not so fun. Ever changing, their dynamic nature is the bane of many a modeler’s existence.
