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.

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.

Agouron Geobiology Field School!

Greetings from scenic Timmins Ontario! I will be spending the next 9 days with a bunch of geologists, biologists, chemists, planetary scientists, and all around smart people, learning about the geology of the Abitibi Greenstone Belt near Timmins. In particular, we will be talking a lot about the origin of life, and how this chunk of ancient crust on Earth can (or cannot) be used as an analog for Mars …
