Cleo and Bryce were hard at work for the month of September out in the North Atlantic. Cleo continues collecting data on volatile organic compounds that are cycled among members of the marine microbial community. If cycling becomes uncoupled, these VOCs can be released into the atmosphere with wide ranging climate effects. Bryce was responsible for measuring net primary production, so he spent a lot of time in the rad van (where he can use radiolabeled isotopes). Once in awhile he was free to enjoy the vast sea. The last of the four cruises is coming up quickly in March, 2018…

Scheffers et al. 2016 The footprint of climate change

New review in Science today highlighting the environmental impacts of climate change. Is everyone listening?

From the abstract:

“Understanding shifts in ecological processes can guide human adaptation strategies. In addition to reducing greenhouse gases, climate action and policy must therefore focus equally on strategies that safeguard biodiversity and ecosystems.”

Climate change impacts on ecological processes in marine, freshwater, and terrestrial ecosystems

f1-large

Impacts can be measured on multiple processes at different levels of biological organization within ecosystems. In total, 82% of 94 ecological processes show evidence of being affected by climate change. Within levels of organization, the percentage of processes impacted varies from 60% for genetics to 100% for species distribution.
