New Paper: Global Kelp Forest Change

Posted by on Nov 16, 2016 in publications | No Comments

Four years ago, I was fortunately enough to lead a working group on the global impact of climate change on kelp forests. Our first research product has just come out in PNAS, and I am incredibly proud of it. In it, we analyze hundreds of data sets of kelp forest change spanning nearly a half century of investigations. We find that 38% of the world’s forests are indeed in decline. Hopefully, the rest are either staying the same or even increasing in some places. There’s a lot to chew on here, with plenty of followup analyses (some focusing on climate change) in the works.

For now, enjoy!
