“Biogeochemistry: Long-term effects of permafrost thaw” by Donatella Zona

http://www.nature.com/nature/journal/v537/n7622/full/537625a.html

Carbon emissions from the Arctic tundra could increase drastically as global warming thaws permafrost. Clues now obtained about the long-term effects of such thawing on carbon dioxide emissions highlight the need for more data.

“If San Diego lost its forest” by Walter Oechel

http://inewsource.org/2016/09/28/san-diego-forest-loss/

The forests of San Diego County that have shaded 500 generations of local people and provided pine needle bedding, oak woodland and spiritual renewal could disappear. Overly intense fires in quick succession, along with drought, borer insects and climate extremes is laying waste to trees and creating a hostile environment for regrowth.

Bad news: Scientists say we could be underestimating Arctic methane emissions

Arctic permafrost has become a recent star in the climate change conversation, capturing the attention of scientists, activists and policymakers alike because of its ability to emit large quantities of carbon dioxide as well as methane — a particularly potent though relatively short-lived . . . → Read More: The Washington Post interview with Dr. Zona and Dr. Oechel about cold-season methane emissions in the Arctic

GCRG on LI-COR NewsLine: Measure Methane Where it Matters: Part II, Barrow, Alaska

“Although many scientists agree that the current warming trend is likely to continue, it is unknown whether a warmer climate will turn the Arctic Coastal Plain from a sink to a source of greenhouse gases…. Cove Sturtevant and Dr. Walt Oechel from San Diego State University in California are addressing some of these questions . . . → Read More: GCRG on LI-COR NewsLine: Measure Methane Where it Matters: Part II, Barrow, Alaska

What is a “Feedback Loop?”: Dr. Oechel on ABC News

Recently, it was another beautiful, sunny day out on the Arctic tundra. Scientists say the Arctic is melting — and fear it could help send Earth into a global warming tailspin. It may sound nicer that way — but it’s a big problem for the Earth. Scientists say the warm weather adds to global . . . → Read More: What is a “Feedback Loop?”: Dr. Oechel on ABC News

Dr. Oechel on KPBS Radio: Realities of Global Warming

Tidal waves, tornadoes, and the big freeze. The Day After Tomorrow is the latest disaster movie to hit the big screen. But how much of it is based on fact? We’ll talk about the realities of global warming.
