Collapse of New England’s iconic cod tied to climate change.

For Investigation:   10.3 Excerpt: The Atlantic cod, a fish that came to symbolize bounty to America’s colonial settlers, is on the brink of disappearing, despite years of fishing limits aimed at rebuilding stocks. A new study reveals why: Cod spawning and survival has been hampered by rapid, extraordinary ocean warming in the Gulf of Maine, where sea surface temperatures rose faster than anywhere else on the planet between 2003 and 2014. ...The scientists used satellite data to track the daily sea surface temperature trend in the Gulf of Maine. From 1982 until 2004, they found, temperatures rose by 0.03°C per year, or three times the global mean rate. That warming accelerated sevenfold beginning in 2004, peaking in 2012 with a large “ocean heat wave” that persisted for 18 months, according to the study. ...Using recent Gulf of Maine cod stock as

Greenland Is Melting Away

Brandon Overstreet, a doctoral candidate in hydrology at the University of Wyoming, picked his way across the frozen landscape, clipped his climbing harness to an anchor in the ice and crept toward the edge of a river that rushed downstream toward an enormous sinkhole. If he fell in, “the death rate is 100 percent,” said Mr. Overstreet’s friend and fellow researcher, Lincoln Pitcher. But Mr. Overstreet’s task, to collect critical data from the river, is essential to understanding one of the most consequential impacts of global warming. The scientific data he and a team of six other researchers collect here could yield groundbreaking inf

A bright future

Lovins about Philip Warburg's book "Harness the Sun -- America's Quest for a Solar-Powered Future For Investigation:   10.3 The review is inspiring and restorative of optimism that we can emerge from the dark age of fossil fuel energy systems. Excerpts: "...And while solar power added 32% of new U.S. generating capacity in 2014, in 2013 alone, China added more photovoltaic (PV) capacity than the United States has added since Bell Laboratories unveiled the first modern solar cell in 1954." "...The solar industry’s pace drives and is driven by steeply falling prices (low prices make us buy more PVs, so they get cheaper, so we buy more, and so on). Spurred by German success, which inspired massive Chinese production, solar modules went on a price path akin to sneakers, falling more than 100-fold since 1975 and by 80% just in the past 5 yea
