"What a difference a year makes. In late 2010, solar panel makers were sold out, Germany was gobbling up record numbers of the clean energy systems, and new markets were steadily growing."
"Climate change's laundry list of impacts — melting glaciers and rising sea levels, shifts in timing for bird migration and flower budding, a poleward shift of species — just got a new addition: shrinking species."

"Scientists have mapped out the entire genetic map of the Black Death, a 14th century bubonic plague that killed 50 million Europeans in one of the most devastating epidemics in history.
The work, which involved extracting and purifying DNA from the remains of Black death victims buried in London's "plague pits," is the first time scientists have been able to draft a reconstructed genome of any ancient pathogen.
"UNITED NATIONS -- Conservationists and the international fishing industry are gearing up for another showdown over the fishing method known as bottom trawling next month, when U.N. officials return to what has probably been the most intensely debated fisheries issue to feature here over the last decade."
"America must stop promoting the production of biofuels if there is to be any real progress in addressing spiking global food prices and famine, such as seen in the Horn of Africa, an authoritative thinktank has warned."
"TOKYO — Even as Japan plans to phase out nuclear power as too risky for domestic use, the government is supporting a new push by Japanese industry to sell nuclear power technology to other countries."
Forests moderate global warming by pulling carbon dioxide out of the atmosphere. But scientists can't predict whether warming will cause major forests to die back, causing a vicious cycle that will make global warming worse.
"BRUSSELS -- Opportunities in oil and natural gas have rarely been so bountiful. New finds and technological advances and fresh access to some countries are pushing exploration and production into areas once considered peripheral.
Some of the most promising new fields are in deep water off the coast of Brazil. Experts say they could yield as much oil as the North Sea. There have been significant strikes off the coast of French Guiana, north of Brazil, and off Ghana in West Africa.
"Consider this: The average person’s body contains about 100 trillion cells, but only maybe one in 10 is human. ... The human cells that form our skin, eyes, ears, brain and every other part of our bodies are far outnumbered by those from microbes, primarily bacteria but also viruses, fungi and a panoply of other microorganisms. ... A growing body of evidence indicates that the microbial ecosystems that have long populated our guts, mouths, noses and every other nook and cranny play crucial roles in keeping us healthy."
"PANAMA CITY — With just weeks to go before UN talks on climate change open in South Africa, negotiators have shifted their goal from striking a historic deal to ensuring that the global system survives."
