For Investigation:   10.3 Excerpt: For the solar and wind industries in the United States, it has been a long-held dream: to produce energy at a cost equal to conventional sources like coal and natural gas. That day appears to be dawning. The cost of providing electricity from wind and solar power plants has plummeted over the last five years, so much so that in some markets renewable generation is now cheaper than coal or natural gas. ...In Texas, Austin Energy signed a deal this spring for 20 years of output from a solar farm at less than 5 cents a kilowatt-hour.  ...According to a study by the investment banking firm Lazard, the cost of utility-scale solar energy is as low as 5.6 cents a kilowatt-hour, and wind is as low as 1.4 cents. In comparison, natural gas comes at 6.1 cents a kilow

Record Drought Reveals Stunning Changes Along Colorado River

At "full pool," Lake Powell spans 254 square miles (660 square kilometers)—a quarter the size of Rhode Island. The lightning bolt-shaped canyon shore stretches 1,960 miles (3,150 kilometers), 667 miles (1,073 kilometers) longer than the West Coast of the continental United States. The reservoir serves multiple purposes. It stores water from the Upper Basin states of Wyoming, Utah, New Mexico, and Colorado so that the Lower Basin states of California, Nevada, and Arizona can receive their allotted half of the Colorado River; i

Climate Change Threatens to Strip the Identity of Glacier National Park

A century ago, this sweep of mountains on the Canadian border boasted some 150 ice sheets, many of them scores of feet thick, plastered across summits and tucked into rocky fissures high above parabolic valleys. Today, perhaps 25 survive. In 30 years, there may be none. A warming climate is melting Glacier’s glaciers, an icy retreat that promises to change not just tourists’ vistas, but also the mountains and everything around them. Streams fed by snowmelt are reaching peak spring flows weeks earlier than in the past, and low summer flows weeks before they used to. ...Many of the mom-and-pop ski areas that once peppered these mountains have closed.  ...For wildlife, Dr. Fagre said, the imp

A Year In The Life Of Earth's CO2

Plumes of carbon dioxide in the simulation swirl and shift as winds disperse the greenhouse gas away from its sources. The simulation also illustrates differences in carbon dioxide levels in the northern and southern hemispheres and distinct swings in global carbon dioxide concentrations as the growth cycle of plants and trees changes with the seasons....

U.S. and China Reach Climate Accord After Months of Talks

http://www.nytimes.com/2014/11/12/world/asia/china-us-xi-obama-apec.html Source:   Mark Landler, The New York Times For Investigation:   10.3 Excerpt: BEIJING — China and the United States made common cause on Wednesday against the threat of climate change, staking out an ambitious joint plan to curb carbon emissions as a way to spur nations around the world to make their own cuts in greenhouse gases. The landmark agreement, jointly announced here by President Obama and President Xi Jinping, includes new targets for carbon emissions reductions by the United States and a first-ever commitment by China to stop its emissions from growing by 2030. Administration officials said the agreement, which was worked out quietly between the United States and China over nine months and included a letter from Mr. Obama to Mr. Xi proposing a joint approach, could galvanize efforts to negotiate a new global climate agreement by 2015. It was the signature achievement of an unexpectedly

U.N. Panel Issues Its Starkest Warning Yet on Global Warming

The gathering risks of climate change are so profound that they could stall or even reverse generations of progress against poverty and hunger if greenhouse emissions continue at a runaway pace, according to a major new United Nations report. Despite growing efforts in many countries to tackle the problem, the global situation is becoming more acute as developing countries join the West in burning huge amounts of fossil fuels, the Intergovernmental Panel on Climate Change said here on Sunday. Failure to reduce emissions, the group of scientists and other experts found, could threaten society with food shortages, refugee crises, the flooding of major cities and entire island nations, mass extinction of plants and animals, and a climate so drastically altered it might become
