The Fate of Trees: How Climate Change May Alter Forests Worldwide. In May 2011, a postdoctoral student at Los Alamos National Laboratory named Park Williams set out to predict the future of the dominant iconic conifers of the American Southwest — the Douglas fir, the piñon pine and the ponderosa pine.
As the planet warms, the Southwest is projected to dry out and heat up unusually fast — few places will be more punishing to trees. Williams couldn't rely on climate models, whose representations of terrestrial vegetation remain crudely unspecific. How air conditioning is actually making us hotter.

Acquired 1985 - 2012download large image (7 MB, JPEG, 5101x3188) acquired 1985 - 2012download large Eastern Europe image (21 MB, JPEG, 11802x11401) When the Soviet Union collapsed in 1991, the political and economic effects were profound for the 290 million people under its rule.
But the effects were not limited to the people. Changing political times also led to rapid changes for forests in Russia and the Eastern Bloc countries. After compiling a new satellite-based data set, a team of scientists has published maps showing how Eastern Europe’s forests have changed over 27 years. “Forests generally recovered quickly,” noted Potapov. Across the study area, forest cover grew by 4.7 percent, increasing from 216 million hectares (533 million acres) in 1985 to 226 million hectares (558 million acres) in 2012.
Acquired 1985 - 2012 Timber harvesting was the primary cause of forest change, accounting for more than 90 percent. Globaïa. Welcome to IRENA-Global-Atlas. The nine planetary boundaries. Everything I thought I knew about water in California is wrong. This piece started out as a confident prescription for California’s drought ills.
But when I began writing, I kept coming across things that seemed confusing or contradictory. And each time I went to the experts to clarify, they’d explode all my basic assumptions. So instead of writing that piece, here’s a list of all the (misguided) conventional wisdom I had absorbed set right — or, at least, clarified. California hasn’t forced agriculture to cut water use: A myth. This Is How Much Water It Takes To Make Your Favorite Foods. Extensive drought has Californians thinking twice about running the tap while brushing their teeth or taking that 20-minute shower.
But what some people don't realize is that a huge portion of our water footprint is "hidden," meaning it's used for the things we eat or wear, and for the energy we use. Globally, agricultural production accounts for 92 percent of our water footprint. In the United States, meat consumption alone accounts for a whopping 30 percent of our water footprint. So exactly how much water do the foods you eat require? Report-48-WaterFootprint-AnimalProducts-Vol1.pdf. Thanks to These Dutch Engineers, We May Soon Be Getting Our Food From Skyscrapers. By 2050, the world might find itself in a critical food shortage.
It's a scary thought, but one group is developing a clever way to combat that with a plan they claim can grow enough fresh produce to feed the world in a space one-third the size of Hawaii. To make this happen, PlantLab, a Dutch agriculture firm, wants to construct "plant production units," spaces made for growing plants and vegetables. So this climate walks into a bar … It’s going to be a big year for the climate, with a major global summit in Paris this fall and the U.S. presidential campaign heating up.
Stakes are high, expectations are middling, and anyone who works in this field is walking around with a mixture of Dread, Fatigue, Commitment, and Curiosity (look for that telltale DFCC expression on our faces). Avidly / The Inhuman Anthropocene. Browse Princeton Catalog in Princeton-Primers-in-Climate. Published Books | Forthcoming Books | Reviews Princeton Primers in Climate is a new series of short, authoritative books that explain the state of the art in climate-science research.
Written specifically for students, researchers, and scientifically minded general readers looking for succinct and readable books on this frequently misunderstood subject, these primers reveal the physical workings of the global climate system with unmatched accessibility and detail. Get the science right to value nature.
An international group of scientists, industry representatives and policymakers wants to set guidelines for the science behind valuing nature.
The group has published new guidelines in the latest edition of Science on how to value the benefits and services that nature provides, known as ecosystem services. The guidelines will help governments, policy-makers and business leaders make more informed decisions about major projects that impact ecosystems. The Wreck of the Kulluk. Photo In 2005, Royal Dutch Shell, then the fourth-largest company on Earth, bought a drill rig that was both tall, rising almost 250 feet above the waterline, and unusually round.
The hull of the Kulluk, as the rig was called, was made of 1.5-inch-thick steel and rounded to better prevent its being crushed. A 12-point anchor system could keep it locked in place above an oil well for a full day in 18-foot seas or in moving sea ice that was four feet thick. The Real Reason U.S. Gas Is So Cheap Is Americans Don't Pay the True Cost of Driving. Amid all the celebration over America's plunging gas prices—down some 40 percent since June—it's easy to forget a very basic fact: in a global sense, U.S. fuel has been cheap for years.
In late 2012, for instance, the United States ranked toward the bottom of a world list of gas prices, wedged between the likes of Tunisia and Chad on one side and Russia and Kazakhstan on the other. Most first-world countries paid at least double what America did then, just as they do today. The situation is hardly a happy coincidence for U.S. motorists.
On the contrary, American fuel prices are kept down artificially by low gas taxes that fail to address the true social cost of driving. Ocean Acidification, The Other Carbon Dioxide Problem. Over the past decade, ocean acidification has started to receive recognition outside science, though primarily as another weapon in the 'carbon dioxide' culture war on the modern world, similar to methane being discussed this year. Politics aside, it is a vital area for study and a new article outlines three major challenges to understanding the real issues and effects: It needs to expand from single to multiple drivers, from single species to communities and ecosystems, and from evaluating acclimation to understanding adaptation. For the scientific community, it is obvious that ocean acidification does not occur in isolation.
Rising temperatures, loss of oxygen, eutrophication, pollution and other drivers happen simultaneously and interact to influence the development of marine organisms and communities. A Strange New Gene Pool of Animals Is Brewing in the Arctic - Issue 101: In Our Nature. The journey began in spring 2010, just as the sea ice surrounding the North Pole began its annual melt.
Two bowhead whales, 50-foot-long behemoths that scour the Arctic seas for plankton, each started from their homes on opposite sides of North America—one in the Beaufort Sea north of Alaska, the other in Baffin Bay on the west side of Greenland. As the summer progressed, sea ice shrank (to its third-lowest cover in the last 30 years), and the whales swam toward each other through the now ice-free passage above the continent. Two independent teams of scientists from Canada and the United States watched the whales closely via satellite. The Freedom Tower Was Supposed to Be the Greenest Building in America. So What Went Wrong? Under pressure to get a publishing giant into the iconic tower, the site's developers may have sacrificed a core part of its green plans. —James West on Mon. December 8, 2014 6:00 AM PDT. 8599.pdf. Design Science Primer. Comprehensive, anticipatory design science is “the effective application of the principles of science to the conscious design of our total environment in order to help make the Earth’s finite resources meet the needs of all of humanity without disrupting the ecological processes of the planet.”
The term “design science” was coined by Buckminster Fuller to characterize his unique approach to solving complex problems. Starting With the Universe: Design Science Now. Data-driven Insights on the California Drought (12/8/2014 8:33:13 AM) Environmental news. New global maps detail human-caused ocean acidification. A team of scientists has published the most comprehensive picture yet of how acidity levels vary across the world's oceans, providing a benchmark for years to come as enormous amounts of human-caused carbon emissions continue to wind up at sea. "We have established a global standard for future changes to be measured," said Taro Takahashi, a geochemist at Columbia's Lamont-Doherty Earth Observatory who published the maps with his colleagues in the August issue of the journal Marine Chemistry.
