Rail Travel Pollutes as Much as Flying: Study

(Newser) - Train riders might not actually have that much to lord over their jet-setting rivals as far as pollution goes, Scientific American reports. A new study shows that although planes emit three times more greenhouse gasses per passenger per mile than trains, the industrial emissions necessary to rail infrastructure makes the...

Dairy Teams Seek Greener Cow Burps

Methane production drops after farms adopt new feed

(Newser) - Cow belches have been called a bigger environmental threat than cars and trucks—and now dairy groups are taking steps to keep dangerous burps to a minimum, the New York Times reports. One Vermont farmer has seen his cows’ methane emissions drop 18% after boosting the alfalfa and flaxseed in...

Experts Get the Poop on Penguins

(Newser) - Emperor penguin droppings are so concentrated that the reddish-brown guano has been spotted from space, reports the Times of London. That's a good thing because it's helping scientists pinpoint colonies of the giant birds in Antarctica and help experts track climate change affects. “The ice gets pretty dirty and...

Climate Change 'Affects 300M': Think Tank

(Newser) - Global warming is affecting 300 million people and taking 300,000 lives per year, according to the first wide-ranging research on the impact of climate change. Released by former UN secretary general Kofi Annan's think tank, the study says floods, fires, storms, and heatwaves are costing the world more than...

Warming Earth Down to Its 'Last Chance': Charles

Prince warns of catastrophe if world continues to balk at taking action

(Newser) - Prince Charles warned yesterday that the world's unwillingness to take action on climate change means disaster is looming, the Daily Telegraph reports. The prince, addressing the Nobel Laureates Symposium, said that although a "mercifully small—if vociferous—number" of people still reject the science of climate change, a far...

Energy Chief: Paint World White to Stop Warming

Chu calls for 'new revolution' to combat climate change

(Newser) - A colossal coat of paint could do as much to slow global warming as removing all cars from the Earth for 11 years, Energy Secretary Steven Chu told a climate change conference yesterday. Chu said painting roofs white and making roads a lighter color—which would reflect heat and reduce...

Belgian City Goes Vegetarian, Weekly

Ghent officials, schoolkids to observe "veggie day"

(Newser) - In good news for Belgian cows, the city of Ghent this week begins a weekly “veggie day,” on which officials will go vegetarian, the BBC reports. The move is an effort to cut greenhouse gases, almost a fifth of which come from livestock, the UN says; the city...

Antarctic Ice Shelf Crumbles

Scientists say global warming has made huge Wilkins Ice Shelf unstable

(Newser) - A huge ice shelf in the western Antarctic has become unstable and is beginning to fracture into icebergs, the Telegraph reports. Images from space show that the Jamaica-sized Wilkins ice shelf has lost 270 square miles of ice in recent weeks. Scientists expect the "fragile and vulnerable" shelf to...

Industry Muffled Own Scientists on Warming

Coal, oil, companies suppressed experts' findings for years

(Newser) - A coalition of industries linked to fossil fuels lobbied for more than a decade to cast doubt on global warming—while the companies' own scientists advised them that climate change was irrefutable, the New York Times reports. The Global Climate Coalition, financed by the oil, coal, and auto industries, conducted...

Fires Fuel Climate Change, More Fires

Scientists warn that fires must be included in climate models

(Newser) - Climate change calculations have missed the blazingly obvious, according to a new report from a global group of scientists. They warn that forest fires—generally considered to be a part of natural cycles—are a key driver of climate change, releasing vast amounts of carbon into the atmosphere and creating...

World's Rivers Running Low: Study

(Newser) - The world’s rivers are drying up as climate change worsens and the demand for water increases, the BBC reports. Researchers studying 925 major waterways—from the Ganges to the Colorado—found significantly less fresh water flowing into oceans in 2004 than 50 years earlier. If the trend continues, the...

Dim Sun Is Cold Comfort to Scientists

(Newser) - The sun may be heading for one of its dimmest periods in history, but that doesn't mean the big star is joining the battle against global warming, according to scientists. The sun hit a 100-year low in sunspot activity last year, reports the Telegraph.

Leaded Gas May Have Slowed Climate Change

(Newser) - The dirty fumes of leaded gas may have curbed global warming for a few decades in the 20th century, the New Scientist reports. Researchers in Washington state have found that lead particles are key to creating ice crystals, which help form clouds—which aid global cooling by reflecting sunlight back...

EPA's CO2 Ruling May Have Huge Impact

(Newser) - The EPA's decision today to declare carbon dioxide and five other greenhouse gases dangerous pollutants could have enormous consequences for US businesses, writes Andy Stone in Forbes. The big winner: green technology. The ruling could eventually give the EPA unprecedented regulatory control over everything from power plants to oil refineries...

Third-World Cookstoves Ignite Carbon Debate

Cutting soot could slow climate change by 18%

(Newser) - A simple $20 stove may be the ticket to slowing global warming by nearly a fifth, the New York Times reports. Soot—otherwise known as black carbon—is the second-biggest contributor to climate change, and it spews from hundreds of millions of simple stoves in developing countries daily. Installing solar-powered...

Battered Australia a Preview of Climate Devastation

Country grapples with drought, wildfires, and heat

(Newser) - Pummeled by drought, wildfires, and heat, Australia may be offering the world a preview of what’s to come as the planet warms, experts say. “Australia is the harbinger of change,” says a paleontologist. Many say climate change has already taken a human toll in the 173 killed...

White House Mulls Drastic Action on Climate Change

Geo-engineering could be last resort, Holdren says

(Newser) - Global warming may get to the point where drastic "geo-engineering" measures to cool the earth will be necessary, President Obama’s top science adviser tells the AP. John Holdren said shooting reflective particles into the upper atmosphere to reflect some sunlight is a last resort, but one he's raised...

Post Story on Arctic Calls Out Post Columnist Will

(Newser) - George Will takes a fair amount of flak for his view that global warming is a bunch of hooey. Now he's taking it from the news pages of his own paper, writes David Roberts in Grist. A story today in the Washington Post cites evidence showing a decline in Arctic...

Snapped Antarctica Ice Bridge Stokes Warming Alarm

First break for massive, retreating shelf

(Newser) - A massive 25-mile-long Antarctic ice bridge between a Jamaica-sized ice shelf and an island has broken in what scientists are calling an alarming sign of runaway global warming, the BBC reports. It was the first time the shelf, which has been retreating for years, has lost a link holding it...

Scientists Solve Riddle of 'Medieval Warm' Era

Finding debunks climate-change deniers

(Newser) - Atlantic ocean winds warmed Europe 1000 years ago, scientists say, scuttling a key argument used by those who deny current pollution is causing climate change. The natural regional phenomenon pinpointed as the cause of the Medieval Warm Period no longer exists and cannot be responsible for current global warming, reports...
