(updated with a video: 4/27/2014) Bioenergy and biofuels have an important role to play in lowering the use of carbon-intensive fossil fuels – a point underscored by the IPCC report which confirmed the need for further research to improve such technology.
Sometimes there are BIG lessons to be learned from little things. Such is the case with this little movie offered by George Monbiot. It teaches the connectivity of the universe while tugging at your heart strings. No small feat.
by Tim Radford, Climate News Network. Global warming will be bad. Geoengineering could make it worse. Once again, a research team has considered all the benefits of climate technofix – that is, deliberate steps to neutralize the consequences of unrestrained greenhouse gas emissions – and come to a grim conclusion.
It’s being billed as “the biggest story of our time.” This weekend viewers of Showtime, the US cable channel, will be watching the first of an nine-part documentary series on climate change: some of the biggest names in Hollywood are involved.
Can the U.N. Intergovernmental Panel on Climate Change most recent report or a star-studded Showtime mini-series change the way people talk and think about climate change? Katharine Hayhoe urges her fellow climate scientists to ramp up their messaging game.
Forget the cost of mitigating climate change, say two researchers. It’s impossible to work out how much it will be – and whatever it is, we should do it anyway. Two researchers who tried to work out the economics of reducing global climate change to a tolerable level have come up with a perhaps surprising answer...
GMOs seem to polarize people more than almost any other topic, including evolution or climate change. And the debates around GMOs — especially whether they are safe to eat or safe to grow — can get very fierce.
What happens when demand outstrips supply for natural resources needed to make everything from mobile phones and microwaves to toasters and tankers? Enter the circular economy.
Warming in the Arctic has now reached the northernmost sections of the Greenland ice sheet. After a long period of stability (more than 25 years), we have found in a new study of the region that the northeast section of the ice sheet is no longer stable. This means global sea levels may rise even faster than was previously anticipated.
The potential of consumers to go off-grid in a major way in the US depends on a number of factors. The falling cost of solar we know about, and the rising cost of poles and wires is also well understood. The new element is the falling cost of battery storage. This has been debated for some years...
Ice in the Arctic continues to retreat. It’s long been established that Arctic ice is on the retreat but it’s the pace of change that’s surprising scientists: latest studies show the region is at its warmest since 40,000 years.
by Paul Farrell, The Guardian. The 2014 State of the Climate report. a joint undertaking by the CSIRO and Bureau of Meteorology, found that Australia’s temperature is predicted to rise by 1°F to 2.7°F by 2030; in comparison, between 1910 and 1990 the temperature rose by 1°F.
by Paul Brown. It is not just the extreme cold that birds have had to cope with in recent British winters, scientists have found, but the unpredictability with which the weather often now changes.
Increasingly common false spring events are leaving crops and wild plants vulnerable to subsequent freezes, creating a cascade of consequences for ecosystems. The spring of 2012 was the earliest recorded across the United States since 1900.
The world faces a serious water crisis, warned former heads of government and experts recently in a book that identifies a multitude of associated security, development and social risks, including food, health, energy and equity issues.
Plastic microbeads from cosmetic products have been filling up our lakes and rivers. New York State is the first seeking to ban them, and others aren't far behind. Last year scientists reported finding tens of millions of microbeads bobbing to the surface in Lake Erie.
In the wake of West Virginia's chemical spill, residents turned to bottled water. But that's even less regulated than what comes out of our tap. The real solution: let information flow.
Bill McKibben, an activist who has dedicated his life to saving the planet from environmental collapse, talks about his hopes that Americans will collectively pressure Obama to stand up to big oil. Also included a interview with McKibben and Democracy Now.
The forests stretching from Mexico through Central America have some of the richest species diversity on the planet. But despite expansive conservation efforts, this region continues to face staggering rates of forest destruction
Recent signs that Barack Obama may approve the Keystone XL pipeline have some environmentalists feeling down about the future of the climate. But huge and positive changes are quietly taking place.
Research from the Arctic shows Greenland’s fastest-flowing glacier has doubled its summer flow pace in a decade, and ice cover on Alaskan lakes is declining.
A new study shows that there is at least a 76 percent likelihood that an El Niño event will occur later this year, potentially reshaping global weather patterns for a year or more and raising the odds that 2015 will set a record for the warmest year since instrument records began in the late 19th century.
Painting building roofs white could cool some major cities baking in the intensifying heat of a changing climate. How much benefits white roofs could bring depend on the region of the country they’re installed in and the season, new research shows.
Climate scientists agree that global carbon dioxide emissions need to be sharply cut. A prominent player in the energy industry predicts they will go in the opposite direction.
The head of the World Meteorological Organization tells Climate News Network there is no standstill in global warming, which is on course to continue for generations to come.
by John Michael Greer. First of all, the best way to reduce your ecological footprint isn’t to replace a gasoline-fueled car with an electric car. It’s to replace it with a bicycle, a public transit ticket, or a good pair of shoes. Now, of course, the built geography of much of rural and suburban North America makes it a little challenging to do without a car...
The question of how global warming will influence El Niño has been a challenging one for scientists to answer. A new study suggests while the overall number of El Niños is unlikely to increase, particularly strong “super” El Niños are likely to occur twice as frequently in a warming world.
Farmers may be able to rear livestock which produce fewer emissions from their stomachs of methane, one of the most important greenhouse gases. Stand by for a new breed of farm animal – the low-methane cow
U.S. carbon dioxide emissions related to energy increased in 2013 for the first time in three years, possibly the first sign that a trend in declining emissions from energy consumption has ended for now. The U.S. Energy Information Administration released a report on Monday showing that 2013 energy-related CO2 emissions in the U.S. are expected to have increased 2 percent over 2012 emissions once all the data for the year are tallied.
A corner of the USA forever linked with the name of one of America’s foremost naturalists is changing as the temperature rises. Walden Pond’s familiar vegetation is not what it was in Thoreau’s day.
A wildfire exploded outside Los Angeles Thursday as record temperatures spread across California, where drought conditions are escalating as the state comes off its driest year on record.A new update to the U.S. Drought Monitor shows that severe drought, the second-worst drought category, has spread across 62.7 percent of the California as of Tuesday.
East African Agriculture and Climate Change, published by the International Food Policy Research Institute (IFPRI), looks at threats to food supplies in 11 countries in East and Central Africa – Burundi, the Democratic Republic of Congo (DRC), Eritrea, Ethiopia, Kenya, Madagascar, Rwanda, Sudan, South Sudan, Tanzania and Uganda.
The shortfall between what governments say they will do to cut greenhouse gases and what actually needs to be done by 2020 is growing steadily bigger, the UN says.
by Naveena Sadasivam, OnEarth. More than 650,000 marine mammals are killed each year by fishing gear. A U.S. law that could help stop the slaughter isn’t being enforced. If you enjoy a plate of fish sticks or a salmon burger from time to time...
The U.S. may just be climbing out of the freezer, but Australia has been sweating through a major heat wave to start the year. Heat records fell across a large part of the country in the first week of the New Year. The warm weather is currently centered over sparsely populated Western Australia, but it could hit major population centers along the east coast by late next week.
Local legend has it that the Atlantic Ocean begins here, where the Ashley and Cooper rivers come together to form Charleston harbor, overlooked by a city skyline dotted with church steeples and stately old homes.
Most of the many millions of dollars channelled each year to US organisations which deny that climate change is an urgent problem come from sources which cannot be identified.
Record cold temperatures are being recorded across the Midwest and Eastern United States again today as a so-called polar vortex of dense, frigid air has descended as far south as Texas and Florida.
Maggie Fox, Climate Reality Project, joins Thom Hartmann. Global warming is the greatest threat our planet has ever faced. So what are some concrete steps we can take now to stop runaway climate change before its too late?
Far below the surface, the waters of south-east Asia are heating up. A region of the Pacific is now warming at least 15 times faster than at any time in the last 10,000 years. If this finding – so far limited to the depths where the Pacific and Indian Oceans wash into each other – is true for the blue planet as a whole, then the questions of climate change take on a new urgency.
