Globally 1.2 billion people live in areas of water scarcity — defined by the United Nations as locations with an annual water supply that drops below 1,000 cubic meters per person.
The secret ingredient in Boston's prize winning tap water? Forest conservation. If you already love Boston for its unmistakable accent and unpredictable baseball team, you might want to consider adding its tap water to your list. Boston came out on top of this year’s tap water taste test, an annual competition hosted by the American Water Works Association
If you’ve ever wondered how much little things really matter, consider the mountain pine beetle. Roughly the size of a grain of rice, the glossy black insect lives only about a year. A throng of beetles can ravage a pine as tall as an eight-story building, as the tree first oozes sap, then its needles turn rusty red...
by Stacie Bland. As a high school student, I have seen environmental apathy everywhere. The basic concept among my peers seemed to be "why worry about it -- we're only here for a short time". I believe this attitude could be severely affected by the child's family.
Dire warnings of imminent human-induced climate disaster are constantly in the news but predictions of the end of the world have been made throughout history and have never yet come true.
Spring and summer have come early – and observations from some parts of the country even suggest that typical autumn events, such as the development of beech nuts and hawthorn berries, are already in evidence. But, to understand effects on our wildlife, a longer view is needed...
About 300 wolves live in the nearly 2-million-acre swath of central Ontario forest known as Algonquin Provincial Park. These wolves are bigger and broader than coyotes, but noticeably smaller than the gray wolves of Yellowstone. So how do they fit into the wolf family tree? Scientists don’t agree on the answer—yet it could now affect the fate of every wolf in the United States.
The UK government’s senior adviser on science has made an entirely sensible call for researchers and policy makers to move the climate change debate towards workable strategies and solutions. The trouble is, the models we have for assessing those strategies are deeply flawed.
Who determines whether chemicals are safe — and why do different governments come up with such different answers? In the United States, children can drink fruit juice beverages made with Red Dye No. 40 and eat macaroni and cheese colored with Yellow Dye No. 5 and No. 6. Yet in the U.K., these artificial colorings have been taken off the market due to health concerns.
“What’s the most effective way to raise awareness of environmental issues and motivate people to take action?” While pondering this question recently, I was reminded of a talk I saw several years ago that still ranks among the most powerful I’ve ever seen.
A guidebook with a difference is selling well in Germany. It details nearly 200 renewable energy sites it thinks will appeal to tourists. Wind turbines and solar panels: do you love them or hate them? Do you think of renewable energy as the way to a greener future, or an awful blight on the present?
The California Fish and Game Commission voted on June 4 to grant endangered species protections to gray wolves. This is the first time the state has stepped into the issue over the species, which is losing protection and being killed in several states, and which is expanding to territories it had not inhabited for decades in others.
Reducing deforestation in the tropics would significantly cut the amount of carbon dioxide emitted into the atmosphere by as much as one-fifth, research shows.
Last month, a researcher at the National Renewable Energy Laboratory in Golden, Colo., loaded a postage stamp–sized solar cell onto a tray and placed it under a high-intensity pulse solar simulator. A new world record for solar photovoltaic efficiency had been set.
The “Meatless Mondays” campaign was originally thought up to support the war effort during World War I, but now a modern army is using it to fight an even bigger battle—the one against climate change. It's not just Norway where the military is concerned about climate change. Former United States army officer...
The heavyweights of the global insurance industry, well aware of the risks posed to their finances by extreme weather events, have made a renewed commitment to use their financial clout and influence to tackle the climate impacts of a warming world
The majority of Americans believe that global warming is real. A fewer number believe that it is a threat and less still believe that it is caused by humans. These are really amazing numbers...
The newly released National Climate Assessment spans 30 chapters with thousands of references on how climate change is impacting the U.S. The report took more than 300 scientists and 4 years to prepare, including addressing more than 4,000 comments from the public. The message of the report is that climate change is already happening across the country.
Scientists in the US have found new ways to make biofuel, increase crop yields and exploit carbon dioxide through novel applications of familiar materials.
Parts of ancient Antarctica were as toasty as today’s California coast, say scientists who used a new method to measure past temperatures. The study focused on Antarctica during the Eocene epoch, 40 to 50 million years ago, a period with high concentrations of atmospheric CO2 and consequently a greenhouse climate.
(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
