It might be surprising that globally we don’t systematically monitor the health of our rivers. Imagine damming and diverting the arteries in our bodies without taking care to monitor the consequences. Our health would turn precarious, to say the least.
ITHACA, N.Y. – Many birders enjoy playing an imaginary game with one another: “Blindfold me and place me anywhere in the world – I bet I can identify where I am, as long as you let me hear the birds.” This phenomenon exists because most birds are finely tuned to a narrow place on Earth. Every species has developed traits that permit it to cope with the challenges and capitalize on the opportunities of habitat in every biome, whether it’s the windswept Arctic tundra, the Antarctic ice sheets, the fog-shrouded mountaintops or the world’s driest scrubs. From giant ostriches to tiny bee hummingbirds, their ability to populate land and sea the world over is a testament to nearly 200 million years of evolutionary adaptation since diverging from the dinosaurs.
ROCKVILLE, Ind. (WTHI) - A mysterious killer continues to wipe out many of the nation's honey bees. It could have a devastating effect nationwide, and right here in the Wabash Valley. Local farmers are already seeing the effects on a favored fall fruit. On Sunday afternoon Steve Hauser combs through his trees, getting rid of…
This class describes the science of global warming and the forecast for humans’ impact on Earth’s climate. Intended for an audience without much scientific background but a healthy sense of curiosity, the class brings together insights and perspectives from physics, chemistry, biology, earth and atmospheric sciences, and even some economics—all based on a foundation of simple mathematics (algebra).
Smoke emits from the chimneys of numerous brick kilns on the outskirts of New Delhi, India. The world's three biggest carbon polluting nations China, the U.S. and India all saw their emissions jump in 2013.
Coca-Cola is the latest company to join the agricultural 'scramble for Africa', writes Miriam Ross. Backed by £600 million of British aid under the guise of 'food security' and 'nutrition', a vast give-away of Africa's land is under way that will condemn small farmers to landlessness and poverty.
Governments must shift subsidies and research funding from agro-industrial monoculture to small farmers using 'agroecological' methods, according to the UN's Special Rapporteur on the Right to Food. And as Nafeez Ahmed notes, her call coincides with a new agroecology initiative within the UN's Food and Agriculture Organisation.
David Biello reports - The first step in solving the world's forest problem is recognizing the world's forest problem.
Just 25 countries hold almost all of the world's undisturbed forests. More than half of that forest is in Australia, Canada, New Zealand, Russia and the U.S. And only 22 percent of forestland worldwide is protected.
"For at least 70 years, the Red Delicious has dominated apple production in the United States. But since the turn of the 21st century, as the market has filled with competitors—the Gala, the Fuji, the Honeycrisp—its lead has been narrowing. Annual output has plunged."
Dozens of companies, non-profit organizations, and governments pledged to work together to halve forest loss by 2020 and end it altogether by 2030. If implemented, the commitment could reduce annual carbon dioxide emissions by 4.5-8.8 billion tons annually, equivalent to removing a billion cars from the world's roads.
Crackling heat and thick billowing smoke raced across the landscape. After weeks of scorching dry summer weather, the wildfire seemed to hungrily consume the earth. In northern Alberta, Canada, the Richardson fire of 2011 gained particular notoriety for ravaging nearly 700,000 hectares – and threatening the Athabasca oil sand development. Yet it is these very wildfires that are so crucial in shaping our boreal forests – which make up nearly one third of the world's forests.
