Extreme weather events over the past decade have increased and were “very likely” caused by manmade global warming, a study in the journal Nature Climate Change stated. Scientists at Germany’s Potsdam Institute for Climate Research used physics, statistical analysis and computer simulations to link extreme rainfall and heat waves to global warming. The link between…
Lack of understanding of environmental issues is an education problem and requires an education solution. So do we need more science education? Not necessarily, because understanding environmental issues requires some familiarity with the social sciences and humanities as well as the natural sciences; it requires a global perspective and also a sense of how the…
Humans hunted Australia’s giant vertebrates to extinction about 40,000 years ago, the latest research published in Science has concluded. The cause of the widespread extinction has provoked much debate, with climate change being one theory. However, scientists studied dung samples from 130,000 and 41,000 years ago, when humans arrived, and concluded hunting and fire were…
Increasing production and declining consumption of oil and gas have unexpectedly brought the United States markedly closer to a goal that has tantalized presidents since Richard Nixon: independence from foreign energy sources, a milestone that could reconfigure American foreign policy, the economy and more. In 2011, the country imported just 45 percent of the liquid…
While plenty of question marks still hang over the prospect of carbon capture and storage, MIT believes it’s ruled out one: the United States, it says, has enough capacity in its deep saline aquifers to store at least a century’s fossil fuel emissions. In the past, estimates of America’s capacity have ranged from enough to…
As the seas rise, so will the costs associated with them. The impact of climate change on oceans alone could cost $2 trillion by the end of the century, according to a report by the Stockholm Environment Institute in Sweden. That figure comes from a scenario in which Earth’s temperature rises 4 °C by 2100,…
Facing an ever-increasing din of background noise from traffic and other human activities, many animals are adapting by changing their behavior or just moving to quitter locales. In turn, noise pollution is altering the landscape of plants and trees, which depend on noise-affected animals to pollinate them and spread their seeds. Some plants do worse…
Illegal logging generates $10-15 billion around the world, according to new analysis from the World Bank. Its report, Justice for Forests, says that most illegal logging operations are run by organized crime, and much of the profit goes to corrupt officials. The bank says that pursuing loggers through the criminal justice system has made a…
The dream of using hydrogen gas as a clean fuel, on a large scale, just got a little bit closer. Chemists have developed a new molecule that can drive chemical reactions to store and release hydrogen under mild temperatures and pressures. No harmful emissions are released when hydrogen is burned; only water and energy are…
Americans are less likely to believe in man-made climate change as economic conditions get tougher, new research shows. Lyle Scruggs, associate professor of political science at the University of Connecticut, says the public’s belief in climate change dropped significantly as the economy dipped and unemployment climbed in the late 2000s. And the suddenness and timing…
