UK air quality shows little improvement over past 20 years, says study

| 08/30/2016 There has been little improvement in air quality over the past 20 years as transport planners focus on preventing road deaths, according to a study. Two university academics set out to try to understand why there has been little improvement in air pollution concentrations from road transport since the UK signed up to international air quality standards in 1995, as part of the … Continue reading UK air quality shows little improvement over past 20 years, says study

Global warming is melting the Greenland Ice Sheet, fast

| 08/27/2016 A new study measures the loss of ice from one of world’s largest ice sheets. They find an ice loss that has accelerated in the past few years, and their measurements confirm prior estimates. As humans emit heat-trapping gases, we expect to see changes to the Earth. One obvious change to be on the lookout for is melting ice. This includes ice atop … Continue reading Global warming is melting the Greenland Ice Sheet, fast

Human-induced climate change began earlier than previously though

| 08/25/2016 Continents and oceans in the northern hemisphere began to warm with industrial-era fossil fuel emissions nearly 200 years ago, pushing back the origins of human induced climate change to the mid-19th century. The first signs of warming from the rise in greenhouse gases which came hand-in-hand with the Industrial Revolution appear as early as 1830 in the tropical oceans and the Arctic, meaning … Continue reading Human-induced climate change began earlier than previously though

Study measures methane discharge from Arctic permafrost

| 08/25/2016 The project, led by UAF researcher Katey Walter Anthony, studied lakes in Alaska, Canada, Sweden and Siberia where permafrost thaw surrounding lakes led to lake shoreline expansion during the past 60 years. Using historical aerial photo analysis, soil and methane sampling, and radiocarbon dating, the project quantified for the first time the strength of the present-day permafrost carbon feedback to climate warming. Although … Continue reading Study measures methane discharge from Arctic permafrost

Deforestation brought on decreased precipitation in Ganga Basin, NE India

Deforestation brought on decreased precipitation in Ganga Basin, NE India | 08/24/2016 Using satellite data and regional climate models, IIT Bombay researchers have found that deforestation (converting woody savannah to crop land) in northeast India and north-central India has led to a 100-200 mm reduction in summer monsoon rainfall in these two regions. The land use information is based on satellite data for two time … Continue reading Deforestation brought on decreased precipitation in Ganga Basin, NE India

New bits of knowledge into the relationship amongst erosion and tectonics in the Himalayas

New bits of knowledge into the relationship amongst erosion and tectonics in the Himalayas | 08/24/2016 Earth’s climate interacts with so called surface processes — such as landslides or river erosion — and tectonics to shape the landscape that we see. In some regions, the sheer force of these processes has led scientists to believe that they may even influence the development of tectonics. An … Continue reading New bits of knowledge into the relationship amongst erosion and tectonics in the Himalayas

Off South Africa s coast, great white sharks are threatened

Off South Africa s coast, great white sharks are threatened | 08/23/2016 On the edge of a boat off this coastal village, Michael Rutzen stubs his cigarette into a soda can and stares pensively out to sea. Extensive research by Rutzen and his marine biologist partner, Sara Andreotti, has found that great whites off the South African coast are rapidly heading for extinction. The area … Continue reading Off South Africa s coast, great white sharks are threatened

Scotland’s wind turbines cover all its electricity needs for a day

Scotland’s wind turbines cover all its electricity needs for a day | 08/21/2016 High winds on Sunday were strong enough to power the equivalent of all of Scotland’s electricity needs for the day, according to environmentalists. The Met Office issued a yellow “be aware” weather warning covering much of the country as wind speeds reached 115mph on the top of the Cairngorms and gusts of … Continue reading Scotland’s wind turbines cover all its electricity needs for a day
