Oil and water: better monitoring needed to secure vital groundwater supplies, researchers say
Thu, 15 Aug 2019 18:06:27 EDT
When it comes to groundwater quality, fracking receives much of the public attention but misses most of the picture, according to a new study by hydrogeologists.
July 2019 was hottest month on record for the planet
Thu, 15 Aug 2019 13:08:54 EDT
Much of the planet sweltered in unprecedented heat in July, as temperatures soared to new heights in the hottest month ever recorded. The record warmth also shrank Arctic and Antarctic sea ice to historic lows.
Cool roofs can help shield California's cities against heat waves
Wed, 14 Aug 2019 09:38:56 EDT
A new study shows that if every building in California sported 'cool' roofs by 2050, these roofs would help contribute to protecting urbanites from the consequences of dangerous heatwaves.
Fracking prompts global spike in atmospheric methane, study suggests
Wed, 14 Aug 2019 09:06:10 EDT
As methane concentrations increase in the Earth's atmosphere, chemical fingerprints point to a probable source: shale oil and gas, according to new research.
Arctic could be iceless in September if temps increase 2 degrees
Tue, 13 Aug 2019 16:05:26 EDT
Arctic sea ice could disappear completely through September each summer if average global temperatures increase by as little as 2 degrees, according to a new study.
Satellite study reveals that area in Africa emits one billion tonnes of carbon
Tue, 13 Aug 2019 11:22:13 EDT
A vast region of Africa affected by drought and changing land use emits as much carbon dioxide each year as 200 million cars, research suggests.
Human impacts on oceans nearly doubled in recent decade
Tue, 13 Aug 2019 10:19:40 EDT
Over the recent decade, total human impacts to the world's oceans have, on average, nearly doubled and could double again in the next decade without adequate action.
Icebergs delay Southern Hemisphere future warming, study shows
Mon, 12 Aug 2019 17:23:28 EDT
Future warming can accelerate the disintegration of the West Antarctic ice sheet. A large fraction of the ice will enter the Southern Ocean in form of icebergs, which melt and provide a cooling and freshening effect to the warmer and denser ocean water. This process will increase the formation of sea-ice and shift winds and ocean currents. The overall effect is a slowdown in the magnitude of human-induced Southern Hemispheric warming and sea-level rise, according to a new study.
Diet change needed to save vast areas of tropics
Mon, 12 Aug 2019 10:28:53 EDT
One quarter of the world's tropical land could disappear by the end of the century unless meat and dairy consumption falls, researchers have warned.
Low-income, black neighborhoods still hit hard by air pollution
Sat, 10 Aug 2019 09:40:52 EDT
Disease-causing air pollution remains high in pockets of America -- particularly those where many low-income and African-American people live, a disparity highlighted in recent research.
Chicago water pollution may be keeping invasive silver carp out of Great Lakes
Fri, 09 Aug 2019 10:49:39 EDT
Invasive silver carp have been moving north toward the Great Lakes since their accidental release in the 1970s. The large filter-feeding fish, which are known to jump from the water and wallop anglers, threaten aquatic food webs as well as the $7 billion Great Lakes fishery. But, for the past decade, the invading front hasn't moved past Kankakee. A new study suggests that Chicago's water pollution may be a contributing to this lack of movement.
Green turtles eat plastic that looks like their food
Fri, 09 Aug 2019 08:57:31 EDT
Green turtles are more likely to swallow plastic that resembles their natural diet of sea grass, new research suggests.
Back-to-back low snow years will become more common
Thu, 08 Aug 2019 15:25:09 EDT
Consecutive low snow years may become six times more common across the Western United States over the latter half of this century, leading to ecological and economic challenges such as expanded fire seasons and poor snow conditions at ski resorts, according to a new study.
Installing solar panels on agricultural lands maximizes their efficiency
Thu, 08 Aug 2019 12:38:42 EDT
A new study finds that if less than 1% of agricultural land was converted to solar panels, it would be sufficient to fulfill global electric energy demand.
When invasive plants take root, native animals pay the price
Thu, 08 Aug 2019 11:14:27 EDT
Biologists have completed a comprehensive meta-analytic review examining the ecological impacts of invasive plants by exploring how animals -- indigenous and exotic -- respond to these nonnative plants.
