New study shows worrisome signs for Greenland ice | John Abraham
Greenland ice is melting fast, and could potentially cause many meters of sea level rise
As humans put more heat-trapping gases into the atmosphere, like carbon dioxide, ice around the planet melts. This melting can be a problem, particularly if the melting ice starts its life on land. That’s because the melt water flows into the oceans, contributing to rising sea levels. Right now there are three main reasons that sea levels are rising. First, as ocean waters heat, they expand. Second, melting of ice in Antarctica flows into the ocean. Third, melting of ice on Greenland flows into the ocean. There is other melting, like mountain glaciers, but they are minor factors.
Okay, so how much is melting of Greenland contributing to sea level rise? Estimates are that about 270 gigatons of water per year are melting. The melting of an ice sheet like that atop Greenland can occur from the surface as air temperatures and sunlight warm the upper layer of ice. It can also occur from the edges as ice shelves collapse and fall into the oceans in large chunks.

Quarantine alert might have prevented white spot disease outbreak, review finds
Federal authorities investigating prawn imports did not tell Biosecurity Queensland about breaches
The white spot virus outbreak that devastated prawn farms in south-east Queensland may have been avoided if federal authorities investigating quarantine failures had warned the state’s biosecurity agency, a review has found.
The damning assessment is contained in the report of a marine biologist, Ben Diggles, who was contracted to investigate the white spot outbreak by the Fisheries Development and Research Centre – a body jointly funded by government and industry.
Tumps of tunnelling moles reveal the past
The Trundle, West Sussex Ramparts’ busy archaeologists send forth iron age pottery, shells and bones as they excavate
As we walked the perimeter of the ramparts, we noticed that the cropped turf-covered contours below were heavily tracked with molehills. We came across an area of fresh tumps, the newly excavated soil still damp and dark like coffee grounds.

Anglers warned to avoid area as authorities and Qantas investigate leak of chemicals classified as an ‘emerging contaminant’
A significant spill of firefighting foam at Brisbane airport has contaminated nearby waterways, killing fish and prompting warnings to recreational anglers.
About 22,000 litres of the foam leaked in a Qantas hangar on Monday, the Queensland government confirmed.

Scott Pruitt hails era of environmental deregulation in speech at coal mine
EPA administrator declared an end to the government’s ‘war’ on coal in a speech to miners – an agenda that has been bitterly opposed by agency staff
Scott Pruitt, the US Environmental Protection Agency (EPA) administrator, heralded a new era of environmental deregulation on Thursday, in a speech at a coal mine that was fined last year for contaminating local waterways with toxic materials.
Pruitt said the new “back to basics” agenda for the EPA would focus on devolving oversight of clean air and water to individual states, and bolstering jobs in industries such as coal, oil and gas.

Hopes that ministers will make special case for Western Isles, Orkney and Shetland after visit by business secretary
Ministers are believed to be on the verge of a U-turn on their manifesto pledge to halt the spread of subsidised onshore windfarms – on remote Scottish islands, at least.
The business secretary, Greg Clark, visited the Isle of Lewis in the Western Isles on Monday to discuss the possibility of government support for turbines off the mainland.

Whale’s eye view reveals feeding habits in Antarctica – video
The World Wildlife Fund released this footage filmed in March 2017 that shows the view from a camera attached to a whale in Antarctica. Scientists used suction cups to attach cameras to humpback and minke whales, revealing new feeding habits and their social lives. The data gathered will be used to protect whales and their ecosystems

Nearly every house in this rural 450-acre development of stargazers is equipped with its own domed observatory, and outdoor lights are strictly forbidden. Does it also hold answers for combatting America’s problem with light pollution?
Take a nighttime drive into Arizona Sky Village, in a remote valley in south-east Arizona, and the only thing you can see clearly are the millions of stars twinkling overhead. Beyond the light show, the sky is a deep inky black, and the ground below is nothing but shadows. Dimmed car headlights might pick up spooked jackrabbits hopping through the desert brush, but the village’s unlit houses are all but invisible in the darkness.
That’s the way the residents of this astronomy-loving community like it. The less light, the better their view of the universe.

How much could commuter cycling increase in your part of England?
New tool maps the potential increase in bike journeys under different scenarios – from routes avoiding hills to adopting e-bikes – revealing health benefits and informing future investment
Chances are you live in a place where less than one in 20 commuters regularly cycle to work. Sometimes people assume this is because England is too hilly, or that most home-to-work distances are too far to cycle. Hilliness and distance do matter. However, new research has found that this is only part of the story. With the right cycling conditions, cycling levels could be much higher than they are now.

First WI report on food waste finds confusion persists over ‘best before’ and ‘sell by’ dates, with supermarkets potentially contributing to the problem
The Women’s Institute is urging supermarkets to do more to help consumers reduce their domestic food waste, after a survey of its own membership revealed widespread confusion about “best before” and “use by” labelling on packaging.
Its new analysis of products on supermarket shelves found that “once-opened” instructions were often contradictory and often failed to make clear whether they were a guide to food safety or quality.
