Study: Swapping beans for beef would put serious dent in greenhouse gas emissions. The US' current plans to combat change include, among other things, a pledge to cut greenhouse gas (GHG) emissions by 17 percent by 2020 relative to 2005 levels.
Whichever way you slice it, that sort of reduction would involve some radical shifts in behavior. A new study has put forth one such suggestion, substituting the entire US population's beef with beans, a dietary change they say would achieve between 50 and 75 percent of this reduction target. Let's get one thing straight, the entire US population is not going to suddenly stop eating beef. You'd struggle to convince the third-generation Texas barbecue pit master to shut up shop, and you're not going to tell a Yankees fan that they can't have a hot dog at the ball game (those things have got beef in them, right?)
Remote island has 'world's worst' plastic rubbish density. Earth - Terrifying 20m-tall 'rogue waves' are actually real. TEN-storey high, near-vertical walls of frothing water.
Smashed portholes and flooded cabins on the upper decks. Thirty-metre behemoths that rise up from nowhere to throw ships about like corks, only to slip back beneath the depths moments later. Evocative descriptions of abnormally large "rogue waves" that appear out of the blue have been shared among sailors for centuries. With little or no hard evidence, and the size of the waves often growing with each telling, there is little surprise that scientists long dismissed them as tall tales. Until around half a century ago, this scepticism chimed with the scientific evidence.
However, we now know that they are no maritime myths. Sciencemag. It is undeniably an ambitious vision.
Boyan Slat, a charismatic 22-year-old drop-out inventor, plans to clean up plastic trash circulating in the North Pacific Gyre by launching a fleet of floating trash collectors. Ocean currents would propel floating plastic trash into curved floating booms, which would funnel trash toward a central tank, to be collected monthly by ships. The ocean cleanup unveils breakthrough new design ready to start work in 2018. The Doomsday Glacier - Rolling Stone. In the farthest reaches of Antarctica, a nightmare scenario of crumbling ice – and rapidly rising seas – could spell disaster for a warming planet.
Thwaites Glacier in West Antarctica is so remote that only 28 human beings have ever set foot on it. Knut Christianson, a 33-year-old glaciologist at the University of Washington, has been there twice. A few years ago, Christianson and a team of seven scientists traveled more than 1,000 miles from McMurdo Station, the main research base in Antarctica, to spend six weeks on Thwaites, traversing along the flat, featureless prairie of snow and ice in six snowmobiles and two Tucker Sno-Cats. "You feel very alone out there," Christianson says. He and his colleagues set up camp at a new spot every few days and drilled holes 300 feet or so into the ice.

They arrive where they're not wanted, spread aggressively, and they damage the very system in which they live.

Theconversation. The Paris Agreement commits nations to limiting global warming to less than 2˚C by the end of the century.
However, it is becoming increasingly apparent that, to meet such a massive challenge, societies will need to do more than simply reduce and limit carbon emissions. It seems likely that large scale removal of greenhouse gases from the atmosphere may be called for: so-called “negative emissions”. One possibility is to use waste material from mining to trap CO₂ into new minerals, locking it out of the atmosphere. For the first time on record, human-caused climate change has rerouted an entire river.
A stream flows through the toe of Kaskawulsh Glacier in Kluane National Park in the Yukon.
In 2016, this channel allowed the glacier’s meltwater to drain in a different direction than normal, resulting in the Slims River water being rerouted to a different river system. (Dan Shugar) A team of scientists on Monday documented what they’re describing as the first case of large-scale river reorganization as a result of human-caused climate change. They found that in mid-2016, the retreat of a very large glacier in Canada’s Yukon territory led to the rerouting of its vast stream of meltwater from one river system to another — cutting down flow to the Yukon’s largest lake, and channeling freshwater to the Pacific Ocean south of Alaska, rather than to the Bering Sea.
The researchers dubbed the reorganization an act of “rapid river piracy,” saying that such events had often occurred in the Earth’s geologic past, but never before, to their knowledge, as a sudden present-day event. Business true. Researchers: Antarctica's sleeping ice giant could be waking soon. Scientists were able to reach the vast floating East Antarctic Totten ice shelf, which provides the backward stress that blocks the ice of the largest glacier in East Antarctica from emptying into the ocean.
They were able to take measurements of the water, the depth and the shape of the bedrock. Jane Qiu writes a compelling post in the journal Nature, where she reports on the scientists and the grim findings that the measurements had revealed below the bitter cold and ice of East Antarctica. Qiu notes the E Antarctic region is about as big as the entire United States and the majority of it is an ice cap sitting on a high plateau 2 ½ miles above the ocean surface. It is an inhospitable environment where temperatures can plunge to −140F. The glaciologists confirmed, that like the West Antarctic ice shelves that buttress their glaciers, the East Antarctica shelves are also melting from beneath due to warm ocean temperatures. 3D image of Antarctica offers clearest picture yet of ice coverage. Since 2010, the European Space Agency's CryoSat satellite has circled the Earth and monitored the state of the polar sea ice, along with the ice sheets that cover Antarctica and Greenland.
Some of the data collected over the last six years has now been compiled into a one-of-a-kind 3D image, offering a more comprehensive look at Antarctic ice elevation than ever before. The 3D image is constructed from around 250 million measurements taken by CryoSat's radar altimeter. Radar altimeters work by bouncing radio waves off the terrain below and measuring how long they take to return to the spacecraft. How To Make Farmers Love Cover Crops? Pay Them. Green shoots of cereal rye, a popular cover crop, emerge in a field where corn was recently harvested in Iowa.
The grass will go dormant in winter, then resume growing in the spring. Less than three percent of corn fields in the state have cover crops.

New research investigating the transition of the Sahara from a lush, green landscape 10,000 years ago to the arid conditions found today, suggests that humans may have played an active role in its desertification. The desertification of the Sahara has long been a target for scientists trying to understand climate and ecological tipping points.
A new paper published in Frontiers in Earth Science by archeologist Dr. David Wright, from Seoul National University, challenges the conclusions of most studies done to date that point to changes in the Earth's orbit or natural changes in vegetation as the major driving forces. "In East Asia there are long established theories of how Neolithic populations changed the landscape so profoundly that monsoons stopped penetrating so far inland," explains Wright, also noting in his paper that evidence of human-driven ecological and climatic change has been documented in Europe, North America and New Zealand.

Back in 2011, the giant Chevron corporation was found guilty of illegally dumping billions of gallons of oil waste into the Ecuadorian rainforest in what has been described as the Amazon’s “Chernobyl” and the worst case of oil pollution on the planet. Chevron was ordered to pay $US 9.5 billion to offset the damage they caused, which they are still dodging with an army exceeding 2,000 lawyers while a huge slice of the most bio-diverse and beautiful ecosystem on earth remains contaminated.

Mutant grasses can clean up the mess left over from bombs. RDX is a highly-toxic explosive that has been used in munitions ever since World War II. To this day, it accumulates in the soil at locations such as bombing ranges and military training grounds, where it can ultimately leech into groundwater sources. Cleaning up these contaminated sites using conventional technology can be very expensive, so scientists at the University of Washington and the University of York have developed an alternative – they've created transgenic grass that "eats" RDX.
