Half of U.S. oil is now fracked – but it might not stay that way
Posted by Grist: None Given on March 28th, 2016
Grist: The U.S. has quickly become a global fracking powerhouse, and it`s not slowing down.
According to a March report from the Energy Information Administration, hydraulic fracturing now accounts for more than half of all U.S. oil output per day, compared with 2 percent in 2000. America`s 300,000 fracking wells pumped out 4.3 million barrels per day in 2015 - a staggering figure when compared to the 102,000 barrels a day in 2000. That growth has allowed the U.S. to "increase its oil production faster...

ScienceDaily: As groundwater levels decline, identifying plants that can thrive in low water conditions is increasingly important. A new study focused on Agave, a species that has the ability to be highly water-use efficient in hot, drought-prone environments. The authors said that Agave, traditionally used as a source of food, beverages, and fiber, has the potential to be cultivated more widely to produce alternative sweeteners, bioenergy, and for other end uses. They said that determining how Agave species respond...
Arctic sea ice extent breaks record low for winter
Posted by Washington Post: Juliet Eilperin on March 28th, 2016
Guardian: A record expanse of Arctic sea never froze over this winter and remained open water as a season of freakishly high temperatures produced deep – and likely irreversible – changes on the far north.
Scientists at the National Snow and Ice Data Centre said on Monday that the sea ice cover attained an average maximum extent of 14.52m sq km (5.607m sq miles) on 24 March, the lowest winter maximum since records began in 1979.
The low beats a record set only last year of 14.54m sq km (5.612m sq miles),...
Aboriginal Groups Trying Halt a Natural Gas Boom in Australia’s Northern Territory
Posted by Vice: Harry Pearl on March 28th, 2016
Vice: Conservationists and indigenous communities in northern Australia are gearing up for a fight, as some of the world's largest energy companies line up to frack the region for shale gas. Santos, Sasol, Inpex and, more recently, businessmen who have made billions from fracking in the United States have all been lured to the McArthur Basin in Australia's Northern Territory. American Energy Partners (AEP), the company established by US fracking pioneer Aubrey McClendon — who died two weeks ago — has...

Conversation: Wine grapes are one of the most valuable horticultural crops in the world, a globally important industry with commercial vineyards on six continents and all 50 U.S. states. Like many crops, these vineyards, and their grapes, are extremely sensitive to temperature and rainfall during the growing season.
Climate and weather can affect the timing of harvest, the amount of fruit produced and even the ultimate quality of the wine. And with warming from human greenhouse gas emissions already manifesting...

Posted by Vox: None Given on March 28th, 2016
Vox: Some of the world's most important farming regions rely on freshwater from large underground aquifers that have filled up slowly over thousands of years. Think of the Central Valley aquifer system in California. Or the Indus basin in Pakistan and India. This groundwater is particularly valuable when rain is scarce or during droughts.
But that groundwater may not last forever. Data from NASA's Grace satellites suggests that 13 of the world's 37 biggest aquifers are being seriously depleted by irrigation...

Posted by Washington Post: Juliet Eilperin on March 28th, 2016
ScienceDaily: Tardigrades, also known as moss piglets or water bears, are eight-legged microscopic animals that have long fascinated scientists for their ability to survive extremes of temperature, pressure, lack of oxygen, and even radiation exposure.
Now, a study has found that, contrary to a previous controversial proposal, tardigrades have not acquired a significant proportion of their DNA from other organisms.
Instead, new analysis from the University of Edinburgh shows that nearly all of what was proposed...

Posted by Denver Channel: Mike Nelson on March 28th, 2016
Denver Channel: Climate change and rising global temperatures are just a natural process that the earth has experienced many times over its long history. What’s not normal right now is the speed at which those temperatures are rising. Professing Scott Denning from Colorado State University joined us on the First Alert Spring Forecast to talk about climate change. He says the greenhouse effect is what keeps the earth inhabitable and that without CO2 in the atmosphere, the earth would be cod enough to freeze the...
