Hawaii Officials Rethink Astronomical Observatory Plans

Monitor: There will be no further construction work on Mauna Kea for new astronomical observatories, instead the existing ones will be decommissioned and rebuilt. This is the main decision reached by the University of Hawaii in cooperation with the Department of Land and Natural Resources. Initial plans involved the construction of a new, modern observatory on a newly commissioned site. Following heated protests from the local population, University of Hawaii representatives have decided to rethink their...

Coupled human, natural systems explain change on Mongolian Plateau

ScienceDaily: Human influence on the natural world is widely acknowledged to have reached an unprecedented scale. Likewise, changes in natural systems have the potential to alter human behaviors, creating complex system interactions. These dynamics can be understood using the conceptual framework of coupled human and natural systems, or CHANS. In an article published in the June issue of BioScience, a cross-disciplinary group of researchers, led by Jiquan Chen, of Michigan State University and Nanjing University...

Three Mauna Kea telescopes to go

Associated Press: The University of Hawaii announced a plan Monday that will lead to the removal of several large telescopes on Mauna Kea. School officials will meet with the state Department of Land and Natural Resources this week to discuss the decommissioning process. The plan comes nearly a week after Gov. David Ige said school officials need to do a better job caring for the mountain and asked that they carry out 10 actions. The discussions were sparked by protests against the proposed Thirty Meter Telescope....

Giant telescope Hawaii gets go-ahead, others shut down

New Scientist: One in four must go. Hawaii's giant Thirty Meter Telescope (TMT) is back in business after a hiatus of 2 months - but at the expense of other telescopes. Back in April, construction of the telescope was temporarily halted in the face of mounting protests from native Hawaiians. The telescope would dwarf any observatory now in existence, allowing astronomers to peer to the very edge of the visible universe. Its presence atop the extinct volcano Mauna Kea, however, which many Hawaiians consider sacred...

7 Epic Droughts Devastating the Planet

EcoWatch: Every inhabited continent, to varying degrees, faces extremely high water stress. That means that in certain areas more than 80 percent of the local water supply is withdrawn by businesses, farmers, residents and other consumers every year. Not all of that water is consumed--it may flow back into a river after it’s used and be available again downstream--but the demand still creates competition where it is needed. These “stressed” areas are also the ones most vulnerable to episodic droughts. With...

Canada’s Alberta pledges new climate regulations by month’s end

Reuters: Alberta, the Canadian province whose carbon-intensive oil sands are the largest source U.S. oil imports, said on Tuesday it would have new climate change regulations in place by June 30, when the current rules expire. Shannon Phillips, the environment minister for the province's newly elected left-wing government, said in a statement that her first steps would include energy-efficiency and renewable-energy strategies. The New Democratic Party, which ended 44 years of government by the Conservative...

Exxon CEO says Europe should see climate benefit shale gas

Bloomberg: Exxon Mobil Corp. CEO Rex Tillerson said Europe should see the “tremendous environmental benefits” of producing natural gas from shale, pointing to the U.S. output boom as a model for cutting greenhouse-gas emissions. “Natural gas and shale have been instrumental in reducing CO2 emissions to levels not seen since the 1990s” in the U.S., the chairman and chief executive officer of the Irving, Texas-based company said at the World Gas Conference in Paris Tuesday. “U.S. gas production has soared...

Drought takes $2.7 billion toll California agriculture

Climate Central: The record-breaking drought in California — brought about by a severe lack of precipitation, especially mountain snows — has exacted a $2.7 billion toll on the state’s economy because of agricultural losses, researchers said Tuesday. During a briefing for the California Department of Food & Agriculture, scientists from the University of California, Davis, told officials that based on their preliminary research and modeling, the drought is resulting in a harder economic pinch this year than it was...

Mining towns worry frac sand gifts will dry up with oil price slump

EnergyWire: Since the arrival of a mine that supplies sand to hydraulic fracturing sites in distant shale fields, this tiny township has gained a new dump, recycling center, snowplow and salt shed. Plans for a community garden are underway in a neighborhood across the street from the plant. Perched atop a pair of railroad underpasses, Unimin Corp.'s Tunnel City silica extraction center last year began sending carloads of fine, white sand to energy producers in Pennsylvania, North Dakota and Texas. Under the...
