The US and India compete to have the largest solar power field in the world

By Paul Brown

The U.S. Navy is investing in what will be the largest solar farm in the world in order to provide power for 14 of its bases. The climate of Arizona, where the two earlier phases of the Mesquite solar farm are already up and running, provides 300 days of sunshine a year. And the Navy’s deal to extend the farm is the largest purchase of renewable energy ever made by a U.S. federal government agency.

Collaboration at its finest

‘FRESH’ exhibit pairs Boulder County artists and farmers

By Angela K. Evans

“In some ways people that are in local agriculture don’t realize all the stuff going on in local arts or vice versa. There might be people who support local art but don’t realize there is this thriving local food scene,” Guttridge says. “So it makes a lot of sense to join forces and highlight each other and.

The trickle-down effect

‘The Great Divide’ examines the water crisis in Colorado and surrounding states

By Matt Dubois

The American West has always been an arid place, often only supplied with water running down from Colorado. But while the supply chain is the same, mounting population, as well as economic and environmental pressures, have inspired a film with a comprehensive perspective on the water issues in the state.

Local nonprofit Second Mile Water’s second annual Colorado 54 event seeks to end water poverty

By Natalia Bayona

In 2003, while hiking miles through the Himalayas of Southern China, Travis Ramos realized he needed to make a change. He traveled door-to-door through a community of potato farmers known as the Nuosu people, who carve out their homes high on the mountainsides of Yunnan.

Emissions threaten age of uncertainty for carbon dating

New study warns rising CO2 levels will undermine scientific dating of once-living things

By Tim Radford

Climate change driven by increasing levels of atmospheric carbon dioxide will not just damage the health of the planet. A UK scientist now warns that it will also make life increasingly difficult for archaeologists, forensic scientists, art experts, fraud and forgery detectives and people who detect ivory poachers.

Only you can prevent West Nile virus

Recent tests show the virus has arrived across Boulder County

By Mollie Putzig

With a backpack full of specialized bacteria, a force of technicians patrols Boulder-area still waters for miniature pests that can metamorphose into airborne vectors of disease. Acting like the Ghostbusters for mosquitoes, technicians seek out larvae and douse them with a spray of tiny bacteria called Bti — Bacillus thuringiensis israelenis. Bti is derived from naturally occurring soil bacteria and act as a larvicide that kills infantile mosquitoes before they can emerge from their watery breeding grounds.

The new DDT

Activist Jeffrey Smith teams with rocker Neil Young to warn communities about glyphosate

By Mollie Putzig

It’s sprayed on crops, schoolyards, parking lots and possibly your yard. The World Health Organization says it probably causes cancer. It’s the world’s most-used herbicide and the active ingredient in Roundup: glyphosate.

Who’s heard of HERS?

The energy scoring system for homes is complex and inflexible — so why do we use it?

By Christi Turner

Walk onto any car lot and you’ll find every vehicle’s fuel economy rating plastered to its window, just like you’ll see a yellow EnergyGuide tag on every large appliance in any department store. Whether for cars or fridges, these tags showcase simple numbers that communicate long-term costs and savings from energy usage.

Commitment to EnergySmart makes Boulder a national contender in energy efficiency

By Mollie Putzig

If Boulder was big enough to qualify for the list of largest U.S. cities ranked for energy efficiency, it would knock Denver out of the top 10, coming in at No. 7. On the City Energy Scorecard, released in May by the American Council for Energy-Efficient Economy, Boulder outscored Denver by 10 points in building efficiency, earning a total of 69.25 out of 100. Denver came in 10th with 58.5 points.

A picture worth a couple thousand dollars

How drones are changing the image of modern farming

By Emma Murray

Precision agriculture was originally enabled by GPS, allowing farmers to program GPS points into automatic seeders and sprayers so they could micromanage crops — but only after physically surveying the crops, which could take days or even weeks. Using drones, this work can be cut to a matter of hours.

Researchers from the University of Wisconsin Milwaukee tested treatment plants to see what happens to medications after they’re flushed, either by passing through peoples’ systems or dumping of unwanted pills. They found that two drugs — anti-epileptic carbamazepine and antibiotic ofloxacin — came out at higher concentrations than they went in.

The researchers predicted that earlier studies failed to consider other kinds of contributing factors such as extreme weather, water levels and animals. From 1969 to 2012, the university team measured plant productivity at a U.S. Forest Service meadow just outside Bozeman, Montana.

The groups argue that the predictions for Grand Junction and White River BLM districts are grossly underestimating the amount of water that will be required. The new estimate is that each well would require 250,005 gallons of water. However, groups claim water use for horizontal drilling between 2011 and 2014 averaged 3.

This new figure comes from Mark C. Urban of the University of Connecticut, who analyzed 131 published studies on how climate change will affect biodiversity. His investigation showed species in Australia, New Zealand and South America would be worst affected, primarily because there are organisms there found nowhere else on Earth.
