In just two years following a man-made flood in the Colorado River Delta, cottonwoods and willows have grown 10 feet tall, rebuilding habitat for other native plants and animals, according to a new monitoring report on the international experiment to re-water the long-arched region.
Soil moisture, snowpack data help inform new forecast modeling
Some droughts creep up on you, while others seem to come out of nowhere, like in 2012 when spring came early and a hot, dry summer parched fields and forests and led to a busy wildfire season, including the destructive Waldo Canyon blaze near Colorado Springs.
Seasonal forecasts issued in May 2012 did not foresee a drought forming in the country’s midsection. But by the end of August, the drought had spread across the Midwest, parching Oklahoma, Kansas, Nebraska, and Missouri. Now, after analyzing conditions leading up to the drough, researchers at the National Center for Atmospheric Research, say similar droughts in the future could be predicted by paying close attention to key indicators like snowmelt and soil moisture.

*Author’s note -this essay was originally published Feb. 26, 2007 on New West.
It’s a mid-winter meltdown here in the Colorado High Country. After a string of seemingly endless powder days that lasted through most of January and the early part of February, the sun is out, the roadside berms are melting. And – shhhhh, don’t tell anyone – despite ski reports touting packed powder, the snow is transitioning at our local ski areas, even turning to (Gasp!) hardpack in places.
None of that stops my friend Dave from making the annual 1,000-mile trek from his home near Lodi, California, where he grows grapes and makes wine when he’s not busy as a volunteer patroller at Heavenly Valley. After all, it’s not just about the snow, it’s about a 20-year ski friendship born on the slopes, a bond that’s in part sustained by our mutual passion for sliding down snow-covered mountains.

Heat-trapping greenhouse gases may dessicate Colorado River Basin
It’s very likely the southwestern U.S. will be hit by droughts unlike any seen since the region was settled by Europeans. Global warming has driven the odds of a 10-year drought to at least 50 percent, and the chances of a 35-year megadrought range from 20 to 50 percent during the next century, according to a new study led by researchers with Cornell, the University of Arizona and the U.S. Geological Survey.
A federal judge in Montana has once again ruled that the U.S. Fish and Wildlife Service violated the Endangered Species Act when it excluded Colorado from a critical habitat designation for threatened lynx. In the end, the rare cat may yet get some protected sanctuaries in the Colorado high county.
Findings can help oil and gas operators minimize seismic risks
For nine months, oil and gas companies pumped 250,000 barrels of industrial wastewater deep underground in the fossil fuel sacrifice zone around Greeley, Colorado — and then, the Earth burped.
On the last day of May, 2014, the wastewater triggered a magnitude 3.2 earthquake that for some area residents felt like a truck hitting their house. The quake was the first in the area in about 40 years, fitting a regional pattern of earthquakes linked with fracking.
Now, a new study by scientists with the U.S. Geological Survey and the University of Colorado shows it may be possible to lessen the risk of frack-quakes by controlling the amount of wastewater being pumped into the ground, and by carefully monitoring seismic activity in fossil fuel development areas.

Draft document highlights global warming threats to state
Colorado Governor John Hickenlooper says a “shifting climate” threatens many of the state’s vital industries, including skiing and agriculture, and he wants the state’s power plants to cut greenhouse gas emissions by 35 percent in the next 15 years from 2012 levels. The goals are outlined in a draft version of an executive order on mitigating and adapting to climate change, which spells out some specific threats of global warming that are already well-known, including:
Greater air pollution will lead to a more hospital admissions and increased cases of respiratory illness;
Changes in precipitation can adversely impact the amount and quality of Colorado’s water resources;
Changes in runoff patterns, intense precipitation, and rising temperatures can negatively affect food production and result in greater risk of food contamination and waterborne illness.
