FRISCO — Developing accurate projections for sea level rise has been an elusive, high-priority goal for climate scientists. It’s certain that sea level will keep rising for centuries to come. But it’s not clear at what rate and pace that will happen, especially during the next few decades as coastal communities try to prepare.

Some factors, like thermal ocean expansion, can be established with some accuracy but researchers still aren’t sure exactly how the Greenland and Antarctic ice sheets will respond to warming.

In the latest number-crunching, scientists with the Niels Bohr Institute established that there’s little chance sea level will rise more than 1.8 meters (about 6 feet) by 2100. The results are published in the scientific journal Environmental Research Letters. Continue reading

Environment: $627 million restoration plan finalized to repair some of the damage from the Deepwater Horizon disaster

Barrier islands, shorelines, dunes, underwater grasses and oyster beds targeted for restoration

A NASA satellite image shows the oil slick from the Deepwater Horizon disaster spreading across the northern Gulf of Mexico in late May, 2010.

Staff Report

FRISCO — Nearly four years after BP’s Deepwater Horizon drilling operation disastrously failed and spewed millions of gallons of oil into the Gulf of Mexico, NOAA and its partners have finalized a $627 million restoration plan. The formal record of decision released last week authorizes 44 projects to restore barrier islands, shorelines, dunes, underwater grasses and oyster beds.

This announcement marks the largest suite of Gulf early restoration projects selected thus far in the wake of the 2010 oil spill. The projects aim to address a range of injuries to natural resources and the subsequent loss of recreational use. Details of restoration efforts are outlined in the Final Programmatic and Phase III Early Restoration Plan and Early Restoration Programmatic Environmental Impact Statement. Continue reading

Fish swimming toward poles as fast as they can to escape global warming

Study projects major shifts in species richness patterns

A map from the new University of British Columbia study shows the current distribution of species richness based on data going back to the 1950s.

Staff Report

FRISCO — Many fish species are racing away from the equator and toward the poles to escape steadily warming ocean temperatures. In a worst-case scenario of unchecked greenhouse gas emissions, many fish will disappear from the tropics by 2050, moving poleward by as much as 26 kilometers per decade.

Under the best-case scenario, where the Earth warms by just 1 degree Celsius, fish would move 15 kilometres every decade, according to a new study by scientists with the University of British Columbia study that examined the impact of climate change on fish stocks. Continue reading

Satellites see Four Corners methane ‘hotspot’

Staff Report

FRISCO — The Four Corners region is a methane hotspot, producing the largest concentration of the heat-trapping greenhouse gas methane seen over the United States. Atmospheric concentrations of the gas are more than three times the standard ground-based estimate, according to a new study of satellite data by scientists at NASA and the University of Michigan.

More fracking pollution woes in California

Central Valley groundwater tainted by illegal injections of oil and gas industry wastewater

By Summit Voice

FRISCO — All those warm-n-fuzzy fossil fuel industry ads showing clean-cut techs in lab coats with clipboards may play well on your plasma screen, but reality is a little different.

Rather than being upstanding corporate citizens looking out for the country’s best interests, some energy companies operating in California have been illegally injecting huge quantities of oil and gas wastewater into central California aquifers that supply drinking water and farming irrigation.  Continue reading

Environment: Report warns against unsustainable exploitation of deep ocean resources

Unchecked exploitation of deep ocean resources could have unforeseen impacts, researchers warn.

Planning should include consideration of deep-ocean ecosystem benefits

Staff Report

FRISCO — Scientists are warning against unchecked exploitation of deep ocean resources in the coming decades, saying that the lack of a regulatory framework for areas outside territorial waters opens the door for unsustainable development.

The analysis, published in Biogeosciences, outline the societal benefits of the deep oceans.

“The deep sea is the largest habitat on Earth, it is incredibly important to humans and it is facing a variety of stressors from increased human exploitation to impacts from climate change,” said Andrew Thurber, an Oregon State University marine scientist and lead author on the study. “As we embark upon greater exploitation of this vast environment and start thinking about conserving its resources, it is imperative to know what this habitat already does for us,” Thurber said.

Environment: Pharmaceutical pollutants elude water treatment, make their way into groundwater

This Meadow Creek, a wild, free-flowing stream that starts in the Eagles Nest Wilderness Area and ends up flowing right past our house before its confluence with Dillon Reservoir, where it's wild no more.

Iowa stream sampling shows common drugs turning up in well water

Staff Report

FRISCO — Research in a small stream near Des Moines, Iowa shows how pharmaceuticals and other hard-to-remove pollutants from treated municipal wastewater can travel into shallow groundwater following their release to streams.

“Water level measurements obtained during this study clearly show that stream levels drive daily trends in groundwater levels,” said Paul Bradley, lead author of the new U.S. Geological Survey study. Continue reading
