6 valuable fish stocks removed from overfishing list, according to annual fisheries report

Staff Report

FRISCO — Federal biologists said they’re making progress rebuilding important fisheries, including valuable species like bluefin tuna in the western Atlantic, which along with five other species, was removed from the “overfishing” list.

Overall, the number of domestic fish stocks listed as overfished or subject to overfishing has dropped to an all-time low since 1997, according to a report released in mid-April by NOAA’s National Marine Fisheries Service. Continue reading

Morning Photo: Painting with a camera

Best and brightest


FRISCO —A quick Saturday morning set culled from the archives shows how a camera can be much more than a simple recording instrument. In the right hands — and with the right light — it’s a creative tool as powerful as any palette of paint.

Antarctica meltdown likely to speed up soon

Natural variability still the key driver for East Antarctica temps

Staff Report

FRISCO — A lack of widespread data from Antarctica means it’s still challenging to differentiate human-driven global warming from natural temperature variations in the region, German scientists said in a new study.

Climate researchers need to understand temperature trends in Antarctica to better predict how fast the ice will melt and raise global sea level. But the study concluded that the uncertainties in the temperature trends over Antarctica are larger than previously estimated. Continue reading

After dropping for a few years, U.S. greenhouse gas emissions creep up again in latest EPA tally

Carbon dioxide … and more.

Can the EPA’s clean power plan help tame the global warming dragon?

Staff Report

FRISCO — U.S. greenhouse gas emissions have dropped 9 percent in the last 10 years, the EPA said this week, releasing its 20th annual national greenhouse gas inventory.

The latest tally is current through 2013, which shows a 2 percent increase from the previous year, due to increased energy consumption across all economic sectors and increased use of coal for electricity generation. Continue reading

Colorado River managers downgrade flow projections

Lake Powell expected to see about half of average inflow

FRISCO — Federal water managers downgraded their expectations for Upper Colorado River flows by several notches in the past few weeks, as warm and dry early spring conditions across most of the basin nibbled away at the mountain snowpack that sustains the river’s flows through the summer.

The Bureau of Reclamation today said they expect inflows into Lake Powell to be just 3.75 million acre feet during the key April to July runoff season. That’s just 52 percent of the 1980-2010 average and down 1.35 million acre feet from the projections of just a month ago, when the agency was hoping for 5.1 million acre feet of runoff.

Staff Report

FRISCO — More than 90 percent of the Earth’s land surface experienced warmer than average temperatures last month, which ended up being the warmest March on record for the planet as a whole.

The combined land- and ocean surface temperature was 1.53 degrees Fahrenheit above the 20th century average, breaking the previous 2010 record by 0.09 degrees Fahrenheit, according to the latest global State of the Climate update from NOAA’s National Climatic Data Center. Continue reading

Morning photo: All kinds of blue …

The cool side of the spectrum

FRISCO — Blue is one of my favorite colors, but when it comes to photography, it can be an annoyance. Recently, we had a string of twilights when partially overcast skies predominated. Other than a few splashes of warm colors in the vicinity of the setting sun, the general theme was blue, heightened by the way digital cameras pick up that end of the light spectrum. So rather than fighting it, I decided to go with it in this set, featuring those cool tones in a set of shots all taken along Dillon Reservoir.
