Climate: Heatwaves and drought are piling up

High temperatures and a lack of rain spread serious drought conditions across Europe this summer.

Study tracks increase in extreme conditions

Staff Report

FRISCO — Scientists taking a close look at the last 50 years — the modern global warming era — found that droughts and heat waves are happening simultaneously much more frequently than in the past.

The climate experts at the University of California, Irvine analyzed data  gathered from ground sensors and gauges since 1960 and crunched the numbers with a statistical model to track the upswing.

 

“Heat waves can kill people and crops while worsening air quality, and droughts exacerbate those serious impacts,” said senior author Amir AghaKouchak, assistant professor of civil & environmental engineering. “With these two extremes happening at the same time, the threat is far more significant.” Continue reading

Staff Report

FRISCO — Life has been tough for California’s freshwater fish during the state’s extended drought. But some salmon in the northern part of the state will have a fighting chance after a federal judge last week decided to maintain a key flow program aimed at boosting flows in the Trinity River.

The Trinity is a tributary of the Klamath River, where major salmon runs are currently facing the threat of a major fish kill due to the drought. U.S. Judge Lawrence O’Neill, based on Fresno, California, ruled that the risks from shutting down a federal program to release additional reservoir water to protect the salmon were too great, and the potential benefit to irrigators too uncertain.

Upcoming seminar spotlights regional water issues

CRWCD’s annual water seminar features leading national and regional water and climate experts

Several weekend stories addressed water quailty issues.

Got water?

Staff Report

FRISCO — Colorado this summer may have escaped the severe drought plaguing much of the West — at least for now — but that doesn’t mean the state is immune from regional water woes.

Planners and water users know very well that huge long-term challenges remain for all the states in the Colorado River Basin, and some of those issues will be highlighted during the Colorado River Water Conservation District’s Sept. 10 water seminar in Grand Junction.

Two of the most important women in Western water leadership will be addressing the Colorado River District’s popular Annual Water Seminar in Grand Junction, Colo., that takes place Thursday, Sept. 10, 2015, from 9 a.m. to 3:30 p.m. at the Two Rivers Convention Center. Continue reading

Summer rains keep Colorado mostly drought-free

El Niño projected to bring above average autumn precipitation

Staff Report

FRISCO —Serious drought conditions persisted across the far West in July, but Colorado’s wet spring and summer helped boost the state’s water supplies and stream flow forecasts going into the late summer and fall. Only two small slices of the state have experienced abnormally dry conditions, according to the U.S. Drought Monitor. Continue reading

Study says some forests may not recover from mega-disturbances in the global warming era

Giant fires, insect outbreaks could be ‘game-changer’ for some forests

Staff Report

FRISCO —Forest Service researchers say “mega-disturbances” like giant wildfires and insect outbreaks are likely to hasten the slow demise of temperate forest ecosystems in the coming decades.

Even without those large-scale events, some forests appear to be transitioning to shrublands and steppe, and big disturbances could speed that process, according to a new study published this month in Science. Continue reading

Severe drought spreading across Europe

FRISCO — The western U.S. isn’t the only part of the world experiencing severe drought this year. Across much of central Europe, extremely warm temperatures and lack of rainfall have combined to create the worst drought conditions since 2003.

Hardest hit have been France, Benelux, Germany, Hungary, the Czech Republic, northern Italy and northern Spain, according to new information released by the European Drought Observatory. The report includes data from satellite imagery showing that the areas with the largest rainfall deficits also recorded exceptionally high maximum daily temperatures, in some cases reaching record values.

Staff Report

FRISCO — This year’s wildfire activity in the U.S. has surged to the highest level in 10 years, with the National Interagency Fire Center reporting that about 7.2 million acres have burned so far, and officials said they expect the wildfire season to intensify in the coming weeks.

The drought-stricken far West is hardest hit, with 16 large fires currently burning in Washington, 14 in California and 12 in Oregon. Forest Service Chief Tom Tidwell said federal agencies are currently spending about $150 million per day on fighting fires across the West. Continue reading
