Does climate change have an effect on pregnancy and infant health?
Research in Africa suggests drought and heatwaves results in lower birth weight
A complex statistical analysis of health and climate data suggests there may be a link between climate change and birth weight, at least in parts of the developing world. The findings show that a pregnant woman’s exposure to reduced precipitation and an increased number of very hot days results in lower birth weight.
The two-year research project was led by University of Utah geography professor Kathryn Grace, who said the results are a clear warning that climate change may have a direct affect on public health. Continue reading

Colorado recorded the greatest increase in average maximum temperatures — between .7 and .9 degrees — from the old normals, compiled between 1971 and 2000, and the new normals, which are based on temperature readings between 1981 and 2010. On average across the U.S., the new average temperatures are about .5 degrees warmer.
Multiple state agencies will eye adaptation, mitigation strategies
Colorado’s new climate plan calls for an all-hands-on-deck approach, with various state agencies working together, and with the public, to address the potential impacts of rising temperatures.
Acknowledging that average temperatures in the state could rise by as much as 2.5 to 5 degrees Celsius in the next few decades, Gov. John Hickenlooper called on Colorado make preparations now.
“Colorado is facing a potential increase in both the number and severity of extreme weather events,” Hickenlooper said in a prepared statement. “We’ve seen what Mother Nature can do, and additional risks present a considerable set of challenges for the state, our residents, and our way of life. This comprehensive plan puts forth our commitment from the state and sets the groundwork for the collaboration needed to make sure Colorado is prepared.”

Current drought offers window into future climate conditions.
‘More years like 2015 do not bode well for the frogs …’
LINZ — This year’s fierce drought in the Pacific Northwest has given researchers a chance to see how climate change may affect the region long-term, and the outlook is not good for amphibians.
The low winter snowpack and long, hot summer have left some frogs high and dry as their mountain ponds dry up and disappear. Those conditions could be the norm in another 50 years, said Se-Yeun Lee, research scientist at University of Washington’s Climate Impacts Group and one of the lead authors of the study published last week in PLOS ONE.
“This year is an analog for the 2070s in terms of the conditions of the ponds in response to climate,” said Se-Yeun Lee, research scientist at University of Washington’s Climate Impacts Group and one of the lead authors of the study. Continue reading

High temperatures and a lack of rain spread serious drought conditions across Europe this summer.
Study tracks increase in extreme conditions
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

Latest water skirmish ends with win for fish

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.

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

El Niño projected to bring above average autumn precipitation
Spring and summer rains helped make up for a winter snowfall deficit in Colorado, where statewide precipitation was 98 percent of average 10 months into the 2015 water year. Graph courtesy NRCS.
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
