Is western drought the new climate normal?
New study quantifies global warming effect on California drought
FRISCO — Researchers say there’s new evidence that global warming will push the western U.S. into the driest conditions in at least the past 1,000 years, as higher temperatures exacerbate drought condition in the region.
The new study by scientists with Columbia University’s Lamont-Doherty Earth Observatory and Cornell University focused on the current California drought, showing that warmer temps drive moisture from plants and soil into the air. Warmer temps likely worsened the California drought by 25 percent, the scientists concluded in their paper, published in the journal Geophysical Research Letters. Continue reading

The steady drop in Lake Mead’s water level is a sign of the West’s long-term drought.
Some states may see water cuts in years ahead
FRISCO — Early summer runoff is surging high in the headwaters of the Colorado River, but far below, in the Nevada desert, the water is draining out of Lake Mead faster than the river can replenish it.
The giant reservoir this week hit a new all-time low level, dropping just below 1,075 feet above sea level — a warning sign that some states may have to curtail their use of Colorado River water in the years ahead. Continue reading

In March, record cold readings outnumbered record highs by five to one

FRISCO — Federal climate experts this week confirmed what a lot of people already knew instinctively — a long, cold winter stretched well into March in many parts of the country, with the average monthly temperature for the month coming in at 1 degree Fahrenheit below the 20th century average.
Across the country, there were five times as many record cold daily maximum and minimum temperatures (5822) as record warm daily maximum and minimum temperatures (1149) — an anomaly in an era when warm temperature records have consistently outnumbered cold records for months and years at a time.
