Odds Of Reaching 100% Of Normal Water Year Precipitation

Drought status is often represented by maps of how much precipitation has fallen in the year to date, or how that amount differs from normal amounts of precipitation to date. Up-to-date examples of such maps are presented below:

A somewhat different viewpoint on the development of drought considers how much precipitation has fallen (or not) and how much is likely to fall in coming months, based on climatology. The following are maps of this and previous years’ drought development that explicitly takes both of these aspects into account.

New Mexico Delegation Takes Aim At US West’s Water Scarcity

As things begin to dry out again in New Mexico, members of the arid state’s congressional delegation are looking for ways to combat water scarcity here and across the American West.

U.S. Sen. Tom Udall is blaming climate change for growing water scarcity. The New Mexico Democrat worries that snowpack in the region is getting smaller and unable to adequately feed the Rio Grande and the rest of the state’s groundwater supplies.

Does A Rain-Free October Signal A Return to Drought In California?

“There are 200 different definitions of drought,” said climatologist Bill Patzert. “If you’re a firefighter with no rain in the month of October, and there are strong Diablo and Santa Ana winds, it’s a drought.”

Southern California got no rain during October, and it was desiccated by super-dry Santa Ana winds.

The jet stream that fed cold air into the Great Basin last week, fueling strong Diablo and Santa Ana winds in California, could have been delivering the first rain storms of the season from the Gulf of Alaska if it had been positioned about 500 miles to the west.

Opinion: A Fresh Look At The Future Of Hydropower Requires That We See Clearly Its Past and Present

As society grapples with climate change and the challenge of decarbonizing the national energy grid, proponents increasingly hold up hydropower as an indispensable part of the solution, touting it as “clean, green energy.” They decry what they see as the unfair federal and state tax and regulatory advantages of wind and solar. In a recent editorial arguing for “a fresh look,” the National Hydropower Association declared that hydropower “isn’t being discussed as a clean energy solution by the environmental community” despite that it is dependable, renewable and “protects and preserves our natural ecosystems.”

In fact, American Rivers and many others in the environmental community acknowledge hydropower’s potential role in a decarbonized energy future, but a fresh look at that potential requires a clear view of hydropower’s past and present.

Drought Here To Stay But Action Can Ease The Pain

Drought is defined by the Bureau of Meteorology as “acute water shortage” (“How bad’s the drought and what’s causing it?”, November 4). It is certainly not going away, and in all likelihood will become more prevalent. Politicians from all sides are realising that a modified Bradfield scheme (diverting monsoonal waters west of the dividing range in Cape York) is the only way to restore the Murray and Australia’s agriculture. Barnaby Joyce and Pauline Hanson are advocating it.

24,000 Pounds Of Trash Removed From San Diego River

More than 100 volunteers removed over 24,000 pounds of trash from the San Diego River on Oct. 26, the second largest watershed management area in San Diego County.

The cleanup came from a comprehensive survey of the lower 20.5 miles of the San Diego River to document trash locations. Over 180 trash sites were identified and mapped in the seven-mile section that volunteers cleaned, which stretches from Dog Beach to Mission Valley.

The San Diego River Park Foundation, who organized the cleanup, said the trash along the river is largely the result of homeless encampments, followed by stormwater debris. San Diego doesn’t treat stormwater, which leads to more pollution.

Carlsbad-Based Seacoast Science Awarded $300,000 by EPA

The U.S. Environmental Protection Agency announced Monday that it awarded $300,000 to Carlsbad-based Seacoast Science Inc. for the company’s efforts to develop environmentally sound technology.

The EPA awarded a total of $2.7 million to nine small businesses in six states, including three in California, as part of its Small Business Innovation Research program. The EPA previously awarded phase one grants of up to $100,000 to small businesses, including San Diego’s 2W iTech LLC, last July. Those recipients were also allowed to apply for the phase two funding announced Monday.
