San Diego Scientist Gets Closer to Understanding Why the Coast Collapses

/in , , /by /Voice of San Diegoby MacKenzie Elmer

Adam Young spent the last three years firing a laser from the back of his truck at Del Mar’s cliffs which are crumbling into the Pacific Ocean.

Cliff collapses along the California coast killed three Encinitas beachgoers in 2019. That same year, another bluff collapse in Del Mar destabilized a set of train tracks regularly carrying passengers between Los Angeles and San Diego. Policymakers need to make big decisions about how best to reckon with earth that seems to fall at random, but scientists still don’t understand what truly causes them to fall.

That’s what Young, a coastal geomorphologist (the study of how the earth’s surface formed and changes) at Scripps Institution of Oceanography, wants to know: If we know how ocean waves and winter rains eat away at a cliff face, can we eventually predict where and when it will collapse?

Southern California Experiences La Niña-Related Dry Spell

Barely any rain and it’s already mid-December? Malibu is experiencing drought conditions—but a drought it is not. That’s a key difference: a “drought” can actually only be declared by the Governor of California; his declaration releases key relief funding for several agencies. “Drought conditions,” on the other hand, is a classification that marks a series of factors that could lead to a drought down the line.

If U.S. Rep. Debra Haaland is confirmed as interior secretary, the Native American from New Mexico could make a huge difference to Arizona and the West when her background and outlook are translated into policy. Experts in Native American affairs and Democratic Party congressional leaders including Rep. Raúl Grijalva of Tucson and Sen. Tom Udall of New Mexico offer predictions for how Haaland’s tenure could affect federal lands and waters: Water rights.

California’s first snow survey of the 2020-21 season is happening Dec. 30 at the Phillips snow course in the Sierra Nevada.

The Department of Water Resources will conduct five of these surveys through May by plunging a long steel tube into the snow. This will measure the snow’s depth and give an estimate of its water content.

Are Marine Heat Waves the New Normal for the Pacific Ocean?

/in , /by /OPB Newsby Cassandra Profita

This year brought one of the biggest marine heat waves on record in the Pacific Ocean, and it’s one of several record-setting spikes in ocean water temperatures over the last six years.

The string of warm water events has scientists wondering if this is actually the new normal for the Pacific Ocean.

A series of heat waves started in 2013 with what was nicknamed “the blob,” which brought water temperatures up to nearly 7 degrees Fahrenheit higher than normal across a 1,000-mile stretch of the West Coast.

The California Department of Water Resources is calling for increased climate change collaboration. DWR is encouraging more cooperation between federal, state, and local governments in their efforts to address climate change. As part of the underlying effort to mitigate the impact of climate change, DWR released the “Moving to Action” plan last month. The move aligns with Governor Gavin Newsom’s goals of addressing natural resource concerns through his executive order to establish a Water Resilience Portfolio.

Scientists Use New Methods to Better Forecast Atmospheric Rivers

/in , /by /Sierra Nevada Allyby Scott King

Earlier this year, the Center for Western Weather and Water Extremes launched a new sub-seasonal to seasonal forecast product to better predict the influence atmospheric rivers will have on the Western United States. Better and more accurate forecasting tools for atmospheric rivers are critical for a number of community uses, including water management, agriculture, insurance and commodities trading, to name a few.

The demand for better atmospheric forecasting tools has facilitated the development of the new S2S forecasting products launched by CW3E this year.

Waves Off Central Coast Contain Clues About Changing Climate. Is California Due for Drought?

/in , /by /San Luis Obispo Tribuneby John Lindsey

The waves along the Central Coast can tell you a lot about our changing climate, and here’s why.

The Diablo Canyon Power Plant’s Waverider Buoy has measured wave heights and periods since June 1983 and directions since June 1996 and is one of the longest continuous-wave monitoring stations along the West Coast.

Scripps Institute of Oceanography’s Coastal Data Information Program maintains an extensive network of buoys that monitor waves along the coastlines of the United States. You can view the historical wave data archive from Diablo Canyon and other stations at the CDIP database at cdip.ucsd.edu.

US: More Must Be Done to Protect Colorado River From Drought

/in , /by /AP News by Felicia Fonseca

A set of guidelines for managing the Colorado River helped several states through a dry spell, but it’s not enough to keep key reservoirs in the American West from plummeting amid persistent drought and climate change, according to a U.S. report released Friday.

Millions of people in seven states and Mexico rely on the river for drinking water and growing crops. The 2007 guidelines were meant to lessen the blow of any future cuts in the water supply for growing areas, giving states an idea of what to expect each year and ways to manage the risks.
