A San Diego scientist says a surge in outlawed ozone-depleting gasses appears to be easing. Scripps Institution of Oceanography researcher Ray Weiss says levels of chlorofluorocarbons (CFCs) in the atmosphere began rising a few years ago, even though they had been outlawed by the Montreal Protocol. The chemical was once used as a refrigerant and in the manufacture of foam, but CFCs were outlawed more than a decade ago.
Buried in San Diego County’s lagoons are centuries worth of carbon, cached in muddy stockpiles that scientists say could help combat climate change. Recently, scientists with the conservation organization Wildcoast and Scripps Institution of Oceanography started studying how much carbon coastal wetlands can capture, and how to restore these environments to boost that capacity.
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?
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.
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.
California weather is rarely average. Historically, the state has well above or well below average rain and snow. One of the keys to prepare for these wild swings is a better understanding of atmospheric rivers. The Center for Western Weather and Water Extremes or CW3E is at the heart of this research.
At the Center for Western Weather and Water Extremes, researchers feel the urgency as they examine connections between West Coast precipitation and a devastating wildfire season, which has yet to conclude.
Matthew Costa stepped gingerly into a little pocket wetland near the Del Mar Fairgrounds. The squishy salt marsh is more than just a patch of habitat in the intertidal zone. “Just watch out,” said Costa, a postdoctoral researcher at the Scripps Institution of Oceanography, as he warned a helper. “Watch out for birds.” Endangered ridgeway rails like hiding in the pickleweed that covers the soft, moist ground nestled between train tracks and a busy Del Mar street.
San Diego researchers are getting a better understanding of the storm systems that bring the region most of its rain and they are getting that information the old fashion way — from weather balloons. Last March, gray rain-filled skies seemed to dip into the ocean as a storm moved across the region.
The San Diego County Water Authority is partnering with the renowned Scripps Institution of Oceanography at UC San Diego to better predict atmospheric rivers and optimize water management before, during and after California’s ever-changing seasonal storms.
Atmospheric river storms produce 40%-60% of the West Coast’s annual precipitation and are responsible for the majority of flood damage in the region. Predicting and managing this is challenging due to unpredictable and changing snowmelt and rainfall.
To study this, Scripps’ Center for Western Weather and Water Extremes (CW3E) introduced the Water Affiliates Group, which brings together relevant science and water industry expertise to enhance reservoir operations along with California’s changing climate.
