A Los Angeles Times investigation last fall showing as many as half a million barrels of a now-banned pesticide may be sitting on the ocean floor off Catalina Island has led a local assemblyman to propose a new resolution calling on the federal government to take action to protect the island’s ecosystem.

The resolution, AJR 2, authored by Assemblyman Patrick O’Donnell, D-Long Beach, does not specify what action exactly should be taken regarding the toxic waste, nor is any specific funding attached.
The chemical DDT, or dichloro-diphenyl-trichloroethane, has long been known as a cause of a host of environmental problems: sea lions have contracted an aggressive cancer, brown pelicans’ and California condors’ eggshells have thinned, and a significant accumulation of the chemical has been found in bottlenose dolphins.

Woods Hole, Mass. (May 12, 2021) Low-to-mid latitude land surfaces at low elevation cooled on average by 5.8 ± 0.6 degrees C during the Last Glacial Maximum (LGM), based on an analysis of noble gases dissolved in groundwater, according to a new study published in
Nature.
Temperature estimates in the study are substantially lower than indicated by some notable marine and low-elevation terrestrial studies that have relied on various proxies to reconstruct past temperatures during the LGM, a period about 20,000 years ago that represents the most recent extended period of globally stable climate that was substantially cooler than present.
People around the world can check out the livestream of Edna and Ozzie. Author: Neda Iranpour (Reporter) Updated: 12:13 PM PDT May 11, 2021
SAN DIEGO A new livestream, from the Scripps Pier at UC San Diego, is attracting more eyes around the world as it shares the unique ways of birds of prey that call San Diego home.
Edna and Ozzie can be seen on the live streaming cam which overlooks their nest hanging over the Pacific Ocean at La Jolla Shores. You may see Ozzie bring fish that he grabs from the ocean with his talons. He usually eats the fish first then shares what he doesn’t want with Edna who waits and watches.

SAN DIEGO – It is unsurprising that even two years after his death, Walter Munk, who is known as the “Einstein of the Oceans” is continuing to make waves.

With a UC San Diego expert forecasting flooding in La Jolla with nearly every high tide by the end of the century, San Diego City Councilman Joe LaCava said battling climate change, and specifically local sea-level rise, will take an approach combining “science, collaboration and grassroots advocacy.”
LaCava, whose District 1 includes La Jolla, presented a webinar May 3 titled “Sea Level Rise: Reason & Resilience.” Three local experts weighed in on the issue, describing its impacts and how communities can participate in the fight against it.
Mark Merrifield, director of the Center for Climate Change Impacts and Adaptation at UCSD’s Scripps Institution of Oceanography, said the problem is driven by the increase of carbon dioxide in the atmosphere, which has resulted in an “unprecedented” increase in global surface temperature.
