We are living in the Anthropocene, an era being defined by global mass extinctions caused by humanity. While on-going and impending extinctions of birds and other terrestrial vertebrates gain the most attention, the situation with freshwater fishes (and other freshwater organisms) is as bad or worse, partly because many freshwater extinctions are nearly invisible events, hidden by murky waters (Moyle and Leidy 2023).
Amid a backdrop of extreme weather events and devastating wildfires, federal and international officials this week issued dire warnings about record-setting temperatures and the worsening effects of climate change.
Last month was the planet’s warmest August on record, and the Northern Hemisphere experienced its hottest meteorological summer, the National Oceanic and Atmospheric Administration announced Thursday.
“Global marine heat waves and a growing El Niño are driving additional warming this year, but as long as emissions continue driving a steady march of background warming, we expect further records to be broken in the years to come,” read a statement from NOAA chief scientist Sarah Kapnick.
California is looking to boost water supply and considering new regulations to recycling wastewater straight to your tap. Some refer to it as toilet to tap, however experts in the field say this phrase is anything but accurate.
“It never has been toilet to tap. That has never happened,” said Andrew Salveson, the Carollo Water Reuse Chief Technologist.
San Diego is holding four special elections on Tuesday, Nov. 7, 2023. Understanding the “who, what, where when and how” of voting can be daunting. KPBS researched answers to frequently asked voter questions.
Voters will weigh in on four special elections in different parts of the County. Only those who live in the County’s Fourth Supervisorial District, the city of Chula Vista or in Fallbrook and Rainbow’s districts are eligible to vote in the special election.
In the county’s Fourth Supervisorial District voters will decide on who will fill the seat vacated by former Supervisor Nathan Fletcher and make the final choice among the top two vote-getters in the special general election — voting for either Monica Montgomery Steppe, a Democrat, attorney, and San Diego City Council president pro tem or Republican Amy Reichert, founder of ReOpen San Diego.
Voters in the city of Chula Vista will vote to fill the vacant City Attorney seat. This term expires in December 2026. Candidates include Bart Miesfeld, who served as a city attorney for Chula Vista in the past, Dan Smith Diaz, an attorney, and Marco Verdugo, also an attorney with Burke, Williams & Sorensen.
In Fallbrook and Rainbow voters will weigh in on whether the Fallbrook Public Utility District and the Rainbow Municipal Water District should detach from the San Diego County Water Authority and join the Eastern Municipal Water District.

Imperial County’s largest farming family has lost again in its years-long bid to gain control of valuable Colorado River water allocations associated with its land.
The Imperial Irrigation District on Tuesday won a motion to dismiss a case by Mike Abatti and several relatives, close friends and business associates that closely mirrored an ultimately unsuccessful series of cases they had brought all the way to the U.S. Supreme Court, which declined to hear their petition in 2021.
The Biden administration is restoring significant state and tribal authority over water resources and expanding their leverage on infrastructure permitting decisions, including for pipelines.
With a final rule announced Thursday, EPA reversed Trump-era limitations on state permit approvals, a move the agency said would bolster state and tribal abilities to protect their waters. In addition to restoring certain oversight powers, the move also gives states, tribes and territories a direct role in determining the duration of review processes.
EPA Administrator Michael Regan said in a statement that the rule would support “economically secure, healthy, and sustainable communities” and foster the relationship between the federal government and its lower-level partners.
Pumped storage hydropower is the greenest renewable energy technology for large-scale energy storage, a new study suggests.
Researchers with the National Renewable Energy Laboratory said closed-loop pumped storage hydropower will have a lower carbon footprint throughout the lifecycle of the technology, from construction to decommissioning, than other renewable energy storage technologies like lithium-ion batteries. Portland Business Journal first reported the study.
Closed-looped pumped storage hydropower uses two water reservoirs located at different elevations, one higher than the other, that generate power as water flows or gets pumped, from one reservoir to another. Closed-looped pumped storage hydropower is not connected to continuously naturally flowing water sources.
As the nation continues to push forward to reduce greenhouse gas emissions and transition from using fossil fuels to limit the effects of climate change, storing renewable energy in batteries or pumped storage hydropower has come up as a possible solution for creating cleaner energy at a large scale. Other grid-scale technologies have proven difficult to create, from gathering essential minerals to finding an area large enough to place these technologies. Researchers said closed-looped pumped storage hydropower could be the answer.
A wide-ranging bill at the State Capitol aimed at boosting renewable energy sources includes a provision that could help develop a proposed pumped hydroelectric facility at the San Vicente Reservoir near Lakeside.
Assembly Bill 1373 aims to make the state a centralized buyer for renewable energy sources such as offshore wind power and geothermal facilities. And in a late addition to the bill, it allows the state’s Department of Water Resources to procure funding for a pumped hydro project that “does not exceed 500 megawatts and has been directly appropriated funding by the state before January 1, 2023.”
The Union-Tribune received confirmation from legislative sources that the provision specifically refers to the San Vicente project.
Earth is exceeding its “safe operating space for humanity” in six of nine key measurements of its health, and two of the remaining three are headed in the wrong direction, a new study said.
Earth’s climate, biodiversity, land, freshwater, nutrient pollution and “novel” chemicals (human-made compounds like microplastics and nuclear waste) are all out of whack, a group of international scientists said in Wednesday’s journal Science Advances. Only the acidity of the oceans, the health of the air and the ozone layer are within the boundaries considered safe, and both ocean and air pollution are heading in the wrong direction, the study said.
“We are in very bad shape,” said study co-author Johan Rockstrom, director of the Potsdam Institute for Climate Impact Research in Germany. “We show in this analysis that the planet is losing resilience and the patient is sick.”
It wasn’t too bad of a summer season here in Northern California and really, when it comes to temperature, the entire state of California had a pretty mild summer.
Perhaps Kaitlyn Trudeau, a meteorologist with Climate Central, summed it up best: “Well, it wasn’t as hot as it’s been in recent years.”
