Off the coast of southeastern China, one particular fish species is booming: the oddly named Bombay duck, a long, slim fish with a distinctive, gaping jaw and a texture like jelly. When research ships trawl the seafloor off that coast, they now catch upwards of 440 pounds of the gelatinous fish per hour — a more than tenfold increase over a decade ago. “It’s monstrous,” says University of British Columbia fisheries researcher Daniel Pauly of the explosion in numbers. The reason for this mass invasion,…Source: Grist, a beacon in the smog,an independent news outlet and network of innovators working toward a planet that doesn’t burn and a future that doesn’t suck

Earlier in the day, delegates in Committee A agreed…Source: WHO News
Plastic bottles found to harm human health at every stage of their life cycle
In 1973, a DuPont engineer named Nathaniel Wyeth patented the PET plastic bottle — an innovative and durable alternative to glass. Since then, production has skyrocketed to more than half a trillion bottles per year, driven by beverage companies like Coca-Cola, PepsiCo, and Nestlé. It’s no secret that most of these PET bottles, named for the polyethylene terephthalate plastic they’re made of, are never recycled. Many end up on beaches or in waterways, where they degrade into unsightly plastic shards and fragments that threaten marine life. But blighted beaches are only the tip of the iceberg. According to a new report from…Source: Grist, a beacon in the smog,an independent news outlet and network of innovators working toward a planet that doesn’t burn and a future that doesn’t suck

Two NASA Studies Find Lower Methane Emissions in Los Angeles Region
Researchers found that emissions of the powerful greenhouse gas dropped for several years near the nation’s second-largest metropolitan area.
VISIONS: The EMIT Open Data Portal Two recent studies by researchers at NASA’s Jet Propulsion Laboratory in Southern California used contrasting approaches to measure drops in human-caused emissions of the potent greenhouse gas methane in recent years in the Los Angeles region. In the first study, published in February in Environmental Research Letters, scientists analyzed data from ground-based sensors scattered…Source: NASA’s Global Climate Change – Vital Signs of The Planet
CMMS calibration module or dedicated calibration software?
When your computerized maintenance management system (CMMS) already has a calibration module, why would you buy dedicated calibration software? Itâs a fair question and one that we frequently get asked! The reasons can vary, depending on the application. Are you maybe comparing apples to oranges? There are different kinds of dedicated calibration software products out there, each with somewhat different functionalities. Although they have the same name, they are all different in one way or another. Does integrating dedicated calibration software…
A Global Biodiversity Crisis: How NASA Satellites Help Track Changes to Life on Earth
Climate change plays an increasing role in the global decline of biodiversity—the variety of life on Earth. Scientists use NASA data to track ecosystem changes and to develop tools for conserving life on land, in our ocean, and in freshwater ecosystems.
Many of us associate the sound of a singing bird with the beauty of nature. In recent years, though, fewer chirps, tweets, and birdsong have been heard. It isn’t because birds have stopped singing, but because there are fewer…Source: NASA’s Global Climate Change – Vital Signs of The Planet
Using a Low-Pass Filter to Clean Up Noisy Signals
Often, you’ll need to acquire signals at very high sample rates. Higher sample rates allow you to capture voltage transients, or events that occur in a very short period of time. And since all channels in WinDaq are sampled at the same rate, you might get the results you’re looking for on some channels, and Read MoreSource: DATAQ…

Climate change is increasing the risk of a California megaflood
This is a re-post from Yale Climate Connections by Jeff Masters
A sequence of nine atmospheric rivers hammered California during a three-week period in January 2023, bringing over 700 landslides, power outages affecting more than 500,000 people, and heavy rains that triggered flooding and levee breaches. On a statewide basis, about 11 inches of rain fell; 20 deaths were blamed on the weather, with damages estimated at over $1 billion.
But the storm damages were a pale shadow of the havoc a true California megaflood would wreak.
The Golden State has a long history of cataclysmic floods, which have occurred about every 200 to 400 years — most recently in the Great Flood of 1861-62. And a future warmer climate will likely significantly increase the risk of even more extreme floods. In particular, a 2022 study found that, relative to a century ago, climate change has already doubled the risk of a present-day megastorm, and more than tripled the risk of a trillion-dollar megaflood of the type that could swamp the Central Valley.
Given the increased risk, it is more likely than not that many of you reading this will see a California megaflood costing tens of billions in your lifetime.
This is the third part of a three-part series on California’s vulnerability to a megaflood. Part One examined the results of a 2011 study introducing the potential impacts of a scenario, known as “ARkStorm,” which would be a repeat of California’s Great Flood of 1861-62 — though the study did not take climate change into account. Part Two looked at how California is preparing its dams for future great floods. Here, in Part Three, we’ll look at the increasing future threat of a California megaflood in a warming climate.
