I looked at the #grokipedia articles about five major environmental topics: coral reefs, sea ice, Amazon rainforest, wildfire, glacier. The five articles mentioned the phrases climate change/global warming a total of 4 times. They said alarm/alarmism/alarmist 12 times. 🧪🌿🌎

We can protect California's forests from megafires. Last month, I visited part of the Sierra Nevada that burned in 2021. In unmanaged areas, most trees died. But where land managers had thinned trees and conducted prescribed burns, nearly every tree survived. These photos show the difference.🧪🌿🌎

Oak‑savanna birds thrive after fire, a new study found. Dozens of species preferred areas that burned in the 2018 Mendocino Complex Fire over unburned areas. So far, these ecosystems are proving resilient to increasingly severe wildfires, the authors concluded. 🧪🌿🌎

‪This was a fun story to write. Last year, environmental police in Brazil stumbled upon thousands of climbing bumblebee catfish. Scientists know almost nothing about this species, which only became known to science in 2017. 🧪🌿🌎

Whether it’s ice cream, a greasy hamburger, or a heap of french fries, everybody loves fatty foods. For coyotes, that meal is a blubbery seal pup, according to a new study led by UC Santa Cruz scientists. 🧪🌎🦑 They published the first known videos of California coyotes hunting harbor seals.

Happy #saltmarshsaturday!! 🌎🦑 Salt marshes are powerful tools in the fight against climate change because they trap more carbon than nearly any other ecosystem. In this story, I wrote about the scientists who are measuring how much carbon is stuck in the muck of a northern California salt marsh.

Stuck in the muck: Scientists study carbon trapped by Elkhorn Slough

Salt marshes, which have historically been drained and turned into farms or land ripe for real estate development, are emerging as a powerful tool in the fight against global warming.

Walking through a coastal northern California forest that burned a little over 4 years ago. Toyon (Heteromeles arbutifolia), madrone (Arbutus menziesii) and manzanita (Arctostaphylos spp) are THIRVING. 🌎🌿🔥

Anyone here give a hoot about owls? 🦉🌎 If you do, I recommend burrowing into this story about burrowing owls. They are a candidate for endangered species protection in California, and scientists are working to protect one of the last populations in the Bay Area.

How a surprising San Jose spot became a last refuge for the Bay Area’s burrowing owl population

Sandwiched between office buildings and the sewage plant, a 200-acre slice of land is home to some of the last burrowing owls in the Bay Area.
