Learning from Native American wildfire management strategies

For several months in 2019, it seemed wildfires wouldn’t rage across the West as they had in recent years. But then came the dry autumn and California’s Santa Ana and Diablo winds, which can drive the spread of wildfires. Utilities are shutting off power across the state to reduce the risk of damaged equipment or downed trees on wires causing fires. There’s no lack of…


As climate change erodes US coastlines, an invasive plant could become an ally

Many invasive species are found along U.S. coasts, including fishes, crabs, mollusks and marsh grasses. Since the general opinion is that invasives are harmful, land managers and communities spend a lot of time and resources attempting to remove them. Often this happens before much is known about their actual effects, either good or bad. The common reed Phragmites australis is a tall perennial grass with…


SDSU: The shape of Imperial Valley water

SDSU researchers examine the effects of shrinking water supplies in the Imperial-Mexicali Valley. Whenever it rained, six-year-old Trent Biggs would get in trouble for digging ditches in the school playground. “I just liked watching water flow around,” he explained. He still does. Now a San Diego State University geography professor, Biggs leads water-use studies from the Himalayan foothills of Nepal to the Amazon rainforests of…


Microplastics everywhere; in our bodies, too

What do beer, oysters, table salt, air & tap water have in common? They’re all ways humans are ingesting microplastics, tiny bits of plastic waste ubiquitous in oceans, lakes and rivers and even soil and air. Wildlife as diverse as whales, seabirds, fish and zooplankton are polluted by ingesting plastic debris. It’s naïve to assume that humans, sharing the same global environment and eating at…


Don’t kick climate change down the road

Mankind has only 12 years left to make unprecedented cuts in greenhouse gas (GHG) emissions if we want to stave off unimaginably catastrophic effects of runaway global warming. This is the warning detailed in October’s report from the United Nation’s Intergovernmental Panel on Climate Change (IPCC), the recognized global climate authority which represents the investigations of hundreds of climate scientists and 195 participating nations. A…


Plastic ocean pollution and climate change

Although burning fossil fuels is the primary cause of global warming, fossil fuels could also be driving climate change via a completely different mechanism involving ocean plastic debris and tiny, bioluminescent fish living hundreds of meters beneath the ocean’s surface. Lanternfish (aka myctophids) are only a few inches long typically but so ubiquitous that they account for over half the ocean’s total fish-mass. They are…

Collective action will solve climate crisis

I fancy myself an environmentalist.  I recycle, backyard compost, have rooftop solar, rarely use AC or heat, drive a hybrid, don’t have a lawn and eat vegetarian. Yet the truth is I am as responsible for climate change as the next guy. Here’s why. Doing those things makes me feel good about myself, but they don’t move the world measurably closer to solving the climate…
