One of the most powerful weapons you can wield to fight climate change is … an appliance. A heat pump is a fully electric device that transfers warmth from outdoor air into a building, then reverses in the summer to act like an air conditioning unit. It’s much more efficient …

Earlier this month, the future fell on Los Angeles. A long band of moisture in the sky, known as an atmospheric river, dumped 9 inches of rain on the city over three days—over half of what the city typically gets in a year. It’s the kind of extreme rainfall that’ll …

For nearly a year now, a bizarre heating event has been unfolding across the world’s oceans. In March 2023, global sea surface temperatures started shattering record daily highs, and have stayed that way since. You can see 2023 in the orange line below, the other gray lines being previous years. …

While everyone’s been focused on accelerating the adoption of electric vehicles to cut carbon emissions, a technological hero has been rapidly ascending under the radar: the heat pump. Instead of burning natural gas or coal to produce heat, this fully electric device extracts warmth from outdoor air—even when it’s freezing …

The residents of the 40 floors of San Francisco apartments above our heads may live in luxury, but really, they’re just like the rest of us: showering, washing their hands, doing laundry. Normally in the US, all their water would flush out to a treatment facility, and eventually out to …

Way up in the sky and sprinkled across the seas, two of the littlest yet most influential things in the world have stubbornly guarded their secrets: aerosols and phytoplankton. Today, NASA launched its Plankton, Aerosol, Cloud, Ocean Ecosystem mission, or PACE, to unravel their mysteries. The mission’s findings could be …

Death is coming for the old-school gas furnace—and its killer is the humble heat pump. They’re already outselling gas furnaces in the US, and now a coalition of states has signed an agreement to supercharge the gas-to-electric transition by making it as cheap and easy as possible for their residents …

Stretching thousands upon thousands of miles under your feet, a web of fibrous ears is listening. Whether you walk over buried fiber optics or drive a car across them, above-ground activity creates a characteristic vibration that ever-so-slightly disturbs the way light travels through the cables. With the right equipment, scientists …

The water that pours out of your tap, or that’s unnecessarily packaged in a single-use bottle, or that helped grow the produce in your fridge—all of it may well have come from aquifers somewhere. These are layers of underground material that hold water, and can be made up of porous …

The fillet of flounder sitting on your plate comes with a severe environmental cost. To catch it, a ship running on fossil fuels spewed greenhouse gases as it dragged a trawl net across the seafloor, devastating the ecosystems in its path. Obvious enough. But new research shows that the consequences …
