Everyday items like coffee machines, video games consoles, and laptop chargers can drain energy even when they’re turned off, accounting for 5 to 10% of nationwide home energy use. Columbia Climate School Dean and energy expert Alexis Abramson explains what you can do about it. Via PBS NewsHour.

Are ‘vampire devices’ draining energy in your home? Here’s what to do

Leaving electronic devices plugged in can account for "...about 5-10% of home energy use, depending on factors like the age of the equipment...what kind of systems you have and how much they've improved over time," says energy expert Alexis Abramson, dean of Climate School.

Team led by @seismoshuck.bsky.social with LDEO's Suzanne Carbotte, Anne Bécel, colleagues has directly observed subduction zone actively breaking apart, shedding new light on how Earth’s surface evolves & raising new questions about earthquake risks in Pacific NW: lamont.columbia.edu/news/earths-...

Researchers and crew aboard the R/V Marcus G. Langseth during the 2021 Cascadia Seismic Imaging Experiment (CASIE21) experiment, which collected seismic data to image the Cascadia Subduction Zone analyzed in the new study. About 20 scientists from Lamont-Doherty Earth Observatory, Louisiana State University, University of Washington, and a number of other institutions are analyzing the dataset as part of the Cascadia Region Earthquake Science Center (CRESCENT), a community studying earthquake hazards in the Pacific Northwest. Lamont’s Suzanne Carbotte, seated first row second in from the right, is the chief scientist for CASIE21, which is supported by the National Science Foundation.

While El Niño often brings drought conditions to India, it also increases likelihood of devastating downpours in some of most heavily populated regions, finds new study by City College of NY, @lamont.columbia.edu, @columbiauniversity.bsky.social, UCLA scientists: lamont.columbia.edu/news/study-e...

How extreme rainfall days within India change with the El Niño-La Niña cycle. Blue shades mean extreme rain is more likely and brown shades mean less likely during El Niño summers compared to La Niña summers.

🚢 During transit on MGL 2509, the R/V Marcus G. Langseth used high-resolution multibeam sonar to map a stretch of seafloor previously uncharted in this level of detail! With only 27.3% of the seafloor mapped per @seabed2030.bsky.social, there is so much more of our planet to explore.
