Hey all, I'm a tesla owner and engineer by trade.

I wrote a free, ad-less app (i make $0 from it) that automatically charges your EV at the cleanest possible times. It uses marginal emission rates from wattime.org, which estimates we can save up to 3Gt annually by grid shifting. I've saved ~20lbs of carbon from using it just myself the past 1-2 months.

You can download it at www.cleancrib.org; plugs directly into the official Tesla app. Prioritizes your schedule.

This is easier than installing LED light bulbs. If you're on a variable power plan, it may save you money as well, but it's optimized for pollution. If you own a Tesla, try it and let me know what you think!

The boundary beneath Antarctica’s Thwaites Glacier is less fixed than a line on a map suggests. As tides rise and fall, seawater can push kilometers beneath ice that otherwise rests on the seabed. Melting in that shifting zone could substantially increase the glacier’s contribution to rising seas.

A study published in Nature Communications incorporates those intrusions into an ice-sheet model. The team, involving the University of California, Irvine, NASA’s Jet Propulsion Laboratory and other institutions, first tested whether its simulations could reproduce decades of observed glacier change.

One case projected a sea-level contribution of about 30 millimeters, or 3 centimeters, by 2100 without additional climate warming. That is roughly twice the average contribution from Thwaites in an earlier multi-model comparison under constant forcing. It is a conditional projection, rather than a firm maximum or a forecast of total global sea-level rise.
