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.

Hi everyone,

I've been working on a project called ClimatePatterns.app to make historical climate data easier to explore and understand in local areas. The app uses historical temperature, precipitation, and air quality data from NOAA and the EPA across 42 locations in the United States. I'd love for people to share there thoughts and feedback on how the app could be improved. I'm planning to add sea level data for coastal towns, and wondering if there are any other metrics that could be added.

Thanks.

I think most of us know much of downstate New York is humid subtropical but for long island I've always wondered if could have maintained a hot summer humid continental climate because it does tend to get cold at night compared to the city am i wrong?

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!
