Line graph time series of 2024's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with white for the 1980s, green for the 1990s, blue for the 2000s, and purple for the 2010s. Thin white lines are also shown for each year from 2002 to 2022. 2024 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between October and January by looking at the decadal average line positions.

The environmental weight of data “Information is physical,” Melvin Vopson tells me. “The fact that information is physical goes back to much older studies. What I did in 2019, I asked myself a question: If a bit of information is physical, and you can detect that energy associated with the bit of information when you erase it, what happens to that energy when the information is at rest, at equilibrium, stored? Where is that energy going? And the only conclusion I could come up with is that that energy condenses into a small mass.”

There is a lot, but the work of Gerry McGovern is a good place to start. His work on 'the environmental weight of data' is compelling: gerrymcgovern.com/the-environm...
