Monday ice update - #Arctic sea ice extent is currently the lowest on record (JAXA data)

• about 480,000 km² below the 2010s mean
• about 870,000 km² below the 2000s mean
• about 1,290,000 km² below the 1990s mean

Plots: zacklabe.com/arctic-sea-ice-ex…

Line graph time series of 2025'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 purple for the 1980s, blue for the 1990s, green for the 2000s, and white for the 2010s. Thin white lines are also shown for each year from 2000 to 2024. 2025 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 January and April by looking at the decadal average line positions.

London Rules

I recently watched an intriguing series on Apple TV titled Slow Horses. Spanning four seasons, the show features a stellar cast led by Gary Oldman, who delivers a compelling performance as Jackson Lamb, a seasoned yet shrewd MI5 agent in charge of a team of misfit spies. The series masterfully blends humor with thrilling espionage, making it irresistibly engaging—I was hooked from the very beginning. Each season is adapted from one of Mick Herron's novels in the Slough House series, with the first season closely mirroring the events of the first book, and so forth. After finishing the final season, I craved more and decided to delve into the books. I recently completed the fifth installment, London Rules, and highly recommend adding it to your reading list. Needless to say, Mick Herron has firmly secured a spot on my list of must-follow authors.

#books

"The book cover belongs to "London Rules" by Mick Herron. It features an aerial view of London with the iconic Shard building standing out at the center. The title, "LONDON RULES", is boldly written in large red letters at the top, while the author's name, "MICK HERRON", is displayed prominently in white at the bottom. Above the title, there's an intriguing quote by Val McDermid, calling Herron "the John le Carré of our generation". It also highlights that this is "A Slough House Novel" and mentions Herron's accolades as a Crime Writers' Association Gold and Steel Dagger Winner. A striking cover that teases intrigue and recognition!" - Copilot
"This novel is part of the Slough House series, which follows a group of disgraced British intelligence agents. In London Rules, a terror plot threatens the country, and the "slow horses" of Slough House find themselves unexpectedly thrust into action. Led by their irascible boss, Jackson Lamb, the team must navigate political machinations, personal vendettas, and deadly stakes to uncover the truth. The story blends espionage, dark humor, and sharp commentary on the modern intelligence world." - summary by Copilot

🧵 I'd like to share some of the recent and ongoing collaborative projects I’m most proud of from my time at NOAA. Some will continue on in one form or another, but others will not - a direct result of the cuts hitting science across the board.

The “bare minimum” workflow is suggested from downloading data to publishing results. Annotation is then shown for an extension of this work by additional steps including running an Earth System or Integrated Assessment model with optional processing steps. Along with this workflow, different opportunities for improvement are indicated in another style. This graphic is taken from Figure 3 in Kretschmer et al. (2024) in Atmospheric Science Letters.
