Another global sea level update with satellite altimetry data now processed by CNES/AVISO through late January 2025. It's accelerating.

+ Note that this graph was produced by aviso.altimetry.fr/en/data/proโ€ฆ

Line graph time series showing the latest mean sea level as of 27 January 2025 using data from 1993. There is a long-term increasing trend and a quadratic fit line is shown on the graph with an acceleration of 0.11 mm/yr^2. The current rate of increase is +4.1 mm/yr in the 2013-2024 period.

And now the regional temperature anomalies across the #Arctic over the last 12 months...

Data from ERA5 reanalysis at doi.org/10.24381/cds.f17050d7

Twelve polar stereographic maps showing 2-m air temperature anomalies in the Arctic from March 2025 to February 2025. Blue shading is shown for colder anomalies, and red shading is shown for warmer anomalies. All months are warmer than average overall. Anomalies are computed relative to a 1981-2010 baseline.

ERA5 monthly averaged data on single levels from 1940 to present

ERA5 is the fifth generation ECMWF reanalysis for the global climate and weather for the past 8 decades. Data is available from 1940 onwards. ERA5 replaces the ERA-Interim reanalysis.

Line graph time series of global land mean surface temperature anomalies for each January-February period from 1850 through 2025. There is a long-term increasing trend and large year-to-year variability. The mean surface temperature anomaly averaged for January-February 2025 was 2.16ยฐC for global land areas.

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 engagingโ€”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 Carrรฉ 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

๐Ÿงต I'd like to share some of the recent and ongoing collaborative projects Iโ€™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.

First off, I acknowledge that I am incredibly lucky to have had such supportive mentors that encouraged me to follow my own scientific and cross-disciplinary interests, as broad as they may sometimes be.

This includes introducing a new cost-benefit framework to understand the importance of the timing of enacting climate mitigation on regional extreme weather events.
