Correction: "Born in East LA" was a 1987 movie (apologies for the transposition error)

Share your comments on NCAR with NSF Tell NSF the future that you want for NCAR by 13 March

We have a critical opportunity right now: NSF is requesting input on the future of NCAR, which is under threat of being dismantled. I just submitted my comments to NSF, and you can too, using AGU's easy instructions and form. agu.quorum.us/campaign/154...

Note to self: Take advantage of opportunities to reach out to old acquaintances. I remember them fondly for a reason. It feels good to know they continue to exist out in the world.

Winogradsky column - Wikipedia

For those, like me, who didn't know what these were before today en.wikipedia.org/wiki/Winogra...

A colleague showed me Winogradsky columns from their biology course. The dynamics are biological (obviously), chemical (reaction rates), physical (diffusion), and mathematical (partial differential equations)

d/dt(Oxy.) = Diff.*d^2/dz^2(Oxy.) -RxRate*Oxy.

Disciplinary distinctions are a lie!

Law enforcement use of lethal force is always a failure. At best, insufficient resources are deployed to make a scene safe. At worst, a violent individual has been allowed to cloak their wrath under the color of law. Either way introspection and reform are needed.

For Pez, like gifts during the holiday, the biggest joy is in the giving (well dispensing).

This is utter folly. NCAR hosts and maintains multiple basic tools the broad scientific community uses to process large data sets. This is the equivalent of salting the earth and putting towns to the torch. I struggle to understand the wanton needless destruction. www.usatoday.com/story/news/p...

NCAR is quite literally our global mothership.

Everyone who works in climate and weather has passed through its doors and benefited from its incredible resources.

Dismantling NCAR is like taking a sledgehammer to the keystone holding up our scientific understanding of the planet.

Unbelievable.

The apparent jump in arctic growth rate at the start of December is likely an artifact of how the rate is calculated using a low order polynomial fit. Do not read too much into it.

Annually arctic sea ice grows fastest between late Sept. and early Nov. peaking above 10^5 sq km/day. The peak has been getting later and and higher. This year it was later but it didn't make it above 10^5 sq km/day.

Never forget the Buckingham π theorem

The damped driven harmonic oscillator is the basic building block model of a stable system with one dynamic quantity. Do you have an example that is as simple? Are you sure it can't be reduced to a driven oscillator?

Are we sure it is thermostasis and not oppositional defiant disorder?

Or it's an artifact of smoothing the data. This is the same graph using a 14 day window to smooth the data and estimate the rate of change.

In October arctic sea ice expands over 100,000 sq km per day. It hasn't reached that rate (yet?). There are historically two periods of rapid expansion one in October and a secondary one in December.
Probably too early to say if the deviation is significant.

They finally came for a grant that I had a small part in. I knew it was a question of when. Thanks to those who shared their losses. Your openness helped me prepare for this and have realistic expectations.

Waves carry momentum and energy. Energy can dissipate in the roiling surf. The momentum (parallel to the beach) can live on as an along shore current where the waves break.
