Mr. Bob is a true local hero of street safety, and it is so infuriating that he was attacked in this latest instance of senseless car violence. I really hope he makes a full recovery.

Many people were concerned when Robert Clear didn't show up for AM drop-off at Emerson Elementary on Tuesday. As it turned out, he had been just blocks away when police say a driver intentionally struck him after running down two other people in the neighborhood.

After bike collision, Berkeley school rallies around 'Mr. Bob'

"He's always here," said Rachel Terp, Emerson PTA president. "I never saw him miss a day."

Our finalised paper on flat10MIP is finally up in GMD! This is the experimental protocol which allows for a simple, emissions-driven evaluation of TCRE, ZEC and climate reversibility in CMIP7. Thanks so much to all who ran these simulations as a proof of concept! gmd.copernicus.org/articles/18/...

flat10MIP: an emissions-driven experiment to diagnose the climate response to positive, zero and negative CO2 emissions

Abstract. The proportionality between global mean temperature and cumulative emissions of CO2 predicted in Earth system models (ESMs) is the foundation of carbon budgeting frameworks. Deviations from ...

I'm happy to share a paper in Science Advances that makes the case for a weak land carbon sink, drawing upon JPL and Chloris biomass time series. To close the budget with a net land sink of 0.8 Pg C/y from 2000-2019, we propose increases in the ocean sink and decreases in fossil fuel emissions.

So while the ensemble mean shows a nearly symmetric temperature response to positive and negative CO2 emissions, the quick growth of the ensemble spread implies that any scenario that invokes almost any amount of net negative emissions adds substantial uncertainty to the global temperature response.

Charlie Koven @ckoven.bsky.social · Sep 5

Any deviation from the dashed line during the blue phase in the figure above implies a different response to negative than positive emissions. What's most interesting to me is how quickly the ensemble spread grows under negative emissions and then stays throughout the negative emissions phase.

Really excited to see the flat10MIP paper out! Since the preprint, we've added this new figure, showing the ESM ensemble of warming—normalized by the warming at year 100, to remove the uncertainty due to differing TCRE across models—versus cumulative CO2 emissions in the esm-flat10-cdr experiment.

A graph whose horizontal axis reads "Cumulative CO2 Emissions (Pg C)" and vertical axis reads "Normalized Warming (∆T/TCRE)". There is a narrow red ensemble plume, representing temperature during the positive CO2 emissions phase, which follows a straight dashed line, whose slope is 1/1000 (i.e the TCRE line, since warming is normalized to have a value of 1 at 1000 Pg C), and a blue ensemble plume, representing the temperature during the negative CO2 emission phase, which follows roughly the same slope but has a much wider ensemble spread. The acronym TCRE refers to the "transient climate response to cumulative CO2 emissions", which is the value of the proportionality between global warming and cumulative CO2 emissions.

This is such a loss. I've served on the selection committee for this program for the past three years, because it has funded so many incredible people doing such important research over the years. It should be expanding to meet the new challenges of climate change, but instead is totally defunded.

If they close all these research labs, you can't just undo it four years later.

Decades of expertise and tons of specialized equipment will be scattered to the wind. Rebuilding would take ages.

Proposed NOAA budget zeros out ALL climate laboratories and cooperative institutions.

This appears to also end the US greenhouse gas sampling network, including at Mauna Loa, the oldest continuous carbon dioxide monitoring site on Earth.

The Senate version of GOP's budget bill dropped in the middle of the night. Astonishingly, it got EVEN WORSE. It raises energy costs, kills $100s of billions of investment in manufacturing, makes grids less reliable, increases pollution & constrains our ability to compete w/China on AI. Loser stuff.

These ‘let’s attract the hot-shot researchers’ calls ring very hollow to me. Climate science is a team sport. It takes a whole set of skills. We need to be thinking about how to keep critical -teams- integrated. Nabbing hero-model scientist types is not going to retain institutional expertise.

David Ho @davidho.bsky.social · May 3

Countries that are able would be stupid not to try to attract top US researchers. But because other countries have a very limited capacity, it means that only the most high-profile researchers who can relocate will be able to continue their careers.
