Interesting paper by Chelsea Long on the history of Antarctic ice core research out recently in the Polar Journal. A big effort from Chelsea, bringing together 239 publications to do a bibliometric analysis.

I’ve been greatly enjoying the storytelling in Johnathan Meiburg’s A Most Remarkable Creature—centered on the Falkland Islands’ Striated Caracara. Wonderful stuff!

I've been along for the ride with @viticci for more than half those years now, which is hard to believe.

We've accomplished a lot, but I feel like we're just getting started in the best way possible too. It's an exciting time to be building things on the web. 😊

Outside of Greenland and Antarctica, very few land areas were even close to average during the NH summer. You can also see the developing El Nino. Plot from: data.giss.nasa.gov/gistemp/map

In 1979, Jules Charney (and team) produced

"Carbon Dioxide and Climate: A Scientific Assessment”

They examined two models. Manabe's GFDL model and, wouldn't you know, the not-yet-even-described GISS Climate model by Jim Hansen and others. (We call it ‘Model I’ because we're inventive.)

They concluded
"taking into consideration all the above direct effects and feedbacks, we estimate ... 𝚫T for doubled CO2 to lie in the range of 1.6 to 4.5 K”

Again-- things haven't changed so much…

15/many

Next week, #NASA Goddard Institute for Space Studies turns 60, and we are celebrating our anniversary with some retrospective talks on our history… and forward thinking talks about our future.

I have been appointed to present “History and Future of #Climate Modeling”, so I’ve been interviewing many GISS alumni.

The back-stories to the published development are fascinating.

I’ve asked my boss to get a film maker to document these oral histories better. It would make a great documentary imho.

accepted version of new paper available today in Global Biogeochemical Cycles: Magnitude, trends, and variability of the global ocean carbon sink from 1985-2018

This contribution to the RECCAP2 (REgional Carbon Cycle Assessment and Processes) assessment analyzes the processes that determine the global ocean carbon sink, and its trends and variability over the period 1985-2018, using a combination of models and observation-based products. Key points:

The RECCAP2 global ocean analysis provides an authoritative multi-model and observation-based assessment of global ocean CO2 uptake

pCO2-based products yield a mean sea-air CO2 flux from 1985-2018 of -1.6±0.2 PgC yr-1 with a trend of -0.61 PgC yr-1 decade-1 since 2001

Ocean anthropogenic CO2 uptake averages -2.1-2.4 PgC yr-1 from 1985-2018, with a trend of -0.34-0.41 PgC yr-1 decade-1 since 2001

A nice, new out by Jörg Lippold & colleagues on differences in co-occurring planktic . They document how subsurface-dwellers like G. truncatulinoides have ages offset, on average, by ~300 14-C yrs compared to surface-ocean species (like G. ruber & T. sacculifer).

A thread about the extreme anomaly in Antarctic sea-ice extent this year, the present state of knowledge on the reasons for it and why further research is important.
I find the sharp downward trend in Antarctic sea-ice extent that started 7 years ago deeply unsettling, which is why I toot about it a lot.
