Today, we published a study long in the making on how upper and subsurface tropical Pacific waters responded (and maybe will adjust) to warmer global climate. Here’s the story of how we got here after 15 years. many authors but shout out @jfarmersalmanac.bsky.social

Upwelling generates a nutrient-rich “cold tongue” in the eastern equatorial Pacific Ocean (EEP), with impacts on global climate, oceanic biological productivity, and the carbon cycle. The cold tongue ...

"Ocean stratification in a warming climate" | Our ( Lijing Cheng et al) new review article in @nature.com Reviews Earth & Environment: www.nature.com/articles/s43...

Ocean stratification in a warming climate - Nature Reviews Earth & Environment

Ocean stratification — density-related layering of seawater — influences oceanographic and climatic processes. This Review outlines observed and projected changes in stratification, noting a 0.8% dec−1 increase in 0–2,000 m stratification from 1960–2024, and a further 1.4% dec−1 increase by 2100 under SSP2-4.5.

🚨New work🚨 led by Ph.D. student Dipesh Chuphal (IIT Gandhinagar), shows that the recent drying of the Ganga River basin is unprecedented in 1,300 years—more severe than historical famines. This ~multidecadal drying appears forced, but many models do not capture it. ☔️ 🌧️

www.pnas.org/doi/10.1073/...

Time series of standardized streamflow anomaly for the Ganga River from year 700 to 2020 (derived from a hydrological model and from the Monsoon Asia Drought Atlas built from tree rings). The plot shows mostly balanced wet (blue/green bars) and dry (brown bars) years until the 20th century, when the black moving-average line dips sharply after 1990. The 1991–2020 mean (blue horizontal line) is well below the range of previous 1,300 years. Orange dots mark major documented historical droughts, but the recent drying is clearly the most severe.

Observed changes in precipitation and temperature between 1951 and 2020. Spatial distribution of change in (A) annual precipitation (%) and (B) annual mean temperature (°C) between 1951 and 2020 based on the Sen’s slope calculation. Grids with statistically significant trends (P <= 0.05), based on the Mann–Kendall test, are highlighted with stippling. The Inset panels in (A) and (B) represent the interannual variability in precipitation anomaly (%) and temperature (°C) averaged
for the Ganga River Basin (blue boundary). The total change in average precipitation and temperature over the GRB during 1951−2020, estimated using the Sen’s slope, is statistically significant (P-value <= 0.05) based on the Mann–Kendall test.

There's a really nice explanation (with clear graphics) in this @quantamagazine.bsky.social article of why most molecules in the atmosphere (oxygen & nitrogen) don't act as greenhouse gases, but a lot of the far less numerous ones (like carbon dioxide and methane) do. A great teaching aid :)

Why are these extinct cephalopods called "Ammonites"?

The Egyptians worshiped a fertility & weather god called Amon, or Amon-Ra, often depicted as a man with the head of a ram.

The Phoenicians imported this god into their deity 'Baal Hammon'...

Let's talk about how "ammonia" (NH₃) gets its name 🧪.

Along the way, we'll talk about Alexander the Great, ancient Egyptian gods & a Roman misunderstanding.

Let's start with these giant CASTLES made for PIGEONS in Siwa, Egypt, a tiny desert town built around an oasis, with 2 dry salt lakes nearby.

Four tall chimney-like structures made of local adobe/mud that is light sandy colored. From the sides jut bird roosting places, and they're studded with holes to allow the birds to enter the interior, where there are nesting boxes.

The Northern Pacific Ocean is currently smashing temperature records.

And it is reaching these levels far earlier than the current generation of climate models had expected.
