Collapse of the Atlantic meridional overturning circulation would lead to substantial oceanic carbon release and additional global warming - Communications Earth & Environment The collapse of Atlantic Meridional Overturning Circulation would result in increase of 47-83 ppm of global mean atmospheric carbon dioxide and 0. 2 °C of additional global warming at higher carb...

🌊 If the AMOC collapses, the ocean could flip from a carbon sink → carbon source.

Mechanism:
↓ NADW formation
↓ Carbon sequestration efficiency
↑ Atmospheric CO2

Net effect: a shift toward ocean-driven carbon release and enhanced warming (positive feedback)

Cherry Hill schools weighing $14.5 million in cuts and layoffs to close budget gap for 2026-27

Cherry Hill is one of 13 South Jersey school districts that is set to receive a reduction in state funding for the 2026-27 school year under Gov. Mikie Sherill's proposed budget.

My point is that if we lose talented young scientists now, it’s going to be a multigenerational gap. It’ll take the US a very long time to recover from this wanton destruction (if ever).

30+ years ago, I learned an analytical technique as a summer intern that set the course of my career. Now, I'm the only scientist in the world still using it. The scientists we don't train today because of funding and program cuts from the Trump regime are the scientists we won't have in the future.

Nature Report, Killed by Trump, Is Released Independently

The report highlights the grim state of freshwater ecosystems, degraded marine and terrestrial ecosystems, and the risk of extinction for many species. But it also emphasizes the potential for improvement through conservation, restoration, and renewed connections between people and nature.

Viruses in marine sediments: a review of their effect on biogeochemistry and microbial interactions | Applied and Environmental Microbiology In the ocean, viruses are known to mediate the carbon cycle, keeping dissolved organic carbon (DOC) in the microbial loop and preventing its movement into secondary consumers (1). However, few direct ...

⚒️🧪Fiery Mud Volcano Eruption!

The Daşmərdan (Dashmardan) mud volcano in Azerbaijan erupted ~16:50 on the 30th Jan 2026. The eruption lasted ~15 mins and was accompanied by a pillar of flame several hundred meters high. Daşmərdan had previous documented eruptions in 1866, 1954, 1976, 1986 and 2011.

Many programs (like ours) allow students to transition from MS to PhD after a year if everything is going well. This provides the student an opportunity to really "feel" the various aspects of grad school, to come to an informed decision. Ask prospective advisors if their program does that. 2/2

My advice to undergraduates:

Do *not* sign on to a PhD just because it's a 'next step' and you don't know what else to do. A master's program is a much better option in that scenario. You can find out if you genuinely enjoy the endeavor and, if not, it's only 2 years and you get a great degree! 1/2
