Atmospheric H2 variability over the past 1,100 years - Nature Analysis of the atmospheric H2 variability over the past millennium suggests that the sensitivity of H2 to climate change should be considered in estimates of the radiative consequences of rising...

👏 Heroic effort to extract a H₂ record from ice cores 👏

The samples had to measured in the field immediately after drilling (i.e. fresh out the oven 🥮) to prevent the tiny H₂ molecules from leaking out.

Maybe my music credit worked? Or the term I got to spend in Vienna learning about Gustav Klimt and The Secession Movement?

I learned a lot from the UChicago Core Curriculum. The most important lesson was that I wanted to do Earth Sciences.

-Readings in World Literature
-Self, Culture and Society
-Vienna in Western Civilisation
-Music Materials and Design
-Animal Sensory Ecology (wrote about Trilobite eyes 👁️💠!)

Exactly. And I did double check that the averts grain size in the Megadunes was sand size.

Sand dunes. But where?

One week until #EGU26 abstracts are due!

CL1.2.8 - "Beyond EPICA: old ice and the MPT" looks like it may be the greatest session of the last 1.2 million years (or so).

Will the big❓be filled in with new ice core data?

Archaeological evidence of intensive indigenous farming in Michigan’s Upper Peninsula, USA We describe archaeological evidence of intensive ancestral Native American agriculture in the now heavily forested Upper Peninsula of Michigan. Recent LIDAR (light detection and ranging) and excavatio...

A study in Science reveals an extensive precolonial agricultural landscape in Michigan’s Upper Peninsula, suggesting Indigenous American communities cultivated maize intensively between 1000 and 1600 CE, despite a cold climate and marginal growing conditions. https://scim.ag/49voBGO

I've updated the opportunities part of my website with fresh openings for researchers interested in climate and vegetation science, archaeology, history, and geography at all levels from undergraduate intern to postdoc. Take a look! jedokaplan.github.io/opportunities/

How Did the C.I.A. Lose a Nuclear Device in the Himalayas? (Gift Article) A plutonium-packed generator disappeared on one of the world’s highest mountains in a covert mission that the U.S. will not talk about.

The idea that the Plutonium 238 could have moled its way into a glacier is mind-boggling (and not in a good way).

Excited to share our new PNAS paper!

We find that recent methane growth was driven by agriculture/waste and wetland emissions, while fossil fuel emissions have remained stable despite growth in production, highlighting recent progress and further mitigation potential.

Ancient ‘animal GPS’ identified in magnetic fossils The earliest evidence of an internal ‘GPS’ system in an animal has been identified by researchers, which could help explain how some modern birds and fish

Cambridge researchers have uncovered the earliest evidence of ‘animal GPS’ in tiny magnetic fossils from 97 million years ago.

What left them behind? And what insights can they shed? Dig in: bit.ly/3LQxykH

Field update from Beyond EPICA:

"The camera's light reflected off the myriad of fine ice particulates suspended in the fluid, causing flashes of light and colour that danced and reformed, giving the impression of travelling through a cosmic kaleidoscope"

As far as I’m concerned, we never should have let the Earth form a magnetic field. It made life way too easy.

A magical record! Now 3,000,000 years long! Repost this quote and see if it increases by another order of magnitude.

Years ago we read some of de Vries's papers in a radiocarbon course and the question came up about why he didn't win the Noble Prize alongside Libby. Pretty shocking 😮https://en.wikipedia.org/wiki/Hessel_de_Vries

Phase Angle? Most mornings mine would look like benthic δ¹⁸O and obliquity.

Ice sample being sublimated with infrared light under a vacuum - to the extract the air content from the bubbles.

While the field teams are already in action, preparing to traverse to the drill site, things in the MYIC labs are moving forward. Daniel and Andy made the first serious gas sublimation measurement using our system with some known-composition Law Dome core. 📷 Joel Pedro

Tried the new tool in Google Scholar. Not super interesting, IMHO. www.nature.com/articles/d41...

I did, however, find this correlation with life 🚼, lab 🏗️, and other 🦠 events quite convincing. 😂

Been watching this for years.

Planning logistics and this is my go to reference for how many ice core boxes can fit in a Eurocopter AS350.
