The Washington Post@washingtonpost.com · 6mo agoBreaking news: Trump officials have struggled to figure out how to increase military spending by $500 billion. The White House budget chief was among those who objected to the defense secretary’s plan to increase military spending by roughly 50 percent.
An explosive #eruption of Hayli Gubbi #volcano, located SE of Erta'Ale in the Afar Rift (Ethiopia), began at ~08:30 UTC on Nov 23. Eruption onset was fortuitously captured by a @planet.com overpass at 08:31 UTC. Hayli Gubbi has no record of Holocene eruptions. Toulouse VAAC reporting ash to ~15 km.
New paper alert🚨 In this new article in @natgeosci.nature.com we use a multidisciplinary approach (geochemistry, geophysics and mathematically modelling) to see pulsing in the mantle plume beneath Afar and how the flow varies along the rift See the 🧵 below: www.nature.com/articles/s41...

The mantle upwelling beneath the Afar rift may be influenced by tectonic processes in the overriding lithospheric plates that shape the distribution of both the compositional heterogeneities and abund...

Every year, billions of vehicles worldwide shed an estimated 6 million tonnes of tire fragments. These tiny flakes of plastic, generated by normal driving, account for 28% of microplastics entering the environment globally. Heavy vehicles eg SUVs/EVs especially. Via @us.theconversation.com
Car tyres shed a quarter of all microplastics in the environment – urgent action is needed
Tiny flakes of plastic, generated by the wear and tear of normal driving, eventually accumulate in the soil, in rivers and lakes, and even in our food.

The scientific community is at a pivotal moment right now. And we are seeing things start to shift. Now is the time for scientists and scientific institutions to step up. No one is coming to save us. 🧵

Mauna Loa Observatory’s Lease May End Because of NOAA Cuts
NOAA, the nation’s leading climate science agency, may lose dozens of offices, including one that is key to the Mauna Loa Observatory in Hawaii.

New: A NOAA lab in Hawaii that is connected to the longest-running observation of global greenhouse gas concentrations is slated for closure in August, according to a list of lease terminations Democratic members of Congress shared with @washingtonpost.com.
Trump moves to close government lab that tracks planet-warming pollution
The lab is connected to the Mauna Loa Observatory, where scientists gather data to produce the Keeling Curve, a chart on the daily status of atmospheric carbon dioxide concentrations.

This week I was at @climatecerege.bsky.social to meet colleagues and sample some cores and I stayed to join the women’s demo on March 8th - what a blast!
This is a brilliant resource!! Please share widely!
Dr. Rebecca Barnes (she/her)@waterbarnes.bsky.social · 2y agoThis is amazing 😍😍 @500womensci.bsky.social has made cards for each state on funding for NSF and NIH avail for download bit.ly/NSF_bystate & bit.ly/NIH_bystate if they are helpful for folks

One might think that Nazi crimes and palaeontology never overlapped, and yet... Have you ever wondered what happened to tens of palaeontologists & geologists in the Nazi-occupied Poland? How academics helped to bring down the fascist regime. And a curious story of Schindler-equivalent in geology. 🧵

Mighty floods of the Nile River during warmer and wetter climates
Sediment cores off the Nile mouth reveal insights into effects and causes of heavy rainfall episodes about 9,000 years ago. That will help to prepare for weather extremes in a changing climate.

8. What’s #next? 1) estimating #FloodMagnitude (volume water) -> hydrological models. 2) Identifying relevant climate modes -> climate models. 3) Elucidating #rainfall dynamics on annual-centennial timescales -> paleo-records & #models (PMIP4 protocols!) #paleoclimates
7. Why is that #important to know? 1) warmer climates will lead to an increase in regional variability design #infrastructure (flood protection). 2) knowing #pacemakers #predicting extreme #floods early-warning systems in #vulnerable regions.
6. These were also found in records of past #Nile levels from ancient Egyptians during the #CommonEra (so-called #Nilometer records) -> stationarity of climatic forcing/#teleconnections under different climates
5. We also detected climatic #pacemakers: El Nino Southern Oscillation #ENSO (<10 yr timescales) and multi-decadal oscillations (50-100 yr)
3. We used a #varved sediment core from offshore the Nile mouth to reconstruct past #Nile floods during the #GreenSahara -> we observe much stronger #floods AND a higher variability of floods @varveswg
2. Wetter intervals of the geological past (e.g., North African Humid Periods or #GreenSahara phases) are useful (partial) #analogues
