Let’s replace all the horse evolution displays (which misrepresent evolution as linear and goal-oriented) with chaotic tableaus of all the shapes crocodiles have been #FossilFriday

Gotta love Rhodies

The meandering planform of the Purus River (a tributary if the Amazon), shown as white wiggles on a black background. The width of the river and the size of the meanders are increasing downstream (top to bottom, left to right).

What if you laid out all the meanders of a river along a straight line, so that you can break the river into straight-ish segments and fill arbitrary spaces? This is the Purus River in Brazil; you can see how it is getting wider and the meanders are getting larger in the downstream direction

Kind of begs the question whether geothermal companies require a fundamentally different approach to capital compared to oil and gas companies. Different time horizons and revenue models

Not entirely. There's natural topography and glacial landforms in it

4th graders are surprisingly smart. Some will have no problem with this

Agricultural land with many long narrow fields shaded various colors from green to yellow, indicating the normalized difference vegetation index of vegetation greenness. Fields are oriented north-south parallel to drumlins and ice sheet flow direction.

Drumlinized land use, shaded by NDVI. Fields with various degrees of vegetation greenness, oriented parallel to drumlin long axes reflecting two different ice flow directions across the Green Bay Lobe, southern Wisconsin.

Sediment on the move

It's all about the spring flowers

Two zeros, one pic

We have reached peak daffodil

What’d you say?

Spring has sprung

Also I couldn't find USGS. Space for it next to NPS and BLM

Modelling subglacial fluvial sediment transport with a graph-based model, Graphical Subglacial Sediment Transport (GraphSSeT) Abstract. A quantitative understanding of how sediment discharge from subglacial fluvial systems varies in response to glaciohydrological conditions is essential for understanding marine systems aroun...

🚨 Paper alert! New research co-authored by #VAW member Mauro Werder introduces GraphSSeT, a model that advances #subglacial #sediment #transport analysis by simulating sediment discharge dynamics, grain size transport, and hydrology interactions.

The colors are atrocious. Yellow on yellow??

Wait what season is it?

Top financial watchdog warns climate change set to trigger market panics Basel-based FSB says damage caused by floods, droughts and fires threatens broader pullback in lending

💴 The world’s top financial stability watchdog warns that mounting incidents of climate disasters could spark panic in financial markets, with pullbacks in lending and dampened investor confidence. By Martin Arnold and @leeharris.bsky.social for financialtimes.com

Wow what a sunset tonight

Loving these calm and clear winter evenings we’ve been having

It seems very similar emails went out to all federal agencies?

The Bluesky algorithm is eye opening.
X is manipulating the Following feed so heavily that I see almost nothing from the accounts I follow over there.

Ground source heat pumps for heating and cooling

How so?

Realistically, no one knows what the future holds and user growth is not going to be linear.
At the moment, BlueSky growth appears to be accelerating upward while Twitter shrinkage is accelerating downward.
