Ice Age Testing Reveals Challenges in Climate Model Sensitivity

by Morgan Rehnberg 2 March 202122 February 2023

Increased reflection of incoming sunlight by clouds led one current-generation climate model to predict unrealistically cold temperatures during the last ice age.

Rainfall Change with Warming More Consistent than Anticipated

by Alessandra Giannini 26 February 202114 October 2021

Dew point temperature better explains precipitation change with warming than temperature itself, and the relation is more spatially coherent than previously thought.

Why are Earthquakes on the San Andreas Seasonally Modulated?

by Victor Tsai 19 February 20219 February 2022

There is growing evidence that some earthquakes occur seasonally but also that water loading cannot explain these observations.

Spacecraft Reveal New Details of Magnetic Reconnection

by Morgan Rehnberg 15 February 202118 July 2023

Energetic electrons are accelerated directly by magnetic reconnections and can act as tracers of large-scale magnetic field conditions.

Earthquakes Can Acidify Groundwater

Aaron Sidder, freelance science writer by Aaron Sidder 10 February 202113 January 2022

Fracturing during microearthquakes can cause groundwater pH drops. The change is temporary but can be equivalent to the difference between water and vinegar.
