Rain Makes Skulls Bigger—in Mice

by Kimberly M. S. Cartier 4 October 202228 October 2022

New research shows how regional weather, shaped by towering mountain ranges, might influence the size and shape of local rodents.

A bright red, orange, and yellow thermal image of London and the surrounding area maps hotter and cooler areas of the city. The center of the image is the city of London, which is yellow, indicating that it is hotter than surrounding suburbs, which appear in varying shades of orange and red. The suburbs tend to become cooler, and appear darker red, moving toward the edges of the image. The River Thames snakes from right to left across the center of the image. It and several water reservoirs to the left of center are black, indicating that they are much cooler than the neighboring land.

Satellites Can Accurately Take Earth’s Temperature

by Rebecca Dzombak 28 September 202228 September 2022

Satellite-based measurements of land surface temperature may prove to be an essential pairing with near-surface air temperatures to understand global warming and cooling trends.

Exploring Carbon Emissions in Peatland Restoration

by Sarah Derouin 22 September 202228 February 2023

Rewetting bogs can increase methane emissions in the short term, but ultimately the approach helps restore peatlands and create larger carbon sinks.

The Long-Lasting Impact of a Nuclear War on the Ocean

by Nicolas Gruber 12 September 202227 September 2022

Model simulations of the impact of a large-scale nuclear war reveal long lasting effects with much of the ocean not returning to pre-war levels despite the cessation of the initial cooling.

A Significant Advancement in Modeling the Global Methane Cycle

by Jiwen Fan 8 September 202213 March 2023

The capability to fully model the global methane cycle advances the international climate science community’s ability of providing essential evidence to underpin climate mitigation policy.

A tall jet of lightning extends upward from a bright thundercloud in front of a dark starry sky. The gigantic jet is bright white at the base and then transitions to blue and then to red as it reaches upward. The top of the jet is wider than the base.

Gigantic Jet of Lightning Mapped over Oklahoma

by Kimberly M. S. Cartier 7 September 20227 September 2022

The most powerful gigantic jet ever recorded fortuitously appeared over a sensor array in Oklahoma, enabling scientists to map the structure of the phenomenon for the first time.

Side-by-side images show fish-eye-style photographs of a starry evening sky illuminated by different subauroral events. The left image shows a SAR arc, a reddish arc that spans the sky. Beneath the arc the sky transitions from bright green at the horizon to purple and is partially obscured by clouds. The right image shows a STEVE phenomenon. Part of the red SAR arc is still visible but is much fainter and more of a pink color than its original red. The green and purple sky is more muted in color, and more stars and the band of the Milky Way are now visible. In both images, the silhouette of some shrubs is visible.
