A comprehensive new report (https://academic.oup.com/bioscience/article-lookup/doi/10.1093/biosci/biaf149) published in the journal BioScience reveals that Earth's climate crisis is accelerating at an alarming rate, with 22 of 34 planetary vital signs now at record levels. The study, co-led by Dr. William J. Ripple of Oregon State University and Dr. Christopher Wolf of Terrestrial Ecosystems Research Associates, presents stark evidence that Earth is approaching climate chaos.

A new study published in SCIENCE CHINA Earth Sciences reveals that the Atlantic Multidecadal Oscillation (AMO) plays a dominant role in driving interdecadal changes of compound hot drought events in Northern East Asia. By analyzing observational datasets and conducting climate model experiments, researchers demonstrate that AMO-induced Rossby wave trains modulate the subtropical westerly jet, leading to decades-long fluctuations in heat and drought risks across the region. The findings offer critical insights for improving decadal climate prediction and disaster preparedness.

Sporadic-E is a phenomenon that occurs in the ionosphere that can disrupt radio communications. Through simulations, researchers have found that rising CO₂ levels in our atmosphere could lead to sporadic-E becoming stronger, occur at lower altitudes, and persist longer at night.
