Credit: CC0 Public Domain Hurricane Idalia and the Hawaii firestorm were the most notable weather disasters in the U.S. in 2023, but they were far from the only ones. In 2023, 25 weather or climate disasters caused at least $1 billion in losses and the deaths of 482 people, according to the National Centers for…

A study by the University of Washington, analyzing an 800-year-old ice core, suggests that phytoplankton populations in the North Atlantic have remained stable since the industrial era. This finding challenges previous assumptions of a significant decline and highlights the impact of industrial pollutants on atmospheric chemistry.

Since the 1980s, seismic stations have been detecting an increase in ocean wave intensity, correlating with climate change. A Colorado State University study, analyzing over 35 years of data, found that ocean waves have become significantly stronger, reflecting an increase in storm severity due to global warming. This seismic data, revealing long-term trends and changes…
