Climate News Roundup: Week of 6/26

Prodigal Plankton Returns to the Atlantic, Discovery News, Jun 26

According to researchers with the Sir Alister Hardy Foundation for Ocean Science, a species of plankton called Neodenticula seminae is an Atlantic resident again, 800,000 years after it became extinct in the ocean. The microscopic plant has been documented with sufficient frequency over the last several years to determine that the species has indeed returned. The plankton’s arrival has been facilitated, the researchers say, by melting polar ice providing an easier passage for transport from one ocean basin to the other.

Herder Perceptions of Climate Change, New York Times, Jun 30

Over the last 70 years Mongolia’s climate has warmed almost 4 degrees Fahrenheit. The ability of the herders and their herds to survive depends on their knowledge of the weather and seasonal changes, information that has been passed on through many generations and is essential in the harsh Mongolian climate of cold, windy, dry winters and relatively warm, wet summers. But now the climate is changing, and the herders are beginning to worry about their future. Ninety-nine percent of the herders interviewed say that the seasons have changed.

Poland’s EU budget commissioner in climate change controversy, The Telegraph, July 1

Poland is reliant on coal-fired power stations for up to 90 per cent of its electricity and the former Communist bloc country last week blocked an EU attempt to increase a target to cut CO2 emissions from 20 to 30 per cent. Janusz Lewandowski, Poland’s EU budget commissioner has been forced to recant after he claimed climate change was exaggerated and argued that overambitious EU CO2 emissions targets would hurt his country’s economy.

Exxon Cut Financing to Climate Skeptics, Group Says, New York Times, July 1

Greenpeace U.S.A. has issued a report saying that all of the research funding received since 2003 by Willie Soon, an astrophysicist who has been a critic of climate science, came from oil or coal interests like ExxonMobil and the Southern Company, a utility that burns coal. Dr. Soon, who works at the Harvard-Smithsonian Center for Astrophysics, has researched whether solar variance might be responsible for climate warming.

AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
