The Arctic Ocean became a major source of greenhouse gases around 56 million years ago, during a period of rapid global warming. . | Credit: Paul Souders/Getty Images The Arctic Ocean was once an important source of greenhouse gases to the atmosphere — …

The Arctic Ocean was once an important source of greenhouse gases to the atmosphere — and it could become one again, researchers warn. Methane (CH4) is second only to carbon dioxide (CO2) in trapping heat in Earth’s atmosphere. Since 2020, human-driven greenhouse gas emissions have increased atmospheric methane by about 10 parts per billion per year, more than twice as …

Matt McGrathEnvironment correspondent Getty Images Pope Leo XIV speaking at the Raising Hope climate conference near Rome Pope Leo XIV has hit out at those who minimise the “increasingly evident” impact of rising temperatures in his first major statement on climate change. Reiterating the words of his predecessor Pope Francis, the new pontiff lambasted critics who “ridicule those who speak …

“I think it’s important to look at the overall work that a senator has done,” said the pope, a Chicago-area native. “Someone who says, ‘I’m against abortion,’ but is in favor of the death penalty is not really pro-life,” he added. “Someone who says, ‘I’m against abortion but I’m in agreement with the inhuman treatment of immigrants in the United …

A new UC Riverside study suggests that today’s global warming could trigger a future ice age. Building on earlier models of rock weathering and ocean carbon cycles, the research highlights how Earth’s climate system might overshoot its regulation, leading to dramatic cooling. This aligns with insights from a recent Science study. How Earth’s Climate Has Historically Cycled Between Heat and …

Earth wouldn’t be the lively place it is without photosynthesis, which harnesses solar energy to fuel most of the planet’s food webs. A variety of plants, algae, and cyanobacteria provide this service, but few do it quite like Prochlorococcus, considered to be Earth’s most abundant photosynthetic organism. Tiny even for cyanobacteria, this marine microbe wields outsized influence in its habitats …

An anonymous reader quotes a report from the Associated Press: For decades, scientists believed Prochlorococcus, the smallest and most abundant phytoplankton on Earth, would thrive in a warmer world. But new research suggests the microscopic bacterium, which forms the foundation of the marine food web and helps regulate the planet’s climate, will decline sharply as seas heat up. A study …
