Wildfires and fossil fuel burning in 2024 contributed to the biggest annual rise in atmospheric CO2 levels ever recorded at the Mauna Loa Observatory in Hawaii

Increased carbon dioxide in the atmosphere this year will exceed key trajectories for limiting warming to 1.5°C, Britain's Met Office predicted Friday, with researchers reaffirming that that only "drastic" emissions cuts can keep the target in sight.

Between mountains in Hawai'i, innovative scientists show precision timing at the quantum limit.

'Not good,' said one climate scientist, referring to a near-record increase in CO2 levels recorded since May of last year.

Climate change didn't make the dry spell more likely, researchers found, though extreme heat probably made it hurt more.

New research shows global carbon emissions from fossil fuels have increased over the past year despite most of the world committing to net zero targets.

Republican presidential candidate Vivek Ramaswamy, a self-professed "unapologetic proponent of greater use of fossil fuels," has repeatedly cited false or misleading statistics to downplay the risks of climate change.

Discussions of "climate change" or "global warming" tend to focus on increasing temperatures in summer, especially the current run of severe heat waves.  The 85-page summary of the Intergovernmental Panel on Climate Change (IPCC) report mentions "winter" only once, the surname of one of the authors, but the adverse health effects of cold winters have long been recognized. Can the health benefits of warmer winters…

The Bureau of Meteorology this week declared a 70% chance of an El Niño developing this year. This raises concern for the health of the Great Barrier Reef, which is under continuing threat from climate change.

It's one of the most powerful forces warming the Earth, leading to increasingly severe droughts, wildfires and floods. It's also invisible. So how do we see start seeing carbon?
