Fact Brief - Does breathing contribute to CO2 buildup in the atmosphere?
Fast cycling of carbon is seasonal. CO2 increases in colder months when plants decay and release their carbon. In the warmer months, CO2 decreases as plants take it in, along with sunlight, to produce energy and oxygen. Animals — including humans — eat plants, breathe in oxygen, and...
The massive coral bleaching episode signaled by US authorities last month is expanding and deepening in reefs around the globe, scientists warned Thursday. Amid record ocean temperatures, coral bleaching has been recorded in 62 countries and territories since February 2023, the US National...

Mosquitoes are swarming around Houston. The future could bring even more.
After severe rain washed much of Texas, residents are enduring another inundation - of mosquitoes. CONROE, Tex. - Standing in his neatly manicured front yard in this Houston suburb, Mitch Varley stopped for a moment and slapped his right arm. Did he get the mosquito in time before it bit? Not...
Credit...Philip Montgomery for The New York Times I don’t think it’s an exaggeration to say that the Intergovernmental Panel on Climate Change’s 2018 report on global warming drastically changed the way many people thought - or felt - about the climate crisis. That report laid out, with grim...

Clean Energy Is Driving ‘a New Era in American Manufacturing' Across the Midwest
The Midwest is emerging as a major manufacturing hub for the clean energy transition as federal incentives and falling prices for renewables spur companies to invest tens of billions of dollars into new factory operations across the country. In August 2022, Congress passed the Inflation...
Deep-sea sponge's 'zero-energy' flow control could inspire new energy efficient designs
Now, new research reveals yet another engineering feat of this ancient animal's structure: its ability to filter feed using only the faint ambient currents of the ocean depths, no pumping required. This discovery of natural '"zero energy" flow control by an international research team co-led by...
The sharp drop in prices for minerals critical to the green energy transition is masking a looming shortage due to inadequate investment, the International Energy Agency said Friday. In its second annual review of the market for such critical materials, the IEA noted prices for minerals key for...
Floating photovoltaics could limit Africa's future reliance on hydro-generated energy
