Farmers are contending with huge spikes in fertilizer prices. The Biden administration is paying US companies to boost synthetic fertilizer production, but there are other, more sustainable options.
Exposure to hot and dry conditions can damage the DNA of nestling birds in their first few days of life – meaning they age earlier and produce less offspring.
Other presidents used the Defense Production Act to boost fossil fuel supplies. Biden is now using it to boost clean energy. But just ramping up production isn’t enough to succeed.
Already critically endangered, the southern bent-wing bat is still declining in a drying climate. If we don’t step in, it will likely be extinct within three generations of bat.
Renewed interest in nuclear energy will go nowhere unless we talk about carbon pricing. As energy minister Chris Bowen points out, nuclear is extremely expensive.

As nations pledge to preserve swaths of ocean within their territorial waters, a marine scientist explains why some marine protected areas shelter ocean life more effectively than others.
Australia’s Traditional Owners have survived climate shifts before. Bringing traditional ecological knowledge in contact with western climate scientists could help First Nations survive this one.
Only 13% of US solar industry jobs are currently in manufacturing. The Biden administration hopes the sector will grow fast, but that might not be so simple.
Thwaites Glacier’s ice shelf appears to be splintering, and scientists fear it could give way in the next few years. A polar scientist takes us on a tour under the ice to explain the forces at work.
The collapse of the Atlantic meridional overturning circulation would profoundly alter the anatomy of the world’s oceans and climate. New research explores the consequences.
