Canada recorded its northernmost tornado in almost 50 years

The first thing you notice in Ulukhaktok, NWT, is that everyone waves. Everyone. From passing ATVs. From trucks. From fishing boats and front yards. People wave at you and smile. They ask your name, then remember it for the rest of your trip. They wave because you’re in their community and people here have helped each other for thousands of winters. Open this photo in gallery:A raven flies away with a stolen golf ball clutched in its beak, which isn't uncommon here. I’m waving as well right now, but to a raven, and for separate reasons. I’m on the ninth hole of Ulukhaktok Golf Course competing in the 40th Billy Joss Open and this raven has just stolen my ball. I normally wouldn’t mind (it’s a free drop for raven theft), but the same bird just stole my previous ball, too. Someone recently found a raven nest sporting 200 golf balls. I drop another red Callaway to the ground. Around me, the tundra is green and yellow and dotted with hundreds of purple flowers called saxifrage that the community turns into jams and teas. The afternoon light is a muted lavender and it’s so quiet you only hear golf shots. I try a low runner from 40 yards to the astroturf green, finishing just short.

Giant Clam (Tridacna gigas) from Jiigurru (Lizard Island Group). (Andy Lewis/Coral Sea Foundation)When you swim through the azure waters of the Great Barrier Reef, there is one entity on the seafloor that’s almost impossible to miss: the giant clam. Its huge, fluted shell frames a soft mantle shimmering with electric blue, green and gold. As the world’s largest living bivalve, Tridacna gigas can reach 1.2 metres, weigh more than 200 kilograms and live for over a century. Across their long lives, these clams record their daily life in their shells, creating an autobiographical shell diary. In our new research, we read one of these shell diaries to reconstruct month-by-month climate conditions at Jiigurru (also known as the Lizard Island Group), in the northern Great Barrier Reef. The shell’s story reveals that, before widespread industrial-era warming, Jiigurru’s summers were cooler than today, while winters were surprisingly similar.

What is regenerative farming? How to start it in your own backyardThis fall, goldenrod is abundant and monarch butterflies have been passing through the Moonbeam Blooms Flower Farm in Cane Creek Valley, just south of Asheville, North Carolina.  Owner Jessica Stark won’t be bagging up the leaves, and she says you shouldn't either. Moonbeam Blooms is a regenerative flower farm, where the priority is keeping the soil healthy. “Regenerative farming is focused on really building a relationship with the land and the soil, and has some differences from conventional and even organic farming,” Stark explains. What is regenerative farming? While there’s no legal definition for regenerative farming, its core draws on the USDA’s principles for soil health:Disturb the soil as little as possibleKeep it coveredKeep living roots in the groundGrow a mix of plantsYou don’t need a farm to try it.
