I literally laughed aloud at @beebrookshire.bsky.socialā€™s newsletter today, prompting my small children to demand leech-centric storytime.

The Atlantic hurricane season begins tomorrow. While climate change doesn't create these storms, it's making them much more dangerous. In a warmer world they're stronger, intensifying faster (especially near land), dumping a lot more rain, moving more slowly & weakening more gradually over land.

Once upon a time, someone was very upset at my lawyer fatherā€™s role in convicting him, and expressed this by mailing photos of me at my preschool. My heartfelt gratitude to all who enforced consequences today, and I dearly hope they & their families survive The Unhinged unravelling in rage.

Nope, no naturally-occurring crystalline structure for sugar. You can find baking soda as nahcolite, but the stuff you buy in shops is synthetic.

Ice (or salt) needs to be wild to be a mineral, since minerals must be naturally-occurring. Rocks are any solid collection of minerals or mineral matter, but donā€™t need to be naturally-occurring. Technically, you could make a synthetic rock as long as youā€™re careful about sourcing components!

As your friendly neighbourhood geoscientist, it is my duty to remind you that salt and ice are rocks. Please do not consume granite on a daily basis.

Congratulations!! It still blows my mind that we didnā€™t know where any exoplanets were when I was little, I could point out the countably-few confirmed exoplanets when I worked in a planetarium, & now I just point to a random place to tell my kids ā€œthereā€™s a planet!ā€

My youngest presented me with a rock for the first time. Itā€™s a lovely white granite. Slow-cooled, plenty of silica, echoes of grand eruptions. My oldest immediately picked out the opposite, a black basalt. Quick-cooled, low silica, whispers of oceanic rifts.

I mean, polar bears ARE local bears in Canada. Itā€™s a northern country. But yes, polars and grizzlies create hybrids (pizzlies & groalers), which is certainly a mess to contemplate for many, many reasons.

Once upon a time & long, long ago, I had a bear torment me during an induced polarization (IP) survey, nuzzling into my injection point, chewing my cables, & leaving enormous poops on my lines. Over 60 days on the gig & the biggest aggravation was pinning out my chewed connectors each morning.

Right?? Like I would REALLY pause on my risk assessment if polar bears were part of this scenario, but if we have polar bears in the woods a whole lot of other shit has gone deeply wrong.

But men? Especially ones deliberately seeking you out when they have an entire woods to enjoy? My tips & tricks heavily focus on avoiding the scenario entirely, soā€¦ guess Iā€™m teaching my kids to go find the bear? Maybe lay out some cables, see if unknown men find them as irresistible as bears do.

Iā€™m teaching my kids to be respectful of bears. Travel loudly, spot the cubs before passing mama, keep your camp tidy & rubbish secured, fed bears are dead bears, the full collection of Canadianna wisdom.

At worst, theyā€™ll splat into a startled bear while biking: www.nsnews.com/local-news/g...

I have a handful of bear stories, all involving at most a bit of aggravation of extra work or twiddled time. Theyā€™re easy to retell as amusing low-stakes misadventures. But my stories of men in the woods are grim, gross, or unpleasant lessons learned. Theyā€™re stories I tell unhappily as warnings.

Iā€™m deeply amused by the entire concept of choosing if youā€™d rather share woods with a strange man or a bear. Having done both repeatedly for years, all my horror stories involve men. Bears were far more polite. At worst, they ate cables. Polar bears would make me pause, but they donā€™t like woods.

Hi. Excuse me? I have a question, too For allergy purposes, cashew/pistachio are identical. Both are tree nuts, but so are coconuts (in the US; Canada allergy labeling ignores coconut). And cashew allergies are related to mango (pit) allergies. Are cashew & pistachio drupes? Or mangoes tree nuts?
