With warming winter temperatures, the safety of lake ice is a growing concern. “It’s only a matter of three to five days where you can go from safe ice conditions to totally unsafe,” Prof Sapna Sharma tells @AP | @Sharmalab @YorkUScience https://t.co/5JVQYzAzz0

Why doesn’t flowing water freeze at the same temperature as still water? Listen to #YorkU Postdoctoral fellow Josh Culpepper answer that CBC Quirks & Quarks listener question. Hint: moving water mixes things up https://t.co/BuAE48Qtmc @YorkUScience @jaculpepper @Sharmalab

“What we’re seeing and what we’re predicting is that climate change is contributing to more white-ice conditions,” #YorkU Prof Sapna Sharma tells @SN_Explores. Which can lead to unsafe lake ice conditions, adds Postdoc Joshua Culpepper. @Sharmalab https://t.co/g5gXFxBWkm

Counterintuitive finding: in small lakes most vulnerable to low under-ice dissolved oxygen concentrations, shorter winter ice cover was associated with expansion of bottom-water hypoxia.

Our study "Global dominance of seasonality in shaping lake-surface-extent dynamics" is now published in @Nature. We reveal how seasonal rhythms govern the dynamics of ~1.4 million lakes globally.

I was at this game! My first of many @Raptors games and since then, I have been hooked! Let’s go Raptors!

On this day in 1996, the Raptors took down MJ and the Bulls at the Skydome. One for the books.

💧Join us for a crucial World Water Day discussion!

Water insecurity disproportionately affects women & marginalised communities, yet their voices remain underrepresented in water governance & leadership. It’s time for change.

My data comes from NOAA and the people who work there. The NOAA Great Lakes Environmental Research Lab (GLERL) is the reason we have ice records dating back to the 1970s. #NOAA #GreatLakes
