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 bit.ly/3PfSm7a

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 bit.ly/4lgGtJU @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 bit.ly/3OpDgv4

@Lake_sIchiro Thanks!

@Sharmalab I have not got official information yet. It seems 2days or 4 days.

Hi Sapna @Sharmalab Lake Suwa was fully frozen on January 26, but temperatures increased soon afterward. Yesterday, Shinto priests declared Akenoumi (meaning the lake failed to remain frozen), indicating that Omiwatari did not occur this winter. yomiuri.co.jp/national/20260…

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. doi.org/10.1073/pnas.2…

@dzevela @UofTNews @theACADIC @Ai4Pep So amazed by you, Jude and your inspiring work! Great article!

Grateful to @UofTNews for sharing my journey—from a small village in Cameroon with no hospital or school, to leading global AI & health equity work through @theACADIC & @Ai4Pep . Thank you, Sharmeen Somani, for the spotlight. Check this story out : utoronto.ca//news/selling-…

Today on #World Environment Day, we’re launching 3 FREE courses on water sustainability: i) Climate change impacts on ice; ii) Indigenous relationships to water, and iii) Big data analytics. Enrol here: yorku.ca/research/water…

@UNITAR Global Water Academy and #YorkU launch three new, FREE courses about water today – #WorldEnvironmentDay2025 to raise awareness and foster action on UN Sustainable Development Goal 6: Clean Water and Sanitation @Sharmalab yorku.ca/news/2025/06/0…

@dzevela @UofT_dlsph @AimmLab Congratulations Jude!!

Just received the Excellence in Research Award from my School! Grateful to God, my mentors, colleagues at @UofT_dlsph , funders, students & postdocs at @AimmLab, and my family. This energizes me to keep working with communities to build AI & math tools that turn data into action

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. 🔗 nature.com/articles/s4158… #ClimateChange #RemoteSensing #Hydrology #LakeDynamic

@SheilaCoteMeek Sorry for your loss, Sheila.

My father passed on to the spirit world this morning. I will miss him dearly and was so blessed he spent the last 3 years living me and my partner. His life was filled with hard work but also full of many adventures! There was nothing he wouldn’t try, so inquisitive 😢RIP Dad ❤️

The burden of the climate crisis will be felt more by younger generations than older generations, according to a paper in @Nature. go.nature.com/4kbba1n

Please RT! If you/someone in your lab is still looking for a PhD for Fall 2025 due to having an offer rescinded, etc. I have funding for up to 2 PhD students in my lab at @Mizzou. Contact me if you're interested in studying California quail social behavior biology.missouri.edu/people/allison…

Results for @NSERC_CRSNG Discovery Grants will be transmitted to the universities today. Congratulations to all the researchers who have been funded.

Earlier this month, I was pleased to represent #YorkU, the academic lead of the @UNITAR Global Water Academy, on a UNITAR-led virtual panel discussion about the barriers to women’s participation in water governance. Learn more: bit.ly/4jayP1n | #SDGMonthCanada

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

💧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. 🔗 To register: shorturl.at/Xl8gE #WWD2025

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
