🐟 Dive into the tiny world that’s quietly shaping Lake Huron’s recovery story! At the 40th annual Pow Wow in Cape Croker, our team set up an interactive booth exploring nutrients → phytoplankton → zooplankton → the comeback of the whitefish (dikameg). 👉 Check out the full story: tinyurl.com/mpkthyfv
Pow Wow Booth Engages Public on Lake Huron’s Changing Food Web — Centre for Ecosystem Management

Climate tipping points are being crossed, scientists warn ahead of COP30
Global warming is crossing dangerous thresholds sooner than expected with the world’s coral reefs now in an almost irreversible die-off, marking what scientists on Monday described as the first “tipping point” in climate-driven ecosystem collapse.
