Genuine question for any

experts; does Lake Huron actually ice shelves? An ice shelf -typically 100s of meters thick and thousands of km in area - is the floating extension of a glacier or ice sheet. This sounds more like a chunk of lake ice that broke off.

Incredible heat in the Mediteranean with sea sfc departures up to 7C (13 F) above normal! While +13F is not unusual for air temps, for large water bodies it's ludicrous. Marine heateaves in the Med are now 3X more likely than the 1980s due to climate change - CC can explain 90% of this increase.
