My grass is now 100% dead. So we're half my bushes and shrubs at my house. I can't even grow a vegetable garden for the past few years because of the heat, it's just too intense. Even tomatoes don't grow.

Hank Hill must be in crisis right now

We made the decision to not even try watering the lawn this year. Guess it was a good call.

My guess would be Ice Cores.

From Wikipedia:

"An ice core is a core sample that is typically removed from an ice sheet or a high mountain glacier. Since the ice forms from the incremental buildup of annual layers of snow, lower layers are older than upper ones, and an ice core contains ice formed over a range of years. Cores are drilled with hand augers (for shallow holes) or powered drills; they can reach depths of over two miles (3.2 km), and contain ice up to 800,000 years old.

The physical properties of the ice and of material trapped in it can be used to reconstruct the climate over the age range of the core. The proportions of different oxygen and hydrogen isotopes provide information about ancient temperatures, and the air trapped in tiny bubbles can be analysed to determine the level of atmospheric gases such as carbon dioxide. Since heat flow in a large ice sheet is very slow, the borehole temperature is another indicator of temperature in the past. These data can be combined to find the climate model that best fits all the available data.

Wouldn't the Hudson Bay beach front be submerged too? Or is their beach a few meters above the water?
