Some things are more important than our national holiday (lots of things actually). You can see one of them in this BBC video that features Dr. Maggie Aderin-Pocock demonstrating how excess greenhouse gases let loose by human activity -- like CO2 from our burning of oil and other fossil fuels -- are turning up the temperatures on the planet. Only 2:20 minutes.
We humans and the rest of contemporary creatures didn't evolve to live in a much hotter world. Trouble ahead of we can't kick the habit.
