With more heat waves in our future, researchers say we need to look at clean cooling
As we head into winter, it's unlikely Canadians are thinking about heat waves. But before we know it, summer will be upon us again, as will more extremely hot days. The challenge is, how do we stay cool in the future without contributing to climate change?
What are the private flights of the 1% doing to the planet? The numbers are in
When it comes to aviation in general, it contributes roughly 2.5 per cent of all CO2 emissions and has thus far contributed to roughly four per cent of global warming. But just how much CO2 emissions are these private jets emitting? A lot, according to a new study.
