How does Canada plan to reduce its Greenhouse Gas Footprint?

In a previous blog post, we took an in-depth look at Canada’s annual greenhouse gas (GHG) emissions [1]. The most recent GHG census pegged total annual emissions at 722 Mt (million metric tons) [2]. This is a very large number considering Canada’s relatively small population, meaning our per capita emissions rank among the highest in the world [3]….

Where Do Canada’s Greenhouse Gas Emissions Come From?

Earth’s atmosphere is made up of many different gases, some of which are “greenhouse” gases. They are called that because they effectively act like a greenhouse or a layer of insulation for Earth: they trap heat and warm the planet. For the past couple of hundred years, human activities (such as burning coal to generate…

The Venus Paradox

The planet Venus is hot. Really hot. Its average surface temperature is over 460 °C, compared to Earth’s 14 °C. This might not come as a surprise: Venus is, after all, much closer to the sun than we are. So, the paradox is not that Venus is so hot, it’s that Venus is also so…

Keeling’s Curve

    How do we know for sure that human activities are resulting in an increase in global carbon dioxide concentrations? The answer involves accurately measuring the amount of CO2 in the air, a seemingly simple problem that’s actually deceptively complex.   If you tried to record the concentration of carbon dioxide near your home,…
