Day 65: The Carbon cycle – The Impacts (Part 3)

Disrupting the carbon cycle has serious impacts on the planet. Something as “little” as offsetting the natural flow of carbon affects everything that is linked to carbon (in other words, all life on Earth). Let’s take a look at how pumping more carbon dioxide into the atmosphere and the ocean impact the planet. Continue reading

Day 64: The Carbon Cycle – how do humans affect it? (Part 2)

Like I mentioned in Part 1, the scary part about analyzing the carbon cycle is realizing how much humans are affecting it. If we look at the diagram of the carbon cycle, one of the ways carbon transits from sphere to sphere is from the subsurface (fossil fuels) to the surface by extraction, then to the atmosphere by burning the fossil fuels. The atmosphere also exchanges with the hydrosphere, so part of the carbon that we burn is then absorbed by the ocean. Continue reading

Day 19: What’s all this fuss over 350 ppm of carbon dioxide?

This is a chart of the carbon dioxide levels in the atmosphere over the last 800 000 years, which is as far back as we can trace them. To put you in perspective, in the last 800 000 years, the Earth had already been through many ice ages and the species Homo sapiens was created.
