This article discusses giant lava flows in the Earth's past that caused mass extinction events by, guess what, causing enormous quantities of CO2 to be liberated into the atmosphere. It's a great look at the actual geological mechanics behind these events, how scientists have been discovering those mechanics, and how they know that the eruptions and mass extinctions are related.
While we don't really have to worry about any of these lava flows in our lifetime since they occur on a geologic timescale, I found the last 3 paragraphs troubling:
We're definitely on course for bad things to come. I think not acting on our effect on Earth's atmosphere is ignorant, arrogant, and will eventually bite us in the ass. I'm not sure how we go about doing it, either; so much of our world's society is dependent on using things that generate pollution. Mining metals for our phones, using electricity to cool and heat our homes, burning gas to run cars and trucks. It's alarming to see the trends be ignored or erroneously refuted by those in power.
In terms of energy consumption, I feel that people are at least taking steps in the right direction in terms of wind and solar. And there is research on how to sequester CO2 from the atmosphere and how to scrub CO2 from factory exhaust using algae. We just need the political will to support these universally beneficial projects and research avenues.
