How do we remove carbon dioxide from our planet’s atmosphere? What innovations are being explored? And why is it essential that we develop these solutions?
“Carbon dioxide (CO2) is a greenhouse gas that traps heat and warms the planet. Because of the burning of fossil fuels, the amount of CO2 in the earth’s atmosphere is higher than it has been in at least one million years.”
“Nature mitigates carbon and reduces some of the effects of climate change: Plants, trees, and algae in the ocean turn CO2 into oxygen through photosynthesis, and the ocean absorbs and stores CO2 in ocean sinks.”
“But nature cannot withstand the rising levels of human-produced emissions. Consequently, Earth and the people on it have experienced the effects of climate change, such as more frequent and intense weather events.”
Take a look at some of the ideas that scientists, engineers, and policymakers are pursuing to help combat climate change. This animation from the Caltech Science Exchange team is a good introduction.
