The plan to suck CO2 out of the atmosphere and use it to rebuild Earth’s coasts

Though the effects of climate change are becoming more apparent and threatening every year, the world’s most powerful nations are still not doing enough to combat the threat. We’re running out of time to change our way of life to meet this challenge, and some world leaders refuse to even admit there is a problem.

Even if we adopt much more aggressive policies to fight climate change sometime in the next few years, the amount of CO2 we’ll have already pumped into the atmosphere will continue to contribute to sea level rise, extreme weather events, and more. According to the United Nations’ Intergovernmental Panel on Climate Change (IPCC), we may need to invest in literally sucking CO2 out of the atmosphere to avoid climate change’s worst effects.

This technology, known as carbon capture, is still developing. There are multiple ideas for how it could be done — each with its own set of pros and cons. For example, we could suck CO2 out of the atmosphere and sequester it deep inside the Earth, but there are concerns that it could still leak out. We could also turn it into fuel, but doing so would ultimately mean we’re still burning carbon, so it’s essentially just carbon neutral, not carbon negative.
