While it would be foolish to ignore the increasingly alarmed warnings of scientists, there is reason to hope.
First, because hope is a political choice. No one ever takes action unless they choose to believe things can be turned around. But second, because humans are incredibly ingenious tool-making animals, and some of the smartest among us are hard at work finding tech tools that can help us avoid climate catastrophe.
Which isn’t to say we can keep on spewing CO2 into the atmosphere at our current rate and invent our way out of the problem. Experts agree on that. But an increasing number of them have also come around to the idea that technology to capture carbon out of the atmosphere or eliminate it as a byproduct in industrial processes will be an essential piece of the puzzle.
