At the virtual Leaders’ Climate Summit on Thursday, climate czar John Kerry made the claim that even if a goal of net-zero emissions is achieved, carbon dioxide will still need to be removed from the atmosphere.
Kerry spoke through a screen as the summit was held on a virtual format, saying, “Even if we get to net zero, we still have to get carbon dioxide out of the atmosphere. This is a bigger challenge than a lot of people have really grabbed onto yet.”
