Recently back from the COP26 UN climate conference in Scotland, former Icelandic presidential candidate Halla Tómasdóttir sums up the outcomes of the gathering, the progress she saw and the work that's left to be done this way: "The most difficult work of our lifetimes has to happen in the next few years." In conversation with TEDWomen curator Pat Mitchell, Tómasdóttir urges us all to recognize our power and to use our voice, vote and wallet to catalyze meaningful climate action.
