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.

Investing in green energy, holding large corporations accountable for their pollution, stopping pipeline and oil extraction initiatives -- these are non-negotiable actions to protect the planet, but they are still just the bare minimum, say climate activists Xiye Bastida and Shiv Soin. In conversation with radio researcher Latif Nasser, Bastida and Soin share their list of six crucial climate demands for world leaders -- and discuss how we all can get involved. (This segment was part of TED's Countdown Global Livestream on October 30, 2021.)

Africa needs new energy sources to fuel its development, but the continent should invest in renewable energy instead of cheap, polluting alternatives like coal, says climate inclusion activist Chibeze Ezekiel. He tells the story of how he worked with local communities in Ghana to halt the construction of the country's first coal power plant -- and encouraged the government to prioritize investments in renewable energy instead. "Development and clean, breathable air should not be mutually exclusive," Ezekiel says.

It's time to give paper passports a digital upgrade, says entrepreneur Karoli Hindriks. Looking to Estonia's technology-driven government for inspiration, she envisions a world where immigration is no longer hindered by bureaucracy and needless repetition. Travel with her to a future beyond borders where universal digital passports replace paper ones -- and where outdated systems stop wasting our time and money.

Government deficits have gotten a bad rap, says economist Stephanie Kelton. In this groundbreaking talk, she makes the case to stop looking at government spending as a path towards frightening piles of debt, but rather as a financial contribution to the things that matter -- like health care, education, infrastructure and beyond. "We have the resources we need to begin repairing our broken systems," Kelton says. "But we have to believe it's possible."

We live in a call-out culture, says activist and scholar Loretta J. Ross. You're probably familiar with it: the public shaming and blaming, on social media and in real life, of people who may have done wrong and are being held accountable. In this bold, actionable talk, Ross gives us a toolkit for starting productive conversations instead of fights -- what she calls a "call-in culture" -- and shares strategies that help challenge wrongdoing while still creating space for growth, forgiveness and maybe even an unexpected friend. "Fighting hate should be fun," Ross says. "It's being a hater that sucks."
