THE RESISTANCE – After Russia's unprovoked invasion of Ukraine, people were faced with the decision to flee or fight. Correspondent Scott Pelley reports from the capital city of Kherson, a mile from ongoing Russian shelling, and speaks with civilians who resisted the occupation about how they defended their region. Nicole Young is the producer.RED AND GREEN –Correspondent Bill Whitaker reports from the conservative state of Wyoming and meets with its surprisingly climate-crusading Republican governor, Mark Gordon. Currently in his second term, Gordon has set a goal to make Wyoming not just carbon-neutral but carbon-negative in CO2 emissions. It's an audacious idea, since Wyoming is the nation's largest coal producer by far. Despite heat from climate change deniers in his own party, Gordon tells Whitaker he's sticking to his goal, and to his "all of the above" approach to energy. Rome Hartman is the producer.NOVAK DJOKOVIC –At 36 years old, Novak Djokovic is one of the most dominant athletes in professional sports, having captured 24 major tennis singles titles, more than his longtime rivals Rafael Nadal and Roger Federer.
