CNN Anchor and National Correspondent Erica Hill takes a deep dive into the future of Venice, a city threatened by rising sea levels and the millions of tourists desperate to visit while they still can. 

Much of the world fears that climate change and rising sea levels will soon sink the ancient city of Venice, a misconception that is causing millions of tourists to visit each year while they still can. In "Saving Venice," Hill discovers that the more imminent threat to Venetians' way of life is this overwhelming flood of tourists, transforming the city's culture, housing and local economy. Hill speaks with a collective of locals interested in promoting a more ethical tourism industry with respect for Venice's unique and delicate environment. She learns about the innovative ways a new generation of Venetians are working to preserve the city's traditions, mitigate the effects of climate change, and taper the city's dependance on massive amounts of tourists.

"The rich history of Venice is one of innovation, evolution and entrepreneurship," said Hill. "That legacy is being tested now more than ever, but there are sustainable, thoughtful solutions to save this beautiful city, its culture, and most importantly, its community. With unique access to the Venice many visitors don't see, I am hopeful this hour will introduce audiences to a city - and a story - that is also a critical wake-up call for others around the world."

The episode features interviews with local Venetian restauranteurs, artisans, oceanographers, city planners and more. Hill even gets a rowing lesson in the canals of Venice from a competitive rower whose family has been competing in the city for generations.

CNN Senior Correspondent Donie O'Sullivan returns with a new installment in his Emmy® nominated MisinfoNation series as he investigates the rise of extremism in "MisinfoNation: Extreme America."

Over the last two years, O'Sullivan has traveled the country investigating the pervasive surge of misinformation targeting Americans and has reported everywhere from the Republican and Democratic national conventions to Mike Lindell's pillow factory, a QAnon church, and a JFK conspiracy convention. In his new report on the 30-year anniversary of the Oklahoma City bombing, O'Sullivan looks at the changing face of extremism in the United States. Thirty years ago, radical ideas and the search for like-minded extremists took time and effort, but now – with just a click – hate and paranoia is served to millions of Americans every day through algorithms and social media.

"From the pardoning of January 6 rioters to the celebrating of the murder of a healthcare CEO, how Americans are talking about violence is changing," O Sullivan said.  "In this episode we look at how the media we are consuming is radicalizing us."

In "MisinfoNation," O'Sullivan travels across the country meeting far-right extremists with a long history of hate, talks to pardoned January 6 rioters, and encounters a new generation of radicalized Americans justifying the murder of healthcare CEO Brian Thompson.  He examines how the ongoing revolution in technology and information consumption is radicalizing us, meets a UFC fighter turned podcaster who platforms white supremacists, and visits a Texas man helping people print 3D guns at home.

The result of over two years of on-the-ground reporting, Bolduan embeds with those most impacted by America's opioid overdose epidemic. As the crisis enters its "third wave," Bolduan engages with emergency medical technicians, physicians at treatment centers and people struggling with addiction themselves, all seeking new solutions to a decades-old problem. 

"These past two years have been a uniquely powerful and educational experience for our team. I am grateful to all our interviewees who bravely allowed us in and shared their stories," said Bolduan. "We witnessed first-hand the extraordinary challenges that come with breaking free from the cycles of addiction, and I am hopeful this project will illuminate the human element of the crisis and encourage others who are struggling to seek treatment." 

"Fentanyl in America" features remarkably candid and intimate interviews with people struggling with addiction. Pregnant women, families, and even drug dealers reveal to Bolduan the harsh realities of illicit fentanyl, a crisis that has propelled new treatment programs. She rides along with the first emergency medical service in the nation to carry buprenorphine, a treatment for fentanyl withdrawal that a study has associated with a nearly sixfold increase in the odds of engagement with addiction treatment. Bolduan also visits a center providing methadone treatments, where some people must visit every day for their daily dose.

Chief Climate Correspondent Bill Weir returns with an exploration into how human life as we know it is adapting to our changing climate. He seeks answers to how humankind can survive and thrive in an age of heat, drought, flood, and fire. His quest to find the heroes and innovators on the frontlines of this issue takes him across the globe, where he finds heroes building happier, healthier, and stronger communities built to withstand extreme weather in any form it takes.

"When I became a new dad in 2020," Weir said, "I looked down at my son and thought ‘Where will he be safe? 'What kind of shelter will he need? Who is building the smartest, safest, and most resilient communities?' His arrival helped spark this worldwide hunt for inspiration and in the end, I returned with a lot more hope than fear."

From a new "policy of shade" in scorching Phoenix to a floating neighborhood outside of Amsterdam to the rise of disaster-proof construction, Weir finds those on the cutting edge of adapting our way of life. With visits to London and Silicon Valley, he reveals the inventions and startups that have the investment blessing of Bill Gates and Tom Steyer.

He returns to Paradise, California, five years after the deadliest mainland fire in the last century and gets lessons from survivors on how to build a fireproof town with stronger shelter but an even stronger community. And he tours Florida's first solar-powered town, built in harmony with nature and to withstand modern storms. Babcock Ranch has now survived two major hurricanes without flooding or losing power and their design secrets are more relevant than ever.

He visits his alma mater, Lakeside School, an elite all-boys private institute at the time of Gates's enrollment, and a place he credits with his transformation into an engaged student and fanatical computer programmer by the age of 13. It would also be the place where he would befriend his Microsoft co-founder, Paul Allen. After reflecting on his past, Gates discusses his thoughts on the future, including his recent meeting with President Donald Trump, Elon Musk intervening with USAID, and the potential impact of artificial intelligence.

CNN Senior Investigative Correspondent Kyung Lah presents an in-depth look at the unusual star-making K-Pop industry in South Korea. 

K-Pop idol bands have fan bases all over the globe, hugely popular musicians and songs originating from South Korea.  But these bands are molded and created in a way unlike anything else in the music industry. Aspiring young stars take on rigorous vocal, dance and fitness training from early morning to late at night, some even leaving school and living in dorms away from their families. In "K-Pop: A Star is Made" Lah embeds in the strenuous training process of seven aspiring K-Pop stars in a small studio in the heart of Seoul, South Korea when they are just one week away from auditioning for the studio's premiere idol group.

"As a Korean American growing up in Chicago, I never imagined my native language would be streamed across platforms in the US as a multi-billion-dollar industry," said Lah. "It still shocks me to this day. What I wanted CNN's audience is to see and experience how this happened, through the intimacy of the struggle of the K-pop trainees you'll meet in our hour. They're more than perfect young men and women of the TikTok era — they're utterly human, some as young as 14, and as vulnerable as the young fans who listen to them."

The episode features interviews with Amber Liu, Megan Moon and Min who talk about the global impact of this explosive industry, which also comes with international scrutiny for its stars. Lah also speaks with the trainees about the pressure to maintain a certain appearance, and how extreme dieting and plastic surgery are common amongst K-Pop hopefuls.
