1) “Greta Thunberg: A Year to Change the World” (PBS) and “2040” (CW), both 8 p.m. Thunberg, now 18, planned to take a school year (2019-20) off and travel the globe, studying and speaking about climate change. Huge problems followed, including the pandemic, but this three-hour film remains uplifting and idealistic. That’s one of two Earth Day specials on broadcast networks; “2040” (shown here) offers an optimistic view, looking at current programs and envisioning an improved climate in 20 years. Read more…

1) “Snowfall” season finale, 10 p.m., FX, rerunning at 11. Some fierce collisions have been propelled by two things: A reporter (tipped by Franklin’s father) wrote about Teddy’s CIA guns-for-drugs scheme; also, Leon accidentally killed the niece of Manboy, a rival gang boss. (Franklin, Leon and Manboy are shown here.) Last week, Teddy killed the reporter after a car crash; Franklin killed Manboy and his gang. Here are the aftershocks, some quiet and some not. This would be a great series finale, but “Snowfall” will return. Read more…

1) “Cruel Summer” debut, 9 and 10 p.m., Freeform. Here is a remarkable performance by young Chiara Aurelia – virtually a triple role, all within one character. We meet Jeanette as a shy and likable teen (shown here) who secretly envies the beautiful Kate (Olivia Holt). A year later, she has Kate’s life and boyfriend; a year after that, she’s widely hated. Bouncing between the three summers, we slowly learn her actions (or inaction) changed everything. And we see the mixed impulses that can live inside one teen. Read more…

1) “American Experience: American Oz,” 9-11 p.m., PBS. After a blissful childhood, Frank Baum dreamed big, often with his dad’s financial backing. He raised thoroughbred chickens; he wrote, produced and starred in a touring musical. In South Dakota, he tried a high-end store and then a newspaper that went from feminism to proposing Indian annihilation. He failed often and then, in his 40s, succeeded with children’s short tales … a window-dressers’ magazine … and “The Wizard of Oz,” a classic book that became an immensely popular movie (shown here).

1) Academy of Country Music awards, 8-11 p.m., CBS. Miranda Lambert will open the show, singing “Drunk” with Elle King (they’re shown here); she’ll also link with Jack Ingram and Jon Randall for “In His Arms.” Her ex-husband Blake Shelton will celebrate the 20th anniversary of “Austin” and also do “Minimum Wage.” From three Nashville locations, others include Carrie Underwood (with gospel great CeCe Winans), Dierks Bentley, Luke Combs, Kane Brown, hosts Brad Paisley and Mickey Guyton, and many more.
