Saving Planet Earth: Fixing a Hole
8pm, Channel 4
As the sea ice retreats, the glaciers shrink and the deserts expand, it is good to watch a programme that has something positive to say about humans’ ability to address the error of their destructive ways. When scientists discovered in the 1970s the damage that CFCs were doing to the ozone layer – which protects the Earth from ultraviolet radiation – their warnings fell on deaf ears. This is the surprising story of how two unlikely eco-warriors united nations and averted an apocalypse. Mike Bradley
A Year in the New Forest
7pm, Channel 4
Another chance to reconnect with nature in a final visit to the New Forest, where an unexpected heatwave results in the region’s hottest early summer for decades, sparking a population boom in the insect world. While the ponies, cattle and deer fawns are plagued by swarms of biting pests, rare species of butterfly prosper. MB
Blind Date
8pm, Channel 5
In the most Paul O’Grady-esque twist, the latest series of the dating show bows out with Jordan the dog lover choosing between three women who also bring their pets to the studio. Expect pooch puns, O’Grady’s trademark charm and a little pet-based chaos, plus last week’s potential partners reporting back. Hannah Verdier
Cardinal: Blackfly Season
9pm, BBC Four
A treat awaits fans of the Canadian psychological thriller in this finale, as detectives Cardinal and Delorme make the link between evidence from a new crime scene and the murder in the cave. This prompts a race against time to find mad dog Ray and stop him from killing Terri and her brother. MB
Celebrity Big Brother
10pm, Channel 5
Another year, another batch of “celebrities”. Unlike Love Island, CBB now predicates itself on the tension between has-beens and not-quite-beens, to Chris Morris-like effect. Rogue trader Nick Leeson and Cheers star Kirstie Alley are among the housemates this year. Hannah J Davies
Trevor Noah: African American
10pm, Comedy Central
Viewed as a surprise hire when he became the Daily Show host in 2015, Noah has since channelled his kinetic scepticism into ratings growth. This confident 2013 standup special sees him unpacking his experiences of first arriving in the US, with some Obama quips that now seem almost wistful. Graeme Virtue
Film choice

In breezes the passionate flurry of Debra Winger’s American poet Joy Gresham, with son Douglas, attracted by his Narnia tales. Richard Attenborough directs. Paul Howlett
