As the days shorten and the temperature drops, the inhabitants of Nunavik, Quebec prepare to face the approaching arctic winter. Watch as muskoxen fatten up, ptarmigans hunt for berries, and Inuit make use of the last warm days of the year.
In this final episode we complete our journey, travelling back from the March equinox to the end of June. Kate Humble is in the Arctic at a place where spring arrives with a bang, whilst Helen Czerski chases a tornado to show how the earth's angle of tilt creates the most extreme weather on earth.
This episode focuses on the Jurassic period, a time when the first giant killers stalked the Earth and lurked in the seas; a time when the slightest advantage meant the difference between life and death. In North America the iconic allosaurus, an ambush hunter with a lethal bite, dominated. Not even the heavily-armoured stegosaurus was safe from this killer, and incredible evidence reveals a glimpse of a vicious battle between these two giants. Life in Jurassic oceans was no easier; in 2008, a fossil was dug out of a frozen island high in the Arctic. It was a colossal marine reptile, twice as big as most ocean predators, at 15 metres long and weighing about 45 tonnes. This was Predator X. Its skull alone was nearly twice the size of a tyrannosaurus rex's, and its bite force unmatched by anything in the Jurassic seas. The balance of power between predator and prey is a fine one, as prey continually evolves different ways to avoid predators. But for the most successful and enduring predators, the battle to survive has always been tipped in their favour.
Showcasing footage from around the world after an unprecedented year, “The Year Earth Changed” is a timely documentary special that takes a fresh new approach to the global lockdown and the uplifting stories that have come out of it. From hearing birdsong in deserted cities and seeing whales in Glacier Bay, to meeting capybara in suburbs across South America, people worldwide have had the chance to engage with nature like never before. In this documentary special, viewers will witness how the smallest changes in human behavior – reducing cruise ship traffic, closing beaches a few days a year, identifying more harmonious ways for humans and wildlife to coexist – can have a profound impact on nature. The documentary, narrated by David Attenborough, is a love letter to planet Earth, highlighting the ways nature’s resiliency and ability to bounce back can give us hope for the future.
