Kirk Johnson

Renowned paleontologist Kirk Johnson takes us on an epic adventure through time at the polar extremes of our planet. Following a trail of strange fossils found in all the wrong places—beech trees in Antarctica, hippo-like mammals in the Arctic—Johnson uncovers the bizarre history of the poles, from miles-high ice sheets to warm polar forests teeming with life. What caused such dramatic changes at the ends of the Earth? And what can the past reveal about our planet’s climate today—and in the future?

The heatwave of 2003 remains etched in our memories. We remember an angry emergency doctor, crowded hospital corridors, and a health minister in a polo shirt who seemed completely out of touch with reality. Between August 1 and 20, 2003, the heatwave claimed 15,000 lives. One in three victims lived in the Ile-de-France region, which was hardest hit by this deadly heatwave. This tragedy revealed many shortcomings. First, the lack of preparedness of the public authorities to deal with such a health crisis. Second, the way in which the elderly are treated. Climatologists estimate that from 2050 onwards, the summer of 2003 will be the norm. Hyper-urbanization, poor insulation in homes, and a lack of green spaces are all factors that exacerbate the effects of high temperatures.

Darwin's great insight – that life has evolved over millions of years by natural selection – has been the cornerstone of all David Attenborough’s natural history series. In this documentary, he takes us on a deeply personal journey which reflects his own life and the way he came to understand Darwin’s theory.

A documentary about the 1999 discovery of a Mastodon skeleton in a Hyde Park backyard.

When a huge meteorite crashed into the earth 66 million years ago and caused the disappearance of the dinosaurs, some of the planet’s tiniest species survived the cataclysm, and—against all odds—eventually became some of the greatest giants to ever roam the earth. From the poles of the planet to the belly of the equator, this documentary sheds new light on four giant animals that are still a great mystery to science today: the Titanoboa snake, the Megalodon shark, the giant rhinoceros and the giant sloth.

The discovery of a giant crater in the floor of the Gulf of Mexico is a step closer to solving the question if an asteroid ended the age of dinosaurs.

Thule, Greenland, also called Qaanaaqis, one of the northernmost towns in the world. As the climate warms and the ice caps begin to melt, the gentle balance of life for the people of this community is in jeopardy. On the other side of the globe, the melting ice caps are raising sea levels around the Polynesian island nation of Tuvalu, threatening to wipe the island right off the map. Though a world apart, these two communities are intricately connected as environmental balance begins to tip and traditional ways of life are threatened.  'ThuleTuvalu' is a stunning documentary addressing the high price of a hundred years of development and how two very different communities are now bound together in facing an uncertain future.
