The Ahr Valley flood Nov 04, 2021

Show notes

The worst effects of climate change are often framed as a problem for the future. But for some, the worst has already happened. As world leaders gather in Glasgow to talk about how to bring down emissions, Assignment tells the story of three places which have been at the sharp end of extreme weather events. Germany's Ahr Valley was a picturesque chain of ancient towns and villages along a small, beautiful river - a region popular with tourists, famous for its wine production. Then on one terrifying night in July, the water rose with little warning, engulfing almost every house. It was the worst flood in the valley for 700 years. People fought their way through the water, clung for hours to roofs and trees before they were rescued. More than 100 lost their lives. Almost all bridges were destroyed, most homes left uninhabitable, businesses ruined. Even now, many have been unable to return. Tim Whewell travels through the valley, meeting some of the victims as they recall how they struggled to escape the flood, remember the friends and relatives they lost and try to rebuild their lives.

A Geochemical HIstory of LIfe on Earth: 5. The Anthropocene Oct 31, 2021

Show notes

Could human engineering stabilise the Earth's climate and chemistry in the long term? Tim Lenton of Exeter University explains why the Gaia hypothesis is the key to understanding the future of life on Earth. But what about life beyond Earth? Justin Rowlatt speaks to astronomer Lisa Kaltenegger - a hunter and explorer of planets outside our solar system - and to the science fiction author David Brin. Plus paleobiologist Jan Zalasiewicz describes what might remain of human civilisation in the geological record 100 million years hence.

The Story of Aids: 4. The end of an epidemic? Oct 30, 2021

Show notes

When President Thabo Mbeki came to power in South Africa in 1999, the country was gripped by an HIV-Aids epidemic - and the president's decision to question scientific evidence, and reject the use of life-saving drugs only made the situation even more dire. But activists and medical staff were ready to fight the government's position by any means.

Climate: Animals under threat Oct 30, 2021

Show notes

The changing planet is threatening a number of vulnerable and endangered species, and host Nuala McGovern hears from three experts on polar bears, snow leopards and bumble bees on why we should all care about what is happening to all animals. We learn about the importance of pollinators to healthy ecosystems. We also hear from a sheep farmer in Australia and a vegetable and fish farmer in Nigeria about how climate change is affecting food security and the issues they have in common on two different continents.

Ros Atkins on: The US and China’s climate commitments Oct 30, 2021

Lytton Burns Oct 28, 2021

Show notes

The worst effects of climate change are often framed as a problem for the future. But for some, the worst has already happened. As world leaders prepare to gather in Glasgow to talk about how to bring down emissions, Assignment tells the story of three places which have been at the sharp end of extreme weather events. In June, the Canadian village of Lytton smashed national heat records three days running, reaching an astonishing 49.6 degrees Celsius. Then, it burned to the ground. This documentary, the first in the series, is a vivid portrayal of a place in the crosshairs of climate change, where people don’t just have to imagine the future. They’re now figuring out how to build it.

A Geochemical History of Life on Earth: 4. The great chemistry experiment Oct 24, 2021

Show notes

Justin looks at the period since the meteor that wiped out the dinosaurs, which had seen a steadily cooling climate - until we humans turned up. What can the last 66 million years teach us about the likely consequences of climate change? And can our species make the next big evolutionary leap needed to tackle it? Adrian Lister of the Natural History Museum gives Justin a fossilised tour of how the Earth's fauna adapted to this changing climate.

The Story of Aids: 3. Aids denialism in South Africa Oct 23, 2021

Show notes

When Aids began to emerge in the USA and Europe in the 1980s, South Africa was a fractured country, divided by Apartheid. During this time, the ruling National Party seemed disinterested in preventing a disease which was mainly affecting black people and gay men. The fall of Apartheid and the inauguration of President Nelson Mandela didn't improve the situation - the country's first black president was overwhelmed with rebuilding a fragile nation, and the problem of HIV-Aids was pushed down the list of government priorities. But perhaps the most malignant factor shaping South Africa's response to the Aids crisis, was the influence of President Thabo Mbeki, who bought into conspiracies and misinformation, propagated by a fervent Aids denialism movement.

Climate: Changing seas Oct 23, 2021

Show notes

As world leaders, scientists and activists prepare for the UN climate change conference in Scotland, host Nuala McGovern hears how sea level rise is affecting islands in the Caribbean Sea, the Atlantic and Pacific Ocean.
