The world’s average temperature has increased 1°C in just the past 100 years. Extreme weather and rising seas are already causing global unrest, and many scientists believe that if we cannot curb planetary warming, it could pose an existential threat to human civilization. As it becomes clear that emissions reductions alone may not be enough to avoid dire effects of climate change, a growing collective of scientists and engineers is developing technologies that could cool the planet—from geoengineering our atmosphere to reflect sunlight, to sucking carbon dioxide right out of the air, to enlisting forests to do the job for us. NOVA joins scientists and skeptics alike to examine the potential—and the peril—of the sometimes-controversial technologies that could help us combat a looming threat.

Pioneer of the Shinkansen, The (2016)
Shinji Sogo was the 4th president of Japanese National Railways. With imagination and determination, he made sure that the Shinkansen bullet train service started in time for the 1964 Tokyo Olympics. The news brought attention from around the world and revived the railway industry. It also laid the groundwork for high-speed railways being planned and built in Europe, the US and Asia today. This program examines rare documents and firsthand accounts of how Sogo's leadership brought the ambitious Shinkansen project to fruition.

Jacques Lacan Speaks (1982)
Typically controversial speech by psychoanalyst/philosopher Lacan is disrupted by a student, ridiculing such public intellectuals. Lacan refuses to allow security to haul off the student, lets him speak and incorporates such criticisms into his presentation. The packed performance took place at the Catholic University of Louvain on October 13, 1972, with Lacan interrelating death, language, love, alienation, paranoia and life. His talk is followed by a probing interview of Lacan on his concepts of psychoanalysis, conducted by the director, Belgian documentarian Francoise Wolff. One of only 2 known filmed appearances by Lacan, both by Wolff, who also made documentaries of Albert Einstein and Alexander Solzhenitsyn.

Saving the Amazon (2020)
The Amazon is one of the most precious natural habitats in the world and plays a vital part in regulating the planet's temperature. So when alarming pictures emerged last year of the Amazon on fire, the world was shocked. These fires were so big they could be seen from space, leaving many to ask how could this have happened? Why wasn't the forest being protected? Four Corners takes you on an epic journey on the frontline to preserve the world's largest tropical rainforest. Indigenous tribes, scientists and activists are fighting back. Sophie McNeill reports.

Flu That Killed 50 Million, The (2018)
It is 1918 and the end of WWI. Millions have died, and the world is exhausted by war. But soon a new horror is sweeping the world, a terrifying virus that will kill more than fifty million people - the Spanish flu. Using dramatic reconstruction and eyewitness testimony from doctors, soldiers, civilians and politicians, this one-off special brings to life the onslaught of the disease, the horrors of those who lived through it and the efforts of the pioneering scientists desperately looking for the cure.
Narrated by Christopher Eccleston, the film also asks whether, a century later, the lessons learnt in 1918 might help us fight a future global flu pandemic.

7.7 Billion People and Counting (2020)
According to the UN, it is predicted that the human population could reach ten billion people by the year 2050. For broadcaster and naturalist Chris Packham, who has dedicated his life to championing the natural world, the subject of our growing population and the impact it is having on our planet is one of the most vital – and often overlooked – topics of discussion in an era of increasing environmental awareness.
Chris is worried that a world of ten billion may simply be too many people for the earth to sustain, given the impact 7.7 billion humans are already having. Travelling around the globe in search of answers to difficult and sometimes controversial questions, Chris investigates why our population is growing so rapidly, what impact it is having on the natural world, and whether there is anything that can be done.
Chris travels to Brazil to discover a megacity on the verge of running out of water and an industry expanding to feed our growing numbers – with dire consequences for biodiversity. In Nigeria, a country set to become the third most populous nation on earth by 2050, overtaking the United States, Chris visits an extraordinary community surviving against the odds and a school that might hold the answer to a future fall in the birth rate. Back home in Britain, Chris interviews Sir David Attenborough – like Chris, he is a patron of the charity Population Matters. Chris also examines the role of falling birth rates around the world, the impact of an aging population, and meets a couple who are struggling to get pregnant through IVF.
With interviews from several population experts, Chris's focus ultimately turns to the impact our levels of consumption are already having, and asks whether the world can rebalance to accommodate the needs of over two billion more people.

250 Million Pound Cancer Cure, The (2019)
Proton beam therapy is the one of the most technologically advanced though expensive cancer treatments in the world - but it has the potential to save the lives of children with otherwise incurable cancers.
Over two years, Horizon follows the engineers, scientists and medics as they race to build two new centres, one at the Christie Hospital in Manchester and one at University College Hospital in London, as well as following as the first children awaiting the lifesaving treatment. This is one of the most complex challenges the NHS has ever attempted.
At the cutting edge of particle physics, proton beam therapy involves splitting hydrogen atoms to create a beam of protons travelling at two-thirds the speed of light, which target tumours with millimetre precision. But doing this in the heart of two of our biggest cities is no easy feat. The process generates so much radiation it needs to be housed in a maze-like nuclear bunker, with walls four metres thick. 2,000 tonnes of precision instruments are installed - more than four jumbo jets worth - and it all has to work perfectly.
This special BBC Two programme goes behind the scenes on the £250 million cancer cure - from digging the biggest, widest hole ever to exist in London to the treatment of the first patients in the UK.
