There are now significantly more new cases of coronavirus outside China than inside. On the first day of this week there were only 44 new cases in the whole country. Just a few weeks ago that figure was in the thousands. While the authorities have been criticised for their initial slow response to the outbreak, allowing it to spread quickly, since January they have taken unprecedented action to clamp down on the spread of the virus. Whole cities have been put into quarantine and travel restrictions have been imposed on millions of people. New hospitals have been built with lightning speed and huge amounts of money has been spent on testing kits and other technology to fight Covid-19.China has been accused of infringing civil liberties in its fight against Coronavirus but it has also been praised for the extreme public health measures it has taken. So what did the Chinese actually do and can it be replicated elsewhere?Presenter: Tanya Beckett Producer: John Murphy(Photo: A man talks through a barricade wall built to control entry and exit to a residential compound in Wuhan, Hubei province, China.Credit: Getty Images)

Climate change models have been a key tool to project what could happen with global warming in the future. But there’s a debate in the scientific community and some are saying too much emphasis has been put on the worst-case scenarios. Others argue that the impacts of climate change are too unpredictable and all scenarios, even the most serious, less likely ones, need to be kept on the table.All agree, though, that human-induced climate change is happening and that even the most likely projected temperature increases will be serious and potentially very damaging.Presenter: Ruth Alexander Producers: Xavier Zapata and John Murphy(An iceberg that broke away from a Glacier in the Southern Patagonian Ice Field which is experiencing high rates of melting.

We have a great capacity to ignore facts and only believe what we want to believe – particularly if those facts clash with our convictions. Why is that and is it getting worse? It’s an area that is being intensely studied by psychologists, political scientists and neuroscientists.Ruth Alexander explores why we ignore facts, even if it’s bad for us. Though she also hears how, in some circumstances, it can be good for our mental health. But our casual attitude towards facts can have serious consequences. According to experts this is happening across the world, in politics, in health and in our daily lives. This behaviour is not the preserve of any particular political group – everyone does it when it suits them.

Britain is trying to make multiple trade deals since leaving the EU. Some negotiations between countries have lasted for years. The breakdown in the World Trade Organization, the changing nature and complexity of world trade and a general lack of trust between nations means it could be a very drawn out process. Presented by Tanya Beckett.

The Coronavirus outbreak in China has been declared a public health emergency of international concern. It is raising fears of a global disease pandemic. In the past viral infections have killed millions. Possibly the worst ever pandemic was the 1918-19 flu, which spread just as the First World War was coming to an end. Estimates of the death toll now range between 50 and 100 million. At the upper range that means it was more deadly than both World Wars put together. So could another pandemic emerge today and kill millions? How might it happen and how prepared are we to confront it? The world is a very different place to 100 years ago. Scientific and public health advances do mean some parts of the world are more prepared but our ways of living could make us more susceptible to a new virus.Speaking to a leading virologist, a disease modeller, a public health policy expert and a senior African health official, Ben Chu asks where the virus threat might come from, how fast it could spread, what containment policies work and whether the world is ready.Presenter: Ben Chu Producer: John Murphy (image: Scientist working with a dangerous virus in the laboratory.

Could a new law in India be a step towards making Muslims second class citizens? The government says the Citizenship Amendment Act is a humanitarian law giving protection for people escaping religious persecution.

How did Trump’s personality and way of dealing with people lead to a trial in the Senate? The answer involves Trump’s long standing belief in conspiracy theories, his transactional way of doing business, the revolving door of staff turnover at the White House and his admiration for Russian president Vladimir Putin.

On 25 July 2019, the President of the United States made a phone call to the recently-elected President of Ukraine - congratulating him on his party’s election victory. What Donald Trump said in that call to Volodymyr Zelensky has ended up threatening his own presidency, triggering the impeachment of the president. Donald Trump says his interest was in rooting out corruption. Meanwhile Joe Biden’s role in Ukraine was to do the same - root out corruption. The Inquiry asks why Ukraine has such a corruption problem. Presented by Ruth Alexander.(A Ukrainian flag flies in Independence Square in Kyiv, the capital of Ukraine.

President Trump’s decision to assassinate Qasem Soleimani came as a shock to America’s foes and allies alike. He was Iran’s top general and has been described as one of the country’s most powerful figures, second only to the Supreme Leader Ayotollah Ali Khamenei. He was, effectively, head of Iran’s foreign policy. He’s been credited as being instrumental in the fight against ISIS but has also been accused of arming and supporting terror groups. But why did Donald Trump order his death?Presenter: Tanya Beckett Producer: John Murphy (Image: Lieutenant General Qasem Soleimani / Photo handout from the Iranian Supreme Leader's office)

What is the chance of the human race surviving the 21st century? There are many dangers – climate change for example, or nuclear war, or a pandemic, or planet Earth being hit by a giant asteroid.Around the world a number of research centres have sprung up to investigate and mitigate what’s called existential risk. How precarious is our civilisation and what can be done to stop a global catastrophe? David Edmonds talks to four expert witnesses to try and find the answer.(Apocalyptic landscape.
