Hard Numbers: Lebanese riot, Czech pirates surge in polls, China blocks Signal, Brazil gets (another) health minister

Hard Numbers: Czech pirates surge in polls, China blocks Signal, Lebanese riot, Brazil get (another) health minister

15,000: Lebanese protesters rioted in Beirut on Tuesday after the value of the country's currency on the black market plunged to about 15,000 per US dollar. That's a third of what it was two weeks ago and a tenth of its value in late 2019, when Lebanon's latest currency crisis and economic collapse started.


22: For the first time in its history, the Pirate Party is leading voter opinion polls in the Czech Republic with 22 percent. The Pirates, popular among young people, became a major player in Czech politics during the 2019 street protests against Prime Minister Andrej Babiš, and have benefited from the government's poor handling of the pandemic. General elections are due this fall — ahoy Pirates!

510,000: China has blocked Signal. No, not us, but rather the last encrypted messaging app that was still accessible in the country without using a virtual private network to get around China's "Great Firewall" of internet censorship. Before it was taken offline on Tuesday morning, Signal had been downloaded more than 510,000 times in China on the iOS app store.

4: Brazil, with the world's second highest COVID death toll, has now had four health ministers since the pandemic began. Dr. Marcelo Queiroga, a cardiologist, replaces army general Eduardo Pazuello, widely blamed for the country's slow vaccine rollout and oxygen shortages in hard-hit Amazonas state (which forced local hospitals to import oxygen canisters from neighboring Venezuela).

A sector that's rapidly expanding, domotics - domus (home) plus robotics - are smart houses that manage temperature and lighting to minimize wasted electricity. For example, smart thermostats sense your presence and set the temperature according to your needs, saving 20% a year on heating bills. Watch this episode of Eni's Energy Shot series to learn how domotics save money and increase a home's value.

Even if the US, Europe, China, and India reduce carbon emissions at the rate they've promised, much climate damage has already been done. That shouldn't stop these and other countries from doing all they can to meet their net-zero emissions targets, but they also better start preparing for a world of people on the move.

Climate change will displace an unprecedented number of people in coming years, creating not just a series of humanitarian crises in many parts of the world, but lasting political, economic, and social upheaval as those of us who live on higher ground try to find a sustainable place for these climate refugees to live.

Listen: In a wide-ranging interview with Ian Bremmer, Pulitzer Prize-winning climate journalist Elizabeth Kolbert assesses the current state of the climate crisis and answers a simple question: how screwed are we? And as the climate continues to warm at a record pace, she unpacks some of the more extreme climate solutions that some increasingly desperate nations are starting to consider. Such measures may sound like stuff of science fiction (see: injecting sulfur particles into the atmosphere or shooting millions of tiny orbital mirrors into outer space) as times become more desperate, their appeal is growing. Can we fix the planet the same way we broke it?

China is making its neighbors nervous these days. Chinese fighter jets are screaming into Taiwan's airspace. Hundreds of armed Chinese "fishing boats" are plying the disputed waters of the South China Sea. And Beijing is slashing imports from some trading partners because of disputes over political issues.

To push back against this increasingly aggressive behavior, regional powers Japan, India, and Australia, together with the US, are boosting cooperation via a 17-year-old grouping called the Quadrilateral Security Dialogue, or simply "The Quad." But how effectively can these four countries really work together to counter China? Eurasia Group's Peter Mumford discusses the Quad's future.

Want to tackle climate change? If so you'll have to reach out to China, which is currently responsible for over a quarter of global carbon dioxide emissions. Beijing will certainly take your call, as climate is a huge priority for President Xi Jinping.

Xi has promised that China will go "net zero" — meaning its carbon emissions will be offset by equal amounts of either natural or tech-driven carbon capture — by 2060. Is a decade later than most of the top 10 polluting countries fast enough for the rest of the world? It is for the Chinese, who want to help but have their own ideas about how.

When will it be safe for the world's children to be vaccinated against COVID-19? The World Health Organization's chief scientist, Dr. Soumya Swaminathan, says that vaccines are being tested in children down to the age of six or even lower, and promises that data on children will be shared as soon as it's available. She also notes that there are not enough studies on transmission in schools, and the WHO has advised governments to prioritize schools "over other things like shopping malls or cinema halls or pubs." Dr. Swaminathan spoke with Ian Bremmer in an interview on GZERO World, airing on US public television stations starting April 9. Check local listings.

Over the past half century, climate change has had an immense impact on the farmers who produce the food we eat. A new study by Cornell University shows that global warming has knocked 21 percent off of global agriculture productivity growth since 1965, equivalent to seven years of normal growth if humans had not polluted the planet. But not all countries have been affected in the same say. Farmers in warmer parts of the world have been hit hard as conditions grow more arid, but sub-polar regions in Canada or Siberia are now actually better for agriculture because they are not as cold as they used to be. Here we take a look at how climate has affected farming productivity growth around the world.

On Tuesday, a major US intelligence report said the top threat to America right now is China. A day later, John Kerry, the Biden administration's "climate czar," got on a plane to... China.

Such is the drama of ties between the world's two largest economies these days.
