THE END OF WAR

THE END OF WAR

Your Friday author has fielded many questions recently about the chaotic state of current global affairs and the rising risks of a serious global conflict. After all, things do look pretty grim: we have an escalating trade fight between the world’s two largest economies, far-right nationalists on the rise in Europe, a US president intent on unmaking the global norms of the past thirty years, a Middle East that remains deeply unstable, and a slow-moving crisis of climate change that is only just starting to be felt.


But let’s put this current moment in perspective. Sunday will mark the 100-year anniversary of the armistice that ended World War I, a conflagration sparked by a street corner murder in Sarajevo, today the capital of Bosnia and Herzegovina, that became a wildfire as formal alliances brought more and more nations into conflict. Some 70 million people were sent into military action. The war killed nine million soldiers and seven million civilians, and it triggered a number of genocides as empires fell and borders were redrawn.

My grandfather, a would-be journalist, served as an American officer in the trenches in France and he left behind battlefield photographs that he took himself. They are modest portraits of scorched earth, ruined cathedrals, and devastated lives that I’ll be looking through again this weekend.

When the war ended, the soldiers’ return triggered an influenza epidemic, the so-called Spanish Flu, that infected an estimated 500 million people across the world: from the large metropolises of Europe and the US, to remote South Pacific Islands, and even to the Arctic. More than 50 million people died. My grandmother’s 11-year-old brother was among those who perished. I have no doubt many Signal readers will have personal connections to these two human catastrophes.

So as we worry over events of the day and how they might shape the 21st century, spare a thought this Sunday for all those who lived and died through those turbulent years. It may put things in perspective.

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.
