What remains of the global, open internet came under attack this month.

The U.S.-China dispute just took a dangerous turn. Late last week, the U.S. government issued three separate measures – two executive orders imposing sanctions on social-media networks WeChat and TikTok, and another to set up a “clean network” program – that, come mid-September, would prohibit any U.S. citizen or company from conducting business with those apps’ Chinese parent companies, Tencent and ByteDance respectively.

The only surprise about Jair Bolsonaro’s diagnosis for COVID-19 was that it took him so long to test positive.

“I can’t breathe.” The final words gasped by George Floyd are now a global meme. They were recorded on the mobile phone of a bystander while Mr. Floyd was being suffocated to death by a police officer in Minneapolis.

The coronavirus pandemic is exposing the quality of governments around the world. Many national leaders have failed the test—in contrast to the leaders of regions and cities

Violence has always been one of humanity’s most serious global challenges. This is because for most of history, we were natural born killers. Hundreds of millions of men, women and children have been killed or maimed by armed conflict, crime, extremism and sexual and gender-based violence.

The world is waking-up to the climate emergency. But our prolonged slumber is going to cost us dearly. The latest scientific findings indicate that our planet is approaching multiple “tipping points” that could cause irreversible and catastrophic changes in temperature, ecosystems and biodiversity.

Make no mistake: the world is in the early stages of a techno-war against city governments and urban infrastructure. And while some cities have bolstered their capabilities to patch their vulnerabilities, they are entirely unprepared for the scale of cyberthreats that are coming.

Brazil is the world’s murder capital. No other country even comes close. That is why it was big news when the country’s minister of justice recently announced that homicide rates fell by over 20 percent in 2019 compared to the same period last year.

The fate of the Amazon is intertwined with the fate of the world. If 20-25 percent of its tree cover is cut down, scientists estimate, the basin’s capacity to absorb carbon dioxide would be severely compromised, taking out of operation one of the world’s largest carbon sinks.
