Officials fear the already-giant fire in Alberta, Canada could double in size by the time Sunday rolls around to the Western Hemisphere, pushed by hotter than average winds and feeding on dry bush.  More than 25,000 of the 88,000 people who were routed from Fort McMurray must be relocated as the flames threaten to cut off the northern shale oil camps where they sought refuge.  Thousands were already taken south to Calgary and Edmonton by caravan and airlift, getting a glimpse of the epic destruction of Fort McMurray.  The Canadian Red Cross has raised US$44 million for those affected, and Prime Minister Justin Trudeau's government has pledged to match individual donations made until the end of May - "without a cap."

Tens of thousands of Poles marched through Warsaw and other cities against the conservative government and in support of continued European Union membership.  Critics say the ruling and ironically-named Law and Justice party and its "reforms" of judicial, surveillance, and media laws are undemocratic and in violation of EU laws and European values.  Kamila Gasiuk-Pihowicz of the opposition told more than 240,000 people that the ruling party's anti-Europe stance risk pushing the country back under Moscow's influence:  "Only two trains leave from the historic station at which Poland is standing. One is the European Express. The other is the Trans-Siberian Railway."

Workers sick of the layoffs under conservative President Mauricio Macri have virtually shut down Argentina's southern city of Comodoro Rivadavia in the major oil-producing region.  Some 50,000 Oil workers, teachers, truckers, and more workers are protesting Macri's free market policies that, in just a few months, have resulted in a steady stream of layoffs and company closures.  Inflation has skyrocketed to 36 percent.

Rising sea levels caused by global warming have claimed at least five reef islands in the Solomon Islands, damaged six more, and forced the relocation of several communities.  A study published in Environmental Research Letters is the first to confirm evidence found across the Pacific of increasing damage from this aspect of climate change.

Mexico has relocated the drug lord Joaquin "El Chapo" Guzman to a new prison near the Texas border.  This could indicate two things:  First, that Mexican officials suspect that El Chapo, who twice before pulled off brazen escapes,  might be planning another prison break;  Or second, that Mexico may be ready to extradite him to the US, which wants to try him on drug running charges. 

An Ivy League economist was almost kicked off of a commercial airline flight in the United States, after a passenger glanced at the sophisticated  equation he was working on and mistook it for a terrorist message.  Apparently those Arabic numerals were a little too much like Arabic for the unnamed passenger, who insisted that the flight crew and airport security in Philadelphia racially profile the man with his dark, curly hair, olive skin, and an exotic foreign accent.  After men in black suits came and questioned the mysterious passenger, they determined  that Guido Menzio wasn't working for Al-Qaeda as he was for Al-Gebra:  He's a professor of economics at the University of Pennsylvania, and his seatmate was an idiot.

UK Labour's Sadiq Kahn has been sworn in as mayor of London.  Referring to his childhood in a council estate as the scion of Pakistani imigrants, he said: "I'm only here today because of the opportunities and helping hand that our city gave to me and my family.  He also referred to the divisive, dog-whistle campaign waged by his Tory rival that sought to portray Mr. Kahn as sympathetic to Islamic extremists, he noted that the "decency of Londoners, the decency of British people will always cut through."
