Activists, politicians and economists are forever arguing over the best way to address climate change: carbon tax or Green New Deal; both or neither, or a mixture of elements from each. A new International Monetary Fund (IMF) report released Thursday cuts through that noise: any aggressive policy, it says, is better than nothing at all.

“We definitely want action to be taken,” says Paolo Mauro, deputy director of fiscal affairs at the IMF, who oversaw the report. “We’re not religious about any particular type of measure.”

The new report comes as a range of different climate policies are under consideration in the U.S. Proposals for a Green New Deal — an ambitious spending program aimed at eliminating emissions and funding social programs — have garnered the most attention in recent months. All the major Democratic presidential candidates have embraced some form of a Green New Deal, and activists have pushed aggressively for such a program. But proposals for a carbon tax have also bee..

(LONDON) — Protesters in New York City brought traffic to a standstill in the city’s busiest hub and an activist in London climbed atop a plane as climate change demonstrators entered the fourth day of rallies around the world.

Protesters transported a green boat on a trailer into Times Square and then sat down and refused police orders to move.

The boat bore the logo of the activist group Extinction Rebellion. It also had the words “Act Now” written on it and a string of brightly colored flags.

Some of the demonstrators carried signs in the shape of orange rescue lifebuoys, with the words, “Save our Future.”

The New York Police Department made dozens of civil disobedience arrests and removed the vessel some time later, which led to re-opened area streets and brought the traffic back to normal.

In London, a climate change activist scaled a British Airways plane at London City Airport. Extinction Rebellion identified the activist as a former Paralympic cyclist. A video streamed by ..

Ibrahim al-Asiri, a senior al-Qaeda bomb maker and terrorist coordinator, was killed two years ago in a United States operation in Yemen, the White House announced on Thursday.

Al-Asiri had been in hiding in Yemen for years and was the repeated target of U.S. drone strikes. The U.S. mistakenly believed they had killed him in a 2011 strike. They later targeted a man they believed was al-Asiri in a May 2012 strike, but he turned out to be another al-Qaeda leader.

As TIME wrote in 2013, the Obama administration believed al-Asiri was “the most dangerous terrorist in the world.” He was connected to the failed “underwear bomb” aboard a U.S.-bound flight on Christmas Day 2009, and allegedly built bombs that nearly detonated within two Chicago-bound international cargo planes in 2010. Al-Asiri also allegedly planned to blow up a U.S. airliner in 2012 around the anniversary of al-Qaeda leader Osama bin Laden’s death, but was stopped when the member chosen for the suicide mission turned out to..
