They are gray and rectangular, and if you laid all 2 billion of them together they would cover an area roughly the size Connecticut, about 5,500 square miles. Parking lots have a monotonous ubiquity in US life, but a growing band of cities and states are now refusing to force more on people, arguing that they harm communities and inflame the climate crisis.

For many years, local governments have required the construction of parking lots as part of any development. These measures, along with expansive highways that cut through largely minority neighborhoods and endless suburban sprawl, have cemented cars as the default transportation option for most Americans.

Starting in January, though, California will become the first US state to enact a ban on parking minimums, halting their use in areas with public transport in a

The European Union is sick of talking about climate change; now it wants to act. The world’s second-largest economy is attempting to become the first climate neutral continent by 2050 while slashing its emissions 55 percent by 2030 compared to 1990 levels. To reach these milestones, the bloc’s executive arm, the European Commission, unveiled the Green Deal in 2019—a proposal to radically redesign Europe’s energy, food, and transport systems. “This is Europe’s man on the moon moment,” said European Commission president Ursula von der Leyen. 

Crucially, the Green Deal is still a proposal, not a concrete plan. Large parts have yet to be passed into law, and some member states need convincing that the associated costs will be worth it. The Commission has said the plan will require around €1 trillion ($1.05 trillion) in sustainable investments. Even targets already agreed upon aren’t binding. One EU official, Thierry Breton, suggested that

But attribution science can do a lot more than tell us how climate change influences the weather. Otto wants to use her attribution reports to hold polluters to account for extreme weather events. “We have started to do a lot of work with lawyers, to basically bridge this knowledge gap between what we can say scientifically and what has so far been used in terms of evidence,” she says. With legal cases underway in Germany and Brazil, attribution science is moving into the courtroom.

OTTO COFOUNDED World Weather Attribution in 2014 with the oceanographer Heidi Cullen and climatologist Geert Jan van Oldenborgh. At first, Otto—who has degrees in physics and philosophy—thought that the main role of weather attribution was to untangle the complexity of weather systems to quantify how much climate change was influencing extreme weather. Other scientists had established how to use climate models to attribute weather events to
