What happened

As summer temperatures soar across the United States and Europe, cities are being forced to confront the difficult reality that they’re getting dangerously hot.

Why it matters

Record-breaking heat waves strain power grids, send people to cooling shelters and can make the top floors of some apartment buildings unlivable.

Common ground

One way to help cool buildings is to install green roofs – living rooftops covered by plants that can transform heat-absorbing rooftops into cooling solutions.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
