The sea is rising three times faster than we thought.

A lot of climate hawks spent late 2016 and early 2017 in reassessment or mourning. Meanwhile, Anthony Torres was busy channeling his fellow engaged millennials into direct action, including coordinated sit-ins at the offices of New York’s Chuck Schumer, the new Senate Minority Leader, and Sen. Tom Carper of Delaware. The message: Do not play ball with the polluter-in-chief.

The son of a Nicaraguan immigrant father and a working-class New Yorker mother, Torres grew up with sea-level rise on his Long Island doorstep, and he understands how poverty, climate, and other social challenges are all knitted together. He’s proven especially adept at rallying peers to his side, both in an official capacity at the Sierra Club (where he helped coordinate communications and direct actions that aided in a defeat of the Trans-Pacific Partnership) and in extracurricular work with groups like #AllOfUs, a progressive collective aimed at organizing young people around threatened communities.

His advice on connecting different constituencies: “Activists need to create a story that is accessible to people who are not necessarily in our movements but who are in need of a bold and inspiring vision,” Torres says. “To me, it’s telling a story of America that intersects with race, gender, and class” and turning what might seem like differences into “a weapon in our arsenal that creates an America that never has happened before — a country for all of us.”

What the heck were thousands of red Skittles doing strewn across a frozen Wisconsin road?

That’s according to a new study published in Proceedings of the National Academy of Sciences.

You’re probably used to hearing about how denser cities cut transportation emissions, thanks to reduced driving. This study looks at a different impact: how density affects greenhouse gas emissions from buildings.

The researchers projected emissions from buildings under different potential urban densities between now and 2050. They found that denser development patterns lead to lower emissions because people live and work in smaller units that consume less energy. Attached buildings are also more efficient for heating and cooling.

So the PNAS study finds that greater density has the potential to substantially reduce building emissions, more so than other efforts to improve energy efficiency like better weather-proofing.

Unfortunately, global trends are moving in the wrong direction. Cities around the world are growing, but at the same time, urban density is decreasing, as cars enable cities and their suburbs to sprawl outwards.

Governments can adopt policies to make their cities and towns denser, and they’ll need to — not just in the relatively sprawling cities of North America and Europe, but in the fast-growing cities of Asia and the rest of the developing world.
