Our Climate Crisis—and What We Can Do About It

Understanding the full economic picture is the first step to making the right choices. What is the true cost and impact of our options? Is there a viable strategy for converting to 100% renewables, increasing efficiency, and reaching zero emissions? How would this impact the world economy?

Three Basic Facts about the Climate

Today everyone knows (or certainly should know) that the Earth is warming, that humans are the cause, and that this warming is changing our planet’s climate in a way that threatens life as we now find it.

Tipping Points – The Riskiest Bet

When our planet’s average temperature increases steadily and gradually, the climate–the range of the weather over a period of time–gradually changes as well, until it suddenly jumps into a new condition. Scientists who study these abrupt changes refer to them as tipping points.

Sunlight and Darkness in China

China, the world's largest emitter of greenhouse gases, has promised to shrink emissions to zero by 2060. It is critical to anyone born in this century that China keeps this promise.

India: Stepping Back from the Precipice

In recent years India has defied calls to abandon its aggressive plans to burn more coal. But now economics and a crisis in health have set the nation on a new course.

The Downside of Being First

The US has by far the most extensive energy infrastructure. Upgrading it for renewable energy will be difficult and expensive but enormously beneficial.

Our Dark Materials

Powering the world using sustainable energy will require huge numbers of wind turbines, solar panels, and storage batteries. These will need many new sources of rare earth materials.

Why We Should Care About Concrete

Concrete is one of the world’s most polluting materials, yet new approaches are transforming its environmental footprint. Innovations in low-carbon and bio-based concrete are opening the door to a more sustainable built environment.
