Our series is over, but the challenges remain.

Geoengineering could be used to lower global temperatures and capture carbon. The possibilities are tremendous, but so too are the risks.

Traditional assumptions about how we will feed the world’s rapidly growing population are being upended by climate change.

Preparing for the inevitable impacts of climate change through “adaptation.”

We have the technology to produce power from clean, renewable sources. So why don’t we?

Human endeavors in nature haven’t always yielded such neat outcomes.

Our dependence on coal, oil and natural gas is causing us problems — and it needs to be addressed immediately.

A modest proposal to fight world hunger and global warming, enjoy a tasty meal — and gross out most of your friends.

To reduce carbon emissions and meet increasing demand for electricity, we must overhaul our energy system and embrace a major expansion of nuclear power.

President Obama wants to expand pre-K nationally. Here’s why it’s not necessarily a good idea.

It’s a vicious cycle: Our transportation systems emit greenhouse gases that contribute to climate change. And in turn, climate change poses a huge threat to our transportation systems. What can we do?

Expiration dates can be misleading. A much more reliable indicator of whether products have gone bad? Your nose.

Congressional action on climate change may be stalled, but the Pentagon is taking a leading role. Rear Adm. David Titley explains why melting glaciers and rising sea levels constitute a dire threat to national security.

Could the widespread use of energy efficient technologies stem the rising tide of climate change? Our experts weigh in.

For better or worse, wind power is changing our natural landscape. Not everyone is pleased. But Anita Diamant suspects most people will come around.

It’s too late to stop climate change in its tracks, but there are things we can do to reduce and eventually stabilize greenhouse gas emissions.

It’s one thing to try to reduce your own, personal carbon footprint. But what if you’re a giant multinational corporation? Three business leaders outline what their companies are doing.

Geoengineering could be used to lower global temperatures and capture carbon. The possibilities are tremendous, but so too are the risks.

Master chef Thomas Keller says he cares about cooking great food, not about worrying whether it’s local. But Kathy Gunst says in today’s world, that’s the wrong recipe.

Our dependence on coal, oil and natural gas is causing us problems — and it needs to be addressed immediately.

Could the widespread use of energy efficient technologies stem the rising tide of climate change? Our experts weigh in.

Science can help us understand the causes and effects of climate change. But what we do about it is an ethical question.

Traditional assumptions about how we will feed the world’s rapidly growing population are being upended by climate change.

For a real economic recovery to take off nationally, it must happen among the millions of small enterprises in our cities and towns.

Most of our so-called ‘natural’ disasters are at least partly man made: Sandy is just the most recent example. Architects, engineers, and designers are often ahead of the curve, but we’ve got miles to go to prepare for future ‘acts of God.’
