Piece-by-piece approach to emissions policies can be effective

Discussions on curbing climate change tend to focus on comprehensive, emissions-focused measures: a global cap-and-trade scheme aimed at controlling carbon, or a tax on...

Geoengineering approaches to reduce climate change unlikely to succeed

Reducing the amount of sunlight reaching the planet’s surface by geoengineering may not undo climate change after all. Two German researchers used a simple energy...

How do we balance needs of energy, water, and climate?

In deciding how best to meet the world’s growing needs for energy, the answers depend crucially on how the question is framed. Looking for...
