New electrochemical technology could de-acidify the oceans – and even remove carbon dioxide in the process

Global warming is making the oceans more acidic. Our work aims to design realistic systems to reduce this acidity, and remove carbon from the atmosphere in the process.

The world is not moving fast enough on climate change — social sciences can help explain why

Climate change is often seen as solely a technical problem. This is a misguided belief. Understanding how to build a better world begins, and ends, with understanding the societies which inhabit it.

Flood risk mapping is a public good, so why the public resistance in Canada? Lessons from Nova Scotia

Public concerns for real estate value, and a focus on the self, make flood risk maps unpopular. However, these concerns should not dissuade governments from providing resources we can all trust.
