Carbon capture and storage, or CCS, has been touted as a way to reduce atmospheric CO2. But how realistic is it to build CCS facilities on a scale large enough to combat climate change?

In keeping the hands of the Doomsday Clock at three minutes to midnight, the members of the Bulletin of the Atomic Scientists Science and Security Board mean to make a clear statement: The world situation remains highly threatening to humanity, and decisive action to reduce the danger posed by nuclear weapons and climate change is urgently required.

Amid a changing climate, more mass evacuations will be necessary. Let’s try to learn from past mistakes.

Something more than journalism, something that approaches … poetry.

We often hear about Germany’s audacious ‘energy turn-around,’ or Energiewende, from fossil fuels to renewables. But how has it really worked in practice, from the viewpoint of someone who has worked for more than two decades for both Germany’s utilities and large, energy-intensive industries? What lessons can the United States take from observing the German experience?

It is ironic that while the scientific community has long tried to raise warning signals and induce action to address human-induced climate change, an encyclical from the pope on this subject is being taken by many as an ultimate call to action on this urgent issue.

The energy used to recover and recycle the minerals found in this "e-waste" produces as little as one-tenth the carbon emissions needed to mine for virgin metals. But there's a few hitches to sort out first.
