Harvard’s David Keith explains why it’s time to move forward with outdoor experiments and broader research programs.
We’ve built our cities and flood protections with assumptions based on the climate of the past.
The climate researchers intend to launch a high-altitude balloon that would spray a small quantity of reflective particles into the stratosphere.
As climate change accelerates, a handful of scientists are eager to move ahead with experiments testing ways to counteract warming artificially. Their reasoning: we just might get desperate enough to use this technology one day.
By reworking the basic metabolism of crops, plant scientists hope to forestall devastating food shortages.
