    Glacial Geoengineering: The Key to Slowing Sea Level Rise?

    A new proposal suggests building underwater walls to protect glaciers from warm water. Here’s how it might work.

  • Pump Meltwater Back on Antarctica? Do You Have 850,000 Wind Turbines?

    Pump Meltwater Back on Antarctica? Do You Have 850,000 Wind Turbines?

    A new study that looked at the feasibility of lowering sea levels by pumping water onto icy Antarctica offers a warning about the costs today’s greenhouse gas emissions may be creating for future generations.

  • The Double-Edged Sword of Geoengineering

    The Double-Edged Sword of Geoengineering

    Shooting sulfur particles into the stratosphere to reflect the sun? Dumping iron into the ocean to boost the absorption of carbon dioxide? Could these far-fetched and dangerous-sounding schemes—geoengineering—help avert potentially catastrophic effects of climate change, or would they exacerbate conditions on our ever warming planet?

  • Climate News Roundup — Week of 6/14

    Bill Gates funds cloud-whitening effort to reduce global warming.  USA Today Bill Gates is funding research into whether or not it is effective and feasible to increase the albedo of atmospheric clouds by spray sea mist high into the atmosphere. The plan, spearheaded by Silicon Valley inventor Armand Neukermans, is a relatively benign method of…
