Bioluminescence--defined by Merriam-Webster as "the emission of light from living organisms (such as fireflies, dinoflagellates, and bacteria) as the result of internal, typically oxidative chemical reactions"--is one of the wonders of nature that just about any of us can witness.

How are global and regional climate models linked, and what information do they provide?

American businesses on their own have the collective economic power to help the U.S. meet its Paris climate commitments without support from the administration.

The technology to capture carbon from the air has existed since the 1950s. Now it can be used to make cost-effective fuels.

Many current and former US military leaders call climate change a serious national security threat, but few of them mention the Defense Department's big carbon footprint.

Sun, air, and water - just as nature uses - can be harnessed to produce fuels and fertilizer at a site, removing more carbon from the environment.

Home cleaning supplies can contain toxic ingredients that pollute your home. What are the Options?

Solar and wind can't deliver power on demand. But overbuilding solar and wind, and simply dumping unneeded energy, would go a long way to smoothing out those bumps, study finds.

Studies suggest that taking a walk in the forest can improve you health.
