Sea level is rising -- and at an accelerating rate -- largely in response to global warming. A 2013 fact sheet from the Union of Concerned Scientists.

Sea level is rising—and at an accelerating rate—especially along the U.S. East Coast and Gulf of Mexico.

The U.S. can dramatically expand renewable energy by utilizing existing technologies and making smart investments to improve the country's electricity system.

Many aging, water-intensive coal-fired power plants are vulnerable to energy-water collisions, which can have a significant impact on electricity production.

UCS's 2013 report, Grading Government Transparency, looks at policies governing scientists' communications through traditional and social media at 17 federal agencies.

The environmental impacts of geothermal energy vary depending on the technology used to generate electricity and the type of cooling system utilized.

Hydroelectric power includes both massive hydroelectric dams and small run-of-the-river plants, both of which have associated environmental impacts.

Hydrokinetic energy includes wave and tidal power and encompasses an array of energy technologies, many of which are still in the experimental stages or in the early stages of deployment.

The potential environmental impacts associated with solar power depend on the technology, which includes two broad categories: photovoltaic solar cells and concentrating solar thermal plants.

Wind power generates electricity without toxic pollution or global warming emissions, but it does have some environmental impacts that should be recognized and mitigated.
