Wind, solar, hydro, and geothermal seem mostly benign -- in part because they are still a small part of the energy equation. But when green gets big, it can be controversial.
A study finds that a fishing ban at a Mexican marine park – with critical help from local residents – has successfully restored the fish population. Whether it's enough to restore the industry is not clear.
Naomi Oreskes has become a leading voice in defense of the science underlying global warming and the scientists who are researching it.
The finding, in a new study by the Scripps Institution of Oceanography, could have implications for the food chain. The region of floating trash in the Pacific Ocean is double the size of Texas.
NASA is set to launch satellite Glory early Wednesday. It will measure incoming sunlight and atmospheric particles, both key to crafting better climate models.
Of the 18 species of penguins, 13 are considered either threatened or endangered. Some species on the brink of extinction.
Research shows that many areas of today's oceans have conditions that parallel those of 250 million years ago, when 95 percent of marine species quickly died out.
A new study suggests that a global rise in ocean temperatures has cut the number of phytoplankton, which are the bedrock of the food chain, by 40 percent since 1950. Other scientists link the rise in ocean temperatures to global warming.
