Anthropogenic climate change poses a serious threat to coral reefs around the world. The impacts of global warming can be isolated by studying long-lived corals growing on remote, uninhabited islands of the central tropical Pacific, where human impact is nonexistent. By analyzing the chemistry of large coral skeletons collected from reefs in this area, they can reconstruct the monthly history of temperature and rainfall patterns for the last 50 to 100 years.

Multi-colored anemones, lavender bryozoans, and other organisms cover rocks in a kelp forest near Vancouver Island in western Canada. Strong currents around the island carry nutrients into the Queen Charlotte Strait, supporting an abundance of marine wildlife there.

There’s a jungle inside Vietnam’s mammoth cavern. A skyscraper could fit too. And the end is out of sight.
