Sea ice still too thick for Arctic shipping route

Despite climate change, sea ice will continue to make the Northwest Passage too treacherous to be a regular Arctic shipping route for decades, says study.

NASA's New Horizons captured this high-resolution enhanced color view of Charon just before the spacecraft's closest approach on July 14, 2015. The image combines blue, red and infrared images taken by the spacecraft’s Ralph/Multispectral Visual Imaging Camera (MVIC); the colors are processed to best highlight the variation of surface properties across Charon. Charon’s color palette is not as diverse as Pluto’s; most striking is the reddish north (top) polar region, informally named Mordor Macula. Charon is 754 miles (1,214 kilometers) across; this image resolves details as small as 1.8 miles (2.9 kilometers). Image credit: NASA/JHUAPL/SwRI

High ‘supermoon tides’ strike coasts

Sunday’s supermoon, combined with an 18.6-year lunar cycle, caused high tides on both sides of the Atlantic this week. There were many flood warnings and alerts in effect in the UK on Tuesday night. In eastern North America, Tropical Storm Joaquin might combine with high tides to cause flooding.
