Caption

This image, taken by NASA's Terra satellite in March 2003, shows a much colder North America than Europe‑‑even at equal latitudes. White represents areas with more than 50 percent snow cover. NASA's Aqua satellite also measured sea-ice temperatures. Water between 0 and ‑15 degrees Celsius is in pink, while sea-ice between ‑15 and ‑28 degrees Celsius is in purple.
