In the U.S., notable locations with radars (green circles) include Portland, San Francisco, Los Angeles, San Diego, Denver, Dallas, Chicago, and Miami. Almost every state has at least one radar, except for Rhode Island, Connecticut, and New Hampshire.

A world map shows water resources vulnerability.

Measure of projected water stress in the year 2020; water stress is the ratio of total annual water withdrawals to total available annual renewable supply.

Water Resources Vulnerability

Areas shaded in light yellow represent regions with arid and low water use, predominantly found in parts of Australia (central regions), Egypt, Saudi Arabia, Libya, Mauritania, and Yemen. Regions with low vulnerability, less than 10 percent, are shown in light orange and are primarily located in most parts of Africa, South America, Canada, Russia, most of Asia. Areas with low-medium vulnerability, ranging from 10 to 20 percent, are depicted in orange and are scattered throughout some parts of Japan and U S A, some parts of Asia and Europe. Medium-high vulnerability areas, between 20 to 40 percent, are shown in light red and are mainly found in South Africa, China, and many more. High vulnerability regions, ranging from 40 to 80 percent, are shaded in red and are located in parts of U S A, Europe, and Asia. Areas with extremely high vulnerability, over 80 percent, are shown in dark red and include most of U S A and Asia. Some areas such as Greenland and South Pole are marked with a gray shade, indicating no data available for those regions.

Mean sea-surface temperatures shown using patterns of latitudinal bands extend roughly east to west. The coldest temperatures are shown in the northern latitudes. Temperatures warm as latitudes near the equator.

Average sea-surface temperatures between 1990 and 2020

Mean Sea-Surface Temperature

Sea-surface temperatures create latitudinal bands extending east to west, influenced by ocean currents and continents. In the tropics, temperatures range from 24.0 to 32.0 degrees Celsius; in the midlatitudes, from 8.0 to 23.9 degrees Celsius; and in higher latitudes and polar regions, from negative 2.0 to 7.9 degrees Celsius. Significant deviations occur along the Atlantic coast of western Europe, where temperatures are warmer than the east coast of North America at the same latitude, and along the Pacific coast of Canada, the Atlantic coasts of Canada and the northeastern United States, and the western coasts of South America and southern Africa, where waters are cooler than expected. The hottest ocean areas are between Indonesia and Australia (30.0 to 32.0 degrees Celsius), followed by tropical parts of the western Pacific and Indian oceans, and small areas along the coasts of West Africa and Central America (28.0 to 29.9 degrees Celsius).
