A map shows the minimum sea ice extent and glacial loss (2010 to 2020), marked by blue circles. The largest glacial loss is in the Gulf of Alaska, 83.1 gigatons, and the smallest in Iceland, Antarctic, and Subantarctic, 3.5 gigatons.

Loss of glacial ice between 1961 and 2016 measured using satellite imagery and field observations.

Approximate Form and Extent of Outcrop of Carbonate Rocks

The outcrops of carbonate rocks are scattered across various regions. In North America, notable areas include the southeastern United States and parts of Mexico. The Caribbean also has some carbonate rock outcrops. In South America, small outcrops are present in Brazil. Africa has outcrops in northwestern and southern regions, including Morocco, Algeria, and South Africa. Europe shows significant outcrops in central and southern areas, particularly in countries like Spain, Italy, and Austria. Russia has some outcrops, while Asia has smaller areas of outcrops in countries like Myanmar, Vietnam, Sri Lanka, and Japan. In Australia, outcrops are found in the southern part of the country.
