A map shows the p H levels of acid rain in the U.S. States like Ohio and Pennsylvania have the lowest p H levels (4.50 to 4.59 p H, black). States like Arizona and Nevada show the highest p H levels (greater than or equals 5.30 p H, light yellow).

Average acidity of precipitation in the United States. Lower pH values represent greater acidity.

A world map shows global terrorist attacks. The highest concentration of attacks is in regions such as the Middle East, Northern Africa, and South Asia. Areas with fewer attacks (sparse points) include North America, South America, and Australia.

The deadliest acts of terrorism from 1970 to 2016. These violent acts were aimed at attaining a political, economic, religious, or social goal, and there is evidence of an intention to coerce, intimidate, or convey some other message to a larger audience (or audiences) than the immediate victims.

Sea-surface temperature anomalies during El Niño. The most intense warming (2 to 2.25 degrees Celsius, dark brown) occurs off the coast of South America. Cooler areas (negative 2.25 to negative 2 degrees Celsius, dark blue) are in the Arctic Ocean.

A composite of sea-surface temperature anomalies during El Niño from November to March during the following years: 1958, 1966, 1973, 1983, 1987, 1992, 1996, and 1998. When sea-surface temperatures in the tropical eastern Pacific rise well above normal, it is known as an El Niño event.
