Warmest Decades
Numerous cycles have been found to influence annual global mean temperatures. The tropical El Niño-La Niña cycle and the Pacific Decadal Oscillation are the most well-known of these cycles. An examination of the average global temperature changes by decades reveals continuing climate change. Following chart is from NASA data of combined land-surface air and sea-surface water temperature anomalies.

Famous quotes containing the words warmest and/or decades:
“O Scotia! my dear, my native soil!
For whom my warmest wish to Heaven is sent,”
—Robert Burns (1759–1796)
“We all run on two clocks. One is the outside clock, which ticks away our decades and brings us ceaselessly to the dry season. The other is the inside clock, where you are your own timekeeper and determine your own chronology, your own internal weather and your own rate of living. Sometimes the inner clock runs itself out long before the outer one, and you see a dead man going through the motions of living.”
—Max Lerner (b. 1902)
