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:
“i sing of Olaf glad and big
whose warmest heart recoiled at war:
a conscientious object-or”
—E.E. (Edward Estlin)
“While most of today’s jobs do not require great intelligence, they do require greater frustration tolerance, personal discipline, organization, management, and interpersonal skills than were required two decades and more ago. These are precisely the skills that many of the young people who are staying in school today, as opposed to two decades ago, lack.”
—James P. Comer (20th century)
