"As they review the bizarre and unpredictable weather pattern of the past several years, a growing number of scientists are beginning to suspect that many seemingly contradictory meteorological fluctuations are actually part of a global climatic upheaval. However widely the weather varies from place to place and time to time, when meteorologists take an average of temperatures around the globe they find that the atmosphere has been growing gradually cooler for the past three decades.

Which makes in ancient history. Seriously, the climate sciences have advanced a lot since then, and we now know the cause of the brief cooling period the article is talking about: particulate pollution. After catalytic converters and other pollution controls became mandatory, particulate pollution decreased, and the warming trend resumed.
