There seems to be increasing consensus that global temperatures have leveled off or fallen slightly over the past few years. Meteorologists are blaming the change on the cooling of the Equatorial Pacific waters (La Nina). Those same meteorologists still suggest that as those waters go into a warmer cycle, global temperatures will once again begin to rise. Greenhouse gases have generally been seen as the culprit for steadily rising temperatures during the past 100 years and those gases continue to slowly increase. However, some meteorologists are now suggesting that ocean water cycles and even solar cycles may have as much or more impact on the World's temperatures and precipitation. Over the next two decades less intense solar cycles and a tendency for more La Nina episodes (cold water conditions) suggest that global temperatures may actually fall slightly unless greenhouse gases increase significantly.
