Global temperatures will drop slightly this year as a result of the cooling effect of the La Nina current in the Pacific, UN meteorologists have said.This underscores the point that the science of global warming is not as well understood (or agreed upon) as many would have us believe. The issue has been so politicized, it makes it more difficult for good scientific and economic research to be done in the area. Climatologists are needed to research what is going on and why. Economists are needed to explain the potential effects on the economy, natural resources, and the effectiveness of policies on behavior.
The World Meteorological Organization's secretary-general, Michel Jarraud, told the BBC it was likely that La Nina would continue into the summer.
This would mean global temperatures have not risen since 1998, prompting some to question climate change theory.
Unfortunately, most of the people who serve as mouthpieces for global warming are not trained in either discipline. That's why I have strong concerns about politicians and church pastors who take strong stands on global warming. They seem to be motivated far more by trying to show good intentions and responding to emotion rather than weighing scientific evidence. Cooler heads are needed to win the day.
