— LEWISBURG — An internationally known meteorologist challenged common perceptions about the causes of global warming during Monday night’s meeting of the Susquehanna Valley Conservatives.
“Is the temperature on Earth warmer than it was 100 years ago?” asked Joe Lundberg, of State College-based AccuWeather. “Sure it is. Are C02 levels rising? Sure they are. Are oceans rising a little bit? Absolutely they are. But is everything caused by C02? Are all the problems we are seeing caused solely by the burning of manmade fossil fuels? That’s where the debate still needs to be talked about because I don’t think all the facts are in on that.”
Lundberg enthralled an audience of 90 people with facts about the “wonder and power” of weather.
Don’t believe all you hear about climate change, Lundberg said. Referring to several meteorological charts that denoted weather patterns over the past few centuries, he contended that a lot of the change in weather is cyclical.
“You have 30-year periods when the Earth is statistically colder,” Lundberg said, and then you’ll have a 15- to 20-year period when the ocean is warmer, the air temperature rises a few degrees. This is followed by another period of cold weather. “And so on ...”
Lundberg admitted that we are now in a period of warming temperatures.
“But what is the cause of all this?” he asked. Shrugging, he answered his own question: “I don’t know. I’m not a climate scientist. I’m just a weather forecaster. I’ll leave it up to you to take a look at the charts, the maps and the models that purport to predict what the temperature will be in 20 years.”
Lundberg pointed out that many predictive models and trend lines have been greatly exaggerated.
“Al Gore predicted that sea levels would rise by feet in the near future,” he said, “but statistics show that sea levels are rising by millimeters.”
The average temperatures over the past 15 years have stayed the same, he said.
“My point is, climate change is an easily debatable topic,” he said. “There are some things that both sides of the argument can agree on. But there are differences. And I want to point out to people to take a look at the facts. Don’t believe everything that you’re told because some of the things that we’ve been told over the past 15 to 20 years are not factual if you actually do the research and do a little bit of digging in the data.”
During a brief question-and-answer period, Lundberg was joined at the podium by fellow meteorologist Joe Bastardi, well known for his controversial stance on global warming.
Bastardi is a great believer in weather cycles and contends that C02 emissions are simply not a factor in shaping the weather — near or long term.
