This week, a study done by the United Nations University concluded that, as the planet warms, dengue fever could threaten much of Europe and South America where cold weather has historically kept mosquito populations low. The report said: “Changes in climate could result in increased exposure and pose a serious threat to areas that do not currently experience endemic dengue.”

If most sensible people look at such a report and shrug, the climate science community only has themselves to blame. I’m not one of those conspiracy theorists who believe scientists have been hijacked and bought by the left, but I do think we’ve been much too quick to accept the doomsday scenario envisioned by some. And I definitely believe that science has provided a hostile environment to researchers with conservative beliefs. And I know that the liberal media has played a role in twisting hard science for mass consumption, leading to panic where none need exist.

A Foggy Crystal Ball

The worst aspect of the green movement is their failure to realize that we’ve been down this road before. Whenever you get into predictions of the future, even the most radical scientist will admit that, well, there is room for doubt. If there wasn’t, we would regard scientists as modern-day prophets. They could tell us everything about the future like a prognosticator at a country fair. Unfortunately, when it comes to such predictions – especially as they pertain to climate change – scientists have about the same rate of success as those psychics.

In the early 1970s, the predominant climate change theory was that the world was headed into a period of global cooling. Some scientists went as far as to predict that we would experience a new ice age by the time we got to the millennium. We had to take action!

Well, we didn’t take action, and these predictions failed to materialize. Only a few years later, the scientific community abandoned their global cooling hypothesis in favor of global warming. Once again, without much hesitation, the mainstream media jumped on the scare wagon. That wagon continues to gain speed to this day, influencing American and global political policy, placing restrictions on private industry, and guaranteeing big ratings for whichever newscast can sound the alarms the loudest.

Science – when done right – is driven by skepticism. The entire scientific method is based on disproving claims. Yet when it comes to the issue of climate change, we are expected to take the opposite approach. We are supposed to greet each new prediction without question.

For years, we were told the scientific consensus on eggs was that eating more than three a week would lead to high cholesterol. Last year, though, a major study showed otherwise. It turned out that the cholesterol in eggs had no effect on the cholesterol levels in your body. That’s just one example of many where we’ve seen a complete turnaround on “settled science” just within our own lifetimes.

I’m not saying climate change is a hoax. I am saying that, if you’re skeptical, you have every right to be.
