Now that we’ve all been warned we should prepare for global warming and that it’s imperative to cut down on greenhouse emissions, and now that even the opponents of such theories have started to agree with them, scientists came again to break the myth and say it’s not human activities, but nature’s own actions that provoke climate changes.

According to a report published by the Heartland Institute and written by S. Fred Singer, professor emeritus of environmental sciences at the University of Virginia, and project leader for the Nongovernmental International Panel on Climate Change (NIPCC), we are far from being able to sustain theories that at the cause of global warming lie anthropogenic causes, rather than natural ones.

“Our concern about the environment, going back some 40 years, has taught us important lessons,” the report says. “It is one thing to impose drastic measures and harsh economic penalties when an environmental problem is clear-cut and severe. It is foolish to do so when the problem is largely hypothetical and not substantiated by observations.”

In the three day-conference sponsored by the Heartland Institute, over 500 people from all corners of the world attended to talks on global warming and its probable causes, all of them advocates of natural, rather than human ones.

One thing scientists, economists and policy advocates at the conference complained about is the lack of tolerance from various journals and newspapers on other theories than what seems to be a global issue at the moment – how to cut down on greenhouse emissions.

“The claim that man is the primary cause of the recent warming is not supported by science,” the report says. The study highlights the fact that there could be many causes for climate change on a global scale, but one that can’t be ignored and with a major influence is most certainly solar variability. “There are also natural oscillations of internal origin, especially on a regional scale, that do not appear to be connected to human causes either.”

As an overall conclusion, the report finds that their findings, “if sustained, point to natural causes and a moderate warming trend with beneficial effects for humanity and wildlife.” This could perhaps make us look at things from a different perspective. For now, there is only one ‘conclusion to all the conclusions’: the debates will go on.
