More grist for the global warming debate:
Second, what the climate alarmists and their advocates in the media have continued to ignore is the fact that the Little Ice Age, which resulted in harsh winters which froze New York Harbor and caused untold deaths, ended about 1850. So trying to prove man-made global warming by comparing the well-known fact that today’s temperatures are warmer than during the Little Ice Age is akin to comparing summer to winter to show a catastrophic temperature trend.
A good point. The Earth may indeed be warming, but that doesn’t mean pollution’s the cause. Of course, this comes from a Republican senator, thus easily dismissed.
This isn’t so easy to dismiss — a letter to the editor signed by 60 scientists. They state that science has not concluded that man-made pollutants caused any global warming:
The study of global climate change is, as you have said, an “emerging science,” one that is perhaps the most complex ever tackled. It may be many years yet before we properly understand the Earth’s climate system. Nevertheless, significant advances have been made since the protocol was created, many of which are taking us away from a concern about increasing greenhouse gases. If, back in the mid-1990s, we knew what we know today about climate, Kyoto would almost certainly not exist, because we would have concluded it was not necessary.
… When the public comes to understand that there is no “consensus” among climate scientists about the relative importance of the various causes of global climate change, the government will be in a far better position to develop plans that reflect reality and so benefit both the environment and the economy.
“Climate change is real” is a meaningless phrase used repeatedly by activists to convince the public that a climate catastrophe is looming and humanity is the cause. Neither of these fears is justified. Global climate changes all the time due to natural causes and the human impact still remains impossible to distinguish from this natural “noise.”
This sounds like legitimate scientific dissent. But so many of the articles I read about global warming pretend as though there is no debate at all. For instance, this Wall Street Journal article states simply: “Separate experiments were able to link human impact to most of the observed warming.”
Journalists must report this debate — not pretend the debate doesn’t exist.
