Another Expert Says Man-made Global warming a Myth

Most of y’all know my view on global warming. I don’t think we have enough info to say that MAN-MADE global warming is a given fact, and I believe that most of it is just hype. There are too many experts out there who disagree with Gore’s hysterical rantings, and this article spotlights an interview with one. I just want us to react to FACTS not HYPE!

THE NEW AMERICAN: Flip on any channel, open any newspaper or magazine, and it’s clear we are being bombarded with the message that the Earth is warming. Is there any merit to this claim?

Dr. Arthur Robinson: Yes, but the temperature is only going up 0.5° C per century. Moreover, this increase is not being caused by human activity.

TNA: Those who blame mankind for causing global warming would respond to that point by saying that the Earth is the warmest it’s been in 400 years, and that’s significant.

Dr. Robinson: They’re right, but they only show you the data from the last 400 years. If the data for a longer time interval is considered, temperatures today are seen to be not especially warm. The current temperature is about average for the past 3,000 years. It was much warmer during the Medieval Climate Optimum 1,000 years ago (see Figure 1). The climate, as we know from historical records, was just fine during that warm period. In fact, it was a little better. So, yes, it is the warmest in 400 years.

Moreover, the temperature, which is going up very slowly, is correlated with the sun’s activity, not hydrocarbon use.

TNA: Those same people would say that science has spoken, that CO2 is the cause. What do you say?

Dr. Robinson: Gore, et al., tell us that CO2 is a pollutant, and that humans have caused this terrible problem. But actually the atmosphere contains lots of carbon dioxide. Carbon dioxide, water, and oxygen are required for life. Without these substances in the atmosphere, life would not be possible. All of the carbon in our bodies originates as atmospheric carbon dioxide. Plus, we’re only adding moderately and temporarily to CO2 levels. Carbon dioxide moves through the atmosphere on its way to the oceans and biosphere. Human use has caused a transient increase during the past century – from about 0.03 percent to 0.04 percent of atmospheric molecules. Man is producing about 8 gigatons per year, and yet there are 40,000 gigatons in the biosphere and oceans.

TNA: Which come from?

Dr. Robinson: Which are just there – created as part of nature. Between 1880 and 1890, the level of CO2 in the atmosphere was about 295 ppm [parts per million]. For comparison, this office right now is rising toward 1,000 ppm because we’re all exhaling carbon dioxide.

The human-caused increase in the atmosphere is not permanent, but temporary. This increase is only being maintained by our production and, as soon as we stop producing at some later time when our technology advances, it will go back to its naturally controlled level.

When we use hydrocarbons, the resulting carbon dioxide goes through the atmosphere on its way to the oceans and biosphere, so there is a rise in the atmosphere. Carbon dioxide has a very short half-time of about seven years in the atmosphere. However, while it is in higher concentration, it is wonderful for us because it makes our plants grow faster, which markedly increases the amounts and diversity of plant and animal life.
