Dr. Hugh Ross, founder/president of the ministry Reasons to Believe, based in the US, is an astronomer-turned-apologist specialising in Bible-science issues. Dr. Ross spoke to our Christian Today correspondent last week about global warming and what he believes are overlooked factors that cause the increase warming of the earth, including: the earth's orbit, domestication of cows, cultivation of rice, and deforestation.
How do you believe Christians should feel towards environmental issues?Ross: God put the human race in charge of managing the resources of the entire planet for the benefit of all life. Therefore we of all people on this planet should be concerned about environmental issues and doing what we can to enhance the beauty and productivity of the natural realm.
Why is everyone focused on fossil fuel burnings as the main factor contributing to global warming?
Ross: Well, that certainly has gotten the public attention. A lot of it has to do with the fact that we simply are not aware of other human activities that make as big or bigger contributions to global warming. The fact is the planet is warming right now and it is easier to blame it on some human activity rather than saying we should better understand the whole problem and recognise there are natural conditions that are impacting this too.
Another factor is that we human beings have gotten too use to the fact that we have an exceptionally benign global climate right now. We don't appreciate how finely tuned the characteristic of the whole galaxy, solar system, and earth must be to bring about those conditions. If you look at the past record of the earth, we have to realise that this is very temporary.
I had pointed out earlier the earth's history over the past several million years is that for every 100,000 years, we go through a dramatic climatic cycle where we get 90,000 years of ice age and 10,000 years of a warm period. I think people today just have the expectation that we deserve a perfectly benign climate forever.
Is what you're saying radical?
Ross: I don't think that it is a radical idea. Our main point is that this is a very complicated issue with many contributions, both natural and human, and we can easily make a mistake by putting too much emphasis on one factor and ignoring other factors. The potential in many environmental issues is that if you undertake corrective action without appropriate understanding of the problem then you wind up doing more harm than good.
The Evangelical Climate Initiative's statement cites the Intergovernmental Panel of Climate Change as saying most of the warming is due to human activities, in particular, the burning of fossil fuels. This is contrary to what you are saying. What is your response?
Ross: That is probably the most significant in terms of new human activities, but the fact is that we human beings have been altering the climate through other factors literally for thousands of years.
I mentioned the domestication of cows and the way we harvest rice these days by irrigating fields. Those two activities alone have nearly doubled the amount of methane in the atmosphere and methane is a far more powerful greenhouse gas than carbon dioxide.
The other thing we have done is cut down a lot forest to make pastures and agricultural land. Forests are a big factor in absorbing carbon dioxide in the atmosphere.
