There’s a funny piece over on Boundless Line about the dangers of “dihydrogen monoxide”. Unfortunately it uses it as a way of taking a side-swipe at us humans causing global warming. For some reason, the Religious Right in America seems particularly hostile to the idea – which given its political influence, and the overwhelming evidence for anthropogenic climate change, is rather worrying. To repeat what I said in the comments… if there is some doubt about whether or not climate change is caused by our activities, shouldn’t we, as responsible stewards of God’s creation, err on the side of caution in responding to climate change? But “erring on the side of caution” isn’t really necessary – the evidence is overwhelming. Climate change is a reality – fact. What’s more, the vast majority of scientists are agreed that it is caused by human activity. The Intergovernmental Panel on Climate Change (IPCC), internationally recognised as an authority on the subject, puts the probability of climate change being anthropogenic at 90% or higher. The current US Government calls the science “beyond doubt”. No-one denies there are natural factors by which the Earth’s climate varies a bit, but the level of climate change goes above and beyond that which can be explained by such processes. Thinking critically about the evidence we are presented is very important, but to deny anthropogenic climate change is to fly in the face of the scientific evidence and the consensus among the vast majority of climate change scientists.
