Because of the inherent time lag in the climate system, the greenhouse gases that have already been pumped into the atmosphere will undoubtedly lead to a certain increase in temperature in the coming decades.
Hans von StorchUnfortunately many scientists see themselves too much as priests whose job it is to preach moralistic sermons to people. This is another legacy of the 1968 generation, which I happen to belong to myself. In fact, it would be better if we just presented the facts and scenarios dispassionately - and then society can decide for itself what it wants to do to influence climate change.
Hans von StorchThe reasons are likely rooted in religion. Playing around with God's creation is simply not allowed. Incidentally, in the past it was precisely the deeply religious people who said: Of course we're playing with God's creation, in fact we're perfecting it. This sort of thinking is frowned upon today.
Hans von StorchUnfortunately, some scientists behave like preachers, delivering sermons to people. What this approach ignores is the fact that there are many threats in our world that must be weighed against one another. If I'm driving my car and find myself speeding toward an obstacle, I can't simple yank the wheel to the side without first checking to see if I'll instead be driving straight into a crowd of people. Climate researchers cannot and should not take this process of weighing different factors out of the hands of politics and society.
Hans von StorchThe fear of climatic catastrophes is an ancient one and not unlike our fear of strangers. In the past, people believed that the climate almost always changes for the worse, and only rarely for the better - God's punishment for sinful behavior.
Hans von StorchIf things continue as they have been, in five years, at the latest, we will need to acknowledge that something is fundamentally wrong with our climate models. A 20-year pause in global warming does not occur in a single modeled scenario. But even today, we are finding it very difficult to reconcile actual temperature trends with our expectations.
