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.

There is no last word in research, and that includes climate research. It's never the truth that scientists offer, but only our best possible approximation of reality. But that often gets forgotten in the way the public perceives and describes our work.

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.

We climate researchers can only offer possible scenarios. In other words, things could end up being completely different. But there are undoubtedly parts of the world that will benefit on balance from climate change. Those areas tend to be in the north, where it has been cold and uncomfortable in the past. But it's considered practically heretical to even raise such issues.

Unfortunately 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.

We can no longer completely avoid anthropogenic climate change. At best, limiting the temperature rise to two degrees is just about possible, according to optimistic estimates. That's why we should spend more time talking about adjusting to the inevitable and not about reducing CO2 emissions. We have to take away people's fear of climate change.

The 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.
