Governments may say they’re doing all they can to halt the climate crisis. Don’t fall for it – then we might still have time to turn things around
Maybe it is the name that is the problem. Climate change. It doesn’t sound that bad. The word “change” resonates quite pleasantly in our restless world. No matter how fortunate we are, there is always room for the appealing possibility of improvement. Then there is the “climate” part. Again, it does not sound so bad. If you live in many of the high-emitting nations of the global north, the idea of a “changing climate” could well be interpreted as the very opposite of scary and dangerous. A changing world. A warming planet. What’s not to like?
Perhaps that is partly why so many people still think of climate change as a slow, linear and even rather harmless process. But the climate is not just changing. It is destabilising. It is breaking down. The delicately balanced natural patterns and cycles that are a vital part of the systems that sustain life on Earth are being disrupted, and the consequences could be catastrophic. Because there are negative tipping points, points of no return. And we do not know exactly when we might cross them. What we do know, however, is that they are getting awfully close, even the really big ones. Transformation often starts slowly, but then it begins to accelerate.
The German oceanographer and climatologist Stefan Rahmstorf writes: “We have enough ice on Earth to raise sea levels by 65 metres – about the height of a 20-storey building – and, at the end of the last ice age, sea levels rose by 120 metres as a result of about 5C of warming.” Taken together, these figures give us a perspective on the powers we are dealing with. Sea-level rise will not remain a question of centimetres for very long.
The Greenland ice sheet is melting, as are the “doomsday glaciers” of west Antarctica. Recent reports have stated that the tipping points for these two events have already been passed. Other reports say they are imminent. That means we might already have inflicted so much built-in warming that the melting process can no longer be stopped, or that we are very close to that point. Either way, we must do everything in our power to stop the process because, once that invisible line has been crossed, there might be no going back. We can slow it down, but once the snowball has been set in motion it will just keep going…
“This is the new normal” is a phrase we often hear when the rapid changes in our daily weather patterns – wildfires, hurricanes, heatwaves, floods, storms, droughts and so on – are being discussed. These weather events aren’t just increasing in frequency, they are becoming more and more extreme. The weather seems to be on steroids, and natural disasters increasingly appear less and less natural. But this is not the “new normal”. What we are seeing now is only the very beginning of a changing climate, caused by human emissions of greenhouse gases. Until now, Earth’s natural systems have been acting as a shock absorber, smoothing out the dramatic transformations that are taking place. But the planetary resilience that has been so vital to us will not last for ever, and the evidence seems to suggest more and more clearly that we are entering a new era of more dramatic change.
Climate change has become a crisis sooner than expected. So many of the researchers I’ve spoken to have said that they were shocked to witness how quickly it is escalating.
