Climate change can't be stopped, but we will adapt

Chris Berg in the Sydney Morning Herald: …The world is acting on climate change. But not acting to stop it - to adapt to it. In the 1920s, an average of 240 people out of every million died every year from extreme weather events: drought, flood, windstorm, landslide, earthquake, extreme temperatures and wildfire.

According to data from the International Disaster Database, last decade that figure dropped to just three per million. Actually, the numbers are even better than they first look. The 20th century saw a 99.9 per cent reduction in the risk of death from drought. And the risk of death from floods came down almost as much: 89 per cent. Floods and drought - two of the most commonly mentioned consequences of climate change. We're getting much better at managing and surviving them.

The causes of this remarkable decline in mortality are many. Better transport and communications help move food to where it's needed, quicker. Globalised trade gives producers an incentive to do so. Hardy modern agriculture can survive not just long-term climatic shifts, but the more pressing problem of bad growing seasons.

Better flood control and prevention, weather forecasting and more responsive emergency services all help reduce the damage from floods. Never have we been better at protecting ourselves against nature. If the past is any guide to the present, that's how we'll deal with further changes in climate (whether caused by human activity or not): through adaptation. …
