This podcast considers whether we can adapt to a changing climate. Our sophisticated global economies face huge challenges, and an effective response requires effective strategies and major investment (unfortunately, there is little evidence of either). Even if we divert a large proportion of GDP to protect our economic infrastructure, it will not be possible to prevent a collapse in the ecosystems that are fundamental to our survival. At what point will human efforts be overwhelmed by Nature? Do we have fifty years? A hundred years? Reports by the UN suggest that adaptation measures will become ineffective if global warming exceeds the 2.0 °C threshold. If this forecast is correct, that gives us about 25 years, if we're lucky.
