This week the IPCC released “Climate Change 2014: Impacts, Adaptation, and Vulnerability”, the second of three reports that will make up the IPCC Fifth Assessment Report (AR5). It follows on from last year’s report that laid out the physical science of climate change – which made clear our prospects of facing global temperature increases of more than 2°C – and up to 5°C – over this century.
This new report investigates the consequences of climate change – looking at impacts and vulnerability across the world. However, there is a fundamental shift of emphasis, with a focus now on adaptation – especially given the serious, but uncertain, impacts that we are likely to face as our climate changes.
There is an interesting graphic in the new report, showing the ‘level of additional risk due to climate change’. It is striking that considerable additional risks occur at even the low end (~ 2°C) of expected warming – and these become increasingly widespread and severe if we end up at the higher end of temperature range.
