From the Guardian - Ten years ago the leading economist warned about climate change in a landmark report – he says while there is cause for optimism, the picture is still grim
"A lot has happened since Nicholas Stern, then a permanent secretary at the Treasury, produced his landmark review of the impact of climate change 10 years ago. His work was quickly recognised as the definitive account of the economic dangers posed to the planet by global warming.
Since then, global temperatures have risen to record levels. Arctic summer sea ice has continued to shrink, as have many major land-based ice sheets. Carbon dioxide is being pumped into the atmosphere in ever-increasing amounts. At the same time, low-lying coastal areas, such as south Florida and parts of Bangladesh, are experiencing more and more flooding as sea levels have risen. Scientists have begun to link extreme weather events to the planet’s changing climate, while animal and plant species are gradualling moving towards the poles. So, a decade on, is Stern plunged in despair over our prospects? Not quite. While the picture is certainly grim, the world’s top climate economist still believes there are grounds for modest optimism.
“We have been too slow in acting on climate change,” he told the Observer. “In particular, we have delayed the curbing of greenhouse gas emissions for far too long. When we published our review, emissions were equivalent to the pumping of 40-41bn tonnes of carbon dioxide into the atmosphere a year. Today there are around 50bn tonnes of carbon dioxide equivalent. At the same time, science is telling us that impacts of global warming – like ice sheet and glacier melting – are now happening much more quickly than we anticipated.”
