More Sophisticated Forecasts Yield Glimmer of Hope

It finds that growing opposition to biofuels and carbon capture strategies, for instance, could drive up costs of stabilizing atmospheric concentrations of carbon dioxide. But it also finds that these technologies could offer significant co-benefits, such as improved public health. It also finds that policies not specifically targeted at reducing emissions—such as air pollution and energy efficiency regulations—could help reduce emissions. The report is the last of three IPCC reports on climate science and policy.
