Although greenhouse gas emissions continue to rise at an alarming rate, governments are beginning to embrace carbon-cutting initiatives, while technological advances are sharply reducing the cost of deploying solar and wind power, according to the latest report by the Intergovernmental Panel on Climate Change.
The working group report on climate mitigation, released in Berlin, said that global CO2 emissions have risen about 2.2 percent a year this century — twice the rate of the last few decades of the 20th century — and that holding temperature increases to 2 degrees C (3.6 F) can only be achieved through an intensive push over the next 15 years.
But the report also said that the political will to reduce carbon emissions seems to be rising around the world, and that shifting the global energy system from fossil fuels to zero- or low-carbon sources would reduce economic growth by only about .06 percent per year. “The loss in consumption is relatively modest,” said IPCC chairman Rajendra Pachauri. “The longer we delay the higher would be the cost.”
There may be a cheaper and unexpected way to cope with energy problems.
