CO2 emissions accelerate 400% as world turns to dirtier fuels
Atmospheric carbon dioxide concentrations climbed 2.2 parts-per-million (ppm) in 2007 to 383 ppm. Since 2000 CO2 levels have risen 2 ppm annually, compared with 1.5 ppm during the 1990s, 1.6 ppm in the 1980s, and 1.3 ppm in the 1970s. Rising CO2 levels are the direct result of human activities, including fossil fuel combustion, cement production, and deforestation. The Global Carbon Project’s (GCP) report shows that emissions from fossil fuels and cement have increased 3.5 percent per year since 2000, after increasing at a rate of 0.9 percent during the 1990s. The rate of emissions growth exceeds the highest estimates put forth by the Intergovernmental Panel on Climate Change (IPCC). China is the largest industrial emitter of carbon dioxide (i.e. excluding emissions from deforestation), followed by the United States, E.U. countries, Russia, and India. … – mon
despite years of effort, carbon dioxide emissions are increasing at an alarming rate of 3.5% a year– faster than the 2.7% predicted by the IPCC in their worst case scenario, and miles ahead of the 0.9% annual rise in the 1990s. Worst still, current measures have been based on a middle-ground IPCC scenario. Pep Candell from the Global Carbon Budget told me that this was “astonishing”. For the first time, we have hit 10 billion tonnes of carbon emitted annually. The other thing to note is that China and India are galumphing their way up the table of biggest carbon dioxide emitters. Ten years ago the top four were: USA, China, Russia, Japan. Today that list reads: China, USA, Russia, India – and I am assured by Candell that next year India will have jumped into third place. – nature.com
