Burning coal is the world's most carbon intensive energy source. In fact, this single energy source accounts for around one third of the world's total greenhouse gas emissions. But even as international calls to stem climate change have grown louder, coal-use is booming in China. In 2011, coal consumption jumped 9 percent. Last year, a report found an addition 363 coal-fired plants under proposal in China.
China jumped past the U.S. as the world's largest emitter of greenhouse gases in 2006, however the U.S. still remains the largest emitter historically. Neither the U.S. or China has comprehensive legislation in place to cut greenhouse gas emissions.
In a recent report the International Energy Agency warned that two-thirds of the world's known fossil fuel deposits must stay in the ground, if the world is have even a fifty-fifty chance of keeping global temperatures from rising above 2 degrees Celsius. Scientists say rising above this threshold would likely lead to catastrophic climate change, and the world nations—including China and the U.S.—have pledged to keep global temperatures below this level.
Mercury hurts birds and people: what we can learn from studying our feathered friends
(01/07/2013) Birds aren't that different from people. We learn from our parents, just like zebra finches learn songs from their fathers. We are active and noisy during the day, like birds, and we can also be territorial. Also like birds, we try to attract mates through colorful displays and beautiful songs. Birds are sensitive to pollution in their environment just like we are: harmful elements such as mercury wreak similar havoc on human and bird biology alike. Because our species share so many attributes, studying birds illustrates the connections between them and us.
Wealthy nations' fossil fuel subsidies dwarf climate financing
(12/05/2012) A new analysis finds that 21 wealthy countries spent five-times more on subsidizing fossil fuels in 2011 than they have on providing funds for poor nations to cut greenhouse gas emissions and adapt to the impacts of climate change. The analysis, by Oil Change International, comes in the midst of the current UN Climate Summit held in Doha, Qatar; progress at the talks has been stymied due to the gulf between poor and rich nations, including on the issue of climate financing.
'No-one is listening to the entire scientific community': global carbon emissions set to hit new high
(12/03/2012) Global carbon dioxide (CO2) emissions from industrial sources are set to hit a new record high this year according to a new analysis by Global Carbon Project. The analysis in Nature Climate Changes predicts that CO2 emissions will rise another 2.6 percent, hitting 35.6 billion tonnes. The scientists warn that such steep climbs in global emissions year-after-year means that the door is rapidly closing on a global agreement to keep temperatures from rising 2 degree Celsius (3.6 degrees Fahrenheit) above pre-industrial levels.
China and India plan 818 new coal plants
(11/26/2012) Even as the clamor to reduce greenhouse gas emissions reaches a new high—echoed recently by such staid institutions as the World Bank and the International Energy Agency (IEA)—a new analysis by the World Resources Institute (WRI) finds that 818 new coal-fired plants are under proposal in China and India. In all 1,199 new coal-fired plants are currently planned worldwide, according to the report, totaling 1.4 million megawatts of energy.
Indian coal giant targets forests
(11/18/2012) The world’s largest coal producer, the state-run Coal India Ltd., plans to massively expand mining in forest areas to help meeting surging demand for electricity, reports The Wall Street Journal.
U.S. carbon emissions lowest since 1992
(08/01/2012) A shift away from coal and reduced gasoline demand coupled with a mild winter led to an 8 percent drop in U.S. carbon dioxide emissions during the first quarter of 2012, reports the Energy Information Administration. Emissions between January and March 2012 were the lowest since 1992.
Tigers vs. coal in India: when big energy meets vanishing cats
(08/01/2012) Burning coal fuels climate change, causes acid rain, and spreads toxic pollutants into the environment, but now a new Greenpeace report warns that coal may also imperil the world's biggest feline: the tiger. Home to world's largest population of tigers—in this case the Bengal subspecies (Panthera tigris tigris)—India is also the world's third largest coal producer. The country's rapacious pursuit of coal—it has nearly doubled production since 2007—has pushed the industry into tiger territory, threatening to destroy forests and fragment the tiger's already threatened population.
Prominent climate skeptic reverses course, says global warming worse than IPCC forecast
(07/30/2012) After starting his own project to study global warming, a once-prominent climate change skeptic and physicist says he now accepts the reality of anthropogenic climate change. "Last year, following an intensive research effort involving a dozen scientists, I concluded that global warming was real and that the prior estimates of the rate of warming were correct. I'm now going a step further: Humans are almost entirely the cause," Richard Muller writes in the New York Times as his team, the Berkeley Earth Project, releases a new paper that finds an even stronger link between greenhouse gas emissions and rising temperatures worldwide than the Intergovernmental Panel on Climate Change (IPCC).
China's per capita emissions nearly as high as Europe's
(07/19/2012) The average person in China emitted 7.2 tons of carbon last year, according to new figures from BL Netherlands Environmental Assessment Agency and the European commission's Joint Research Centre (JRC). This means that the average Chinese citizen is now very close to the average European, who emits 7.5 tons, in terms of annual emissions. Having been named the world's largest emitter of greenhouse gases in 2009—usurping the U.S. from its long-held position—China continues to lead the pack with emissions that rose 9 percent in 2011.
