This
is the story of the day – nothing else matters.
The figure — among
the most alarming of the latest forecasts by climate scientists —
is at least double the 2C (3.6F) target set by UN members struggling
for a global deal on climate change.
In 2011, global carbon emissions were 54 percent above 1990 levels, according to the research, published in the journal Nature Climate Change by the Global Carbon Project consortium.
“We are on track for the highest emissions projections, which point to a rise in temperature of between 4C (7.2F) and 6C (10.8F) by the end of the century,” said Corinne le Quere, a carbon specialist at the University of East Anglia, eastern England.
“The estimate is based on growth trends that seem likely to last,” she said in a phone interview, pointing to the mounting consumption of coal by emerging giants.
Other research has warned of potentially catastrophic impacts from a temperature rise of this kind.
Chronic droughts and floods would bite into farm yields, violent storms and sea-level rise would swamp coastal cities and deltas, and many species would be wiped out, unable to cope with habitat loss.
Developed countries have largely stabilised their emissions since 1990, the benchmark year used in the UN Framework Convention on Climate Change (UNFCCC) negotiations, the study said.
But this achievement has been eclipsed by emissions by China, India, Brazil and Indonesia and other developing economies, which are turning to cheap, plentiful coal to power their rise out of poverty.
In 1990, developing countries accounted for 35 percent of worldwide output of CO2, the principal “greenhouse” gas blamed for warming Earth’s surface and inflicting damaging changes to the climate system.
In 2011, this was 58 percent.
The temperature projections by the Global Carbon Project are at the top end of forecasts published by scientists ahead of the UNFCCC talks taking place in Doha, Qatar.
The study is based on national carbon dioxide (CO2) data and on estimates for 2011 and 2012. Between 2000 and 2011, CO2 emissions globally rose by 3.1 percent annually on average; for 2012, the rise is estimated at 2.6 percent.
Last year, Chinese CO2 rose by 10 percent, or more than 800 million tonnes, equivalent to Germany’s emissions in an entire year, said the Center for International Cimate and Environmental Research – Oslo (CICERO), whose scientists took part in the paper.
“China is emitting as much as the European Union on a per-capita basis, about 36 percent higher than the global average per-capita emissions,” it said in a press release.

With
Carbon Dioxide Emissions at Record High, Worries on How to Slow
Warming
2
December, 2012
Global
emissions of carbon dioxide were at a record high in 2011 and are
likely to take a similar jump in 2012, scientists reported Sunday
— the latest indication that efforts to limit such emissions are
failing.
Emissions
continue to grow so rapidly that an international goal of limiting
the ultimate warming of the planet to 3.6 degrees, established three
years ago, is on the verge of becoming unattainable, said researchers
affiliated with the Global
Carbon Project.
Josep
G. Canadell,
a scientist in Australia who leads that tracking program, said Sunday
in a statement that salvaging the goal, if it can be done at all,
“requires an immediate, large and sustained global mitigation
effort.”
Yet
nations around the world, despite a formal treaty pledging to limit
warming — and 20 years of negotiations aimed at putting it into
effect — have shown little appetite for the kinds of controls
required to accomplish those stated aims.
Delegates
from nearly 200 nations are meeting in
Doha, Qatar, for the latest round of talks under the treaty,
the United
Nations Framework Convention on Climate Change.
Their agenda is modest this year, with no new emissions targets and
little progress expected on a protocol that is supposed to be
concluded in 2015 and take effect in 2020.
Christiana
Figueres,
the executive secretary of the climate convention, said the global
negotiations were necessary, but were not sufficient to tackle the
problem.
“We
won’t get an international agreement until enough domestic
legislation and action are in place to begin to have an effect,”
she said in an interview. “Governments have to find ways in which
action on the ground can be accelerated and taken to a higher level,
because that is absolutely needed.”
The
new figures show that emissions are falling, slowly, in some of the
most advanced countries, including the
United States. That apparently reflects a combination of economic
weakness, the transfer of some manufacturing to developing countries
and conscious efforts to limit emissions, like the renewable power
targets that many American states have set. The boom in the natural
gas supply
from hydraulic fracturing is also a factor, since natural gas is
supplanting coal at
many power stations, leading to lower emissions.
But
the decline of emissions in the developed countries is more than
matched by continued growth in developing countries like China and
India, the new figures show. Coal, the dirtiest and most
carbon-intensive fossil fuel, is growing fastest, with coal-related
emissions leaping more than 5 percent in 2011, compared with the
previous year.
“If
we’re going to run the world on coal, we’re in deep trouble,”
saidGregg
H. Marland,
a scientist at Appalachian State University who has tracked emissions
for decades.
Over
all, global emissions jumped 3 percent in 2011 and are expected to
jump 2.6 percent in 2012, researchers reported in two papers released
by scientific journals on Sunday. It has become routine to set new
emissions records each year, although the global economic crisis led
to a brief decline in 2009.
The
level of carbon dioxide, the most important heat-trapping gas in the
atmosphere, has increased about 41 percent since the beginning of the
Industrial Revolution, and scientists fear it could double or triple
before emissions are brought under control. The temperature of the
planet has already increased about 1.5 degrees since 1850.
Further
increases in carbon dioxide are likely to have a profound effect on
climate, scientists say, leading to higher seas and greater coastal
flooding, more intense weather disasters like droughts and heat
waves, and an extreme acidification of the ocean. Many experts
believe the effects are already being seen, but they are projected to
worsen.
