Global Carbon Emissions Put Humanity on Tragic Trajectory

WARSAW, Poland – Burning of fossil fuels added a record 36 billion tonnes of CO2 to the atmosphere in 2013, locking in even more heating of the planet.

Global CO2 emissions are projected to rise 2.1 percent higher than 2012, the previous record high, according to a new report released Tuesday by the Global Carbon Project.

This increase is slightly less than the 2000-2013 average of 3.1 percent, said lead author Corinne Le Quéré of the Tyndall Centre for Climate Change Research in the UK.

“This is the second year in a row of below average emissions. Perhaps this represents cautious progress,” Le Quéré told IPS.

Still, these hard numbers demonstrate that the U.N. climate talks have failed to curb the growth in emissions. And there is little optimism that the latest talks known as COP19 here in Warsaw will change the situation even with the arrival of high-level ministers Wednesday.

Global emissions continue to be within the highest scenario of the Intergovernmental Panel on Climate Change (IPCC), she said.

“This is a five-degree C trajectory. It’s absolutely tragic for humanity to be on this pathway,” Le Quéré said.

This year’s 36 billion tonnes of CO2 will raise the planet’s temperature about 0.04 degrees C for thousands of years. Every tonne emitted adds more warming, she said. (If one tonne of CO2 was a second, 36 billion seconds equals about 1,200 years)

CO2 levels in the atmosphere have risen about 40 percent in the last century. The oceans have absorbed 97 percent of the additional heat from those emissions, which is the only reason global temperatures have not risen much faster. However, the oceans will not continue to soak up all the extra heat forever.

Who is most responsible for the 2013 emissions?
