Remaining CO2 emission 'quota' may be used up in one generation and more than half of all fossil fuel reserves may need to be left untapped
Carbon dioxide emissions, the main contributor to global warming, are set to rise again in 2014 - reaching a record high of 40 billion tonnes.
The 2.5 per cent projected rise in burning fossil fuels is revealed by the Global Carbon Project, which is co-led in the UK by researchers at the Tyndall Centre for Climate Change Research at the University of East Anglia and the College of Engineering, Mathematics and Physical Sciences at the University of Exeter.
It comes ahead of the New York Climate Summit, where world leaders will seek to catalyse action on climate change.
This latest annual update of the Global Carbon Budget shows that total future CO2 emissions cannot exceed 1,200 billion tonnes – for a likely 66 per cent chance of keeping average global warming under 2°C (since pre-industrial times).
At the current rate of CO2 emissions, this 1,200 billion tonne CO2 'quota' would be used up in around 30 years. This means that there is just one generation before the safeguards to a 2oC limit may be breached.
The international team of climate scientists say that to avoid this, more than half of all fossil fuel reserves may need to be left unexploited.
Prof Corinne Le Quéré, Director of the Tyndall Centre at UEA, said: "The human influence on climate change is clear. We need substantial and sustained reductions in CO2 emissions from burning fossil fuels if we are to limit global climate change. We are nowhere near the commitments necessary to stay below 2°C of climate change, a level that will be already challenging to manage for most countries around the world, even for rich nations.
"Politicians meeting in New York need to think very carefully about their diminishing choices exposed by climate science."
The annual Global Carbon Budget, published today, includes a projection for 2014, as well as figures for 2013 by country and per capita. It is accompanied by a series of papers in Nature Climate Change, Nature Geoscience and Earth System Science Data Discussions.
Lead author of the Nature Geoscience paper, Prof Pierre Friedlingstein, from the University of Exeter said: "The time for a quiet evolution in our attitudes towards climate change is now over. Delaying action is not an option - we need to act together, and act quickly, if we are to stand a chance of avoiding climate change not long into the future, but within many of our own lifetimes.
"We have already used two-thirds of the total amount of carbon we can burn, in order to keep warming below the crucial 2°C level. If we carry on at the current rate we will reach our limit in as little as 30 years' time - and that is without any continued growth in emission levels. The implication of no immediate action is worryingly clear – either we take a collective responsibility to make a difference, and soon, or it will be too late."

It is accompanied by a Nature Geoscience paper 'Persistent growth of CO2 emissions and implications for reaching climate targets', led by Prof Friedlingstein from the University of Exeter.
Meanwhile 'Sharing a quota on cumulative carbon emissions' led by Dr Michael Raupach director of the Climate Change Institute at the Australian National University, and a comment article 'Betting on negative emissions', led by Dr Sabine Fuss, at the Mercator Research Institute on Global Commons and Climate Change in Germany, are published in Nature Climate Change.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
