New global analysis shows 400% increase in carbon dioxide emissions growth

13.11.2006
The global growth in carbon dioxide emissions from fossil fuels was 4 times greater in the period between 2000 to 2005 than in the preceding 10 years, say scientists gathering in Beijing today for an international conference on global environmental change.

Despite efforts to reduce carbon emissions, the global growth rate in CO2 was 3.2% in the five years to 2005 compared to 0.8% in the period 1990 to 1999, according to data soon to be published by the Global Carbon Project (www.globalcarbonproject.org), a component of the Earth System Science Partnership (www.essp.org).

“This is a very worrying sign,” said Dr Mike Raupach, Chair of the Global Carbon Project. “It indicates that recent efforts to reduce emissions have virtually no impact on emissions growth and that effective caps are urgently needed.”

Carbon dioxide emissions over the last five years are close to one of emissions scenarios from the Intergovernmental Panel on Climate Change (IPCC) called “A1B”. This scenario assumes that 50% of energy over the next century will come from fossil fuels, and leads to unacceptably high atmospheric CO2 concentrations.

“On our current path, we will find it extremely difficult to rein in carbon emissions enough to stabilise the atmospheric CO2 concentration at 450 ppm and even 550 ppm will be a challenge,” said Dr Josep Canadell, Executive Director of the Global Carbon Project. “At some point in the near future, we will miss the boat in terms of achieving acceptable levels of carbon dioxide in the atmosphere.”

Due to the phenomenon of environmental inertia, even when anthropogenic emissions do begin to decrease, atmospheric CO2 will continue to rise for up to as much as a century. Global temperatures will continue to increase for two or more centuries locking the world into continuing climate change for this period. Effective management of Earth system inertia depends on early and consistent actions.

The analysis was commissioned by UNESCO and will be presented at the COP12 climate talks in Nairobi this week.

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Im Focus: Glacier bacteria’s contribution to carbon cycling

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.

A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
