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.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
