The Global Carbon Project posted the most recent figures for the worlds’ carbon budget, a key to understanding the balance of carbon added to the atmosphere, the underpinning of human induced climate change. Despite the increasing international sense of urgency, the growth rate of emissions continued to speed up, bringing the atmospheric CO2 concentration to 383 parts per million (ppm) in 2007.
Anthropogenic CO2 emissions have been growing about four times faster since 2000 than during the previous decade, despite efforts to curb emissions in a number of Kyoto Protocol signatory countries. Emissions from the combustion of fossil fuel and land use change reached 10 billion tones of carbon in 2007. Natural CO2 sinks are growing but slower than the atmospheric CO2 growth, which has been increasing at 2 ppm since 2000 or 33% faster than the previous 20 years.Dr. Pep Canadell, executive director of the Global Carbon Project said "This new update of the carbon budget shows the acceleration of both CO2 emissions and atmospheric accumulation are unprecedented and most astonishing during a decade of intense international developments to address climate change.”
Emissions growth for 2000-2007 was above even the most fossil fuel intensive scenario of the Intergovernmental Panel on Climate Change (SRES-IPCC). While the developing nations of China and India continue to increase emissions, China has improved the carbon intensity of their economy since 2005, based on data from the National Energy Administration in China.
Decreasing forest cover, almost exclusively from deforestation in tropical countries, was responsible for an estimated 1.5 billion tons of emissions to the atmosphere above what was gained through new plantings. Although the oceans carbon uptake was expected to rise with the higher atmospheric concentration of CO2, in 2007 it was reduced by a net 10 million tons.
Natural land and ocean CO2 sinks, which have removed 54% (or 4.8 billion tons per year) of all CO2 emitted from human activities during the period 2000-2007, are now becoming less efficient. While the size of these sinks continues to grow in response to greater concentrations of CO2 in the atmosphere, they are losing efficiency as feedbacks between the carbon cycle and climate increase.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
