UN Climate Conference in Bali: World’s top climate scientists call for urgent, tough greenhouse gas limits

07.12.2007
More than 200 leading climate scientists have today warned the United Nations Climate Conference of the need to act immediately to cut greenhouse gas emissions, with a window of only 10-15 years for global emissions to peak and decline, and a goal of at least a 50 per cent reduction by 2050.

The roll-call of top climate researchers includes five University of East Anglia scientists: Prof Corinne Le Quéré (also of the British Antarctic Survey), Prof Andrew Watson, Dr Dorothee Bakker, Dr Erik Buitenhuis and Dr Nathan Gillett.

The signatories warn that if immediate action is not taken, many millions of people will be at risk from extreme events such as heat waves, drought, floods and storms, with coasts and cities threatened by rising sea levels, and many ecosystems, plants and animal species in serious danger of extinction.

The researchers, who include many of the world’s most acclaimed climate scientists, have issued the ‘Bali Climate Declaration by Scientists’ in which they call on government negotiators from the 180 nations represented at the meeting to recognize the urgency of taking action now. They say the world may have as little as 10 years to start reversing the global rise in emissions.

Prof Le Quéré said: “Climate change is unfolding very fast. There is only one option to limit the damages: stabilise the concentration of CO2 and other greenhouse gases in the atmosphere.

“There is no time to waste. I urge the negotiators in Bali to stand up to the challenge and set strong binding targets for the benefit of the world population.”

The Bali Declaration emphasises the current scientific consensus that long-term greenhouse gas concentrations need to be stabilised at a level well below 450ppm CO2e (450 parts per million measured in carbon dioxide equivalent).

Building on the urgency of the recent Synthesis Report of the Intergovernmental Panel on Climate Change (IPCC) released on 17 November in Valencia, Spain, the declaration calls on governments to reduce emissions “by at least 50 per cent below their 1990 levels by the year 2050”.

The Bali Declaration endorses the latest scientific consensus that every effort must be made to keep increases in the globally averaged surface temperature to below 2 degrees C. The scientists say that “to stay below 2 degrees C, global emissions must peak and decline in the next 10 to 15 years”.

The critical reductions in global emissions of greenhouse gases and the atmospheric stabilisation target highlighted in the Bali Declaration places a tremendous responsibility on the Bali United Nations Framework Convention on Climate Change.

Negotiations at Bali must start the process of reaching a new global agreement that sets strong and binding targets and includes the vast majority of the nations of the world. The Bali Declaration concludes:

“As scientists, we urge the negotiators to reach an agreement that takes these targets as a minimum requirement for a fair and effective global climate agreement.”

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
