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: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
