Tropical deforestation currently accounts for nearly 20 percent of carbon emissions that cause global warming. A group of forest-rich developing nations have called for a strategy to make forest preservation politically and economically attractive. The result is a two-year initiative to assess key issues and policy approaches, “Reducing Emissions from Deforestation” (RED), launched by the United Nations Framework Convention on Climate Change.
The study comes as international climate negotiations are taking place this week in Bonn, Germany. There, policymakers are negotiating the design of international climate policies after the first commitment period of the Kyoto Protocol expires in 2012. On the table is a proposal put forward by the governments of forested developing countries who are seeking to reduce their emissions from deforestation in return for access to financing through the global carbon market.
An international team of eleven top forest and climate researchers* including Pierre Friedlingstein, a researcher at the French National Research Centre (CNRS), found that cutting deforestation rates in half by mid-century would account for up to 12 percent of the total emissions reductions needed to keep concentrations of heat-trapping gases in the atmosphere at safe levels.
Dr Canadell, co-author and executive director of the Global Carbon Project, says that while tropical deforestation will continue, slowing the amount of clearing will make significant impacts. “If by 2050 we slow deforestation by 50 per cent from current levels, with the aim of stopping deforestation when we have 50% of the world’s tropical forests remaining, this would save the emission of 50 gigatonnes of carbon into the atmosphere. This 50/50/50 option would avoid the release of the equivalent of six years of global fossil fuel emissions.”

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:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
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...
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...
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,...
