results suggest that there may be untapped potential for mitigating climate change by reducing emissions of soot
soot from wood smoke and diesel exhaust can have twice the impact on global warming than previously thought, according to a new study released Tuesday.
The "black smoke" is said to be the second largest artificial agent of climate change.
The results, published in the Journal of Geophysical Research, Atmospheres suggest that there may be untapped potential for mitigating global warming by reducing emissions of soot.
huge amounts of soot by man into the atmosphere each year. Approximately 7.5 million tonnes, was published only in 2000, according to estimates. A greenhouse effect which carbon dioxide and more than two thirds of methane.
The main source of soot emissions is the burning of forests and savannah grasslands. But diesel engines account for about 70% of emissions from Europe, North America and Latin America.
In Asia and Africa, wood, home fires account for 60% and 80% of soot emissions. Coal fires are also a major source of soot in China, parts of Eastern Europe and the countries of the former Soviet bloc.
soot warms the atmosphere by absorbing the sun's heat incoming and scattered.
Dr. David Fahey, co-author of the U.S. National Oceanic and Atmospheric Administration (NOAA), said: "This study confirms and extends beyond other research suggesting carbon black a strong warming effect just before methane. " His colleague, Professor Piers Forster from Leeds University, Earth and Environment, said. "There are exciting opportunities for cold climate by reducing emissions of soot, but not simple 
"Reducing emissions from diesel engines and interior wood and coal fires is obvious that there Tandem health and climate benefits.

imagine that two families - one rich and the other hard-up - could eat in the future
Predict what will eat in Britain in 2035 is reduced to the sad thing is the future. Is that the stagnation of growth have pushed down the list of rich countries to date we can not import food more? Or new sources of energy and acceptance of biotech foods means that 3-D printers pumped food burgers and sushi nutritionally enriched in all our houses? Climate change means land in Britain to devote to crops, and not in the flesh, to keep us fed 70 million?
Familyhard-up
more food as much as we can in the yard. The cost of food used almost half of household income, compared to only 12% of our grandparents, while we take very little.
Brown bread
The Ministry of Food has decreed that refined flour lost too many vitamins and minerals, and has banned white bread (as Britain did in the Second World War). Price of wheat flour rose with the collapse of the arable land in India, southern Russia and the United States, Britain, and it is not serious.
meat Lab
father does not eat "Frankensteaks" - he would rather have a lobster egg-culture - but the rest of the family eats "the seaweed farm" bioreactor grown meat (we did love it things in proteins recovered from wastewater).
potatoes
potatoes every day of the week until the dough is made from flour, potatoes. The potato is the staple carbohydrate, although experts are concerned about our growing dependence on it - the only pope dependence led to the Irish potato famine that killed a million people. GM made a blight that has resisted, but still emerging diseases and survive any old varieties.
rice
The richest part of the world - South Asia - eat all the rice they produce, so importing is expensive and attempts to grow rice in wetlands have new Thames Estuary borne fruit. Rice we buy is made of reconstituted potato or barley. By law, all brands contain nano-capsules of vitamins and nutrients.
cheese and butter livestockFew in Britain, with the exception of dairy products. Cows are an effective way to convert plant material in animal fat, as long as there is not enough water. Our city street has its own small herd of cows genetically modified in collaboration managed on the grass made striking gardens. As our medieval ancestors, now receives most of our fats, and proteins necessary for milk, cheese and butter.
fish
carnivorous fish are a rare treat. Even the most advanced transgenic salmon farms still have to consume three grams of fish to produce another one of their own. Thus, the consumption of fish vegetarian, grown in the solar heating is AquaFarm - developed from tropical species such as tilapia and catfish, and modified with genes from lemon, tomato or grass cover basic taste muddy. By law, all omega-3 have added to their diet.

The wealthy family A unique project encourages students to make films about the creation of a sustainable world for their own children
Aa> Youth from across Europe working with broadcasters to create movies on improving their environment. What are the things you can do to make a big change? How can all do something to make them more sustainable world? Simple. Each must do some. This is the idea of ??Power Bits.Bits
energy involves 13 partners from nine countries in Europe and beyond, and is supported by the Intelligent Energy Europe program. His ambition is to achieve behavioral changes and promote innovative practices in energy efficiency and renewable energy use in the daily lives of young people. is a project that goes beyond the standard methods of communication, instead of using platforms mixed distribution, such as television programs on national television and satellite channels dedicated niches as platforms and games.Power Bits
for youth, encouraging them to create their own content to reinforce messages sustainable energy - and the really exciting part for them is that this content will be shown across Europe through these channels broadcast nationally and on the web. The project has already produced 24 documentaries, an interactive web documentary and a game three of the documentary, made in the UK with the students of the school, appearing on the science channel own guardian Newton. The first of these films, games recycled (see here), follows a group of students as they discover for themselves if the 2012 London Olympic Stadium was as green as everyone claims . They also learn from games how to make your own life more sustainable, even creating their own recycled product added to the Olympic Park. top of this, the young people in schools across Europe now have the opportunity to share their views and ideas on the future of the planet in another part of the project "your voice ". It does what it says on the tin. It allows young people to express their views in a video international competition for secondary schools. It aims to raise awareness and increase knowledge about energy saving, renewable and sustainable issues among young Europeans, mainly through his own filmmaking skills. A young student of 18 years old are invited to send their e-bits ideas on a more sustainable future, create and upload a short video message - no more than three minutes - explaining what must be manufactured from your point of view.topics that can be considered as renewable energy, energy efficiency in end-use, sustainable transport, recycling and / or reuse. The contest is open to all nine European countries: Belgium, Czech Republic, Germany, United Kingdom, Greece, Italy, Slovenia and Spain. However, any student anywhere in the world can upload his / her video and enter the contest. All videos will be posted on YouTube Bits channel power.
The competition has three categories of awards:. Best original idea
. The best scientific description and content . successful publicVideo
the winner of each category will be broadcast on all television and European companies involved in the project. The winners will be invited to Brussels for a special tour to visit the European Commission and meet all project partners. students and young people can upload your video independently or work with schools and teachers. There are tips on the website of Energy Bits video on how to make a good video, and if someone needs more help they can benefit from the experience of the media and scientific partners in Power Bits consortium. These people are all available through platforms energy Bits / blog, to support students in their video production. Before starting his own production, you can take a look at this little energy documentary filmed in Europe in terms of different energy. Some of them are funny, others a little more serious, and some are totally crazy! If you want to learn the issues related to energy consumption can play Energy2020 serious game. There will be different situations related to energy, with the possibility to save the world ... Will they be able to repair all damage caused by adults? Thus, the energy Bits is an opportunity for all young people to improve their knowledge of energy issues and sustainable development. But more than that, it is an opportunity for the adult community across Europe to listen and take suggestions from young people to achieve the improvement of the environment in everyday life.Click here

delegates worked through the night to reach agreement on key issues such as the Kyoto Protocol, but remain hopeful rescue plan
negotiations on a new climate agreement land through Friday night in Qatar, as countries could not agree on key issues such as: to save the Kyoto Protocol, the finance and compensation for poor countries suffering the effects of climate change, and how to structure a proposal for a new global agreement on climate change.
negotiations, which lasted more than two weeks, seemed destined to last Saturday. But the marathon session left many delegates hoping to salvage a deal in the middle of the frustration and confusion of the night.
"We have worked tirelessly and people realize that we need to go home with something," said one delegate.
The EU is understood to have proposed a deadline of 15:00 on Saturday (24:00 GMT) for the adoption of final amendments, but each time it has established to date the last days of talks have been violated.
Ed Davey, the secretary of energy and climate in the UK, worked all night, meeting with the Ministers of developed and developing countries in order to reach an agreement.
rumors and rumors flew against-the ministers met in small groups and two or three nodes to negotiate compromises. Some meetings were capricious, with delegates aware of the need to avoid a rupture, which would be disastrous for the image of these conversations with the world's eyes on the 195 governments meeting in Doha.
An agreement on the continuation of the Kyoto Protocol beyond the end of this year, when the first set of goals to end seemed at hand. In addition, an agreement to close a parallel set of negotiations following the established protocol entered into force in 2005, at the request of the United States, which has always rejected Kyoto. Close negotiations over unified begin work on a draft new global agreement on climate change, which would require the reduction of emissions of developed countries and developing countries. It would be signed in 2015 come into force from 2020.
One participant said. "It is as if the Qataris think this is a World Cup, but this is not a football game - it's serious negotiations on the future of the planet, they have not taken it to seriously - they have no control. "

WMO figures show the levels of carbon dioxide in the atmosphere has reached a new high last year to 390.9 parts per million
The amount of carbon dioxide that trap heat in the atmosphere has reached a record high of 390.9 parts per million (ppm) in 2011, according to a report released Tuesday by the World Health Organization UN Meteorology (WMO). This is an increase of 40 percent over 1750 levels, before man began burning fossil fuels seriously.
Frustrated by the lack of global action, the World Bank published a report saying that Sunday without significant reductions in emissions, average global temperatures could rise by 4 ° C (7.2 ° F) since by 2060. The report highlighted the disastrous consequences for human health and safety -. Even dangerous rise in sea levels, heat waves and other extreme weather events
But potential disruption of persons and property are so huge that the report is that if there is a warning at least another attempt to revive world leaders after failed attempts during and stops.
Call not only by reducing CO2 emissions, but also an aggressive program to reduce other drivers that global warming might be easier to control, which includes not only the greenhouse emissions absorbers short but powerful, such as methane, but also heat, such as carbon black -. essentially soot

concentration of carbon dioxide in the atmosphere has increased by 20% since 2000, according to a report released days before the climate negotiations in Doha
A UN report on increasing emissions of greenhouse gases has reminded governments of the world Wednesday that efforts to fight against climate change are far from sufficient to meet its stated goal of limiting global warming to 2 ° C.
The report of the United Nations Environment Programme (UNEP), published a few days before the start of major climate conference, said that the concentration of greenhouse gases that trap heat, carbon such as carbon in the atmosphere has increased by 20% since 2000.
scientists say emissions that contribute to climate change and they do not contain could have dangerous consequences, including rising sea levels inundating coastal cities, dramatic shifts in rainfall disrupting the agriculture and drinking water, the spread of diseases and the extinction of species.
emission levels, driven by the combustion of fossil fuels, the need to reduce by 14% in 2020 for the world to reach a path that could limit the increase in global temperature below 2 C compared to pre-industrial levels, UNEP said. This is the stated goal of the UN climate negotiations, which continues next week in Doha, Qatar.
But that will not happen until the country to present ambitious plans to reduce emissions that are currently on the table.
"However, the disturbing fact is that the transition to a low-carbon, green economy, including moving too slowly and the ability to achieve the 44 gigatonnes per year is down" Steiner said.
The report confirmed the scientific evidence that the concentration of greenhouse gases in the atmosphere increases instead of decreasing. On Tuesday, the World Meteorological Organization said that the amount of greenhouse gases in the atmosphere has reached a record high last year.
climate activists said the report highlights the urgent need to promote clean technologies such as wind and solar energy.
