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.
