Seven years left to reverse the CO2 emissions trend 2


Carbon dioxide and greenhouse gases emissions have been increasing continuously since the beginning of the industrial revolution at the end of the 18th century.

According to the IPCC experts who met the EU environment ministries today, this trend have to be reversed and emissions have to start decreasing within the next seven years.

To these experts, the European Union can lead the way and set an example. This meeting took place as the G8 representatives are meeting on climate change.

As the Agence France Presse states :

The head of the UN’s Nobel-winning panel of climate scientists on Friday said only seven years remained for stabilising emissions of global-warming gases at a level widely considered safe.

Rajendra Pachauri, chairman of the Intergovernmental Panel on Climate Change (IPCC), delivered the bleak warning at a gathering of European Union ministers where he pleaded with the EU to take the lead in global talks on tackling climate change.

The UN negotiations “must progress rapidly, otherwise I am afraid that not only future generations but even this generation will treat us as having been irresponsible,” said Pachauri.

“The EU has to lead. If the EU does not lead, I am afraid that any attempt to bring about change and to manage the problem of climate change will collapse,” said Pachauri.

“Today there is a high level of expectation. If the EU does not lead, you will not be able to bring the US on board, North America, on board. You will not be able to bring on board other countries in the world as well.”

Pachauri said the IPCC’s Fourth Assessment Report — which helped earn the panel the 2007 Nobel Peace Prize alongside US climate campaigner Al Gore — had dispelled any doubts about human impact on the climate system.

He issued a stark warning that time was running out for dealing with the threat.

In the 20th century, the temperature had already risen on average by 0.74 degrees Celsius (1.32 degrees Fahrenheit), he said.

The EU wants to limit the overall warming since pre-industrial times to 2 C (3.6 F), a goal that is shared by many scientists.

To do this, said Pachauri, “we would have to stabilise the greenhouse-gas concentration at more or less the level at which we are today.

“(…)But in order to do that, we have a window of opportunity of only seven years because emissions will have to peak by 2015 and reduce after that. We cannot permit a longer delay.”

Pachauri also sounded a note of caution about the 2 C (3.6 F) figure, as evidence was mounting that climate change was accelerating faster than thought. Heatwaves and floods were increasing, and higher temperatures were having a far-reaching effect on glaciers and snowfall.

“The very wise target that the EU had set of 2.0 (C, 3.6 F) may need to be looked at once more, because the impacts are turning out to be more serious than we had estimated earlier,” he said.

Talks are taking place under the UN Framework Convention on Climate Change (UNFCCC) for a new global pact after 2012, when the current provisions of the Kyoto Protocol run out.

A major round of negotiations will take place in Poznan, Poland in December, with the climax scheduled in Copenhagen in December 2009.
