Climate change is happening faster than expected

Ahead of the global climate change conference, leading climate scientists have released a detailed report on the negative effects of climate change on Earth. At the same time, the report is named Copenhagen Diagnosis, which also requires world leaders to take stronger actions to reduce greenhouse gas emissions.

Dr. Andrew Weaver, meteorologist at Victoria University (Australia), said world leaders need to commit to making legal decrees to reduce emissions to the environment. Otherwise, the world will have to say 'goodbye' with the goal of keeping the global temperature rising by no more than 2 degrees Celsius - an acceptable level, in this century.

Dr. Weaver and 25 colleagues from climate forecast centers in Europe, North America and Australia said their report as a general science book on climate change for the great from 192 countries around the world at the conference on global climate change organized by the United Nations in Copenhagen (Denmark) on December 7.

"They need to know the not-so-real truth about global warming and the unpredictable hazards caused by this phenomenon," said Dr. Hans Joachim Schellnhuber, Chairman of the German Advisory Council on change. Global and co-author of this report, said.

From the evidence presented about the impacts of climate change from the Arctic to the Amazon region, the report says climate change is happening faster than we think and requires urgent action. to reduce CO2 emissions.

If emissions continue to increase today, this report predicts that global temperatures will increase by 4 to 7 degrees Celsius by 2100. If this forecast becomes a reality, there are people and all births. The situation on Earth will be deeply affected by the consequences of climate change.

The majority of the authors of this new report are also the authors in the report of the Intergovernmental Panel on Climate Change (IPCC), which was launched by the United Nations in 2007. The IPCC report was made available. report on climate change and its effects. This new report is updated from the IPCC report.

To prove that climate change took place faster than expected, the Copenhagen Diagnosis report produced data on melting ice in the Arctic. Specifically, from 2007 to 2009, melting ice speed here is 40% higher than the rate predicted in the IPCC report.

Sea level has also increased by 5cm over the past 15 years, 80% higher than the expected increase. Scientists warn that sea levels could rise by 1 meter by 2100. If this happens, more than 160 million people will have to find a new place to live.

In 2008, carbon dioxide emissions from fossil fuels were 40% higher than in 1990, although annual international conferences still set targets, promising to cut CO2 emissions. discharged into the environment. Finally, the report recommends that global emissions be further cut to avoid the worst effects of climate change.

"It is necessary to create a turning point for climate change soon ," scientists said. "To keep the global climate stable, it is necessary to reduce CO ₂ emissions and effect emissions." greenhouses in this century '.

The report also urged governments to support the plan to require developed countries to achieve their goal of reducing emissions to less than 25% and to assist developing countries to further reduce gas emissions. greenhouse gas emissions to minimize the effects of climate change.
