learned that the report of the Intergovernmental Panel on Climate Change, published today, says the man responsible for the increase in carbon dioxide.
human action causes "most likely" global warming. In technical terms, means that the possibility that human action is the cause of the greenhouse effect is above 90%.
This is the main conclusion that transcended the Intergovernmental Panel on Climate Change (IPCC, its acronym in English), held in Paris and ending today with the publication of a report that explains and analyzes the evolution of global warming, its causes and its possible development.
In subsequent meetings, the experts will discuss how to adapt to change, ways to combat it and the costs that represents the greenhouse effect.
On the last day of session, global warming experts have spoken with bureaucrats from more than 100 countries, at a vigil that could affect policies in the world. Chile was represented by Fernando Farias, a member of the National Environment Commission (CONAMA).
Earth's temperature will rise between 3 ° and 4.5 ° Celsius over the next years, unless we stabilize the concentration of carbon dioxide (CO2) at 550 parts per million. Today, the concentration is 380 parts per million.
phenomena such as droughts, floods and cyclones will increase its frequency and impact, affecting the economy of nations and can produce 200 million refugees by the end of the century.
Faced with these estimates, the experts urged to strengthen the Kyoto Protocol, which has not yet been ratified by the United States, the largest polluters in the world (producing nearly 40% of global CO2).
During the report discrepancies arose with such matters as how sea \u200b\u200blevel rise and how global warming affects the storm surge. This is because data on the melting of Antarctica and Greenland is not yet considered in the latest research. It is estimated that by 2100 will rise 58 centimeters. The different approaches differ in cost and urgency about the problem and questioned how closely some reality. Potsdam Institute experts noted that the projections of the report may underestimate the reality of its development, because some events occur more quickly than expected.
occasion of the publication of this report, the French environmental group Alliance for the Planet called on world citizenship to make a global failure to warn of the danger posed by climate change.
network for circulating an email inviting to turn off the lights at the same hour (between 19:55 and 20:00 local time). "For five minutes will not consume energy," reads the text. The initiative has the support of several municipalities in Europe. Monuments like the Eiffel tower and the building of the European Parliament joined the event.
parallel, the World Water Council, meeting in Algeria, called for reducing potable water consumption, it is as important as reducing energy expenditure. The demand for water is growing disproportionately compared to only hÃdricos.AUMENTOSLA resource growth temperature of the Earth will rise between 3 ° and 4.5 ° Celsius by the end of the century. Since the industrial age has risen by 0.7 ° Celsius.
