Greenhouse gases than any record – The Press

 

Greenhouse Gases over each record

 

 According to a new report, the World Meteorological Organization are confirmed record concentrations of greenhouse gases in the atmosphere. Meanwhile, the sea is acidifying at a rate never occurred in 300 million years

The prognosis is grave. Even more acute than scientists previously predicted. According to a new report, obtained in advance by The Press of the World Meteorological Organization, the World Meteorological Organization has been confirmed record of the concentration of greenhouse gases in the oceans and the atmosphere, particularly carbon dioxide, CO2, the most climate-impacting gases.

Apparently the Greenhouse Gas Bulletin, the title of the document, it might be branded as “yet another report on changes in the climate.” Unlikely to this document will cause public panic and hysteria as happened with the serious outbreak of Ebola. Yet the numbers are those which, read with glasses of science, disturbing and frightening. Suffice it to say that the concentration of CO2 in the atmosphere is 142% higher than the pre-industrial era (ie since 1750), methane 253 and 121 times that of nitrous oxide. Some levels have already been reached in the long history of the planet. But never at a speed so extraordinary.

In addition, according to new figures between 1990 and 2013 there was a 34% increase in radiative forcing, the complex effects that alter the balance of the solar energy that is retained in the system atmosphere -land. Energy in the form of heat which leads to an increase in average temperatures ranging from strongly destabilize the planet.

Care explains the Secretary General of the World Meteorological Organization Michel Jarraud is to “urgently reduce emissions of greenhouse gases,” to avoid the crazy weather can radically alter our way of life. In December it expected a new round of negotiations in view of the Paris Conference of 2015 which should lead to a global climate agreement to reduce emissions of greenhouse gases. Six years after the failure of Copenhagen may be the only opportunity in this decade to reach an agreement.

On the table in the UN negotiators will find other alarming data from this Greenhouse Gas Bulletin. Like the fact that the amount of CO2 in the atmosphere has increased in 2012-2013 than in any other year since the early eighties. “The data show that, rather than decreasing as expected, the concentration of greenhouse gases has increased last year in an unprecedented speed record for the last 30 years. We need to stop this trend. And we do not have much time left. ”

Not only are increased emissions of greenhouse gases produced by human activity, also decreased the absorption capacity of these as part of nature. According to climatologists this symptom is among the most serious of those shown by the patient. The oceans act as a mechanism for reducing the concentration of CO2 through algae and other marine organisms. Today, however, even the oceans have reached a degree of saturation. The new data show in fact that the increase in ocean acidification (related to the CO2 absorbed) has reached a speed for Paleoclimatologists has never been recorded in the last 300 million. That is when there were still dinosaurs. “The carbon dioxide remains in the atmosphere for hundreds of years, and even longer in the oceans. Emissions past, present and future will have a cumulative impact on global warming is that in the acidification. The laws of physics are not negotiable, added Mr Jarraud.

According to several respondents Greenhouse Gas Bulletin is one of the most accurate and reliable scientific documents. “I’m forty years that we talk about climate change. Between denial and hypocrisy, politics, struggle to understand the seriousness and complexity of the situation, “says Federico Antognazza of Italian Climate Network, the leading association of Italian climate. “We have to take seriously documents like this that analyze the seriousness of the situation. These weather events will impact our agriculture, our sea, will put at risk many geographical areas of the country. The scientific data are more abundant: we really have to wait for it to exceed the threshold of 2 ° C, to see what lies beyond the abyss climate? “

To raise awareness of the Government’s action Renzi the world Italian environmentalist, an unprecedented network of alliances, will meet in Rome on September 21, to take to the streets in support of the great March for the Climate to be held in New York. Data in hand, asking for a new action strategy for reducing greenhouse gas emissions.
