Climate milestone? The concentration of carbon dioxide reached record levels

The concentration of carbon dioxide in the atmosphere has reached the highest level in modern history - 400 ppm (parts per million). The data is based on measuring station Mauna Loa, which on Thursday 9 May 2013 exceeded the critical threshold. Data at this moment interim. According to the scientists and activists this level is a milestone for which it is the climate of the planet can begin to change very quickly.

According to the Czech Climate Coalition is the growth of greenhouse gas concentrations in the atmosphere at a rate that greatly complicates expensive and in many cases completely excludes the possibility to adapt to new conditions. Therefore, it is apparently the main solution to reduce greenhouse gas emissions.

"There is no doubt that the value of 400 ppm is incompatible with the goal that gave all operating states in 1992, is to stabilize greenhouse gas concentrations at a level that would prevent dangerous anthropogenic interference with the climate system due to human activity,"
says Jan Hollan of the Centre for Research global change. According to him, due today, and the growing use of fossil fuels, atmospheric concentrations will rise further. "He and all the great statesmen and financiers know that it is necessary to leave fossil fuels in the ground," said Hollan.

Activists can, for example in the Czech Republic with insulation and clean heat sources rid of all gas and coal for home heating. According to Climate Coalition is necessary to adopt a new global binding climate agreement within two years.

The concentration of carbon dioxide is increasing continuously for 200 years. At the beginning of the industrial revolution was approximately 280 ppm, while in 1959 began measuring station Mauna Loa in Hawaii, their activities have reached a concentration of 316 ppm. According to the last measurement reaches 400 ppm. The main cause of increase in the concentration of greenhouse gases, according to scientists and activists burning fossil fuels.

Similarly, a high concentration of carbon dioxide as today was probably in the Tertiary, ruled the earth much warmer climate than today. At that time, the average temperature of two degrees Celsius higher than today and sea levels by 20 to 30 meters higher.
