The chart above shows the Earth's climate warming over the period January-May 2007 compared to the same period on an average 1961 to 1990.
As can be seen, the warming is not uniform. It is more pronounced in Europe and Russia. There's even a cooling in some areas of the North Pacific and Antarctic oceans. By cons, where it warms up seriously, as in Siberia it reaches values of + 5 ° C in less than 20 years! This only accelerates the melting of permafrost , which will release more CO2 and methane into the atmosphere.
May 28, Russia has experienced an unprecedented heat wave. The temperature in Moscow reached 32.9 ° C. The previous temperature record date of May 1891 with 31.8 ° C. This is the first time in 128 years that the temperature in Moscow exceeds 30 ° C in May.
