Leading climate scientists said that the current heat wave in Siberia, where the thermometer reached a record of 38 degrees Celsius, impossible if not to take into account the impact of anthropogenic climate change. The real reason for the catastrophic heat wave edition of Science Alert.
the Researchers found that a record high temperature was two degrees higher than in the hypothetical absence of greenhouse gas emissions for decades. The values of the columns of thermometers rose to five degrees above average in the period from January to June. The temperature in Verkhoyansk (Yakutia) was recorded at 38 degrees Celsius, which exceeds previous records.
the relation between the extreme heat and anthropogenic human impact on the biosphere were obtained using the methods of attribution of climatic changes, intended to determine the causes of global warming. Scientists simulated modern climate, which is about one degree warmer than the climate in pre-industrial times, and compared it with the model, the generating temperature in Siberia without human influence, i.e. without taking into account additional degrees.
it Turned out that the heat are seeing now should not occur more than once every 80 thousand years. However, human influence has increased the probability of this event is at least 600 times.
Scientists believe that the extreme heat has caused forest fires, covering 1.15 million acres and released millions of extra tons of carbon dioxide into the atmosphere. Also, increased thawing of permafrost, which contributed to the depressurization of the oil tank and a catastrophic oil spill in Norilsk in may.
