Russias far northwestern regions witnessed a surge in warm weather in July, with air temperatures soaring 3-4 degrees Celsius above average, according to Tatyana Pozdnyakova, the chief meteorologist at the Meteonovosti news agency.Naryan-Mar, the administrative center of the Nenets autonomous district in the Arctic, saw temperatures rise to 31.6 C on July 31, breaking the previous record high of 31 C set in 2010.In Vorkuta, another city beyond the Arctic Circle and situated in Russias republic of Komi, air temperatures exceeded 27 C, the highest level since 1993.The high temperatures continued into August, with Naryan-Mar recording 30.2 C and Vorkuta measuring 24.1 C on Tuesday.Pozdnyakova said Julys historic heat in some of Russias Arctic regions was caused by a warm front pushed in from Kazakhstan.Meanwhile, a different trend was taking shape in parts of Russias Far East, where temperatures in some towns saw record lows.In Srednekolymsk, located in the republic of Sakha, temperatures fell to a record low of minus 0.3 C on July 31.According to Meteonovosti, even in Russias far northern regions, negative departures are unusual for the month of July.Climate scientists say that heat waves have become more frequent and intense as a result of human-induced climate change.However, historic low temperatures can still be recorded, but with reduced frequency and duration, according to Roshydromet, Russias state meteorological service.Russia, the world's fourth-largest emitter of greenhouse gases, is experiencing a rise in temperatures twice as fast as the world as a whole,Roshydromet says, with warming taking place in all seasons of the year.In Russia's Siberian and Arctic regions, these warming temperatures have contributed to permafrost melt, which releases potent greenhouse gases into the atmosphere and damages infrastructure.Globally, July 2023 is expected to be the worlds hottest month on record.
