Club Moscow

At 4pm local time today in Moscow, Russia, the temperature surpassed 100°F for the first time in recorded history. The high temperature of 100.8°F (37.8°C) recorded at the Moscow Observatory, the official weather location for Moscow, beat Moscow's previous record of 99.5°F (37.5°C), set just three days ago, on July 26. Prior to 2010, Moscow's hottest temperature of all-time was 36.6°C (98.2°F), set in August, 1920. Records in Moscow go back to 1879. Baltschug, another official downtown Moscow weather site, hit an astonishing 102.2°F (39.0°C) today. Finland also recorded its hottest temperature in its history today, when the mercury hit 99°F (37.2°C) at Joensuu. The old (undisputed) record was 95°F (35°C) at Jvaskyla on July 9, 1914. There is little relief in sight, as the latest forecast for Moscow predicts continued highs in the 90s for most of the coming week.

Given that the planet as a whole has seen record high temperatures the past four months in a row, it should not be a surprise to see unprecedented heat waves like the Russian heat wave. A record warm planet "loads the dice" in favor of regional heat waves more extreme than anything experienced in recorded history.... Fourteen extreme national high temperature records have been set in 2010. (Ref)
