According to reports in the Associated Press, on September 1 of 2015, Kiev shattered its all-time record high temperature as readings rocketed to 35.5 C (96 F) in a city stifling under the pall of bog-fire smoke. The city ordered school cancellations and urged restraint in the use of fossil fuel burning vehicles as gray smog choked the city pushing air pollution levels to between 2 and 18 times normal.
For Kiev, it was just one more hot, dry day among many. A heat dome high pressure system has dominated the region for much of late July through early September. And rainfall totals for the past month were just 4 percent of average. Now bogs across a wide swath of Ukraine and Russia are drying out, issuing tell-tale plumes of smoke, and filling the region with a choking smog.

The record heat, drought, and fire outbreaks for this region come during a year in which record hot global temperatures are hitting 1 degree C above 1880s averages. A year in which a monster El Nino is firing off. And a year in which Arctic sea ice extent measures are in the range of second lowest ever recorded. All these factors likely played a part in the formation of a persistent heat dome high pressure system over Eastern Europe during July and August. In the setting off of the kinds of wildfires that have now become all-too-common in a rapidly warming world.
For Europe, in general, there were numerous related impacts throughout mid-to-late summer. According to a related report from DW:
The impact of the lack of rain and high temperatures could be felt across many sectors. Agricultural production was reduced, and forests dried out and became more susceptible to insect attacks. Hydropower production decreased, rivers fell to record low levels, and inland water transport was completely shut down in some places.
By today, temperatures across Ukraine and extreme Southwestern Russia had risen to an amazing 12-14 degrees Celsius above average (21 to 25 degrees Fahrenheit hotter than normal for this time of year). It’s a ridiculous extreme temperature departure for a mid-latitude region. The scorching center of a stifling dome of hot air that extends from the Caspian Sea all the way to Poland and Italy.
(Temperatures in Russia and the Ukraine today hit 12-14 C above the already hotter than normal 1979-2000 baseline in the GFS model summary by Climate Reanalyzer.)
This record heat, drought and fire danger is expected to linger over the impacted regions for at least until Sunday. Then, a trough digging in through Eastern Ukraine is expected to shove the hot pool eastward into Russia and Kazakhstan. Setting the stage for record hot conditions running along a ridge extending from the Middle East through Russia and Siberia and on into the Arctic.
