The Kostanai Region declared a state of emergency on Sept. 4 after forest fires burned a record 43,000 hectares (the size of Сarribean Barbados island) and forced an evacuation of 1,841 people.

Anchorage saw temperatures spike above 60 degrees every day in June for the first time in recorded history. The city also experienced near record low precipitation: Only 1/10 of an inch of rain fell the entire month.

“It’s been hot, it’s been dry, and it’s been windy. And those winds gusts of 20 miles per hour, it’s kind of funneled through the Andreafsky River drainage,” said Beth Ipsen. Federal entities sent in more firefighters this week, and some residents are thinking about preparing their go-bags.

Fires are already erupting in Siberia this spring, sending billowing smoke into the western United States. One of the regions with the largest number of extinguished forest fires was in Omsk Oblast. Videos from the Siberian Times showed wildfires raging across the Omsk and Tyumen oblasts in Western Siberia, while satellite data showed several fires across the landscape beginning in the first half of April.

Delhi’s Ghazipur landfill site set ablaze due to the release of methane gas, as there many dry leaves on the site at that time and also as the temperature in the city is very high, the leaves caught fire from the gas and set the entire landfill site ablaze. The entire area was covered with smoke.
