Montana: Dominic Point Wildfire
First reported July 25, the Dominic Point fire in Montana, and the International Space Station took this picture just an hour after that first report, when the plume of smoke already stretched for five miles. A combination of high heat, low humidity and abundant deadwood have helped this fire burn nearly 900 acres of Bitterroot National Forest in far western Montana, about 12 miles northeast of Hamilton, and roughly that far from the Idaho border. Global warming is making those conditions that set the stage for large wildfires more common. See 4 ways global warming increases fire risk.
California: Bull Wildfire
The Bull Fire has burned over 16,000 acres of Sequoia National Forest, destroyed several homes and forced the evacuations of many people since starting July 26. To help orient the viewer, here's how NASA describes this image: "The Sequoia National Forest is at the southern end of the Sierra Nevada range. In this image, the mountains are covered in deep green forest. The snow-capped peaks north of the fire are dingy brown and partially obscured by smoke. To the west of the mountains is San Joaquin Valley, the southern half of the Central Valley. The valley is checkered with green farm fields and dotted with gray cities and towns. In the rain shadow of the Sierra Nevada, the land to the east is mostly desert brown and tan. This area is Death Valley National Park, which is part of the Mojave Desert. The Nevada state line cuts across the upper right corner of the image."
Canada: Saskatchewan Fires
In the far north of Canada's remote Saskatchewan province, many wildfires are burning. To date, nearly 3.5 million acres of forest has burned in Saskatchewan this fire season, more than five times as much as the 25-year average for the same annual period. This image was captured July 13.
China: Farm Fires
In Eastern China, many fires were burning in early July when NASA's Terra satellite captured this image. Most likely agricultural fires set on purpose south of Beijing, they nonetheless contribute to air pollution that has made China's air quality notoriously bad.
Russia: Moscow Peat Bog Fires
Outside Moscow, multiple peat bog fires have been burning throughout July. NASA caught this satellite image July 28. The peat bog fires are a consequence of record-setting heat, which has been blamed for thousands of deaths (including drownings from people attempting to escape the heat). The fires contribute to unhealthy air pollution that the heat already exacerbates.
Russia: Eastern Siberian Wildfires
On the other side of the continent, drought and heat also contributed to extreme wildfires, the smoke from which extended into the Bering Sea (bottom right). Here's how NASA describes the image: "This image shows the region north of the Kamchatka Peninsula. The largest collection of fires is clustered around a river that feeds into the Penzhinskaya Guba, part of the Sea of Okhotsk. Smaller clusters of fires also burn in the northwest, northeast, and south. Most of the fires send their smoke toward the northeast, but east of the burning fires, winds carry the smoke toward the southeast. Off the coast, the smoke plume is thick enough to completely hide parts of the Bering Sea." The red outlined areas indicate areas of extreme ground-level heat, most likely the individual fires causing smoke.
Russia: Volga River Wildfires
Another set of fires in Western Russia, these in the forests along the Volga River, burned hot in early July. As in the last image, the red outlines indicate unusually warm ground-level temperatures, a hallmark of fire. This image was captured July 2.
