Wildfires

Levels of carbon dioxide (CO2) in the atmosphere are accelerating, even though emissions from fossil fuel burning have remained virtually the same over the past few years.

One of the reason behind this is accelerating emissions from wildfires as temperatures are rising.

Wildfires in Nevada caused CO2 to reach levels as high as 742 ppm on July 12, 2017 (green circle image on the right).

Global warming is greatly increasing the chance for what was previously seen as an extreme weather event to occur, such as a combination of droughts and storms. Heat waves and droughts can cause much vegetation to be in a bad condition, while high temperatures can come with strong winds, storms and lightning.

Wildfires cause a range of emissions, including CO2, soot, methane and carbon monoxide (CO). In Nevada, CO levels were as high as 30.43 ppm (green circle image right).
 

Above satellite image below shows the smoke plumes and the charred area. The google maps image below further shows where the fires were burning.


At the moment, wildfires are hitting many places around the world.

Wildfires caused carbon dioxide to reach levels as high as 746 ppm on July 11, 2017 (green circle on image on the right).

Carbon monoxide levels in the area were as high as 20.96 ppm on July 10, 2017.

The satellite image shows wildfires in Kazakhstan on July 9, 2017.

On July 16, 2017, CO₂ reached levels as high as 830 ppm in North America at the location marked by the green circle on the image below. Note that fires are burning at multiple locations.


The image below shows the location (red marker) where the fires burned in Canada.


That same day, July 16, 2017, CO₂ reached levels as high as 873 ppm in Mongolia, as shown by the image on the right.

The image also shows further fires burning in Siberia.

Carbon monoxide levels were as high as 37.19 ppm where the fires burned in Mongolia on July 16, 2017, as shown by the image below.


The image below shows the location (red marker) where the fires burned in Mongolia. The image also shows Lake Baikal across the border with Russia.


CO₂ reached levels as high as 884 ppm in Montana on July 23, 2017 (green circle on image below).


Meanwhile, temperatures keep rising. Surface temperature as high as 53.1°C or 127.5°F were forecast in Iran for July 11, 2017, at the location marked by the green circle on the image below.


At 1000 mb (image below), temperatures in Iran were forecast to be slightly lower, i.e. as high as 51.9°C or 125.3°F at the location marked by the at green circle, but note the difference in color, especially over Greenland, the Himalayas and the Tibetan Plateau.


The situation is dire and calls for comprehensive and effective action as described at the Climate Plan.
