NASA news: Images from space agency show wildfires ACROSS GLOBE | Science | News

Satellite images from the space agency paint a picture of just how bad widlfires around Earth have become.

While there is no data available to suggest how much land is on fire throughout the world, in the United States alone 3.3 million acres, or 5,1256 miles, are currently ablaze.

US authorities said there are more than 100 major wildfires burning across the country currently, including three of the biggest in Californian history.

While many of the fires are wild, NASA says that the ones in Africa are likely agricultural.

A statement reads: “Using thermal bands to detect active burning areas, each red dot is a fire.

“The fires in Africa are likely agricultural, while elsewhere, the fires are likely wildfire.

“The location, widespread nature, and number of fires suggest that these fires were deliberately set to manage land.

“Farmers often use fire to return nutrients to the soil and to clear the ground of unwanted plants.

“While fire helps enhance crops and grasses for pasture, the fires also produce smoke that degrades air quality.”

Europe is largely void of wildfires by South America, much like its northern counterpart, is currently being ravaged by blazes.

Chile and Brazil are experiencing most of the fires, and NASA says they are a mixture of wild and agricultural blazes.

A study conducted by Montana State University found that: “Besides low humidity, high winds and extreme temperatures — some of the same factors contributing to fires raging across the United States — central Chile is experiencing a mega drought and large portions of its diverse native forests have been converted to more flammable tree plantations.

NASA added: “Fires are also commonly used during Brazil’s dry period to deforest land and clear it for raising cattle or other agricultural or extraction purposes.

“The problem with these fires is that they grow out of control quickly due to climate issues. Hot, dry conditions coupled with wind drive fires far from their original intended burn area.”
