Are “mega-irons” on the increase? What satellite data and images show

It has ravaged California since mid-July and has already swallowed up more than 3,000 square kilometers of forests and homes: Dixie Fire is the second largest fire in the history of the American state. In Siberia, 15,000 square kilometers of forests were destroyed this summer. Yet studies show that the total number of fires on Earth has not increased for fifteen years. The areas burned on the whole planet are even tending to decrease. How to explain it?

Analysis of satellite images, as well as data collected by NASA, can explain these phenomena. With climate change, fires are changing in nature: they appear in areas that were previously relatively untouched and are increasingly violent.
