NASA is monitoring fires through the Earth Observation System Data and Information System (EOSDIS), where smoke and burning, all of which are difficult to escape the eyes of satellites above the earth. Recently NASA released a new satellite image showing the terrible fires that occur around the world.
From this shocking map, you can see that the whole earth is burning. From Canada to Australia, from South America to sub-Saharan Africa, the raging fire seems to reflect the entire planet. While this picture is frightening, most of the red areas are actually some routine events.
NASA's map is based on fire heat detected by satellites, with red indicating areas with high measurements. Some of the regular burning, such as the burning of agricultural activities such as straw, is also recorded, so the fires you see in sub-Saharan Africa and madagascar actually occur year after year, reflecting the local slash-and-burn agricultural life. Farmers burn the straw of their crops, which frees up land and replenishes fertilizer to the soil, and of course produces smoke that is harmful to the human body. The red dots you see in Brazil and Indonesia on the map are also caused by these agricultural activities.
But in California in the west and British Columbia in Canada, these red dots are real forests burning — extreme weather makes forests easier to burn and wildfires due to global warming, dry weather, high winds and heat. Chile and Germany have also recently experienced large-scale forest fires, and Sweden has even had more than 50 forest fires, burning all over the country, and it is necessary to ask its European neighbors to send firefighting forces to help extinguish the fire.
While the scary red dots in many places on this map don't require much worry, the unusual forest fires in some areas caused by global warming caused by human greenhouse gas emissions must be of great concern to us.
Australia has been extremely dry and hot this year, and the risk of fires is increasing and the time will be extended. China doesn't seem to be greatly affected, but if this map shows a few years ago, we also burned straw on a large scale and slashed and burned. It is an indisputable fact that the global average temperature is rising, and I hope that we have the wisdom, technology and courage to solve the increasing greenhouse gas emission problems since the Industrial Revolution, so that our earth home is no longer harmed, and our sky will always be beautiful and sunny, warm and warm.
