Did you know? The Arctic tundra has changed. It used to absorb carbon, but now it releases carbon instead.
The Arctic tundra, once covered by ice and snow, has changed. It used to absorb carbon but now releases more carbon than it absorbs. This shift is believed to be caused by the increasing frequency of wildfires, which raise surface temperatures.
According to a report by the National Oceanic and Atmospheric Administration (NOAA), the Arctic tundra is undergoing significant changes. The frequency of wildfires has turned what was once a major carbon sink into a net carbon emitter. The NOAA also revealed that this year’s surface air temperature in the Arctic ranks as the second highest since records began in 1900.
Currently, the Arctic tundra faces the combined impacts of global warming and increasing wildfires, which affect both aspects of the region. While global warming has boosted plant growth, helping to remove carbon dioxide from the atmosphere, it has also raised surface temperatures, causing the permafrost to melt. The carbon trapped in the permafrost is then released into the atmosphere as carbon dioxide and methane.
The extreme changes are largely caused by human activities, including wildfires and increased carbon dioxide emissions. If we continue to wait for the situation to worsen without taking action, everyone will inevitably face more severe natural disasters in the future, which will be difficult to manage.
