Climate Change Transforms Tundra

The recent report on climate change indicates that tundra regions, traditionally known as carbon sinks due to the accumulation of organic carbon in frozen soils, are transitioning into carbon sources as a result of global warming. This shift is driven by increased air and soil temperatures, which enhance metabolic activities in plants and microbes, leading to a significant rise in carbon release during the growing season. An international team of scientists conducted experiments across multiple tundra sites over 25 years, confirming that the rate of warming in these areas is substantially higher than the global average. This transformation could have profound implications for future climate predictions and underscores the need for detailed inclusion of tundra carbon
