The Arctic climate time bomb is becoming one of the most important climate warnings of our time. Scientists have discovered that Arctic river deltas may contain about 63.4 billion tons of carbon locked inside frozen soils. The finding changes how researchers view the hidden risks beneath Earth’s northern ice.
For thousands of years, Arctic permafrost acted like a natural freezer. It preserved ancient plant material that never fully decomposed. However, rising temperatures are slowly weakening this frozen storage system. Once the ground warms, microbes can break down the trapped material and release greenhouse gases.
