Why in news
The 2024 Arctic Report Card was released, highlighting significant environmental changes in the Arctic due to rising temperatures.
It was prepared by 97 scientists from 11 countries and discusses the rapid transformation of the Arctic and its global consequences.
What the Report Says
The Arctic is warming faster than any other region, with shorter snow seasons and reduced sea ice, causing disruptions to ecosystems and human life.
Animals like seals and caribou are affected by warming, and indigenous communities face challenges to their way of life due to changing environments.
The report points to unusual weather patterns, such as more snow in some regions and extreme heat in others, making planning and adaptation difficult.
How Arctic Tundra Becomes a Carbon Source
The Arctic tundra, traditionally a carbon sink, is releasing stored carbon due to thawing permafrost.
As permafrost thaws, microbes decompose stored carbon into carbon dioxide and methane, which are potent greenhouse gases.
Wildfires in the Arctic are also increasing, contributing to more carbon emissions.
This shift from a carbon sink to a carbon source accelerates global warming and adds urgency to reducing human emissions.
