Permafrost is soil that has been frozen for at least two years. It occupies about 15% of the land area in the Northern Hemisphere and contains a large amount of organic matter. When the permafrost thaws, this organic matter is released into the atmosphere, where it can decompose and produce methane.
Methane is a greenhouse gas that is 25 times stronger than carbon dioxide. It is also a known carcinogen. Methane exposure has been linked to lung cancer, as well as other health problems such as breathing problems and headaches.
A recent study published in the journal Nature Climate Change found that the amount of methane released from permafrost could increase by 50% by the end of the century. This can have serious consequences for human health, as it can lead to an increase in lung cancer and other health problems.
The study authors say more research is needed to understand the full impact of melting permafrost on human health. They also say it is important to take steps to reduce greenhouse gas emissions to slow the rate of permafrost melting.
Expert opinions:
"This study is a wake-up call about the dangers of climate change," said Dr. Michael Mann, a climate scientist at Pennsylvania State University. "Methane emissions from permafrost can have devastating effects on human health."
"We need to take action now to reduce greenhouse gas emissions and slow the rate of permafrost melting," said Dr. Jennifer Marlon, a climate scientist at the University of Maryland. "The future of our planet depends on it."
