PER2: video jsem nevidel, ale podporujou to teda nejaky solid studie, ze by slo o akrtickej metan? zatim to bylo minimum, hlavni zdroje ekosystem a ziskavani fosilnich paliv, a hlabne tropicky oblasti.
Methane Emissions Continue to Rise

Across the study years, wetlands contributed 30 percent of global methane emissions, with oil, gas, and coal activities accounting for 20 percent. Agriculture, including enteric fermentation and manure management, made up 24 percent of emissions, and landfills comprised 11 percent. Sixty-four percent of emissions came from tropical regions of South America, Asia, and Africa, with temperate regions accounting for 32 percent and the Arctic contributing 4 percent.

High-latitude ecosystems are particularly vulnerable to climate change. Large amounts of carbon are stored in frozen soils (permafrost) and in forest vegetation in the Arctic. As it thaws, water-logged soil becomes an ideal environment for methane production. “However, we have yet to detect abnormal methane emissions in higher-latitude regions,” said Poulter, “despite thawing permafrost and record-breaking air temperatures year-after-year.”
