A heat map of the planet showing methane emissions from wetlands from 1980 to 2021. Greenhouse gas emissions from wetlands of concern consist primarily of methane and nitrous oxide emissions. Wetlands are the largest natural source of atmospheric methane in the world, and are therefore a major area of concern with respect to climate change.
Data published in March 2023 in Nature Climate Change shows that annual wetland emissions over the past two decades were about 500,000 tonnes per year higher than what scientists had projected ...

On this map, a shift of 1 indicates that at the end of the century, the region had fully moved into a completely different Holdridge zone type from where it had been historically. The extent of the shifts will be dependent on the severity of the climate change scenario followed. [8]
Wetlands play a crucial and multifaceted role in mitigating climate change through their natural processes and functions. [10] They capture carbon from the air when plants grow and trap sediment from water. This carbon gets stored in plants, leaves, soil, and mud, sometimes for thousands of years. [11]
The last time the USDA changed the Hardiness Zone map was 2012. Although the changes are subtle, it does indicate that we are experencing warmer temps. ... Climate change and plant hardiness zones.
In late 2020, a quarter of the wetland was destroyed by an unprecedented fire attributed to climate change. An area estimated of about 19,890 square kilometres (7,681 sq mi) was razed by the fire, killing millions of vertebrates. [26] Experts say 2020 was the most active year on record for wildfires. [27]
Erosion from heavy storms, climate change, and human interference with the environment contribute to erosion in South Louisiana. [5] The Gulf of Mexico brings heavy rains and hurricanes to this region. This loosens the sediments in the marshes, and along the Mississippi River, allowing them to be carried away by the water. Human interference ...
