wetlands and climate change

The relationship between wetlands and climate change is complex. Wetlands are essential to life on earth, supporting more than 125,500 freshwater-dependent species. Driving these changes is the fact that most montane wetlands are located either in snow-dominated watersheds or mixed-rain-and-snow watersheds where snowmelt is a key water … There is huge potential to create more of these valuable coastal wetlands as a crucial part of the UK’s contribution to tackling climate change. Wetlands have the ability to not only help humans mitigate the impacts of climate change (through carbon sequestration), but also to adapt to extreme weather events associated with climate change. Wetlands can also play an important role in our responses to a changing climate, through capturing and storing carbon to reduce greenhouse gas emissions, and through moderating the impact of hazards such as flooding, storm surge and sea level rise. Drainage and degradation of wetlands can release significant amounts of this stored carbon back into the atmosphere in the form of methane and reduce the ability of wetlands to sequester additional … Scientists estimate that wetlands store up to one-third of terrestrial carbon! They are also known as water-related ecosystems because they are the source of most of the world’s fresh water; they regulate water flows thus reduce floods and droughts. Drought and Wildfires. Despite the pivotal role of wetlands in countering climate change, supporting biodiversity and mitigating disaster risk, the 2018 Global Wetland Outlook, published by the Ramsar Convention on Wetlands, found that wetlands remain “dangerously undervalued” by policy- and decision-makers in national plans. Dams. As a frontier-type ecosystem, wetlands are particularly vulnerable to climatic variation and extreme events. This is just one of the reasons that wetland species like amphibians, migratory birds and corals are among the first and hardest hit by climate change. Wetlands have very specific water elevation tolerances. Some wetlands, including coral reefs, mangroves, swamps and those in high latitude and alpine zones, are especially at risk. Flooding is known only for the ruin it brings to homes and livelihoods, but targeted flooding, to create or restore floodplain wetlands, is part of the solution to climate change. The amounts of money given to support efforts to tackle climate change and nature loss range from £5,000 to millions of pounds, and the focus of the funding is as broad. Wetlands are globally important carbon sinks, storing vast amounts of carbon and thereby helping to mitigate climate change. That means that wetlands have the ability to store excess carbon (via photosynthesis) from the atmosphere – one of the primary components of greenhouse gases and a driver of climate change. Wetland methane cycling increased during a rapid global warming event 56 million years ago and could foreshadow changes the methane cycle will experience in … Climate change. They provide globally significant social, economic, and environmental benefits. Wetlands perform two important functions in relation to climate change. We find that climate change-induced increases in boreal wetland extent and temperature-driven increases in tropical CH4 emissions will dominate anthropogenic CH4 … Wetland methane cycling increased during a rapid global warming event 56 million years ago and could foreshadow changes the methane cycle will experience in the future, according to new research led by the University of Bristol.
