Permafrost, wetland, wildfire and freshwater emissions could amplify climate change by up to 30%, study finds
A study reported by Mongabay says emissions from thawing permafrost, wetlands, wildfires and freshwater systems could amplify climate change by up to 30%. In the Arctic, thawing frozen ground exposes plant and animal remains to decay, releasing methane and carbon dioxide that trap heat and contribute to further warming.
A study reported by Mongabay says emissions from permafrost, wetlands, wildfires and freshwater systems could amplify climate change by up to 30%. The supplied report identifies these sources as part of climate feedbacks that may increase warming.
In the Arctic, frozen ground contains dead plants and animals that have remained locked in soils for thousands of years. As permafrost thaws, those materials begin to decay.
That decay releases methane and carbon dioxide, according to the report. Both gases trap heat from the sun and warm the planet.
The report describes a feedback loop in which rising temperatures lead to more Arctic permafrost thaw, potentially causing additional emissions and further warming. The supplied source does not provide details about the study’s authors, methods, publication venue or the separate contributions of wetlands, wildfires and freshwater systems.
THE QUESTIONS THIS EVENT LEAVES BEHIND
How much of the projected amplification is attributed to each emissions source?
What assumptions did the study make about future warming and permafrost thaw?
Which regions or communities would face the greatest consequences if the feedbacks intensify?
How might the findings change under different wildfire, wetland or freshwater conditions?
What actions could reduce the emissions described in the study?
