Question

.How Arctic-carbon is increasing? State the causes? Also, as an individual how can we stop these changes?

Answer 1

Since the 1960s, the differences between summer and winter CO2 concentrations at Arctic latitudes have grown significantly; in some areas, the fluctuations have increased by as much as 25%. Scientists haven't yet discovered why this is happening. A recent computer simulation links long-term warming in the Arctic to the widespread plant growth that has occurred in recent years. A large portion of the Arctic has been greening more since the early 1980s, according to satellite observations that were used to calibrate the simulation.

 

Major causes of high carbon concentration in Artic:

 

Evapotranspiration and river runoff into the Arctic Ocean have risen along with precipitation and temperature. Increased river discharge causes the Arctic Ocean to receive more nutrients and organic carbon as well as aerating the ocean water.

 

In frozen Arctic soil that is too cold for decomposition, organic carbon from plant and animal remains has been preserved for thousands of years. Permafrost, a type of Arctic soil, contains more carbon than the planet's atmosphere at this time.

 

The Arctic has seen the fastest rate of climatic change of any place on Earth. As a result of these changes, the Arctic's carbon budget will undoubtedly change as flora shifts, soils warm, fires become more common, and wetlands change as permafrost thaws.

 

Likelihood that Arctic atmospheric emissions comparable to those from fossil fuels will be produced through decomposition as well as fires rises as the frozen tundra continues to thaw. There will be a significant difference in the amount of greenhouse warming these emissions produce depending on whether they are carbon dioxide or methane.

 

Steps that can be followed to reduce increasing carbon concentration in Artic region:

 

Through obligatory fuel quality standards for on- and off-road use, clean fuel supply is ensured. Encourage the use of cleaner transportation options and impose pollution fees. Encourage the shipping industry to implement pollution control measures voluntarily.

 

Methane emissions could be drastically reduced to stop climate change, preserve the summer sea ice in the Arctic, and safeguard the many creatures that live on sea ice.

 

Beginning with quick reductions in the short-lived climatic pollutants—black carbon, methane, tropospheric ozone, and hydrofluorocarbons—fast mitigation at scale can still delay future Arctic warming. The Arctic warming rate can be slowed down by up to two thirds by immediately reducing emissions of these transient pollutants.

 

 

 

Immediately cutting methane emissions along with CO2 is our best chance at preserving Arctic summer sea ice within our lifetimes and for future generations. Reducing current methane emissions represents a huge opportunity to help slow down global warming.
