Arctic warming will lead to global warming accelerate climate change

There has been a tremendous rise in Arctic permafrost. Due to the melting of land snow and sea ice consistently, high solar absorptions are caused, and this process will soon lead to an acceleration in the process of climate change that we have been facing currently. This will also be severely impacting the world economy which could lead to multi-trillion losses.

Recently a team of researchers released a new paper in a popular journal named Nature Communications where they revealed how these factors, when combined, have the chance of impacting the Global Economy by approximately $70 trillion. Many nations have announced their decision to cut carbon emission that amounts to 5% of their total Gross Development Production or GDP.

According to the Intergovernmental Panel on Climate Change or IPCC Paris Agreement target, nations agreed to limit the rise in global temperature to 1.5 degree Celsius. If this comes into force, the other impact will drop to $25 trillion which is 4% of the likely scenario. Here, the primary driver is to emit permafrost carbon.

The interdisciplinary research team has stated that they are hoping that these estimates would result in providing a better understanding of several socio-economic risks that such climate changes are causing or would result in the future.

Until now several researchers have explored different simulations of several physical models where they tried to qualify Permafrost Carbon Feedback strength or PCF. It is a process which gets driven when carbon releases in an additional amount. Then there exists Surface Albedo Feedback of SAF which is operated when extra solar energy gets absorbed in earth’s surface since land snow and ice sea cover start declining. This, in turn, exposes darker ocean and land.

Several studies related to climate policy conducted in the past have implied on zero PSF and a constant SAF. However, several computer models and recent feedbacks have stated that permafrost process is stronger one of the two and a non-linear process.
