Hello everyone, welcome to my inactive  blog, lol, I know, life happened and I will try my best to be active. 

Permafrost is not outlined by soil wetness content,  snow cover or location it's defined by temperature. Any rock or soil remaining at or below 0°C for 2 or additional years is permafrost. It will contain over 30 % ice, or much no ice in the least. It may be overlain by many meters of snow or very little or no snow.  In terms of areas, permafrost may be characterised as continuous. Discontinuous, irregular or isolated however as a result of these are descriptive terms, the boundaries separating completely different ground zones may be obscure.

###  The thawing process of permafrost</sub>

Found underneath a layer of soil, permafrost might be from 3 feet to 4,900 feet thick. It stores the carbon-based remains of plants and animals that solidified before they may break down. Scientists estimate that the world's permafrost holds 1,500 billion stacks of carbon, virtually double the quantity of carbon that's presently within the atmosphere. 


Before this, once permafrost warms and thaws, it releases greenhouse emission and methane, but they new analysis reads that mercury has been found in permafrost. because the world thermostat rises,permafrost instead of storing carbon may become significant supply of planet heating emissions.

### The warming Arctic 

Permafrost covers about pure gold of the exposed solid ground of the hemisphere concerning 9milion sq.miles. it's found at high latitudes and high altitudes. The continental shelves below Arctic Ocean that were exposed throughout the last glacial epoch, additionally contain permafrost.  However, polar and high altitude regions are some the foremost climate-sensitive places on the world.  The arctic is warming double as quick because the remainder of the world at a rate of climate change that has not been ascertained in a minimum of the last 2,000 years, according to the <sub>[National Oceanic and Atmospheric Administration.](https://www.theguardian.com/environment/2017/dec/12/arctic-permafrost-sea-ice-thaw-climate-change-report)</sub>

> In Alaska, permafrost temperatures have warm the maximum amount as 2°C within the last few decades. A recent study with every 1°C increase in temperature, 1.5million sq. miles of permafrost may well be lost through thawing.

### The harzardious effects of permafrost thawing 

The worlds largest reservoir  of mercury lies in arctic permafrost, concerning seventy nine of arctic ocean is thin and only a year recent. In 1985, 45th of the ocean ice within the arctic was thick, older ice aforementioned by Emily Osborne National Oceanic and Atmospheric Administration Arctic scientist.  On the problem at hand, scientists have uncovered another hidden threat buried within the icy region. large natural reserves of mercury, a poisonous heavy metal that in some forms an be build up in fish and alternative animals and may cause serious health issues in humans.  The layer of the frozen soil that's in danger of thawing due to temperature. 

> Scientists bore a hole in permafrost cores in 13 locations across Alaska and estimated the mercury contained in them. 



With this recent investigation knowing that mercury is taken into account by WHO as one of the highest 10 chemicals or groups of chemicals of major concern to public heakth, exposure to mercury even small amount could cause serious health related issues and may be a threat to the development of the kid in utero and early in life. It. At have poisonous effect on the nervous, biological process and immune systems.


Mercury might be an strong poison and in kids it will hurt mental health, influencing learning memory, etc ,though in grown-ups will affect discourse and muscle developments, also disrupt the immune system.


### Possible solutions for climate change

* Powering a home with renewable energy. 
* Reduction in water waste...
* Shrink your cabon profile and many more...
