​​ **__ Permafrost and Climate Change __**

** __What is Permafrost?__ ** Permafrost is a thermal condition - its formation, persistence or disappearance are highly dependent on climate. The change of the shape of permafrost changes due to the change in temperature. Also another thing that could change the form and size of a permafrost is natural occurances such as: the change in the temperature in the air or perciptitation, clearing of vegitation which causes surface disturbances, forest fires, migration fo river channels, etc. All of these occurances cause for permafrost to break, shirink or change their size and shape.

Take a look at how it works!....

What is Climate Change? __**Definition: Climate Change is any change in in global temperatures and precipitation due to natural variablity or to human activity.

Relationship Between Permafrost and Climate Change.. **__You might be asking yourself what do these two things have in common? Well, permafrost and climate change work together in many ways. Shockingly, the affect that climate change has on permafrost in tremendous. According to the General Circulation the doubling of the amount of carbondioxide, which is caused by anthropogenic sources, the level of temperature will rise several degrees in the Artic. The relationship between permafrost and climate change is the reality- that the earth temperature isnt the same as before, it is getting warmer. If the earths temperature is increasing then that causes the permafrost thats left to melt. As the permafrost melts it produces gases that affect our environment.


 * The image below should give you a good idea of the damage in infrastructure due to Permafrost thawing. This should also help u realize that this is a BIG issue!



< ABOUT THIS IMAGE:

~ Infrastructure risk by 2050 due to Permafrost thawing.

~ This image was calculated using the "Hadley Climat Model with the moderate B2 emissions scenario".

~ Places with stable Permafrost are also shown here, which are not likely to change.

~ This also indicates high potential for coastal erosions. (areas in the moderate and high risk category)



Other Places That Are Affected By Permafrost and Climate Change __**
 * __

The artic plants are feeling the change in the climate and its affecting it alot. On one hand the warmer tempertures and the increasing amout of carbon dioxide is causing a "greener affect" which is expanding the range of the vegetation. And on the other hand it is causing the underground permafrost to melt which is causing the surface water to drain and the soild to become dryer. Due to this change it causes stress and drought in the plants.
