The soil has two layers, the active layer and the permafrost itself. The the active layer is what we are using for building and living on. The permafrost is what keeps the ground solid and without the permafrost, everything on the active layer are sinking into the now softer soil]]> 2019-04-11 18:18:22 UTC https://padlet.com/ssantos6580/71ochfn1remc/wish/350914599 Focus Questions ssantos6580 https://padlet.com/ssantos6580/71ochfn1remc/wish/351263039 evidence

This thawing revitalizes the bacteria lying dormant in the soil to release methane gas, a greenhouse gas, further heating the planet and intensifying the cycle.]]> 2019-04-12 18:13:51 UTC https://padlet.com/ssantos6580/71ochfn1remc/wish/351269239 ahernandez1926 https://padlet.com/ssantos6580/71ochfn1remc/wish/351274505 2019-04-12 18:25:51 UTC https://padlet.com/ssantos6580/71ochfn1remc/wish/351274505 Why we need to do something ssantos6580 https://padlet.com/ssantos6580/71ochfn1remc/wish/351751846 The thawing of the permafrost could lead to sinkholes becoming more frequent and the compromised stability of the ground could lead to negative consequences with the structural integrity of buildings]]> 2019-04-15 17:50:11 UTC https://padlet.com/ssantos6580/71ochfn1remc/wish/351751846 Specific examples ahernandez1926 https://padlet.com/ssantos6580/71ochfn1remc/wish/351752967 Russia and Alaska are facing the issue of melting permafrost. The permafrost regions occupy about 25% of the Northern Hemisphere's terrestrial surface, and almost 65% of that of Russia. Warming, thawing, and degradation of permafrost have been observed in many locations in recent decades and are likely to accelerate in the future as a result of climatic change]]> 2019-04-15 17:52:57 UTC https://padlet.com/ssantos6580/71ochfn1remc/wish/351752967 Methane? ssantos6580 https://padlet.com/ssantos6580/71ochfn1remc/wish/351760019 Because of the permafrost melting, bacteria that have been frozen since the ice age are now warming up and becoming active. Because these bacteria are becoming active, they are producing natural methane that being released into the atmosphere. Methane is a MAJOR greenhouse gas that is creating more warmth that melts more permafrost. ]]> 2019-04-15 18:08:52 UTC https://padlet.com/ssantos6580/71ochfn1remc/wish/351760019 Human impact? ssantos6580 https://padlet.com/ssantos6580/71ochfn1remc/wish/351761399 The ground in affected areas would lose ground as well as structures would begin to sink into the ground]]> 2019-04-15 18:11:56 UTC https://padlet.com/ssantos6580/71ochfn1remc/wish/351761399
