Permafrost Research Papers Samples For Students

Introduction

In the recent past, many scientists have provided evidence on how global warming that result from greenhouse gases may adversely affect the arctic regions (including tundra biome). These scientists argue that the excess abundant of greenhouse gases will cause global warming of the earth's climate in the near future. This global rise in temperature is more likely to damage the Antarctic and Arctic biome that than all other biome. This is because global warming is expected to shorten arctic tundra's winters and melt snow that covers permafrost. As a result of this, there will be flooding in many coastal areas. ...

Introduction

Climate change stands to be one of the major challenges of our modern time and puts a considerable amount of pressure and stress on our planet as well as on our society. Such a problem, if faced by humanity is one of the worst case scenarios imaginable, aside the asteroid hit or a super volcano eruption; major climate change can result in risen worldwide sea level leading to destructive floods, shifted climate zones with food production being threatened. Such climate change impacts are global in scale and might eventually lead to a total human extinction.
Every time the causes of climate change ...

Disturbing trends in the climatic condition of the Arctic led to scientists researching this area. Upon close scrutiny the fascinating greening of the Arctic has been observed. From the space, using Normalized Difference Vegetation Index (NDVI), which is an index of vegetation greenness, the circumpolar changes in the tundra vegetation are observed. The NDVI records of the last 29 years were gathered and the Maximum NDVI was derived. According to studies the MaxNDVI was usually observed in August due to many factors such as CO2 fluxes, above-ground biomass, total eco-system production etc. Many other biophysical properties also cause the ...
