Essays on Circumpolar

1. Introduction Global warming consequences have been mainly focused on the impacts they have and will in the future have on the global human population. The less focus is on the impact on the animal and plant species that are even more vulnerable, since they cannot adapt to quick changes as humans can. They are not the main culprit for the climate changes and yet they will suffer the most. One of the animal species that is being threatened by the global climate change are also polar bears that inhabit the polar region. They are playing an important role ...

Introduction

For the past 30 years overweight and obesity among Australians has been on a gradual increase, with 60% of adults categorized as overweight and more than 25% obese (National Health and Medical Research Council, 2013). The obese are perceived to be personally responsible for the cause of their own state. Changing the negative attitudes towards obese people, while trying to instill a view of empathy, has been somewhat unsuccessful (Gapinski, Schwartz, & Brownell, 2003; Teachman et al., 2003). This negative attitude encourages stereotypes that the obese and overweight are unmotivated and lazy, as well as many other negative characteristics (Persky & ...

Introduction

Polar bears are a range of bears from the family Ursidae and genus Ursus that natively lie within the boundaries of the Arctic Circle which well includes the landmasses and surrounding seas around the Arctic Ocean . Considering the native geographical location where the polar bears reside, it can be safely assumed that these creatures live in a predominantly cold weather environment . In terms of general physical features, a male adult polar bear should weight somewhere around 770 to 1,500 lbs. ; a female adult on the other hand should be somewhere around half of this size . Polar bears are a sister specie of the ...

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 ...
