Is Global Warming A Positive Feedback Loop

Climate change has become a widely talked topic in the recent years and its effects are becoming increasingly publicized. One of the major issues associated with climate change is Global Warming, which is an effect of the unnaturally high levels of carbon dioxide that has been pumped into the atmosphere. It is amounting to a continuous temperature rise in global climates leading to environmental damage. One of the key questions being debated is whether or not Global Warming is a positive feedback loop.

A positive feedback loop is an environmental process in which the effects of the loop snowball and create an accelerated effect. In regards to Global Warming, potential positive feedback loops could include the melting of polar ice caps, the burning of forests and the release of permafrost carbon. All of these effects are linked to Global Warming as the temperatures become increasingly uncomfortable for the Earth’s ecosystems, which can then cause further increases in temperatures.

One of the most talked about topics in relation to Global Warming is the melting of polar ice caps. As extreme temperatures rise, glaciologists are noticing that ice caps are releasing masses of freshwater into the ocean. This decreases the salinity of the ocean which could change the ocean current, potentially leading to the trapping of increased amounts of heat in certain areas and an overall acceleration of global warming.1

The second effect often linked with Global Warming is the burning of forests. Forests account for a significant measure of the global carbon sink – meaning that they absorb carbon dioxide. As temperatures rise, this process is also accelerated, and tree’s are not able to release the captured carbon dioxide. This leads to a higher concentration in the atmosphere creating a strong potential acceleration of global warming.2

The release of permafrost carbon is the last notable factor of the Global Warming debate. Permafrost is land that has been frozen for several thousand years. As temperatures rise, these areas begin to thaw, releasing large amounts of carbon dioxide, methane, and nitrous oxide – all of which create extreme temperature rises in their own right. This process is believed to accelerate the warming effects of Global Warming.3

Though it’s not to say that Global Warming can not benefit us in any way. It is likely that, in certain parts of the world, extreme temperatures will present themselves as a positive thing, opening up regions of the world previously abolished by permafrost to human capabilities, potentially increasing agricultural activity and providing new opportunities for trade and commerce. Research has also been conducted on the benefits of increased populations of bees in areas where temperatures are higher, potentially meaning food security for some regions of the world.4

Nevertheless, when all factors are taken into consideration, the extreme rise in temperatures due to Global Warming could potentially lead to more disadvantages than advantages. The destruction of natural habitats, an increase in extreme weather events and potentially extreme water shortages are all effects that could be experienced if temperatures rise too quickly. Firstly, habitats will be destroyed as animals and plants are not able to adapt to extreme changes quickly enough, leading to a denigration of biodiversity.5

Climate change matters – it is bigger than any political agenda or personal opinion. Taking into consideration the potential destruction to our planet, the increase in global temperatures could lead to an accelerated feedback loop that could present very detrimental effects. It is of paramount importance that we as humans consider this debate and the implications of Global Warming, working towards sustainable solutions to reduce our negative impacts.
