Climate change is quicker and stronger in the Arctic than in most of the. The Polar zone is now getting more warmer at a rate of twice the earth’s average. In Polar zone, it gets warmer quicker than the the world. As the Polar zone loses snow and ice, rock and water absorb more and more of the sun’s energy, making it ever warmer. This is called the albedo effect.
Global warming is an issue we have all been made very aware of. However, although it appears to be a very straightforward process, numerous studies conducted on the problem have yielded varied results and conflicting evidence. This means there is little certainty over what is actually happening, the reasons for it, and the implications. On a very basic level, the problem is changes in the climate, which appear to be causing ice in the Polar Regions to melt. This in turn is causing many changes including a rise in sea levels, and damage to arctic environments, which is also greatly affecting wildlife
Nevertheless, there is a general consensus that human influences are contributing significantly. As the Intergovernmental Panel on Climate Change concluded in their 1995 scientific assessment: ‘the balance of evidence suggests a discernable human influence on global climate’. This human influence is mainly in the form of detrimental greenhouse gases and the destruction of forests, which absorb damaging carbon dioxide.
In fact the melting of the Polar Regions is at the moment most critical for the wildlife that inhabit them. These regions are home to a surprising range of perfectly evolved animals including polar bears, seals, walruses, penguins, caribou, and a great array of arctic sea life. These creatures rely on the ice cover and seasonal changes in environment to survive.
The polar bear, for example, is most active during winter and spring, as this is when ithe ice cover is at its peak. But with warmer weather, the colder season is receding – the ‘spring break-up’ for example, now come 3 weeks earlier than it used to. This is a significant reduction in the time that the bears have to stock up on – they often go many months without feeding, a pregnant mother, for example, can fast for up to 8 months. But the longer the warmer season lasts, the longer the bears have to last without food. The effects are evident through the bears’ loss of weight and reduced numbers of cubs.
