The Arctic Ice Meltdown
The Arctic is one of the regions on earth that is highly susceptible to climate change. Since the 1980s, the Arctic has been experiencing an ongoing and dramatic ice loss, significantly altering the Arctic landscape. This ice loss is believed to be due to the warming climate caused by the increase in global greenhouse gas emissions that trap heat in the earth’s atmosphere.
The Arctic sea ice melt is reducing more quickly than previously anticipated, and it is likely that the Arctic could be ice-free in the summer months in 15 years. When the Arctic ice disappears during the summer months, it has profound implications, such as the fragile arctic ecosystem being altered. The melting ice has implications for marine mammals that inhabit the Arctic and depend on the ice for survival for example the polar bear, Arctic fox, walrus and seal.
Impact on the Ecosystem
The effects of the Arctic meltdown go beyond the wildlife and extend to the overall ecosystem. The Arctic is home to several indigenous communities, including the Inuit, who profoundly rely on the Arctic ecosystem for their culture and livelihoods. There is a danger that these communities will be adversely affected by the loss of the Arctic ice, which is their source of food and life.
As the Arctic sea ice melts, it exposes more ocean water to solar radiation, leading to an increase in ocean temperature. This can also lead to altered ocean currents, erosion, and changes in sea levels, which can impact the world’s coasts and its populations.
The Cryospheric Feedback Loop
The Arctic ice melt has also set up a potentially dangerous feedback loop called the Cryospheric Feedback Loop. As the Arctic ice melts, the heat absorbed by the ocean increases, and the ocean temperature rises. This rise exacerbates the trend of ice melting and releases more carbon into the atmosphere, leading to an acceleration of global warming.
The loss of sea ice alters the reflectivity of the Arctic region, which was previously white and reflective, to being dark and absorptive. This shift causes optimistic sunlight absorption, resulting in the Arctic warming up more than surfaces covered in snow and ice would have.
The Arctic meltdown is a warning sign that climate change is real and already having a significant impact on the environment. The melting of the Arctic sea ice shows the heat that has been trapped, resulting in an increase in global greenhouse gas emissions, currently trapped in the Earth’s atmosphere. The impact of climate change extends beyond the Arctic, with coastal areas throughout the world being affected by the rising sea level. It is time not only for the Arctic community, but for the world, to unite and act together to combat climate change and save our planet.
