The prospect of global warming carries with it far-reaching and far-reaching implications, ranging from its negative effects on the environment and food security, to the very real possibility of increased sea levels due to melting glaciers and ice sheets. It is of critical importance to consider this danger in order to be better prepared for its effects on coastal cities and villages; and the general population.
A 2018 report from the Intergovernmental Panel on Climate Change (IPCC) reported that global sea levels could rise by up to 1 meter by the year 2100, if the cumulative emissions of greenhouse gases remain at their current levels due to human activities. This would be an alarming development as it would submerge coastal areas around the world causing vast damage and major displacement of people. Low-lying areas would suffer the most, as the already meager resources of communities would be further affected.
Glacier melt is one of the most immediate aspects of rising sea levels, and its effects have already been starkly visible in many parts of the world. The Greenland Ice Sheet, for example, is the second largest ice sheet on earth and has been contributing to sea level rise since the 1990s. Studies by the US National Snow and Ice Data Center have shown that Greenland is currently melting at an accelerating pace, and can contribute an estimated 20 cm of sea level rise if this trend continues.
Furthermore, warmer waters are less dense than cold waters, leading to further increase of sea levels. The IPCC states that oceans absorb up to 90% of the excess heat energy being generated. As the waters become warmer, the volume of the oceans expands and coastlines become increasingly vulnerable.
The sea level rise is also linked to the increasingly erratic weather patterns across the world; heavier rainfall, stronger typhoons, and more frequent and intense storms. In 2018, the costliest Atlantic hurricane season in the United States cost more than Hurricane Katrina; a further indication of the dangers presented by climate change.
In light of this alarming future, it is imperative to work on solutions to mitigate the already visible effects of global warming. Nations need to come together to limit emissions and focus on renewable energy like solar, wind, and hydro power. Adopting sustainable behaviors and lifestyles is also important, as is tree-planting and utilizing energy-efficient products. Reducing carbon footprints could have a positive impact in slowing down the process of global warming.
We must be proactive and make a lasting commitment to preserving our environment and by extension, our future. Despite being powerless in the face of a problem on a global scale, we all have the capacity to make a difference. Together, our efforts can help to stem the tide of rising ocean levels, giving future generations the chance to enjoy the full spectrum of life on this planet.
