A new environmental study has managed to uncover evidence which links human-influenced global warming to the melting of the West Antarctic Ice Sheet.
In recent decades the ice has started to disappear at an accelerated pace in West Antarctica, and the phenomenon will likely continue in the following years. Many researchers argued that the melting speed is affected by the presence of warm ocean water, which is influenced by the winds which are present in the region and able to modify ocean conditions around glaciers.
The report, which was published a few days ago, argues that human activities have caused a long-term chance related to the winds. If nothing is done to mitigate the negative impact, the level of the sea could increase by tens of centimeters in less than a decade according to previous papers.
New evidence links human activity to climate change in Antarctica
To learn more about the phenomena the team employed the help of satellite observations and climate model simulations which offered valuable data about how the winds present in the West Antarctica region have changed due to the increasing levels of greenhouse gases. It seems that human-induced climate change plays an essential role in the changes which affected wind patterns, and which led to warmer ocean conditions.
According to the primary author of the study, the impact of climate change is more complicated than it may seem. The study establishes the first definite link between human activities and decreasing levels of ice with the latter being exacerbated by the former. It is also mentioned that the high levels of greenhouse gas emissions could lead to more consequences in the future as wind patterns continue to change, and the temperature of the oceans will grow.
By reducing these emissions, such events could be avoided, but significant changes are needed to complete the goal. The results solve one of the most enduring environmental puzzles and confirm theories mentioned in previous works. The study was published in a scientific journal.
Karen and her husband live on a plot of land in British Columbia. They aim to grow and raise a significant part of their food by maintaining a vegetable garden, keeping a flock of backyard chickens and foraging. They are also currently planning a move to a small cabin they hand built. Karen’s academic background in nutrition made her care deeply about real food and seek ways to obtain it. Thus sprung Anna’s interest in backyard gardening, chicken and goat keeping, recycling and self-sufficiency.
