MEXICO: No, it isn’t love that moves mountains. Climate change does and scientists have evidence that could prove it.
Global warming has caused erratic weathers and is responsible for rising sea levels that threaten coastal communities. Now, a new study has revealed that climate change can also alter the shape of our planet.
In a five-year study published in the journal Nature on Oct. 1, Michele Koppes, from the University of British Columbia, and colleagues compared the glaciers in Patagonia and in the Antarctic Peninsula.
They found that the glaciers moved faster and caused more erosion in warmer Patagonia compared with those in Antarctica as warmer temperature and the melting of the ice contribute to the lubrication of the glacier bed.
Koppes said that the glaciers in Patagonia erode up to a thousand times faster than in Antarctica but as Antarctica warms up and moves to temperatures over 0 degrees Celsius, glaciers now all start to move faster.
The researcher said that they have already seen ice sheets that start to move faster and become more erosive, which creates deeper valleys and pour more sediments into the oceans.
“Glacial erosion rates are expected to increase with decreasing latitude, owing to the climatic control on basal temperature and the production of meltwater, which promotes glacial sliding, erosion and sediment transfer,” Koppes and colleagues wrote in their study.
