Using this approximate data, scientists can predict what the future will bring and can prepare for it. By lowering the use of fossil fuels, which when burned for energy create more CO2, we can lessen the ice shrinkage.
This can also be used by small coastal cities, by making them more prepared for ocean levels to rise and know when it’s necessary to evacuate or take precautionary measures.
We also now know that CO2 emissions directly affect ice levels so to stop the shrinkage of the ice, renewable energy sources should be found.
