The top of the Earth set another record for low sea ice levels and scientists say it is a sign of overheating world.
The floating ice in the Arctic hit a new low in winter: 5.57 million square miles. That counts to about 35,000 square miles an area about the size of Maine.
This puts the Arctic into a “deep hole” with the crucial summer and spring melt season starts and more regions are going to be ice-free, said Mark Serreze, the National Snow and Ice Data Center Director in Colorado. He said, ‘It is the key part of the climate system of the earth and we are losing it and in fact, we are losing in all seasons the ice”.
At the same time, Antarctica, sea ice also reaches its lowest point in March, hitting a low mark. Antarctic sea ice varies unlike Arctic sea ice that is steadily decreasing.
Several scientists regard the sea ice loss disturbing. “It’s evidence that the climate at the world top continues to change faster than on Earth and the impacts are still frankly unknown,” said in an email, David W. Titley, Pennsylvania State University meteorology professor and retired admiral.
Scientists blame the combination of natural weather and man-made global warming from the burning of coal, gas and oil. The 2016-2017 winters were unusually toasty and the Arctic experienced three “extreme heat waves,” said Serreze.
“The Arctic is the main in the climate’s coal mine,” said Katharine Hayhoe, the Texas Tech climate scientist. “What happens in the Arctic affects all. This entire planet is interconnected.”
