Arctic Ocean could be ice-free in summer by 2030s, say scientists
The HinduThe Arctic Ocean could be ice-free in summer by the 2030s, even if we do a good job of reducing emissions between now and then. As it is at the frontline of climate change, the eyes of many scientists and local indigenous people have been on the sea ice that covers much of the Arctic Ocean in winter. Data | Antarctic sea ice cover hits record lows on many days of 2023 As a consequence, there has been considerable effort invested in determining when the Arctic Ocean might first become ice-free in summer, sometimes called a “blue ocean event” and defined as when the sea ice area drops below 1 million sq. Melting faster than models predicted Back in the 2000s, an assessment of early generations of climate models found they generally underpredicted the loss of sea ice when compared to satellite data showing what actually happened.
