NASA | Sea Ice Max 2013: An Interesting Year for Arctic Sea Ice

The Arctic Ocean's ice has reached its maximum extent, marking the 5th smallest winter peak in 35 years. Seasonal changes show a trend of decreasing ice, with the lowest extent recorded in 2012. Factors like warm temperatures and cyclones contribute to ice melt, while thinner ice leads to fracturing events. Despite this year's smaller maximum, it doesn't guarantee a record low in summer, but the thinning ice cap increases vulnerability to future melting, potentially leading to ice-free Arctic summers in a few decades.
