Explanation:
The most worrisome problem lies at the north pole, where most of the ice floats on water.
Long-term changes in temperature and weather patterns are referred to as climate change. These shifts may be natural, but human activities have been the primary driver of climate change since the 1800s, primarily due to the combustion of fossil fuels (such as coal, oil, and gas), which produces heat-trapping gases.
Even if emissions are significantly reduced in the coming decades, more than a third of the world's remaining glaciers will melt before the year 2100. When it comes to sea ice, 95% of the Arctic's oldest and thickest ice has already melted.
As our planet warms due to climate change, the world's ice is melting faster than ever. In most mountainous areas, glaciers are receding. Greenland's and Antarctica's ice sheets are receding.
