Polar ice caps are melting as global warming causes climate change. We lose Arctic sea ice at a rate of almost 13% per decade, and over the past 30 years, the oldest and thickest ice in the Arctic has declined by a stunning 95%.

How is climate change affecting the ice caps?
A warmer climate affects ice sheets in several ways. The most evident impact observed to date is a loss of ice due to warmer air and ocean waters. Warmer air causes the ice to melt more quickly and flow more rapidly to the sea, especially in low-elevation regions near the edges of the ice sheets.
What are the effects of ice caps melting?
What are the effects of melting glaciers on sea level rise? Melting glaciers add to rising sea levels, which in turn increases coastal erosion and elevates storm surge as warming air and ocean temperatures create more frequent and intense coastal storms like hurricanes and typhoons.
What are the effects of polar ice caps?
There are numerous effects, ranging from extreme natural events (including droughts and flooding), to sea level and temperature changes, to the possibility of toxins, including deadly viruses, finding their way into the environment as ice and permafrost melt and release gases and other elements into the environment.
What would happen if the polar ice caps all melted?
If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet). The ocean would cover all the coastal cities. And land area would shrink significantly. But many cities, such as Denver, would survive.
What is the cause of the polar ice caps melting?
The burning of fossil fuels has resulted in the buildup of greenhouse gases in the environment thus influencing the warming trend because they trap heat in the atmosphere. The increase in temperatures is causing more and more glaciers to melt, consequently, this ends up exposing the earth underneath.
How does volcanic activity affect climate?
Volcanic eruptions of this magnitude can impact global climate, reducing the amount of solar radiation reaching the Earth's surface, lowering temperatures in the troposphere, and changing atmospheric circulation patterns.
What is this climate change?
Climate change refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, such as through variations in the solar cycle. But since the 1800s, human activities have been the main driver of climate change, primarily due to burning fossil fuels like coal, oil and gas.
What climate change means?
Climate change is a long-term change in the average weather patterns that have come to define Earth's local, regional and global climates. These changes have a broad range of observed effects that are synonymous with the term.
