![]() Scientists thus look to the polar regions first to understand the impacts of global warming on our planet. This changes the temperature, depth, and direction of ocean currents, which in turn changes weather and climate around the world. Just a flat, cold, windy desert.Īs our planet warms, ice at the poles melts. Blizzards are common in Antarctica because nothing holds the powdery snow in place. But when it does snow, it stays around – for centuries. It rarely snows because the temperature is too cold. It turns out that the poles (especially Antarctica) are actually very dry. But there is much to learn about polar climates and how fluctuations in planetary conditions are often first noticed in these extreme locations. ![]() What do hurricanes, droughts, tornadoes, and floods have to do with the polar regions? When we think of the poles, we imagine snow storms and cold temperatures. ![]()
