For example:
• The cryosphere—the frozen water on Earth—is melting. A warmer atmosphere causes the planet's snow pack, glaciers and sea and freshwater ice to melt at an accelerated pace. Melting glaciers and polar ice sheets contribute to sea level rise. As the ice melts, it also exposes more dark ocean waters, which absorbs more sunlight than ice, and thus heats the ocean more, triggering a cycle of melting and heating
