<h3>What is a long-term climate cycle?</h3>
Long-term climatic cycles are climatic variations that are characterized by developing climatic changes over long periods of time.
For example, the current climate change has lasted for more than a hundred years, in which the temperature of the atmosphere has increased and this has triggered other climatic manifestations such as:
- Extreme temperatures.
- Ocean level rise.
- Melting at the poles.
- Decrease in snowy peaks.
- Among others.
These processes typically take more than a lifetime because they are long-term processes that include small variations that result in large changes in climate and other aspects of the Earth.
