Climate variability can also result from external forcing, when events outside of the climate system's components produce changes within the system. Examples include changes in solar output and volcanism. Climate variability has consequences for sea level changes, plant life, and mass extinctions; it also affects human societies.
Over the years, the definitions of climate variability and the related term climate change have shifted. While the term climate change now implies change that is both long-term and of human causation, in the 1960s the word climate change was used for what we now describe as climate variability, that is, climatic inconsistencies and anomalies.

This image shows three examples of internal climate variability measured between 1950 and 2012: the El Niño–Southern oscillation, the Arctic oscillation, and the North Atlantic oscillation. [114] In climate change science, ENSO is known as one of the internal [clarification needed] climate variability phenomena.
Climate variability and change occurs when changes in Earth's climate system result in new weather patterns that remain in place for an extended period of time. This length of time can be as short as a few decades to as long as millions of years.
Climate concerns the atmospheric condition during an extended to indefinite period of time; weather is the condition of the atmosphere during a relative brief period of time. The main topics of research are the study of climate variability, mechanisms of climate changes and modern climate change.
Warmer springs bring changes in bird migration. Spring’s arrival has always shown variation. It may be early. It may be late. But researchers say the data studied over several decades shows ...
Natural forces cause some variability, but the 20-year average shows the progressive influence of human activity. [2] Present-day climate change includes both global warming—the ongoing increase in global average temperature—and its wider effects on Earth’s climate system.
Warmer-climate wines tend to be riper than their cool-climate counterparts, which typically possess more mouthwatering acidity. As a result, they often play different roles at the table.
