lämpenemisjakso

A lämpenemisjakso, or warming period, refers to a phase of increasing global or regional temperatures. These periods can occur over various timescales, from decades to millennia, and are distinct from the overall trend of anthropogenic climate change. Natural factors such as variations in solar activity, volcanic eruptions, and oceanic cycles can contribute to or influence these warming intervals. Understanding past lämpenemisjakso helps scientists differentiate natural climate variability from human-induced warming.

Historically, Earth has experienced numerous natural warming periods, such as the Medieval Warm Period, which lasted roughly from 950 to 1250 AD. During this time, temperatures in some regions were comparable to or even warmer than those in the late 20th century. These natural fluctuations have often been linked to changes in ocean currents and atmospheric circulation patterns. Scientists study the causes and impacts of these past events to improve climate models and better predict future climate scenarios. Distinguishing between natural lämpenemisjakso and the current sustained warming trend is a critical aspect of climate science.
