Temperature reconstruction

Temperature reconstruction involves estimating past climate conditions by analyzing natural records such as tree rings, ice cores, sediment layers, and historical documents. These records contain clues—like ring thickness or chemical compositions—that reflect the climate at specific times. Scientists study these clues to create a timeline of how temperatures have changed over hundreds or thousands of years. This helps us understand long-term climate patterns, natural variability, and how current temperatures compare historically. Essentially, temperature reconstruction is a way to look back in time to see how Earth's climate has evolved over the ages.
