Since 1920 the mean sea level has risen by $3.20 \pm 0.25 \mathrm{~mm} /$ year in Lewes, Delaware, USA, estimate what is the temperature rise over a 100 year period assuming this is due to climate warming only.

Key Concepts

Mean Sea Level

Mean sea level refers to the average height of the ocean's surface relative to a reference point over a long period. It serves as a baseline for detecting long-term changes in sea level due to natural variability or human activities, and is a key indicator in studies related to climate change and global warming.

Sea Level Rise

Sea level rise is the increase in the global average level of the world's oceans, primarily driven by factors such as thermal expansion of seawater and the melting of glaciers and ice sheets. It is an important observable in climate science because it integrates the effects of both temperature changes and the cryosphere's response to global warming.

Thermal Expansion

Thermal expansion is the process by which water increases in volume as its temperature rises. In the context of climate change, as ocean water warms, it expands, which contributes significantly to the measured increase in sea level. This concept links ocean temperatures directly to changes in sea level over time.

Climate Warming

Climate warming refers to the rise in Earth's average surface temperature due largely to increased concentrations of greenhouse gases in the atmosphere. This warming affects various environmental indicators, including sea level, and is a central concept in understanding the impacts of climate change on natural systems.

Estimation Techniques

Estimation techniques in climate science involve converting observed changes, such as sea level rise, into corresponding changes in other variables like temperature. This often requires the use of empirical relationships, conversion factors, or modeling approaches to translate physical measurements into estimates of climate forcing or temperature increase over time.
