From 1993 to 2023, four climate signals tell the same broad story:
warmer ocean water, warmer surface temperatures, a higher sea level,
and increasingly volatile rainfall.
+0.42°C
change in 10-year mean ocean temperature anomaly
+0.40°C
change in 10-year mean surface temperature anomaly
+10.0 cm
change in 10-year mean sea-level anomaly
+102%
change in 10-year rainfall variability
A fingerprint in motion
Each column below is a rolling 10-year window. Darker cells indicate
where that climate signal sits closer to the highest 10-year value
observed in Samoa during 1993–2023.
Temperature and sea level use 10-year mean anomalies.
Rainfall volatility is measured using the standard deviation of annual
precipitation anomalies within each 10-year window.
