An international team of climate scientists has used 627 years of coral records in Fiji to reveal unprecedented insights into Pacific ocean temperature and climate changes since 1370.
New coral records show that local ocean temperatures were warmer between 1380 and 1553, comparable to those in the late 20th and early 21st centuries. However, when combined with other coral records, the Pacific-wide warming observed since 1920 (largely attributed to human emissions) marks a significant departure from natural changes recorded in previous centuries.

We can safely ignore the often dismissive claim that it proves “climate change.” As always, if the study did not mention climate change, it would not be funded or published. Therefore, the author appeals:
Their chart shows no evidence of their attribution:
(D) Annual mean Sr/Ca-SST (red) of Fiji coral core F14 compared to Fiji composite
Coral records for records 1F and AB (23) (green) for the common period 1781 to 1997.
(D) Compared with the Ocean2K SST anomaly reconstruction in the western Pacific (24) (blue) and the SST anomaly reconstruction at PHYDA near Fiji (17°S, 117°E) (21) (green). Also shown
is the latest sea surface temperature data for Fiji ERSSTv5 (1998 to 2021), shown in (E) (black). Sea surface temperatures appear as anomalies relative to the period 1883 to 1996.
The 1F and AB (23) records from Fiji are also included in the PHYDA and O2KWP reconstructions. Triangles in (D) and (E) indicate the timing of major volcanic events (<−3.5 W/
m2 value) (Fig. 2) (22) is generally related to the cooling response. Red (blue) bars based on change points in (D) and (E) highlight extended warm (cold) periods
(E) The composite analysis for Fiji shown is represented by the dark red vertical line; the dark red horizontal line represents the average for each period.
We didn't just see the warm period before the LIA arrived.
Clearly, natural variability dominated the entire period, which is not surprising since a warm atmosphere does not significantly increase ocean temperatures.
We should also ignore the black line showing current sea surface temperature – splicing the data in this way is strictly prohibited in any statistical analysis.
