Consider the following statements:
1. From 1960 through 2023, the upper 2,000 metres of oceans warmed at a rate of 0.32 ± 0.03 watt per square metre (W/m²).
2. Increased Ocean Heat Content (OHC) prevents ocean layers from mixing and deoxygenating, lowering the preformed oxygen content of near-surface high-latitude waters reaching the deeper layers of oceans.
3. The average global surface ocean pH has declined continuously by 0.017-0.027 pH units per decade in the open ocean since the late 1980s.

1. Statement 1 is correct. According to the UNESCO State of the Ocean Report 2024, from 1960 through 2023, the upper 2,000 metres of oceans warmed at a rate of 0.32 ± 0.03 watt per square metre (W/m²).
2. Statement 2 is correct. Increased Ocean Heat Content (OHC) indeed prevents ocean layers from mixing and deoxygenating, lowering the preformed oxygen content of near-surface high-latitude waters reaching the deeper layers of oceans.
3. Statement 3 is correct. The report also mentions that the average global surface ocean pH has declined continuously by 0.017-0.027 pH units per decade in the open ocean since the late 1980s.
Thus, all statements 1, 2, and 3 are correct.
