What do you think is behind this year's record ocean warmth?

Copernicus data shows July's average ocean surface temperature outside polar waters was 20.96°C, 0.07°C above the 2023 record — following a record-warm June. Both long-term warming and this year's strong El Niño may be playing a role.

• Clearly the acceleration of long-term climate change
• Mainly this year's strong, temporary El Niño effect
• Both together — impossible to fully separate them
• I doubt the phenomenon can be measured this precisely
