How Much Has the Ocean Warmed? IPCC Findings on Rising Sea Temperatures

Per the IPCC, the global ocean has warmed ~1.1°C (2°F) since the late 19th century, driven by greenhouse gas emissions from fossil fuel burning.

Consequences

• Sea Level Rise: Thermal expansion + glacial melt.
• Stronger Storms: More energy fuels hurricanes/cyclones.
• Current Shifts: Alters weather patterns, marine ecosystems.
• Ocean Acidification: CO₂ absorption lowers pH, harms corals/shellfish.

Urgent emission reductions are needed to mitigate these accelerating impacts.
