A recent scientific analysis published in Advances in Atmospheric Science confirms that 2025 was the warmest year on record for the world’s oceans since measurements began in the 1960s. The oceans absorbed an additional 23 zettajoules of energy, which is equivalent to 12 Hiroshima-scale explosions every second.
Because oceans absorb more than 90% of excess heat caused by greenhouse gas emissions, ocean heat content is a key indicator of accelerating climate change and its physical impacts.

Why this matters for coastal assets
Rising ocean temperatures contribute directly to sea level rise, stronger storms, and increased coastal and ocean flooding. These hazards pose growing risks for coastal infrastructure, real estate, ports, energy facilities, and other assets located near the shoreline.
For asset owners, insurers, and financial institutions, understanding where and how these risks materialize is critical for protecting value and making informed decisions.
How Climatig helps
Climatig helps organizations measure and manage coastal and ocean flooding risk driven by a warming climate.
Our platform enables users to:
- Assess sea level rise and coastal flooding risk at asset level
- Apply climate scenarios to understand how risks evolve over time
- Support investment, lending, and insurance decisions with consistent, data-driven insights
Scientific findings like record ocean heat provide the signal.
Climatig translates that signal into decision-ready intelligence, helping organizations manage climate risk where it matters most.
