The Climate Shift Index: Ocean (Ocean CSI) global map shows the influence of climate change on daily sea surface temperatures around the globe.
Our ocean is changing. With 70 percent of the planet covered in water, the seas are important drivers of the global climate. Yet increasing greenhouse gases from human activities are altering the ocean before our eyes. NASA and its partners are on a mission to find out more.
The Global Ocean Monitoring and Observing Program conducts long-term ocean observations that help us better predict and prepare for the impacts of hotter seas, including rising coastlines, changing fisheries, coral bleaching, and more frequent storms.
On this page, you will find global data and research on the impacts of climate change, including temperature anomalies, sea level rise, sea ice melt, glacier loss, and ocean acidification. See all of our interactive charts on climate change ↓
There are many effects of climate change on oceans. One of the most important is an increase in ocean temperatures. More frequent marine heatwaves are linked to this. The rising temperature contributes to a rise in sea levels due to the expansion of water as it warms and the melting of ice sheets on land.
Fuelled by climate change, the world's oceans have broken temperature records every single day over the past year, a BBC analysis finds. Nearly 50 days have smashed existing highs for the time...
