UNESCO’s State of the Ocean Report found knowledge gaps in research & data on spiking oceanic warming.
As per the UNESCO State of Ocean Report, the world is still insufficient to design solutions for multiple ocean crises that can remove carbon dioxide from the atmosphere.
The upper 2,000 metres (m) of oceans warmed at a rate of 0.32 ± 0.03 watts per square metre (W/m2) between 1960 to 2023.
The rate of ocean warming has doubled in the last two decades. It has become a major concern for scientists.
The report provides regular data on how ocean warming is evolving and its impacts.
90 per cent of the EEI is absorbed by oceans. OHC is the total amount of heat stored by oceans.
Sea levels continued to rise in 2023. The global mean sea level from 1993 to 2023 increased at a rate of 3.4 +/-0.3 mm/yr.
The report highlighted that it is still not clear whether deoxygenation is accelerating in response to increased OHC.
The report notes that longer-term data sets are needed for coastal areas than for the open ocean.
This report has also mentioned the recent developments in marine carbon dioxide removal (mCDR) technologies.
EEI is the balance between incoming energy from the Sun and outgoing energy from the Earth.
