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.
While hiatus periods have appeared in surface-air temperature records, other components of the climate system associated with warming have continued. Sea level rise has not stopped in recent years, [30] and Arctic sea ice decline has continued. There have been repeated records set for extreme surface temperatures. [31] [32] [33]
Driven by oceans that won't cool down, an unseasonably warm Antarctica and worsening climate change, Earth's record hot streak dialed up this week, making Sunday, then Monday, the hottest days ...
The oceans have heated more slowly than the land, but plants and animals in the ocean have migrated towards the colder poles faster than species on land. [222] Just as on land, heat waves in the ocean occur more frequently due to climate change, harming a wide range of organisms such as corals, kelp, and seabirds. [223]
AMOC-Index since 900 CE with pronounced slowdown since ~1850; Rahmstorf et al. (2015) [5] Climate scientists Michael Mann of Penn State and Stefan Rahmstorf from the Potsdam Institute for Climate Impact Research suggested that the observed cold pattern during years of temperature records is a sign that the Atlantic Ocean's Meridional overturning circulation (AMOC) may be weakening.
Studies have found that Earth’s oceans have absorbed about 90% of the heat trapped on the planet from greenhouse gas emissions since 1970. ... compounding background warming from climate change ...
Both of them also appear to be slowing down due to climate change, as the melting of the ice sheets dilutes salty flows such as the Antarctic bottom water. [ 9 ] [ 10 ] Either one could outright collapse to a much weaker state, which would be an example of tipping points in the climate system .
The shutting down of the current would also mean that warm water in the middle latitudes would get even warmer, potentially giving rise to more tropical storms and hurricanes.
