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.
Scientists are running out of extreme adjectives to describe the state of the world’s oceans.
Climate scientists called on Heartland to "recognise how its attacks on science and scientists have poisoned the debate about climate change policy." [ 21 ] Gleick described his actions in obtaining the documents as "a serious lapse of my own and professional judgment and ethics" and said that he "deeply regret[ted his] own actions in this case".
Although the upper 2000 m of the oceans have experienced warming on average since the 1970s, the rate of ocean warming varies regionally with the subpolar North Atlantic warming more slowly and the Southern Ocean taking up a disproportionate large amount of heat due to anthropogenic greenhouse gas emissions.

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 .
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 world is closing out ... Preliminary data from the Copernicus Climate Change Service shows that global temperature anomalies reached between 1.5 and 1.6 degrees Celsius (between 2.7 and 2.9 ...
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]
