The ocean can be described as the world's largest ecosystem and it is home for many species of marine life. Different activities carried out and caused by human beings such as global warming, ocean acidification, and pollution affect marine life and its habitats.
It is clear that the ocean is warming as a result of climate change, and this rate of warming is increasing. [2]: 9 The global ocean was the warmest it had ever been recorded by humans in 2022. [13] This is determined by the ocean heat content, which exceeded the previous 2021 maximum in 2022. [13]
Ocean acidification has been called the "evil twin of global warming" and "the other CO 2 problem". [ 22 ] [ 23 ] Increased ocean temperatures and oxygen loss act concurrently with ocean acidification and constitute the "deadly trio" of climate change pressures on the marine environment. [ 24 ]
The Selli Event, also known as OAE1a, was an oceanic anoxic event (OAE) of global scale that occurred during the Aptian stage of the Early Cretaceous, about 120.5 million years ago (Ma). [1] The OAE is associated with large igneous province volcanism and an extinction event of marine organisms driven by global warming, ocean acidification, and ...
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
The ocean is a critical climate solution—although concerns exist around some ‘blue carbon’ methods.
The long-term effects of climate change on oceans include further ice melt, ocean warming, sea level rise, ocean acidification and ocean deoxygenation. [208] The timescale of long-term impacts are centuries to millennia due to CO 2 's long atmospheric lifetime. [209]
Problems of global warming, climate change, and their various negative impacts on human life and on the functioning of entire societies are one of the most dramatic challenges of modern times. PAS General Assembly calls on the national scientific communities and the national government to actively support Polish participation in this important ...
