island nations are likely to become uninhabitable due to oceanic and cryospheric climate change, according to the report, but habitability thresholds remain extremely difficult to assess. Some island nations are likely to become uninhabitable due to oceanic and cryospheric climate change The risks will be further intensified by an increase in the average intensity, storm surge magnitude, and precipitation rates of tropical cyclones, especially if greenhouse gas emissions continue to increase. “Various adaptation approaches are already being implemented, often in response to flood events. The report highlights the diversity of options available for each context and for the development of integrated responses that anticipate future sea level rise on a full

scale.” Masson-Delmotte concluded. Changes in Niger Email List ocean ecosystems The report also highlights that warming and chemical changes in the oceans are already altering species throughout the ocean’s food web, with impacts on marine ecosystems and the people who depend on them. To date, the ocean has absorbed more than 90% of the excess heat in the climate system. By 2100, the ocean will absorb between two and four times more heat than between 1970 and the present if global warming is limited to 2 ° C, and five to seven times more with higher emissions. “The warming of the ocean reduces the mixing between the layers of water and, as a consequence, the supply of oxygen and nutrients for marine life”, explain the scientists. Additionally,

marine heat waves have doubled in frequency since 1982 and are projected to increase further in frequency, duration, extent, and intensity. Its frequency will be 20 times higher at 2 ° C of warming, compared to pre-industrial levels. They would occur 50 times more often if emissions continue to increase. Warming and acidification of the oceans , loss of oxygen and changes in nutrient supply are already affecting the distribution and abundance of marine life in coastal areas, in the open ocean and on the sea floor. Marine heat waves have doubled in frequency since 1982 and are increasing in intensity “Reducing greenhouse gas emissions will limit the impacts on ocean ecosystems that provide us with food, support our health and shape our cultures,”
