Due to global warming and increased glacier melt, thermohaline circulation patterns may be altered by increasing amounts of freshwater released into oceans and, therefore, changing ocean salinity. Thermohaline circulation is responsible for bringing up cold, nutrient-rich water from the depths of the ocean, a process known as upwelling .
A 2020 study reports that by 2050 global warming could be spreading in the deep ocean seven times faster than it is now, even if emissions of greenhouse gases are cut. Warming in mesopelagic and deeper layers could have major consequences for the deep ocean food web, since ocean species will need to move to stay at survival temperatures. [69] [70]
Plant And Animal Habitats Face Dire Threat From Warming Climate. Each year, more species are losing their habitats to climate change. An increase of 4 degrees Celsius in average planetary temperatures could result in severe habitat loss for almost two-thirds of plant species and one-third of mammal species. +2 degrees +4 degrees

In Asia, global warming of 1.5 °C (2.7 °F) will reduce the ice mass of Asia's high mountains by about 29–43%,: [56] Approximately 2.4 billion people live in the drainage basin of the Himalayan rivers: [57] In India alone, the river Ganges provides water for drinking and farming for more than 500 million people.
It therefore can be seen as a contributor to global warming. [28] Many ecological effects will be compounded by climate change as well, as ambient temperature rises in water bodies. [11] Spacial and climatic factors can impact the severity of water warming due to thermal pollution. High wind speeds tend to increase the impact of thermal pollution.
Based on his reanalysis of sedimentary rock record, he estimated that the loss of over 60% of marine species and over 35% of marine genera was correlated to a >7 °C (13 °F) global cooling and a 7–9 °C (13–16 °F) global warming, while for the terrestrial tetrapods, the same losses would be seen under ~7 °C (13 °F) of global cooling or ...
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 ...
