Since life began on earth, changes in the global climate have affected the distribution of organisms as well as their interactions. However, human-induced increases in atmospheric concentrations of greenhouse gases are expected to cause much more rapid changes in the earth’s climate than have been experienced for millennia. If this happens, such high rates of change will probably result in local if not total extinction of some species, the alteration of species distributions in ways that may lead to major changes in their interactions with other species, and modifications in the flow of energy and cycling of materials within ecosystems.
THIS study is interesting but still doesn't address the FACT algae provide 60% of the breathable oxygen on Earth. If they die. We die.
In addition to all this bad news is the fact many of what is mentioned about sea level rise in regard to choking off coral reefs is in regard to PRESERVING out 'Carbon Sinks.'
The carbon sinks include algae, diatoms, coral reefs and terrestrially the primary producers of trees, grasslands and rainforests, both tropical as the Amazon and temperate as The Tongas.
