How are the oceans affected by global warming and climate change?

Higher temperatures are bad for fish development, growth, feeding, and spawning, and causes coral bleaching. Polar ice is melting, causing the loss of habitat for Arctic animals, Antarctic krill decline, and algae diminishing, which is serious because it's the foundation of the Arctic food web. Rising sea levels will flood 10% of the world's population, because they live at or below sea level, small island nations in the Pacific ocean will be wiped off the map, coral reefs, mangroves, and sea grasses will be unable to keep up with the rising sea levels, and critical coastal habitats, such as sea turtle nesting beaches, will disappear. Warming the oceans alters sea currants and changes the chemistry of seawater. This changes marine species' migratory patterns, and many species that depend on the currant for nutrients or reproduction will be affected by it. Oceans with high carbonic acid harm shell-forming organisms, such as corals, scallops, lobsters, crabs, and some microscopic plankton that are a foundation of the food web across the ocean. Increased acidification limits the ability of certain fish to detect predators, disturbing the food chain.

explanation:

b,bacteria convert nitrates

into nitrogen gas.

d,plants and animals take in

and use nitrogen compounds.

e,bacteria break down waste    

products and return nitrogen  

to the soil.

a,bacteria convert atmospheric

nitrogen to ammonia.

c,bacteria convert ammonia

to nitrites and nitrates.

the "dirty dozen" chemicals banned in an international treaty are formally known as persistent organic pollutants, or pops. the united nations environment program provided this background on what they are and what they can do to humans and wildlife.
