As the temperature rises, global warming affects the seawater level; it melts the iceberg and adds more water to the ocean. Because the islands of Hawaii are small and surrounded by water, this poses a threat to Hawaii and other islands. This puts us at risk of coral reefs and people a lot. Global warming had a huge potential impact on Hawaii's environment, health, economy and natural resources. As the sea level rises, coral reefs are at risk.
The impact of global warming on the oceans provides information on the various effects of global warming on the ocean. Global warming affects sea surface, coastline, ocean acidification, ocean current, seawater, sea surface temperature, tidal, ocean floor, weather, and may cause changes in marine biogeochemistry, all of which are related to social activities It affects. The consensus in many studies on coastal tidal measurements is that over the past century the sea level has risen at an average rate of 1 to 2 mm / year, reflecting the net heat entering the land and sea. A corresponding study based on a satellite altimeter showed that this rate increased to nearly 3 mm / year during a more complete surveillance over the past 20 years. According to recent literature review, 30% of sea level rise since 1993 is due to thermal expansion, 55% is due to melting of continental ice, both due to the global temperature rise.
The main effects of global warming are climate change, sea level rise, and changes in wildlife behavior. These are the main influences of global warming, but they also contribute to a wide range of secondary influences. In recent years, the temperature of the earth is rising, which leads to climate change. By the end of this century the temperature of the world is expected to rise from 3 ° C to 5 ° C. Changes in air temperature patterns can affect extreme weather events. Increase the frequency, duration, intensity (cause and effect of global warming) of floods, droughts, heat waves, tornadoes.
