greenhouse gases and global warming

The ocean is one ecosystem that is being affected greatly by greenhouse gases. Tropical storms and hurricanes, as well as some other weather related events, depend on warm water to draw energy from. As global warming from greenhouse gases affects the world ecosystems the ocean is one of those affected. Warmer water means an increase in tropical storms and worse, both in frequency and in intensity. Hurricanes and tropical storms need warm water to draw energy from, and global arming is providing this. Look at Hurricane Katrina, one of the worst displays of the true fury of mother nature in America and one of the most devastating hurricanes to ever reach the US. In the last ten years, storms that are more powerful have been occurring more frequently, and if greenhouse gases continue to contribute to global warming it will only get worse because of the damage done to the world ecosystems.

Global warming is causing the glaciers and arctic ice cap that has been preserved for millions of years to melt faster, and this can affect many different ecosystems. The flow of colder water from the melting ice is flowing into the sea much faster, which can cool down the warm water flows that are necessary for tropical marine life. Tropical fish and animals may not be able to survive if the water temperature changes drastically, and marine life that can absorb carbon may do so increasingly and become threatened. The pristine lands and habitats that are around the melting ice can also be adversely affected.
