Impact of Global Warming and Climate Change on Marine Environment

According to the analysis of the article, it can be depicted that continued absorption of carbon dioxide by the swath of ocean surrounding Antarctica and subarctic parts of the Pacific Ocean would increase the ocean's acidity and prevent some marine life from growing protective shells, in turn threatening their survival. Other marine creatures would suffer from softened shells due to the acidic ocean water, making them susceptible to predators, the study said. Scientists did not know what the effect of the extinction of shelled creatures could have on organisms higher up on the food chain.

Increased carbon dioxide in the environment may alter surface temperature from the greenhouse effect, which changes the ground terrain, such as loss of glaciers, but more importantly changes biota, e.g., expansion of tropics and savannahs toward higher latitudes. At the current rate, it is hypothesized that global climate change can escalate significantly unless the solutions presented internationally by climate change experts and environmentalists are taken. The researchers said that existing protected areas for marine life were too small and scattered too far apart to offer any protection to migrating species. They also attributed the recent decline of several fish populations to improvements in fishing technology and new demands for seafood. The researchers included ecologists, resource economists and social scientists.

Climate change and extreme weather conditions will also be a result of global warming. Increased CO2 emission changes the ground terrain, such as loss of glaciers, but more importantly changes biota, e.g., expansion of tropics and savannahs toward higher latitudes. At the current rate, it is hypothesized that global climate change can escalate significantly unless the solutions presented internationally by climate change experts and environmentalists are taken seriously. The evidence of natural acts in the past year shows the significance of the future consequences. Nevertheless, industrialisation, deforestation and pollution the greenhouse; gases emitted have helped ensnare heat near the surface of earth. In this process humans dispense carbon dioxide into the atmosphere quicker than the plants and oceans can absorb it. This scenario can be witnessed by the rise in natural catastrophes causing severe amounts of life loss and the destruction of previously affluent areas in the world, the extraordinary heat wave and wildfires in Russia, and landslides caused by heavy rain.

According to the analysis of the article, it can be interpreted that the scientists used readings obtained from 7,200 weather stations located around the world to collect their data. Their analysis found that the average global temperature in 2005 was about 1.36 degrees Fahrenheit (0.75 degrees Celsius) higher than the average recorded between 1950 and 1980. In 1998, formerly the hottest year ever recorded, global temperatures were measured at degree 1.28 above the 1950 to 1980 average. Major floods almost always occurred after long periods of rainfall that saturated the ...
