And its impact on fisheries, climate change
A study conducted by the Department of Aviation and Space
Administration (NASA), the US National Science Foundation and the veil
that climate change contributes to increased
temperatures flats lakes in the world quickly.These findings, published in Geophysical Research patrols and meeting of the American Geophysical Society in San Francisco last Wednesday.The study used the data temperatures taken by satellites and ground stations of 235 Lake around the world and included the analysis of temperature changes over the past 25 years.Sam Hawk scientific director of the Jet Propulsion Laboratory section of NASA and Co, said in the study, "All we want is to monitor how the lakes change in the entire world and to look at variations in temperature rise in the rates of the globe."Hawk said that the lake is witnessing a rise in temperature of 0.34 degrees Celsius on average every ten years due disparities in temperatures down to several factors, including shrinking the cover of clouds.It can be warmer lake temperatures to the destruction of the ecosystem in the lake leads him what can not be the continuation of live fish survival.Cook said that reducing pollution can contribute to reducing disparities in the lakes degrees temperature.Nor is the seas safe from this vulnerability warming.Scientists believe that the expectation of rising sea water temperature degree north by 1.8 degrees over the past 50 with the next, it will have an impact on the decline in a large number of fish, including haddock and plaice.Recently, National Oceanic and Atmospheric Administration has warned the United States that is very hot ocean exposed coral reefs around the world at risk, which requires urgent intervention.And beyond the importance of coral reefs aesthetic colors, they are vital to the ecosystems in the oceans, and even though it covers 0.1 percent of the ocean floor, but is also home to about 25 percent of marine species, and often referred to the reef as the rainforests of the seas.Coral reefs can deal with these fluctuations in the degree of severe and rapid heat and no, and especially as it has trouble keeping up with high rapid temperature resulting from global warming.Studies show that coral reefs will become extinct by 2050, and therefore must move quickly to reduce this rapid climate change and develop a strategy to reduce the phenomenon of global warming in the long term and caused by the continuous emission of gases, particularly carbon dioxide.

1 - The high proportion of carbon dioxide in the atmosphere is likely to lead to increased solubility in water in the oceans and seas, and thus increase the acidity of the water, which negatively affect the growth and reproduction of the life of the fish.
2 - Increase Egyptian Northern Lakes water salinity due to increased temperature, which leads to increase evaporation, thereby increasing salinity, as well as increased pollution year after year as a result of industrial and agricultural drainage and the lack of fresh water contained to the lakes, which leads to increased salinity more, affecting fry family migration rainfed from the sea to the confluence of fresh water areas and the least fish stocks in lakes.
3 - caused by climate modification change in the distribution of fish species of freshwater and saltwater fish stocks, with the direction of fish species in the waters where the temperature rises towards the poles, as well as reflect climate on seasonal vital biological processes in the form of changes in the fish food chains citizen water change fresh and salt, which returns the results can not be predicted at the level of fluctuations in fish production.
