The world's oceans are turning acidic due to the buildup of carbon dioxide (CO2) in the atmosphere, and scientists say the effects on marine life will be catastrophic.

“Increasing levels of carbon dioxide in the atmosphere may make Earth's oceans more acidic faster than previously thought—unbalancing ecosystems in the process. New study says: Helen Scales for National Geographic News” For tens of millions of years, Earth's oceans have maintained a relatively stable acidity level. It's within this steady environment that the rich and varied web of life in today's seas has arisen and flourished. But research shows that this ancient balance is being undone by a recent and rapid drop in surface pH that could have devastating global consequences. Read more [...]

Humans change the world! What drought are you talking about? A drought is a period of unusually persistent dry weather that persists long enough to cause serious problems such as crop damage and or water supply shortages. The severity depends upon the degree of moisture deficiency, the duration, and the size of the affected area. The major effects of climate change on water systems take place through changes in the hydrological cycle, basically the balance between temperature, and rainfall. Whilst some regions may have higher rainfalls this can evaporate through sustained increases in temperature... Read more [...]
