Dynamics of The Tropical Atmosphere and Oceans; Radar Meteorology: A First Course . These gases are the main cause of climate change and the greenhouse effect [1]. The effects of climate change on oceans include the rise in sea level from ocean warming and ice sheet melting, and changes in pH value (ocean acidification), circulation, and stratification due to changing temperatures leading to changes in oxygen concentrations.There is clear evidence that the Earth is warming due to anthropogenic emissions of greenhouse gases and leading inevitably to ocean . able to deal with climate change have been clear: We can act to mit-igate the future effects of climate change by addressing the factors that cause changes in climate, and we can adapt to changes in climate by addressing the factors that make society and the environment vul-nerable to the effects of climate. Environmental causes. Greenhouse gases are carbon monoxide and sulphur dioxide it trap the solar heats rays and prevent it from escaping from the surface of the earth. But we must also prepare for the significant and unavoidable consequences of carbon emissions such as increasing temperatures, shifting precipitaton patterns, ocean acidification, sea level rise and the increasing intensity and frequency of extreme weather events. Drought can harm food production and human health. South Africa is faced with a difficult challenge in trying to juggle three imperatives - development (conventionally based on fossil fuels), poverty eradication and climate change. The way the body heals. The potential to protect, restore and use ecosystems as tools to tackle climate change has gained increasing traction under the broad/overarching framework of NbS, or 'natural climate solutions' (NCS) where the context is mitigation of climate change . Climate change has caused drastic effects in the world climate, such as the rise of carbon dioxide level, global temperature, melting of ice sheets, rise of sea levels, and ocean acidification . climate change talks and its leverage in demanding emissions cuts from rich countries. The communiqu stated that climate change is a development issue that should be mainstreamed into various sectors of national, regional and state development plans. Since then they've written several reports, all with the same conclusion: " climate change is real and human activities are the main cause." 4B/H5 Climatic conditions result from latitude, altitude, and from the position of mountain ranges, oceans, and lakes. For example, the fact that global warming causes rain to fall less frequently in deserts will have a negligible effect, but the fact that global warming may alter mid-Atlantic air currents means that whole . Flooding and rising sea levels can contaminate land and . Increased intensities of hurricanes and heavier rains in many parts of the country. This time both government and market failed. Extreme weather events are making water more scarce, more unpredictable, more polluted or all three. The rate of warming per decade has been around 0.15 -0.2 Celsius.
