Climate Change Introduction What is the oceans role in climate? The oceans play a vital and pivotal role in the distribution of life sustaining water throughout our planet. 86% of the evaporation that occurs on earth is over the oceans. The oceans are the planets largest reservoir of water transferring huge amounts of water around the hydrological cycle. In fact the oceans â€Å"dominate the hydrological cycle, for they contain 97% of the global water inventory† . The hydrological cycle can be disrupted by changes in ocean circulation that play such an important role on evaporation and precipitation. When the ocean circulation system changes it can change how much heat and rainfall is distributed around the world. Changes on a global†¦show more content†¦Broecker’s image of the conveyor belt is somewhat simplified. The ocean conveyor is propelled by the sinking of cold, salty (and therefore denser) waters in the North Atlantic Ocean. This band of deep water flowing south down through the depths of the Atlantic spreads into the Indian and Pacific oceans where it wells to the surface and mixes with other warm tropical waters, it also helps to pull warm, salty Gulf stream waters northward. The warm waters return back to the North Atlantic where mixed with colder Greenland waters and driven by bitter winds it becomes gradually colder saltier once again sinking into the deep. In reality much of the water that sinks in the Atlantic never leaves and other eddies and gyres across the oceans mean that this really is a simplified image of the conveyor belt but essentially the basic idea is true. The conveyor â€Å"transports heat into the North Atlantic and salt out of it†. Past History The earth’s past is full of dramatic climate changes. Many glacial advances and retreats have occurred during the last billion years of Earth history. Large, important glaciations occurred during the late Proterozoic (between about800 and 600 million years ago), during the Pennsylvanian and Permian (between about 350Show MoreRelatedClimate Changes And Climate Change Essay1458 Words   |  6 PagesAbstract: Climate is inherently variable. Climate changes from place to place and it varies with time. The world now faces one of the complex and important issue it has ever had to deal with: climate change. Climate change today is one of the biggest concerns of human beings on the planet and the effects of climate change are undeniable and it may cause environmental, social, and economic threats to the planet. We already know and easily can highlight several signs of climate change. They are: risingRead MoreClimate Changes And Climate Change1016 Words   |  5 Pagesâ€Å"Climate change is a reality that is happening now, and that we can see its impact across the world† (Haddrill, 2014) Climate change is the changes in the pattern of the climate due to natural and human activities that has been used inappropriately. Climate is defined as the â€Å"average weather† (Calow, 1998) for a particular region. Climate change is the human activities that affect Earth’s climate by using the human activities inappropriately that leads to the warming of the Earth. There are varietyRead MoreClimate Changes And Climate Change1081 Words   |  5 PagesThe concept of climate change has been around for quite a while. The earliest mention of climate change dates back to the 19th century. Swedish scientist, Svante Archenius was the first scientist to study the effect of CO2 on climate. (Rodhe et al 1997) The Intergovernmental Panel on Climate Change (IPCC) defines climate change as â€Å"A change in the state of the climate that can be identified (e.g by using statistical tests) by changes in mean and/or the variability of its properties and that persistsRead MoreClimate Changes And Climate Change935 Words   |  4 PagesClimate change is one of the most important challenges of humankind in this century. The ability to adapt, mitigate and reduce carbon emissions will be decisive to preserve the world for future generations. The last IPCC report has provided more evidence regarding the rise in temperature and sea level. Apparently, additional 2 °C above the pre-industrial average temperature levels is unavoidable, and it will continue at that level due the accumulation of gases in the atmosphere (Solomon 2009).

Many of us watch the news or use an app on our cellphones/electronic devices to keep an eye on the weather for the day, week, or even the month. But, there is actually a difference between weather and climate. Weather is actually â€Å"the changes we see and feel outside from day to day. It might rain one day and be sunny the next. Weather also changes from place to place† (Dunbar, 2014). Whereas â€Å"climate is the usual weatherRead MoreClimate Change Is The Change923 Words   |  4 PagesClimate change is the change in earth’s climate like temperature and precipitation over a particular region. Climate change has shown its affect all across the globe and is leading to all undesirable loses. Some of the reasons of radical climate changes are: †¢ Irresponsible activities of humans like misuse of fossil fuels, polluting water bodies and use of non-renewable sources †¢ Burning of fossil fuels like coal and oil are rising the levels of carbon dioxide in the air.

Climate change is a topic that is brought up in many different genres of conversations. Whether it be brought up and discussed in politics, school, family, or friends, some people still limit using those words when in casual conversation. Some of those same people are the people who still deny that climate change is happening. Climate change affects every single one of us. It affects everyone who lives on this earth every day andRead MoreThe Change Of The Climate Change1184 Words   |  5 Pages The world continues to spin and spin, and we’ve always heard about the condition of the climate. We hear about the changing levels of CO2 in our atmosphere and the Earth’s population contribution to the rise of it. No one usually stops to think about how the food production systems for the food we eat is also a contributing factor to the rise of CO2. â€Å"I turn my life upside-down, start biking to work, plan t a big garden, turn down the thermostat so low I need the Jimmy Carter signature cardiganRead MoreClimate Change3273 Words   |  14 Pages1. Introduction Scientific evidence of the world’s changing climate is unequivocal. The expected impacts of the changing climate are likely to adversely affect the well being of all countries and particularly the poorest countries, some of which are in Africa. The changing climate has been manifested in the form of: increased severity and frequency of droughts; floods and storms; water stress, coastal erosion, and higher incidence of vector borne diseases among others. The resulting declines inRead MoreClimate Changes And Climate Change Essay1656 Words   |  7 Pages Climate change is defined by the Intergovernmental panel on climate change ( IPCC) as a variation in the mean state of climate persisting for an extended period of time typically decades or longer while the United Nations Framework Convention on Climate Change (UNFCC) defines climate change as a change in the climate which is attributed directly or indirectly to human activities that alters the composition of the global atmos phere and which is in addition to natural climate variability observed
