Climate change is a change in the average global or regional weather patterns. Climate changes includes factors such as; temperature, precipitation, humidity, wind and seasons, influenced by oceans, land surfaces and ice sheets. This plays a
Climate change is defined as the change in global or regional climate patterns, which is apparent from the mid to late 20th century onwards. When looking at climate change there is an abundance of evidence that supports that humans are the leading causes of the drastic shift in the weather pattern but there is also a lot of evidence against humans actually causing climate changes. For example, the increasing levels of man made gases that are let into the atmosphere may have created a greenhouse effect, which traps heat and ultimately causes global warming. But there are also many scientists who believe that the earth has always naturally cooled down or warmed up at its own pace.
Scientists refer to global climate change as any alteration in the average temperature involving the climate system. The climate system involves the following: our atmosphere, including temperature, clouds and wind, precipitation, humidity, atmosphere trace gas and aerosol distribution; oceans; volcanoes; land; cryosphere, which includes ice cover and snow cover; and the sun (Murck, Skinner, & Mackenzie, 2010). The alternations have been
Climate change can be defined as a significant change in the “average weather” of any given region sustained in the long-term and can be caused by Earth 's dynamic processes, external forces including variations in sunlight intensity, and also by human activities (USEPA, 2014).
Climate change is quickly affecting many social and economic sectors, both directly and indirectly. This is particularly true within the natural habitat sector, as varying impacts on global biodiversity threaten the existence of many species world-wide. While many problems such as warmer temperatures and rising sea levels are attributed to increasing carbon dioxide (CO2), there is one crucial problem that is often overlooked: Ocean acidification. As pH levels in the ocean fluctuate, there are devastating effects on sensitive marine ecosystems and individual species. Increased acidic conditions can pose threats to habitats, such as coral reefs and sea grasses (Guinotte and Fabry 320). These living habitats rely on calcium carbonate to form strong external structures, yet higher pH levels inhibit the organisms’ ability to successfully absorb the compounds needed for this process. Additionally, higher levels of ocean acidification can induce decreases in skeletal-forming compounds, diminishing entire populations of small ocean organisms such as crustaceans and phytoplankton (Doney). Therefore, it can be deduced that the increase of greenhouse gases in the atmosphere cripple the marine wildlife ecosystems, because the addition of greenhouse gases, caused primarily by anthropogenic conditions, are acidifying the ocean and disrupting the bio-chemical compounds that are necessary for many marine species to survive.
The UNFCC also defines climate change as “a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over time periods.”
Climate change is the term used to describe the warming of the average surface temperature on earth. Climate change; often referred to as the general term global warming, is a topic that often inspires fierce debate among those on both sides of the issue. One thing those who are pro and those that are con both agree on is that the temperature on earth has increased over the past century by an average of 1.4 degrees. The big debate on the two sides is if the warming temperatures are caused by human activities and if it is not stopped it will have dire consequences (the pro side) or if it is the result of natural causes and the earth’s surface will find ways to adapt such as crops becoming more heat resistant (the con side).
Climate is sometimes confused with weather, which can lead some people to think that an abnormally cold day can mean that climate change and global warming is a myth. Climate is the weather conditions of an area over an extended period. Climate change is the current warming trend of weather mainly caused by human activities. According to a report written by NASA on global climate change, the main cause of this new human induced, climate change is what’s known as the “greenhouse effect.” The greenhouse effect results when the atmosphere traps gasses, such as carbon dioxide, nitrogen, and methane which causes earth to trap heat (“Global Climate Change”). According to a report by the Washington State Department of Ecology, carbon dioxide and other heat-trapping gasses caused by humans have warmed the earth and are causing many negative
Climate change is defined as “a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.” Climate change has happened as a cycle throughout history, with ice ages occurring, and then warming. The earth naturally warms and cools, but due to the burning of fossil fuels the rate is growing exponentially.
Climate change is when there is an identifiable change in weather over time. Unlike weather, scientists can predict the climate for the next fifty years; they can predict the changes in the atmospheric composition and the long-term weather in a certain area. Climate change is the predicted average weather and the change in an average weather, also known as the different temperatures, seasons, and precipitation. Climate can be viewed within the entire Earth itself, rather than just one place. This means that the Earth can have changes in the atmosphere, land, oceans, precipitation, and land. The Earth’s climate is always changing. An example of climate change within the entire Earth, between summer and winer. The seasons change because of geographical patterns of energy absorbed and radiated away by the Earth. Climate changes are formed by the changes in heat energy in the Earth’s system. Human activities are also a major factor to climate changes. Humans have made various changes in the amounts of greenhouse gases in the atmosphere, as well as changes made in the land.
Climate change is when there are different measures of climate during a period of time. It includes, big changes in the weather regarding temperature, wind patterns and more that occur over several years. (EPA, 2014)
Climate change could be described as any process that causes adjustment to climate system be it a volcanic eruption to a change in the solar activity. Today, however, the phrase is most often used as climate change caused by humans. Climate change is also used commonly with another phrase – "global warming" – reflecting scientific observations of strong warming trends over the past century or so. Indicators like rising sea levels, retreating snow cover and glaciers, longer growing seasons and shifting wildlife has alarmed scientific community unanimously agreeing that the earth has warmed in the last century. Experts however are of the opinion that climate change is a more accurate phrase than global warming as the latter is just one component affecting the larger climate systems of the earth.
