Solar variation

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

cause of climate change is solar irradiance, a measurement of solar power received from the sun and measured at the Earth. Studies have shown that changes in solar irradiance have contributed to climate trends in the past. According to National Aeronautics and Space Administration (NASA), an example of this is the Little Ice Age, which was a period of regionally cold conditions between 1650 to 1850, that is thought to have been possibly triggered by a decrease in solar output from the sun. Be that

factors leading to the variability in climate. According to Bréon et.al (2013:894) processes within the climate system is caused by internal variation in climate. These processes are usually measured in decadal to centennial time scales. Climate variability can be caused externally, internally, naturally or by humans. Thus is natural climate variability the variation of the earth’s climate caused by natural factors. The best examples of natural climate variability are the El Niño and La Niña phenomenon’s

particular place.( IPCC Third Assessment Report - Climate Change 2001; editor:A.P.Baede) Climate change is a variation of average weather. There are 2 causes of climate change. The first is human activity which includes deforestation, burning fossil fuels, agriculture, transportation and infrastructure. The second is natural causes which include volcanic eruptions and variations in solar outputs. These causes have negative effect on the natural

becoming overwhelming clear, along with the evidence that it is human induced. Common attempts to debunk climate change and humans causing it have been disproven. These attempts include but are not limited to: Tectonic processes, orbital variations, volcanoes, and solar variability (Dressler and Parsons, 2006). In their writing, Parsons and Dressler prove each of these to not be reasons of

"What if global warming is just a natural cycle?" This argument is, perhaps, one of the most common raised by the average person, rather than someone who makes a career out of denying climate change. Cyclical variations in climate are well-known to the public; we all studied the ice ages in school. However, climate isn 't inherently cyclical. A common misunderstanding of the climate system characterizes it like a pendulum. The planet will warm up to "cancel out" a previous period of cooling, spurred

Ever since the twenty-first century, the injury and menace posed by global climate change to human being has long been acknowledged by public. In the face of global warming, a series of resulting problems inflict a serious threat on the nature environment, which is the material base of the human being depending on. Therefore, climate change is no longer just a discipline problem but also has gradually become a major social problem, which has draw a common concern for us humans. During this, the resulting

global, long-term importance. In the ort-term. El Nino can bring a dry summer for some regions and a wet winter for others; however, over the course of many years, the number of times El Nino conditions occur may decade changes in the global climate. Variations in the behaviour of the weather over long time periods, such as from one century another, are referred to as climate change. Climate itself adjusts from the times of 'ice ages,' hen huge ice sheets covered large areas that are currently ice-free

energy enter Earth’s system. When the sunlight reaches Earth, it can be reflected or absorbed, and that depends on the Earth’s surface and atmosphere; light colors reflect the most sunlight, while dark colors absorb more sunlight. Albedo, the amount of solar radiation reflected from an object or surface, indicates the amount of sunlight reflected as a percentage. Earth has an albedo of about 30%, which means that 70% of the sunlight is absorbed (NRC, 2010). This is important because the sunlight absorbed

The ancient Maya civilisation has generated great interest in many academic scholars and scientists, due to the phenomenon which saw one of the most dramatic civilisation collapses in recorded history, during what has been referred to as the Terminal Classic Period- A.D. ∼700 to 950 (Haug et al, 2003). Interestingly, the ancient civilisation has been characterised by its collapse in the 9th century, perhaps even more so than its remarkable accomplishments, such as: creating vast hierarchical and
