Scientists have studies Earth's climate changes for decades, by analyzing many indirect measures of climate such as ice cores, tree rings, glacier lengths, pollen remains, and ocean sediments, as well as by studying the change in Earth's orbit around the sun. This study shows the climate system changes over time over a full range time scales. However, before the Industrial Revolution in the 1700s can be explained climate change by natural causes, such as changes in solar energy, volcanic eruptions, and natural changes in greenhouse gas concentrations. Recent climate changes cannot be explained by natural causes alone. The study indicates that natural causes are not only influenced our climate change in the 21st century.
Prior to the industrial revolution, non-anthropogenic variables were leading roles in climate change but has quickly changed as anthropogenic activities play the leading role in climate change today. Although climate has been changing for decades it has been a recent change in causes that allows climate change to worsen as time goes by. Climate is the average that stands consistent for a long time in an area of precipitation, temperature, atmospheric circulation and atmospheric chemistry. Climate can be affected and changed by man forced and unforced factors. These include volcanic forcing, solar forcing, solar variability and the industrial chemicals.
Climate change can be defined as the long-term variations in atmospheric temperature, precipitation and weather patterns, and the main culprit for this drastic change is Global warming. Which is thought to be man-made. However over the course of history, throughout these 6 billion years the death has had these drastic climatic variation, for which natural factors had been held responsible. However after the Onset of the industrial revolution there has been fundamental change in the nature of the atmospheric system. The earths climate is driven by a continuous flow of energy from the sun.
Furthermore, climate change results in increasingly extreme hurricanes, which causes detrimental flooding, and is also damaging to the economy in the United States. Temperatures are the highest they have been in over three million years; these temperatures are projected to continue to climb over the next several years (Weeks). What does this have to do with hurricanes? There are many ways that climate change effects the intensity of hurricanes. The first key factor is the higher temperatures that cause the ocean to get warmer.
Rainfall prediction is necessary to determine how much of the moisture is available for agriculture and how much of them have been run off to the rivers and streams. However, in excess rainfall may cause damages to agriculture moisture which may be carried out by the rainfall to the streams or rivers. As a result of which floods from the rivers and streams may cause damages to roads, and loss of various sediment and chemicals. Observation of rainfall is needed to know the amount of moisture present in soil, drought and flood conditions. Effective and accurate prediction of rainfall is necessary to prepare for floods and agriculture.
Rainfall analysis has been of great concern during the past century because of the attention given to global climate change by the scientific community. Analysis of variation of rainfall and its attendant in the ecosystem is vital especially in environment where agriculture serve as the major occupation. The aim of this present study is to analyze the characteristics of rainfall in the Northeastern Nigeria using data recorded between 1985 and 2014 at Nigerian Meteorological Agency (NIMET) oshodi, Lagos state Nigeria to detect potential trends and assessing their significance. The data were subjected to statistical analysis using measures of central tendency such as mean, mean deviation and median, and measures of dispersion such as range, variance,
Natural climate change can be divided into two sections, long-term and short term. One of the long term changes is continental drift. Our continents shifted over time and moved over the surface of the Earth over millions of years to what our continents look like today, as seen in Figure 1. (“Causes of Climate Change”, Edgar). Figure 1: Continental Drift At the Permian and Triassic eras, we had ‘supercontinents’.
During the Eighties and Nineties, the scientific community was divided about the phenomenon of climate change. While it was clear that the planet was getting warmer and that other changes were happening, like rising sea levels and altered rainfall patterns, and that the massive increase in global use of the so-called “fossil fuels” — coal, oil and gas — was changing the amount of carbon dioxide in the air, some scientists were cautious in accepting that human energy use was actually causing the changes that were being observed. As more research has been done, it has become clearer that changes to the global climate have not just followed the increasing human use of fossil fuels but are being caused by that process. The science has now been refined to the point where there is no legitimate dispute about the human influence on climate. That does not mean that the debate is over.
Those that disagree with the idea that climate change can have disastrous effects, support their assertion by using the fact that global climate change is not a new occurrence. While this is true, it is not the fact that global climate change is happening that scares people it is the rate at which it is occurring that elicits such a reaction. Ancient evidence of climate change can be “found in tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks.”(NASA). It is within this evidence that scientists were able to conclude that the rate at which “current warming is occurring [is] roughly ten times faster than the average rate of ice-age-recovery warming” (NASA). As a result of this animals and humans alike have not been allowed the time to adapt to the new climate conditions.
Oceans rising, temperatures vary, record level floods, historic droughts, tsunamis, and devastating hurricanes; BOOM! The Earth has gone wild. Scientific evidence suggests that these changes are due to climate change. Climate change is an alteration in the usual temperatures, and weather of a region. The signs that climate change affects our one and only earth clearly show up in the oceans and atmosphere.
