Joud El Dweiri Ms.Maleha 11B English May 11, 2017 Climate change; a hoax or the dreadful truth? Climate change is a shift in global weather patterns including temperature, precipitation, humidity, and wind. Climate patterns play an important role in forming natural ecosystems and human economies. This subject has been a topic of discussion for many years, but not for the reason one might think. The argument is not about how to help the Earth or what we are doing wrong, but about if climate change even exists.
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.
Introduction Climate change has become a major issue throughout the world lately. The rate of climate change is still increasing and more people are becoming aware of this undeniable fact. The shifts that are being observed in phenology, i.e. life cycle events of plants and animals could be explained by climate change. Individuals can change their phenotype in response to different environmental conditions through a mechanism called phenotypic plasticity.
Climate change is and has been an issue since long time ago. Evolution is imminent and therefore, changes in the ecosystem are included. Even though it is natural, these changes have been accelerated by humans’ actions along the years, and now the effects are being spread among the population. In the last 13 decades, the world has heated up by approximately 0.85 C. Each of the last 3 decades have been successively warmer than the previous one since. According to the Center for Disease Control (CDC) the health effects of climate change include increased respiratory and cardiovascular disease, injuries and premature deaths complement to extreme weather crisis.
Every year in a specific location the climate is different due to the fact that it changes, some years may have a below average rainfall while other years may have an average or above average rainfall. Climate change is credited to both natural variability and human activities. The variation in climate parameters is generally attributed to natural causes but because of changes in the earth's climate since the pre-industrial era some of these changes are now considered attributable to human activities. Natural climate variability and Anthropogenic Climate Change have similar aspects but they can be distinguished from each other as climate refers to the average weather for any given area as it defines the typical weather conditions on long term
Climate changes affect the normal climate conditions that we are familiar to. Warmer average temperatures leads to hotter days as well as more frequent and longer heat waves. This can increase the number of heat-related illnesses and deaths. Changes in temperature, and extreme events could enhance the spread of some diseases. The increasing in the frequency and severity of extreme weather events could increase the risk of dangerous floods, stronger earthquakes, typhoons and other direct threats to people and property as well as the concentrations of unhealthy air and water pollutants.
Climate change affects every living entity on Earth. Climate change can increase or decrease rainfall and temperature. It can cause animals to breed and migrate earlier. It affects the seasons. Climate change can influence crop yields and affect ecosystems.
It also impacts surface runoff and groundwater recharge rates. The dangerousness of these impacts will range geographically. Climate models also said that there will be an increase in the intensity, wind speed, and precipitation associated with tropical cyclones and hurricanes, due to warmer ocean temperatures. However, it remains unclear how warmer ocean temperatures will affect the frequency of these extreme weather events. An increase in the intensity of these storms will affect coastal utilities
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.
Extreme in climate change can have an impact on floods and droughts which will often occur in some areas with a different time. The impact on flooding leads to high water distribution resulting in poor water quality. In this case, the need for climate adaptation for preparing all the aspects that will happen because if the climate leads to excessive flooding, we are required to increase the additional storage capacity to hold all of the excess water that occurs. As with the drought, as a result of the extreme climate makes the quality of water that should be accessible easily become difficult to obtain. Temperature rising also makes demands on the supply of water for irrigation has also increased.
