Climate Change and Global Warming Humanity Greatest Threat
Climate change and global warming are real. The world’s climate is changing, and the changes will have an enormous impact on the planet’s people, ecosystems, cities, and energy use. Average global air temperatures are already 1.5 degrees higher than they were at the start of the 20th century, and have risen about 1 degree over just the last 30 years. Scientists have discover some of the causes for these drastic changes. Greenhouse gases, according to scientists are the main culprit for climate changes. Also, humanity force is another cause for the drastic climate changes we are facing today. Finally, solar variability accounts for most or all of the warming in the late twentieth century …show more content…
The amount of warming contributed by natural forces. Furthermore, according to new studies deforestation is a contributor to climate change, global warming, and is often cited as one of the major causes of the enhanced greenhouse effect. Tropical deforestation is responsible for some of the world greenhouse gas emissions. Also, anyone living in or near a large city knows that jets often leave trails behind them, called contrails. Composed of water vapor, they precipitate the creation of low clouds that have a net warming effect. According to a study, contrails in the U.S. may cause a net warming of the surface rivaling that of greenhouse gases and in certain regions, contrails already may contribute as much as the present anthropogenic CO2 forcing on climate. Furthermore, cities tend to be warmer than the suburbs, and the suburbs warmer than rural areas, because they have greater concentrations of energy-producing machines and vehicles and large amounts of concrete, asphalt, and other building and road materials that absorb solar energy and then re-emit thermal energy. These urban heat island effects have been documented by many authors. Finally, studies concluded that the real global mean surface temperature trend is very likely to be considerably to higher temperatures caused by urban heat islands to rising atmospheric CO2 …show more content…
Active mixing of gases on the near-surface of the Sun, denoted by changes in the number of sunspots, causes changes in the radiant energy emitted by the sun. There is evidence that Earth’s climate warms and cools in synchrony with these cycles. Solar flares, which are bursts of energetic particles and radiation from the surface of the Sun, can work additively in resent climate and global changes. These events cause an outflowing of charged particles called solar winds. Solar winds will reach Earth and its atmosphere, allowing temperature to increase. Also, a group of scientists believes small changes in solar radiation entering Earth’s atmosphere are amplified by positive feedbacks involving the transfer of energy between the equator and the Arctic via wind patterns and oceans.Solar variability provoking changes in North Atlantic deep water formation that alter the thermohaline circulation of the global ocean by the rapid increase in temperatures. Finally, scientists reveal a three-part mechanism whereby the variation in total solar irradiance (TSI) affects Arctic temperatures by modulating the thermohaline circulation (THC), the InterTropical Convergence Zone (ITCZ) rainbelt and tropical Atlantic ocean conditions, and the intensity of the wind-driven subtropical and subpolar gyre circulation, the ring-like system of ocean currents rotating clockwise in the Northern Hemisphere
