Climate change means the exchange of heat and mass between land, ocean, ice sheets and atmosphere. The climate slowly changes in its nature but if these changes happen quickly, this can cause severe problems on living organisms and non-living organisms on earth. The rapid change in climate causes increasing amounts of CO2 which cause an increase in temperature. This causes a rise in sea level by melting ice sheets. The global warming also causes harmful effects on the biomass of the ocean’s water because it depletes the quality.
For example; the growth of coral reefs grows between 73° and 84° Fahrenheit, but global warming causes an increase the average temperature of the oceans and will then decrease the rate of growth of the coral reefs. “Every coral reef on Earth could be wiped out within decades due to rising sea surface temperatures and acidic waters caused by climate change and pollution” (Childs). If we can’t understand the rapid climate changes at its present, we won’t handle the problems occurring in the future by the rapid changes in climate.
Climate change cause variation in environmental condition. These variations cause organisms to express different traits. For example, many organisms respond to warmer weather by reproducing earlier but this early reproduction is caused by evolutionary change. This variation also causes many species to have shifted their ranges in response to this small temperature difference. Some species evolved by a change in gene frequency in the population due to global warming. (Davies, 2019). Climate is an important factor that affects the environment.
It makes the living conditions of the region and it is the reason we have regions of different weather conditions. For example, we experience a chill climate in one region and hot weather in the other. This can affect the health of a person when we go from one region to another because it takes time to adapt to a change of climate.
Global climate change impacts intraspecific genetics. Intraspecific variation is the basic foundation of change in evolution and forms the basic level of biodiversity. Genetic variations, as well as phenotypic effects, is important for the individual’s fitness level. This results in high heterozygosity levels, as the deleterious mutations are counterbalances. “Changes in climate affect air quality by perturbing ventilation rates (wind speed, mixing depth, convection, frontal passages), precipitation scavenging, dry deposition, chemical production and loss rates, natural emissions, and background concentrations” (Jacob). When there is an increase in the stress resistance of a population, there is also an increase in the adaptive potential of the same population, which increases the genetic diversity of the population, and if this is lost, it may affect a population.
Climate change is important from an ecological perspective since with changes in climate, there are changes in the physiological characteristics of species. These changes in the physiological characteristics give rise to unique traits to a particular species, which are found only in a particular area. This leads to variation in the species. With the variations in species, there are variations in the behavioral aspects of these species along with the variations in the food habits of these organisms (Davies, 2019). Changes occur in the blooming and reproduction of organisms. Due to geographical isolation and differences in the climate of a species, ecological diversity and biodiversity also transpire. As there is an increase in the different types of organisms with different types of animals, there is the maintenance of evolution. Hence, differences in climate are important for both ecology and evolution.
As we all know, Earth is covered with various gases which make up our atmosphere. The ozone is one that protects us from harmful UV rays, but due to emissions, this layer is being depleted. Ozone depletion is a diverse phenomenon than climate change. This is because climate change occurs by excessive emission of greenhouse gases whereas, greenhouse gas is not the cause for ozone layer depletion. The ozone layer depletion occurs due to an increase in gases like CFC. These gases mainly release from cold storage. Ozone depletion can be controlled because here we must decrease the use of some things like cold storage etc. But climate change is really hard work to control.
The main factors for climate change are deforestation, industrialization, automobiles, etc. Due to this, the greenhouse gas concentration increases. “But every day we tiny human beings drive cars; watch television; turn on lamps; heat or cool our houses and offices; eat food transported to us by planes, ships, and trucks; clear or burn forests; and behave in countless other ways that directly or indirectly release greenhouse gases into the air. Together, we humans emitted eight billion metric tons of carbon to our planet’s atmosphere in 2007 alone” (Thompson). Those gases include CO2, CH4, water vapor, etc. These gases trap the terrestrial radiation from the earth’s surface and don’t allow them to go to the outer space. That’s why the lower atmosphere gets heated up and that will cause global warming. This is a serious issue throughout the world. We must be careful about it.
Understanding the possible risks from climate change and the impacts is a crucial part in evolving the ability of society to handle with changes in the Earth structure. Better scientific understanding and the ability to simulate the impacts of climate change would help politicians and researchers with an inclusive risk assessment. Cautious and attentive monitoring with scientific understanding of the climate system would help our society anticipate changes before they arise.
