Global Total Temperature Growth

Research Paper Lepei Feng Frank Sterns UW-1020 April 10th, 2019 Research Paper Introduction: Increasing data suggest that human activity has been one of the causes of the rise in the air over the past century. Media coverage of extreme weather events can raise awareness of the risks of climate change. The actual measurement of global temperature growth shows that the trend of global total temperature growth is undeniable. In recent years, the temperature has been rising sharply. Of the 25 hottest years measured, 20 belonged to the last 25 years. Heat waves have begun to appear, and scientists believe they will be more frequent if global warming is not addressed. There is abundant evidence that the concentration of carbon dioxide in the atmosphere has increased from 280 micromol/mol before the Industrial Revolution to 350 micromol/mol in the early 1990s due to the influence of human activities. Correspondingly, the annual average temperature of the earth's surface has also risen by 0.6 degrees centuries. Therefore, there is no doubt that the greenhouse effect caused by human activities is increasing. Many scientists firmly believe that even at the current rate of CO2 emissions, the concentration of carbon dioxide in the atmosphere will double by the middle and late of this century. Therefore, it is certain that the global climate pattern will change in the next 100 years. At present, although the predictions of future climate change by various atmospheric circulation models (GCMs) are different, the overall trend of future climate change predicted by GCMs is the same. Looking at the predicted results of future climate change after the doubling of atmospheric carbon dioxide concentration, we can conclude the following; * The global average temperature will rise by 1.5-4.5 degree Celsius, and the global climate zone will shift to the poles to a certain extent. * The increase of minimum temperature is larger than that of maximum temperature; the increase of night temperature is larger than that of daytime temperature, and the increase in winter temperature is larger than that of daytime temperature. Summer warming is evident. * Global rainfall has increased in general, but the pattern of global rainfall will change. Rainfall may vary greatly according to different regions and seasons (e.g., coastal areas will increase, while inland areas will not change or even decrease). * Evapotranspiration will cause much more water loss than rainfall increase, so the mid-latitudes. Summer drought in inland areas will increase significantly. As future climate change may have a huge impact on the global ecological environment, society, and economy, this is the main reason why people pay close attention to climate change. This paper discusses the destruction of ecosystems caused by climate change and the reasons for the rising global temperature, as well as the solutions that governments and communities can put forward to solve this global ecological problem. However, the fact that global climate risks still have a lot of difficulties, it is also critical to address this fact. In this article, we will discuss the obstacles we have to overcome to help solve global climate problems in the context of global warming. Potentially dire effects, coupled with global climate change, are attracting increasing attention from scientists, elected officials and the public At present, more than 7 billion people live on this planet, yet, depending on future fertility and mortality rates, the future population may begin to decline. Human activities, mainly the combustion of fossil fuels and land use/cover changes, are changing the concentration of atmospheric components, the characteristics of ground absorption and radiation energy. Carolin et al., (2019), established that "based on the latest evidence and taking into account uncertainty, the warming observed over the past 50 years may be largely due to the increase in greenhouse gas concentrations". The concentration of atmospheric CO2 has increased from 280+10 ppmv in 1750 to 367 ppmv in 1999. The current level of atmospheric CO2 concentration is unprecedented in the past 420,000 years. At present, the global average CO2 growth rate is 1.5-1.8 ppmv/a. Based on this, it is predicted that the atmospheric CO2 concentration will reach 600 ppmv in 2030 and 650-700 ppmv at the end of the 21st century. A large number of observations and evidence show that the global surface temperature has risen by 0.6 + 0.2-degree Celsius in the past 140 years (Izdebski et al., 2016). The 20th century is the warmest century in the past millennium, and the 1990s are the warmest decade in the past millennium, and this warming trend is continuing. Future climate change mainly includes climate warming, changes in precipitation and types of precipitation, sea level rise and changes in frequency and intensity of some extreme weather events. For climate change, the consequences of rising temperatures may increase from 1.5 degrees Celsius to 3 degrees Celsius. The decline in population is less dependent on the number of disaster relief efforts. Veronica and other researchers link these two global trends in a PNAS paper on population growth and the impact of population ethics on mitigation policies (Parmesan, 2014, July 08). When asked about different population scenarios, they also proposed and explored how to change mitigation policies, and vice versa. In this article, there is no doubt that the answer depends on a fairly reasonable choice: the goal is to maximize the total utility (TU) or the average utility (AU). In the context of global warming, human safety and mental health may also be affected. There are few studies on this subject. After reading many articles, I found that short-term exposure to tropical cyclones in more extreme weather, years of warming and tropical cyclones associated with human mental health. For insects and animals, when global warming occurs, insects can change their body temperature to adapt to the outside world. With the increase in carbon dioxide and global warming, our challenge is to predict ecosystem responses, which include a set of interacting populations in abiotic fields such as temperature, humidity, and biogeochemistry. Thermal performance theory has become a powerful way to understand this biological change. According to the biological structure characteristics, the thermal energy distribution also has the thermal gradient to the environment. In this case, our ecological evolution can be transformed from reproductive growth to survival. The basic logic and theory are that temperature limits the number and distribution of humans and other creatures. To explore this theory, we need to be aware of the importance of natural history and the diversity of ways in which organisms experience temperature. Climate change has many adverse impacts on ecosystems. First of all, the spatial distribution of species has changed. The geographical distribution of species moves to high latitudes and altitudes, and the distribution of some species is reduced or fragmented. Fragmentation may hinder the exchange of information such as specific genes. Second, changes in population characteristics. It is mainly reflected in the changes in the interactions between organisms. The mismatch between food supply and demand peaks (e.g., animal litter time) and the fact that the behavior of species formerly occurring at the same time no longer occurs at the same time lead to changes in the intermediate relationship, which will hinder the growth of individuals and populations. This eventually leads to the reduction of population size and the disappearance of endemic species, which will affect the structure, function, and development of species and ecosystems. Secondly, individual life events change. Phenological events of species change, some spring events (such as the time when a ...
