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, co...
