Sufficient Evidence

According to the geological history of the earth, climate change is an integral part of environmental changes that occurred over time. Sufficient evidence is provided of recurrent wet and dry and cold and hot periods due to natural circumstances. Since the industrial revolution human activities increasingly contribute to air pollution by releasing huge volumes of carbon dioxide and other gasses into the atmosphere, so much so that it is generally accepted that increase in global warming the past decades is directly linked to human activities. Observable signs of human induced climate change include increasing average temperatures at many places, melting ice caps in polar areas, rising sea levels on a global scale and coastal disturbances and damages due to storm surges on coastal areas in various countries, also in South Africa. Consensus from a number of hydrological-meteorological circulation models show, for South Africa, a rise in average annual winter and summer temperatures of between 1.5 and 3.0 degrees Centigrade the following number of decades with a strong possibility of an increase in rainfall in the eastern parts and a decrease in rainfall in the western parts. Bigger floods and longer droughts should occur more frequently as well as severe sea onslaught activities along the eastern and south-eastern coastal areas. The net impact of the predictions on the community is negative. There is though other scientists who indicate that no concrete proof of climate change in South Africa exists; including changes with regard to river floods and droughts. According to more beneficial than detrimental. Despite the differences in opinion about the relative contribution of natural and human activities to the present global warming, changes in hydrological and characteristics of floods in several parts of South Africa in the immediate past, necessitate modifications to available models and approaches to flood damage management and control. Flood conditions need to be managed with applicable models. Modifications are furthermore essential as a result of meaningful demographic, social, physical and economic changes in the working and living environments of people and communities.

The Earth

The climate of a region is a representation of long-term weather conditions that prevail there. Over the millions of years of the existence of the atmosphere on the earth, the climate has changed all the time; ice ages have come and gone, and this has been the result of natural causes. Recently (on geological time scales) the human population has expanded—from half a billion in 1600, to 1 billion in 1800, to almost 3 billion in 1940, and it now stands at about 6 billion. The climate may well now be influenced not only as before by natural events but also by human activities. For example, we are producing vast amounts of carbon dioxide by burning fossil fuels, and this is causing the temperature of the earth to rise significantly. If we argue that we should control our activities to preserve this planet as a habitable environment for future generations, we need to have some scientific knowledge of the effects of our present activities on climate. In recent years the evidence has been accumulating that on the time scale of decades there is global warming (i.e., the global annual mean surface temperature is increasing). There is also evidence accumulating that part of this increase is a consequence of human activities. The evidence is largely statistical. Within this trend there are bound to be temporal fluctuations and spatial variations. Moreover, in addition to the increase in temperature, it is reasonable to assume that there is, overall, an increase in evaporation of water from the surface of the earth and that there will be a consequent increase in precipitation. But within this overall scenario there are bound to be local variations; some areas may experience more precipitation, but some areas may experience less precipitation. The effect of climate change on the proneness to drought is therefore not uniform but can be expected to vary from place to place. Therefore, whether one is concerned with considering the relation between climate and proneness to drought from the historical evidence or whether one is trying to use models to predict the effect of future climatic conditions, it is necessary to consider the local spatial variations.

Laws Of Thermodynamics

It is the postulate of the current work that all human activities do add heat to the global environment. The basis used is the concept of thermodynamic entropy and the second law of thermodynamics. It has been discussed and shown that human activities do release heat to the global environment. There is no claim and not the objective in the current work to make any statement about climate change or global warming. It is suggested that all significant human-related activities have been included in the discussion, and hence the proof and deduction. The approach used is in accordance with the manner in which the laws of thermodynamics were derived, which is empirical.

Emission Of Greenhouse Gases

As known to all, the emission of greenhouse gases is mainly caused by human activities. If we could cut down the emission, we could gradually prevent the influence of climate change. Relevant research shows that in the field of energy consumption, the control of CO2 emission is the most effective way to save energy. Thus, reducing the architectural energy consumption is one of the most crucial factors to realize global climate goals. Although more and more scholars prefer to use the word ‘dilemma’ to describe the urgent contradiction between architectural construction and environment, and energy as well, I still want to discuss the influence of global warming on the architecture industry, and explain why it is an opportunity as well.

The Relationship

2019 was Earth's second warmest year since 1850. In 2019 the global mean temperature was cooler than in 2016, but warmer than any other year explicitly measured. Consequently, 2016 is still the warmest year in historical observation history. Year-to-year rankings are likely to reflect natural fluctuations in the short term, but the overall pattern remains consistent with a long-term global warming trend. This would be predicted from global warming caused by greenhouse gases, temperature increase across the globe is broadly spread, impacting almost all areas of land and oceans. Climate change" and "global warming" are often used interchangeably but are of distinct significance. Global warming is the long-term heating of the Earth's climate system observed since the pre-industrial period as a result of human activities, mainly the combustion of fossil fuel, which raises the heat-trapping greenhouse gas levels in the Earth's air. The term is often used interchangeably with the term climate change, as the latter applies to warming caused both humanly and naturally, and the impact it has on our planet. This is most generally calculated as the average increase in global surface temperature on Earth. Carbon dioxide emission is one of the main reasons for global warming. Since the Industrial Revolution, human sources of carbon dioxide emissions have been growing. Human activities such as the burning of oil, coal and gas, as well as deforestation are the primary cause of the increased carbon dioxide concentrations in the atmosphere. In our research, let’s examine the relationship between the amount of carbon dioxide emissions and the GDP/capita in developed and developing countries.

The Yangtze River Basin

Characterized by increasing surface air temperature, global warming has altered the hydrological cycle at global and regional scales. In order to adapt water resources management under the context of global warming, attribution analysis on regional differentiation of water resources in the Yangtze River basin (YRB) was conducted in this study. Meteoro-hydrological variations across the basin were examined for the period 1960–2013, and then a statistic-based method was applied in quantifying the contributions of climate variability and human activities on annual runoff variations in different tributary sub-basins in the YRB. Our observation indicates that both the annual increasing rate and the inter-annual fluctuations of temperature in China and in the YRB were higher than that of the global average since the turn of the century. Climate change analysis indicates that the YRB experienced a hot-wet period during 1994–2002 and a hot-dry period during 2003–2013, since the step change of temperature in 1993. Contributions of climate change and human activities on runoff variations varied spatially in the basin. With reference to the baseline period of 1960–1993, the contribution of climate change played a dominant role in most regions of the basin, especially in those upstream sub-basins. The effect of human activities in the basin was quite complicated, not only its regional differentiation, but also its contribution were opposite during the hot-wet period and the hot-dry period in some sub-basins. The result of this study is helpful in understanding the impacts of climate change and human activities on water resources variation in both temporal and spatial scales.

The Relationship

This paper is focused on the relationship between ozone depletion and environmental climate change. Ozone (O3) depletion and global warming are not directly related to each other but have a common reason as pollutants released into the atmosphere by human activities which alter both phenomenal change. Global warming is incident of accumulation of higher level of carbon dioxide into the atmosphere when hydrocarbons are used to generate electricity to run vehicles. Carbon dioxide spreads around the earth like a cover which is mainly responsible for the absorption of infrared radiation as a heat. Ozone depletion occurs when chlorofluorocarbons (CFCs) and halon (halogen) gases are observed in aerosol. Practically, spray cans and refrigerants are the sources of CFCs. Ozone is available in the stratosphere and absorbs ultraviolet radiaton, which is very harmful to humans, animals and plants. By photochemical reaction ozone molecules are broken down by CFCs and halons, which are the primary substances in the chemical reactions, reducing ozone’s ultraviolet radiation-absorbing capacity.

Impacts Of Climate Change

Sea level rise is one of the impacts of climate change and global warming caused by the increase of human activities leading to the increase of concentration of greenhouse gases in the atmosphere. The impacts of sea level rise itself will be greatly felt by coastal areas in island countries, one of them is Indonesia (specifically the district of Tuban). The purposes of this paper are (1) to indicate that tidal data in Semarang and Tuban (both of them are cities in the northern coast of Java) can be used to estimate the sea level rise in the region through the means of comparison, and (2) to compare sea level rise in MAGICC model and show that sea level trends for Tuban district are consistent with global values. The results shows that the tidal data in Tuban has a higher value than the tidal data in Semarang by a margin of 0.03 m, so the trend of sea level rise in Tuban is y = 0.002x + 0.751, consequently the sea level rise per year is 0.024 m. Comparison of sea level rises between the MSL data of Tuban district with MAGICC model indicates that the sea level trends for Tuban district (local) are consistent with global values, that is, in the year of 2100, the sea level rise will reach 2.64 m while emissions scenario that comes close is the WRE 550 scenario, that is, in the year of 2100, it will reach 2.9 m.

The Impact

Climate change has received considerable media attention in recent years, particularly in terms of the enhanced greenhouse effect and predicted global warming. This paper examines the alternative impact of atmospheric acrosols on global climate in terms of the so-called dust-veil effect, which is associated with global cooling. This volcanic signal is assessed through the application of dust-rating and explosivity indices, and their limitations are emphasized since both schemes ignore the more important sulphur-gas emissions. The paper discusses the causes and evidence of the volcanic signal and emphasizes its moderation by El Nino events. It concludes with a brief analysis of the contributions made by particulate matter released into the lower troposphere from human activities.
