Solar Radiative Flux

Statistical analysis of the number of destructive earthquakes versus global temperature and greenhouse gases revealed very significant correlations. This is a strong indication that the frequent occurrence of major earthquakes had increased earth’s obliquity and induced both global warming and emission of greenhouse gases (GHG) in recent years. It is further shown by a simple model developed here that seismic-induced oceanic pressure could enhance the obliquity leading to increased solar radiative flux on earth. The possible increase in the planetary obliquity was substantiated by the solar radiation model SOLRAD, which simulated an associated increase of absorbed solar radiation. The model also revealed a net poleward gain of solar radiative flux with enhanced obliquity which could be the cause of the observed polar amplification of global warming and climate change. Multiple regression analysis also showed that the sudden obliquity change since 1995 played a major role in the temperature rise and GHG increase, and coincided with the 10 warmest years on record. Climate simulations conducted with the EdGCM also showed that enhanced obliquity causes increased solar radiative flux, increased air and ocean temperature, and decline of ocean ice cover. The enhanced obliquity and absorbed solar radiation could have accelerated the melting of ice sheets and glaciers, exposure and degradation of permafrost regions, increased CO2 respiration fluxes from soil, and forest fires during summer. This study confirmed in several ways that earthquake-pressured obliquity change, and not greenhouse effect, is the major mechanism governing global warming and climate change presently occurring on earth.

Solar Radiative Flux

Statistical analysis of the number of destructive earthquakes versus global temperature and greenhouse gases revealed very significant correlations. The motion of the North Pole, deduced from the geomagnetic polar shift data, is highly correlated with major earthquakes. This is an indication that the frequent occurrence of major earthquakes had increased earth’s obliquity and possibly induced global warming and emission of greenhouse gases. It was shown by a simple model developed here that seismic-induced oceanic force could enhance the obliquity leading to increased solar radiative flux on earth. The increase of the absorbed solar radiation due to polar tilt was also confirmed by SOLRAD model which computed a net gain of solar radiative forcing due to enhanced obliquity. SOLRAD also revealed a poleward gain of solar radiative flux which could have facilitated the observed polar amplification of global warming. Multiple regression analysis also showed that polar shift and solar irradiance played a major role in the temperature rise and CO2 increase in recent years. The analysis showed that obliquity change due to North Pole shift and total solar irradiance accounted for 63.5% and 36.4% respectively, while CO2 changes accounted for 0.1% of the observed global warming. Preliminary simulations conducted with EdGCM climate model also showed that enhanced obliquity increases the absorbed solar radiative flux, surface air and ocean temperatures, and decreases ocean ice cover. This study confirmed in several ways that earthquake-perturbed obliquity change, and not greenhouse effect, is the major mechanism governing the present global warming and climate change problem.

Climate change is of great importance in modern times and global warming is considered as a significant part of climate change. It is proved that human’s emissions such as greenhouse gases are one of the main sources of global warming (IPCC, 2018). Apart from greenhouse gases, there is another kind of matter being released in quantity via emissions from industries and transportations and playing an important role in global warming, which is aerosol. However, atmospheric aerosols have the net effect of cooling towards global warming. In this paper, climate change with respect to global warming is briefly introduced and the role of aerosols in the atmosphere is emphasized. Besides, properties of aerosols including dynamics and thermodynamics of aerosols as well as interactions with solar radiation are concluded. In the end, environmental policies and solutions are discussed. Keywords: Climate change, Global warming, Atmospheric aerosols, Particulate matter, Radiation, Environmental policy.

The Impact

<div> <p>In recent times we have often received news such as about melting glaciers, sudden and torrential rain, storms, increased atmospheric temperatures, and forest fires. We have also observed some of these phenomena in our immediate vicinity. There is a frequently used expression among the public, 'the seasons are shifting'. </p> <p>Students have asked the reasons why these changes have been occurring and what about changes between the past and present. In order to understand these changes we all know that they need to understand global warming in the first place. To help them with this as an science teacher I have guided them to be capable of using experimental methods within project-based learning approaches. First they did preliminary literature surveys and then they designed an experiment. In the experiment, they tested the hypothesis that the water inside the bell JAR, which is coated with black cardboard, heats up more than the transparent one. In this way they began to investigate climate change due to greenhouse gases. </p> <p>In the experiment, two bell glasses were used to represent the atmosphere layers. One was intermittently covered with pieces cut out of black cardboard. Black cardboard was used to represent the greenhouse gas due since the black colour absorbs light. Two beakers of the same size were used, filled with water. A thermometer was placed inside and bell jars were turned upside down and put over the beakers. The two thermometers were used to measure the water temperature inside the beakers. </p> <p>The first apparatus is the control group (inside uncovered). The second apparatus is the experimental group (covered with independent black cardboard). In the experimental and observation stage, the independent variable is the bell jar; the dependent variable is the water temperature. The constant variables are the size of the jar, the size of the beaker, the amount of water and the ambient conditions. </p> <p>Having set up the apparatus, the initial temperature of water was measured and recorded. Students carried out the experiment on a sunny day by placing the apparatus in a sun-covered field. They recorded the data in the tables they completed periodically. Then they shared the results with participants at the science festival. </p> <p>In this way they began to investigate the impact of greenhouse gases on climate change.</p> </div>

Temperature Oscillations

Global warming has potentially catastrophic impacts in Amazonia, while at the same time maintenance of the Amazon forest offers one of the most valuable and cost-effective options for mitigating climate change. We know that the El Niño phenomenon, caused by temperature oscillations of surface water in the Pacific, has serious impacts in Amazonia, causing droughts and forest fires (as in 1997-1998). Temperature oscillations in the Atlantic also provoke severe droughts (as in 2005). We also know that Amazonian trees die both from fires and from water stress under hot, dry conditions. In addition, water recycled through the forest provides rainfall that maintains climatic conditions appropriate for tropical forest, especially in the dry season. What we need to know quickly, through intensified research, includes progress in representing El Niño and the Atlantic oscillations in climatic models, representation of biotic feedbacks in models used for decision-making about global warming, and narrowing the range of estimating climate sensitivity to reduce uncertainty about the probability of very severe impacts. Items that need to be negotiated include the definition of "dangerous" climate change, with the corresponding maximum levels of greenhouse gases in the atmosphere. Mitigation of global warming must include maintaining the Amazon forest, which has benefits for combating global warming from two separate roles: cutting the flow the emissions of carbon each year from the rapid pace of deforestation, and avoiding emission of the stock of carbon in the remaining forest that can be released by various ways, including climate change itself. Barriers to rewarding forest maintenance include the need for financial rewards for both of these roles. Other needs are for continued reduction of uncertainty regarding emissions and deforestation processes, as well as agreement on the basis of carbon accounting. As one of the countries most subject to impacts of climate change, Brazil must assume the leadership in fighting global warming.

Is Implementation

This chapter outlines the challenge facing us. The Paris Agreement sets a target maximum of 2°C global warming and a preferred limit of 1.5°C. Yet, the subsequent combined national pledges for emission reduction suffice only for limiting warming to roughly 3°C. And because most nations are falling considerably short of meeting their pledges, even greater warming may become locked in. Something more drastic and wide-ranging is needed: a multi-pronged strategy. These different prongs to the climate-change solution are introduced in this chapter and explored one by one in the following chapters. First is rapid, massive reduction of greenhouse gas emissions. Second is implementation of ways to remove greenhouse gases from the atmosphere. Third may be increasing the reflectivity of Earth to incoming sunlight, to cool certain places down more rapidly. In addition, we need to protect ourselves from climate-change impacts that have already become inevitable.

‘Evidence for climate change’ considers both past and recent climate change through changes in temperature, precipitation, and relative global sea level to show that significant changes in climate have been recorded. These include a 0.85°Celsius (C) increase in average global temperatures over the last 150 years, sea-level rise of over 20 cm, significant shifts in the seasonality and intensities of precipitation, changing weather patterns, and significant retreat of Arctic sea ice and nearly all continental glaciers. The IPCC 2013 report states that the evidence for global warming is unequivocal and that there is very high confidence that this warming is due to human emissions of greenhouse gases.

CO2 is the most frequently implicated in global warming among the various greenhouse gases associated with climate change. Chinese government has been taking serious measures to control energy consumption to reduce CO2 emissions. This study applies the grey forecasting model to estimate future CO2 emissions and carbon intensity in Shijiazhuang from 2010 until 2020. Forecasts of CO2 emissions in this study show that the average residual error of the GM(1, 1) is below 1.5%. The average increasing rate of CO2 emissions will be about 6.71%; and the carbon intensity will be 2.10 tons/104GDP until year 2020. If the GDP of Shijiazhuang city can be quadruple, the carbon intensity will be half to the 2005 levels until 2020. The findings of this study provide a valuable reference with which the Shijiazhuang government can formulate measures to reduce CO2 emissions by curbing the unnecessary the consumption of energy.

Emission Of Greenhouse Gases

When a decision-maker faces a choice between alternatives of action in a situation of uncertainty, one speaks of a “game against Nature” when he/she faces no interaction with another player or group. In the process of global warming, mankind is the one player facing two alternatives: resilience or precaution. Not knowing fully the consequences of the increase in the emission of greenhouse gases on climate change or the implications of climate change for biological and social system, what action to take? If there were a global benevolent rule, he/she may decide to avoid the worst outcome. But global ecological policy-making requires the coordination among a large number of players, which open up the possibility of reneging as well as carries heavy transaction costs.
