Abstract Climate Change due to excessive buildup of greenhouse gasses in the atmosphere from hydrocarbon combustion is one explanation (NASA greenhouse effect) for the Earth’s temperature increase since 1850. If this is true, then eliminating fossil fuel use is the only way to preserve our planet. However, there is another explanation for Global Warming/Climate Change that leads to the opposite conclusion – hydrocarbon energy will be needed well into the future to cope with future, excessively hot and cold temperature cycles. This paper will show that the Global Warming/Climate Change underway on Earth today is a totally natural occurrence with solid scientific and historical support. The Earth is currently in the upswing part of its normal temperature cycle. Very warm (Medieval Warming) and very cold (Little Ice Age) cycles have been historically documented on Earth for at least the last 3,000 years. This cyclicity has a repeated period of about every 1,500 years (Singer 2008). This explanation for the Earth’s temperature increases since 1850 is captured in a mathematical model called the Cyclical Sine Model. This model fits past climate cycles, measured temperatures since 1850, and correlates closely with the cyclicity of Bond Atlantic Drift Ice Cycles (Bond 1997), the Atlantic Multidecadal Oscillation (NASA AMO), and the Pacific Decadal Oscillation (NASA PDO). This model also quantitively explains the time span 1945-1975 when an impending ice age was feared (Time Magazine 1974). The Cyclical Sine Model is the best explanation for the Earth’s recent temperature increases.

Model Explanation

Abstract This paper will show that the global warming/climate change underway on Earth today is a totally natural occurrence with solid scientific and historical support. The Earth is currently in the upswing part of its normal temperature cycle. Very warm (Medieval Warming) and very cold (Little Ice Age) cycles have been historically documented on Earth for at least the last 3,000 years. This cyclicity has a repeated period of approximately every 1,500 years [1]. The explanation for the Earth’s temperature increases since 1850 is captured in a mathematical model called the Cyclical Sine Model. This model fits past climate cycles, measured temperatures since 1850, and correlates closely with the thousand year cyclicity of solar activity from 14C/12C ratio studies [2], and Bond [3] Atlantic drift ice cycles. This model also agrees with sunspot history, the Atlantic Multidecadal Oscillation, and the Pacific Decadal Oscillation. In addition, this model quantitively explains the time span 1945-1975 when an impending ice age was feared [4]. Earth temperatures are controlled by three solar cycles of approximately 1,000, 70, and 11 years. The Cyclical Sine Model is the best explanation for the Earth’s recent temperature increases.

Abstract We are in a period of relatively rapid climate change. This poses challenges for individual species and threatens the ecosystem services that humanity relies upon. Temperature is a key stressor. In a warming climate, individual organisms may be able to shift their thermal optima through phenotypic plasticity. However, such plasticity is unlikely to be sufficient over the coming centuries. Resilience to warming will also depend on how fast the distribution of traits that define a species can adapt through other methods, in particular through redistribution of the abundance of variants within the population and through genetic evolution. In this paper, we use a simple theoretical ‘trait diffusion’ model to explore how the resilience of a given species to climate change depends on the initial trait diversity (biodiversity), the trait diffusion rate (mutation rate), and the lifetime of the organism. We estimate theoretical dangerous rates of continuous global warming that would exceed the ability of a species to adapt through trait diffusion, and therefore lead to a collapse in the overall productivity of the species. As the rate of adaptation through intraspecies competition and genetic evolution decreases with species lifetime, we find critical rates of change that also depend fundamentally on lifetime. Dangerous rates of warming vary from 1°C per lifetime (at low trait diffusion rate) to 8°C per lifetime (at high trait diffusion rate). We conclude that rapid climate change is liable to favour short-lived organisms (e.g. microbes) rather than longer-lived organisms (e.g. trees).

Low Global Warming Potential

The most commonly used refrigerants are potent greenhouse gasses that can contribute to climate change. Hydro-Fluoro-Olefins are low Global Warming Potential fluids. A summary of our experimental research activity on the thermodynamic properties of two environmentally friendly Hydro-Fluoro-Olefins, namely R1234yf and R1234ze(E), is reported. In particular, the measurements were performed with an isochoric apparatus and the apparatus specifically built to reach temperatures down to about 100 K. The data elaboration confirms the validity of the choice and that R1234yf and R1234ze(E) can be adopted in many domestic applications. Moreover, considering the reduction of the flammability issues of R1234yf and R1234ze(E), the properties of binary systems containing these fluids and carbon dioxide were analyzed. The presented mixtures could be very interesting for low-temperature applications such as cascade cycles.

Impacts Of Climate Change

Climate change is the single biggest environmental issue facing the world today. It has become a great challenge to our generation and its impact is felt in almost every society in the world. Nigeria is one of the most vulnerable countries in Africa. Nigeria as a developing nation with a population of about 200 million people is likely to be adversely impacted by climate change due to its vulnerability and low coping capabilities. Climate change is evidently linked to human actions, and in particular from the burning of fossil fuels and changes in global patterns of land use. The impacts of human activities, as well as those of natural phenomena on global warming, climate change, and the environment, were presented and discussed. Various manifestations of its impact are evident in Nigeria, which includes temperature rise, increase in draught, and scarcity of food instigated by irregularities in rainfall, over flooding, and so on. This paper examines the concepts of global warming and climate change; its impact on the Nigeria ecosystems. It highlights the climate change-related risks and hazards the nation could face if best practices are not employed to prevent and mitigate its impact. Two sets of measures have been advocated for confronting climate change, these are mitigation and adaptation measures. The review explores possible adaptation strategies that are required to respond to the climatic variations and suggests ways that these adaptation strategies can be implemented.

Abstract. The response of the climate system to external forcing has become an item of prime interest in the context of global warming, especially with respect to the rate of melting land-based ice masses. The deep-sea record of ice-age climate change has been useful in assessing the sensitivity of the climate system to such forcing, notably to orbital forcing, which is well-known for the last several million years. When comparing response and forcing, one finds that sensitivity varies greatly through time, apparently in dependence on the state of the system. The changing stability of ice masses presumably is the underlying cause for the changing state of the system. A buildup of vulnerable ice masses within the latest Tertiary, when going into the ice ages, is conjectured to cause a stepwise increase of climate variability since the early Pliocene.

This article examines global warming using the narrative genre model of risk evaluation. The narrative genre model of risk evaluation offers a systematic and comparative way of looking at the form and structure of storytelling and its consequences for human action. It is based on a number of claims, for example: uncertain events and real world facts are “clues”; we can see things as low mimetic, romantic, tragic, or apocalyptic; binary oppositions play a role as building blocks for wider storytelling activity. The article first provides a background on the issues of global warming, climate change, and greenhouse gas emissions before discussing the rise and growing acceptance of the apocalyptic genre as part of the discourse on global warming. It then considers the critique of apocalypticism, arguing that it is not only a bad genre guess that can be mocked, but also a hegemonic and anti-democratic force. It concludes with a commentary on how the narration of global warming is taking place at two levels.
