Impacts Of Climate Change

Science is an organized enterprise of inquiry which tries to tie together multiple strands of evidence to craft coherent explanations for disparate patterns in the natural world. Philosophers call this enterprise “inference towards the best explanation”. Such inferences at times depend upon detailed quantitative models, but at times one can rely upon the confluence of multiple strands of qualitative evidence. Humans are having unquestionable influences upon many aspects of the earth system at present, on land, in freshwater systems, and indeed the ocean, including devastating impacts on biodiversity. There are many patterns in the world at present – shrinking glaciers, shifting seasonal patterns in species’ life histories, and altered spatial distributions – which point to the signal of climate change, independent of the details of quantitative climate models. Yet, there are many other factors at play, often confounding clear assessment of the specific role of climate change in observed changes in the world. A deeper synoptic understanding of the drivers and impacts of climate change would be incredibly valuable and is urgently needed, even if in the end (though this seems increasingly unlikely) anthropogenic drivers were not the main factor underlying observed climate change.

Este ensaio traz à tona questões intrigantes e dúvidas que permeiam as pesquisas voltadas às mudanças climáticas globais, enfatizando as discordâncias existentes entre as distintas correntes de cientistas e os prognósticos elaborados pelos modelos de previsão do clima. Para tanto, tomou-se por base as teorias propagadas por alarmistas e céticos, bem como o prognóstico do Painel Intergovernamental sobre as Mudanças Climáticas (IPCC) de 2007. O ensaio se baseou na análise de livros, relatórios técnicos e artigos científicos, além da interpretação dos gráficos contidos nos mesmos. Os resultados mostraram que sempre houve variação na temperatura da atmosfera, mesmo antes do surgimento do homem e em níveis bem mais elevados do que os atuais. Contudo, alarmistas e céticos concordam que a Terra passou por um aquecimento de cerca de 0,6ºC no século XX, havendo divergência no que diz respeito às causas desse aquecimento, suas consequências, e se ele ainda está ocorrendo. Entretanto, um aspecto que põe em xeque a confiabilidade de ambas as correntes diz respeito ao problema da previsão, pois são muitos os fatores e elementos envolvidos na complexidade do sistema climático, tornando, assim, previsões climáticas exatas praticamente impossíveis, e deixando o debate, até o momento, no campo das suposições. Abstract DISCUSSIONS ABOUT GLOBAL CLIMATE CHANGES: THE ALARMISTS, THE SKEPTICS AND CLIMATE FORECAST MODELS This paper aims to discuss difficult questions and doubts about researches regarding global climate change, showing discordances about what different scientific groups and the forecasts elaborated by forecasting climate models. Therefore, we take for basis the theories formulated by the two scientific groups: the alarmists and skeptics, and the prognostic showed by the Intergovernmental Panel of Climate Change (IPCC), 2007. This work was based in a research of books, technical documents and scientific papers, and the interpretation of graphs and data within these works. The results showed that oscillating temperatures always existed in the Earth’s atmosphere before human existence and the oscillation was larger than today. However, alarmists and skeptics believe that the earth atmosphere’s temperature elevated by approximated 0.6º C in the XX century, but there is a big divergence about the causes that rise and the consequences. Finally, an issue that questions the reliability of both groups, concerns the problem of forecast mainly because there are many factors and elements involved in the complexity of climate system thus making accurate climate predictions virtually impossible and leaving the debate so far, in the field of assumptions.

Climatic Characteristics

In order to discuss climate change and our role, this literature review was developed. The term climate change, climate change or climate change refers to global-scale climate change or Earth's regional climates over time. These variations refer to changes in temperature, precipitation, cloudiness and other climatic phenomena in relation to historical averages. Such variations can alter climatic characteristics in a way to change their didactic classification. These changes can be caused by processes internal to the Earth-atmosphere system, by external forces, or by the result of human activity. Therefore, it is understood that climate change can be either an effect of natural processes or arising from human action and so one should keep in mind what kind of climate change is being referred to.

Defining the term of climate, we investigate the role of natural causes and effects of human activities in climate change. The temperature of the Earth is determined by the balance between the amount of radiation energy received from the Sun and that emitted from the surface of the Earth towards the outer space. Greenhouse gases in the atmosphere, including water vapor, carbon dioxide, methane and nitrous oxides, act to make the surface much warmer, because they absorb and emit heat energy in all directions (including downwards), keeping Earth’s surface and lower atmosphere warm. The primary cause of climate change is the burning of fossil fuels, such as oil and coal, which emits greenhouse gases into the atmosphere – primarily carbon dioxide. We give a review about the activity of the Intergovernmental Panel on Climate Change and the United Nations Climate Change Conferences. Shortly investigate the different global climate models and some regional climate models. Finally discuss the results of regional climate model simulations for the Carpathian Basin.

In the aftermath of the Paris Agreement, there is a crucial need for scientists in both thermal physiology and climate change research to develop the integrated approaches necessary to evaluate the health, economic, technological, social, and cultural impacts of 1.5°C warming. Our aim was to explore the fidelity of remote temperature measurements for quantitatively identifying the continuous redistribution of heat within both the Earth and the human body. Not accounting for the regional distribution of warming and heat storage patterns can undermine the results of thermal physiology and climate change research. These concepts are discussed herein using two parallel examples: the so-called slowdown of the Earth’s surface temperature warming in the period 1998-2013; and the controversial results in thermal physiology, arising from relying heavily on core temperature measurements. In total, the concept of heat is of major importance for the integrity of systems, such as the Earth and human body. At present, our understanding about the interplay of key factors modulating the heat distribution on the surface of the Earth and in the human body remains incomplete. Identifying and accounting for the interconnections among these factors will be instrumental in improving the accuracy of both climate models and health guidelines.

The mismatch between fossil isotopic data and climate models known as the cool-tropic paradox implies that either the data are flawed or we understand very little about the climate models of greenhouse warming. Here we question the validity of the climate models on the scientific background of orbital noise in the Earth system. Our study shows that the insolation pulsation induced by orbital noise is the common cause of climate change and atmosqheric concentrations of carbon dioxide and methane. In addition, we find that the intensity of the insolation pulses is dependent on the latitude of the Earth. Thus, orbital noise is the key to understanding the troubling paradox in climate models.

Though responses to the Anthropocene have largely come from the natural and social sciences, religious responses to the Anthropocene have also been gaining momentum and many scholars have been calling for a religious response to complement scientific responses to climate change. Yet because Genesis 1:28 does indeed tell human beings to ‘subdue the earth’ monotheistic religions have often been understood as complicit in the human exceptionalism that is thought to have created the conditions for the Anthropocene. In distinction to such Biblical traditions, indigenous animistic cultures have typically respected all forms of life as ‘persons’ and such traditions have thus become a source of inspiration for ecological movements. After discussing contemporary Christian efforts to integrate the natural sciences and the environment into their responses to the Anthropocene, this article will turn to animism and seek to evaluate the risks and benefits that could ensue from a postmodern form of animism that could provide a necessary postsecular response to the Anthropocene.
