A simple reflection on climate change

Revista Eletrônica em Gestão, Educação e Tecnologia Ambiental

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.

Climate Change and Its Impacts

SpringerBriefs in Water Science and Technology, 2015

Front cover picture Cloud fractal image by Adrian Pope Human-made climate change poses threats to our world. Global temperatures are already some 0.6 °C higher than they were at the end of the last century, and observations so far this year indicate that 1997 will be one of the warmest years since records began. It is expected that global climate will continue to change throughout the next century, particularly if no additional action is taken to mitigate greenhouse gas emissions. International action to abate greenhouse gas emissions is focused on the work of the Framework Convention on Climate Change. This Convention draws on the regular assessments of the science by the UNEP/WMO Intergovernmental Panel on Climate Change (IPCC). The last full assessment was completed in 1995, and the next is planned for 2000/1. As part of the UK's contribution to our understanding of the science, the Department of the Environment, Transport and the Regions (DETR) funds the climate model at the UK Meteorological Office's Hadley Centre, one of the most advanced in the world. The DETR also funds dissemination of the model's output to those scientists able to assess the implied impacts of the predictions. This booklet describes work being submitted to the IPCC assessment process, in particular the recent results from the Hadley Centre model. However, climate predictions themselves need interpretation to determine the consequential impacts. This brochure therefore goes further and reports the results of a number of impacts studies that have drawn directly on the output of the Hadley Centre using state-of-the-art impact prediction models. While climate science is still an evolving area of research, it is hoped that this summary will give a sense of our ability to predict possible future climate and to assess its impacts.

1. Global Warming's Causes and Effects—In Under 7,000 Words

Science 1 History 3 Terminology 9 Classification of Environmental Problems 13 Sources Cited More Than Once 15 I here provide condensed synchronic and diachronic accounts of global warming. For more details, see my two other works mentioned at the end of this essay. I speak of "global warming and its effects" instead of "climate change" since global warming changes more than just the climate. For example, sea-level height is not a climate variable. I explain more in the section "terminology." In the final section, I provide a provisional typology that puts global warming in the context of environmental problems more generally. I almost killed myself doing research for this and the work on the Pacific Islands. So I hope some people will find it useful.

CLIMATE CHANGE - ITS CONSEQUENCE AND INTERNATIONAL RESPONSE

Climate change is a change atmospheric circulation or meteorological change in climate that persists over a long period of time (30 Year). Climate change refers to change in global surface temperature, change in pattern and intensity of rainfall and change in the extreme weather events. Climate change is the results of both natural as well as human causes like change in sun outputs, volcanic activities, and emission of green house gases by various human activities. It has become main global challenge and represents a unique security threat for us. Climate change is a change in climate cycle due to rise in mean global temperature caused by increasing amount of green house gases like carbon dioxide, sulfur dioxide, carbon mono oxide, colorofloro carbon and methane in the atmosphere. Increasing population and human activities like rapid industrialization urbanization and burning of fossil fuel change in land use pattern and development of the modern mode of transportation etc. are added further GHGs in environment. Secondly in other side depletion of forest by extension of agricultural activities leads to the decrease in the sink or consumption of 𝐶𝑂2. Therefore due

Climate Changes: Causes and Impact

2013

Present brings several environmental problems for people. Many of these are closely related, but by far the most important problem is the climate change. In the course of Earth evolution, climate has changed many times, sometimes dramatically. Warmer eras always replaced and were in turn replaced by glacial ones. However, the climate of the past almost ten thousand years has been very stable. During this period human civilization has also developed. In the past nearly 100 years since the beginning of industrialization the global average temperature has increased by approx. 0.6 ° C (after IPCC (Intergovernmental Panel on Climate Change)), faster than at any time in the last 1000 years.

Climate Change. Evidence and Causes

Climate Change. Evidence and Causes, 2023

Climate change is one of the defining issues of our times. It is now more certain than ever, based on many lines of evidence, that humans are changing Earth's climate. The atmosphere and oceans have warmed, which has been accompanied by sea level rise, a strong decline in Arctic sea ice, and other climate-related changes. The impacts of climate change on people and nature are increasingly apparent. Unprecedented flooding, heat waves, and wildfires have cost billions in damages. Habitats are undergoing rapid shifts in response to changing temperatures and precipitation patterns. The Royal Society and the US National Academy of Sciences, with their similar missions to promote the use of science to benefit society and to inform critical policy debates, produced the original Climate Change: Evidence and Causes in 2014. It was written and reviewed by a UK-US team of leading climate scientists. This new edition, prepared by the same author team, has been updated with the most recent climate data and scientific analyses, all of which reinforce our understanding of human-caused climate change. The evidence is clear. However, due to the nature of science, not every detail is ever totally settled or certain. Nor has every pertinent question yet been answered. Scientific evidence continues to be gathered around the world. Some things have become clearer and new insights have emerged. For example, the period of slower warming during the 2000s and early 2010s has ended with a dramatic jump to warmer temperatures between 2014 and 2015. Antarctic sea ice extent, which had been increasing, began to decline in 2014, reaching a record low in 2017 that has persisted. These and other recent observations have been woven into the discussions of the questions addressed in this booklet. Calls for action are getting louder. The 2020 Global Risks Perception Survey from the World Economic Forum ranked climate change and related environmental issues as the top five global risks likely to occur within the next ten years. Yet, the international community still has far to go in showing increased ambition on mitigation, adaptation, and other ways to tackle climate change. Scientific information is a vital component for society to make informed decisions about how to reduce the magnitude of climate change and how to adapt to its impacts. This booklet serves as a key reference document for decision makers, policy makers, educators, and others seeking authoritative answers about the current state of climate-change science. We are grateful that six years ago, under the leadership of Dr. Ralph J. Cicerone, former President of the National Academy of Sciences, and Sir Paul Nurse, former President of the Royal Society, these two organizations partnered to produce a highlevel overview of climate change science. As current Presidents of these organizations, we are pleased to offer an update to this key reference, supported by the generosity of the Cicerone family.
