Causes and Consequences of Climate Change . This is a list of the 620 authors contributing to Climate Change 2007: The Physical Science Basis, which was the 996 page contribution of Working Group I to the IPCC Fourth Assessment Report.Their report describes the causes and climate consequences of global warming.. Joseph Fourier in 1824, Claude Poulliet in 1827 and 1838, Eunace Foote (1819–1888) in 1856, Irish physicist John Tyndall (1820–1893) in 1863 onwards, Svante Arrhenius in 1896, and Guy Stewart Callendar (1898–1964) are credited with discovering the importance of CO 2 in climate change. Causes of Climate and Environmental Changes: The need for Environmental-Friendly Education Policy in Nigeria DR. MRS. NWANKWOALA, H. N. L. (Ph.D) DEPARTMENT OF EDUCATION FOUNDATION MANAGEMENT, IGNATIUS AJURU UNIVERSITY OF EDUCATION, PORT HARCOURT, RIVERS STATE NIGERIA Abstract. Global warming is the planet's response to higher levels of greenhouse gases in the atmosphere. include burning fossil fuels, cutting down forests, and developing land for farms, cities, and roads. It is ideal for any secondary/K9-K12 Geography course, especially GCSE. Climate science tells us that further warming and risk increase can only be stopped by achieving zero net greenhouse gas emissions. 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. Climate change and sustainability. This booklet is intended to help people understand what is known about climate change. To find the source of this threat it is necessary to focus on global warming caused by climate change, which causes sea level rise in three different ways: The first is the thermal expansion: water, when heated by temperature rise, tends to expand, ie, oceans take up more space. This becomes obvious when scientists probe beyond changes in the average temperature of the planet and look more closely at geographical and temporal patterns of climate change. These gases include; • Carbon IV oxide. Climate change causes a variety of physical impacts on the climate system.The physical impacts of climate change foremost include globally rising temperatures of the lower atmosphere, the land, and oceans. The luminosity, or brightness, of the Sun has been increasing steadily since its formation. Foote's work was not appreciated, and not widely known. During the course of global warming, the energy balance and thus the temperature of the earth change, due to the increased concentration of greenhouse gases, which has a significant impact on humans and the environment. Climate change is the catch-all term for the shift in worldwide weather phenomena associated with an increase in global average temperatures. Natural causes of climate change. This book explains the three main physical possible causes of global climate change. From time to time, changes in climate … Enormous progress has been made in increasing our understanding of climate change and its causes, and a clearer picture of current and future impacts is emerging. Abrupt climate changes occur when a threshold or ‘tipping point’ in the climate system is crossed, causing large changes or impacts to the climate. Climate change, together with other natural and human-made health stressors, influences human health and disease in numerous ways. Causes of Climate Change. Climate change caused by the global increase in temperatures triggers multiple negative effects on the planet. But as climate change causes changes to the start and end of seasons, migrating animals can find that they arrive at breeding grounds at the wrong time - before food is available, for example. Climate change has always happened on Earth, which is clearly seen in the geological record; it is the rapid rate and the magnitude of climate change occurring now that is of great concern worldwide. Climate change affects the social and environmental determinants of health – clean air, safe drinking water, sufficient food and secure shelter. Ice ages are the prototypical example of a long time scale change. Important considerations include age, economic resources, and location. All of these are adding up and causing numbers of puffins to fall sharply. What Causes Climate Change? Climate change is a term that refers to major changes in temperature, rainfall, snow, or wind patterns lasting for decades or longer. Polar ice shields are melting and the sea is rising. IPCC 2007, Summary for Policymakers, in Climate Change 2007: Impacts, Adaptation and Vulnerability. The remaining 14% comes from renewable energy sources such as hydro, solar and wind, which do not emit carbon. Climate science encompasses a range of disciplines, from oceanography and meteorology, to chemistry, physics, biology and computer science. Volcanic eruptions can release large quantities of dust and other gases (such as sulphur dioxide) into the atmosphere. Climate change has positive and negative impacts and physical and human causes. This... Volcanic activity. Scientific data show that abrupt changes in climate at the regional scale have occurred throughout history and are characteristic of Earth’s climate system. Climate change affects all regions around the world. Contribution of Working Group II to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change, Cambridge University Press, Cambridge, UK, p. 17. While the weather is quite variable, the trend over a longer period, the climate, is more stable. Both human-made and natural factors contribute to climate change: • Human causes. Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that Earth’s climate responds to changes in greenhouse gas levels. Climate change destabilises the Earth’s temperature equilibrium and has far-reaching effects on human beings and the environment. The earth's own feedback loop, which increases the amount of water vapor in the atmosphere and warms the oceans, accelerates the warming and contributes to climate change, a related phenomenon. They create a blanket that traps the heat from the sun and sends it back to the planet’s surface. Between 2030 and 2050, climate change is expected to cause approximately 250 000 additional deaths per year, from malnutrition, malaria, diarrhoea and heat stress. Sea level rise: main causes. Loosely defined, climate is the average weather at a distinct place that incorporates temperature, precipitation, and … Greenhouse gases in the atmosphere absorb heat radiation. Non-stationary: As the Earth continues to warm, physical climate risk is ever-changing or non-stationary. Some existing health threats will intensify and new health threats will emerge. Natural causes, human causes, climate forcers, greenhouse gas, fossil fuels. Individual... Tectonic activity. In some regions extreme weather events and rainfall are becoming more common while others are experiencing more extreme heat waves and droughts. Climate change, the periodic modification of Earth’s climate caused by atmospheric changes and the atmosphere’s interactions with geologic, chemical, biological, and geographic factors. Solutions: … There is no question that increased levels of greenhouse gases must cause Earth to warm in response. ... Electricity generation is the main cause of carbon pollution in Australia as 73% of our electricity comes from burning coal and 13% from burning gas. There are many “natural” and “anthropogenic” (human-induced) factors that contribute to climate change. to climate change. Climate change is lasting change in long term weather patterns over a significant period of time. Climate change is lasting change in long term weather patterns over a significant period of time. Human causes of climate change include industrial activity, agricultural practices and deforestation. These effects interrelate with each other and increase their violence, putting at risk the species that inhabit the Earth, including the humans.. IPCC, 2013: Summary for Policymakers. Different influences on climate lead to different patterns seen in climate records. Causes of climate change Solar variability. This list is limited to people acknowledged as authors or editors on the report. However, the climate still changes over time scales of decades to millennia. Global warming is an aspect of climate change, referring to the long-term rise of the planet's temperatures. Causes of climate change; Climate change consequences; Climate change consequences. Other human activities, such as agriculture and deforestation, also contribute to the proliferation of greenhouse gases that cause climate change. Volcanic activity can influence climate in a number of ways at different timescales. Greenhouse gas emission is a major human causes of climate change, and their sources include transportation, electricity production, burning fossil fuel in industries, commercial and residential application, agriculture, and land use.
