Choose a theory from your undergraduate education in any discipline. It should be a commonly used theory for the general public such as Maslow, Darwin, Descartes, or others you used in physiology courses, chemistry, business courses, etc. Do not use a nursing theory. Provide the theory in your response. Identify the two concepts and the proposition between them. Explain the concepts. How might the terms used differ from the general use of the term? How might the term be confused or misinterpreted? Format your theory in the form “psychosocial development (Concept A) progresses through (Proposition) stages (Concept B)”.
her drastic effect of global warming is the shrinking of the ice sheets. Their decrease in mass lies by about 119 billion tons in Antarctica in just 23 years from 1993 to 2016 – its rate tripled in the last decade. Translated into area, this means that during the last 40 years, about two and a half million square kilometres of ice melted, broke away or in any other way diminished, as Figure 2 demonstrates. Figure 2: How the Arctic ice sheets are declining in area (NASA 2018a) The Arctic sea ice, which is not only a crucial habitat for polar bears but also plays its role in regulating the European temperature, is rapidly declining in extent and thickness (Frey 2017). During winter 2017/2018, it has reached its second lowest maximum of ice extent in the Arctic (BBC 2018). It is possible to survey its decline by the use of satellite observations (NASA 2018a). 3.4 Retreating glaciers The ice also retreats in the Alps, Himalaya, Africa – everywhere around the world glaciers are retracting. Satellite observations also indicate that the already reduced amount of snow in the northern hemisphere is melting earlier each year. This melting ice and the overall increased extent of thawing permafrost results in the removal of a critical water source. The change could force the relocation of one-sixth of Earth ́s population which critically depends the runoff of glaciers as drinking water source or on end-of-season snowpack (National Research Council 2010). It could also affect the water availability and quality through the release of pollutants and organics captured in the ice – these gases also contribute to climate change (Swann et al. 2009, Pfirman et al. 1995). Monitoring these changes is possible through measuring the vertical temperature profile of permafrost and the ice volume fraction. The changes are also revealed by observing the surface snow cover and temperature, vegetation and surface elevation change (National Research Council 2010).>GET ANSWER
