Estudo da influência das mudanças climáticas na erosão marinha dos municípios litorâneos de Paulista e Olinda em Pernambuco

Abstract

Climate change has been the scene of research and consequent discussions, thus taking its growing space in society, knowing that the changes that have occurred are caused by the increase in greenhouse gas emissions on the planet. Unexpectedly these changes cause rains that destroy buildings, earthquakes, destroy cities, beaches are taken by ever-increasing waves. According to the IPCC in 2007, the global average temperature has been increasing, resulting in the thawing of the glaciers and also the coastal erosion in some of the planet's beaches. Coastal erosion, one of the causes of climate change, is a problem found in approximately one third of the beaches in Pernambuco. On the beaches of the municipalities of Paulista and Olinda both in the Metropolitan Region of Recife (RMR) in Pernambuco, this problem has been occurring for years, in this way the present work analyzes the influence that climate change has been causing on marine erosion in the municipalities under study. For this, geoprocessing and remote sensing were used, which are technologies that provide images and analysis of the information of phenomena that occur on the Earth's surface. It was also possible to better understand the dynamics of tides and to confirm the sediment gain of the beach of Olinda and Pau Amarelo and the decrease of these sediments at Janga beach, analyzing and confirming the effect that climate change has brought to the environment.
