CLIMATE CHANGE - 3º ESO A

IPCC I ntergovernmental Panel On Clim ate Change The aim of this report is to know about what is IPCC, its overview, its history, its structure, preparing reports,future work and its scholarship. We have searched this information in IPCC´s web and in wikipedia. 1.WHAT IS IPCC? The Intergovernmental Group of Experts on Climate change or the intergovernmental Panel on climate change, known by the acronym in English IPCC. 2.OVERVIEW An open and transparent review by experts and governments around the world is an essential part of the IPCC process, to ensure an objective and complete assessment and to reflect a diverse range of views and expertise. Through its assessments, the IPCC identifies the strength of scientific agreement in different areas and indicates where further research is needed. The IPCC does not conduct its own research. 3.History of the IPCC The Intergovernmental Panel on Climate Change (IPCC) was established in 1988

GLOBAL WARMING AND NATURAL DISASTERS  The aim of this report is to explain the relathionship of both topics and, how the climate change can affect the Earth and causes natural disasters. What is the global warming? Global warming is the increase of the overall temperature in the atmosphere, shown by temperature measurements and by multiple effects of the warming. It is generally attributed to the greenhouse effect gases. What are global warming effects? Global warming is projected to have a number of effects on the oceans. That effects include tha glaciers are melting, sea levels are rising, cloud forests are dying, and wildlife is scrambling to keep pace. It has become clear that humans have caused most of the past century's warming by releasing heat-trapping gases as we power our modern lives. Called greenhouse gases, their levels are higher now than at any time in the last 800,000 years. Greenhouse effect We often call the result global war

CAUSES OF CLIMATE CHANGE / GREENHOUSE EFFECT GREENHOUSE EFFECT Introduction   T he aim of this report is to explain what is the greenhouse effect, what are its positives and negatives effects, and how we can contribute to decrease the hight emission of gases to the atmosphere. What is the Greenhouse effect? The greenhouse effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. Greenhouse gases include water vapour, carbon dioxide, methane, nitrous oxide, ozone and some artificial chemicals such as chlorofluorocarbons (CFCs). The absorbed energy warms the atmosphere and the surface of the Earth. This process maintains the Earth’s temperature at around 33 degrees Celsius warmer than it would otherwise be, allowing life on Earth to exist. Greenhouse effect and human activities The problem w

E NVIROMENTAL POLLUTION/ CONTAMINATION The aim of this report is to look at the causes and consequences of environmental pollution and contamination. Our sources include facts and figures from several recent websites. We have searched information related with the negative effects, the types of contamination and the possible solutions to avoid these problems. We have used information, photos and several videos we have found in the Internet. The objective of this project is to promote all the information we found out about this topic and teach people how we can prevent this kind of problems. 1. WHAT IS ENVIROMENTAL POLLUTION? Environmental pollution   is one of the most serious problems facing humanity and other life forms on our planet today.  Environmental pollution  is defined as “the contamination of  the physical and biological components of the   earth/atmosphere   system to such an extent that normal environmental processes are adversely affected.”
