EFFECTS OF CLIMATE CHANGE ON WOMEN

Introduction

Definition of basic terms
What is Weather?
The term weather describes the state of the air at a particular place and time – whether it is warm or cold, wet or dry, and how cloudy or windy it is, for example. It affects many of the things that we do, from the clothes we wear and the food we eat, to where we live and how we travel. As a result, the weather is of great interest to people everywhere, from meteorologists, the scientists who study it in great depth, to you and I in our everyday lives. In fact, one of the main topics of conversation is often what the weather will do next the .Weather is very changeable and unpredictable. What is Climate?

The normal pattern of weather experienced in a particular area over a long period of time is known as the climate.   The climate tells us how hot, cold or wet it is likely to be in different parts of the world at different times of year. For example, tropical countries have hot climates and the Antarctic has a cold climate. The climate may include four seasons a year - spring, summer, autumn and winter - or a wet and a dry season. Our climate depends on our position on the earth and our distance from the sun. We will learn more about this in the Days and Seasons section.  What is weather forecasting?

Weather experts use computer technology and data from stations and satellites all over the world to predict the weather.   By carefully monitoring weather conditions it is possible to predict when change is due - what we know as weather forecasting. What is Climate Change?

Climate change refers to any significant change in the measures of climate lasting for an extended period of time. In other words, climate change includes major changes in temperature, precipitation, or wind patterns, among other effects, that occur over several decades or longer. What is Global Warming?

Global warming refers to the recent and ongoing rise in global average temperature near Earth's surface. It is caused mostly by increasing concentrations of greenhouse gases in the atmosphere. Global warming is causing climate patterns to change. However, global warming itself represents only one aspect of climate change.

Climate change is happening

Our Earth is warming. Earth's average temperature has risen by 1.4°C over the past century, and is projected to rise another 2 to 11.5°C over the next hundred years. Small changes in the average temperature of the planet can translate to large and potentially dangerous shifts in climate and weather. Rising global temperatures have been accompanied by changes in weather and climate. Many places have seen changes in rainfall, resulting in more floods, droughts, or intense rain, as well as more frequent and severe heat waves. The planet's oceans and glaciers have also experienced some big changes - oceans are warming and becoming more acidic, ice caps are melting, and sea levels are rising. As these and other changes become more pronounced in the coming decades, they will likely present challenges to our society and our environment.

Who is Responsible?
Over the past century, human activities have released large amounts of carbon dioxide and other greenhouse gases into the atmosphere. The majority of greenhouse gases come from burning fossil fuels to produce energy (Charcoal), although deforestation, industrial processes, and some agricultural practices also emit gases into the atmosphere. Greenhouse gases act like a blanket around Earth, trapping energy in the atmosphere and causing it to warm. This phenomenon is called the greenhouse effect and is natural and necessary to support life on Earth. However, the build-up of greenhouse gases can change Earth's climate and result in dangerous effects to human health and welfare and to ecosystems. There other elements of people’s homes that contribute to climate change indirectly. Everything, from furniture to computers, from clothes to carpets, all use energy...
