INTRODUCTION AND HISTORY:
What is Global Warming?
Global warming is the rise in the average temperature of Earth's atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century, Earth's mean surface temperature has increased by about 0.8 °C (1.4 °F), with about two-thirds of the increase occurring since 1980.
Facts to be remembered:
Our planet is warming up, and not in a good way! The last 20 years were the hottest in 400 years, according to several studies. An upsurge in the amount of extreme weather events, such as wildfires, heat waves, and strong tropical storms, is also attributed in part to climate change by some experts.
Between 1970 and 2004, global greenhouse gases (GHGs) have increased 70 per cent due to human activities. You don’t have to be an environmentalist to know that’s a massive jump in pollutants and a big problem for the effect it has on the planet’s natural temperature. It’s even worse for carbon dioxide; its annual emissions grew by about 80 per cent between the same periods. Our society is pouring carbon dioxide into the atmosphere much faster than plants and oceans can absorb it.
What is Climate Change?
Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions, or in the distribution of weather around

    Global warming is not a 20th century phenomenon. It has, in fact, occurred in the past more than once, along with periods of extreme cold known as the ice ages. With so much written and reported about global warming, sometimes it's difficult to detect which is fact and which is just part of scientific scare tactics. Here are some facts about global warming that might help:…

    Earth's climate constantly changes, and many scientists believe that the temperature rises we see in this decade are a natural phenomenon that occurs every so many years. Around 25,000 years ago, it is believed that earth was covered by large areas of ice. And then, about 7,000 years ago, temperatures began to rise and the "Ice Age" came to an end.…

    The first reason is because global warming comes and goes. The earth naturally heats up and cools down. Thirty years ago we thought the biggest threat was global cooling and now the biggest threat is global warming. Through out history there has been numerous cooling and warming periods and we are now going though on of those natural warming periods. We also experienced a warming period during the Medieval Warm Period around 1100 AD when Vikings settled into Greenland because it used to be green and the perfect place to grow crops (1); grapes suitable for winemaking were also reported growing in England (2); and the tree line in Scandinavia was 100–200 m higher than present (3).…

    Climate is the weather pattern in an area over long period of time. Climate is more focused on the long term rather than day to day or week to week changes. Due to uneven heating of the Earth’s surface, climate changes depending on where the location is on the planet. Factors such as incoming solar energy, Earth’s rotation, and air and water movements all affect an area’s climate. Different levels of these factors influence the biomes on the planet.…

    According to Live Science, global warming is used to describe a gradual increase in the average temperature of the Earth 's atmosphere and its oceans, a change that is believed to be permanently changing the Earth 's climate forever. The scientific consensus on climatic changes to global warming is that the average temperature of the Earth has risen between 0.4 Cto 0.8 C over the past 100 years (as cited in Live Science, n.d.).…

    Climate change refers to change in average weather patterns and can be caused by both natural processes and human activities. In the past, the earth's climate has been affected by natural factors such as changes in solar output and the discharge of volcanic ash. In fact, the planet has been through many periods of cooling and warming. The last period of major cooling ended about 10,000 years ago.…

    The changes in the temperature and weather patterns have already begun to cause changes in land that was once able to produce or grow food. More and more areas are experiencing drought, which has caused a lack of food in areas, which are in great need of water. Global warming has also had the opposite effect in some areas creating catastrophic flooding and other weather phenomenon that has impacted the environment in a disastrous way.…

    Global warming can be defined as; “An increase in the earth’s atmospheric and oceanic temperatures widely predicted to occur due to an increase in the greenhouse effect resulting especially from pollution” (Merriam-Webster Online Dictionary, 2008). According to University of Phoenix Global Warming (2008), the data accumulated from daily measurements indicate that the Earth’s average surface temperature in 2005 was the third highest since the mid-1800s. Apparently the last two decades of the 20th century were its warmest.…

    The aspects of climate change we are certain of are as follows, increased water availability in moist tropics and high latitudes, and decreasing water availability and increasing drought in mid-latitudes and semi-arid low latitudes, hundreds of millions of people exposed to increased water stress causing localized negative impacts on small business and coastal areas, and increased damage from floods and storms, and leading to erosion in coastal areas in addition based on satellite observations since the early 1980s there is high confidence that there has been a trend in many regions towards earlier “greening” ( measured by the normalized difference vegetation index) Of vegetation in the spring linked to longer thermal growing seasons due to recent warming. About which we are uncertain is many of the long term effects of climate change.…

    Global average temperature rose significantly during the past century. The prevailing scientific view is that most of the temperature increases since mid-20th century has been caused by increases in atmospheric greenhouse gas concentrations produced by human activity. Most scientists agree that planet’s temperature has risen 0.5 degree Celsius since 1900 and will continue to increase at an increasing rate. As a result, the world is getting warmer. The year 1990 was the hottest year in the last century.…

    What is global warming? Global warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. This hurts many people, animals, and plants. Many cannot take the change, so they die. However, global warming has its causes and it also has its effects on humans, and animals.…

    Scientists from the University of Hawaii at Manoa calculated that by 2047, plus or minus five years, the average temperatures in each year will be hotter across most parts of the planet than they had been at those locations in any year between 1860 and 2005. (Gillis) Climate change is a very serious issue in our world at the moment. Climate change is already affecting glacier melting, sea level rise, the range and distribution of plants and animals, tree blooming times, the length of growing seasons, freezing and thawing of rivers and lakes, and the extent of the permafrost.
