Global warming refers to the rising average temperature of Earth’s atmosphere and oceans‚ which started to increase in the late 19th century and is projected to keep going up. Since the early 20th century‚ Earth’s average surface temperature has increased by about 0.8 °C (1.4 °F)‚ with about two thirds of the increase occurring since 1980.[2] Warming of the climate system is unequivocal‚ and scientists are more than 90% certain that most of it is caused by increasing concentrations of greenhouse

What is the main cause of global warming? In the last century‚ the sea level has rose for about 17 centimetres. The rate in the last decade is however‚ nearly the double of last century. Major global surface reconstructions also showed that the Earth has warmed since 1880 and it’s still going on. Oceans are also warming up‚ due to the heat. Not only that‚ the Greenland and Antarctic ice sheets are melting‚ glaciers are disappearing and extreme weather events have occurred more often. All these

Global dimming‚ a gradual reduction in the amount of global direct irradiance at the Earth’s surface‚ has partially counteracted global warming from 1960 to the present.[55] The main cause of this dimming is aerosols produced by volcanoes and pollutants. These aerosols exert a cooling effect by increasing the reflection of incoming sunlight. The effects of the products of fossil fuel combustion—CO2 and aerosols—have largely offset one another in recent decades‚ so that net warming has been due to

I Introduction My awareness of the phenomenon called either "global warming" or "climate change" started immediately before the Kyoto Summit in December 1997. I read articles in the media which said that many scientists believe that the threat of global arming was alarming and that our political leaders would have to do something in order to prevent the climate from getting hotter and hotter. Since this conference climate change has fascinated me. This research paper is divided into two main parts:

GLOBAL WARMING Name Instructor Course Date Global Warming Climate change caused by global warming is the hugest environmental crisis the world is facing. Global warming is termed as a gradual increase in the average temperature of the earth’s atmosphere and oceans‚ a change which has been proven to change the earth’s climate completely. Looking at the data presented by scientists‚ it is evident that the earth is warming. It is the current discussed factor addressed across

Global Warming Global warming is the most pressing challenge facing the world today. After examining what global warming is‚ I have realized that human activities have a large impact on how the earth’s surface temperature is due to the greenhouse effect. I also have realized the impact that global warming can have on the earth. We as human’s need to do what we can to lower our contributions to the global warming before it is too late. Global warming is the increase of earth’s average

Global Warming by James Inmon Global Warming is the effect on climate change brought about by human impact on the environment. Just one degree increase in the average global temperature could have a big impact on our world. Three of the more common sources of Global Warming are; the burning of fossil fuels‚ industrial pollution‚ and urban sprawl. Fossil Fuels are carbon based compounds like coal and gasoline. When these fuel sources are burned‚ they release carbon dioxide and other air pollution
