Global warming is the increase in average temperature of the Earth’s atmosphere and oceans over time. Most of the warming observed over the last 50 years is attributable to human activities‚ especially the emission of greenhouse gases such as carbon dioxide gas. In recent years‚ extreme heat waves caused more than 20000 deaths in Europe. Also‚ melting icebergs and rising sea levels are observed. Global warming is a crucial problem in the world‚ it may lead to disastrous consequences such as extinction

Global Warming Have you noticed that our summers have been extremely hot and our winters have been less extreme than in previous years? If so you are noticing what is referred to as global warming. What this refers to is an overall increase in the temperatures around the world. Due to human activities‚ such as pollution and the amount of gas we use‚ and through natural events‚ it had caused the average temperature across the world to rise substantially. In addition‚ the rise of use in gases

Global Warming: A Problem That Needs Immediate Attention &&&&&& PHI 103 &&&&&&& June 16‚ 2012 Global Warming: A Problem That Needs Immediate Attention With the rise in the Machine Age during the late 1800’s‚ early scientists believed that the byproducts released by these new machines would have adverse effects on the environment. The scientists began to study these effects and noticed that the earth’s global temperature was rising 1.4 degrees

Global Warming Global warming is an important issue in our society that a lot of people should be interested in as it will affect our lives for the rest of our life. How many of you already feel very warm in this room/hall? What if I tell you that in another 40 years‚ the temperature outside will be so hot it will feel like a baking bun inside an oven. This will be the exact situation that we’ll be in if we don’t stop it. Global warming literally means that the Earth’s average temperature is
Premium Global warming Carbon dioxide
Global Warming Causes Global warming is primarily a problem of too much carbon dioxide (CO2) in the atmosphere—which acts as a blanket‚ trapping heat and warming the planet. As we burn fossil fuels like coal‚ oil and natural gas for energy or cut down and burn forests to create pastures and plantations‚ carbon accumulates and overloads our atmosphere. Certain waste management and agricultural practices aggravate the problem by releasing other potent global warming gases‚ such as methane and nitrous

challenges earth is facing is Global Warming. The global warming hypothesis orginated in 1896 when Svante Arrhenius‚ a Swedish chemist‚ developed the theory that carbon dioxide emissions from the burning of fossil fuels would cause global temperatures to rise by trapping excess heat in the earth’s atmosphere. The term “Global Warming” signifies the temperature of the earth’s neon- surface air. The change in climatic conditions is one of the impacts of global warming. It is directly impacting on rising

Abstract This report studies secondary research to discover the effects of global warming and the consequences it has on sea levels‚ ice melting and the polar bear. Websites researched were NASA‚ ICUN‚ National Geographic‚ BBC News‚ The Independent‚ IPCC‚ Arctic Council‚ National Resources Defense Council‚ UN News and D.V.D. called ‘An Inconvenient‚’ truth. Evidence researched supports the conclusion that scientists believe global temperatures have been rising and that human activity is a significant

Introduction A Global Warning: Global Warming | The world is warming dangerously. It depends either on the natural causes or the artificial causes like human based greenhouse gases. This affects both the vegetation and zoological environment and also the human | life. Its effects are gradually increasing every year.The purposes of our project are:·To investigate the causes and the effects of global warming and to present the results of our survey.·To attract attention on the solution proposals about

GLOBAL WARMING One of the most strongly debated topics on our earth is the issue of climate change. Global warming and climate change is refer to an increase in average global temperatures. Natural events and human activities are believed to be contributing to an increase in average global temperatures. This is caused primarily by increases in “greenhouse” gases such as Carbon Dioxide (CO2) I. Effect There are two effects of global warming which is the environmental and social changes

Global warming is the increase in the average temperature of the Earth’s near-surface air and oceans in recent decades and its projected continuation. Global average air temperature near the Earth’s surface rose 0.74 ± 0.18 °C (1.3 ± 0.32 °F) during the past century. The Intergovernmental Panel on Climate Change (IPCC) concludes‚ "most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas
