This year’s ozone hole over the South Pole is one of the worst‚ despite scientists only a year ago saying it had shrunk to its smallest size. By September 12 the hole above Antarctica was 26 million square kilometres‚ Nasa and the National Oceanic and Atmospheric Administration said. The hole – which grows each spring and then shrinks again each year – was among the 10 worst since records began 26 years ago. Colder-than-average temperatures in the stratosphere had caused the larger-than-average

This article was of particular interest to me as this is the second time in this week that I have read about the effects of climate change on crops. Also‚ this article reminds me of what I have experienced in my hometown. I come from a small town in India where the agriculture is a predominant industry. Growing up‚ I have seen the changes in farming as well as in the farmers. Any change in the agriculture has a major effect on the country’s economy. The following are the changes that I have

SAFETY PRECAUTIONS IN USING ELECTRICITY:- 1. Avoid water at all times when working with electricity. Never touch or try repairing any electrical equipment or circuits with wet hands. It increases the conductivity of electric current. 2. Never use equipment with frayed cords‚ damaged insulation or broken plugs. 3. If you are working on any receptacle at your home then always turn off the mains. It is also a good idea to put up a sign on the service panel so that nobody turns the main switch ON

might CO2 emissions have on overall global warming? In the 19th century‚ scientists realized that gases in the atmosphere cause a "greenhouse effect" which affects the planet’s temperature. These scientists were interested chiefly in the possibility that a lower level of carbon dioxide gas might explain the ice ages of the distant past. At the turn of the century‚ Svante Arrhenius calculated that emissions from human industry might someday bring a global warming. Other scientists dismissed his idea

Global Warming Essay: Facts about Global Warming Spread Environmental Awareness and Encourage Fight against Global Warming Through Your Global Warming Essay The definition of Global warming is‚ “The observed and projected increase in the average temperature of Earth’s atmosphere and oceans”. Human actions‚ primarily the release of green house gases from smokestacks‚ vehicles‚ and burning forests‚ are perhaps the chief power causing this situation. CO2 (Carbon dioxide) emissions belong to the most

of ecosystems to threats to human health. Experts in fields from forestry to economics‚ even national security experts‚ pitched in to assess the range of possible consequences. It was impossible to make solid predictions given the complexity of the global system‚ the differences from one region to another‚ and the ways human society itself might try to adapt to the changes. But by the start of the 21st century‚ it was clear that climate change would bring serious harm to many regions — some more than

Global Warming Planet earth has an abundance of natural resources‚ which makes it unique and perfect for life to exist. However our use of these natural resources is creating a bit of a problem for us. Global warming is affecting our world in a negative way and mankind is exacerbating this problem. Today I am here to tell you what global warming is‚ why it is a problem and how we can solve it. Global warming is the increase in average temperature of earth’s land‚ sea and atmosphere. This is

Is Global Warming real? The term global warming does not have a universal definition. It is a term used by many governments‚ organisations and companies to describe the rise in the average temperature on Earth’s surface. Deborah White says ‘Global warming refers to the increased temperature of Earth’s surface‚ including land‚ water and near-surface air’. The atmosphere is made up of various gases‚ some of these gases are called greenhouse gases. These natural gasses do not cause concern‚ however

Global warming is an urgent issue nowadays that needs solution to be able to continue our living on the Earth. Research paper on global warming should be well-structured and well-written. It should cover the most important aspects of the problem and present a strong argument against global warming and human activities which lead to this problem. Global warming research paper outline usually includes main aspects discussed in the paper. It should contain the notion of global warming. For example

What is Global Warming? Global Warming is defined as the increase of the average temperature on Earth. As the Earth is getting hotter‚ disasters like hurricanes‚ droughts and floods are getting more frequent The average facade temperature of the globe has augmented more than 1 degree Fahrenheit since 1900 and the speed of warming has been almost three folds the century long average since 1970. This increase in earth’s average temperature is called Global warming. More or less all specialists
