Climate change:

Climate change is a big environmental problem, and one of the most significant trials of time, climate change has been widely argued all over the world. There are many reasons of climate changes, but the main cause is to introduces new methodology to guess and they utilizes this methodology to assess the impressions of some climate change the effects of climate dangerous on health of human being. Rise in atmospheric carbon dioxide started with the industrial revolution, when coal was used in immense quantities as fuel. Today millions of vehicles are coming on roads every year; they are emitting thousands of tons of carbon dioxide into the air every day. Glaciers are melting fast, and all these are evidence of rapid climate change.

 Global warming:

Global warming is one of the most challenging issues faced by the world, the amount of carbon dioxide in the atmosphere  has attained level as much 27% higher than at  any time during last 6.5 million years, and this the gas which is mainly responsible for global warming. In last many years, the average global temperature has risen by 0.20c per year, which is hundred times greater than rise in temperature in comparable periods in the past. Vehicles emitting thousands of tons of carbon dioxide in air on daily basis, glaciers in green land and the Himalayas are melting fast, splits have appeared in iceberg, and the increase of population is also a reason of global warming. Countries causing the most pollution are refusing to reduce the emission of their greenhouse gases. One of the major dangers of the world global warming is the inundation of some of the largest parts and cities of the world. Due to melting the glacier and iceberg, and rise of water from the oceans can inundation the many parts of world.

 Green house affects:

 

The Greenhouse effect is a regular method that warms the Earth’s surface. When the sun’s energy reaches the Earth’s atmosphere, some of it is returned back to space and some is riveted and re-radiated by greenhouse gases. The absorbed energy warms the earth and the surface of the earth. The greenhouse process that happens when gasses on Earth’s atmosphere trap the sun’s heat and this progression makes Earth much warmer than it would be without an atmosphere. The greenhouse effect is one of the things that make earth an easy place for living. The greenhouse effect mean nearly of the electromagnetic radiation from the sun passes through the atmosphere, but maximum is absorbed and re-emitted in all directions by greenhouse gas molecules and clouds. The effect of this is to warm the earth’s surface and the lower atmosphere. The main gasses those are responsible for the greenhouse effect include carbon dioxide, methane, nitrous oxide and water vapor. Greenhouse gasses have different chemical stuffs and are removed from the atmosphere over time by different procedures.  Ozone is exactly a greenhouse gas, but ozone is helpful or harmful dependent on where it is found in the earth’s   atmosphere. The protective advantage of stratospheric ozone outweighs its contribution to the greenhouse effect and global warming.

At every step of her life, she is confronted with the evil eyes and abusive words of men and sometimes even physical abuse. An educated and intelligent girl, who is in no way inferior to a man, who is a topper in college and university, is not getting a good job even for a meager salary of ten to twelve thousand because of men who work there.
