MORE ON CLIMATE CHANGE

Global warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions. This results in an increased emission of greenhouse gases. Short-wave solar radiation sinks into the Earth's atmosphere and warms its surface; while longwave infrared radiation emitted by earth's surface is absorbed, and then re-emitted by trace gases. Climate changes occur in our earth's atmosphere due to a buildup of greenhouse gases. Greenhouse gases can occur naturally as well as a result of human activities. Problems can occur when higher concentrations of greenhouse gases are present in our atmosphere because they have enhanced our earth's heat trapping capability. There are many misconceptions about global warming. Some believe that pollution causes global warming, but the fact is global warming is the result of burning fossil fuels, coal, and oil that release carbon dioxide.

By the end of this century, our planet may look very different from how it does today. Many small island nations might no longer exist, inundation of coastal areas could lead to the displacement of hundreds of millions of people, and former agricultural lands could become unable to support crops. While all countries are vulnerable to the consequences, developing countries are especially at risk. Their economies will suffer most from the heightened frequency of extreme droughts, floods and storms associated with climate change. There is a real risk that climate change could undermine human development. We must not let that happen”.By the end of this century, our planet may look very different from how it does today.

CLIMATE CHANGE

Climate change is the biggest challenge that we face in the world today. It is already leading to significant changes in the world’s physical environment. Extreme weather events are becoming more frequent. Glaciers are melting. Sea ice and snow cover are declining. Animals and plants are responding to an earlier spring. Global warming has already driven up mean sea levels by 10-20 centimetres (4-8 inches) during the last 100 years, and this is forecast to rise by up to another 88 centimetres (35 inches) by 2100. It is a sobering fact that around 100 million people globally live less than 88 centimetres above sea level.” Climate change is the biggest challenge that we face in the world today.

Wind Energy

Wind power according to many individuals and scientists is produced by windmills and wind turbines. Wind turbines are all over the world today and in full use. These wind turbines supply much of the energy that many individuals have going into his or her homes now; however, they are just simply not aware of it. Wind power through the use of the wind turbines supply many power plants with an alternative energy source. One that is environmentally safe and effective.

It is hard to find a topic to write about

Tonight I want to write about something good, I want to finish my day thinking about funny things or at least positive ones.
I have been seated in from of my laptop for about 5 minutes trying to find a good topic, but........nothing came up.
