Climate change Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions‚ or in the distribution of weather around the average conditions (i.e.‚ more or fewer extreme weather events). Climate change is caused by factors that include oceanic processes (such as oceanic circulation)‚ variations in solar radiation received by Earth‚ plate tectonics and

The world we live in does a pretty good job at self-destructing and repairing itself. A number of technological creations and the rise of the industrial era accelerated the consumption of materials and energy at a concerning rate.

hot topic all over the world today is whether or not biofuels should be implemented to help reduce greenhouse gas emissions. Biofuels are defined as “liquid fuels derived from biological materials; can be made from plants‚ vegetable oils‚ forest products‚ or waste materials” (Dale‚ Kline‚ Wiens‚ 2). Currently in Europe‚ the European Commission (EC) is committed to reducing the total green house gas emissions 20% by 2020‚ and 80-95% by 2050. The EC plans on doing this by the use of biofuels. The

coal-fired powerplants‚ or heating our homes with oil or natural gas‚ all have devastating affects on our environment. One of those affects is global warming. There are people who dispute the effects of global warming‚ but scientist have proven that levels of Carbon dioxide in the atmosphere have increased by over 10% since 1950‚ while average temperatures have risen by over 0.5°C/1°F in the same period (n.d. Global Warming and the Greenhouse Effect). What is global warming? Global warming is the

attributed to the greenhouse effect caused by increased levels of carbon dioxide‚ CFCs‚ and other pollutants. Climate change is any substantial change in Earth’s climate that lasts for an extended period of time. Global warming refers to climate change that causes an increase in the average temperature of the lower atmosphere. Global warming can have many different causes‚ but it is most commonly associated with human interference‚ specifically the release of excessive amounts of greenhouse gases. (EPA

article back to what I have learned in class is by mentioning the greenhouse effect. The greenhouse effect is where the sun radiates down on Earth’s surface‚ which is absorbed by the surface and is turned into heat. That radiation then radiates back out towards our outer atmosphere and is then absorbed by the gases in our ozone layer. This is the natural greenhouse effect‚ but the world has created something called enhanced greenhouse effect. Enhanced green house effect is where we have emitted so
