2.) How can the interaction between charges be useful for humans?
Electricity is made by coal plants or natural gas powered plants. These plants throw immense power into an electrical grid that sends power to homes and businesses. The generation of power emits CO2 into the air and (supposedly - climate science doesn't know either. They have a hypothesis which has as many holes in it as a strainer does) causes global warming. I don't understand the 2nd part. Please explain.
Since some people seem to have difficulty understanding what climate change is let me sart by defining that. 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 volcanic eruptions, and human-induced alterations of the natural world; these latter effects are currently causing global warming, and "climate change" is often used to describe human-specific impacts.
However since your question is about electricity I am not sure if you asked the question in the right category. The facts in regard to AGW is that the generating of electricity is done for a large part by combustion of fossil fuels in power generating stations who dump the waste products, including CO2 into the atmosphere. CO2 is a greenhouse gas, that without greenhouse gases the earth average temperature would be 33C colder (a giant snowball) and that we have added 40% more CO2 to the atmosphere.
A second way to answer your question would be as follows; Electricity is a form of energy and we can use that to control the climate in our home quite precisely. Outside of our home we have less control but we can create wind to cool us a little on a hot day or heat us a little on a chilly day. In effect changing the climate in our immediate vicinity, however on a global scale this has little effect. The second part can be answered as follows. Electricity flowing through the wires generates a magnetic field we can use to drive this fan and the heat we can use to warm ourselves with.
Hope this helped.
Since the UN-IPCC has never bothered to define Climate Change, other than, "Climate Change is a change in climate," how do you know if anything be an agent of Climate Change?
You teachers should do their homework before they ask such an inane question. Scientifically, you cannot answer a question that has undefined components. Your teacher should know that.
I don't wanna do your homework for you but its kinda obvious. Coal powerplants displace forests can destroy natural habitat for wildlife. CO2 emissions cause global warming.
Not sure about 2)? Is it talking about electricity? which powers our society?
