Global warming is generally thought of as real. Is what scientists do not agree about is why global warming is occurring.
Some scientists will say that global warming is a naturally occurring event and it is something that is going to happen regardless of the actions of humans. They will also say that global warming has occurred many times in the past.
Most scientists will argue that global warming is a result of humans and our impact on the environment. Global warming can be reduced by altering what we do to the environment. Some examples of how this can be done is by using alternate forms of fuels that are less damaging to the environment, recycling, and saving energy.
I agree with the previous post. I am not entirely certain that there is a debate about the Earth's temperature being on the rise. The political and social dimension to this problem might be where the debate is. The fact is that there is a rise in water level, a melting of the ice caps, and a general increase in the temperature of the planet. Most would not debate that there has not been change. The question becomes whether this is made by humans or rather a natural condition of existence. If the warming pattern is a natural condition of existence, then the political debate takes a rather big turn in that human beings are kind of absolved of their role in this predicament. This impacts environmental regulation, green initiatives, as well as basic elements of what individuals can do in this process. For example, no matter what humans do, if warming is a natural condition, then it is almost inevitable that there will be a rise in the Earth's temperature. If it is something where humans can play a role in the process, then the focus becomes what can we as humans do and what initiatives and laws can be passed in order to do it. I think that this is where most of the debate is, as opposed to whether or not this problem is present.
As I understand it, the consensus among scientists is that global warming is real. In fact, there is little dispute on this issue. The EPA, for example, says that the temperature of the Earth has increased by about 1.2 to 1.4 degrees Fahrenheit in the last 100 years. This is not really in dispute.
What is disputed is WHY this is happening. Most scientists believe that the warming is coming about due to human activity. Specifically, they believe that it is caused by the release of "greenhouse gasses" into the atmosphere.
Howeber, many people do not believe this. They argue that the increase in temperature is a natural occurrence. The Earth's temperature has changed at times in the past (giving us ice ages, for example) and people argue that it is simply doing this again.
Global warming refers to the gradual change in the average temperature on the surface of the earth since the beginning of Industrial revolution. This kind of global warming which is mainly due to human activities such as industrialization as deforestation threatens to create major disasters at global level. The rise in global temperature, unless controlled will result in next few decades melting of polar caps increasing the level of oceans and submerging land area that is home to nearly 15 percent of world population. It may also cause increase in area of subtropical deserts.
One of the major causes of global warming is greenhouse effect. This refers to increase in the concentration of certain polluting gases such as carbon dioxide in the atmosphere which damages the protective shield in the upper atmosphere which prevents most of the ultraviolet rays from the sun reaching the earth's surface and prevents cooling of earth by radiation.
Most of the countries in the world have taken not of global warming as a threat to the entire globe and are trying to collaborate on ways of reducing pollution causing it, and in this way avert the disaster.
From the research that I have read, yes, global warming is real.
We are creating more greenhouse gases by the increased use of fossil fuels, such as oil and coal. Another area that we could control is the cutting down of trees. Trees naturally process the C02 (Carbon Dioxide) in the air to reduce the greenhouse gas. Since we are cutting trees to make room for homes, commercial development, furniture or paper, we are working against this natural processing unit.
So what can we all do? Use less water, gas in our cars, electricity by turning off unused or resting (i.e. computers) electrical items and PLANT a tree!
