Science is a way of understanding nature by using observation and reason. Man has always been keenly interested in the weather, but temperature records before 1850 were mostly historical accounts of storms, heat waves, or when bodies of water froze. Thermometers came into use in about 1850, allowing more accurate temperature records. One of the [...]

Let us understand what greenhouse effect is all about. The main source of light and natural energy to earth is sun. Almost half of the sun’s energy in rays is absorbed by earth’s surface. Earth in return, radiates back this energy in form of infrared rays. Now, when this heat is absorbed by greenhouse gases [...]

The amount of greenhouse gases in the atmosphere has increased and this is one of the major factors that have contributed to global warming. Green houses like carbon dioxide, methane, chlorofluorocarbons and carbon monoxide trap the infra red radiations from the sun and ensure that the earth is hospitable to various living species. In fact, [...]

To prevent Global warming, one of the things that a person can opt for is use of alternative forms of energy production other than fossil fuels which give large amounts of carbon dioxide. Use of solar energy can be a good alternative which can be employed. Another thing they can do is to plant trees [...]

You can do things to prevent the devastating changes that are occurring in our environment. Global warming is a term that is frequently used to describe the rising temperatures that are occurring in our world. Lately, this has seemingly grown in popularity. It has been found that it can produce many negative reactions in our [...]

The main effect centres around an increase in the global average temperature. It’s been confirmed by at least 20 scientific societies and academies of science, as well as all the national academies of science of the G8 states, that the Earth’s global average air temperature near its surface rose by 0.56-0.92 C (0.98-1.62 F) degrees [...]

The upcoming climate change summit in Copenhagen in December where the leaders of the world are going to meet is an ideal place to start the process of addressing the core issues that are part of the global warming debate. It is rather befitting that Copenhagen in Denmark that is in Europe should be selected [...]

Data of NASA shows that the trend in the Earth’s temperature has been mostly upward and that the Earth is now about 1.3 °F warmer than it was a century ago. Scientists point to an increase in greenhouse gases from fossil fuel use as the major cause, but skeptics claim the warming observed is natural. [...]

There are also natural ways that eart warming occurs, so it cannot all be completely blamed on humans. It is not very likely that people can put an end to the natural things that contribute to this warming. Although, we can make a huge difference by stopping activities that make global warming happen faster and [...]

The temperature of Earth may have increased between 2 degrees F and 11.5 degrees F when 21st century comes to a close. This temperature increase is mainly due to two reasons. Natural phenomena such as volcanoes, radiation from the sun, methane release are the first cause and the mistakes committed by people like deforestation, injudicious [...]
