Global warming is one of the biggest problems that human beings have ever experienced. This problem has numerous negative impacts on our health and economy . Therefore, it seems necessary for us to find ways to tackle this problem.
First of all, we should know the clear definition of global warming.
According to “Annex II Glossary” Intergovernmental Panel on Climate Change (IPCC), Global warming is a phenomenon that is caused by increas in Earth’s average surface temperature because of the effect of greenhouse gases such as CO2, which prevents heat to escape from the Earth.
Because global warming has so many catastrophic results on environment, it is important to identify the reasons for it and realize how to combat this phenomenon . The first reason is because of the greenhouse gases effect ; absorbing heat by these gases from the surface and the emitting it back to the surface lead to warming the the surface and lower atmosphere . Furthermore, scientists believe changes in solar radiation and variations in Earth’s orbit are other reasons.

Scientists have realized some practical ways to combat this unsolved issue.
Reducing tropical deforestation can have a significant effect in lowering emissions that are the causes of global warming. Because CO2 is the most important greenhouse gas, stopping deforestation and planting trees can have a major effect on reducing the global warming. This is due to the fact that plants take carbon dioxide in and then release oxygen to their environment. Therefore, planting new trees could be a positive approach.

Another solution to global warming is reducing the waste that we produce. Disposal of waste can produce combination of several greenhouse gases that are the main reasons for climate change. For example, methane that is one of the most important greenhouse gases which is produced when organic matters decompose in landfills. Recycling items such as plastic, paper and glass can significantly reduces the amount of emissions .

Our personal cars are considered to be the most significant source of the greenhouse gases that are in troposphere. For example, emissions from cars and trucks in The United States of America account for 20% of all emissions. So, we can contribute to reduce greenhouse gases in some ways including: travelling by public transportation and driving smart .

Since consumption of fossil fuels is the reason for releasing carbon dioxide and other greenhouse gases to atmosphere, it seems necessary to find other ways to generate energy. Renewable energies such as solar power, wind and geothermal heat are the most striking examples of clean and sustainable alternative energies. With using these energies, we can combat global warming by the reduction of carbon dioxide emissions.

By using mentioned solutions and the modern technologies that we have, we can reduce the amount of heat-trapping gases in the atmosphere.
