Dr. Rajesh Rajora Views On Climate Change

In the decade, the problem of climate change has become the focus of a great deal of scientific community. Weather patterns, extinction of many species, and other significant global-scale events are directly correlated with climate change.

According to Dr. Rajesh Rajora, our atmosphere consists of gases that stop the heat from getting close to the surface of the earth. The water vapor with some small amounts carbon dioxide which is the layer of greenhouse gases, serve as the Earth's thermal blanket.

To understand the reasons of climate changes, it is important to understand paleo climatologists as well as the present conditions that influence the climate. Pollution is a major factor to climate change, including global warming, because of the emission of carbon dioxide.

These are possible reasons of climate change:

• Earth’s temperature is a balancing act
• The Greenhouse Effect causes the atmosphere to retain heat
• Changes in the sun’s energy affect how much energy reaches Earth’s system
• Changes in reflectivity affect how much energy enters Earth’s system

The main greenhouse gases include:

• Water vapour
• Carbon dioxide (CO2)
• Methane
• Nitrous oxide
• Chlorofluorocarbons (CFCs)

Climate change simply refers to the long and lasting changes in weather patterns. It is also referred to as the AGW or the anthropogenic global warming. The problem is that pollution from industrial factories, operating vehicles and other equipment that requires burning fossil fuels like oil, coal, and gas produces additional amounts of carbon dioxide. Carbon dioxide along with methane, nitrous oxide, hydro fluorocarbons, perfluorocarbons and sulfur hexafluoride are known as greenhouse gases.
