Climate Change

Climate Change

The average weather pattern of the certain area experienced over a long time is called climate. The climate is positive towards human, animals, plants and physical structure. If there is an imbalance in the climate then we can say that there is climate change. Climate change is the change in the statistical distribution of the system of weather when that change lasts for a long time period. For example: - if the monsoon rain occurring in Asar does not occur till Jestha or Shrawan, if the climate is hot till Mangsir or cold till Baishak, etc. are climate change. The main reason for the climate change is the increase in the amount of carbon dioxide in the atmosphere. This gas increases the greenhouse effect in the earth. This increases the temperature of the earth and thus, brings imbalance in the climate. We, ourselves, are the main reason for the climate change. So, we should bring effective ideas for its solutions.

In 1830 AD, there were only 281 PPM (parts per million) atoms of carbon dioxide per ten lakhs atoms of air. In 2010, the amount increased and reached 390 PPM. The temperature of the earth increased up to 0.740C in comparison to the temperature of 1901 AD. If the temperature increased in the same way then, it is predicted that the temperature of Nepal would increase by 1.40C in 2030 and by 3 to 6.3 degree in 2090 AD. In coming few years, the snow of our mountain would melt and only the rocks would remain. The settlement in coastal areas would sink. So, we should decrease the production amount of the gases that increases the temperature.
