Modern Times

Climate change is of great importance in modern times and global warming is considered as a significant part of climate change. It is proved that human’s emissions such as greenhouse gases are one of the main sources of global warming (IPCC, 2018). Apart from greenhouse gases, there is another kind of matter being released in quantity via emissions from industries and transportations and playing an important role in global warming, which is aerosol. However, atmospheric aerosols have the net effect of cooling towards global warming. In this paper, climate change with respect to global warming is briefly introduced and the role of aerosols in the atmosphere is emphasized. Besides, properties of aerosols including dynamics and thermodynamics of aerosols as well as interactions with solar radiation are concluded. In the end, environmental policies and solutions are discussed. Keywords: Climate change, Global warming, Atmospheric aerosols, Particulate matter, Radiation, Environmental policy.

Emission Of Greenhouse Gases

Abstract Pig slurry is classified as a natural liquid fertilizer, which is a heterogeneous mixture of urine, faeces, remnants of feed and technological water, used to remove excrement and maintain the hygiene of livestock housing. The storage and distribution of pig slurry on farmland affect the environment as they are associated with, among others, the emission of various types of gaseous pollutants, mainly CH4, CO2, N2O, NH3, H2S, and other odorants. Methane (CH4), carbon dioxide (CO2) and nitrous oxide (N2O) are greenhouse gases (GHGs) which contribute to climate change by increasing the greenhouse effect. Ammonia (NH3) and hydrogen sulfide (H2S) are malodorous gases responsible for the occurrence of odour nuisance which, due to their toxicity, may endanger the health and lives of humans and animals. NH3 also influences the increase of atmosphere and soil acidification. The article presents the environmental impact of greenhouse gases and odorous compounds emitted from pig slurry. Key gaseous atmospheric pollutants such as NH3, H2S, CH4, CO2 and N2O have been characterized. Furthermore, methods to reduce the emission of odours and GHGs from pig slurry during its storage and agricultural usage have been discussed.

Emission Of Greenhouse Gases

When a decision-maker faces a choice between alternatives of action in a situation of uncertainty, one speaks of a “game against Nature” when he/she faces no interaction with another player or group. In the process of global warming, mankind is the one player facing two alternatives: resilience or precaution. Not knowing fully the consequences of the increase in the emission of greenhouse gases on climate change or the implications of climate change for biological and social system, what action to take? If there were a global benevolent rule, he/she may decide to avoid the worst outcome. But global ecological policy-making requires the coordination among a large number of players, which open up the possibility of reneging as well as carries heavy transaction costs.

Emission Of Greenhouse Gases

Climate change is now a global issue and its impact on different sectors like water sources, biodiversity, health, livestock, and livelihood are already seen. Climate change is accelerating due to the emission of greenhouse gases produced by anthropogenic activities. Though Nepal’s contribution to greenhouse gases is negligible compared to developed countries, its risk to climate change is very high. Thus, it extremely important to understand the current scenario of climate change of Nepal. Hence, this article reviews and compares the published articles which studies the pattern and trend of climate change of the time period of at least 30 years. Most of the article shows increasing trend of temperature. According to the recent study, maximum temperature was found to be increasing by 0.05°C/year and minimum temperature was found to increase by 0.03°C/year. Though, the trend of precipitation in Nepal is not clear like temperature most of the studies have concluded increasing in monsoon precipitation in coming years.

The land surface is where humans live and where they source their water and food. The land surface plays an important role in climate and anthropogenic climate change both as a driver of change and as a system that responds to change. Soils and vegetation influence the exchanges of water, energy and carbon between the land and the overlying atmosphere and thus contribute to the variability and the evolution of climate. But the role of the land in climate is scale dependent which means different processes matter on different timescales and over different spatial scales. Climate change alters the functioning of the land with changes in the seasonal cycle of ecosystem growth, in the extent of forests, the melt of permafrost, the magnitude and frequency of disturbances such as fire, drought, … Those changes feedback into climate at both the global and the regional scales. In addition, humans perturb the land conditions via deforestation, irrigation, urbanization, … and this directly affects climatic conditions at the local to regional scales with also sometimes global consequences via the release of greenhouse gases. Not accounting for land surface processes in climate modelling, whatever the spatial scale, will result in biases in the climate simulations.
