GLOBAL DAMAGE DUE TO CLIMATE CHANGE 

 Climate change is driving fundamental changes to the planet with adverse impacts on human livelihoods and well-being, putting development gains at risk. The scale and extent of future risks for a given location is, however, subject to uncertainties in predicting complex climate dynamics as well as the impact of individual and societal decisions that determine future greenhouse gas emissions as well as patterns of socio-economic development and inequality.

The report approaches climate-related losses and damages from a risk management perspective. It explores how climate change will play out in different geographies, over time, focusing on the three types of hazards: slow-onset changes such as sea-level rise; extreme events including heatwaves, extreme rainfall and drought; and the potential for large-scale non-linear changes within the climate system itself. The report explores approaches to reduce and manage risks with a focus on policy action, finance and the role of technology in supporting effective risk governance processes. Drawing on experiences from around the world, least developed countries and small island developing states in particular, the report highlights a number of good practices and points to ways forward.

 Global warming refers to climate change that causes an increase in the average of Earth’s temperature. Natural events and human influences are believed to be top contributions towards the increase in average temperatures. Global warming is a rise in the surface and atmospheric temperature of the earth that has changed various life forms on the earth. The issues that ascertain global warming are divided into two broad categories – “natural” and “human influences” of global warming.

The climate has been continuously changing for centuries. One natural cause of global warming is greenhouse gases. Greenhouse gases are carbon monoxide and sulphur dioxide. It traps the solar rays and prevents them from escaping the surface of the earth.

This causes an increase in the temperature of the earth. Volcanic eruptions are another reason for global warming. A single volcanic eruption can release a great amount of carbon dioxide and ash to the atmosphere. Increased carbon dioxide leads to a rise in the temperature of the earth.

Also, methane gas is another contributor to global warming. Methane is also a greenhouse gas. Methane is twenty times more effective in trapping heat in the atmosphere than carbon dioxide. Usually, methane gas is released from many areas like animal waste, landfill, natural gas, and others.

Human influence has been a very serious issue now as it is contributing more than natural causes of global warming. Since human evolution, the earth has been changing for many years until now and it is still changing because of our modern lifestyle. Human activities include industrial production, burning fossil fuel, mining of minerals, cattle rearing and deforestation.

Industries, transportation such as cars, buses, trucks burn fuel to power machines, which eventually releases carbon dioxide and monoxide from the exhaust, leading to an increase in a temperature rise of Earth’s atmosphere.

Another contributor is mining. During the process of mining, the methane gas trapped below the earth escapes. Rearing cattle also causes the release of methane from manure. Another cause is the most common but most dangerous – deforestation.
