The countries and the world at large are facing many different crises currently. Different experts have come up with ways to predict the occurrence of different crisis in the near future. These predictions are important as they may give out information on how to prevent or overcome the crises, which mostly have adverse effects such as loss of lives or affect other crucial phenomena. I am going to cover predictions about climate change.
Summary
Climate change refers to the increment in global temperatures. There are several factors that lead to climate change such as natural events and human induced activities. The key cause of climate change is the increase in greenhouse gases like Carbon Dioxide (Hegerl, Gabriele et al., 832). Carbon dioxide is responsible for 64% of the global climate change. This amount is 40% higher than before industrialization began to take effect. Between 1700's to early 1900's industrialization was low. The rate of industrialization is increasing across all countries of the globe resulting to increase of greenhouse emissions and eventually leading to increased climate change globally. On a normal scale greenhouse gases are life enabling, however, increase in the emissions especially from the steady developing of industries leads to more trapped head hence leading to climate change such as fluctuations in amount of precipitation.
Many machineries use different sources of energy to run such as coal, oil and gas. The burning of this sources produces large amounts of carbon dioxide which is released in to the atmosphere. Between the early 1900's and 1950's there were very few machineries. Very few people have adopted the use of safe sources of energy such as biodiesel, electricity, solar energy and wind (Houghton, Theodore et al. 644). This sources do not produce any form of emissions that cause harm to the atmosphere. Only 27% of the people living in the U.S use safe sources of energy in their activities while the rest 73% use sources of energy that can cause harm to the atmosphere through climatic change like reduction in ice and snow cover of the mountains and rise in the sea level because of an increase in heat.
A large part of the earth is covered by water and a small portion by land and on land there are areas with forests. However, Deforestation is increasing each year as people cut down trees to make furniture and as a source of heating in homes. The rate of deforestation has gone up by 45% since 1997. Others clear forests to make room for expansion of buildings and towns. All of this activities create an imbalance in carbon dioxide as trees regulate the amount of carbon dioxide as they use carbon dioxide during photosynthesis to make their food. Less trees result to increase in carbon dioxide levels in the atmosphere, causing the greenhouse effect and climatic change like leading to increase in the average temperature of the earth.

Regions conducting livestock farming produce large amounts of methane, which is a greenhouse gas and is emitted into the atmosphere and causes the greenhouse effect that leads to climate change. Also farming using fertilizers that contain nitrogen produces nitrous oxide emissions, which cause greenhouse effect and climate change, causing an increase in level of acidity in the oceans (Intergovernmental Panel on Climate Change, 1655).
In the 1940's to 1980's, the level of industrialization was low, there were very few industries per country and on a global scale. Back then there were no cases of melting of polar ice caps or rise in sea levels. The atmosphere and its phenomena were stable. With the development of industrializations complications began occurring such damage to the Ozone layer because of the waste gaseous emissions. More industries are being set up currently meaning that there will be release of more emissions, hence adverse effects of climatic change.
Currently, the number of vehicles on the road is too high and most of them use gas. Exhaust fumes from these vehicles and other machineries, like diesel generators release fumes into the atmosphere. In the 1920's there were very few vehicles and also no cases of greenhouse emissions. With current civilization there more cars and more are being made indicating more emissions in future that may lead to adverse climatic changes
Deforestation is increasing drastically in many countries leading to the government coming up with policies to prevent deforestation such as permits for people who want to cut trees, replacement of cutting down one tree by planting several and creating regions such as forest reserve to protect trees from being cut by people. This shows that people are aggressively after cutting trees and if not effectively controlled there will be few trees and more carbon dioxide creating an imbalance that causes climatic change.
Strengths
Most of the effects of climate change are brought about by human activities. The activities done by human beings are what brings about such as the creation of many industries which means more areas will be affected by greenhouse emissions. If humans embrace the use of the safer sources to run machinery such as solar, wind and electricity there will be no emissions, hence, a safe climate condition in the world.
Limitation.
It is difficult to control the waste of large heard of livestock like in cases of ranches where the area the livestock are kept is vast. There will be the release of the methane into the atmosphere causing climatic change. Reduction in the number of livestock to reduce emission may lead to a country's food shortage.
