Are humans definitely causing global warming?
It is important to understand the following key aspects of Global Warming:. But the Climate Change trend in the past century and the current century is so out of proportion that it has threatened and disturbed this Harmonious Balance and the Equilibrium state. So these are not a part of the Natural, Internal heating-up and cooling-down trends of the Climate System. Some of the major potential External Factors have been analysed to be the following:.
And they have come to some mutually agreed Conclusions about the relative roles of these External Factors, as explained below. By general Consensus, this is considered the Single most important and biggest causative factor for Global Warming. The story of Global Warming starts with the very fact that the Earth gets heated up.
So this heating-up called the Greenhouse Effect is vital for creation and maintenance of Life on the Planet Earth. There are some very specific activities that are mainly responsible for this. These can be related to natural process or to human activity. It has been statistically proven by various International Bodies that the Greenhouse effect can be attributed to the Human Activity in the post-Industrial period.
Volcanic activity and eruptions inject huge amounts of Volcanic gases, Aerosol droplets and Ash into the atmosphere. It was a topic for research and analysis as to what is the role of the Volcanic gases and Aerosols in the Global Warming phenomenon. Over years of scientific research, it has been proven that the role of Volcanic Activity in Global Warming is of minimal significance.
Volcanic gases include elements like Sulphur-di-Oxide [SO2], which causes atmospheric cooling, and also Carbon-di-Oxide [CO2] which causes atmospheric heating. But it has been proven that only a fraction of a percent of these gases and Climate Change are contributed by Volcanic activity as compared to the Greenhouse effect due to human activity. Global Warming and the wider phenomenon of Climate Change has grown to epic proportions in the last decade. The frequency of the heavy precipitation has lead to the greater prevalence of floods.
Global warming creates more natural disasters. Extreme weather events will continue to occur with greater intensity. So, we will experience significant changes in seasonal temperatures variations, wind patterns, and annual precipitation. The effects of global warming on plants and animals are expected to be widespread and profound.
Many organisms are migrating from the equator toward poles in order to find more comfortable conditions for their existence. However, a lot of animals go extinct as they are not able to compete in new climate regime. The effects of climate change due to the global warming can be devastating to the human society.
People can face severe crop failures and livestock shortages that will cause civic unrest, food riots, famines, and political instability in the whole world. Global warming threatens our future health conditions. Humanity will experience an increase in tick-borne and mosquito-borne diseases.
What is more, people have become more vulnerable to extreme weather and climate changes that lead to serious mental health issues. The sea-level rise accelerates 0. This trend will continue if gas emissions remain unchecked. People are to blame for rapidly melting ice, warming oceans, and rising sea levels. Coral reefs are in danger as the ocean warms. Two-thirds of the Great Barrier Reef has been damaged as a result of climate change.
Global warming increases the acidity of seawater because of the increase of the levels of CO2. The ocean is 26 percent more acidic than before the Industrial revolution. Melting glaciers endanger human life on the coastal areas. It can cause landslides and other land collapses. Increase in average temperatures is the major problem caused by global warming.
Essay on Global Warming for Students
The average global temperature has increased by about 1. Such temperatures turn our environment into a breeding ground for infections and diseases. The worst thing is that increased dryness and greenhouse gases serve as natural fuels for wildfires. Scientists have predicted the effects for the future based on the climate changes due to the global warming problem.
Snow cover is projected to contract. Sea ice is projected to shrink in both Antarctic and Arctic. Future tropical cyclones will become more intense.
Heavy precipitation events, heat waves, and hot extremes will become more frequent. Arctic late-summer sea ice can disappear by the end of the 21 st century. Sea level rise and anthropogenic warming will continue for centuries.

Is global warming man-made?
Just think, there is more carbon dioxide in the atmosphere today than at any point in the last , years. Air quality is affected greatly by the global warming. The air pollution caused by overabundance of carbon dioxide, vehicular emissions, and power plants influences the human respiratory system. A lot of people all over the world suffer from respiratory diseases. The surface of our planet can warm by 6 degrees this century. Information that will make your essay even more interesting and catching The Arctic is one of the worst places affected by global warming.
More than 1 million species have become extinct due to the effects of global warming. The Montana Glacier national Park has only 25 glaciers instead of that were there in the year Human activities release around 37 billion metric tons of carbon dioxide per year.
