Climate change has been occurring over the decades but it is just getting worse and more greenhouse gases are getting trapped in the atmosphere and trapping heat energy from the sun along with it. If humans are so small and can create a mess so big we can clean it up too because it is evident that humans have caused an increase in chemicals and pollution that has altered the chemical composition of the atmosphere which ultimately causes the climate change we see
Do humans cause global warming or is it natural? Many researchers, scientists, and environmentalists are expressing concerns about changes in the overall climate of the `earth. Some believe that a dramatically dangerous warming is taking place in the overall global climate, a problem that is referred to as "global warming”. What is global warming? Global warming is an increase in the average temperature at Earth's surface (“global warming”).
It’s rather obvious that human causes are more vulnerable compared to natural causes. Natural causes are normally external to the climate system, such as changes in volcanic activity, solar output, and the Earth 's orbit around the Sun. On the other side, climate change that are caused by human activities, are such as the burning of fossil fuels and also the conversion of land for forestry and agriculture. Not only that, carbon dioxide is also one of the main cause of human-induced climate change. Ever since the Industrial Revolution, the production of carbon dioxide which is a greenhouse gas has been increasing tremendously.
The main cause for climate change is human activities According to NASA the global sea level rose 8 inches since 1880 and the sea level will rise another 1 to 4 feet in 2100 The cause is climate change which causes expansion of sea water as it warms and added water from the melting ice sheets. Of course this isn’t the only effect that climate change has on earth , climate change is the change of earth overall climate or earth average temperature which has risen by 1.7 degree Fahrenheit since 1880 which may not seem a lot but it can have big effects like the increasing sea level , what is the cause ? It’s called the greenhouse effect , in a greenhouse the heat is trapped by the glass , earth is a greenhouse , gasses
Earth has been shaping, changing, and warming for many years, but the increase in modern and advance life on Earth is doubling the cause of global warming. Records show that the earth is warming faster. The cause of this is heated trapping chemicals that humans are releasing into our
Topic : Human activities have been a major cause of climate change . To what extent do you agree or disagree ? In modern life , human beings have been undergoing climate change , which is defined as a change in the pattern of weather and related changes in oceans , land , surfaces and ice sheet by Australia Academy of science . There is undeniable fact that the modern world has to encouter challenges concering climate change such as the higher average temperature , more droughts, wilder weather and shrinking ice sea . it is firmly believed that natural causes involving vocalnic eruption , ocean current , solar variation and the earth 's orbital change are primarily responsible for substantial climate change .
Many experts attributed the root cause of climate change to human activities that comes with the rapid growth of the global economy including human consumption of different sources of energy, rapid rate of deforestation and bush burning. The negative impacts of climate change on crop production, higher average world temperature, rising sea levels, reduced rainfall, amongst others are largely indisputable in the literature. A high taxes on carbon-intensive fuels like coal could reduce their consumption and hence carbon
The earth is warming. Earth’s average temperature has risen by 1.4F over the past century. This has affected the worlds climate and the ecosystem we live. Many places have seen changes in rainfall, resulting more floods, drought, or intense rain as well as more frequent and severe heat waves. Oceans are warming and becoming more acidic, ice caps are melting and the sea levels are rising.
“The theory of human activity (fossil fuel burning) being a direct cause of global warming is based on the assumption that atmospheric carbon dioxide concentration is directly related to global warming. Is this assumption valid?” Global warming is brought about by the greenhouse effect. The greenhouse effect Gasses in the troposphere cause the greenhouse effect. There is a correlation between the temperature of the earth and the concentration of carbon dioxide in the troposphere, however, correlation does not infer causality. The earth receives energy from the sun in numerous wavelengths.
Many believe that humans have increased the concentration of energy-trapping greenhouse gases in the lower atmosphere, therefore impacting the Earth’s natural greenhouse effect (McMichael, 2003). Maqbool (2013) supports that greenhouse gases emitted from land-use change and burning of fossil fuels add to the climate change, but admits that they do not solely cause it. He argued that water vapour is the primary greenhouse gas and the high solar activities of the sun itself would result in elevated temperatures on Earth (Maqbool, 2013). Research by the US Global Climate Research Programme (Alaska Regional Assistant Group) highlights that global climate change has the potential to affect tropic levels and human health by means of food chains (McMichael, 2003). Maqbool (2013) debated that melting of glaciers is not a consequence of global warming, but occurs as a result of drifting of tectonic plates.
