Is human activity the main cause of climate change?
Human activity is the main cause of the present climate change. Burning fossil fuels and deforestation mean that the amount of greenhouse gas in the atmosphere has been gradually increasing since the start of the Industrial Revolution. This is causing an accelerated greenhouse effect, which is global warming, and this is causing climate change.
How have human activities changed the greenhouse gases?
Human activities like burning fossil fuels (coal, oil and natural gas) and deforestation have increasedlevels of greenhouse gases.
What is the main energy source that drives global warming?
The main energy source for global warming is the sun. The warmth that reaches us from the sun is trapped by the naturally-occurring greenhouse gases, to maintain a comfortable temperature suitable for human habitation. The recent rise in greenhouse gases, resulting from human activity, causes more of the sun's heat to be trapped, resulting in global warming.
Which human activity is MOST likely to be a contributing factor in global warming?
A:Generating electricity from fossil fuels is the one human activity that contributes more than any other to increased atmospheric greenhouse gas levels and is therefore considered to be the main contributing factor in global warming. Thus, any human activity that creates an increased demand for electricity is effectively contributing to global warming. Next comes motor transport, because this requires us to burn oil, one of the main fossil fuels.
Greenhouse gases- how do they affect us?
Greenhouse gases have been working with the heat from the sun to keep the earth comfortably warm for millions of years. The gases absorb some of the heat from the warmed earth and keep it from escaping into space. When greenhouse gas levels increase, as they are from recent human activity, they retain more heat and the earth warms up.
What greenhouse gas is not currently increasing?
Water vapor is a greenhouse gas in the atmosphere that is not increasing as a result of human activity, or any other reason.
Do greenhouse gases occur naturally in the air?
Yes. Most of the greenhouse gases do occur naturally, particularly carbon dioxide (CO2). By maintaining the temperature that we enjoy today, these gases are essential to life on earth as we know it, as long as the concentrations of the gases do not rise or fall appreciably. In the absence of human activity the concentrations of greenhouse gases remain more or less constant over time, so that there is no effect on global warming. However, when human activity results in even a small increment in the concentrations of greenhouse gases, we begin to get global warming and climate change.
What human activity contributes to the greenhouse effect?
Deforestation and the burning of fossil fuels (coal, oil and natural gas).
Is human activity the main cause of climate change?
Human activity is the main cause of the present climate change. Burning fossil fuels and deforestation mean that the amount of greenhouse gas in the atmosphere has been gradually increasing since the start of the Industrial Revolution. This is causing an accelerated greenhouse effect, which is global warming, and this is causing climate change.
Why is water vapor not considered to be a greenhouse gas?
It is not possible to regulate water vapor as it mostly occurs naturally.Water vapor is a greenhouse gas, in fact, it is the one that causes the most global warming (up to 70%). However, water vapor is hardly at all caused by human activity, so it is not possible to regulate it. The next most potent gases, carbon dioxide, methane and ozone can be altered by human activity.
What is the biggest thing that can affect the greenhouse effect?
The greenhouse effect is mostly caused by human activity such as deforestation and burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide (CO2).
When happens greenhouse effects?
the greenhouse affect all human life.
Does the greenhouse effect result from human activity?
Yes. Humans have been burning fossil fuels since the beginning of the Industrial Age (1750s). This releases long-held carbon dioxide that has been sequestered away for 300 thousand years. This extra greenhouse gas is changing the greenhouse effect into an enhanced greenhouse effect, which is getting warmer and warmer.
When do greenhouse gases become a problem?
Some would say that greenhouse gases are already a problem, contributing to human-caused global warming. Others would say they are not yet a problem and may never be. That is one of the main points of dispute on the issue of whether there is a problem of global warming caused by human activity.
Which gas is mainly responsible for the greenhouse effect?
The greenhouse effect contains two different components: the natural greenhouse effect, and the enhanced greenhouse effect that results from human activities and is the cause of global warming.Water vapour is the most plentiful greenhouse gas and is mainly responsible for the natural greenhouse effect that maintains the world at a comfortable temperature suitable for human existence. Carbon dioxide also plays an important part in this natural greenhouse effect.Carbon dioxide is mainly responsible for the enhanced greenhouse effect. In this case, water vapour plays only a minor part as an enhancer, because the atmospheric concentration of it will increase if the temperature rises for other reasons, then causing a further increase in temperatures.
What human activities could cause a tornado?
There is only one human activity that might influence tornadoes, but it does not cause the on an individual scale. Many have claimed that rising temperatures due to human greenhouse emissions has led to or will lead to an increase in tornado activity. This needs more looking into, however, as scientists are still no sure how increasing global temperatures will affect tornadoes.
How do greenhouse gases pollute the world?
Greenhouse gases are gases that help trap the sun's warmth in our atmosphere and maintain the temperature that we enjoy today. The greenhouse effect is essential to life on earth as we know it. Thus it is a misunderstanding to regard them as pollutants. Most of the greenhouse gases are colourless, odourless and, in themselves, harmless. However, a slight increase in the amount of greenhouse gases in our atmosphere would result in global warming and climate change, while a slight reduction in greenhouse gases would result in global cooling. In the absence of human activity, the amount of carbon dioxide, the most abundant greenhouse gas, remains relatively constant over a long period of time. There is, of course, a recycling of carbon to carbon dioxide and back, as plants take in carbon dioxide, convert it to organic matter, then die and decay (or are burnt in forest fires), once again giving off carbon dioxide, but this is a natural cycle and does not alter the concentration of carbon dioxide in the atmosphere. It is because of human activity that results in increasing concentrations of greenhouse gases that we are now beginning to experience global warming and climate change. However, this is not pollution in the normal sense of the word.
