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.
Water vapor is a greenhouse gas in the atmosphere that is not increasing as a result of human activity, or any other reason.
Deforestation and the burning of fossil fuels (coal, oil and natural gas).
No! The greenhouse effect is a natural effect that has kept the earth warm enough for life for millions of years.The enhanced greenhouse effect, which we have now, is the result of human behaviour, namely, deforestation and the burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases additional carbon dioxide. This greenhouse gas is building up in the atmosphere causing global warming.
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).
No. The greenhouse effect is the process by which certain gasses, called greenhouse gasses, help to trap heat within Earth's atmosphere. This effect has been in place for as long as Earth has had an atmosphere and is necessary for life to exist. Without it, the planet would freeze over. Global warming is primarily the result of an enhanced greenhouse effect, caused by extra geenhouse gasses entering the atmosphere.
The Earth has always has a greenhouse effect, it has kept our planet warmer than it should have been given its albedo and distance from the sun. The present concern is due to the enhanced greenhouse effect caused by the emission of carbon dioxide and a limited number of other gases into the atmosphere due to human activities.
Even if it were possible, we should not try to eliminate the greenhouse effect entirely - the result would be for temperatures to fall well below freezing and make it difficult for humans to survive. We need the natural greenhouse effect that keeps the world at a comfortable temperature suitable for human existence. It is probably too late now to eliminate the enhanced greenhouse effect resulting from two centuries of human activities that poured carbon dioxide and methane into the atmosphere. What we can and should do is to begin now to reduce our further emissions of greenhouse gaes, so that later in this century we can eliminate any anthropogenic addition to the greenhgouse effect.
Not solely. There is a natural greenhouse effect that is supported by the earth's carbon and water cycles. This has kept the earth warm enough for life for millions of years.However, 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 causing global warming and climate change.
Carbon dioxide and methane. Human activity is releasing more and more of these gases from the burning of fossil fuels (coal, oil and natural gas) and deforestation (cutting down trees which previously removed carbon dioxide (CO2) from the atmosphere).So the natural greenhouse effect that has kept the earth warm for millions of years is being enhanced into an accelerated greenhouse effect.

The Greenhouse Effect is real. There is no question that the presence of CO2 and other greenhouse gases keeps this planet comfortably warm. The alarming crisis of Global Warming arises from the ever-increasing concentrations of greenhouse gases in our atmosphere as a direct result of human activity. All of the science suggests that increasing greenhouse gas concentrations will inevitably lead to a rise in global temperature. How much and how quickly temperature will rise is disputed. Nonetheless, as scientists and citizens, we have a responsibility to act now, to educate and work towards changing our habits and our impact on the planet. thanks................
The effect of human activity is negative against nature (including parrots).
