Decaying trees are one major source of natural CO2 emission. Whether the tree is dead and rotting or burnt, it will produce the same amount of CO2.

The ocean, which is also the number one method of removing CO2 from our atmosphere, is also a supplier of CO2.

Byproducts of animals existence also contribute to the total greenhouse gas mix.

The sun is also a contributor, not only through solar variation, but through the interaction with oxygen to create ozone. Ozone is a very strong greenhouse gas. The cooling that we see in the Antarctic has been blamed on a thinner ozone layer, just to show you the intensity of this gas.

The overwhelming consensus among climate scientists is that human activities, such as the burning of fossil fuels and deforestation, are the primary drivers of global warming. Multiple lines of evidence, including the increase in greenhouse gas concentrations in the atmosphere and the correlation between human activities and rising temperatures, support this conclusion. Any arguments against human-caused global warming are based on cherry-picked data or flawed interpretations of scientific evidence.

Not really. The Northwest Passage is mostly free of ice during the summer months, something that has not happened for a very long time. Global Climate Change is real and it's caused by the burning of fossil fuels by human beings. Volcanoes have not had this long term effect on the climate for thousands of years. Previously a big volcanic eruption could change the climate for one or two years, but, nothing like we are seeing now.

No. The world was going along comfortably warm for millions of years, thanks to the natural carbon cycle and water cycles which move carbon dioxide and water in and out of the atmosphere all the time. These greenhouse gases contribute to the normal greenhouse effect.

Then at the beginning of the Industrial age, about 250 years ago, humans started burning fossil fuel, coal, oil and natural gas. This released carbon dioxide that had been stored underground for millions of years. This extra CO2 has been too much for the carbon cycle to deal with and has produced the accelerated greenhouse effect, which is causing global warming.

Global warming IS being caused by humans. There is no other possible reason. The warming is happening too fast to be natural (warming after an ice ages takes tens of thousands of years).

We know greenhouse gases capture heat. We know that burning fossil fuel adds extra greenhouse gases to the atmosphere. We know we have cut down the forests that used to store billions of tonnes of carbon.

We are the cause.

Reasons against humans causing global warming?

The earth has a long history of warming and cooling. Ever heard of the Ice Ages? Other planets are currently showing evidence of warming.


How Many scientists don't believe in global warming?

The overwhelming consensus among climate scientists is that global warming is real and primarily caused by human activities. While there may be a small minority of scientists who question the extent or causes of global warming, the consensus and evidence supporting the reality of climate change are robust.


How are you responsible for global warming.what do we do that causes global warming?

well there are a lot of reasons that we cause golbal warming. The main one I can think of is every time that you plug something in. I believe that global warming is not being caused by humans. There are just as many scientist saying that it is not happening than there are saying that it is.


Is global warming originally caused by plate tectonic shifting?

No, global warming began when humans seriously started burning fossil fuels in the Industrial Revolution, adding additional greenhouse gas (carbon dioxide) to the atmosphere.


What does the documentary The Great Global Warming Swindle say about global warming?

The documentary "The Great Global Warming Swindle" questions the mainstream scientific consensus on climate change by arguing that natural factors, rather than human activities, are primarily responsible for global warming. It suggests that evidence supporting human-caused climate change is exaggerated or manipulated to push a political agenda. The documentary has been widely criticized by the scientific community for cherry-picking data and misrepresenting the consensus on climate change.

If we wern't here would global warming happen?

No. Global warming is caused by man burning fossil fuels and cutting down forests. No other animal does that. If there were no humans on earth, there would be no global warming.
