Carbon dioxide is a greenhouse gas. The more of it there is in the atmosphere, the more heat will be retained, leading to warming. This has been known since the 19th century, and this is true though the proportion of CO2 in the atmosphere is relatively tiny, now four hundred parts per million, and though plants require to breathe CO2 to survive.
Burning fossil fuels produces CO2. Heat is released when the fossil fuel reacts with oxygen: for example, methane, CH4, plus O2 produces H2O plus CO2. Children are taught this at different ages, but a fifteen year old who will never be capable of a university degree will be capable of understanding this.
Volcanoes produce CO2, and a lake in Cameroon belched forth a vast quantity of it, killing all animal life nearby; but the amount produced by industry is orders of magnitude greater.
The Earth’s climate and atmospheric CO2 levels, have changed in the past. However, now, both are changing catastrophically quickly, with results such as increased bleaching of coral, species migrating to cooler habitat closer to the poles or higher up mountains, alterations in climate such as rainfall patterns, and species extinction.
Sea levels will rise as ice on land melts and warming water expands.
Most people are capable of understanding these facts, but some wilfully deny or obfuscate them.
There is a great deal of doubt about how the world will be affected in the future. How quickly sea level will rise and how climate round the world will change are uncertain, though scientists get better at making predictions as more data emerges. However, the basic facts, showing that climate change is a threat, are clear.
Burning fossil fuels has been an abundant source of cheap energy, fuelling the Industrial Revolution and producing a huge improvement in human living standards. Making the equipment to get energy from other sources, such as solar, wind and tide, has an environmental cost, and often that energy is more expensive than fossil fuel energy, especially if environmental degradation is not factored in as a cost. Obtaining energy in different ways causes other environmental damage, such as pollution, as well as CO2 release. There are complex political and economic arguments to be made, and for these decisions we need the best possible data.
There are political and economic arguments that humanity should continue burning fossil fuels for the energy. I would have more confidence in them if those arguing for fossil fuel use did not feel driven to lie about the basic facts.
There are climate-change denialists, who would claim there is doubt about the basic facts, or minimise the damage that fossil fuel use will do. Human beings are often selfish and irrational, failing to defer gratification, or denying facts which they find uncomfortable. However highly paid and educated people, or politicians, should be able to acknowledge the basic facts.
Well said and I’m in sync with you having just read and commented on Professor Taboo’s post here –

in which he has much to say on the subject himself.
Esme eyes wide open upon the Cloud waving at Clare.

Clare Flourish, some people claim that global warming is a hoax and some people claim it is a real problem. What are your thoughts?

See above.

Clare Flourish, I meant in the sense that aside from what you wrote as to what your thoughts were here what your thoughts are otherwise. Do you think global warming is as problematic as some people seem to think or that it is meant to instil needless panic among people? Also, people in denial about climate change-I am somewhat skeptical about that claim. Is it provable?

This is true. Global warming is a legitimate concern, however, acts of terrorism are also a great concern. Just my thoughts.

Environmental issues should be of concern to us all. However, some people seem to take the issue too far.

Nobody takes it too far. It is an existential threat.

True, however, in the United States, those who are to the Left on the political spectrum do not practice what they preach regarding environmental issues. These same people beef about the environmental problems, however, they use chemicals that cause damage to the environment.

Clare Flourish, obviously global warming would affect all of us, however, from an environmental standpoint, what are your thoughts about propane or ethanol as fuel alternatives over gasoline? Personally, I think as long as no harm is done to the environment, either source may be viable.

Both have carbon in them. Do you mean biofuels from crops? I don’t have the latest research to hand.
