What is the primary cause of global warming?

Answer 1

The primary cause of global warming is the burning of fossil fuels (coal, oil and natural gas) in industry, transport and to generate electricity. All these processes release extra carbon dioxide which has been hidden away for millions of years. This extra CO2 is disrupting the natural carbon cycle which has kept the planet at a comfortable temperature for as long as life has existed. This extra CO2 is causing the enhanced, or accelerated greenhouse effect in the atmosphere.

Answer 2

The sun provides the original heat.

A:The main factor in global warming is carbon dioxide emissions into the atmosphere from the burning of fossil fuels (coal, oil and natural gas) in industry, transport, and the generation of electricity.

Carbon dioxide (CO2) is a greenhouse gas which traps the sun's heat as it rises from the surface of the earth.

Burning fossil fuels releases carbon that has been hidden away for millions of years. This is why the levels are building up in the atmosphere and causing global warming.

Global warming is then causing climate change.

A:Solar variation is the undisputed start of each of our five warming phases that we know of. This is the current belief of every science group including the IPCC.

CO2 is believed by some groups to be aiding this warming cycle. Man contributes to some of the presence of this gas in our atmosphere. The rise of CO2 has been proven to always follow temperature by some 800 years and never led the temp rise. It is probable that this gas is adding to this warming.

The current start of this warming cycle began roughly 10,200 years ago. Miltun Milankovich tied the four previous warming trends to solar variation and orbital variations of our planet in relation to the sun. This is undisputedly the primary reason for the beginning of the current global warming phase.

A:Man is currently dumping billions of tons of CO2 into our atmosphere. Many believe that this is contributing to the overall warming effect. This CO2 is generated by the creation of energy, heat and cooling of our homes. A:Two factors lead to Global Warming:

1. Fossil Fuels: Man discovered and started to burn fossil fuels (coal, oil and natural gas) at the start of the Industrial Age. This released extra carbon dioxide (CO2) which had been safely buried underground for millions of years. This extra greenhouse gas overwhelmed the natural carbon cycle which is unable to move it all out of the atmosphere. Extra greenhouse gas means an enhanced greenhouse effect, leading to global warming which is driving climate change.
2. Deforestation: At the same time man destroyed many of the great forests of the world. Trees take in CO2, release the oxygen and store the carbon. Half the weight of a tree is carbon. So the missing trees couldn't help remove the extra CO2.

A:Mankind's immense release, on a moment by moment basis, by every population center on Earth, of CO2; and by every report more and more hydrocarbons, Worldwide, are being prepared to be made available for even more! combustion on the moment by moment basis. Please see Carbon Reclamation.

Answer 3

The consensus of climate scientists is that global warming is happening largely because of the increased atmospheric concentration of a greenhouse gas, carbon dioxide. This has increased by more than 35 per cent, from the long-term average of around 260-280 parts per million (ppm) to the present level of over 380 ppm, as a result of human activities such as burning coal, oil and natural gas, as well as deforestation and cement maunufacture.

Answer 4

The main human cause of our CO2 emission is the powering and running of our buildings. Heating and power them creates over 50% of all of our greenhouse emissions.
