In the industrial revolution (a period beginning in the 18th century) when man began to burn fossil fuels. About 250 years ago.
If you were asked to speak in a debate, "Against man-made Global Warming" you would be arguing that man is not causing Global Warming. You would have to argue that Global Warming is occurring naturally.
Global warming was made as a result of continuous activities that depleted the ozone layer. Pollution from burning fossil fuels is one of the main contributors of global warming.
Global warming is true. The world is actually getting warmer, and will continue to do so.
We humans made global warming when we started burning coal, and cutting down forests. The burning of fossil fuels (coal, oil and natural gas) and deforestation (cutting down trees which previously removed carbon dioxide (CO2) from the atmosphere) started the global warming. As the world's population grows, and everyone wants a car, a TV and air conditioning, the greenhouse effect can't cope with all the extra carbon dioxide pollution.
it made the world hotter
global warming or economy
No, it just prevents an increase. Reduction of global warming has to be done through carbon sequestration, natural or man-made.
In nearly everything that we do we are the cause of global warming such as driving a car, turning on a light, or even the smoke from factories.
Primarily Carbon Dioxide and Methane.
tsunami and global warming
Respiration is part of the carbon cycle and does not affect global warming.
ozone layer is affected by the man made and natural causes. Somewhere down the line, it also causes global warming.
