What is the *+*+*+ (Global Warming) +*+*+*

The definition of global warming is that there is an increase in the average temperature of our planet due to the increase in the volume of carbon dioxide and methane and other greenhouse gases, since the Industrial Revolution 200 years ago. Many scientists proved that global warming is a very serious issue, because there is a limit for the capacity of ozone in the world.The main problem is that UV rays pass through one hole in the ozone in to the atmosphere and the increase in global temperature will cause the polar Icecaps to melt.This means that the sea level will rise more and more and eventually low lying -areas will be flooded.Big business have argued that there has always been changes in temperature but some are concerned at the rate of these changes.
