The term, however, is often used to describe the current climate changes due to greenhouse gas emissions. Global warming and climate change are often used interchangeably, although in reality the situation is more complex than just a warming of the planet. This keeps the Earth much warmer than it would otherwise be.
Climate change is caused by the emission by humans of extra greenhouse gasses into the atmosphere.
This makes the greenhouse effect more pronounced, in effect heating the planet more and more. This could cause 94 million people to be flooded each year. By 2100 up to a third of natural habitats may be lost due to climate change. Secure availability of food will be a regional rather than a global problem, but it will be less developed countries who suffer. Although climate change is a global and large scale problem, there are plenty of changes you can make to your everyday life to help reduce the amount of greenhouse gasses being pumped into the world's atmosphere.
