Global Warming
There is compelling scientific evidence that the Earth’s temperature is rising, and that this is caused by human activity. This temperature rise is known as ‘Global Warming’. Global warming is caused by ‘greenhouse gases’ in the Earth’s atmosphere. They are named greenhouse gases because they trap heat in the same way that a glass greenhouse traps heat.
When fossil fuels are burnt, a gas called Carbon Dioxide (or CO2) is created. CO2 cannot be seen and doesn’t smell, but it is a huge threat to the Earth. CO2 is one of the main greenhouse gases contributing to global warming. We need to reduce the amount of CO2 that we produce, and look at alternative energy sources that do not produce CO2.
Scientists predict that even if we were to cease all CO2 output today,
global warming would continue beyond the year 2100. Global warming is
a huge danger to the world because of the potential impact it may have
on our climate.
