How travel contributes to the climate change
All means of transportation require energy, which usually comes from burning fossil fuels. Motors running on fossil fuels emit greenhouse gases. Exhaust gases – for example from cars, planes and buses – contribute to climate change. Climate Change is caused by the enhanced greenhouse effect: the warming of the earth due to greenhouse gases in the atmosphere.
Did you know that the greenhouse effect is in essence a natural process?
Greenhouse gases trap heat in the atmosphere, and life on earth would be impossible without that warmth. However, due to deforestation and our use of fossil fuels, the level of greenhouse gases in the atmosphere is now too high. The extra greenhouse gases cause too much heat to be trapped, which has a negative effect on our climate. This is what we mean when we talk about the climate problem. Among the effects that can be seen already, and which will be more evident in the future, are:
• The polar ice caps melting due to increasing temperatures, which in turn means higher sea levels and, eventually, flooding.
• Severe weather conditions such as hurricanes, snowstorms and tornados become more common, and monsoons become heavier.
• Health risks for people, due for example to unexpected heat waves, contagious diseases and less available drinking water.
• Natural ecosystems such as coral reefs, glaciers and mangroves and the associated biodiversity being damaged, and in some cases even lost.
