Why does our climate change?
According to international scientific studies climate change is a steadily global warming over the last decades.
The  Intergovernmental Panel on Climate Change (IPCC) predicts a rise of the global average
temperature between 1,1°C and 6,4°C until 2100.
According to the current scientific knowledge, climate change is caused by an increase of greenhouse gases in the
atmosphere. The main greenhouse gases are carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) accounting for
74% of the overall global warming effect. These gases reach the atmosphere as a result of activities of the everyday
life: the use of energy from fossil fuels (coal, oil, gas) in industrial processes, when flying or driving or when
using electric equipment. But greenhouse gases also come from agricultural production and deforestation.
Due to the increased concentration of greenhouse gases in the atmosphere a stronger greenhouse gas effect results in
steadily rising temperatures - global warming.

United Nationes activities and knowledge on climate change.
