Climate Change

The United Nations body, which coordinates the work of over two thousand atmospheric scientists, is called the Intergovernmental Panel on Climate Change.  The graphs below illustrate the temperature effects of climate change and the correlation with the principal greenhouse gases.

The major emitters of greenhouse gases are large industrial plants – coal-fired power stations, steel plants, oil refineries, etc.  These are mainly located in the northern hemisphere and in industrialised countries.

The temperature rises are not even across the world.  The largest temperature increases are in the northern hemisphere.
The burning of forests to clear land for agriculture is also a major source of emissions, for example in Brasil.

The Intergovernmental Panel on Climate Change was awarded of the Nobel Peace Prize "for their efforts to build up and disseminate greater knowledge about man-made climate change, and to lay the foundations for the measures that are needed to counteract such change"
