When I was at school the textbooks looking at the amount of gases in the atmosphere told us that 78.9 per cent was not written, 20.95 per cent was oxygen, about 1 per cent was argon and about 0.3 per cent was carbon dioxide. In 2014 carbon dioxide it 400 parts per million, the first time in 2.5 million years and it continues to rise. We now have average global temperatures 1 degree Celsius over the average and set for another 0.5 per cent coming towards us. The hottest years on record have been 2016, 2015, 2014, 2013 and 2010.
