They’re just like the Royal Society
A National Geographic newsletter last March featured climate change. The picture to the right, which appeared in the newsletter, is from NIWA’s website. The caption summarises the effect of carbon dioxide on the climate. It says:
Carbon dioxide, the greenhouse gas that’s getting us into trouble, only amounts to about 385 parts per million of the gases in the atmosphere—not a large amount. But that’s a third more CO2 than 150 years ago, enough to have caused, and continue to cause, significant changes in local and global climate. Twelve of the 13 years from 1995 to 2007 have been the warmest since 1850, while 1998 and 2005 are the warmest years since records began. Over the last 100 years, New Zealand’s temperature has increased by 0.9ºC.
