On this day in 1988 the World Meteorological Organisation, (the clue is in the name) sent out invites to be part of what is now known as the IPCC
“In the absence of an official US initiative, WMO took the lead and held discussions with UNEP on this proposal. Eventually, a slightly modified version was sent out by the Secretary General of WMO on March 25, 1988 to member governments inquiring whether their country would like to be represented on a proposed ‘Intergovernmental Panel on Climate Change’ (Obasi, 1988).”

The context is this
The discovery of the ozone “hole” gave atmospheric scientists a high profile and trust. Atmospheric scientists had finally decided at a meeting hosted by WMO, UNEP and ICSCU,, in Villach, Austria, in October 1985, that the carbon dioxide problem they had been studying and talking about in-depth for roughly 15 years, needed proper policy responses
The right-wing administration of the US “President” Ronald Reagan was split, but mostly opposed to this. They DEFINITELY did not want independent scientists pushing them around. So, we get an intergovernmental panel rather than an international one. They key sources – but by no means the only ones – for this, are

What happened next
The IPCC first met in November 1988, in Geneva. Within a year and a half its first assessment report was ready. It was, of course, attacked and enormous attempts were made to water it down. Things really got heated (ho ho) when the second assessment report came out. That was very very nasty indeed…
Meanwhile, the carbon dioxide accumulates
