2016: the first year of 400 ppm? The Foster Lab interviewed on BBC Radio Weather Show

A paper published this week by Richard Betts of the UK Met Office predicted that 2016 will be the first year CO2 will be >400 ppm at the Mauna Loa observatory all year round.  Given the 2-3 ppm yearly increase this signals that CO2 is likely to remain >400 ppm for our lifetime.  This was featured by the BBC website that also included reference to the work fo the Foster Lab and one of our earlier blog posts.  On Wednesday this week Gavin was also interviewed for the Paul Hudson Weather Show about the last time CO2 was 400 ppm.  The show was broadcast this morning at 6am (18/6/16) on BBC Radio Humberside and will be broadcast on BBC Radio Lincolnshire on monday (20/6/16).  You can also listen to the entire show here:


or fast forward to 32 mins to hear Gavin!

The question is now not if we are heading for a Pliocene-like future, but how long will it take to get there...
