The Focus forum is now closed.
We're sad to make this announcement because, over the years, the forum has provided fascinating debate on science and technology, and we’ve often printed the discussions in the magazine.
We’d like to thank everyone who’s joined in and made it such interesting reading for fellow forum members and all of us who work on the magazine.

It would be tempting to think the same goes on on both sides though right?
9) Was MBH98 the final word on the climate of last millennium?
Not at all. There has been significant progress on many aspects of climate reconstructions since MBH98. Firstly, there are more and better quality proxy data available. There are new methodologies such as described in Rutherford et al (2005) or Moberg et al (2005) that address recognised problems with incomplete data series and the challenge of incorporating lower resolution data into the mix. Progress is likely to continue on all these fronts. As of now, all of the ‘Hockey Team’ reconstructions (shown left) agree that the late 20th century is anomalous in the context of last millennium, and possibly the last two millennia.
