Hi, I always enjoy your blog.  Would it be possible to toss in a "long term average graph"(the twenty year one) for the 3.4 area into an upcoming blog?  Maybe you've done one recently and I missed it.  Maybe even relate or juxtapose it to Global ocean average if you have that too, since you mention it :) . I'm just itching to see what that twenty year average looks like going as far back as your data goes.  

Thanks
