Sept. 2016: The link to the Azimuth forum is wrong.<br \/>\nThe discussion to the image can currently be found <a href=\"https:\/\/forum.azimuthproject.org\/discussion\/comment\/13594\/#Comment_13594\">here.<\/a><br \/>\nBlue curves are global temperature anomalies in odd years starting in 1711 and red curves are global temperature anomalies in even years (HADCRUT 4) starting in 1712. The black jagged curve is the difference between the two curves (red &#8211; blue); the less jagged black curve is the integral over that jagged black curve. One sees that the temperature in odd years seems to be on average higher, since the less jagged curve is always below the zero line. This might however also partially be due to partially not so well balanced temperature measurements espiacially in the 18th and 19th centuries or related <a href=\"http:\/\/www.randform.org\/blog\/?p=5806\">problems.<\/a><\/p>\n<p>In more detail I wrote in that Azimuth project comment: <\/p>\n<blockquote><p>So as you can see the integral stays clearly below zero (it is actually even scaled by 0.01), but indeed between 1840s or 1860s and 1920s the temperatures seem to flip on average even and odd years at least for that station data and for this case of directly comparing the months in cosecutive years. That is the integral curve ascends. This could thus be correlated with the alledged phase reverse of the <a href=\"http:\/\/en.wikipedia.org\/wiki\/Chandler_wobble\">Chandler wobble<\/a>, however I don&#8217;t see anything in 2005. But this might eventually be due to the rottening of the temp file. No guarantee for correctness I just hacked that in.<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>We here at randform are superexcited to present our first reader randform mega contest &#8211; simply called LeContest !!<\/p>\n","protected":false},"author":3,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[4,25,15,26,2,7,31],"tags":[],"_links":{"self":[{"href":"https:\/\/www.randform.org\/blog\/index.php?rest_route=\/wp\/v2\/posts\/5741"}],"collection":[{"href":"https:\/\/www.randform.org\/blog\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.randform.org\/blog\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.randform.org\/blog\/index.php?rest_route=\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.randform.org\/blog\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=5741"}],"version-history":[{"count":12,"href":"https:\/\/www.randform.org\/blog\/index.php?rest_route=\/wp\/v2\/posts\/5741\/revisions"}],"predecessor-version":[{"id":6273,"href":"https:\/\/www.randform.org\/blog\/index.php?rest_route=\/wp\/v2\/posts\/5741\/revisions\/6273"}],"wp:attachment":[{"href":"https:\/\/www.randform.org\/blog\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=5741"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.randform.org\/blog\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=5741"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.randform.org\/blog\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=5741"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
