Cela fait un an, le 31 juillet 2017, que le Professeur Istvan Marko nous quittait prématurément à l’âge de 61 ans.
Ce scientifique, chimiste, était un de ceux qui était le plus écouté à l’échelle nationale et internationale, pour ses avis pertinents sur les problèmes climatiques d’aujourd’hui, aussi bien sous l’angle scientifique que celui de leurs emballements médiatiques. Nous lui avons rendu hommage il y a un an à travers un numéro spécial dédié à sa personne, et poursuivons son action dans l’esprit qui fut toujours le sien , celui de la rigueur scientifique.
The famous Oxford Dodo died after being shot in the back of the head, according to new research. Using revolutionary forensic scanning technology and world-class expertise, researchers have discovered surprising evidence that the Oxford Dodo was shot in the neck and back of the head with a shotgun.
The significant and unexpected findings, made by Professor Paul Smith, director of the Museum of Natural History, and Professor Mark Williams from WMG at the University of Warwick, only became apparent when mysterious particles were found in the specimen during scans carried out to help analyse its anatomy.
In today’s post I am going to go over how I went about creating a reconstruction of the history of temperature from the GHCN data sets using a variable number of stations reporting each year for the years of 1900 to 2011. Before I go into the details of that reconstruction, let me cover how I went about discarding some alternative methods.
I decided to create a test case for reconstruction methods by picking five random, complete station records. I then deleted a portion of one of those records. I mimicked actual record conditions within the GHCN data so my testing would be realistic. In different trials I deleted all but the last 20 years, all but the first 20 years or some number of years in the middle. I tried normalizing each station to its own average and averaging the anomalies. I tried averaging the four complete stations, then normalizing the fourth station by its average distance from the main average. In all cases when I plotted the reconstruction against the true average the errors were quite large.normalizing the fourth station by its average distance from the main average.

LONDON (Reuters) – Emissions regulated under Europe’s carbon market rose for the first time in seven years in 2017 due to stronger industrial output, data published on Tuesday by the European Commission and examined by carbon analysts at Thomson Reuters showed (…)
CLAIM: “There isn’t any warming. All they’ve got is computer model predictions, folks. There isn’t yet any empirical evidence for their claim that greenhouse gases even cause temperatures to increase. There isn’t any empirical data for that.”
Winter, apparently, does not want to step back and let spring in as May snow has once again covered the Russian capital ahead of the annual V-Day parade. Meteorologists say May 2017 is on track to break the precipitation record from 1922.
“Storms of such power in Moscow take place once in 30-35 years,” Evgency Tishkovets from the Fobos weather monitoring centre told local Govorit Moskva radio, adding that it is possible that this May can break an absolute record from 1922.
Extraordinary images are now coming from the Newfoundland and Labrador town, where the snow is high enough to cover doors and windows completely. More than 135 cm of snow has fallen on the town of Gander, Nfld., over the past week after it was hit with two back-to-back Nor’easters.
To put that precipitation in perspective, Torontonians can expect around 115 cm of snow in an entire year.
