Back in late April, European wine growers were hit by the most damaging frost since 1991. That frost affected vines as far south as Tuscany. More recently it is the western Corn Belt that has been affected by late Spring frost (…)

Right now, the sun is a cueball, as seen below in this image today from the Solar Dynamics Observatory (SDO) and has been without sunspots for 10 days. So far in 2018, 61% of days have been without sunspots (…)
British Antarctic Survey, April 9, 2018
Presenting this week (Monday 9 April 2018) at the European Geosciences Union (EGU) meeting in Vienna, an international team, led by British Antarctic Survey, describes how analysis of 79 ice cores collected from across Antarctica reveals a 10% increase in snowfall over the last 200 years. This is equivalent to 272 giga tonnes of water – double the volume of the Dead Sea.
Lead author and ice core scientist Dr Liz Thomas from British Antarctic Survey explains: (…)

Canada’s stable-to-increasing polar bear population extends its range slightly further south of the 55th parallel (York et al., 2016).
According to published geological evidence from the 1950s, remnants of wine grape vineyards have been unearthed in regions as far north as the polar-bear-inhabiting 55th parallel during the Medieval Warm Period (~800s to 1300s AD).

On Spitzbergen it was as warm 70 years ago as it is today
By Dr. Sebastian Lüning and Prof. Fritz Vahrenholt
(German text translated by P Gosselin)
Newspapers like to write about heat and melt records in the Arctic, which supposedly had never happened before. That really sparks fear among the citizens. However an examination of the facts regularly brings amazing things to light, for example weather records from a German station on Spitzbergen during World War 2 for the period of 1944-1945.
In the journal International Journal of Climatology Rajmund Przybylak and his colleagues evaluated the data. Summary: Back then it was similarly warm as it is today

Little is known about the ice age human occupation of the Pacific Coast of Canada. Here we present the results of a targeted investigation of a late Pleistocene shoreline on Calvert Island, British Columbia. Drawing upon existing geomorphic information that sea level in the area was 2–3 m lower than present between 14,000 and 11,000 years ago, we began a systematic search for archaeological remains dating to this time period beneath intertidal beach sediments (…)

“Le contenu de la mémoire est fonction de la vitesse de l’oubli”
Désormais, chaque inondation quelque peu catastrophique, chaque tornade, chaque anomalie météorologique est rattachée au réchauffement climatique qui parait-il nous menace, mais dont en plus l’homme serait responsable !
Pourtant, la consultation de chroniques ou récits anciens est révélatrice de précédents tout aussi apocalyptiques, et relativise la notion même de “changements climatiques”, ainsi que la définition d’un “climat stable” qui n’a jamais existé mais qu’on voudrait instaurer à tout prix.

Well, folks were complaining that my graph of the CET compared to the centennial solar minima was just one location, England. So here are the five European temperature records which start before 1815. Now, if the theory of the solar/temperature connection is correct, the temperatures should start trending downward when the solar minima start, and they shouldn’t start warming back up until the sunspots get numerous again after the end of the minima. Here are the records so you can see if they agree with the theory.
(…) As you can see, there is no obvious sign that the solar minima have caused any change in the temperature. Some go up, some go down, some go nowhere.(…)

Dr. Sebastian Lüning and Prof. Fritz Vahrenholt today here are asking how sea level rise is doing because as have not heard much about it lately. A good place to start is at Climate4You. Strangely the data go only until December 2016. And if you look at the data from the source form the University of Colorado, we find the same. So what’s with 2017?

Ce travail tente de prouver l’intérêt pour l’assureur d’une approche historique consacrée aux tempêtes et aux cyclones entre 1500 et nos jours. Les exemples de la France, de l’Europe et de l’océan Indien montrent que ces événements extrêmes sont en réalité des facteurs de permanence historique et que les archives peuvent être très utiles pour estimer leur sévérité. Dans cette perspective, une simulation du coût actuel de la tempête atlantique de mars 1937 est réalisée. Elle révèle que les sociétés littorales de cette époque étaient nettement plus résilientes. Enfin, l’étude prouve que, depuis la fin de la Seconde Guerre mondiale, la vulnérabilité a augmenté plus rapidement que l’aléa tempête, notamment depuis les années 1990 avec l’urbanisation croissante des littoraux.
