Continental United States Hurricane Landfall Frequency and Associated Damage: Observations and Future Risks

by Ph. Klotzbach et al., February 2018 in Amer.Met.Society


.pdf (56 pages)

Continental United States (CONUS) hurricane-related inflation-adjusted damage has increased significantly since 1900. However, since 1900 neither observed CONUS landfalling  hurricane frequency nor intensity show significant trends, including the devastating 2017 season.

Two large-scale climate modes that have been noted in prior research to significantly impact CONUS landfalling hurricane activity are El Niño-Southern Oscillation on interannual timescales and the Atlantic Multi-decadal Oscillation on multi-decadal timescales. La Niña seasons tend to be characterized by more CONUS hurricane landfalls than do El Niño seasons, and positive Atlantic Multi-decadal Oscillation phases tend to have more CONUS hurricane landfalls than do negative phases.

Le climat et son histoire

by Emmanuel Le Roy Ladurie, 2012 in CairnInfo


Beaucoup de gens, à juste titre, sont impressionnés par les prédictions pessimistes du GIEC  relativement à la fin du xxie siècle, et il est fort possible que ces prédictions soient justifiées. La tâche de l’historien, c’est plutôt de resituer l’histoire du climat dans des périodes récentes ou moins récentes et de réfléchir, ensuite, en toute indépendance, en toute objectivité, sur ce qui nous attend, tant en fonction de ce qui s’est passé déjà, qu’en fonction des résultats impressionnants que nous proposent, avec raison sans doute, les sciences exactes.

HISTOIRE DES TEMPÊTES

by E.  Garnier, septembre 2012, in Risques, les Cahiers de l’Assurance


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.

Media Silence: Flurry Of Recent Papers Show Warming Likely Will Lead To LESS STORM ACTIVITY!

by P Gosselin, December 26, 2017 in Lining and Vahrenholt, No TricksZone


What follows are 6 recent studies presented by Lüning and Vahrenholt, which dump cold water on the claim storms will get more frequent and intense.

The studies fly in the face of a recent Nature editorial piece, one filled with the usual worn out alarmist propaganda language of climate doom we’ve been seeing for over a quarter century. The editorial claims some scientists have already found the link between “weird weather” and greenhouse gases.

Study: a ‘statistically significant downward trend since 1950 exists’ in hurricane landfalls

by Anthony Watts, December 9, 2017 in WUWT


This is going to rattle some cages, while at the same time vindicating Dr. Roger Pielke Jr. A new study in Geophysical research Letters studies hurricane activity in the Atlantic concludes that a “statistically significant downward trend since 1950 exists”.

Again And Again: Experts And New Findings Show No Link Between European Storm Activity And CO2

by P. Gosselin, October 31, 2017 in NoTricksZone


By Dr. Sebastian Lüning and Prof. Fritz Vahrenholt
(German text translated/edited by P. Gosselin)

This month two major North Sea storms have hit Europe rather severely, and not surprisingly the usual climate ambulance chasers were out in force to try to pin the blame on man’s activity, and in doing so ignored the climate history that provides us with the proper perspective. We look at some analyses of past German storm activity.

Tropical Cyclone Trends

by Australian Gov. Bureau of Meteorology, September 2017


Tropical cyclones in the Australian region are influenced by a number of factors, and in particular variations in the El Niño – Southern Oscillation. In general, more tropical cyclones cross the coast during La Niña years, and fewer during El Niño years.

Analysis of historical tropical cyclone data has limitations due to a number of changes in observing practices and technology that have occurred over time. With new and improved meteorological satellites our ability to detect tropical cyclones has improved, as has our ability to differentiate tropical cyclones from other tropical weather systems such as monsoon depressions, which in the past may have been incorrectly named as tropical cyclones. A particularly important change occurred in the late 1970s when regular satellite images became first available from geostationary satellites above the Earth’s equator.

Inevitable Disaster: Why Hurricanes Can’t Be Blamed On Global Warming

by Roy W. Spencer, September18, 2017, in GlobalWarming


Partly in response to the crazy claims of the usual global warming experts (Stevie Wonder, Beyoncé, Jennifer Lawrence, Mark Ruffalo, Bill Nye the Science Guy, Neil deGrasse Tyson, Pope Francis), I decided to write another Kindle e-book. This one is entitled, Inevitable Disaster: Why Hurricanes Can’t Be Blamed On Global Warming.

Puerto Rico’s Hurricane History

by P.  Homewood, September 22, 2017 in NotaLotofPeopleKnowThat


As Hurricane Maria heads north as a Cat 3 storm, much is being made of the fact that it is the strongest hurricane to hit Puerto Rico since 1928. The implication is that Maria must have been exceptionally strong.

But the reality is that Puerto Rico is little more than a speck in the vastness of the Atlantic Ocean. The odds of the eye of a major hurricane, often just 10 or 20 miles wide, making a direct hit on Puerto Rico are probably hundreds to one, given that there are thousands of miles of ocean through which hurricanes can commonly travel.
