Proponents of drastic greenhouse gas controls claim that human greenhouse gas emissions cause global warming, which then exacerbates the frequency and intensity of extreme weather events, including extreme heat, droughts, floods, and storms such as hurricanes and cyclones.
In fact, even though reporting of such events is more complete than in the past, morbidity and mortality attributed to them has declined globally by 93%–98% since the 1920s

Wet and stormy weather lashed California coast… 8,200 years ago
First high resolution evidence of California climate response to Holocene 8.2 ka event
The weather report for California 8,200 years ago was exceptionally wet and stormy.
That is the conclusion of a paleoclimate study that analyzed stalagmite records from White Moon Cave in the Santa Cruz Mountains published online Jun. 20 in Scientific Reports.
The Golden State’s 150-year stretch of unusually wet weather appears to have been marked by particularly intense winter storms and coincides with a climate anomaly in Greenland ice cores first detected in 1997. Before this “8.2 ka event” was discovered scientists thought the world’s climate had been unusually stable during the Holocene, the geological epoch that covers the last 11,700 years of Earth’s history.

Global Warming More Moderate Than Worst-Case Models
A new study based on 1,000 years of temperature records suggests global warming is not progressing as fast as it would under the most severe emissions scenarios outlined by the Intergovernmental Panel on Climate Change (IPCC).

As the reconstruction of the climate’s development in the past by proxy data shows, there’s a series of temperature cycles that appear to be unknown, or ignored by many climate scientists. Among these are the larger climate cycles of 150 million to 180 million years (see Part 1 and Part 2), but also the shorter and for us the more important following cycles:
1000 years (900-1100) Suess cycle with +/- 0.65°C
230 years (230-250) deVries cycle with +/- 0.30°C
65 years (60-65) Ocean cycles with +/- 0.25°C

Studies of bones from Ice Age megafaunal animals across Eurasia and the Americas have revealed that major increases in environmental moisture occurred just before many species suddenly became extinct around 11-15,000 years ago. The persistent moisture resulting from melting permafrost and glaciers caused widespread glacial-age grasslands to be rapidly replaced by peatlands and bogs, fragmenting populations of large herbivore grazers.
The idea of moisture-driven extinctions is really exciting because it can also explain why Africa is so different, with a much lower rate of megafaunal extinctions and many species surviving to this day, says Professor Cooper.

Now let’s extend the time scale and look back 100 years. What a surprise: In the 1930s and 1940s there were two heat decades in the Arctic which were almost as warm as today (Fig. 2). This is just a small fact that went missing in the WMO press release and in the derwesten.de article.

As for the potential cause behind the downward trend, Rojo-Garibaldi et al. examined the possibility of a solar influence, performing a series of additional statistical analyses (spectral, wavelet and coherence wavelet transform) on the hurricane database, as well as a sunspot database obtained from the Solar Influences Data Analysis Center of the Solar Physics Department of the Royal Observatory of Belgium. Therein, their exploratory analyses revealed that “this decline is related to an increase in sunspot activity.”

L’étude concerne l’histoire du climat dans le bassin méditerranéen septentrional (Italie, France, Espagne) entre les XVIe et XIXe siècles. Préalablement, elle présente un état de l’art dans les domaines historiographique, documentaire et méthodologique pour les pays de l’Europe méditerranéenne. Puis, ce travail aborde la question des fluctuations en proposant successivement des reconstructions instrumentales et phénologiques (blé, olives et vendanges).
Selon E. Granier, l’espérance de vie moyenne d’un événement anormal dans la mémoire des gens est de l’ordre de 2 à 5 ans.
