Rainfall, Cyclone Data Show No Clear Upward Trend, Contradict IPCC Claims

by P. Gosselin, Mar 19, 2023, in NoTricksZone


Feel helpless when trying to assess the veracity of “climate doom is looming” claims? Don’t give up trying to understand the relevant basics because you don’t need to be a scientist to do so.

There is a rather simple way to get an idea about what this is all about. Even without a scientific background, most people have at least a good common sense. And that’s all it takes to get a grasp of how energy flows back and forth between earth’s surface and the skies.

Today in Part 5, we look at the linkage between the allegedly CO2-driven rise of air and sea surface temperatures on the one side and the disconnect between these increases and their strangely weak to insignificant impact on rainfall and hurricane intensity”.

Preceding chapters see Part 1 1), Part 2 2), Part 3 3), Part 4 4).

Variability of cloud effects vs “greenhouse gas” effects

In the last chapter, we have seen that there are some discrepancies between the global warming trend as claimed by the official climate science and the local evolution of rainfall, which should be a direct consequence of higher temperatures since this causes more evaporation. This seems not to be the case e.g. for Germany, see Fig. 1:

Scientists Find No Human Impact On Extreme Rainfall Events In Southeastern Australia…Rather ENSO Related

by P. Gosselin, May 21, 2019 in NoTricksZone


A new study appearing in the Journal of Weather and Climate Extremes titled “Historical extreme rainfall events in southeastern Australia” – led by LindenAshcroft, School of Earth Sciences, University of Melbourne – shows that even more extreme weather in terms of rainfall existed before 1900 in Melbourne, Sydney and Adelaide.

Moreover, the authors found a “moderate and relatively stable relationship between El Niño–Southern Oscillation (ENSO) and annual variations of total rainfall and the number of raindays.”

Mystery solved : Rain means satellite and surface temps are different. Climate models didn’t predict this…

by JoNova, March 18, 2018


A funny thing happens when you line up satellite and surface temperatures over Australia. A lot of the time they are very close, but some years the surface records from the Australian Bureau of Meteorology (BOM) are cooler by a full half a degree than the UAH satellite readings. Before anyone yells “adjustments”, this appears to be a real difference of instruments, but solving this mystery turns up a rather major flaw in climate models (…)

England & Wales Precipitation Series For 2017

by Paul Homewood, January 8, 2018 in NotaLotofPeopleKnowThat


The England & Wales Precipitation Series has now been updated for last year.

Precipitation totalled 952mm during the year, slightly above the series average of 918mm. In ascending order, 2017 ranked 158th.

There seems to be little evidence of any real trends. Whatever trend can be winkled out of the numbers will likely be too small to notice, and swamped by the natural variability in the data.

The wettest years remain 1872 and 1768. The driest were 1788 and 1921.
