Natural ocean cycles behind aggravation in Eastern Australia, new research findings – Is it up because of that?
Via P Gosselin
Eastern Australia suffered a lot of rain in February earlier this year, and the media of course blamed it all on man-made climate change.
Now a new study by Holgate et al (2022) titled “The impact of interactive climate regimes on precipitation moisture sources in Eastern Australia“Shows that precipitation in Eastern Australia is directly related to natural patterns of the ocean.
Hat head: EIKE.
The abstract of the paper summarizes that precipitation in eastern Australia is driven by multiple interacting climate regimes and that the El Niño-Southern Oscillation (ENSO) regulates the supply of evaporative moisture for precipitation and regulation. This is regulated by the Indian Ocean dipole (IOD) and the southern annular mode (SAM).

The authors describe how La Niña facilitates localized precipitation while El Niños involve below-average rainfall.
In an article that appeared in academics CONVERSATION hereThe authors note that there are climate fluctuations that play a role in regulating precipitation in eastern Australia, mainly the El Niño-Southern Oscillation (VISO), Southern annual mode (SAM), and the Indian Ocean Dipole (IOD):
“Just as a character’s mood changes, each climate mode has positive, negative, and neutral phases. Each affects Australia’s weather in different ways,” the authors write. “La Niña brings wetter conditions to eastern Australia. The negative phase of the IOD and the positive phase of the SAM can also bring more rain.”
In other words, rain and dry periods depend on what the ocean cycles are doing, not CO2. Understanding the important natural cycles is key.
However, the authors go on to assert that extreme La Niña and El Niño events and the weather system are “expected to worsen due to greenhouse gas emissions,” but that at best is just speculation. guess. Co2 does not drive ocean cycles and modes.
When “expect” never shows up
We reiterate that Atlantic hurricanes are also “expected to be exacerbated by greenhouse gases”, but the opposite has actually happened in the past decades. In addition, the Arctic is expected to be ice-free in the summer. But that hasn’t happened either, and late summer sea ice there has been on a moderate upward trend over the past 15 years.
The oceans are also expected to warm, but Kenneth noted yesterday, that’s not necessarily the case either. New research shows that the bottom half (2 km to the bottom) of the Pacific Ocean has cooled drastically since 1993!
Professor John Schellnhuber, former director of the PIK Potsdam Institute, also “predicted” the Himalayas to lose glaciers by 2030, but that was also clearly exposed as a real joke of climate bluff. .
So when it comes to extreme weather and future projections, it’s really important to separate science from climate fraud.
