Is The Dry Getting Drier?

by W. Eschenbach, Jul 16 , 2023 in WUWT


So I was wandering through the marvelous KNMI website, and I came across data for the Palmer Self-Correcting Drought Severity Index. This is an index that measures the drought conditions in some given area. The source website says:

The scPDSI (self-correcting Palmer Drought Severity Index) is a variant on the original PDSI of Palmer (1965), with the aim to make results from different climate regimes more comparable. As with the PDSI, the scPDSI is calculated from time series of precipitation and temperature, together with fixed parameters related to the soil/surface characteristics at each location.

Now, the KNMI site only offers linear trends of data. But if you look at the bottom of the KNMI page linked above, or other pages at that level of inquiry, you’ll find that there is an option to download the NetCDF version of the data. As in this case, this NetCDF data is often gridded.

And using that NetCDF gridded file lets me make a graphic showing the average scPDSI for the globe.

Despite Alarmist Reports, Drought In The Horn Of Africa Not From Climate Change

by L. Lueken, Dec 13, 2022 in ClimateChangeDispatch


A recent article in Inside Climate News by writer Georgina Gustin leverages a tragic period of severe drought in the Horn of Africa in order to push an alarmist narrative on climate change.

Gustin claims that food security is threatened by climate change and that millions will starve as a result of it. This is false.

Data show that food security has improved over the past decades of warming. [emphasis, links added]

If there is to be a global food crisis, it won’t be climate change that causes it, but rather the heavy-handed and ultimately futile efforts at controlling the weather by regulating how people grow crops and livestock.

The piece, titled “Climate Change is Driving Millions to the Precipice of a ‘Raging Food Catastrophe’,” focuses primarily on the specific example of the severe ongoing drought in Kenya and neighboring Somalia and Ethiopia.

The Great Famine of the 21st Century

by D. Siegel,  Nov 29, 202 in Shortfall


The true tragedy

The problem isn’t the future. The problem is what we’re doing right now. Today, humans spend more than $1 trillion every year on decarbonization, which will most likely have no measurable effect on our future climate. But it does raise the price of energy, and the current virtue-signaling environment prevents people in the developing world from reaching the standard of living we take for granted.

Today, life expectancy in sub-Saharan Africa is 60 years — the same as it was in the United States in 1935. Today, about 60 percent of sub-Saharan people are farmers the same as in the US in 1860. About 500 million people in Africa live in extreme poverty. According to the World Bank, half the countries in Sub-Saharan Africa have poverty rates higher than 35%.

And yet, that same World Bank won’t lend them money to build a reliable energy grid. The United Nations and the World Economic Forum are forcing Africans to install solar and wind projects that can’t help them cook dinner, so they continue to burn trees, charcoal, and dung, destroying forests and dying of lung diseases. They are — right now — being forced to live lives we lived in 1850.

Yes, you say, but prices of solar panels are coming down! Imagine you have a car that drives really well whenever the sun is shining or the wind is blowing. No batteries, nothing, it just works. It’s not even that expensive, and it is magically zero emission. Now, can you get rid of your regular car? Or do you need to have your own back-up car for whenever the sun isn’t shining or wind isn’t blowing? You might think you could just rent or use an Uber then, but that’s exactly when everyone else needs a car, too, so you actually have to maintain your existing car, pay the insurance, make sure it’s always available, for those times when your renewable car isn’t possible and the Uber is taken. That’s twice as many cars, no matter who owns them. That’s not “sustainability.”

Summary

As you have just learned, we live in the safest century to be alive. We are more protected against natural disasters than ever. And we are being lied to about CO2 and climate.

This isn’t easy for a lot of people to hear. It has become a matter of tribal and political identity. I know. In 1991, I wrote a book about how CO2 was changing the climate. But then I dug deeper and realized not everything was as it seemed. When I started to tell others the science wasn’t settled, I lost quite a few friends. If you have read this far, thank you for being brave. I invite you to take the next step at Climatecurious.com.

Scientists Warn of a Rare Third Year La Nina

by INSTITUTE OF ATMOSPHERIC PHYSICS, CHINESE ACADEMY OF SCIENCES,  Oct 21, 2022 in WUWT


El Niño–Southern Oscillation (ENSO) is an irregular periodic variation in winds and sea surface temperatures over the tropical eastern Pacific Ocean that affects the climate of much of the tropics and subtropics. This natural phenomenon is important to study because of the socioeconomic impacts it can have on matters such as food security, agricultural production, human health and water resources, to name but a few.

With its strong preference to peak during boreal winter and rapidly decay in spring (known as “phase-locking”), and quasi-periodic oscillations of 2–7 years, historically, ENSO rarely maintains for long in either its cold phase (La Niña) or warm phase (El Niño). However, since the turn of the current century, three instances of so-called “double dip” La Niña events have occurred, in 2007–09, 2010–12 and 2020–22.

This succession of double-dip La Niña events is intriguing enough in itself; but now, based on updated data from several organizations issued in April 2022, it seems that the current event is likely to continue through the boreal summer and fall of 2022, suggesting a strong possibility of a third-year La Niña lasting from 202023.

“This would be the first third-year La Niña since the 1998–2001 event, which was the only such event observed since 1980,” explains Dr Xianghui Fang from Fudan University, China.

BBC Exaggerate Drought Claims

by P. Homewood, July 27, 2022 in NotaLotofPeopleKnowThat


To compare this year with 1976 is really quite mendacious, as the latter was much, much drier. And as the BBC’s own chart shows, there have been eight other years since then with similar rainfall levels to this year. Indeed, in England, as opposed to England & Wales, both 1996 and 2010 had drier starts to the year).

In other words, this year is not an exceptional event, merely something you expect to see every few years or so.

And if you go back through the full Met Office record to 1836, we can see again that there is nothing at all unusual about this year.( Indeed, all of the really dry years occurred in 1976 and before:

LONG-TERM US DROUGHT AND PRECIPITATION TRENDS

by R. McKitrick & J. Christy, Sep. 14, 2019 in WUWT


Ross McKitrick and John Christy have published a new paper in the Journal of Hydrology.

Abstract : We estimate trends in US regional precipitation on multiple time spans and scales relevant to the detection of changes in climatic regimes. A large literature has shown that trend estimation in hydrological series may be affected by long-term persistence (LTP) and selection of sample length. We show that 2000-year proxy-based reconstructions of the Palmer Modified Drought Index for the US Southeast (SE) and Pacific Coast (PC) regions exhibit LTP and reveal post- 1900 changes to be within the range of longer-term natural fluctuations. We also use a new data base of daily precipitation records for 20 locations (10 PC and 10 SE) extending back in many cases to the 1870s. Over the 1901–2017 interval upward trends in some measures of average and extreme precipitation appear, but they are not consistently significant and in the full records back to 1872 they largely disappear. They also disappear or reverse in the post-1978 portion of the data set, which is inconsistent with them being responses to enhanced greenhouse gas forcing. We conclude that natural variability is likely the dominant driver of historical changes in precipitation and hence drought dynamics in the US SE and PC.

Drought Proofing a Dry Continent

by Viv Forbes, August 16, 2018 in WUWT


Sensible drought-proofing policies for Australia are simple –

  1. Stop wasting water
  2. Build more dams, pipelines and pumps
  3. Build power stations capable of delivering cheap reliable electricity for pumping water and energising desalination plants.
