Similar to the subsequently corroborated Great Barrington Declaration on Covid (here), a new declaration on climate change was released in June 2022 entitled ‘World Climate Declaration: There Is No Climate Emergency’. This declaration is signed by hundreds of scientists and thousands of technical professionals from almost every country in the world (here).
In asserting that there is no climate emergency, the undersigned state –
Climate science should be less political, while climate policies should be more scientific. Scientists should openly address uncertainties and exaggerations in their predictions of global warming, while politicians should dispassionately count the real costs as well as the imagined benefits of their policy measures.
Natural as well as anthropogenic factors cause warming The geological archive reveals that Earth’s climate has varied as long as the planet has existed, with natural cold and warm phases. The Little Ice Age ended as recently as 1850. Therefore, it is no surprise that we now are experiencing a period of warming.
Warming is far slower than predicted The world has warmed significantly less than predicted by IPCC on the basis of modeled anthropogenic forcing. The gap between the real world and the modeled world tells us that we are far from understanding climate change.
Climate policy relies on inadequate models Climate models have many shortcomings and are not remotely plausible as policy tools. They do not only exaggerate the effect of greenhouse gases, they also ignore the fact that enriching the atmosphere with CO2 is beneficial.
CO2 is plant food, the basis of all life on Earth CO2 is not a pollutant. It is essential to all life on Earth. More CO2 is favorable for nature, greening our planet. Additional CO2 in the air has promoted growth in global plant biomass. It is also profitable for agriculture, increasing the yields of crops worldwide.
Global warming has not increased natural disasters There is no statistical evidence that global warming is intensifying hurricanes, floods, droughts and suchlike natural disasters, or making them more frequent. However, there is ample evidence that CO2
They conclude with –
To believe the outcome of a climate model is to believe what the model makers have put in. This is precisely the problem of today’s climate discussion to which climate models are central. Climate science has degenerated into a discussion based on beliefs, not on sound self-critical science. Should not we free ourselves from the naive belief in immature climate models?
California Exodus Refuted?

A reader and correspondent sent me the following article – ‘A Shocking Number of Californians Are Moving to Texas Unless You Do Basic Math’. Therein the author cites data and analysis from a market data firm Placer.ai which sidesteps the long-running and well-established California exodus phenomenon, focuses on the California-to-Texas migration, and erroneously concludes that there is nothing unexpected about the numbers that Placer has collected. To wit –
The logic here is very simple. Some people move between states every year for normal life reasons. That’s good and normal and not cause for alarm. And California has the most people of any state. Therefore, all things equal, we’d expect lots of people from California to be moving to Texas. In fact, we would expect that more people from California would be moving to Texas than from any other state, again, because California has the most people. This would not in itself imply anything is wrong with California or great about Texas. It would simply mean people are doing what we would expect them to do. The only way this particular data point would suggest something is indeed amiss is if a disproportionate number of new Texans came from California relative to California’s population.
That may sound confusing, but doing some quick math makes it all very clear. The population of the United States minus Texas—because people already in Texas cannot move to Texas—is 300.86 million people. California’s population is 39.35 million, or 13 percent of the U.S.’ non-Texas population. Therefore, more than 13 percent of Texas’ new residents would have to be Californians in order for there to be something of note going on here.
But that’s not the case. According to Placer.ai, which uses “foot traffic data” gleaned by tracking people's phones, 11.1 percent of new Texans from July 2019 and July 2022 are from California. That’s actually slightly less than one would expect based on an even distribution. If anything, the pertinent question from Placer.ai’s data is: Why are so few Californians moving to Texas?
The main flaw in the argument here is that people move randomly between states with ingress and egress rates proportional to source and target populations. This is a gross error in the current situation where most of migrating Americans are motivated by economic (taxes, regulations) and socio-political (crime, education) reasons. For example, Texas receives many new residents from so-called shithole cities in states like New York, Illinois, New Jersey, in addition to California. Such movements can invalidate any arguments based on randomness. For example, California’s lower percentage of “new Texans” can be completely explained away by the greater number of the state’s immigrants arriving from the other escape-worthy states that need have no relationship to population proportions, and greater numbers of Californians moving to other states such as Idaho, Wyoming, and Florida.
Bloomberg reports, “The long-term migration out of California accelerated during the Covid-19 crisis, with Texas, Washington and Florida as top destinations for people moving out of the state, according to a study from the Federal Reserve Bank of Chicago.” (here) The LA Times continues its ongoing reports of the exodus with ‘California Exodus Continues: LA, San Francisco lead the way’.
Liberals across the land are desperate to refute the mass migrations out of the major shithole regions that Democratic administrations have created since the launch of Great Society programs. This gives rise to a number of loudly argued but logically weak pieces that appear in various lamestream outlets. The fundamental reality is that California continues to create conditions that drive out large numbers of its wealth-generating workers and businesses. This is apparent from all types of correctly analyzed data starting with what we learn from the Dept of Commerce (Census Bureau) and going all the way down to California’s historic first-time reduction in the number of representatives we send to Congress.
