It’s rather obvious from the above that CO2 emissions are no longer rising in sync with economic growth, ie, they have decoupled (for the most part).
Per the above chart, CO2 emissions have declined since 2000 in most of the high-income developed countries but are still climbing in several middle-income nations.
The Emissions Database for Global Atmospheric Research (EDGAR) is a joint project of the European Commission Joint Research Centre and the Netherlands Environmental Assessment Agency which estimates emissions of all greenhouse gases (GHGs), air pollutants and aerosols. The latest EDGAR report is a treasure trove of greenhouse gas emissions data…
This series of posts will focus on countries with the highest CO2 emissions: China, the U.S., India, Russia, Japan, Iran, Indonesia, Saudi Arabia, Germany, Canada, and South Korea. First, the percent of total global CO2 emissions for each country
Why does this matter? Because longitudinal studies have found that students who performed worse in PISA at age 15 are less likely to attain higher levels of education by the age of 25, and are more likely to be out of the labor market entirely, ie, not in education, employment or training. For many, a lifetime of economic hardship and reliance on public services follows.
Part of this performance gap can be explained by socio-economic and language factors, e.g., poverty and lack of fluency in the language used on the tests. I imagine age at immigration matters as well: a person who immigrates as a teenager will likely find school harder in their new country than someone who arrived as a baby. Following this logic, I’d expect second-generation immigrants - born in a country to at least one foreign-born parent - would have little difficulty adapting to a country’s education system and so their PISA scores would reflect this.
Immigrant students often do worse on PISA assessments than non-immigrant students, especially in industrialized countries. However, the performance gap between immigrants and non-immigrants varies considerably across countries. For example…
Per the above chart, American 15-year olds have been reading at roughly the same level (on average) as they were 20 years ago. Surprisingly, their reading performance held up rather well during the pandemic years, despite the challenges of extended school closures, remote learning and the high absenteeism.
Facts are nice, but fact-checking is not always relevant or helpful, especially when it misses the point of whatever statements are being corrected.
“Does a person's perception of their place within the general socioeconomic order directly influence their physical and psychological well-being? Let's pretend that researchers find robust evidence that subjective social status does indeed predict various indicators of well-being, e.g., people who rate themselves lower in the pecking order are less healthy or happy than those with higher self-ratings. What can we learn from such evidence? Nothing much by itself. We'd have to dig deeper.” - Singh-Manoux, Adler, and Marmot (2003)
This post was going to compare police response times (RTs) in the ten most dangerous US cities with the RTs of the safest cities (link). Unfortunately, none of the dangerous cities had decent RT data, except for Oakland, California. But we’re in luck! Oakland has great data, not only for RTs but also for police staffing levels, both across several years.
1. Curiosity …
There is no hard-and-fast threshold for an acceptable clearance rate. That said, Oakland’s rate is abysmal. No wonder Oakland’s the most dangerous city in the US!
These posts will explore factors that are thought to influence violent crime rates, such as police response times, clearance rates, conviction rates, sentencing norms, and demographics. I will limit my exploration to the 10 safest and 10 most dangerous cities listed in the above chart, the better to reveal patterns of influence. Hopefully, these cities keep good records.

For comparison, as of 9/30/24, the Dow Jones average net profit margin was 2.46%; the Nasdaq average net profit margin was 16.09%. And according to a January 2024 analysis by NYU Stern School of Business, the average net profit margin for US corporations across 94 industries was 8.54%, based on a sample of 6481 firms.
Americans used to be fairly united on the need to protect the environment through stricter laws and regulations. That consensus took a nosedive in the 1990s and has never recovered…
The authors don’t tell us why Medicare and insurers are increasingly relying on prior authorization, nor do they address the prevalence of unnecessary or low-value medical care or the risks associated with such care. That’s a huge omission. Potential harms should be weighed against potential benefits, the better to find solutions that preserve benefits while reducing harm. As for the prevalence and risk of unnecessary and low-value care, evidence suggests that up to one-fifth of healthcare spending is wasted on such care and around 10% of patients are harmed in the process.
Around a quarter of healthcare spending in the US is wasted, much of it on unnecessary or low-value tests and procedures that do not improve patient outcomes. Here are a few ways countries and healthcare systems are tackling the problem…
“False consciousness [is] the notion that people are so misled about reality that they act against their own interests. What was once the preserve of Marxists, flummoxed that workers refused to lose their capitalist chains, is now the fall-back position for the modern [left], which worries that voters cannot accurately comprehend the world in which they live.” - Are voters as clueless as Labour’s intelligentsia thinks? The Economist, November 30, 2024.
