Studies Link Marijuana Legalization to All Sorts of Positive Public Health Outcomes
“Legalization linked to fewer suicides, traffic fatalities, and opioid deaths. A new paper on the public health effects of legalizing marijuana finds “little credible evidence to suggest that [medical marijuana] legalization promotes marijuana use among teenagers” and “convincing evidence that young adults consume less alcohol when medical marijuana is legalized.””
Is the ‘Climate Time-Bomb’ Really Ticking Toward Imminent Catastrophe?
“What is the supposed looming climate catastrophe? Exceeding the threshold in which global average temperature rises 1.5 degrees Celsius above the 1850-1900 baseline. That threshold was established in the 2015 Paris Climate Change Agreement, which aims to hold “the increase in the global average temperature to well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C above pre-industrial levels.” In order to have a 50/50 chance of achieving that goal, the new report calculates humanity must cut its greenhouse gas emissions (chiefly carbon dioxide) basically in half by 2030. Secretary-General Guterres asserted that the report shows that “the 1.5-degree limit is achievable.”
Will humanity inevitably suffer a catastrophic fall if we go over the supposed 1.5 degrees Celsius climatic cliff in 2030? No”
…
“It is the case that the world’s average temperature is about 1.1 degrees Celsius higher than it was between 1850 and 1900. The bulk of that temperature increase largely stems from burning fossil fuels that have loaded up the atmosphere with extra heat-trapping carbon dioxide. Atmospheric carbon dioxide stood at about 285 parts per million around 1850, rising to about 316 ppm by 1958 and is now at 420 ppm.
The report states that the evidence has “strengthened” that man-made global warming is responsible for observed changes in extremes such as heat waves, heavy precipitation, droughts, and tropical cyclones. Recent studies do show that the intensity, frequency, and duration of heat waves have increased since the 1950s and that the frequency of heavy rainfall events has also risen. On the other hand, clear evidence for changes in global trends in meteorological drought is lacking and global tropical cyclone accumulated energy (a measure of the combined duration and strength of tropical cyclones) is not increasing.”
…
“the report does not put a dollar figure on the losses that are projected to result from unmitigated climate change. Perhaps, as the report asserts, that is because “cost-benefit analysis remains limited in its ability to represent all avoided damages from climate change (high confidence).” Still, the report does note, “Even without accounting for all the benefits of avoiding potential damages the global economic and social benefit of limiting global warming to 2°C exceeds the cost of mitigation in most of the assessed literature (medium confidence).” A discreet footnote observes, “The evidence is too limited to make a similar robust conclusion for limiting warming to 1.5°C.” So the costs of trying to keep temperatures from increasing by 1.5 degrees Celsius might be greater than the benefits?”
Virtue Signaling by Scientific Journals Backfires, New Study Finds
UN climate report shows world is flying blind into the storm
“Extreme weather events of the past few years — including the 2022 heat wave that sent temperature records tumbling across much of Europe, and the floods that devastated Pakistan last year — have surprised some of the world’s top climate scientists with just how far they sat outside the normal range.
Experts still know relatively little about when and where these types of extreme climate events will happen. Or what happens when two events, like a drought and a heat wave, hit one place simultaneously. That’s because scientists have tended to look at broader averages across regions, rather than the most intense extremes in specific locations.
“We haven’t asked the models [to] come up with an outrageously high temperature number, like 50 degrees in Canada” — a mark reached during a heat wave in 2021 — “and work out how likely that is or if that’s possible,” said Friederike Otto, an author of the IPCC report and senior lecturer at Imperial College London. “And I think that’s why these are surprises.””
Leading climate scientists send the grimmest of warnings
“he U.N. Intergovernmental Panel on Climate Change, an international body made up of the world’s leading climate scientists. Its latest report on the science and consequences of global warming was seven years in the making, writes POLITICO’s E&E News reporter Chelsea Harvey.
“The report clearly notes that the effects of climate change grow worse and worse with every little incremental bit of additional warming,” Chelsea told Power Switch. “So it’s imperative to reduce emissions as swiftly as possible in order to limit even worse outcomes in the future as much as we can.”
The assessment sends a warning that the effects of climate change are already happening. And humanity is not on track to curb carbon pollution from fossil fuel production, agriculture and other sources enough to halt warming at 1.5 degrees Celsius, the most ambitious international target.
In fact, at the rate the world is burning carbon, the 1.5 C threshold will likely arrive in the next decade.
The world has already warmed 1 degree since the preindustrial era. Wildfires, floods, droughts and hurricanes are growing more severe. Sea levels are swelling as coastal communities and island nations face existential threats from encroaching waters.
Intensifying droughts and agricultural disruptions are creating food and water insecurity. Infectious diseases are surging. And people around the world are increasingly being displaced by climate-fueled disasters.
Human mortality rates from climate disasters were 15 times higher in highly vulnerable regions of the world, compared with more developed places, the report found.”

Why Most Gun Laws Aren’t Backed Up By Evidence
“The Dickey Amendment, first attached to the 1996 omnibus spending bill, for example, famously prevented the Centers for Disease Control and Prevention from funding gun violence studies for decades. A new interpretation of that amendment in 2018 changed that, but Dickey wasn’t the only thing making it hard to study gun violence.
Instead, the researchers told me, the biggest impediment to demonstrating whether gun control policies work is the way politicians have intentionally blocked access to the data that would be necessary to do that research.”
Masks Make ‘Little or No Difference’ on COVID-19, Flu Rates: New Study
“The wearing of masks to prevent the spread of COVID-19 and other respiratory illnesses had almost no effect at the societal level, according to a rigorous new review of the available research.
“Interestingly, 12 trials in the review, ten in the community and two among healthcare workers, found that wearing masks in the community probably makes little or no difference to influenza-like or COVID-19-like illness transmission,” writes Tom Jefferson, a British epidemiologist and co-author of the Cochrane Library’s new report on masking trials. “Equally, the review found that masks had no effect on laboratory-confirmed influenza or SARS-CoV-2 outcomes. Five other trials showed no difference between one type of mask over another.”
That finding is significant, given how comprehensive Cochrane’s review was. The randomized control trials had hundreds of thousands of participants, and made useful comparisons: people who received masks—and, according to self-reporting, actually wore them—versus people who did not. Other studies that have tried to uncover the efficacy of mask requirements have tended to compare one municipality with another, without taking into account relevant differences between the groups. This was true of an infamous study of masking in Arizona schools conducted at the county level; the findings were cited by the Centers for Disease Control and Prevention (CDC) as reason to keep mask mandates in place.”

“While individual mask wearers might get some benefit for a while if they consistently, perfectly wear masks, this does not comport with the aggregate experience.”
