If you think Tylenol is bad for children’s health, wait until you see what guns do.
Firearms were responsible for 20 percent of all child and teen deaths in the U.S. for both 2020 and 2021, compared to an average of less than 2 percent in similarly large and wealthy nations, according to a new KFF analysis. This puts the U.S. far ahead of peer nations in child and teen firearm deaths. Data show that U.S. firearm deaths for children and teens again surpassed motor vehicle deaths – the second leading cause of death – and that the increase has been primarily driven by gun assault deaths. On a per capita basis, the firearm mortality rate among children and teens in the U.S. is over 9.5 times the rate of Canada, the country with the second-highest child and teen firearm death rate. If firearm deaths in the U.S. had mirrored Canada’s rates between 2010 and 2021, approximately 30,000 U.S. children and teenagers would still be alive.

When a tyrant directs his enforcers to start arresting judges, it’s not because lawlessness was at the gates, it’s because lawlessness has been enthroned.

Lady Justice herself now stands shackled, her scales discarded, a prisoner of the very tyranny she once protected us against.

Rare O-type star powers NGC 6164, a 4-light-year-wide nebula with striking bipolar symmetry. Just 3–4 million years old, the star will end in a supernova. A faint halo hints at its active past. Also called the Dragon’s Egg, it lies 4,200 light-years away in Norma.

NGC 6302, also known as the Butterfly Nebula, is a remarkable example of how stars, as they age, can take on some nice shapes sometimes resembling flowers or insects.

#Hubble' s image shows the Butterfly Nebula (NGC 6302), a planetary nebula with a symmetrical structure resembling butterfly wings. In the center, a dense ring of dust obscures the central star. The nebula expands in vivid hues: deep blue (oxygen), bright green (hydrogen), and hot red (nitrogen), creating a bright, layered effect against a black background of space. The gaseous "wings" extend widely, with intricate details and glowing filaments.

87 years ago.

In April 1938, Guy Callendar published the first evidence from thermometer observations that the world’s land areas were warming.

He also linked the observed warming to the increase in atmospheric CO₂ from burning coal.

87 years ago.

A statement I must make:

I have written a short statement responding to mass firings today of #NOAA / National Weather Service (#NWS) staff (which were concentrated among recent hires as well as highly experienced staff who had recently been promoted). Please see below screenshot & below for full text.
Statement begins: The mass firing of both new hires and recently promoted senior staff within NOAA, including mission-critical and life-saving roles at the National Weather Service (NWS), is profoundly alarming. It appears that NOAA staff fired today include meteorologists, data and computer scientists responsible for maintaining and upgrading weather predictive models, and technicians responsible for maintaining the nation’s weather instrumentation network (among many others). Housed within NOAA, the U.S. NWS is a truly world-class meteorological predictive service, perhaps singularly so. Its cost of operation is only ~$3-4/yr per taxpayer—equivalent to a single cup of coffee—and yields a truly remarkable return on investment (at least 10 to 1, and perhaps 100 to 1, depending on methods of estimation). NOAA and the NWS collectively offer tens to hundreds of billions of dollars each year in net economic benefit through a combination of averted losses and efficiencies gained....

I am now hearing from multiple folks in the past two hours (including some who have personally been fired) that mass firings have now commenced within NOAA--including, yes, at the National Weather Service.

Following historic wildfire disasters in Southern California, a statewide dry spell intensifies and extreme fire weather conditions persist in the south - Weather West
Remarkable wet-to-dry transition combined with extreme downslope wind event yields dual wildfire catastrophes in SoCal It's never good feeling when a dire weather or disaster risk prognostication comes to fruition; that "pit in your stomach" sensation has been described by many meteorologists, climate scientists, emergency managers, and disaster-focused researchers over the years. It certainly encapsulates

The Tarantula Nebula, also known as 30 Doradus, is more than a thousand light-years in diameter, a giant star forming region within nearby satellite galaxy the Large Magellanic Cloud. About 180 thousand light-years away, it's the largest, most violent star forming region known in the whole Local Group of galaxies. The cosmic arachnid sprawls across this magnificent view, an assembly of image data from large space- and ground-based telescopes. Within the Tarantula (NGC 2070), intense radiation, stellar winds, and supernova shocks from the central young cluster of massive stars cataloged as R136 energize the nebular glow and shape the spidery filaments. Around the Tarantula are other star forming regions with young star clusters, filaments, and blown-out bubble-shaped clouds. In fact, the frame includes the site of the closest supernova in modern times, SN 1987A, at lower right. The rich field of view spans about 2 degrees or 4 full moons in the southern constellation Dorado. But were the Tarantula Nebula closer, say 1,500 light-years distant like the Milky Way's own star forming Orion Nebula, it would take up half the sky.

A reminder for those who still haven’t understood: ChatGPT and other LLMs are designed to write language that matches patterns found in existing texts so the generated text sounds plausible. It absolutely does not query for “facts” in the way that we have come to think of “googling” information.

I write with @juliaangwin.com about our study that showed 50% of AI models’ responses to questions voters might ask were inaccurate.

Government must hold companies accountable, including through the privacy law called for by POTUS in his powerful #SOTU speech.

🚨 Update. Methane also reached a preliminary new record high value in November 2023 (1934.2 ppb).

November 2022's global methane abundance was 1923.6 ppb.

Note there is a seasonal cycle. Data available from gml.noaa.gov/ccgg/trends_...
