5:34p	America Honors Its Atomic Veterans America detonated the world's first nuclear device in Alamogordo, New Mexico on July 16, 1945. On its 76th anniversary, U.S. president Biden issued a proclamation: Many brave men and women have risked their lives in service to our Nation, but few know the story of our "Atomic Veterans" — American military service members who participated in nuclear tests between 1945 and 1962, served with United States military forces in or around Hiroshima and Nagasaki through mid-1946, or were held as prisoners of war in or near Hiroshima or Nagasaki. These veterans served at testing sites like the Bikini Atoll and witnessed the destructive power of nuclear weapons firsthand. On National Atomic Veterans Day, we recognize and honor the contributions of America's Atomic Veterans for their sacrifice and dedication to our Nation's security, and recommit to supporting our Atomic Veterans and educating ourselves on the role these patriots played in our national story. Atomic Veterans served our Nation with distinction, but their service came at a great cost. Many developed health conditions due to radiation exposure, yet because they were not able to discuss the nature of their service, they were unable to seek medical care or disability compensation from the Department of Veterans Affairs for their illnesses. Decades later in 1996, the United States Congress repealed the Nuclear Radiation and Secrecy Agreements Act, allowing Atomic Veterans to tell their stories and file for benefits. By then, thousands of Atomic Veterans had died without their families knowing the true extent of their service. Our Nation has one truly sacred obligation: to properly prepare and equip our troops when we send them into harm's way, and to care for them and their families when they return from service. As Commander in Chief, I am committed to fulfilling our obligation to the Atomic Veterans and their families, and ensuring that all of our Nation's veterans have timely access to needed services, medical care, and benefits. On this National Atomic Veterans Day, our country remembers the service and sacrifices of Atomic Veterans. Their heroism and patriotism will never be forgotten and we always honor their bravery and devotion to duty. July 16, 2021 was named "National Atomic Veterans Day." The proclamation ended with a call on all Americans "to observe this day with appropriate ceremonies and activities that honor our Nation's Atomic Veterans whose brave service and sacrifice played an important role in the defense of our Nation."

8:47p	7 Years Later, Google Engineers Revise Their Pessimistic Predictions on Climate Change Seven years ago two Google engineers concluded, after four years of study that "Renewable energy technologies simply won't work; we need a fundamentally different approach." (The authors proposed a R&D portfolio pursuing "disruptive" solutions in hydro, wind, solar photovoltaics, and nuclear power, with one Slashdot reader asking "is nuclear going to be acknowledged as the future of energy production?") But the two engineers — still at Google — recently announced "we're happy to say that we got a few things wrong. In particular, renewable energy systems have come down in price faster than we expected, and adoption has surged beyond the predictions we cited in 2014." One of them told IEEE Spectrum "It's stunning how rapidly things have been moving since the first article was published," Experts now have a better understanding of how a variety of technologies could be combined to prevent catastrophic climate change, the coauthors say. Many renewable-energy systems, for example, are already mature and just need to be scaled up. Some innovations need significant development, including new processes to produce steel and concrete, and geoengineering techniques to sequester carbon and temporarily reduce solar radiation. The one commonality among all these promising technologies, they conclude, is that engineers can make a difference on a planetary scale... Concerned about the pessimistic tone of most climate coverage, the authors argue that wise policies, market pressure, and human creativity can get the job done. "When you put the right incentives in place, you capture the ingenuity of the masses," says Fork. "All of us are smarter than any of us." The Google engineers acknowledge we've already seen a plunge in battery prices to lows not predicted until 2050. (Along with cheap natural gas prices, this cut America's coal consumption in half, lowering emissions.) And fossil fuel consumption has been reduced thanks to cheaper electric heat pumps and electric cars. Other suggestions from their article include: Cleaner air travel (including clean hydrogen-powered planes) New forms of nuclear power Climate policy (including carbon pricing strategies like carbon taxes) "So, engineers, let's get to work."
