This recommendation was reportedly prompted by a renewed rise in demand from miners—something that brings back bad memories for PC gamers—and insufficient production capacity from TSMC. … [Read more...] about Report: Nvidia has ended production of its top Turing RTX cards

For example, in the limit of weak gravity, Einstein's equations reduce to the more familiar expressions of Newtonian gravity, which is used to explain everything from the trajectories of thrown baseballs to hydroelectric dams. Beyond the surface of the Earth, Einstein takes more control, where the equations of relativity are used to provide accurate positioning with the GPS system and precisely predict the orbits of all the planets. … [Read more...] about What’s the most amazing thing about the universe?
Eventually (ideally sooner rather than later), efforts to reduce greenhouse gas emissions are going to have to be joined by a technology that actively removes CO2 from the atmosphere. There are a number of options—from re-growing forests to burning biofuels in power plants that capture the emitted CO2—and we'll probably need several of them to get us to net zero emissions. Some of these options involve agriculture, and a new feasibility study suggests that one of them—spreading crushed rock on farm fields—deserves serious consideration. … [Read more...] about Spreading rock dust on farms could be a major climate action
"The sooner you start socking away part of your paycheck for retirement, the easier it is to hit your goals. If you wait until late in your career to start, your goal could be simply out of reach unless you take a second job or win the lottery." That axiom is a bit like how we've treated carbon emissions: when governments started negotiating to limit greenhouse gases in the early 1990s, the agreed-upon goal of limiting global warming to 2 degrees Celsius was pretty doable. The continued rise of emissions since then has turned that into a tall task, while the 1.5 degree Celsius aspiration added to the recent Paris agreement is even taller. … [Read more...] about A not-so-modest proposal to remove atmospheric carbon dioxide
The international agreement contains both legally binding and voluntary components. This awkward structure was necessary because a treaty would face certain rejection in the United States Senate. Temperature goals, and much of the framework, are legally binding, but details like the emissions pledges and the amount of funding for developing countries remain non-binding. … [Read more...] about Paris climate negotiations produce an agreement
