Nvidia will want buyers to choose its new, more expensive flagships over the last generation, of course, so it might start withdrawing the RTX 2080 and RTX 2080 Ti from market soon. IThome predicts the RTX 3080 and 3080 Ti will be announced on September 17, so we could discover the largest US chipmaker’s plans in just over two months. … [Read more...] about Report: Nvidia has ended production of its top Turing RTX cards

Nuclear energiesWhen physicists began to crack the nuclear code in the 1940s, they had no idea that their machinations would end of unlocking one of the most perplexing mysteries of astronomy: how stars work. Prior to this time, scientists had tried all sorts of attempts to reconcile the age of the Earth as revealed by geology and paleontology (billions of years) with all the known physical ways to keep the sun burning so brightly. These attempts, as a rule, failed quite miserably, with even the best explanations only reaching a few million years. … [Read more...] about What’s the most amazing thing about the universe?
The majority of this capture potential comes from the US, China, India, and Brazil. Many other countries could offset a meaningful portion of their emissions this way, but these four countries have the most suitable farmland. For the US and China, it could offset up to 5 to 10 percent of emissions in 2030. India could offset as much as 40 percent, and Brazil could fully offset its emissions—though these numbers represent technical capacity, which would require a very strong commitment to this scheme. … [Read more...] about Spreading rock dust on farms could be a major climate action
At this point, hitting those targets very likely requires more than just shifting away from fossil fuels. We’ll also need “negative emissions”—activities that absorb carbon dioxide from smokestacks or directly from the atmosphere—in order to squeeze under the line. It’s a simple concept but a very big challenge. Some nascent negative emission technologies exist, like capturing CO2 from smokestacks and pumping it into underground reservoirs. Other proposals, however, sound pretty wild and may not work—like dumping iron dust into the oceans to spur plankton growth. … [Read more...] about A not-so-modest proposal to remove atmospheric carbon dioxide
Rather than prescribe some common emissions target, the negotiations took a “bottom-up” approach, with nations each submitting their own emissions pledges. Current pledges are only good enough to limit 21st century warming to around 3°C. But a key part of the agreement is a framework for revisiting emissions pledges every 5 years, with the goal being that those pledges are ratcheted down over time. To that end, it states that nations will “aim to reach global peaking of greenhouse gas emissions as soon as possible” and reach net-zero emissions “in the second half of this century”. While the details remain to be filled in, the agreement also calls for transparent reporting of emissions to keep nations to their pledges. … [Read more...] about Paris climate negotiations produce an agreement
