Japan's central government has declared a third state of emergency due to the COVID-19 pandemic with new restrictions imposed in Tokyo, Osaka, Kyoto and Hyogo prefectures. Local leaders requested the move as they face a sharp rise in new coronavirus cases. From a report: The declaration comes as Tokyo prepares to host the Summer Olympics, slated to begin in July, and just before Japan enters one of its biggest holiday seasons, Golden Week, in late April. The emergency measures stop short of a full lockdown, but they impose limits on restaurants and other businesses. The strictest rules will apply to places that sell alcohol or offer karaoke. They'll be asked to close entirely, while many other establishments will close at 8 p.m. The new policies, which carry fines but largely rely on voluntary compliance, go into effect on Sunday and will run through at least May 11. Nationwide, Japan is seeing spikes in new cases and hospitalizations, both of which are soaring toward the record heights that were seen at the start of 2021. Some 5,452 people tested positive for the coronavirus on Thursday, according to the Ministry of Health, Labour and Welfare.

A group of hackers executed a ransomware attack on Hoya, marking the second successful attack suffered by the Japanese firm in two years. From a report: "We can confirm that Hoya Vision Care US has experienced a cyberattack. Based on our initial forensics, the disruption appears to have been limited to our United States systems," a Hoya spokesperson said. "After identifying the threat, we quickly took action to contain it and contacted law enforcement. The company has engaged external experts to determine the nature and scope of this event. We will provide updates as more information becomes available." Hoya, named after the West Tokyo neighborhood where it was founded in 1941, is a glassmaker with about 37,000 employees worldwide and about $5 billion in annual revenue. The company gets last year 65% of its sales from contact lenses and glasses, while the rest comes Information technology devices and services such glass substrate used in the manufacturing of semiconductors and hard disk drives, according to 2020 company's report. The hacker group called Astro Team said on its blog last week that it targeted Hoya servers and stole about 300 gigabytes of confidential corporate data including finance, production, email messages, passwords and safety reports. In 2019, Hoya suffered a major cyberattack, infectong over 100 computers and forcing the company to shut down its factories for three days.

The UK government will look into the national security implications of U.S. group Nvidia's purchase of British chip designer ARM, it said on Monday, putting a question mark over the $40 billion deal. From a report: Digital minister Oliver Dowden said on Monday he had issued a so-called "intervention notice" over the sale of ARM by Japan's SoftBank to Nvidia. "As a next step and to help me gather the relevant information, the UK's independent competition authority will now prepare a report on the implications of the transaction, which will help inform any further decisions," he said. Nvidia said it did not believe the deal posed any material national security issues.

The Japanese government has been forced to quickly retire an animated character it had hoped would win support for its decision this week to release more than 1m tonnes of contaminated water from the Fukushima Daiichi nuclear power plant into the sea. From a report: Although the water will be treated before being discharged, it will still contain tritium, a radioactive hydrogen isotope represented on a government website by a cute fish-like creature with rosy cheeks. The character's appearance in an online flyer and video on the reconstruction agency's website angered Fukushima residents. "It seems the government's desire to release the water into the sea takes priority over everything," Katsuo Watanabe, an 82-year-old Fukushima fisher, told the Kyodo news agency. "The gap between the gravity of the problems we face and the levity of the character is huge."

Riken Komatsu, a local writer, tweeted: "If the government thinks it can get the general public to understand just by creating a cute character, it is making a mockery of risk communication." Social media users named the character Tritium-kun -- or Little Mr Tritium -- an apparent reference to Pluto-kun, who appeared in the mid-1990s to soften the image of plutonium on behalf of Japan's nuclear industry. The reconstruction agency, which oversees recovery efforts in the region destroyed by the March 2011 earthquake, tsunami and nuclear meltdown, removed the promotional material on Wednesday, a day after it first appeared. Experts say tritium is harmful to humans only in large doses, and that with dilution the treated water poses no scientifically detectable risk.

According to the Associated Press, Japan's government decided it will start releasing treated radioactive water accumulated at the crippled Fukushima nuclear plant into the Pacific Ocean in two years. From the report: Under the basic plan adopted Tuesday by the ministers, Tokyo Electric Power Company Holdings, also known as TEPCO, will start releasing the water in about two years after building a facility and compiling release plans adhering to safety requirements. It said the disposal of the water cannot be postponed further and is necessary to improve the environment surrounding the plant so residents can live there safely. TEPCO says its water storage capacity of 1.37 million tons will be full around fall of 2022. Also, the area now filled with storage tanks will have to be freed up for building new facilities needed for removing melted fuel debris from inside the reactors and for other decommissioning work that's expected to start in coming years.

In the decade since the tsunami disaster, water meant to cool the nuclear material has constantly escaped from the damaged primary containment vessels into the basements of the reactor buildings. To make up for the loss, more water has been pumped into the reactors to continue to cool the melted fuel. Water is also pumped out and treated, part of which is recycled as cooling water, and the remainder stored in 1,020 tanks now holding 1.25 million tons of radioactive water. Those tanks that occupy a large space at the plant interfere with the safe and steady progress of the decommissioning, Economy and Industry Minister Hiroshi Kajiyama said. The tanks also could be damaged and leak in case of another powerful earthquake or tsunami, the report said.

Releasing the water to the ocean was described as the most realistic method by a government panel that for nearly seven years had discussed how to dispose of the water. The report it prepared last year mentioned evaporation as a less desirable option. About 70% of the water in the tanks is contaminated beyond discharge limits but will be filtered again and diluted with seawater before it is released, the report says. According to a preliminary estimate, gradual releases of water will take more than 30 years but will be completed before the plant is fully decommissioned. Japan will abide by international rules for a release, obtain support from the International Atomic Energy Agency and others, and ensure disclosure of data and transparency to gain understanding of the international community, the report said. China blasted the Japanese government for being "extremely irresponsible," and warned that it might take action. "The Japanese side has yet to exhaust all avenues of measures, disregarded domestic and external opposition, has decided to unilaterally release the Fukushima plant's nuclear waste water without full consultation with its neighboring countries and the international community," the foreign ministry statement said. "This action is extremely irresponsible and will pose serious harm to the health and safety of the people in neighboring countries and the international community."

South Korea also isn't happy with Japan's decision. "The government expresses strong regret over the Japanese government's decision to release contaminated water from the Fukushima nuclear plant into the ocean," said Koo Yoon-cheol, head of South Korea's Office for Government Policy Coordination.

Nvidia said it's offering the company's first server microprocessors, extending a push into Intel's most lucrative market with a chip aimed at handling the most complicated computing work. Intel shares fell more than 2% on the news. From a report: The graphics chipmaker has designed a central processing unit, or CPU, based on technology from Arm, a company it's trying to acquire from Japan's SoftBank Group. The Swiss National Supercomputing Centre and U.S. Department of Energy's Los Alamos National Laboratory will be the first to use the chips in their computers, Nvidia said Monday at an online event. Nvidia has focused mainly on graphics processing units, or GPUs, which are used to power video games and data-heavy computing tasks in data centers. CPUs, by contrast, are a type of chip that's more of a generalist and can do basic tasks like running operating systems. Expanding into this product category opens up more revenue opportunities for Nvidia.

Founder and Chief Executive Officer Jensen Huang has made Nvidia the most valuable U.S. chipmaker by delivering on his promise to give graphics chips a major role in the explosion in cloud computing. Data center revenue contributes about 40% of the company's sales, up from less than 7% just five years ago. Intel still has more than 90% of the market in server processors, which can sell for more than $10,000 each. The CPU, named Grace after the late pioneering computer scientist Grace Hopper, is designed to work closely with Nvidia graphics chips to better handle new computing problems that will come with a trillion parameters. Systems working with the new chip will be 10 times faster than those currently using a combination of Nvidia graphics chips and Intel CPUs. The new product will be available at the beginning of 2023, Nvidia said.

New submitter evaverdeazul shared this report from Japan Today: The Japanese government is poised to release treated radioactive water accumulated at the crippled Fukushima nuclear plant into the sea despite opposition from fishermen, sources familiar with the matter said Friday. It will hold a meeting of related ministers as early as Tuesday to formally decide on the plan, a major development following over seven years of discussions on how to discharge the water used to cool down melted fuel at the Fukushima Daiichi plant.

The treated water containing radioactive tritium, a byproduct of nuclear reactors, is said to pose little risk to human health because even if one drinks the water, so long as the tritium concentration is low, the amounts of tritium would not accumulate in the body and would soon be excreted. There is also no risk of external exposure even if the water comes in contact with skin. Still, concerns remain among Japan's fisheries industry and consumers as well as neighboring countries such as South Korea and China.

The government has said it cannot continue postponing a decision on the disposal issue, given that the storage capacity of water tanks at the Fukushima complex is expected to run out as early as fall next year. It asserts that space needs to be secured on the premises, such as for keeping melted fuel debris that will be extracted from the damaged reactors, to move forward with the decades-long process of scrapping the complex.

Plant operator Tokyo Electric Power Company Holdings Inc (TEPCO) says it will take around two years for the discharge to start.

Cosmic rays are causing an estimated 30,000 to 40,000 malfunctions in domestic network communication devices in Japan every year, a Japanese telecom giant found recently. From a report: Most so-called "soft errors," or temporary malfunctions, in the network hardware of Nippon Telegraph and Telephone Corp. are automatically corrected via safety devices, but experts said in some cases they may have led to disruptions. It is the first time the actual scale of soft errors in domestic information infrastructures has become evident. Soft errors occur when the data in an electronic device is corrupted after neutrons, produced when cosmic rays hit oxygen and nitrogen in the earth's atmosphere, collide with the semiconductors within the equipment. Cases of soft errors have increased as electronic devices with small and high-performance semiconductors have become more common. Temporary malfunctions have sometimes led to computers and phones freezing, and have been regarded as the cause of some plane accidents abroad. Masanori Hashimoto, professor at Osaka University's Graduate School of Information Science and Technology and an expert in soft errors, said the malfunctions have actually affected other network communication devices and electrical machineries at factories in and outside Japan.

Physicist Isamu Akasaki, a co-winner of the 2014 Nobel Prize in physics for inventing the world's first efficient blue light-emitting diodes, has died, Meijo University said Friday. He was 92. The Japan Times reports: Akasaki, born in Kagoshima Prefecture, graduated from Kyoto University in 1952 before working at Matsushita Electric Industrial Co., now Panasonic Corp. He started working at Nagoya University as a professor in 1981 and was later given an honorary title. In 2014, he shared the Nobel Prize with physicist Hiroshi Amano, professor at the university, and Japan-born American Shuji Nakamura, professor at the University of California, Santa Barbara.

Akasaki, when he was a professor at Nagoya University, worked with Amano to produce gallium nitride crystals, and succeeded in 1989 in creating the world's first blue LED. Akasaki was honored in 1997 by the Japanese government with the Medal with Purple Ribbon, an honor bestowed on those who have made contributions to academic and artistic developments.

An anonymous reader quotes a report from the BBC: The cherry blossom season, Japan's traditional sign of spring, peaked at the earliest date since records began 1,200 years ago, research shows. The 2021 season in the city of Kyoto peaked on 26 March, according to data collected by Osaka University. Increasingly early flowerings in recent decades are likely to be as a result of climate change, scientists say. The records from Kyoto go back to 812 AD in imperial court documents and diaries. The previous record there was set in 1409, when the season reached its peak on March 27.

"In Kyoto, records of the timing of celebrations of cherry blossom festivals going back to the 9th Century reconstruct the past climate and demonstrate the local increase in temperature associated with global warming and urbanization," according to an earlier paper published in the scientific journal Biological Conservation. Since about 1800, the data suggest the peak date in Kyoto has gradually been moving back from mid-April towards the beginning of the month. This year, the season began in Hiroshima on March 11, eight days earlier than the previous record, which was set in 2004, according to Japan Forward.

For 30 years David E. Sanger has been covering foreign policy and nuclear proliferation for The New York Times — twice working on Pulitzer Prize-winning teams. But now as American and Chinese officials meet in Alaska, Sanger argues that China's power doesn't come from weapons — nuclear or otherwise: Instead, it arises from their expanding economic might and how they use their government-subsidized technology to wire nations be it Latin America or the Middle East, Africa or Eastern Europe, with 5G wireless networks intended to tie them ever closer to Beijing. It comes from the undersea cables they are spooling around the world so that those networks run on Chinese-owned circuits. Ultimately, it will come from how they use those networks to make other nations dependent on Chinese technology. Once that happens, the Chinese could export some of their authoritarianism by, for example, selling other nations facial recognition software that has enabled them to clamp down on dissent at home.

Which is why Jake Sullivan, Mr. Biden's national security adviser, who was with Secretary of State Antony J. Blinken for the meeting with their Chinese counterparts in Anchorage, warned in a series of writings in recent years that it could be a mistake to assume that China plans to prevail by directly taking on the United States military in the Pacific. "The central premises of this alternative approach would be that economic and technological power is fundamentally more important than traditional military power in establishing global leadership," he wrote, "and that a physical sphere of influence in East Asia is not a necessary precondition for sustaining such leadership...."

Part of the goal of the Alaska meeting was to convince the Chinese that the Biden administration is determined to compete with Beijing across the board to offer competitive technology, like semiconductor manufacturing and artificial intelligence, even if that means spending billions on government-led research and development projects, and new industrial partnerships with Europe, India, Japan and Australia... But it will take months, at best, to publish a broad new strategy, and it is unclear whether corporate America or major allies will get behind it.

After a year in which most people were stuck indoors, it should come as little surprise that streaming platforms skyrocketed in popularity over the past 12 months. For the first time ever, subscriptions to streaming services surpassed one billion, reaching 1.1 billion globally. From a report: At the same time, box office receipts plummeted because movie theaters across the world were closed for a significant part of 2020. Global ticket sales tapped out at $12 billion, with North America accounting for $2.2 billion of that haul. Though the circumstances aren't comparable, worldwide box office receipts totaled $42.5 billion in 2019, with $11.4 billion coming from domestic theaters. Still, it marks a 72% year-over-year decline. These statistics come from the Motion Pictures Association's annual theme report, which is conducted by the entertainment industry trade group and intends to analyze how film, television and streaming content performs yearly.

The 2020 study covers a year that was overshadowed by the coronavirus pandemic, making some of the data understandably skewed and difficult to compare box office totals between countries. In Asian countries, particularly in China, the box office has already returned to pre-pandemic levels. That hasn't been the case in the U.S. and Canada, where new movies are few and far between and audiences are returning to theaters at a glacial pace. Outside of North America, the top three box office markets were China ($3 billion), Japan ($1.3 billion), and France ($500 million). Combined, the global theatrical business and home and mobile entertainment market totaled $80.8 billion in revenues in 2020, shrinking by 18% from the $98.3 billion amassed last year. The success of digital home entertainment, which grew 23% to $68.8 billion, helped offset the depleted theatrical box office numbers. In the U.S., subscriptions reached 308.6 million, representing a 32% increase from 2019.

A two-armed robot is helping to prepare soba noodles at an eatery at JR Kaihimmakuhari Station in this Chiba city's Mihama Ward (in Japan), capably boiling the noodles in a strainer, rinsing them and then dipping them in iced water. From a report: The Sobaichi Perie Kaihimmakuhari eatery implemented a collaborative cooking system, with the robot cooking the food and employees adding the dipping sauce or soup and toppings. It is apparently the first time for the cooking robot to be introduced in an actual restaurant setting. Soba stands at railway stations usually have to deal with a constant stream of customers and work under time pressure, resulting in a chronic shortage of human resources. [...] The robot fetches soba noodles from a box with one arm, and places it in a strainer. Then with the other arm, it picks up the strainer and boils the noodles for a minute and 40 seconds, rinses off the viscous film on the surface and then dips the noodles in iced water to bring out their firmness. The robot can cook 150 servings in an hour, substituting the work of about one employee.

The CBC Radio show Quirks and Quarks shares an interesting theory: If you find yourself pondering the marvel of aerodynamics when you fly on a plane, or if you concentrate on the structure of music as it plays, rather than simply listening, you may score high on measures of "systemization," according to University of Cambridge neuroscientist Simon Baron-Cohen.

And if so this may reflect abilities that he thinks may have first evolved in humans between 70,000 and 100,000 years ago, when our human ancestors took a cognitive leap forward. This new capacity enabled them to analyze and understand patterns in the world that would, among other things, facilitate the invention of complex tools from bows to musical instruments. In Baron-Cohen's new book, he argues that humans became "the scientific and technological masters of our planet" because of our brain's "systemizing mechanism."

Also, some individuals — particularly those with Autism Spectrum Disorder, are the "hyper-systemizers" of our world. He suggests this should cause us to re-evaluate the capacities and strengths of people with autism... "[F]or the longest time, autism has been really just characterized as a disability, which it is, but with a focus on all the things that autistic people find difficult, what they struggle with. But we know that autism is more than just a disability, that autistic people think differently. Sometimes they have strengths...

"The fact that we can now see a link between those strengths in autism and human invention may change the way we look at autistic people. We might want to see them for who they are, people who think differently and have contributed to human progress."

Myanmar's first satellite is being held on board the International Space Station following the Myanmar coup, while Japan's space agency and a Japanese university decide what to do with it, two Japanese university officials said. Reuters: The $15 million satellite was built by Japan's Hokkaido University in a joint project with Myanmar's government-funded Myanmar Aerospace Engineering University (MAEU). It is the first of a set of two 50 kg microsatellites equipped with cameras designed to monitor agriculture and fisheries. Human rights activists and some officials in Japan worry that those cameras could be used for military purposes by the junta that seized power in Myanmar on Feb. 1. That has put the deployment on hold, as Hokkaido University holds discussions with the Japan Aerospace Exploration Agency (JAXA), the two Hokkaido University officials said.

Japan's Fugaku supercomputer, the world's fastest in terms of computing speed, went into full operation this week, earlier than initially scheduled, in the hope that it can be used for research related to the novel coronavirus. From a report: The supercomputer, named after an alternative word for Mount Fuji, became partially operational in April last year to visualize how droplets that could carry the virus spread from the mouth and to help explore possible treatments for COVID-19. "I hope Fugaku will be cherished by the people as it can do what its predecessor K couldn't, including artificial intelligence (applications) and big data analytics," said Hiroshi Matsumoto, president of the Riken research institute that developed the machine, in a ceremony held at the Riken Center for Computational Science in Kobe, where it is installed. Fugaku, which can perform over 442 quadrillion computations per second, was originally scheduled to start operating fully in the fiscal year from April. It will eventually be used in fields such as climate and artificial intelligence applications, and will be used in more than 100 projects, according to state-sponsored Riken.

In late November, an urgent email popped up in the inbox of Hindustan Syringes & Medical Devices, one of the world's largest syringe makers. It was from UNICEF, the United Nations agency for children, and it was desperately seeking syringes. Not just any would do. These syringes must be smaller than usual. They had to break if used a second time, to prevent spreading disease through accidental recycling. Most important, UNICEF needed them in vast quantities. Now. From a report: "I thought, 'No issues,'" said Rajiv Nath, the company's managing director, who has sunk millions of dollars into preparing his syringe factories for the vaccination onslaught. "We could deliver it possibly faster than anybody else." As countries jostle to secure enough vaccine doses to put an end to the Covid-19 outbreak, a second scramble is unfolding for syringes. Vaccines aren't all that useful if health care professionals lack a way to inject them into people.

Officials in the United States and the European Union have said they don't have enough vaccine syringes. In January, Brazil restricted exports of syringes and needles when its vaccination effort fell short. Further complicating the rush, the syringes have to be the right type. Japan revealed last month that it might have to discard millions of doses of the Pfizer-BioNTech vaccine if it couldn't secure enough special syringes that could draw out a sixth dose from its vials. In January, the Food and Drug Administration advised health care providers in the United States that they could extract more doses from the Pfizer vials after hospitals there discovered that some contained enough for a sixth -- or even a seventh -- person. "A lot of countries were caught flat-footed," said Ingrid Katz, the associate director of the Harvard Global Health Institute. "It seems like a fundamental irony that countries around the world have not been fully prepared to get these types of syringes." The world needs between eight billion and 10 billion syringes for Covid-19 vaccinations alone, experts say. In previous years, only 5 percent to 10 percent of the estimated 16 billion syringes used worldwide were meant for vaccination and immunization, said Prashant Yadav, a senior fellow at the Center for Global Development, a think tank in Washington, and an expert on health care supply chains.

The kingdom is building a $5 billion plant to make green fuel for export and lessen the country's dependence on petrodollars. From a report: Sun-scorched expanses and steady Red Sea breezes make the northwest tip of Saudi Arabia prime real estate for what the kingdom hopes will become a global hub for green hydrogen. As governments and industries seek less-polluting alternatives to hydrocarbons, the world's biggest crude exporter doesn't want to cede the burgeoning hydrogen business to China, Europe or Australia and lose a potentially massive source of income. So it's building a $5 billion plant powered entirely by sun and wind that will be among the world's biggest green hydrogen makers when it opens in the planned megacity of Neom in 2025. The task of turning a patch of desert the size of Belgium into a metropolis powered by renewable energy falls to Peter Terium, the former chief executive officer of RWE AG, Germany's biggest utility, and clean-energy spinoff Innogy SE. His performance will help determine whether a country dependent on petrodollars can transition into a supplier of non-polluting fuels.

"There's nothing I've ever seen or heard of this dimension or challenge," Terium said. "I've been spending the last two years wrapping my mind around 'from scratch,' and now we're very much in execution mode." Hydrogen is morphing from a niche power source -- used in zeppelins, rockets and nuclear weapons == into big business, with the European Union alone committing $500 billion to scale up its infrastructure. Huge obstacles remain to the gas becoming a major part of the energy transition, and skeptics point to Saudi Arabia's weak track record so far capitalizing on what should be a competitive edge in the renewables business, especially solar, where there are many plans but few operational projects. But countries are jostling for position in a future global market, and hydrogen experts list the kingdom as one to watch.

The U.K. is hosting 10 projects to heat buildings with the gas, China is deploying fuel-cell buses and commercial vehicles, and Japan is planning to use the gas in steelmaking. U.S. presidential climate envoy John Kerry urged the domestic oil and gas industry to embrace hydrogen's "huge opportunities." That should mean plenty of potential customers for the plant called Helios Green Fuels. Saudi Arabia is setting its sights on becoming the world's largest supplier of hydrogen -- a market that BloombergNEF estimates could be worth as much as $700 billion by 2050. "You're seeing a more diversified portfolio of energy exports that is more resilient," said Shihab Elborai, a Dubai-based partner at consultant Strategy&. "It's diversified against any uncertainties in the rate and timing of the energy transition." Blueprints are being drawn and strategies are being announced, but it's still early days for the industry. Hydrogen is expensive to make without expelling greenhouse gases, difficult to store and highly combustible. Green hydrogen is produced by using renewable energy rather than fossil fuels. The current cost of producing a kilogram is a little under $5, according to the International Renewable Energy Agency.

Honda Motor will on Friday launch a new car equipped with the world's first certified level 3 autonomous driving technology. Nikkei Asia reports: Industry experts are cautiously watching to see if the Legend, a luxury sedan that operates without driver supervision under certain conditions but requires the driver to assume control of the vehicle within seconds when alerted, can capture enough demand to suggest a way forward for other manufacturers. Honda unveiled the Legend on Thursday at an online press event.

The new model's Traffic Jam Pilot system was approved by Japan's Ministry of Land, Infrastructure, Transport and Tourism in November. It can free drivers from driving in congested traffic on an expressway when traveling slower than 50 kilometers per hour. The system automatically accelerates, brakes and steers while monitoring the vehicle's surroundings, using data from high-definition mapping and external sensors. The driver, meanwhile, can enjoy the vehicle's infotainment using the navigation screen but must respond to the system's request for a handover when the vehicle speeds up after the traffic jam eases. The report says Honda is proceeding cautiously, only producing 100 units that will be available only for lease sales. The vehicle will also carry a steep price of $102,000.

One billion years from now, Earth's atmosphere will contain very little oxygen, making it uninhabitable for complex aerobic life. From a report: Today, oxygen makes up around 21 per cent of Earth's atmosphere. Its oxygen-rich nature is ideal for large and complex organisms, like humans, that require the gas to survive. But early in Earth's history, oxygen levels were much lower -- and they are likely to be low again in the distant future. Kazumi Ozaki at Toho University in Funabashi, Japan, and Chris Reinhard at the Georgia Institute of Technology in Atlanta modelled Earth's climatic, biological and geological systems to predict how atmospheric conditions on Earth will change. The researchers say that Earth's atmosphere will maintain high levels of oxygen for the next billion years before dramatically returning to low levels reminiscent of those that existed prior to what is known as the Great Oxidation Event of about 2.4 billion years ago. "We find that the Earth's oxygenated atmosphere will not be a permanent feature," says Ozaki. One central reason for the shift is that, as our sun ages, it will become hotter and release more energy.

The researchers calculate that this will lead to a decrease in the amount of carbon dioxide in the atmosphere as CO2 absorbs heat and then breaks down. Ozaki and Reinhard estimate that in a billion years, carbon dioxide levels will become so low that photosynthesising organisms -- including plants -- will be unable to survive and produce oxygen. The mass extinction of these photosynthetic organisms will be the primary cause of the huge reduction in oxygen. "The drop in oxygen is very, very extreme -- we're talking around a million times less oxygen than there is today," says Reinhard.
