    Breathe easy. A new study suggests that surgical face masks don’t cause a buildup of carbon dioxide or restrict oxygen, despite opposing claims. The study, on the “Effect of Face Masks on Gas Exchange in Healthy Persons and Patients with COPD,” which was published in the Annals of the American Thoracic Society on Friday, was conducted after a group of Florida residents challenged Florida’s mask-wearing mandate in June, arguing that wearing the protective face coverings could result in the buildup of too much carbon dioxide.

    A research team from Caltech and the UCLA Samueli School of Engineering has demonstrated a promising way to efficiently convert carbon dioxide into ethylene — an important chemical used to produce plastics, solvents, cosmetics and other important products globally. The scientists developed nanoscale copper wires with specially shaped surfaces to catalyze a chemical reaction that reduces greenhouse gas emissions while generating ethylene — a valuable chemical simultaneously. Computational studies of the reaction show the shaped catalyst favors the production of ethylene over hydrogen or methane. A study detailing the advance was published in Nature Catalysis. Currently, ethylene has a global...
  • Wear Your Face Mask And Savor Your CO2 Breath

    This is truly a ‘duh’ moment. When a healthy person wears a face mask, they continuously re-rebreathe a portion of the CO2 that comes out of their lungs. Of course, there are many different types of masks that vary in such CO2 concentration, but the principal remains the same. Breathing air that is too rich in CO2 has its own negative health effects ! Humans breathe in air that is approximately 20.95% oxygen, 78.09% nitrogen, 0.93% argon, and 0.04% (400 ppm) of carbon dioxide. Upon exhaling your breath contains approximately 3.8% CO2. Now, people are not dropping dead because...

    The amount of carbon dioxide in the atmosphere is still rising, even though people are driving and flying less during the COVID-19 pandemic. CO2 reached an all-time daily high on May 3rd, hitting levels that haven’t been seen in the more than 60 years since records began. The annual average is also expected to rise, according to an analysis published today by scientists at the national meteorological service for the UK and the Scripps Institution of Oceanography. They found that the overall amount of CO2 in the atmosphere is still climbing steadily, and that the dramatic changes from the pandemic...

    The huge amount of carbon dioxide we are producing and pumping into the Earth's atmosphere is causing much more damage than previously thought. Rising CO2 levels aren't just responsible not for global warming; they also have a massive impact on the global food system, according to a Science Advances study. An increase in carbon dioxide can significantly reduce the level of micronutrients in certain plants. Researchers studied the effects of the gas on rice and it was found to contain significantly less protein, iron, zinc and B vitamins after exposure to the level of carbon dioxide our atmosphere is expected...

    The United States led the entire world in reducing CO2 emissions last year while also experiencing solid economic growth, according to a newly released report.  “The United States saw the largest decline in energy-related CO2 emissions in 2019 on a country basis – a fall of 140 Mt, or 2.9%, to 4.8 Gt,” The International Energy Agency (IEA) reported on Tuesday. “US emissions are now down almost 1 Gt from their peak in the year 2000, the largest absolute decline by any country over that period.”“A 15% reduction in the use of coal for power generation underpinned the decline in overall US emissions...

    The carbon capture package includes a bill, introduced Wednesday, for the United States to work toward a global goal of planting a trillion trees. It also features an expansion of a tax break approved by Congress in 2018 and signed by President Trump for companies that use carbon capture technology to trap carbon from fossil fuel or industrial plants. The new bill would make the so-called 45Q tax credit permanent, increasing the amount paid to companies and lowering the threshold of captured carbon to qualify for it. Another bill looks to boost research, development, and deployment of carbon capture technology...

    Many on the left love to talk about the social cost of carbon dioxide emissions, but what about the social benefits? A new study by climate, economics, and statistical experts raises serious questions about the most popular social cost of carbon models and finds that carbon dioxide emissions have resulted in net positive benefits for society. This updated information should give policymakers pause as legislative sessions convene across the country. The social cost of carbon (SCC) is an estimate of the long-term dollar cost for each ton of carbon dioxide (CO2) emitted into the atmosphere. The SCC is being used...

    Across the country, policymakers at all levels of government are exploring initiatives to address climate change. New York State’s Climate Leadership and Community Protection Act remains one of the most ambitious, with its requirement that “the statewide electrical demand system will be zero emissions” by 2040. So how do we get to a zero-emission system? The New York Independent System Operator (NYISO) is working on a market enhancement that could not only help lead New York to success, but could also serve as a model for the nation to reduce greenhouse gas emissions. Our proposal is to incorporate the social...

    Hours after Microsoft Corp. pledged to eliminate its carbon emissions within a decade earlier this month, the company was forced to fire up fossil fuel generators to power its corporate campus in Fargo, N.D. The software giant ran the diesel-burning machines for about five hours to keep the lights and heat on for 1,600 employees. It is one of about 100 big companies in the Fargo region ordered to do so by the local electric cooperative, which faced high demand for power. Microsoft receives a significant discount on its electricity rates in exchange for using backup power a few times...

    The next frontier in California’s battle against pollution: lawn equipment. State air regulators are laying long-term plans to phase out gasoline-powered devices like leaf blowers and lawn mowers, saying they can produce more noxious emissions than cars. Plenty of Bay Area cities are already acting: At least eight have banned gas-powered blowers, and more restrict their use during times of day or up to a certain noise level. Novato may soon join the list. “What I think we need to realize is that we have to do something different for climate change in the world,” said Novato Mayor Pro Tem...

    **SNIP** CO2 is a byproduct of many different types of human activity and, as we continue to destroy forests and foliage that help scrub the air and provide humans and other animals with breathable air, the amount of CO2 in our air gradually climbs. Studies have shown that too much CO2 in the air can trigger cognitive issues, decreasing the ability of a person to focus and hinder learning. Getting a few breaths of oxygen-rich “fresh” air tends to clear that up, but in a future where fresh air becomes harder and harder to come by, it could lead to...

    THE HAGUE, Netherlands (AP) — In a ruling hailed as an “immense victory for climate justice,” the Netherlands’ top court ruled Friday in favor of activists who have for years been seeking legal orders to force the Dutch government into cutting greenhouse gas emissions. Activists in a packed chamber of the Supreme Court in The Hague erupted into applause and cheers as Presiding Judge Kees Streefkerk rejected the government’s appeal against earlier rulings ordering the government to cut emissions by at least 25% by the end of 2020 from benchmark 1990 levels. The Supreme Court upheld lower courts’ rulings that...
  • China Proves It: Obama Really Was A Sap

    Remember when President Barack Obama was running around telling everyone how he’d convinced China to get serious about cutting its carbon dioxide emissions? A new report shows that Obama was easily duped. Over the course of three years, Obama met with Chinese President Xi Jinping to, he said, agree to “climate targets” (in 2014), “lay out additional actions” (in 2015), and sign the Paris Agreement (2016). In typical Obama understatement, he declared that “we may see this as the moment that we finally decided to save our planet.” Of course, anyone who looked at what China was promising could see...

    NASA’s Curiosity rover returned some seriously surprising data to Earth earlier this year, with readings of elevated methane levels that were hard to explain. Subsequent tests attempted to pin down the cause of the higher-than-expected readings but scientists have yet to come up with a definitive answer. Now, as questions about methane continue to swirl, scientists studying the behavior of gasses on Mars have noticed that oxygen on the Red Planet also acts much differently than it does on Earth. The observations were made in the Gale Crater, which the rover has called home since it landed there back in...

    Given the relentless drumbeat of terrifying claims about the alleged perils of global warming, uninformed people might be inclined to assume that human use of fossil fuels is causing so much havoc that the atmosphere is in danger of being dominated by carbon dioxide, the most vilified molecule in history. As a matter of scientific fact, CO2 comprises a virtually infinitesimal part of the air that blankets our planet. Over geological time, CO2 has reached as high as 8,000 parts per million. The current concentration of 400 parts per million is at the low end of the average over millions...
