https://www.nytimes.com/2023/09/30/world/europe/germany-ebikes-transportation.html By Melissa Eddy , The New York Times.  Excerpt: Germany’s automakers are facing steep challenges as they convert to battery-powered lineups and confront rising competition from China. But business is booming in another corner of the German transport industry: e-bikes. Sales of bicycles in Germany reached a record 7.36 billion euros, or $7.8 billion, in 2022, with e-bikes accounting for nearly half of sales, according to the German Bicycle Industry Association. The group is forecasting that this year, for the first time, Germans will buy more e-bikes than conventional models. Electric bicycles and scooters are the backbone of what’s known as  micromobility , seen as crucial to cutting the carbon emissions of transportation and helping to ease pollution and congestion in European cities.... 

https://www.science.org/content/article/chemical-cages-could-store-hydrogen-expand-use-clean-burning-fuel By ROBERT F. SERVICE , Science.  Excerpt: Cheap molecular “sponges” made with aluminum can be low-pressure gas tanks. Hydrogen seems like the perfect fuel. By weight it packs more punch than any other fuel. It can be made from water, meaning supply is almost limitless, in principle. And when burned or run through a fuel cell, it generates energy without any carbon pollution. But hydrogen takes up enormous volume, making it impractical to store. Compressing it helps, but is expensive and essentially turns hydrogen storage tanks into high-pressure explosives. Now, a molecular sponge made of organic compounds and cheap aluminum promises a practical solution, holding significant amounts of hydrogen at low pressures. Described in a paper accepted last week at the Journal of the American Chemical Society (JACS), it is the latest in a series of promising metal-organic frameworks (MOFs), a

The agency, which represents countries that make up more than 80% of global energy consumption, projects demand for coal, oil and natural gas will peak before 2030. While greenhouse gas emissions keep rising, the IEA finds that there's still a path to reaching net-zero emissions by 2050 and limit global warming to 1.5 degrees Celsius, or 2.7 degrees Fahrenheit. That's what's needed  to avoid  the the worst effects of climate change, such as catastrophic flooding and deadly heatwaves. ...overall message is more optimistic than the one issued in 2021, when the IEA released its first  Net Zero Roadmap .

Vector-borne diseases are a special worry . A warmer climate favors the mosquito that spreads dengue and may already be fueling a worldwide surge in the debilitating disease. Warming may also have enabled malaria-carrying mosquitoes to flourish in Africa’s cooler highlands and ticks that carry Lyme disease to advance northward. Migratory birds, which ferry cargoes of pathogens such as West Nile virus and influenza across continents, are changing the timing and routes of their journeys, with consequences that have yet to emerge. Then there are the direct effects of heat on the human body. The worsening toll of heat waves is unmistakable, with thousands dying every summer, but researchers are also discerning subtler impacts.

Excerpt: Giant new oil and gas wells that require astonishing volumes of water to fracture bedrock are threatening America’s fragile aquifers. ...energy giants are drilling not just for oil, but for the water they need. ...Along a parched stretch of La Salle County, Texas, workers last year dug some 700 feet deep into the ground, seeking freshwater. Millions of gallons of it. The water wouldn’t supply homes or irrigate farms. It was being used by the petroleum giant BP to frack for fossil fuels. The water would be mixed with sand and toxic chemicals and pumped right back underground — forcing oil and gas from the bedrock. ...Fracking a single oil or gas well can now use as much as 40 million gallons of water or more. These mega fracking projects, called “monster fracks” by researchers, have become the industry norm. They barely existed

https://www.nytimes.com/2023/09/22/business/food-companies-emissions-climate-pledges.html By Julie Creswell , The New York Times. Excerpt: Five years ago McDonald’s said it planned to reduce greenhouse gas emissions by more than a third in parts of its operations by 2030. A few years later, it pledged to be “net zero” — cutting emissions to as close to zero as possible — by 2050. But in its most recent  report , McDonald’s disclosed that things were moving in the wrong direction: The company’s emissions in 2021 were 12 percent higher than its 2015 baseline. McDonald’s is hardly alone. An examination of various climate-related reports and filings for 20 of the world’s largest food and restaurant companies reveals that more than half have not made any progress on their emissions reduction goals or have reported rising emissions levels. The bulk of emissions — in many cases more than 90 percent — come from the companies’ supply chains. In other words, the cows and wheat used to make burge

The White House said in a Thursday fact sheet that agencies should weigh the costs of potential climate damages as they make purchases and put together budget proposals. ...A source briefed on the directive told The Hill that they expect it to also expand the use of climate accounting in environmental reviews for infrastructure projects. “It’s a way to balance climate effects against other economic effects,” said Max Sarinksy, senior attorney at the Institute for Policy Integrity at the New York University School of Law. For example, he said, the “social cost of carbon offers even stronger support for the purchase of electric vehicles because you would add the climate cost savings to the budgetary cost sav

https://www.npr.org/2023/09/13/1199273629/climate-change-exacerbates-deadly-floods-worldwide By Rebecca Hersher ,   Lauren Sommer , NPR.  Excerpt: Catastrophic floods in eastern Libya killed at least 3,958 people, according to the United Nations. The disaster comes after a string of deadly floods around the world this month, from China to Brazil to Greece. In every case, extremely heavy rain was to blame. The enormous loss of life on multiple continents reinforces the profound danger posed by climate-driven rain storms, and the need for better warning systems and infrastructure to protect the most vulnerable populations. Climate change  makes heavy rain more common,  even in arid places where the total amount of precipitation is small. That's because a hotter atmosphere can hold more moisture. Everyday rainstorms, as well as bigger storms such as hurricanes, are increasingly dangerous as a result. Human-caused warming made the extreme rainfall in Libya 50 times more likely to happe

https://www.nytimes.com/2023/09/17/climate/california-climate-disclosure-law.html By Coral Davenport , The New York Times.  Excerpt: Gov. Gavin Newsom of California said that he would sign  a landmark climate bill that passed the state’s legislature last week  requiring major companies to publicly disclose their greenhouse gas emissions, a move with national and global repercussions. The new law will require about 5,000 companies to report the amount of greenhouse gas pollution that is directly emitted by their operations and also the amount of indirect emissions like employee travel, waste disposal and supply chains. Climate policy advocates have long argued that such disclosures are an essential first step in efforts to harness financial markets to rein in planet-warming pollution. For example, when investors are made aware of the climate-warming impacts of a company, they may choose to steer their money elsewhere. The law would apply to public and private businesses that make more t

Straddling that split is one man: Sultan al-Jaber. He founded the renewable energy company, Masdar, which has invested billions of dollars in zero-emissions energy technologies like wind and solar power across 40 countries. Simultaneously, he directs Adnoc, the national oil company, a behemoth that makes Masdar look minuscule. Adnoc pumps millions of barrels of oil per day and aims to spend $150 billion over the next five years, mostly to ramp up its output. And this year, the United Nations has in effect vested Mr. al-Jaber with one of humanity’s most pressing tasks: steering its annual global climate negotiations [COP 2023; United Nations F

The projects are essential to meeting the U.S. goal of eliminating all planet-warming carbon emissions from the nation’s electricity supply by 2035, analysts say. Together, they could generate almost 2000 gigawatts of electricity—exceeding the total capacity of the country’s existing power plants. Most of these projects, however, have been stuck in limbo for years, waiting in what energy insiders call the “interconnection queue.” One contributor to the bottleneck: mathematical simulations that SPP and other operators use
