Study: Outdoor Air Pollution is "Largest Existential Threat to Human and Planetary Health". Inside Climate News has a summary; here's the intro: "Since the turn of the century, global deaths attributable to air pollution have increased by more than half, a development that researchers say underscores the impact of pollution as the "largest existential threat to human and planetary health." The findings, part of a study published Tuesday in The Lancet Planetary Health, found that pollution was responsible for an estimated 9 million deaths around the world in 2019. Fully half of those fatalities, 4.5 million deaths, were the result of ambient, or outdoor, air pollution, which is typically emitted by vehicles and industrial sources like power plants and factories. The number of deaths that can be attributed to ambient air pollution has increased by about 55 percent—to 4.5 million from 2.9 million—since the year 2000..."
Pollution Caused 1 In 6 Deaths From 2015-'19: More perspective and links via Climate Nexus: "Pollution killed 9 million people, every year, from 2015 to 2019, even as deaths from indoor air pollution fell due to increases from other sources of pollution, including fossil fuel combustion, a study published this morning in The Lancet Planetary Health reveals. "The bad news is that it's not decreasing," Philip Landrigan, director of the Global Public Health Program and Global Pollution Observatory at Boston College, told the AP. "We're making gains in the easy stuff and we're seeing the more difficult stuff, which is the ambient (outdoor industrial) air pollution and the chemical pollution, still going up." Death rates are worst in Africa and Asia; the U.S. is the only fully industrialized nation in the top (worst) 10 countries in terms of total pollution deaths. "Exposure to (tiny pollution particles) like that generated from the burning of fossil fuels is causal for heart disease and death." Dr. Renee Salas, an emergency room doctor and Harvard professor who wasn't part of the study, told the AP. While very few deaths are directly attributed to pollution on death certificates, causes of death like heart disease, stroke, lung cancer, other lung issues and diabetes that are "tightly correlated" with pollution by epidemiological studies, and "that cannon of information constitutes causality," Landrigan said. The study counted deaths from numerous types of pollution including water and toxic chemical pollution, but air pollution caused the vast majority of deaths. "While people focus on decreasing their blood pressure and cholesterol," Salas said, "few recognize that the removal of air pollution is an important prescription to improve their heart health."

Hydropower Generation Dipping on the Colorado River System. The Colorado Sun describes how perpetual drought is impacting power generation; here's a clip: "...One of the upsides to hydropower in general is that it can be made available quickly on-demand, essentially flipped on or off by releasing more or less water through a dam. "It's our largest low- or no-carbon emissions energy source that we can turn on and off when we need it," Adrienne Marshall, an assistant professor of geology and geological engineering at the Colorado School of Mines, said. "At the same time, our ability to generate hydropower is significantly threatened by drought." Marshal noted that last year all Western hydropower accounted for about 53% of the renewable energy generated in the Western U.S. and about 16% of total Western grid power generation. (Those renewable numbers, she said, do not count nuclear as renewable.)..."

Shut Down Fossil Fuel Production Sites Early to Avoid Climate Chaos, Says Study. The Guardian explains: "Nearly half of existing fossil fuel production sites need to be shut down early if global heating is to be limited to 1.5C, the internationally agreed goal for avoiding climate catastrophe, according to a new scientific study. The assessment goes beyond the call by the International Energy Agency in 2021 to stop all new fossil fuel development to avoid the worst impacts of global heating, a statement seen as radical at the time. The new research reaches its starker conclusion by not assuming that new technologies will be able to suck huge amounts of CO2 from the atmosphere to compensate for the burning of coal, oil and gas. Experts said relying on such technologies was a risky gamble..."

New Texas Plan for Federal Hurricane Harvey Aid Again Diverts Money Away from Coast. The Texas Tribune has the post; here's an excerpt: "...After the land office awarded $1 billion of the aid last year, giving the city of Houston nothing, the federal Department of Housing and Urban Development accused Bush's office of discriminating against Black and Latino Texans. The land office had an opportunity to correct these inequities as it developed a new spending plan. But an analysis by The Texas Tribune found that the land office is on track to follow a similar pattern as it prepares to allocate the next $1.2 billion of the federal aid. The agency's revised plan will once again send a disproportionately high share of money to inland counties with lower risk of natural disasters. Residents in the counties that will benefit most are also significantly whiter and more conservative than those receiving the least aid, an outcome some Democrats view with suspicion as Bush competes for the Republican nomination for attorney general this month..."
