Atmospheric carbon dioxide hits new peak in 2023, growing at near-record rate – “Not only is CO2 continuing to increase despite efforts to reduce emissions, but it’s increasing faster than it was 10 or 20 years ago”

By Seth Borenstein 5 June 2023 (AP News) – The cause of global warming is showing no signs of slowing as heat-trapping carbon dioxide in Earth’s atmosphere increased to record highs in its annual Spring peak, jumping at one of the fastest rates on record, officials announced Monday. Carbon dioxide levels in the air are now the […]

35 vintage photos taken by the EPA reveal what American cities looked like before pollution was regulated

By James Pasley 8 June 2023 (Insider) – Don’t let the soft, sepia tones fool you. The United States used to be dangerously polluted. Before President Richard Nixon created the Environmental Protection Agency in 1970, the environment and its well-being was not a federal priority. In the early 1970s, the EPA launched the “The Documerica […]

Kansas wheat harvest in 2023 expected to be historically small due to two-year drought

By Morgan Mobley 5 June 2023 (KCTV) – Kansas has been called the country’s breadbasket. Now, wheat farmers in the state will reap their smallest harvest in more than 60 years. This will go directly down the chain, from farmers to consumers at the grocery store. Kansas flour mills will likely have to buy wheat […]

Allstate joins State Farm in suspending new policies in California – “The cost to insure new home customers in California is far higher than the price they would pay for policies due to wildfires, higher costs for repairing homes, and higher reinsurance premiums”

By Ryan Mac 4 June 2023 (The New York Times) – California property owners hoping to open new insurance policies are no longer able to do so with one of the nation’s largest homeowner insurance companies. Allstate, the state’s fourth-largest property and casualty insurance provider, has stopped selling new home, condominium or commercial insurance policies in California, […]

New York City air quality hits worst level on record as smoke from Canada wildfires engulfs the Northeast U.S. – “I can taste the air”

By Mike Ives and Liam Stack 7 June 2023 (The New York Times) – The sky in New York City rapidly darkened on Wednesday afternoon, as a plume of smoke from Canadian wildfires approached the nation’s largest city and sent the air quality index soaring past 324, the worst since the Environmental Protection Agency began […]

Change Over Time in (a) US Life Expectancy and (b) US Life Expectancy Gap and Rank Relative to Populous Countries (Population>500000), 1950-2021. Phase 1=1950–1954; phase 2=1955–1973; phase 3=1974–1982; phase 4=1983–2009; phase 5=2010–2019; phase 6=2020–2021. Bars plot the difference in life expectancy between the United States and the populous country (population >500000) with the highest life expectancy in the given year. The country with the highest life expectancy was Norway in 1950–1962 and 1976–1977, Sweden in 1963 and 1965–1975, the Netherlands in 1964, Japan in 1978–2007, Macao in 2008–2010, and Japan in 2011–2021. The line graph plots US rank relative to other populous countries, with higher rank denoting lower US life expectancy. Source: Author’s calculations based on UN data. Graphic: Steven H.

U.S. has been falling behind on life expectancy for decades – Between 1933 and 2021, 56 countries achieved higher life expectancy than U.S. – “Americans are sicker and die earlier than people in dozens of countries”

By Olivia Trani 1 June 2023 (VCU) – When it comes to public health, the United States is at a disadvantage compared with other developed countries. Americans experience more illness, have less access to health care and pay more for health services than citizens in other high-income countries. Americans also die earlier – and have been doing so […]

One year after they were murdered, their work must go on – Forest defender Bruno Araújo Pereira and journalist Dom Phillips were assassinated in Brazil on 5 June 2022

By Katharine Viner 1 June 2023 (The Guardian) – Forest defenders should not be killed for exposing crimes. Journalists should not be killed for reporting facts. But, one year ago, the Guardian was devastated by the awful news that in the Amazon rainforest, two lives had been taken on the frontline of the battle to protect the […]

Map showing the number of subglobal climate (two local exposure boundaries), functional integrity, surface water, groundwater, nitrogen, phosphorus and aerosol safe and just Earth system boundaries (ESBs) currently transgressed by location. No more than seven of these eight metrics have their ESBs transgressed in any one pixel. Since climate is a globally defined ESB, we use wet bulb temperatures of over 35°C for at least 1-day per year and low-elevation coastal zones (

Earth is “really quite sick now” and in danger zone in nearly all ecological ways, study says – “We are moving in the wrong direction on basically all of these”

By Seth Borenstein 31 May 2023 (AP News) – Earth has pushed past seven out of eight scientifically established safety limits and into “the danger zone,” not just for an overheating planet that’s losing its natural areas, but for the well-being of people living on it, according to a new study. The study looks not just […]

Land around the U.S. is sinking. Here are some of the fastest areas.

By Kasha Patel 30 May 2023 (The Washington Post) – Imagine Earth’s surface is like a stack of pancakes. The pancakes, or layers of soil and rocks, may appear fairly evenly stacked and fluffy. Over time though, the stack can become compressed, thinner and shorter. Scientists observe this downward motion of land, called land subsidence, […]

Seaweed full of flesh-eating bacteria hitting Florida, creating a “perfect pathogen storm”

By Jess Thomson 30 May 2023 (Newsweek) – The massive blob of seaweed creeping across the Atlantic Ocean toward Florida may contain deadly flesh-eating bacteria. The 5,000-mile wide clump of seaweed is made up of sargassum seaweed, which has bloomed massively to form the “Great Atlantic Sargassum Belt.” A study from Florida Atlantic University published […]
