WMO annual report highlights continuous advance of climate change – “While greenhouse gas emissions continue to rise and the climate continues to change, populations worldwide continue to be gravely impacted by extreme weather and climate events”

Geneva, 21 April 2023 (WMO) – From mountain peaks to ocean depths, climate change continued its advance in 2022, according to the annual report from the World Meteorological Organization (WMO). Droughts, floods, and heatwaves affected communities on every continent and cost many billions of dollars. Antarctic sea ice fell to its lowest extent on record […]

Ocean plastic pollution reaches “unprecedented” levels – The Great Pacific Garbage Patch is now so huge and permanent that a coastal ecosystem is thriving on it – “The problem is getting bigger and bigger by the minute”

By Ivana Kottasová 18 April 2023 (CNN) – Scientists have found thriving communities of coastal creatures, including tiny crabs and anemones, living thousands of miles from their original home on plastic debris in the Great Pacific Garbage Patch – a 620,000 square mile swirl of trash in the ocean between California and Hawaii. In a new study published in the Nature […]

Poverty is the 4th greatest cause of U.S. deaths – “Poverty silently killed 10 times as many people as all the homicides in 2019. And yet, homicide, firearms, and suicide get vastly more attention.” 

By David Danelski 17 April 2023 (UCR) – Poverty has long been linked to shorter lives. But just how many deaths in the United States are associated with poverty? The number has been elusive – until now. A University of California, Riverside, (UCR) paper published Monday, 17 April 2023, in the Journal of the American […]

Global rice shortage in 2023 is set to be the biggest in 20 years – “At the global level, the most evident impact of the global rice deficit has been, and still is, decade-high rice prices”

By Lee Ying Shan 18 April 2023 (CNBC) – From China to the U.S. to the European Union, rice production is falling and driving up prices for more than 3.5 billion people across the globe, particularly in Asia-Pacific – which consumes 90% of the world’s rice. The global rice market is set to log its largest […]

The European model shows temperatures across Southeast Asia rising well above normal on Monday, 17 April 2023. Numerous heat records were broken across Southeast Asia, China and other parts of the continent in mid-April, with Thailand in particular experiencing unusually extreme conditions. Weather historian Maximiliano Herrera described it as the “worst April heat wave in Asian history.” Graphic: WeatherBell.com

Historic Asia heat breaks hundreds of records, with extremes in Thailand and China – Thailand recorded its all-time hottest temperature – “Worst April heat wave in Asian history”

By Dan Stillman 17 April 2023 (The Washington Post) – Numerous heat records have been broken across Southeast Asia, China and other parts of the continent in recent days as the region remains in the grip of a dangerously scorching heat wave, with Thailand in particular experiencing unusually extreme conditions. Weather historian Maximiliano Herrera is describing […]

Map showing the physical imprint and consequences of extreme summer heat across the Pacific Northwest in 2021. The June-August (JJA) 2021 seasonally averaged temperature anomalies (t2m) over North America calculated from the 1951-1980 mean of ERA5 Reanalysis, with the Pacific Northwest region (PNW; 42–53 °N, 124–115 °W, dark blue box) highlighted. The year 2021 (dashed black line) is shown relative to the distribution (black line) and probability density (red line) curves of JJA t2m values over the period 1950–2021 for the PNW region. White exes indicate the locations of all tree-ring chronology predictors used in the subsequent JJA t2m reconstruction. Graphic: Heeter, et al., 2023 / npj Climate and Atmospheric Science

The summer of 2021 was the Pacific Northwest’s hottest in a millennium – “The tree scorch was shocking. The average summer temperatures were extraordinarily away from the norm.”

By Sid Perkins 14 April 2023 (Science News) – A two-week-long heat wave in the Pacific Northwest in 2021 helped make that summer a record breaker for the region (SN: 7/7/21). Now, tree ring data from the area’s forests reveal that the summer of 2021 was also the region’s hottest of the last millennium. The average temperature […]

Physiological response curves may shift as soil microbiomes respond to drought. In the short term (minutes to days), physiological acclimation may help to sustain function, such as soil carbon decomposition. Over weeks to decades, community shifts and evolution could alter response curves to maintain functioning under dry conditions. Broken lines indicate potential variation in the breadth of the shifted response curves. Graphic: Evans, et al., 2022 / Functional Ecology

Droughts destroying Earth’s biggest carbon sink on land: study – If more carbon-releasing microbes survive than carbon-sequestering microbes, we could end up with carbon-depleted soils

By Mark Waghorn 12 April 2023 (SWNS) – Droughts are destroying Earth’s biggest carbon sink on land, according to new research. Soil stores more greenhouse gas than plants and the atmosphere combined – thanks to the microbes that live in it. Moisture plays a key role in the process. Lack of rainfall is disrupting this […]

Average age at death in U.S. counties, 2020. Data: CDC Death Records. The U.S. is experiencing the greatest gap in life expectancy across regions in the last 40 years.

Americans are dying younger, and where you live makes a big difference – Americans born in Mississippi and Florida may die 20 years younger than their peers born in Colorado and California

By Jeremy Ney 12 April 2023 (TIME) – The average U.S. life expectancy has hit its worst decline in 100 years and America’s standing is dismal among peer nations. But the average obscures a more complex story. The United States is facing the greatest divide in life expectancy across regions in the last 40 years. Research from American […]

Earth has second-warmest March in 2023 even before arrival of planet-heating El Niño – It was the 529th consecutive month to feature temperatures above the 20th-century average – “What I still find shocking is that the last eight years were the eight warmest years on record”

By Matthew Cappucci 7 April 2023 (The Washington Post) – March 2023 will go down in the books as tying for the second warmest March on record. That’s according to the Copernicus Climate Change Service of the European Union. Temperatures globally were several degrees above average in most places outside the western U.S., where a […]

Global monthly mean atmospheric carbon dioxide, 1979-2022. The global surface average for CO2 rose by 2.13 parts per million (ppm) to 417.06 ppm, roughly the same rate observed during the last decade. Atmospheric CO2 is now 50% higher than pre-industrial levels. 2022 was the 11th consecutive year CO2 increased by more than 2 ppm, the highest sustained rate of CO2 increases in the 65 years since monitoring began. Prior to 2013, three consecutive years of CO2 growth of 2 ppm or more had never been recorded. The Global Monitoring Division of NOAA/Earth System Research Laboratory has measured carbon dioxide and other greenhouse gases for several decades at a globally distributed network of air sampling sites. This graph shows monthly mean abundance of carbon dioxide globally averaged over marine surface sites. Graphic: NOAA Global Monitoring Laboratory

Greenhouse gases continued to increase rapidly in 2022 – Carbon dioxide, methane, and nitrous oxide rise further into uncharted levels – “Greenhouse gas emissions continue to rise at an alarming pace and will persist in the atmosphere for thousands of years”

5 April 2023 (NOAA) – Levels of carbon dioxide (CO2), methane and nitrous oxide, the three greenhouse gases emitted by human activity that are the most significant contributors to climate change, continued their historically high rates of growth in the atmosphere during 2022, according to NOAA scientists.  The global surface average for CO2 rose by 2.13 […]
