In the grip of global heat – Early Summer 2024 heatwaves in the Northern Hemisphere have been fierce

By Adam Voiland 28 June 2024 (NASA) – It’s only the beginning of the summer season in the Northern Hemisphere, but Earth is already roasting. Scientists from NASA’s Goddard Institute for Space Studies recently reported that May 2024, the hottest May in NASA’s global surface temperature analysis, marked a full year of record-high monthly temperatures. Likewise, NOAA recently reported that January through […]

Melting of Alaska’s Juneau Icefield accelerates, losing snow nearly 5 times faster than in the 1980s – “When you go there the changes from year-to-year are so dramatic that it just hits you over the head”

By Seth Borenstein 2 July 2024 (AP) – The melting of Alaska’s Juneau icefield, home to more than 1,000 glaciers, is accelerating. The snow covered area is now shrinking 4.6 times faster than it was in the 1980s, according to a new study. Researchers meticulously tracked snow levels in the nearly 1,500-square mile icy expanse going back […]

Map showing reduction of stored groundwater in the U.S. Southwest, April 2002 - September 2023. Gravity measurements from the GRACE series of satellites show that the decline in water levels in the Great Basin region from April 2002 to September 2023 has most severely affected portions of southern California (indicated in red). Record snowfall in recent years has not been enough to offset long-term drying conditions and increasing groundwater demands in the U.S. Southwest.

NASA satellites find record snow didn’t offset Southwest U.S. groundwater loss – “In years like the 2022-23 winter, I expected that the record amount of snowfall would really help to replenish the groundwater supply. But overall, the decline continued.”

By James R. Riordon 17 June 2024 (NASA GSFC) – Record snowfall in recent years has not been enough to offset long-term drying conditions and increasing groundwater demands in the U.S. Southwest, according to a new analysis of NASA satellite data [Snowfall Replenishes Groundwater Loss in the Great Basin of the Western United States, but […]

Microplastics found in every human semen sample tested in study – “There is a need for action to avoid additional permanent damage to the planet and the human body”

By Damian Carrington 10 June 2024 (The Guardian) – Microplastic pollution has been found in all human semen samples tested in a study, and researchers say further research on the potential harm to reproduction is “imperative”. Sperm counts in men have been falling for decades and 40% of low counts remain unexplained, although chemical pollution has been implicated by many […]

Maps of near-bottom dissolved oxygen in the continental shelf waters off the United States Pacific Northwest, 1950-2021. About half of the water near the seafloor off the Pacific Northwest coast experienced low-oxygen conditions in 2021. Data from 1950 to 1980 are from the World Ocean Database32, data from 2009–2018 are from the NOAA Groundfish survey, and data from 2021 are from this study.

Pacific Northwest coast suffers from low oxygen, study finds – “As we keep changing the climate, it’s going to become the norm. What’s pretty remarkable is that 50 percent of the continental shelf is going to be low oxygen.”

By Amanda Zhou 10 June 2024 (The Seattle Times) – About half of the water near the seafloor off the Pacific Northwest coast experienced low-oxygen conditions in 2021, according to a new study. And those hypoxic conditions, which are expected to become common with global warming, threaten the food web, the study found. The study […]

Billion-dollar disasters swept across the U.S. in Spring 2024

By Meredith Garofalo 13 June 2024 (Space.com) – Two severe weather events in May brought the number of billion-dollar disasters for the United States in 2024 up to nearly a dozen. The month began with a tornado outbreak from May 6 to May 10 that stretched across 23 states, going from South Dakota to Florida. […]

For shrinking Mississippi River towns, frequent floods worsen fortunes – “Everybody’s gone. This is a ghost town.”

By Michael Phillis, Jim Salter, and Camille Fassett 11 June 2024 WEST ALTON, Missouri (AP) – Devastating flooding, driven in part by climate change, is taking an especially damaging toll on communities that once thrived along the banks of America’s most storied river. Flooding has pushed people out of their homes near the Mississippi River at […]

How record-breaking Hurricane Beryl is a sign of a warming world – “What makes Beryl particularly notable is that it intensified the fastest from a tropical depression to a hurricane of any Atlantic hurricane in June or early July”

By Mark Poynting 4 July 2024 (BBC News) – Hurricane Beryl is wreaking havoc in parts of the Caribbean – and putting the role of climate change under the spotlight. With maximum sustained wind speeds of more than 160mph (257km/h), it became the earliest category five Atlantic hurricane in records going back around 100 years. […]

Climate change made killer heat wave in Mexico, Southwest U.S. even warmer and 35 times more likely – “The changes we have seen in the last 20 years, which feels like just yesterday, are so strong”

By Seth Borenstein 20 June 2024 WASHINGTON (AP) – Human-caused climate change dialed up the thermostat and turbocharged the odds of this month’s killer heat that has been baking the Southwestern United States, Mexico and Central America, a new flash study found. Sizzling daytime temperatures that triggered cases of heat stroke in parts of the United States were […]

Global number of extreme wildfires, 2003-2023. The analysis of satellite data showed the number of extreme fires had risen by more than 10 times in the past 20 years in temperate conifer forests, such as in the western U.S. and Mediterranean. Data: Cunningham, et al., Nature Ecology & Evolution, 2024. The most extreme wildfires are in the top 0.1 percent of fires by radiative power, identified from 21 years of satellite data.

Climate crisis driving exponential rise in most extreme wildfires – Frequency of extreme events doubled from 2003 to 2023 – “This is the effect of what we’re doing to the atmosphere, so action is urgent”

By Damian Carrington 24 June 2024 (The Guardian) – The climate crisis is driving an exponential rise in the most extreme wildfires in key regions around the world, research has revealed. The wildfires can cause catastrophic loss of human life, property and wildlife and cause billions of dollars of damage. Scientists say this is climate […]
