Human-caused sea level rise drives 21st-century worldwide water level extremes

By -
By Daniel M. Gilford, et al, Science. 

Abstract: The rate and impacts of sea level rise vary considerably around the world, but the contribution of human-caused climate change to increases in local and regional flood risks has not yet been systematically explored. ...we quantify human-caused climate change’s contributions to sea level rise at worldwide locations using budget-based and semiempirical model methods. Results show that human-caused sea level rise is quantifiable at 97% of 519 tide gauge sites and is responsible for 58% (44 to 65%) of the observed daily extreme water level exceedances over 2000–2018. On average, human-caused sea level rise has caused a near-tripling in the number of days with attributable exceedances since the 1970s....

New Lessons from Old Ice: How We Understand Past (and Future) Heating

By -
By Mariana Mastache-Maldonado , Eos/AGU.  Excerpt: Fragments of blue ice up to 6 million years old—the oldest ever found—offer key insights into Earth’s warming cycles. Researchers are using these ancient data to refine models of our future climate. ...In Antarctica...rare formations known as blue ice areas may offer a distinct look into that deep past. These areas, which make up barely 1% of the continent, form where strong winds strip away surface snow. ...The Allan Hills region, situated on the edge of the East Antarctic Ice Sheet.... Here researchers have discovered ice up to 6 million years old—the oldest yet found. Their  study  of the ice, published in  Proceedings of the National Academy of Sciences of the United States of America , revealed that parts of it formed during periods far warmer than today—times when sea levels were higher and open forests and grasslands covered much of the planet. ...studying the atmospheric remnants trapped in blue ice, the rese...

E.P.A. Delays Requirements to Cut Methane, a Potent Greenhouse Gas

By -
By Lisa Friedman  and  Maxine Joselow , The New York Times.  Excerpt: The Environmental Protection Agency announced on Wednesday that it would delay a requirement that the oil and gas industry limit emissions of methane, a powerful planet-warming gas. Under the requirement, which dates to the Biden administration, oil and gas companies were supposed to start this year reducing the amount of methane they release into the atmosphere. Instead, the Trump administration is giving them until January 2027 and is considering repealing the measure altogether. The move dealt a blow to any remaining effort by the United States to slow Earth’s dangerous warming. It came after the Trump administration  boycotted the United Nations climate summit  this month, the first time that the United States was not present since the annual meetings began 30 years ago....  Full article at https://www.nytimes.com/2025/11/26/climate/epa-delays-methane-oil-gas.html .

Medieval volcano may have indirectly sparked Europe’s Black Death

By -
By Andrew Curry , Science.  Excerpt: The Black Death is the single most deadly documented pandemic in human history. In 1347 C.E., it spread from a few Italian port cities to nearly every corner of Europe, killing tens of millions of people within a decade and eliminating more than half the continent’s population. In a paper published today in  Communications Earth & Environment , researchers argue that cool weather  spurred by previously unidentified volcanic eruptions  set into motion a deadly chain of events. ...The authors of the new paper suggest volcanic eruptions a few years before the plague’s rapid spread played a role, by pushing plumes of sulfur high into the atmosphere that cooled parts of Europe and caused harvests to fail around the Mediterranean. These failures, in turn, forced Italian cities to import large quantities of grain from the plague-wracked Black Sea region—along with infected fleas, capable of subsisting on grain dust in the cargo holds...
