Icebound The climate-change secrets of 19th century ship’s logs

Reuters – “An eccentric group of citizen-scientists called Old Weather has transcribed millions of observations from long-forgotten logbooks of ships, many from the great era of Arctic exploration. As the polar regions grow ever warmer, the volunteers have amassed a rich repository of climate data in a 21st century rescue mission…

Meteorologists have long recorded the weather at land-based stations. But nearly three-quarters of the planet is covered by water, and that’s where most weather takes place. Thousands of ships have criss-crossed the oceans, noting the weather in handwritten logbooks that for decades sat forgotten in bookshelves and basements. In a sometimes-obsessive quest, thousands of Old Weather volunteers have extracted millions of observations about barometric pressure, wind speed, air temperature and ice from the old logbooks. These are fed into a huge dataset at the U.S. National Oceanic and Atmospheric Administration, creating what NOAA calls “a dauntingly complex, high-resolution, four-dimensional reconstruction of the global climate that estimates what the weather was for every day back to 1836.”

Latest Arctic Report Card – melting permafrost emitting billions of tons of carbon into air

“NOAA’s 14th Arctic Report Card recounts the numerous ways that climate change continued to disrupt the polar region during 2019, with near-record high air and ocean temperatures, a massive melt of the Greenland ice sheet, record low sea-ice extents, and major shifts in the distribution of commercially valuable marine species.  The Arctic Report Card is… Continue Reading

Study finds North American birds getting smaller

Reuters: “Since 1978, researchers have scooped up and measured tens of thousands of birds that died after crashing into buildings in Chicago during spring and fall migrations. Their work has documented what might be called the incredible shrinking bird. A study published on Wednesday involving 70,716 birds killed from 1978 through 2016 in such collisions… Continue Reading
