Big Brazilian gold refiner delisted amid Amazon mining probe – “In Brazil, as in so many gold-producing countries, illegality enters into the supply chain very early on”

By Joshua Goodman and David Biller 5 October 2022 MIAMI (AP) – One of Brazil’s biggest gold refiners, which processes gold suspected of being mined illegally in the Amazon rainforest, has been stripped of an important industry seal of approval that global manufacturers from Apple to Tesla rely on to root out abuses in their […]

Five years after Hurricane Maria, Puerto Rico’s power grid is still costly and unreliable – Puerto Rico struggles to recover after Hurricane Fiona razed crops

By Fred Imbert 22 October 2022 (CNBC) – When Hurricane Fiona hit Puerto Rico in September, Felipe Pérez was ready. Pérez, the owner of local sandwich shop chain El Meson, equipped his stand-alone locations with power generators and water tanks in the event of a prolonged outage like the one after Hurricane Maria, the devastating […]

Discovery of “fingerprint” confirms alarming predictions of Greenland ice sheet melt – “How fast the ice sheets in Greenland and Antarctica will respond to warming is a really big unknown, and frankly a very scary unknown”

By Sarah Sloat 29 September 2022 (NBC News) – Scientists now have unambiguous proof that a phenomenon critical to predicting the impact of climate change exists. Researchers announced Thursday that they had detected the sea level “fingerprint” of the Greenland ice sheet melt, pinpointing the unique pattern of sea level change linked to the melting ice. It’s the […]

Climate change has come for the world’s largest greenhouse gas emitter – “There is nothing in world climatic history which is even minimally comparable to what is happening in China”

By Muizz Akhtar 29 September 2022 (Vox) – China just finished one of its most disastrous summers on record, with record-breaking heat, drought, and wildfires leading to water shortages even into the fall. More than 900 million people — or about 64 percent of China’s population — faced brutal heat waves alone, highlighting how much further the nation has to […]

(a) Ocean thermal forcing (shaded areas) at the ocean bottom or 1000 m (whichever is shallower) and annual submarine melt rate (filled squares) at Greenland’s marine-terminating glaciers. The black dotted line shows the 1,000 m isobath and delineates the extent of the continental shelf. The black dashed regions on the ice sheet delineate the hydrological catchments for three large example glaciers: Jakobshavn Isbrae (JI), Helheim (HH) and Kangerdlugssuaq (KG). The five ice sheet regions considered throughout the paper—south (SO), central-west (CW), northwest (NW), northeast (NE) and north (NO)—are delineated by the black ticks. Other labels are the Irminger Sea (Irm), Davis Strait (Dav) and Denmark Strait (Den). Bathymetry is from ref. 42 and ref. 43. (b) Subglacial discharge (x axis, note logarithmic scale) and ocean thermal forcing (y axis) for each marine-terminating glacier. The background shading shows the resulting submarine melt rate. Glaciers are coloured by their regional grouping. The larger squares and error bars show the median and interquartile range for each region, respectively. (c) Submarine melt rate versus grounding line depth by region with fitted linear trends (all significant at the 5% level) as dashed lines. All the results shown in these plots are annually averaged over 1979–2018. Graphic: Slater and Straneo, 2022 / Nature Geoscience

Warmer air and warmer water are combining to melt Greenland ice sheet – “This unfortunately adds to the overwhelming body of evidence showing the sensitivity of the Greenland ice sheet to climate change”

By Rachel Koning Beals 17 October 2022 (MarketWatch) – The Greenland ice sheet — one of the two most important glaciers of its kind on Earth — may be even more sensitive to the warming climate than scientists previously thought. The findings, published in the journal Nature Geoscience, shed fresh light on the forces driving ice […]

People walk through floodwaters after heavy rainfall in Hadeja, Nigeria, 19 September 2022. Officials in Nigeria say the death toll from this year's flooding has now risen to 603. Authorities have called the floods the country's worst in more than a decade, blaming the disaster on unusually heavy rainfall and the release of excess water from the Lagdo dam in neighboring Cameroon.

Millions of people at risk in Nigeria after worst floods in a decade – More than 1.3 million displaced – Cholera outbreak sickens 6,000 – 100,000 hectares of farmland underwater – Rains to continue through November – “This is a catastrophe indeed. All of these wrong things are happening at the same time.”

21 October 2022 (UN News) – More than 2.8 million people have been impacted by Nigeria’s worst floods in a decade, with 1.3 million displaced and hundreds of lives lost, said the UN chief on Friday, expressing his sadness at the devastation. Infrastructure and farmland have also been damaged, said the statement issued on behalf […]

Warming waters causing mass die-off of Alaska snow crabs – Total numbers down 84 percent since 2018 – “The cold-water habitat they need was virtually absent, which suggests that temperature is really the key culprit in this population decline”

20 October 2022 (CBS News) – Climate change is a prime suspect in a mass die-off of Alaska’s snow crabs, experts say, after the state took the unprecedented step of canceling their harvest this season to save the species. According to an annual survey of the Bering Sea floor carried out by the National Oceanic and Atmospheric Administration, […]

Percent change in ice volume for Swiss glaciers, 2001-2022. Melt rates in 2022 far exceeded the previous records from the hot summer of 2003. Glaciers in Switzerland lost around 3 cubic kilometres of ice in 2022, more than 6 percent of the remaining volume. By way of comparison, up to now, years with an ice loss of 2 percent have been described as “extreme”. The loss was particularly dramatic for small glaciers. Graphic: M.

2022 heat wave drove unprecedented melt of Swiss glaciers – “2022 was a disastrous year for Swiss glaciers: all ice melt records were smashed by the great dearth of snow in winter and continuous heat waves in summer”

By Jamey Keaten 28 September 2022 GENEVA (AP) – Switzerland’s glaciers are melting like never before, an academic study released Wednesday found, with their ice volume declining by 6% this year amid rising concerns about global warming and a summer heat wave that swept across Europe. The Swiss Academy of Sciences reported that the shrinkage […]

The Great Salt Lake is on the brink of collapse – “It’s terrifying”

By Carly Cassella 10 October 2022 (Science Alert) – Without urgent and major interventions, America’s Great Salt Lake could experience ecosystem collapse in the next few years. In a worst-case scenario, according to findings presented at the Geological Society of America’s 2022 Connects Conference in Colorado this past weekend, the world-famous body of salt-water has […]

A single, devastating California fire season wiped out years of efforts to cut emissions – “California’s wildfire CO2 emissions from 2020 are approximately two times higher than California’s total greenhouse gas reductions since 2003”

By Hayley Smith 20 October 2022 (Los Angeles Times) – A nearly two-decade effort by Californians to cut their emissions of planet-warming carbon dioxide may have been erased by a single, devastating year of wildfires, according to UCLA and University of Chicago researchers. The state’s record-breaking 2020 fire season, which saw more than 4 million acres […]
