Costa Rica indigenous leader shot amid tensions over land rights – “The state has relinquished its duty and has abandoned these indigenous people to seek justice in the court system, which also fails them”

By Nina Lakhani 17 February 2020 (The Guardian) – An indigenous leader leading his people’s effort to reclaim ancestral land in Costa Rica has been wounded in a gun attack – the latest in a spate of targeted violence which has gone unpunished by authorities. Mainor Ortiz Delgado, 29, a leader of the Bribri indigenous […]

Graph of the Day: The Future of Ocean Acidification

18 December 2019 (NOAA) – New research by NOAA, the University of Maryland, and international partners published in Nature Scientific Reports shows that the changing chemistry of seawater has implications for continued greenhouse gas absorption. The ocean has been playing an important role in helping slow down global climate change by removing the greenhouse gas carbon dioxide […]

Storm Dennis, 2nd-strongest bomb cyclone on record in North Atlantic, wreaks havoc across UK, parts of France – Record 594 flood warnings and alerts issued in UK

17 February 2020 (AFP) – Britain on Monday began to clear up after Storm Dennis battered the country over the weekend, leading the government’s weather agency to issue a rare “danger to life” warning amid widespread flooding and high winds. Hundreds of flood warnings remained in place, including five “severe” warnings around the River Teme […]

Spatial cumulative extents of the Deepwater Horizon (DWH) oil spill. (A) Cumulative NESDIS anomaly daily composites integrated from 20 April 2010 to 21 July 2010. Daily fishing closures are marked with gray lines; the cumulative fishing closure area is marked with a thick dashed yellow line. The black star represents the location of the DWH blowout. (B) Cumulative value of daily average oil concentrations (ppb), integrated across the same time span as (A) and across water depths. Vertical depth layers are 0 to 1 m, 1 to 20 m, and in 20-m increments down to 2500 m. Sediment and water samples with higher-than-background concentration are marked in bright green and dark blue circles, respectively. Red crosses in (B) represent approximate locations of DWH-related oil detections reported in previous studies. Daily fishery closures are marked with black polygons; the cumulative fishery closure area is marked with a dashed thick polygon. AB, Apalachee Bay; DP, Deep Plume; EFS, East Florida Shelf; FK, Florida Keys; LC, Loop Current System; TXS, Texas Shores; WFS, West Florida Shelf. (C) Categorization of the modeled oil spill are as follows: (i) nontoxic, PAH concentrations above background level and smaller than 0.5 and 1 ppb at the surface (depth, 0 to 1 m) and in the water column (depth, >1 m), respectively; (ii) toxic-to-biota and invisible, PAH concentrations 0.5 to 17 ppb at the surface and above 1 ppb in the water column; and (iii) toxic and visible, PAH concentrations above 17 ppb. In (C), categories were computed according to maximal concentrations across time. (D) Duration of toxic concentrations across the domain. (E) LC50 of 12 experiments examining the photoinduced toxicity to blue crab (31), fiddler crab (33), mahi mahi (29, 30), red drum (32), and speckled sea trout (32) (for more details, see table S2). (F) The spatial extent of the toxic concentrations from (E); color codes in (F) are according to bar colors in (E), representing concentrations exceeding LC50. In (F), toxic PAH of 0.5 ppb was concentrations were considered for surface waters only (depth, 0 to 1 m). Graphic: Berenshtein, et al., 2020 / Science Advances

The toxic reach of the Deepwater Horizon oil spill was much larger and deadlier than previous estimates – “Large areas of the Gulf of Mexico were exposed to invisible and toxic oil that extended beyond the boundaries of the satellite footprint and the fishery closures”

By Darryl Fears 12 February 2020 (The Washington Post) – The spread of oil from the Deepwater Horizon disaster in the Gulf of Mexico was far worse than previously believed, new research has found. As the worst offshore oil spill in U.S. history approaches its 10th anniversary in April, a study by two University of Miami researchers […]

Hundreds of billions of locusts, fueled by conflict and climate change, are swarming East Africa – 400-fold increase in their numbers by June 2020 projected

By Madeleine Stone 14 February 2020 (National Geographic) – East Africa is in the midst of a crisis that sounds like something out of the Book of Exodus: A plague of locusts is spreading across the region, threatening the food supply of tens of millions. City-sized swarms of the dreaded pests are wreaking havoc as […]

15 years after the Kyoto Protocol went into force, the climate crisis is worse than ever – “If the U.S. had been in from the start, it would have been a different trajectory altogether”

By Rosie McCall 16 February 2020 (Newsweek) – The Kyoto Protocol went to force a full 15 years ago today—and yet, the climate crisis is more urgent than ever. On Sunday, 15 years will have passed since the Kyoto Protocol was ratified on February 16, 2005, which was eight years after it was negotiated back […]

January 2020 warmest on record in Europe – Earth matched its warmest January on record – “The lack of snow and the warmth is really unheard of. Monthly records were not just broken, they were shattered with large margins.”

By Matthew Cappucci 4 February 2020 (The Washington Post) – Europe just concluded its warmest January on record, coming on the heels of a toasty December and making the 2019-2020 winter season a contender for the warmest Europe has observed. Although the calendar has flipped to a new decade, there has been no slowing in […]
