University of Rochester researchers in Greenland drill for ice cores, which contain air bubbles with small quantities of ancient air trapped inside. By measuring the carbon-14 isotope in air from more than 200 years ago, the researchers found that scientists have been vastly overestimating the amount of fossil methane emitted by natural sources, and have therefore been underestimating the amount of methane humans are emitting into the atmosphere via fossil fuels.

Methane emitted via human fossil fuel use “vastly underestimated”

By Lindsey Valich 19 February 2020 (University of Rochester) – Methane is a powerful greenhouse gas and large contributor to global warming. Methane emissions to the atmosphere have increased by approximately 150 percent over the past three centuries, but it has been difficult for researchers to determine exactly where these emissions originate; heat-trapping gases like […]

Big freeze to grip Britain before weekend downpour hits – 178 flood alerts still in effect

By Dan Keane 6 March 2020 (The Sun) – Temperatures are set to drop by another -6C before another weekend of rain hits the country after weeks of heavy rainfall. Flooding alerts are still in place, and this weekend could bring more wet weather with heavy wind also expected. This will be the fifth weekend in a […]

The “blue acceleration”: Study shows humans’ surging incursions into the sea

By Grace Dungey 13 February 2020 (Mongabay) – Humanity has depended on the ocean for millennia. Today, however, the rush to the sea is occurring with unprecedented diversity and intensity, propelled by population growth and demand for diminishing terrestrial resources. A study published in January in the new journal One Earth analyzed 50 years of data on 18 kinds […]

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 […]

Obscure investment fund uses UK aid money to finance fossil fuel projects – “A farcical situation where the Government, on one hand, spends aid money to mitigate climate change, and on the other hand finances fossil fuels all over the world”

6 February 2020 (Global Witness) – We are at the beginning of a year of climate spin by the British Government. This year, the UK will host the 26th UN Climate Change Conference (COP26) in Glasgow. While the Government claims to be a ‘climate leader’, we reveal how a little-known investment group funded by the […]

Satellite view of tropospheric NO2 VCDs over the Permian basin for August 2018, seen from the Ozone Monitoring Instrument (OMI) and Tropospheric Monitoring Instrument (TROPOMI) aboard NASA and ESA satellites. OMI has a ground pixel size of 13 x 24 km2 and was gridded onto a 0.07 by 0.07 degrees latitude/longitude grid. TROPOMI has a footprint of 3.5 x 7 km2 and was averaged onto a 0.02 by 0.02 degrees latitude/longitude grid. The increased spatial resolution of the TROPOMI measurements is clearly visible. The red outline denotes the area used for the multivariate regression fits. Graphic: Dix, et al., 2020 / Geophysical Research Letters

Air pollution from oil and gas production sites visible from space – U.S. and European satellites help scientists measure nitrogen dioxide from drilling, production, and flaring

15 January 2020 (CIRES) – Oil and gas production has doubled in some parts of the United States in the last two years, and scientists can use satellites to see impacts of that trend: a significant increase in the release of the lung-irritating air pollutant nitrogen dioxide, for example, and a more-than-doubling of the amount […]

Japan panel recommends ocean release for contaminated Fukushima water

By Aaron Sheldrick 31 January 2020 TOKYO (Reuters) – A panel of experts advising Japan’s government on a disposal method for radioactive water from the destroyed Fukushima nuclear plant on Friday recommended releasing it into the ocean, a move likely to alarm neighboring countries. The panel under the industry ministry came to the conclusion after […]

By Ricardo Moraes 18 January 2020 XINGU INDIGENOUS PARK, Brazil (Reuters) – Leaders of native tribes in Brazil issued a rallying call to protect the Amazon rainforest and its indigenous people from what they called the “genocide, ethnocide and ecocide” planned by the country’s far-right President Jair Bolsonaro. A manifesto signed on Friday at the […]

Preliminary U.S. carbon emissions estimates for 2019 – Coming up short on climate targets

By Trevor Houser and Hannah Pitt 7 January 2020 (Rhodium Group) – After a sharp uptick in 2018, we estimate that US greenhouse gas (GHG) emissions fell by 2.1% last year based on preliminary energy and economic data. This decline was due almost entirely to a drop in coal consumption. Coal-fired power generation fell by […]

A cargo ship transits the Panama Canal on 21 April 2019 on its way to the Atlantic Ocean, while tree trunks that used to be submerged are exposed due to the low water levels of Gatún lake, Panama. An intense drought related to this year’s El Niño phenomenon has precipitously lowered the level of Panama’s Gatún Lake, forcing the country’s Canal Authority to impose draft limits this week on ships moving through the waterway’s recently expanded locks.

Water shortages dog Panama Canal, 20 years after its transfer – “It really has been the driest dry season we’ve had in the history of the canal”

31 December 2019 (DW) – The Panama Canal’s handover from the United States 20 years ago has been marked in Panama amid water supply worries. Managers say less rainfall due to climate change has depleted the inter-ocean conduit’s Gatun Lake. President Laurentino Cortizo hoisted a giant Panamanian flag outside Canal headquarters Tuesday as its operators […]
