Microplastics are a million times more abundant in the ocean than previously thought

By MacKenzie Elmer 3 December 2019 (UCSD News Center) – Nothing seems safe from plastic contamination. It is pulled from the nostrils of sea turtles, found in Antarctic waters and buried in the fossil record. But a new study by researchers from Scripps Institution of Oceanography at the University of California San Diego suggests there could […]

Carbon dioxide emissions from natural gas, petroleum, coal, and land use changes, 1998-2017, in gigatons of CO2 per year. Graphic: GCP

Global carbon emissions growth slows, but still hits record high in 2019 – “Emissions cuts in wealthier nations must outpace increases in poorer countries where access to energy is still needed”

By Rob Jordan 3 December 2019 (Stanford News Service) – The runaway train that is climate change is about to blow past another milestone: global fossil-fuel carbon dioxide emissions will reach yet another record high. Driven by rising natural gas and oil consumption, levels of CO2 are expected to hit 37 billion metric tons this […]

Russian scientists find giant methane fountains in Arctic Ocean – “This is the most powerful seep I have ever been able to observe”

By Alec Luhn 8 October 2019 MOSCOW (The Telegraph) – Russian scientists in the Arctic Ocean said they have discovered the most powerful methane gas fountain ever recorded, highlighting the danger of this greenhouse gas accelerating climate change or causing an oil or gas spill as it erupts from thawing permafrost. A research expedition from […]

The Ocean Cleanup project successfully catches plastic in the great pacific garbage patch

2 October 2019 (The Ocean Cleanup) — Today, we announced that System 001/B is successfully capturing and collecting plastic debris. After one year of testing, we have succeeded in developing a self-contained system in the Great Pacific Garbage Patch that is using the natural forces of the ocean to passively catch and concentrate plastic, thereby […]

When the “Goliat” came on stream later in 2016, it was the world’s northernmost producing offshore oil field. Photo: Fredrik Refvem / Stavanger Aftenblad

Cowboy Nation: Norway’s Wild West fantasy – “It’s your misfortune and none of my own”

By Henrik Olav Mathiesen 11 September 2019 (The Dark Mountain Project) – Equinor is the publicly owned Norwegian company firmly intent upon wreaking havoc on the world for as long as possible. Off our own shores – and far beyond. In 2017, the company won the bid for two licences to drill offshore in the […]

Dangerous new hot zones are spreading around the world

By Chris Mooney and John Muyskens 11 September 2019 LA CORONILLA, Uruguay (The Washington Post) – The day the yellow clams turned black is seared in Ramón Agüero’s memory. It was the summer of 1994. A few days earlier, he had collected a generous haul, 20 buckets of the thin-shelled, cold-water clams, which burrow a […]

Hawaii was surrounded by waters with warmer-than-average sea surface temperatures on 9 September 2019. Departures from the seasonal norm are shown in degrees Celsius. On this date, Lihue, Kauai observed its 17th consecutive day of a daily record high temperature being set or tied. This is likely the longest such stretch for any official weather station with a long period of record (more than 50 years) at any site in the U.S. climate database. Graphic: Tropical Tidbits

Hawaii’s warmest summer on record and Alaska’s second warmest in 2019

By Christopher C. Burt 10 September 2019 (Weather Underground) – Although 2800 miles of open ocean separate them, both Anchorage, Alaska and Honolulu, Hawaii experienced their warmest climatological summers (June-August) on record this year. It appears that this was Alaska’s second warmest summer (following that of 2004) but it is likely that it was Hawaii’s […]

Landsat 8 images from 21 July 2018 (left) and 16 September 2018 (right) illustrating the Taku Glacier transient snowline. The 21 July 2018 snowline is at 975 m and the 16 September 2018 snowline is at 1400 m. Average end-of-summer snowline is 975 m; the 2018 end-of-summer snowline was the highest observed in the 73-year record. Graphic: AMS

State of the Climate in 2018: 2018 was the fourth-hottest year on record, behind 2016, 2015, and 2017

12 August 2019 (NCEI) – A new State of the Climate report [pdf] confirmed that 2018 was the fourth warmest year in records dating to the mid-1800s. Last year was the fourth warmest year on record despite La Niña conditions early in the year and the lack of a short-term warming El Niño influence until […]

Remote sensing imagery of discolored water and algal blooms in the Florida Bay and the Florida Keys region between 1992 and 2013 showing connectivity of the mainland and the lower Florida Keys, all outlined in red. (a) Landsat true color image on 29 May 1992 shows turbid water in western Florida Bay and discolored, black water in central Florida Bay that extends southward to the lower Florida Keys; (b) AVHRR reflectance image on 12 March 1996 shows high turbidity from the Shark River Slough plume extending beyond the lower Florida Keys towards Dry Tortugas; (c, d) VIIRS chlorophyll a anomaly images show phytoplankton blooms off Shark River Slough reaching the lower Florida Keys that were partially composed of the cyanobacterium, Synechococcus, on (c) 24 November 2013 and (d) 27 January 2014.

Nutrient loading lowers resistance to thermal stress in Florida Keys corals – “These data make clear that this is not an ‘either temperature or nutrients’ situation, but rather a ‘both/and’ combination of multiple stressors”

By Gisele Galoustian 15 July 2019 (FAU) – Coral reefs are considered one of the most threatened ecosystems on the planet and are dying at alarming rates around the world. Scientists attribute coral bleaching and ultimately massive coral death to a number of environmental stressors, in particular, warming water temperatures due to climate change. A […]

Leaving microbes out of climate change conversation has major consequences, experts warn – “Climate change is literally starving ocean life”

By Ivy Shih 19 June 2019 (UNSW) – An international group of leading microbiologists have issued a warning, saying that not including microbes – the support system of the biosphere – in the climate change equation will have major negative flow-on effects. More than 30 microbiologists from 9 countries have issued a warning to humanity […]
