Plastic Reaches Antarctica

Scientists have found for the first time evidence that plastic has entered the food chain in the Antarctic. Researchers write in the journal Biology Letters that bits of polystyrene were discovered in the guts of tiny organisms known as springtails, living in the soil not covered by ice on King George Island, off the tip of the Antarctic Peninsula.

Extensive scientific research, along with an airport, military facilities and visiting tourists, make it what the researchers call one of the most contaminated regions of the Antarctic. The authors of the report said they believe the springtails inadvertently consumed the plastic fragments while grazing on their usual food.

Global Warming

Six Month Deadline

The Paris-based International Energy Agency has warned that world leaders have only six months to take measures to control carbon emissions, before a post-lockdown recovery brings a surge in the greenhouse gases that may be impossible to curb. The organization cautions that without immediate action, reaching the targets to address global warming will not be possible.

“This year is the last time we have, if we are not to see a carbon rebound,” said Fatih Birol, executive director of the International Energy Agency. He told The Guardian governments must design economic recovery packages that promote shifts away from carbon-based fuels.

Roundup of Global Volcanic Activity – Ongoing Activity for the Week 17 June 2020 – 23 June 2020

Aira | Kyushu (Japan) : JMA reported that very small eruptive events were recorded at Minamidake Crater (at Aira Caldera’s Sakurajima volcano) during 19-22 June. The Alert Level remained at 3 (on a 5-level scale).

Cleveland | Chuginadak Island (USA) : AVO reported that no additional volcanic activity was detected at Cleveland after the short-lived explosion recorded on 1 June. The Volcano Alert Level was lowered to Advisory and the Aviation colour Code was lowered to Yellow.

Copahue | Central Chile-Argentina border : On 17 June OVDAS-SERNAGEOMIN reported increased activity at Copahue during the previous days, characterized by low-altitude gas emissions containing particulate matter. A period of increased seismicity was recorded in the afternoon on 16 June accompanied by crater incandescence and emissions visible in webcam images. The report noted that very-long-period earthquakes had been recorded in previous months, and a series of volcano-related seismic events were detected in an area SSW of the volcano on 20 March. Additionally, satellite images showed a reduction in the size of the crater lake. These recent changes coupled with increased seismicity prompted SERNAGEOMIN to raise the Alert Level to Yellow (second lowest level on a four-colour scale) and restrict access to an area within 1 km of El Agrio Crater. ONEMI raised a Yellow Alert (the middle level on a three-colour scale) for residents of the Alto Biobío municipality.
