Global Warming

Warming Arctic

EU satellites recorded ground temperatures above 118 degrees Fahrenheit in Arctic Siberia on June 20 — the 2021 summer solstice and summer is just heating up.

The heat wave baking Siberia on June 20 saw ground temperatures reach 118 degrees Fahrenheit in an area that often records the world’s coldest temperatures during winter.

The reading near Verkhoyansk was measured by Europe’s Copernicus Sentinel satellite system.

While the air temperature recorded in Verkhoyansk was only 86 degrees that day, many Siberian temperature records were broken. The scorching ground heat was also observed across a wide area of Siberia in a development that does not bode well for Russia’s rapidly melting permafrost and the potent greenhouse gases the melt is releasing.


Conservation Backfires

Conservationists in Tasmania may be ruing the decision to introduce endangered Tasmanian devils to a small island, after a new survey revealed that the alien invaders have wiped out the entire colony of little penguins living there.

Tasmanian devils (Sarcophilus harrisii), the world’s largest carnivorous marsupials, were introduced to Maria Island — a 45-square-mile (116 square kilometers) island east of Tasmania in 2012. The government hoped to create a new devil population to prevent the species from being wiped out by a deadly disease that has decimated their numbers in Tasmania.

However, the introduction of one species has meant the end of another: The new DPIPWE survey showed that the introduction of devils to the island wiped out 3,000 breeding pairs of little penguins (Eudyptula minor) living on the island.


Mice Overrun Prison

The vast mouse plague that has ravaged Australian agriculture and wildlife for more than a year has also infested a New South Wales prison so badly that the entire prison population and staff had to be evacuated to other facilities.

The rodents gnawed through wiring and ceiling panels, and littered the prison with their dead carcasses. “The mice start decaying, and then the next problem is mites, and we just don’t want to expose staff and prisoners to anything that could cause harm to their health,” said Peter Severin, commissioner of the state’s corrective services department.


Global Temperature Extremes

The week’s hottest temperature was 125 degrees Fahrenheit (51.7 degrees Celsius) in Death Valley, California.

The week’s coldest temperature was minus 107.0 degrees Fahrenheit (minus 77.2 degrees Celsius) at Vostok, Antarctica.

Temperatures were tabulated from the more than 10,000 worldwide synoptic weather stations. The United Nations World Meteorological Organization sets the standards for weather observations, and provides a global telecommunications circuit for data distribution.

Roundup of Global Volcanic Activity – Ongoing Activity for the Week 16 June – 22 June 2021

Aira – Kyushu (Japan) : JMA reported that during 14-21 June incandescence from Minamidake Crater (at Aira Caldera’s Sakurajima volcano) was visible nightly. The sulfur dioxide emission rate was elevated at 1,400 tons per day on 15 June. The Alert Level remained at 3 (on a 5-level scale), and residents were warned to stay 2 km away from the crater.

Ebeko – Paramushir Island (Russia) : According to volcanologists in Severo-Kurilsk (Paramushir Island), about 7 km E of Ebeko, explosions during 11-18 June produced ash plumes that rose as high as 3.5 km (11,500 ft) a.s.l. and drifted in multiple directions. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Etna – Sicily (Italy) : INGV reported that there were several episodes of lava fountaining at Etna’s Southeast Crater (SEC) during 14-23 June, and additional periods of Strombolian activity and ash emissions. The lava fountaining episodes were recorded during 1332-1450 on 16 June, 2220 on 18 June to 0210 on 19 June, 2040-2215 on 19 June, 1131 on 20 June to 0214 on 21 June, overnight during 21-22 June, and in the early hours of 22 and 23 June. Each episode began with Strombolian activity which was followed by lava fountaining and crater overflows sending lava down the flanks. Ash plumes that rose as high as 4.7 km above the summit and sometimes caused ashfall in areas downwind. Lava flows on 16 June descended the SW and SE flanks, and those produced on 21 June traveled about 1 km SW, towards Monte Frumento Supino, and stopped at 2,900 m elevation. The lava fountains on 21 June were notably tall.

Fuego – Guatemala, : INSIVUMEH reported that on 15 June lahars descended the Las Lajas and El Jute drainages on Fuego’s SE flank, carrying tree branches and blocks as large as 1.5 m in diameter. During 16-22 June there were 4-15 explosions per hour, generating ash plumes as high as 1.1 km above the crater rim. Daily shock waves rattled buildings in towns around the volcano, and within 15 km of the S and SW flanks during 20-21 June. Ashfall was reported almost daily in several areas downwind, including Panimaché I and II (8 km SW), Santa Sofía (12 km SW), Sangre de Cristo (8 km WSW), and San Pedro Yepocapa (8 km NW). Block avalanches descended the Ceniza (SSW), Seca (W), Trinidad (S), Taniluyá (SW), Las Lajas (SE), and Honda drainages, often reaching vegetated areas. Explosions ejected incandescent material 100-350 m above the summit each day.

Ibu – Halmahera (Indonesia) PVMBG reported that during 15-21 June gray-and-white ash plumes from Ibu rose 200-800 m above the summit and drifted N, E, and S. As many as 63 eruptive events per day were recorded during 18-20 June. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to stay at least 2 km away from the active crater and 3.5 km away on the N side.

Kadovar – Papua New Guinea : Based on satellite and wind model data, the Darwin VAAC reported that on 19 June ash plumes from Kadovar rose to an altitude of 1.5 km (5,000 ft) a.s.l. and drifted W.

Lewotolok – Lembata Island (Indonesia) : PVMBG reported that white-and-gray plumes from Lewotolok rose as high as 1 km and drifted W and NW daily during 16-22 June. Incandescent material was ejected as high as 500 m above the summit and 300-500 m away from the vent in multiple directions almost daily. The Alert Level remained at 3 (on a scale of 1-4) and the public was warned to stay 3 km away from the summit crater.

Merapi – Central Java (Indonesia) : BPPTKG reported that the lava dome just below Merapi’s SW rim and the lava dome in the summit crater both continued to be active during 11-17 June. The SW rim lava-dome volume was an estimated 1.39 million cubic meters by 17 June, with a growth rate of 11,300 cubic meters per day, and continued to shed material down the flank. A total of 19 pyroclastic flows traveled a maximum of 2 km down the SW flank and 1 km SE. Incandescent avalanches, recorded 100 times, traveled as far as 2 km down the SW flank and eight times went 1 km SE. The summit lava dome grew taller by 1 m. At 0350 on 20 June a pyroclastic flow traveled 2.5 km down the SW flank. The Alert Level remained at 3 (on a scale of 1-4), and the public was warned to stay 5 km away from the summit.

Pacaya – Guatemala : INSIVUMEH reported that during 15-22 June white gas plumes rose as high as 600 m above Pacaya’s Mackenney Crater and drifted as far as 5 km NW, W, and SW. Some weak explosions were recorded by the seismic network during 17-18 June.

Sabancaya – Peru : Instituto Geofísico del Perú (IGP) reported a daily average of 80 explosions at Sabancaya during 14-20 June. Gas-and-ash plumes rose as high as 2.3 km above the summit and drifted S, SE, E, and NE. Seven thermal anomalies originating from the lava dome in the summit crater were identified in satellite data. Minor inflation continued to be detected near Hualca Hualca (4 km N). The Alert Level remained at Orange (the second highest level on a four-colour scale) and the public were warned to stay outside of a 12-km radius.

Sangay – Ecuador IG reported a high level of activity at Sangay during 15-22 June. Weather clouds and rain often prevented visual and webcam observations of the volcano; almost daily lahars were detected by the seismic network. Ash plumes were identified in satellite images by the Washington VAAC ash plumes almost daily, rising as high as 1.2 km above the volcano and drifting W and SW. Thermal anomalies continued to be often visible in satellite data.

Semeru – Eastern Java (Indonesia) : PVMBG reported that Semeru continued to erupt during 16-22 June. Inclement weather often prevented visual observations, through gray-and-white plumes were visible on 17 and 20 June rising 400-600 m above the summit and drifting S and N. The Alert Level remained at 2 (on a scale of 1-4), with a general exclusion zone of 1 km and extensions to 5 km in the SSE sector.

Semisopochnoi – Aleutian Islands (USA) : AVO lowered Semisopochnoi’s Aviation colour Code to Yellow and the Volcano Alert Level to Advisory on 16 June, reporting that no explosions or ash emissions had been detected since 30 May and seismicity was relatively low. The report noted that elevated surface temperatures and sulfur dioxide emissions were recorded on several occasions during the previous few weeks, indicating continued volcanic unrest.

Sheveluch – Central Kamchatka (Russia) : KVERT reported that a thermal anomaly over Sheveluch was identified in satellite images during 10-18 June. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Suwanosejima – Ryukyu Islands (Japan) : JMA reported that 15 explosions at Suwanosejima’s Ontake Crater produced eruption plumes that rose as high as 1.8 km above the crater rim during 11-18 June. Large volcanic bombs were ejected 500 m from the crater. Ashfall was reported in Toshima village (4 km SSW). Crater incandescence was visible nightly. The Alert Level remained at 2 and the public was warned to stay 1 km away from the crater.

Taal – Luzon (Philippines) : PHIVOLCS reported that unrest at Taal continued during 15-22 June. Low-level background tremor that had begun at 0905 on 8 April continued. One volcanic earthquake was recorded during 15-16 June, and 92 were recorded during 18-19 June along with 10 low-frequency volcanic earthquakes. Between two and 82 episodes of volcanic tremor were detected during 18-19, 19-20, and 21-22 June, with periods lasting as short as one minute to as long as four hours. Almost daily upwelling of hot volcanic fluids in the crater lake produced steam plumes that rose as high as 1.2 km and drifted in multiple directions. Sulfur dioxide emissions averaged 3,007-5,604 tonnes/day. PHIVOLCS noted the continuing state of elevated unrest, reminding the public that the Alert Level for Taal remained at 2 (on a scale of 0-5). PHIVOLCS strongly recommended no entry onto the island, and access to the Main Crater, Daang Kastila fissure (along the walking trail), and boating on Taal Lake was strictly prohibited.
