Global Warming

The warming Arctic Ocean is bringing more snowfall to Siberia

Global warming has increased the evaporation and retreat of sea ice in the Arctic Ocean. The climate change-induced impacts in the Arctic Ocean could be responsible for an increase in snow cover in Siberia, a new study has suggested.

Enhanced evaporation deposits more moisture in the Arctic atmosphere, which makes its journey towards the western parts of Siberia where the moisture is deposited as snow.

It was also found that increased snow cover in western Russia increased the risk of summer heat waves in Europe and Northeast Asia. More research needs to be done to fully understand the interplay for global weather effects consequent on a rapidly warming Artic.

Wildfires

Wildfires – Europe

Over 20 wildfires raged across Portugal and several burned in western Spain yesterday, menacing villages and disrupting tourists’ holidays amid a heatwave that meteorologists expect to push temperatures into the high 40s Celsius.

In Spain’s western region of Extremadura bordering Portugal firefighters evacuated a few hundred villagers overnight as a precaution and continued to battle a blaze that on Tuesday swept into Salamanca province in the region of Castile and Leon.

In France too, about 800 firefighters, supported by six water-bomber aircraft, were battling two wildfires in the southwest, which have already prompted the evacuation of thousands of campers. About 2 700 hectares were burned.

Volcanos

Roundup of Global Volcanic Activity – Ongoing Activity for the week 16 November – 22 November 2022

Aira – Kyushu (Japan) : JMA reported ongoing eruptive activity at Minamidake Crater (at Aira Caldera’s Sakurajima volcano) and nighttime crater incandescence during 14-21 November. Sulfur dioxide emissions were slightly high on 14 November at 1,100 tons per day. Six eruptive events and four explosions (during 15-16 and 20-21 November) produced volcanic plumes that rose as high as 2.2 km above the crater rim and ejected large blocks as far as 900 m from the vent.

Alaid – Kuril Islands (Russia) : Activity has been gradually decreasing since the last ash plume was recorded on 26 October. A thermal anomaly continued to periodically be identified in satellite images when weather conditions permitted views, though the temperature of the thermal anomaly began decreasing on 29 October.

Ebeko – Paramushir Island (Russia) : KVERT reported that moderate activity at Ebeko was ongoing during 10-17 November. According to volcanologists in Severo-Kurilsk (Paramushir Island, about 7 km E) explosions during 12-13 and 16 November generated ash plumes that rose to 2.6 km (8,500 ft) a.s.l. and drifted in eastern directions. Ash fell in Severo-Kurilsk on 16 November. A thermal anomaly was identified in satellite images on 16 November; weather clouds prevented satellite views on the other days of the week.

Great Sitkin – Andreanof Islands (USA) : AVO reported that slow lava effusion continued at Great Sitkin during 15-22 November and the flow field continued to grow. Flow lobes extended about 600 m E of the vent and about 430 m S. Seismicity was low, with the occasional detection of low-frequency earthquakes. Satellite and webcam images were often cloudy through the week.

Karymsky – Eastern Kamchatka (Russia) : KVERT reported that a thermal anomaly at Karymsky was identified in satellite images on 13 and 15-17 November. Gas-and-steam emissions persisted.

Kerinci – Central Sumatra : PVMBG reported that brown ash plumes from Kerinci, often dense, rose as high as 150 m above the summit and drifted NE, E, and SE during 16-18 and 20-21 November. Weather clouds prevented visual observations during 18-20 November.

Kilauea – Hawaiian Islands (USA) : HVO reported that lava continued to effuse from a vent in the lower W wall of Kilauea’s Halema`uma`u Crater during 16-22 November entering the lava lake and flowing onto the crater floor. The active part of the lake remained at a steady level all week.

Manam – Northeast of New Guinea : The Darwin VAAC reported that on 20 November ash plumes from Manam rose to 1.8 km (6,000 ft) and drifted NW based on satellite images.

Pavlof – Alaska Peninsula, Alaska: AVO reported that a minor eruption at a vent on Pavlof’s upper E flank was ongoing during 16-22 November and nearly continuous seismic tremor was recorded. Almost daily elevated surface temperatures were identified in satellite images; weather clouds prevented views during 21-22 November. Webcam images showed occasional minor steaming and minor ash emissions in addition to a recent mass flow and ash deposits on the upper to lower flanks visible during 15-16 November, and incandescence at the vent during 16-17 November possibly associated with lava spattering or fountaining.

Semeru – Eastern Java : PVMBG reported that the eruption at Semeru continued during 16-22 November. White gas-and-steam plumes rose 100-200 m above the summit and drifted in various directions during 16-17 November. Emissions were not visible during 18-20 November, though weather conditions sometimes prevented visual observations. At 0608 on 21 November a white-to-gray ash plume rose around 400 m and drifted E. On 22 November white-to-gray ash plumes rose 300 m and drifted S at 0405, 600 m at 0503, and 800 m at 1541.

Semisopochnoi – Aleutian Islands (USA) : AVO reported ongoing low-level seismicity at Semisopochnoi characterized by intermittent seismic tremor and occasional low-frequency earthquakes during 16-22 November. Satellite and webcam views were mostly obscured by weather clouds, though during clear views continuous gas-and-steam emissions from the N crater of Mount Cerberus were visible.

Sheveluch – Central Kamchatka (Russia) : KVERT reported that the ongoing eruption at Sheveluch during 11-17 November was generally characterized by explosions, hot avalanches, lava-dome extrusion, and strong fumarolic activity. A daily thermal anomaly was identified in satellite images. Collapses generated hot avalanches and ash plumes that drifted 85 km ENE during 13-14, and 16-17 November.

Suwanosejima – Ryukyu Islands (Japan) : JMA reported that the eruption at Suwanosejima’s Ontake Crater continued during 14-21 November and crater incandescence was visible nightly. Eruption plumes generally rose 600 m above the crater rim and blended into weather clouds. An explosion at 0251 on 15 November ejected blocks 500 m from the vent and produced an eruption plume that rose 2.3 km above the crater rim and drifted SE.

Saudi Arabia – Two people have died in floods that swept across Saudi Arabia’s coastal city of Jeddah on Thursday due to record rain levels. The floods have also caused flight delays at King Abdulaziz International Airport, school closures and blocked the road to Mecca, Islam’s holiest city. According to Saudi Arabia’s National Center for Meteorology, the rainfall in Jeddah’s southern area between 8am and 2pm on Thursday, which stood at 179 millimeters, was the “highest” ever recorded.

Portugal – Authorities in the municipality of Esposende in Braga District of northern Portugal report that 2 people have died after a landslide following heavy rainfall. A landslide and large rocks destroyed part of a single-family home in Palmeira de Faro in Esposende early on 23 November 2022. Two people died and 4 people were rescued unharmed.

Wildlife

Extinct Bird Rediscovered

An exotic bird thought to have gone extinct 140 years ago has been “rediscovered” by researchers on a tiny island off Papua New Guinea. The black-naped pheasant pigeon was spotted in images from remote cameras on Fergusson Island.

“It is the kind of moment you dream about your entire life as a conservationist and birdwatcher,” said expedition co-lead John Mittermeier. The team initially had help from one local who reported seeing the pheasant-pigeon several times in an area with steep ridges and valleys, and described hearing the bird’s distinctive calls.

Shark Protection

Representatives attending the world’s largest wildlife summit have voted for the first time to regulate the hunting of sharks, which kills millions of the fish each year to meet the huge demand for shark fin soup.

The 186-nation Convention on International Trade in Endangered Species of Wild Fauna and Flora, or CITES, signed an agreement to regulate the commercial fishing of 54 shark species, including tiger, bull and blue sharks, which are the most targeted for the fin trade.

Environment

Reproduction in Crisis

Drops in sperm counts of more than 60% in North American, European and Australian men between 1973 and 2018 means humans could face a reproductive crisis.

Writing in the journal Human Reproduction Update, researchers warn the decline is accelerating and that declines were also occurring in Central and South America, Africa and Asia. It’s unclear what might be behind the apparent trend, but exposure to endocrine-disrupting chemicals or other environmental factors could be factors.
