Germany – Germany has been inundated by heavy rain and thunderstorms. Some parts of the capital, Berlin, have been left under water. Traffic slowed to a halt in some parts of the city due to the torrential downpour. The storms are expected to continue over the weekend, particularly in the east of the country. Germany has endured more than its fair share of bad weather recently. A storm in the north of the country claimed the lives of two people last week.

Mexico – The rainy season has hit Mexico City where a deluge caused havoc yesterday. Heavy rains lashed the city beginning in the late afternoon, causing flash flooding that stranded motorists in their submerged vehicles, forced the closure of key transportation infrastructure and flooded people’s homes. Up to 70 millimeters of rain fell on some parts of the city.

Large-scale study shows neonic pesticides harm bees

96610350 c0128426 honey bee hive spl

The most extensive study to date on neonicotinoid pesticides concludes that they harm both honeybees and wild bees. Researchers said that exposure to the chemicals left honeybee hives less likely to survive over winter, while bumblebees and solitary bees produced fewer queens.

The study spanned 2,000 hectares across the UK, Germany and Hungary and was set up to establish the “real-world” impacts of the pesticides.

Neonicotinoids were placed under a temporary ban in Europe in 2013 after concerns about their impact on bees. The European Commission told the BBC that it intends to put forward a new proposal to further restrict the use of the chemicals.

Prof Richard Pywell, from the Centre for Ecology and Hydrology in Oxfordshire, who carried out the research, told BBC News: “Our findings are a cause for serious concern. “We’ve shown for the first time negative effects of neonicotinoid-coated seed dressings on honeybees and we’ve also shown similar negative effects on wild bees. “This is important because many crops globally are insect pollinated and without pollinators we would struggle to produce some foods.”

However, Bayer, a major producer of neonicotinoids which part-funded the study, said the findings were inconclusive and that it remained convinced the pesticides were not bad for bees.

A second study published in the journal Science looked at commercial corn-growing areas of Canada. The scientists found that worker bees exposed to neonicotinoids had lower life expectancies and their colonies were more likely to permanently lose queens.

African Ark

Thousands of wild animals are being moved across parts of Africa in an attempt to restore their populations in Mozambique, where a bloody 15-year civil war nearly wiped them out.

Neighboring Zimbabwe is donating and transporting 50 elephants, 100 giraffes, 200 zebras and 200 water buffaloes to Mozambique’s Zinave National Park in one of Africa’s largest ever wildlife transfers.

In total, about 7,500 wild animals from Zimbabwe, South Africa and elsewhere in Mozambique will be relocated during the next three years to help Zinave officials restore the park’s diversity.

Gelatinous Invasion

Scientists are baffled by the mounting invasion of jellylike organisms that are clogging fishing gear from California to British Columbia this year.

The glowing, tubular pyrosome clusters are typically found in the tropics far from shore, but they have spread northward right along the Pacific Coast in recent years.

There are now reports of them as far north as Sitka, Alaska.

Some West Coast fishermen say there are now so many of the “sea pickles” in the water that it is impossible to catch anything else.

Environment

Global Temperature Extremes

The week’s hottest temperature was 127.0 degrees Fahrenheit (52.8 degrees Celsius) in Death Valley, California.

The week’s coldest temperature was minus 108.0 degrees Fahrenheit (minus 77.8 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.

Wildfires

Wildfires – USA

Gusty winds and soaring temperatures have spread wildfires in numerous states across the Southwest, forcing hundreds of residents from their homes.

The National Interagency Fire Center said Thursday that six states including Arizona, California and New Mexico are dealing with “multiple large fires,” with more than 8,000 firefighters and support workers battling the blazes. The Interagency has raised the danger level, which helps mobilize additional resources.

In Central Arizona’s Yavapai County, the Goodwin Fire — named for the area near where the fire started — has engulfed more than 20,000 acres of mostly scrubland known locally as chaparral. The fire is also threatening several residential communities, spurring the evacuation of at least 1,500 people.

Officials say lightning sparked the Frye Fire earlier this month. It continues to burn around 40,000 acres of rugged terrain in Arizona’s Pinaleno Mountain Range. With more than 800 emergency workers battling it, the fire is at 45 percent containment.

In neighboring Utah, a massive blaze in Brian Head is burning around 60,000 acres, spurring evacuations.

And in California, multiple wildfires have also triggered dozens of evacuations and burned homes and cars.

Disease

The Ministry of Public Health and Population of Yemen has recorded a total of 39,688 suspected cholera cases and 183 associated deaths during the past week 22 to 27 June 2017. According to a World Health Organization Daily Epidemiology update today, 231,364 suspected cholera cases and 1,439 deaths have been recorded since April 27.

Volcanos

Roundup of Global Volcanic Activity – Ongoing Activity for the week of 21 June – 27 June 2017

Bagana | Bougainville (Papua New Guinea) : Based on analyses of satellite imagery and model data, the Darwin VAAC reported that on 22 and 25 June ash plumes from Bagana drifted NW at an altitude of 2.1 km (7,000 ft) a.s.l.

Bezymianny | Central Kamchatka (Russia) : KVERT reported that a powerful explosion at Bezymianny on 16 June generated an ash plume that rose as high as 12 km (39,400 ft) a.s.l. and drifted 700 km E and SE. Nighttime incandescence from the lava dome was observed at night afterwards, and a lava flow emerged from the W flank of the dome. A thermal anomaly was identified daily in satellite images during 16-23 June. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Cleveland | Chuginadak Island (USA) : AVO reported that there have been no detections of anomalous seismicity or infrasound at Cleveland since a brief explosion on 16 May. Satellite-based evidence of continuing lava effusion was observed on 7 June but since then surface temperatures had become weaker. On 26 June AVO lowered the Aviation colour Code to Yellow and the Volcano Alert Level to Advisory.

Dukono | Halmahera (Indonesia) : Based on analyses of satellite imagery, wind model data, and notices from PVMBG, the Darwin VAAC reported that during 21-27 June ash plumes from Dukono rose to altitudes of 1.5-2.1 km (5,000-7,000 ft) a.s.l. and drifted in multiple directions.

Ebeko | Paramushir Island (Russia) : Based on observations by residents of Severo-Kurilsk (Paramushir Island), about 7 km E of Ebeko, KVERT reported that explosions on 17 and 21 June generated ash plumes that rose as high as 2 km (6,600 ft) a.s.l. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Kilauea | Hawaiian Islands (USA) : During 21-27 June HVO reported that the lava lake continued to rise, fall, and spatter in Kilauea’s Overlook crater. Webcams recorded incandescence from long-active sources within Pu’u ‘O’o Crater, from a vent high on the NE flank of the cone, and from a small lava pond (which had many small spattering sites along the margin) in a pit on the W side of the crater. The 61G lava flow, originating from a vent on Pu’u ‘O’o Crater’s E flank, continued to enter the ocean at Kamokuna. Field observations on 31 May revealed that the lava delta had grown to an area of approximately 0.01 square kilometers. A solidified lava ramp extended from the tube exit high on the sea cliff down to the delta, whose leading edge was about 100 m from the tube exit on the sea cliff. Lava flows from the upper portion of the flow field continued to advance downslope, producing surface flows above the pali.

Klyuchevskoy | Central Kamchatka (Russia) : KVERT reported that during 16-17 June a weak thermal anomaly was identified in satellite images at Klyuchevskoy. Explosions generated ash plumes that rose to 6-7 km (19,700-23,000 ft) a.s.l. and drifted about 300 km E and W during 16-17 and 22 June. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Langila | New Britain (Papua New Guinea) : Based on analyses of satellite imagery and wind model data, the Darwin VAAC reported that on 21 June ash plumes from Langila rose 2.1 km (7,000 ft) a.s.l. and drifted NW.

Poas | Costa Rica : OVSICORI-UNA reported low-amplitude tremor with occasional periods of low-amplitude long-period events detected at Poás during 20-25 June. Plumes of reddish-coloured ash, water vapor, and magmatic gases were recorded rising as high as 500 m above two vents during 20-21 June. Magmatic gases and water vapor plumes rose as high as 1 km above the vents the rest of the period.

Sabancaya | Peru : Observatorio Vulcanológico del Sur del IGP (OVS-IGP) and Observatorio Vulcanológico del INGEMMET (OVI) reported that explosive activity at Sabancaya decreased from the previous week; there was an average of 15 explosions recorded per day during 19-25 June. The explosions were also less energetic. Gas-and-ash plumes rose as high as 3.5 km above the crater rim and drifted more than 40 km S. The MIROVA system detected as many as 10 thermal anomalies, spread over the SE, N, and NE flanks. Sulfur dioxide flux was as high as 5,700 tons per day, recorded on 24 June.

Sinabung | Indonesia | 3.17°N, 98.392°E | Elevation 2460 m

Based on PVMBG observations, satellite images, and wind data, the Darwin VAAC reported that during 21-27 June ash plumes from Sinabung rose 3-5.2 km (10,000-17,000 ft) a.s.l. and drifted in multiple directions.

Stromboli | Aeolian Islands (Italy) : INGV reported that during 22-26 June explosions at the N1 vent, one of two vents that comprise Stromboli’s N Area, ejected material as high as 200 m above the vent. Explosive activity at the second vent, N2, ejected tephra 150 m high that fell within the crater terrace as well as beyond the crater rim. Intense spattering at N2 was noted on 26 June. Explosions from the N Area vents occurred at a rate of 10-14 events per hour. Vent C in the CS Area discontinuously puffed, and spattering also occurred on 26 June. Explosions from the S1 vents (also part of the CS Area) ejected tephra 150 m high. Explosions from the CS Area occurred between 5 and 10 events per hour.

Turrialba | Costa Rica : OVSICORI-UNA reported that during 20-25 June seismicity at Turrialba was characterized by low-to-medium amplitude tremor, and a small number of low-amplitude volcano-tectonic and long-period events. Plumes of water vapor and magmatic gases rose as high as 1 km above the crater. The gases were strongly incandescent at night during 22-23 June.
