Italy – Authorities have issued flood warnings across northern Italy as heavy rain has led to widespread flooding. Many rivers have overflowed. The swollen River Po, Italy’s longest, burst its banks in Turin after 171mm of rain fell in just three days. In the 24-hour period up to 06:00GMT on Friday, the city recorded 116mm of rain compared with the November average of only 77mm. Homes were evacuated and schools and public businesses closed in northwestern Italy on Thursday as heavy rain caused the Tanaro River to overflow. Flood warnings have been issued in the regions of Liguria and Piedmont, which have been hardest hit. The bad weather struck the area, sending torrents of waves through the Tanaro and on to river banks and streets.

Brisbane, Australia – Heavy rainfall and widespread flooding has battered south-east Queensland. Stationary storms made their way down the Queensland coastline with bayside suburbs in Brisbane recording almost 100 millimetres of rainfall. Brisbane Airport copped 97 millimetres of rain, mostly between 6am and 7am while Redcliffe received 87 millimetres on Saturday.

Trinidad and Tobago – Citizens throughout Trinidad are today bracing themselves for more flooding with reports of heavy rains. There have been complaints throughout the country and reports of rising flood waters. There are reports that some residents in Mayaro and Rio Claro had to leave their homes while some were marooned due to flood waters yesterday.

Global Warming

Captain Cook’s detailed 1778 records confirm global warming today in the Arctic

in the summer of 1778, when Capt. James Cook tried to find a Western entrance to the route, his men toiled on frost-slicked decks and complained about having to supplement dwindling rations with walrus meat.

The British expedition was halted north of the Bering Strait by “ice which was as compact as a wall and seemed to be 10 or 12 feet high at least,” according to the captain’s journal. Cook’s ships followed the ice edge all the way to Siberia in their futile search for an opening, sometimes guided through fog by the braying of the unpalatable creatures the crew called Sea Horses.

More than two centuries later, scientists are mining meticulous records kept by Cook and his crew for a new perspective on the warming that has opened the Arctic in a way the 18th century explorer could never have imagined. The results, published this month in the journal Polar Geography, confirm the significant shrinkage of the summer ice cap and shed new light on the timing of the transformation.

From the time of Cook until the 1990s, you more or less could count on hitting the ice somewhere around 70 degrees north in August. Now the ice edge is hundreds of miles farther north.

That meshes with modern observations that confirm rapid shrinkage of the Arctic ice pack over the past three decades, Overland said. The total volume of ice in summer is now 60 to 70 percent lower than it was in the 1980s, while Arctic temperatures have increased at twice the rate of the rest of the planet as a result of rising greenhouse-gas levels.

With more melting in the summer and delayed freezing in the fall, the once-elusive Northwest Passage is now navigable for private yachts and commercial vessels.

Disease

Brazil – Chikungunya, Dengue and Zika Virus

The Brazil Ministry of Health reports (computer translated) 855 cities, or approximately 37 percent, are in a situation of alert and risk of outbreak of the mosquito borne viral diseases, dengue, chikungunya and Zika, according to the Fast Index Survey for Aedes aegypti (LIRAa) of 2016 released by the Health Minister, Ricardo Barros yesterday.

Brazil health officials have reported 251,051 suspected cases of chikungunya fever, of which 134,910 were confirmed. In the same period last year, there were 26,763 suspected cases and 8,528 confirmed cases. Chikungunya related deaths stand at 138, according to health officials.

There were 208,867 probable cases of Zika fever nationwide by October 22, representing an incidence rate of 102.2 cases per 100,000 inhabitants. The autochthonous, or local transmission of the virus in the country was confirmed as of April 2015, with laboratory confirmation in Bahia. The Ministry of Health has made notification of Zika cases in February this year compulsory. The Southeast Region had 83,884 probable cases of the disease, followed by the Northeast (75,762); Midwest (30,969); North (12,200) and South (1,052).

Health officials report 1,458,355 dengue cases through Oct. 22. This is a decrease of 5.5% from the 2015 total during the same period in 2015 (1,543,000). Considering the regions of the country, the Southeast and Northeast present the highest number of cases, with 848,587 cases and 322,067 cases, respectively. Next are the Midwest (177,644), South (72,114) and North (37,943).

Volcanos

Roundup of Global Volcanic Activity – Ongoing activity for the week of 16 November-22 November 2016

Sangay | Ecuador : Based on satellite images and wind data, the Washington VAAC reported that during 16-17 November ash plumes from Sangay rose to an altitude of 6.1 km (20,000 ft) a.s.l. and drifted as far as 290 km SE.

Sheveluch | Central Kamchatka (Russia) : KVERT reported that during 11-18 November lava-dome extrusion onto Sheveluch’s N flank was accompanied by strong fumarolic activity, dome incandescence, ash explosions with ash plumes as high as 6 km (19,700 ft) a.s.l., and hot avalanches. Satellite images showed a daily thermal anomaly over the dome, and ash plumes that drifted as far as 170 km E on 12 and 15 November. The Aviation Color Code remained at Orange (the second highest level on a four-color scale).

Sinabung | Indonesia : Based on satellite images, wind data, ground reports from PVMBG, and the Jakarta MWO, the Darwin VAAC reported that on 20 November ash plumes from Sinabung rose to altitudes of 3.3-3.9 km (11,000-13,000 ft) a.s.l. and drifted E.

Suwanosejima | Ryukyu Islands (Japan) : Based on JMA notices and satellite-image analyses, the Tokyo VAAC reported that during 16-17 November explosions at Suwanosejima generated ash plumes that rose to an altitude over 1.2 km (4,000 ft) a.s.l. and drifted S. During 20-21 November ash plumes rose to an altitude of 1.8 km (6,000 ft) a.s.l. and drifted E.

Turrialba | Costa Rica : OVSICORI-UNA reported that tremor and ash emissions at Turrialba ceased on 17 November. Tremor amplitude increased at 0140 on 19 November, though weather clouds prevented visual confirmation of correlating emissions. By 0800 tremor amplitude was low and some long-period events were recorded. Low emissions were mostly white, indicating gas, water vapor, and minor amounts of ash. A small quantity of ash fell in Cartago and Paraíso de Cartago (25 km SW). Tremor amplitude remained low on 20 November. A thin layer of ash deposits were reported in Ipis de Goicoechea, 27 km SW of the crater.

Ulawun | New Britian (Papua New Guinea) : Based on analyses of satellite imagery, the Darwin VAAC reported that during 16-18 November ash plumes from Ulawun rose to altitudes of 2.7-3 km (9,000-10,000 ft) a.s.l. and drifted over 30 km SE, SW, and W.
