Floods in South Sudan affecting nearly a million people - year's worth of rain falls in weeks

Women carry belongings on their heads as they wade through water, after heavy rains and floods forced hundreds of thousands of people to leave their homes, in the town of Pibor, Boma state, South Sudan, Nov. 6, 2019.
Women carry belongings on their heads as they wade through water, after heavy rains and floods forced hundreds of thousands of people to leave their homes, in the town of Pibor, Boma state, South Sudan, Nov. 6, 2019.
The World Food Program says nearly a million of South Sudan's 11 million people have been affected by devastating floods and are in urgent need of life-saving assistance.

The government has declared a state of emergency in Bahr el Ghazal, Greater Upper Nile and Greater Equatoria states. It is appealing for increased international support to help it deal with this natural disaster, the worst in many years.

The United Nations reports a year's worth of rain has fallen in a matter of weeks in some areas, washing away homes and livestock. Airstrips and roads are unusable, making many remote areas inaccessible.

The World Food Program reports tens of thousands of people are homeless and living in temporary shelters. Even before the rains fell, the agency notes 4.5 million people in the country did not know where their next meal was coming from.

Weather likely to cause drop in US potato yields

harvest
Weather issues in both the upper Midwest and Idaho mean potatoes could be in short supply this year.

In the Midwest, Minnesota has experienced a number of issues that could cause its volume of potatoes to be lower this season. "We got a late planting—so Wisconsin, Minnesota and North Dakota—and that knocked some yield off of the crop," says Rett Landers of Northern Star Co. in Minneapolis, Minn. He says that while the growing season went well, harvest was wet which also caused issues. "So I'd say in the upper Midwest, the yield will be off probably five per cent," he adds.

North Dakota saw cold temperatures that affected harvest as well. "There were a number of acres that didn't get harvested before the cold weather hit. I think the red volume will be affected there," Landers says, adding that Minnesota's yields will likely be off between three to five percent.

Floods and landslides caused by Tropical Storm Nakri kill at least 7, affect thousands in the Philippines

Rescuers help residents displaced
Rescuers help residents displaced by a massive flood in Cagayan province.
The number of people affected by floods and landslides that struck Cagayan this week has ballooned to 63,287 people, or 10,887 families, as of Saturday, Nov. 9, according to the Provincial Disaster Risk-Reduction Management Office.

They were displaced by high waters that inundated 155 barangays in 14 towns, said Rogelio Sending Jr., Cagayan information officer.

Strong rainfall brought by Severe Tropical Storm Quiel (internationally known as Nakri) triggered flooding and landslides that killed five people.

Four of the dead were residents of Barangay Imurung in Baggao town — Bagga Eljhay Dallego, 10; Augusto Jamon, 36; Jeremiah Saring, 14, and Ariel Agustin Versola, 32.

'Biblical': Hundreds of flood warnings across England as a month's worth of rain falls in ONE DAY

houses flooded uk
Homes are submerged by rising flood water on Yarborough Terrace in Doncaster today as people had to be evacuated
Hundreds of flood warnings remain in place across England today as rain continues to pummel the country, with some posing a "danger to life".

A total of 125 red flood warnings and a further 118 amber flood alerts stretch from Sunderland in the north to the Isle of Wight in the south.

The flash flooding caused by torrential downpours is expected to spark more misery for commuters and residents.

Five 'severe' warnings are active and relate to towns and villages surrounding the River Don which are in immediate risk.

The river in Doncaster burst its banks yesterday and will reach its highest recorded level today, forecasters predict.


Comment: The Daily Mail reports further on the chaos the flooding is causing:
Prime Minister Boris Johnson has arrived in flood-hit Derbyshire after parts of Britain suffered chaos today as a woman's body was recovered from floodwater, drivers were stranded in their cars and people were forced to sleep in a shopping centre overnight.
Doncaster

A woman was swept away by floodwater in Rowsley, Derbyshire, in the early hours before her body was found in Darley Dale at 10.40am following what residents of South Yorkshire described as 'biblical' amounts of rain.

Aerial photographs showed devastating scenes in Doncaster, where residents were rescued from their homes as waist-high water filled the street. One local said water trickled along 'like a shadow' before covering the road.

Yorkshire and the Midlands were the worst affected areas, with six severe 'danger to life' warnings in place as fire crews were called in to help guide people to safety, while many rail and road users were warned against travelling.

Customers slept on benches while restaurant workers used their aprons as pillows at Meadowhall shopping centre in Sheffield, while firefighters used boats to rescue others stranded at the Parkgate mall in nearby Rotherham.
Sandbags

A major incident was declared in Sheffield as the Environment Agency issued 121 flood alerts and 117 more serious flood warnings for England today, with the risk not expected to pass for many areas for several days to come.

Some 35 homes were evacuated in Mansfield after a mudslide at a quarry, while other areas were hit by traffic chaos amid road closures - with more of the same in this morning's rush hour after a further deluge overnight.

Rail operator Northern has issued 'do not travel' advice for passengers using five lines - Sheffield to Gainsborough, Sheffield to Lincoln, Sheffield to Goole, Hebden Bridge to Rochdale, and Sheffield to Leeds via Moorthorpe.

Residents of Toll Bar, near Doncaster, which was hit by flooding in 2007, have told how 'almost biblical' rain came pouring down. Parts of the village were still submerged this morning, with locals on 'red alert' for further flooding.

Doncaster Council warned some people to leave their homes because the River Don is breaching its banks near St Oswald Church at Kirk Sandall, tweeting: 'Residents in these areas are advised to evacuate immediately.'

Changes in high-altitude winds over the South Pacific produce long-term effects

Changes in Ocean-Atmosphere System
© Graphic: Helge Arz, IOWSchematic depiction of changes in the ocean-atmosphere system in the South Pacific in comparison, throughout the precession cycles (21,000 years).
In the past million years, the high-altitude winds of the southern westerly wind belt, which spans nearly half the globe, didn't behave as uniformly over the Southern Pacific as previously assumed. Instead, they varied cyclically over periods of ca. 21,000 years. A new study has now confirmed close ties between the climate of the mid and high latitudes and that of the tropics in the South Pacific, which has consequences for the carbon budget of the Pacific Southern Ocean and the stability of the West Antarctic Ice Sheet. The study was prepared by Dr Frank Lamy, a geoscientist at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, together with researchers from Chile, the Netherlands, the USA and Germany, and has just been released in the Proceedings of the National Academy of Sciences of the United States of America (PNAS).

Changes in the southern westerly wind belt produce fundamental effects on the intensity and position of the Antarctic Circumpolar Current, which is the world's largest ocean current and shapes ocean circulation worldwide. In this regard, one key factor is the wind-driven upwelling of CO2-rich deep-water masses, which, due to their comparative warmth, influences both the stability of the West Antarctic Ice Sheet and the carbon budget of the Southern Ocean.

On the basis of sediment cores, the team of researchers investigated precipitation-driven changes in sediment input in the Pacific off the coast of Chile. Assessing the past 1 million years, they identified what are known as precession cycles: changes caused by natural variations in the Earth's orbital parameters; in this case, cyclical changes in the rotation of its axis that occurred roughly every 21,000 years. Changes in these and other orbital cycles are generally considered to be a major driver for the alternation between extended glacials and interglacials over the past million years.
