Spain – Spain’s forecaster has issued a red weather alert for the Costa Blanca around Benidorm and Alicante after Majorca was hit by severe rain, hail and a tornado. The adverse weather conditions that affected the north-east of Spain earlier this week moved on to the eastern region of the Balearic Islands, causing power problems and flash floods. The holiday hotspots of southern Spain are facing a washout as the severe weather which lashed the Balearic islands hits the mainland.

Niger – Deadly floods across Niger have left 57 people dead and affected more than 130,000 since they began in June, according to the latest government toll. Niger’s government said in a statement late Tuesday the floods had resulted in 57 deaths and that 132,528 people had been affected. The rains had destroyed over 12,000 houses, killed more than 850 cattle and engulfed more than 2,000 hectares (nearly 5,000 acres) of crops.

Climate Change and the Looming Omega-3 Crisis

Algae are the small but mighty, responsible for synthesizing most of the world’s docosahexaenoic acid (DHA). The plants provide DHA to fish and sea creatures, many of which end up on the plates of seafood lovers everywhere. But algae are particularly sensitive to changes in ambient temperature — and warmer waters have already started disrupting algae’s DHA synthesis.

A new study, published Wednesday in the journal Ambio, predicts that by 2100, 96 percent of the global population may not have sufficient access to a DHA, the naturally occurring essential brain-building omega-3 fatty acid.

DHA is a key component of cell membranes and is critical for brain function. It helps regulate cell survival, inflammation, and neuroprotection, and makes up 10 percent of the mammalian brain’s fatty acids. DHA is also thought to help develop the central nervous system and retina.

But humans can’t produce enough DHA on their own. To reach the recommended dose — 1.1 g for adult women and 1.6 g for adult males daily — they either have to eat DHA-rich foods like fish and seafood once or twice a week, or take dietary supplements.

As DHA production declines and human population explodes, humans all over the world will likely become DHA deficient. Basically, too many people and not enough seafood will lead to health complications.

Wildfires

Wildfires Fully Extinguished in Siberia’s Irkutsk Region

Wildfires that burned across swathes of Siberia this summer have been fully extinguished in the Irkutsk region, Interfax cited regional authorities as saying Wednesday.

Irkutsk is one of several regions that have been affected by the “unprecedented” wildfires throughout Siberia since June. The wildfires exceeded 3 million hectares, an area the size of Belgium, at their peak in July.

Disease

Gastroenteritis – Australia

Officials with New South Wales Health (NSW Health) urging parents and carers to keep young children at home if they are sick amid a rise in viral gastro cases. NSW Health’s Acting Manager of Enteric and Zoonotic Diseases said the warning has been prompted by an increase in gastroenteritis outbreaks at childcare centres across the state and a high number of children aged under 5 seeking treatment at emergency departments. “Nearly 100 childcare centres reported outbreaks of gastro in August and at least 820 children and 165 staff have fallen ill.”

Global Volcanic Activity – New Activity for the week of 4 September – 10 September 2019

Villarrica | Chile : ONEMI and SERNAGEOMIN reported that the seismic network at Villarrica recorded significant variations in seismicity beginning at 0030 on 8 September, characterized by an increase in the number of long-period (LP) events from 20 to 50 per hour. LP events ceased to be detected around 1030 and short periods of high-energy tremor began. Weather clouds prevented views of the summit crater, though the characteristics of the seismicity indicated fluctuating lava-lake activity. The increased seismicity persisted on 9 September, prompting SERNAGEOMIN to raise the Alert Level to Orange, the second highest level on a four-color scale. ONEMI has maintained an Alert Level Yellow (the middle level on a three-color scale) since 6 August for the municipalities of Villarrica, Pucón (16 km N), and Curarrehue, along with the commune of Panguipulli and stated that the public should stay at least 2 km away from the crater. On 10 September seismicity remained high; infrasound signals were recorded at a rate of 50 events per hour.
