Storms and Floods

Tropical Storms – Roundup of Tropical Storms:

No current tropical storms.


Spain – Southeast Spain saw a record amount of rain on Monday, causing riverbeds to overflow and roads to flood as the region faced its worst floods in 20 years. Half of the average annual rainfall fell in Alicante in just one day as more than 150litres of water per square metre hit the area. At least one man had to be rescued from his vehicle after it became submerged in floodwaters when it was swept away into the Serpis River. Schools across the province shut down for the day as Spain’s weather agency said the stormy weather was expected to continue through Tuesday.


New CO2 record

The atmosphere’s carbon concentration now exceeds 1960 levels by about a third, and rises faster each decade.

The concentration of carbon dioxide rose by 3 parts per million (ppm) for the second year in a row in 2016, bringing the average concentration to a record-setting 405 ppm, according to the National Oceanic and Atmospheric Administration (NOAA).

Pre-industrial concentrations rarely exceeded 280 ppm, and some estimates suggest we would need to keep the carbon concentration between 405 and 450 ppm to limit warming to the internationally set target of 2 degrees Celsius (3.6 degrees Fahrenheit). But while that concentration rose by less than one part per million annually in the 1960s, the current annual increase of 3 ppm would put Earth in the danger zone by the early 2030s.

Massive Thirsty Mangroves Dieback Due To Extreme Weather Condition

A James Cook University researcher has found why there was an uncommon dieback of mangroves in the Gulf of Carpentaria in mid-2016 – the plants died of thirst.

The researchers used aeronautical observations and satellite mapping information of the area going back to 1972, joined with climate and weather records. Dr. Duke said they discovered three factors met up to create the extraordinary dieback of 7400 hectares of mangroves, which extended for 1000 kilometres along the Gulf coast.

“From 2011 the coastline had experienced beyond normal rainfalls, and the 2015/16 dry season was especially serious. Secondly, the temperatures in the zone were at record levels and thirdly a few mangroves were left high and dry as the ocean or sea level dropped around 20cm during a particularly extreme El Nino.”

Human infection with avian influenza A(H7N9) virus – China

Between 24 February and 7 March 2017, a total of 58 additional laboratory-confirmed cases of human infection have been reported to WHO from mainland China and China, Hong Kong Special Administrative Region (SAR).

Another outbreak of White Spot disease in Queensland, Australia

Queensland’s $360 million prawn industry has been dealt another blow with news the troublesome white spot virus has spread into Moreton Bay.

Agriculture and Fisheries Minister Bill Byrne says the virus that causes the disease has been detected near the Redcliffe Peninsula and Deception Bay.

Mr Byrne says the state government’s established a movement control order to prevent its spread, which will be in place for three months to allow further testing before determining future action.


Roundup of Global Volcanic Activity – New Activity for the week of 8 March-14 March 2017

Chirinkotan | Kuril Islands (Russia) : SVERT noted that no further activity at Chirinkotan was visible after the ash emission on 1 March. The Aviation Colour Code was lowered to Green (on a four-colour scale) on 5 March.

Ebulobo | Flores Island (Indonesia) : Based on PVMBG observations, the Darwin VAAC reported that on 12 March an ash plume from Ebulobo rose to an altitude of 3 km (10,000 ft) a.s.l. (800 m above the summit) and drifted W.

Klyuchevskoy | Central Kamchatka (Russia) : KVERT reported that a thermal anomaly over Klyuchevskoy was identified in satellite data during 2-3, 5, and 8-9 March. Explosions on 8 March produced ash plumes that rose to an altitude of 5.5 km (18,000 ft) a.s.l. and drifted about 20 km NW. The Aviation Colour Code remained at Orange (the second highest level on a four-colour scale).
