Iceland – The powerful storm that lashed over Reykjavík and wider Iceland last night and this morning has caused all kinds of damage. In the harbour fences and metal containers were flying around in the winds, which reportedly got up to 50mps.

Ohio, USA – The Ohio River remains in flood, measured at 57.7 feet at 5 a.m. Sunday – 5 feet above flood stage. The National Weather Service predicted the river would crest at 57.8 feet Sunday morning and then begin to fall in the afternoon. The river will likely remain at a moderate flood state until Monday evening and a minor flood state until Thursday evening.

Dire Warning For Food Production As Climate Becomes Warmer

A report which examines the effect of climate change on some of Australia’s most common agricultural products – including fruits, vegetables, grains, dairy, seafood and meat – paints a dire prediction of future production in a warming world.

The Appetite for Change study suggests farming will need to relocate to new regions and find new drought-tolerant varieties or face much reduced, or poorer quality yields for many of the country’s key agricultural products.

Wine grapes

– Up to 70 per cent of Australia’s winegrowing regions with a Mediterranean climate will be less suitable for grape growing by 2050.

– Iconic grape-growing regions, such as Margaret River in WA, the Barossa and Riverland in SA, Sunraysia in Victoria, and the Riverina in NSW, will be the most affected by higher temperatures and lower rainfall, especially for red varieties such as shiraz, cabernet sauvignon and merlot.

– Conditions for wine growing will improve in places like Tasmania.

Scallops

– Southern scallops are fished in Victoria and Tasmania, seas off southeast Australia are warming faster than anywhere else in the southern hemisphere.

– Warmer water, together with changes in oxygen and food, may mean southern scallops effectively disappear from our plates.

– Both northern (Saucer scallops) and southern scallops will have to cope with more acidic seawater, which is likely to thin their shells, reduce their growth, survival and reproductive success and make them less able to elude predators.

Dairy

– Milk volume and quality for cheese production is likely to be affected by warmer temperatures and increased frequency of heatwaves.

– Heat stress on dairy cows typically reduces milk yield by 10 to 25 per cent, and as much as 40 per cent in extreme heatwaves.

– Heatwaves also reduce pasture quality, leading to a decline in the quality of milk for cheese production

Peaches

– Without enough winter chill, flowering is disrupted, leading to lower yields of fruit.

– Climate change effects on peach growing will differ greatly among regions.

– Minimal impacts anticipated for Tasmania.

– South-west of Western Australia expected to experience notable declines in cold weather.

Wildfires

Wildfires – USA

Mandatory evacuation orders are in place for part of St. Joseph because of a 5-mile long wildfire that broke out Sunday afternoon. People in the area said the fire started in Elwood, Kansas, and jumped the Missouri River into St. Joseph, Missouri,

People have been ordered out of homes along Elwood Street in St. Joseph, and firefighters want people to stay away from an area between Wyeth Hill south to River Front Park downtown.

Volcanos

Roundup of Global Volcanic Activity

Dukono (Halmahera): A relatively large ash plume reaching 13,000 ft (4.2) km altitude was observed yesterday extending 50 km ENE (Tokyo VAAC).

Turrialba (Costa Rica): The volcano has remained calm for the past 36 hours, but OVSICORI-UNA warns that new explosions are likely in the near future. The volcano continues to show elevated seismic activity. Only weak degassing has been occurring today from the western crater (which produced incandescent ejections and ash emissions on 13-14 Mar), but this could be likely due to a blocking of the conduit to be released by the next explosion.
