Queensland, Australia – Brisbane residents will wake up to a huge clean-up effort this morning after the city was walloped by an extreme hail storm described by Premier Campbell Newman “the worst in a decade”. The army has been called in to help mop up after golf ball-sized hailstones catapulted by destructive winds up to 141km/h slammed into high rise buildings and vehicles in the CBD and surrounding suburbs leaving a trail of destruction yesterday afternoon. At least four light planes were flipped in severe winds at Archerfield Airport causing hundreds of thousands of dollars worth of damage. Queensland Premier Campbell Newman says all available emergency personnel have been mobilised to help with the clean-up.

Canadian Lakes ‘Jellified’ by Acid Rain

Decades of acid rain that have made many Canadian freshwater lakes more acidic have also profoundly altered the ecological balance and turned some lake bottoms to jelly.

Even though pollution controls have long since diminished the amount of acid rain, some affected lakes have not recovered from the pollution and have become home to expanding populations of a tiny, slimy crustacean called the Holopedium.

The invertebrate is surrounded by a bulbous coating of jelly.

Swimmers in affected lakes often emerge from the water with the caviar-like balls clinging to their arms and backs.

Writing in the journal Proceedings of the Royal Society B, researchers document that decades of acid rain have flushed away much of the calcium in the lakes, which Holopedium’s biggest competitor, the Daphnia water flea, needs to create an exoskeleton.

With the formerly dominant Daphnia now deprived of enough calcium to bulk up, and gradually disappearing, Holopedium has been able to reproduce unchecked since it needs far less calcium to make its gooey shell.

This competitive edge is creating a jellied mess that threatens to clog water intake systems in the lakes for residential and commercial use.

Ebola Outbreak, West Africa – Update

Sierra Leone has appealed to the United States on Wednesday to send military aid to help it battle Ebola as it falls behind its West African neighbours Guinea and Liberia in the fight against the virus.

The worst recorded Ebola outbreak has killed at least 5,689 people, the World Health Organization said on Wednesday, as the virus has overwhelmed African countries with weak infrastructure and healthcare systems.

While the outbreak appears to be coming under control in Liberia, thanks partly to a health operation run by U.S. troops, infection rates have accelerated in Sierra Leone.

The rate of transmission is also beginning to slow in neighbouring Guinea, the first country to report an Ebola case, although case numbers are rising in Mali.

Jaundice Outbreak in India

An outbreak of jaundice in Saraspur has left 199 people affected in the last three weeks. There were nine new cases on Thursday across 24 chawl clusters in the area. Ahmedabad Municipal Corporation (AMC) health officials were yet to confirm four additional jaundice cases.

“The jaundice strain is hepatitis E, which is not lethal among all those who are affected,” says a senior AMC health official.


Global Temperature Extremes

The week’s hottest temperature was 113.9 degrees Fahrenheit (45.5 degrees Celsius) at Oodnadatta, South Australia.

The week’s coldest temperature was minus 56.7 degrees Fahrenheit (minus 49.3 degrees Celsius) at Russia’s Siberian weather station in Agata.

Temperatures were tabulated from the more than 10,000 worldwide synoptic weather stations. The United Nations World Meteorological Organization sets the standards for weather observations, and provides a global telecommunications circuit for data distribution.
