Koala takes a dip during 40C heatwave

  Koala takes a dip during 40C heatwave It was not just the people of Adelaide trying to beat the heat yesterday, with a koala filmed taking a dip in the city’s east. The woman who filmed the marsupial told Adelaide Now the koala tumbled down the bushes and into a pond at the Morialta Conversation Park about 11am.It then spent about 10 minutes splashing around.“We had seen other koalas up in the trees but nothing like this; it was just lovely,” she told the newspaper.“He seemed to be enjoying himself.”A swim was in order after some parts of Adelaide reached 40C yesterday.Adelaide is expecting another scorcher today with the mercury forecast to hit 35C.

"It's never been that hot before," climate scientist Jim Salinger said.

"We looked at records back to 1900 and there's nothing anywhere near this."

Fishers in Doubtful Sound and Fiordland had reported catching snapper for the first time, while there are also anecdotes from surf life savers of bluebottle jellyfish appearing much earlier than normal, Dr Salinger said.

Starfish eating Australia's Great Barrier Reef alarm scientists

  Starfish eating Australia's Great Barrier Reef alarm scientists A major outbreak of coral-eating crown of thorns starfish has been found munching Australia's world heritage-listed Great Barrier Reef, scientists said on Friday, prompting the government to begin culling the spiky marine animals. The predator starfish feeds on corals by spreading its stomach over them and using digestive enzymes to liquefy tissue, and the outbreak hits as the reef is still reeling from two consecutive years of major coral bleaching.

The balmy ocean tenperatures were being driven by a combination of two different climate patterns: the southern annular mode, and a La Nina weather system, he said.

The southern annular mode was in its positive phase, meaning westerly winds that swirled around the Southern Ocean had contracted towards Antarctica.

Dead shark prompts calls to remove nets

"We've not had the usual incursions ... of strong westerly winds, so that's really shut the door from the Southern Ocean for outbursts of cold air and rough weather to stir up the Tasman Sea."

The La Nina pattern meant more north-easterly winds, which encouraged the warm east Australian current to come further south towards New Zealand, Dr Salinger said.

Readings from floating gauges monitored by NIWA showed the warmer water was up to 50m deep, he said.

Our Changing World host Alison Ballance said extreme systems like the heatwave could have a profound affect on marine ecosystems.

Kaikōura biologist Jim Mills, who studied red-billed seagulls, had told her the warm water meant krill in the ocean was pushed much further down, beyond the reach of gulls who normally fed it to their young.

Instead, the gulls were feeding their chicks fish larvae and jellyfish - "anything they can find", Ms Ballance said.

Bill Gates promised to pay off this country's $76 million debt — now he's doing it .
The repayments, which will be made over the course of 20 years, are due to begin this year. Nigeria had no new cases of polio last yearIn 2014, Nigeria borrowed the money from Japan to fund its fight against the preventable disease, Quartz reports. The Gates Foundation had agreed to repay the loan if Nigeria met certain conditions, namely "achieving more than 80% vaccination coverage in at least one round each year in very high risk areas across 80% of the country's local government areas," according to an email from the foundation to Quartz.
