Heatwave in Australia continues, tennis tournament hit | Australia News

Marble Bar, a small town in western Australia, set a new record in December as it touched a gruelling temperature of 49.4C.

On Sunday, it was 49.2C, equalling January’s record of maximum temperature. It was also the 27th day in a row when the mercury remained above 40C in the city.

Marble Bar is one of the hottest towns in Australia. Its average maximum temperature in January is 42C, which is also combined with low humidity.

The new record was set with a relative humidity of 8 percent. It is this factor that allows humans to survive such heat since the sweat from our bodies cools us down. (That and air conditioning.)

Unsurprisingly, there is a limit to human endurance. When extreme daytime heat is combined with hot nights, the risk of heat stress or heatstroke greatly increases.

The equalling of record on Sunday followed a night where temperatures remained above 30C with a relative humidity of 40 percent.

That may be hard to imagine, but saunas attempt to reproduce this for short periods. Such heat produces a lot of perspiration, but little evaporation. 

This heat has spread across Australia’s vast interior, through its southern parts to the state of Victoria.

Australian Open feels the heat

In Melbourne, the Australian Open tennis tournament started with a heatwave forecast.

The conditions on Monday were normal: 31C in the shade and about 45 percent relative humidity. This may reasonably be described as “warm and sticky”.

Last year, the temperature in the shade hit 40C halfway through the tournament.

This year, the forecast highs are around 33C for the first week, but the start of the second week might again bring temperatures near 40C.

The organisers are ready. There is a new Australian Open heat policy, whose five-step scale allows a differing response to rising heat on the tennis court.

Under the new system, 10-minute breaks will be allowed in men’s singles matches for the first time in a grand slam tennis tournament.

The scale is based on the maximum heat stress an athlete can safely withstand, the sweat rate of players and their core temperatures.

Though the risk looks lower this year than the last, Monday, Tuesday and Wednesday remain the biggest heat threats.

Ottawa transit commission hopes to prioritize COVID-19 vaccines for OC Transpo workers

Ottawa’s transit commission is pushing local and provincial health officials to recognize the role OC Transpo operators have played in keeping the city running during the COVID-19 pandemic, hoping to bump train and bus drivers in the vaccination queue amid a recent surge in coronavirus infections affecting transit workers.

More than 100 OC Transpo staff across the entire organization have tested positive for the coronavirus since the start of the pandemic, according to an update at Wednesday morning’s transit commission meeting.

Of those cases, 26 employees are currently recovering from the disease in self-isolation.

OC Transpo has seen a recent jump in COVID-19 cases, with Ottawa city council receiving reports of eight operators testing positive for the virus over a recent eight-day period.

Transit commissioner Sarah Wright-Gilbert attempted to find out how many of the total cases are traced to workplace transmission, but OC Transpo boss John Manconi said he’s been advised by medical officer of health Dr. Vera Etches that he can’t share that information for privacy reasons.

Transit operators are listed in the second priority group of essential workers as part of Ontario’s COVID-19 vaccine sequencing plans, but several commissioners speaking Wednesday wanted to get the city’s bus and train drivers bumped higher in the order.

Councillors Riley Brockington and Glen Gower both put forward motions looking to get front-line OC Transpo employees prioritization in vaccine sequencing, but others pointed out that the much-debated public health topic of who gets the vaccine and when is well beyond the scope of the transit commission.

“We are not in a position in transit commission to be decreeing, or making an edict, about what group of essential workers is more at risk than others and should be prioritized. That should be left up to public health experts,” Wright-Gilbert said.

Knoxdale-Merivale Coun. Keith Egli, who also chairs the Ottawa Board of Health, reflected on the board’s four-plus-hour meeting on Monday evening, during which vaccine sequencing and prioritizing essential workers dominated the conversation.

“Vaccine sequencing is obviously a very difficult maze to get through,” he said.

COVID-19: Ottawa police announce end of 24-7 presence at Ontario-Quebec border

Less than two days after the Ontario government’s latest COVID-19 restrictions came into effect, calling for non-essential traffic to be stopped at the province’s borders with Quebec and Manitoba, the Ottawa Police Service has announced it is stopping its 24-hour checkpoints.

According to a statement issued by the service Tuesday evening, the around-the-clock border checkpoints were set to end as of 8 p.m. on Tuesday in favour of rotating checkpoints across the city throughout the day until Ontario’s temporary regulations end.

“Since the onset of the border operations, the OPS has been working closely with Ottawa Public Health (OPH) along with local stakeholders and interprovincial stakeholders (the City of Ottawa, the City of Gatineau, the Ontario Provincial Police etc.) to assess any local public health, traffic and safety impacts. The assessment resulted in today’s operational changes,” the statement said.

“The operational changes announced today are designed to better ensure the health and safety of all, to minimize delays and/or hazards for travellers and to ensure essential workers can get to their places of employment on time.”

The statement also said the police service, while working to comply with the provincial order, was focused on education and enforcement actions that “support improved public health outcomes and respect the concerns of our most marginalized and racialized communities”

Officers said they will be conducting daily assessments on border crossings and that there could be further changes.

In a statement to Global News, a spokesperson for Solicitor General Sylvia Jones said that the border closures are ultimately subject to the discretion of local police enforcing the regulations.

“Local police services are best positioned to determine the operational deployments necessary to ensure the continued safety of their communities,” the spokesperson said, noting that the order’s regulations still apply to individuals entering the province.

The temporary order restricts Quebec residents from entering Ontario. If prompted, individuals must stop when directed by an enforcement officials and provide their reason for entering the province.

The main exemptions to the restrictions include if the person’s main home is in the province, if they work in Ontario, if they’re transporting goods, if they’re exercising Indigenous or treaty rights, if they need health care or if there’s a basis on compassionate grounds.

COVID-19 vaccines in Ottawa: Nearly half of all residents in their 60s have at least one dose

OTTAWA — Ottawa Public Health’s latest COVID-19 vaccination update shows that nearly half of all residents 60 to 69 years old have had at least one dose of a COVID-19 vaccine, a figure that has all but doubled in the past week.

OPH’s COVID-19 vaccination dashboard shows 58,000 residents 60 to 69 have had at least one dose of a COVID-19 vaccine, accounting for 49.3 per cent of that age group’s population in Ottawa. Last Wednesday, OPH reported 30,000 residents 60 to 69 had had at least one dose, which was 25.4 per cent.

As age demographics get younger, the population grows larger and the coverage by percentage may appear to grow more slowly, even if clinics are vaccinating greater numbers of people. For example, the latest figures show that 83 per cent of people aged 70 to 79 have had at least one dose. By raw population that’s 60,000 people, only slightly higher than half of all people in their 60s.

Vaccinations are open through the Ontario portal to anyone 60 and older and, this week, the AstraZeneca vaccine was approved for administration at pharmacies and primary care clinics to anyone in Ontario 40 and older.

OPH reported a new shipment this week of 25,740 doses of the Pfizer-BioNTech vaccine. To date, Ottawa has received 305,130 doses of COVID-19 vaccines from the provincial government.

The number of eligible residents (i.e. 16 and older) with at least one dose of a vaccine is now up to 28 per cent.

Tuesday was Ottawa’s second-busiest day for vaccinations overall, with the OPH reporting 9,729 shots administered. Last Friday saw 9,887 shots administered in a single day.
