Australian cities could soon be uninhabitable because of extreme heat with 'brutal' global warming already making temperatures soar to SEVENTY degrees (?)
What a lot of slime! The alleged 70 degrees reported was the temperature reached by bitumen roads at midday on a dry sunny day in the tropics. No air temperature ever gets near that. And bitumen roads in the tropics have always got very hot -- so hot that the bitumen sometimes melts. It is neither unusual nor diagnostic of anything. I well remember sitting on my verandah in the tropics one Christmas day long ago and watching the heat waves rise like worms from the bitumen road outside
And you can't draw global conclusions from what happens in one country. Australia is at the moment having a hot spell but at the same time Britain is having an unusually cold spell. The two average out to say nothing global is happening. I reproduce both the Australian and British reports below
Climate scientists have warned that some Australian cities could become 'virtually uninhabitable' due to a combination of blistering heat and smothering humidity.
In the past week alone, surface temperatures in parts of Darwin's inner city have been nudging 70C - and experts have told news.com.au that some regional cities in Queensland 'may not be far behind'.
This year, Bureau of Meteorology senior climate liaison officer Greg Browning warned Darwin residents that 'everything would be hotter than normal' in the lead-up to the wet season.
Average temperatures all over the country have been shattering records all year, with Hobart's recent run of six consecutive November days unparalleled in 130 years.

Sydneysiders are also in the midst of the warmest November week in nearly 50 years, ending a dismal run of rain and cooler temperatures.
A prolonged run of uninterrupted warm weather is due to hit the city with temperatures set to reach or exceed 25 degrees every day until the end of November.
'The last time this happened in November was in 1968, and it's only happened four times in the last 160 years,' Weatherzone meteorologist Brett Dutschke told Daily Mail Australia.
The last times Sydney basked in seven consecutive days of temperatures at or above 25 degrees were in 1968 and 1897.
The consistently warm weather is the result of a high pressure system - known as a 'blocking high' - that is centred over the Tasman Sea and is stopping any strong cold fronts from moving up Australia's east coast.
And it's not just Sydney that's rolling into summer - Melbourne residents have had sweltering spring temperatures for the past week, enduring the longest stretch of November days exceeding 28 degrees on record.
Australian National University's Dr Elizabeth Hanna warned that the issue would mostly affect the Top End due to the tropical humidity.
'We can cope with much higher temperatures in Melbourne because the air is drier, but in Darwin the high temperatures and humidity are oppressive.
'If it gets worse, those unpleasant times of the year (like the build-up) will extend longer and longer making it not a viable place to live,' she told the news site.
Professor Mattheos Santamouris explained that the way to combat climate change and battle rising temperatures is to 'understand what is happening at a local level'.
He warns that if Australia can't find a solution, the cities will eventually become 'uninhabitable'.
But it's not just the environment that will suffer - when it's oppressively hot, people feel 'crappy and grumpy' which impacts on people's social behaviour.
Professor Samtamouris recommends planting more greenery - the surface temperature of grass in the city of Darwin is only 27.4øC, while bitumen can have a surface temp of nearly 70øC
Three months ago, the Territory Government kicked off a project to see where Darwin's hot spots were - and what was causing them - so they could cool down the CBD.
'The study found our streets, parking lots, roofs and pavements have very high surface temperatures, ranging from 45-67C,' said Chief Minister Michael Gunner at the time.
'Areas such as the Post Office carpark, the Supreme Court car park, and the Bus Terminal are incredibly hot - Cavanagh Street (the CBD's main thoroughfare) is a river of fire.'
Professor Samtamouris told news.com.au Darwin was a 'classic case of an urban heat island' where materials used in roads and buildings 'turbocharged' temperatures.
Excessively hot surface temperatures can raise the temperature around them - for instance, black bitumen can heat the air by around 3ø - which is why Professor Samtamouris recommends more greenery in the city.
He also suggests building with alternative materials, like 'cooling' asphalt which works to bring own the surrounding air temperature.
The urban heat island effect is being felt most strongly in Darwin, but the rest of Australia may not be too far behind.
'Townsville and Cairns are not as bad but they will start to become like Darwin. Everything is just moving to the extreme but we just don't know exactly when or how fast it will happen,'' warned Professor Hanna.
'Global temperatures are going so badly and emissions are increasing so much that it's not looking good.'
Planting more trees and creating shady streets was a good strategy to make cities more liveable, she said, but as temperatures continue to rise, there's only so much that plants can do.
Britain is gripped by a deep FREEZE: Health chiefs warn of 'very real risk' of deaths as temperatures plummet to -4C and November looks set to be coldest on record
Just as quickly as the temperatures across Britain dropped this weekend, bookmakers have slashed the odds on November to be the coldest on record.
Britain is facing more sub-zero temperatures tonight as the cold snap which has braced the nation is expected to bite again.
The mercury dipped to -3.5C (25.7F) in Hurn, Bournemouth, while South Newington reached -2C (28.4F) and Drumnadrochit, near the Loch Ness dipped to -1.7C (28.94F), while health watchdogs have urged people to prepare for a prolonged cold snap.
Ladbrokes slashed their odds to just 5/2 that November will be the coldest on record. The betting firm has also slashed the odds of the UK seeing a White Christmas to just 8/15, while Coral is offering 4/6 on the same bet.
Jessica Bridge of Ladbrokes said: 'The sun might be shining but the odds are shivering south as much as the mercury is. It looks like the UK could finally see a proper White Christmas this year.'
Weathermen believe records may have been broken as this weekend was the fifth autumn weekend which saw temperatures fall below at least -4C.
The Weather Outlook forecaster Brian Gaze said: 'All regions are at risk of rain, sleet and snow later in the week.
'Five autumn weekends in a row each having sub-zero cold snaps must be a record.'
And the low temperatures are likely to see a new level 2 Government health warning as hospitals prepare be to busier than usual., while staff prepare to make daily visits or phone calls to the vulnerable. Figures earlier this week showed there were more than 34,000 'excess deaths' across England and Wales over the last winter period, the second highest level in eight years.
But despite the chilly temperatures last night, the mercury did not drop near to this Autumn's lowest temperature of -6.3C which was recorded this Friday in Topcliffe, North Yorkshire.
On Saturday there were smatterings of snow in parts of Scotland and the West Midlands, with more forecast for higher parts of Wales, the Pennines and parts of Northern Ireland overnight.

A yellow weather warning was issued for the length of the western side of Britain and Northern Ireland from 10pm on Saturday until 10am on Sunday, alerting people to the risk of ice.
Yet the weather warnings have now been lifted, although a Met Office spokesman warned people living in coastal areas to remain vigilant as there is the possibility that showers which happen into this evening and overnight could pose a risk of icing over.
Heading into next week, the Met Office warned of snow as far south as Essex by Wednesday, with the East, Northern Britain and Wales all due low-level snow near coasts.
While temperatures will remain similar to the 3-6C that most of Britain felt during the day this weekend, the bitter polar winds next week could make it feel a bitter -1 to -2C.
Temperatures in some parts of Britain could plummet to a brisk -7C on either Wednesday or Thursday in both Scotland or England, which would beat Saturday morning's low of -6.3C in Topcliffe, North Yorkshire.
Met Office forecaster Luke Miall said: 'It turns cold again from Monday afternoon and stays colder-than-average through the week and for up to 10 days, with winds from the Arctic.
