The smoke from the Australian fires reached Auckland, New Zealand today. My daughter sent these pics today.

Australia wildfires developing their own 'dangerous' weather systems, New Zealand skies turn orange
The wildfires that are ravaging parts of Australia are burning through vegetation under such extreme conditions the blazes are generating enough heat to create their own weather systems, including fire-generated thunderstorms and fire tornadoes.​
..."It's not something we have experienced before," New South Wales Premier Gladys Berejiklian said.​
The explosive storms can form during a fire when heat and moisture from the plants are released, even when the fuel is relatively dry. Mike Flannigan, a fire scientist at the University of Alberta in Canada, told the Associated Press that warm air is less dense than cold air so it rises, releasing the moisture and forming a cloud that lifts and ends up a thunderstorm started by fire.​
“These can be deadly, dangerous, erratic and unpredictable,” Flannigan told the AP.​
The storms can inject particles as high as 10 miles into the air and generate dry lightning. The rising air also can cause intense updrafts that suck in air at a rate to cause strong winds to develop.​
Sometimes those winds can create what's known as a "fire tornado," when winds created by an intense fire whirl and twist tightly. The hotter the fire, the faster the air rises and the tighter it twists until it takes off as a tornado. A fire tornado with the power of an EF-3 tornado was reported in the Carr Fire in California in 2018.​
Last week, an RFS firefighter was killed when a fire tornado caused by a pyrocumulonimbus cloud formation collapsing caused his fire truck to roll over, according to Reuters.​
“That extraordinary event resulted in cyclonic-type base flipping over a 10-ton truck. That is the volatility and danger that exists,” NSW RFS commissioner Shane Fitzsimmons told reporters last week on how dangerous fire-induced weather patterns can be.​

I wonder how many of those fires were set by terrorists?

The Australian PM is worthless and they need to kick his ass to the curb. He went on a vacation and let things get out of control. The dummy should have taken immediate action and called out the military to help put out the first blazes. But, then again, the Aussies will only let certain people put out fires that are burning everything in the country.

From WSJ:
SYDNEY—Wildfires ravaging much of southeastern Australia burned so hot that they created their own thunderstorms and lightning—similar to conditions during a volcanic eruption or atomic bomb blast.

Firefighter Michael Brearley was leading the defense of Wingello, a small town around 100 miles south of Sydney, when a huge cloud began to form in the distance on Saturday. He knew it was bad news: The area had barely seen a drop of rain for weeks.
Instead it was fire that rained down from the formation of pyrocumulonimbus clouds—created by intense heat driving air rapidly upward in the smoke plume from a wildfire, drawing in moisture and resulting in thunderstorms. Scientists say they are only beginning to understand the weather phenomenon, making its behavior hard to predict.
Pyrocumulonimbus clouds produce intense updrafts that suck in so much air that strong winds develop, which can cause a fire to burn hotter and spread, the Australian Bureau of Meteorology said on its website. The clouds can make nearby fires shift direction, and throw off embers that land several miles away from the main front, starting new blazes.

On New Year’s Eve, cyclonic-type winds whipped up at the base of a blaze in Jingellic in New South Wales overturned a 10-ton firetruck and another vehicle.

From The Telegraph:

At least 25,000 koalas are believed to have died in a horrific wildfire in South Australia that may have devastating consequences for the survival of the species.
The fire on Kangaroo Island, which was considered a koala safe-haven because its population had escaped a devastating chlamydia epidemic, was described as “virtually unstoppable” on Saturday by firefighters.
Footage filmed by an ABC cameraman in New South Wales on Sunday showed the charred corpses of hundreds of kangaroos and sheep lying by the roadside.

“Sorry to share these images near Batlow, NSW. It’s completely heartbreaking. Worst thing I’ve seen. Story must be told,” he said on Twitter.
The PM is being blamed. Scott Morrison, the Australian prime minister, defended his handling of the wildfire crisis on Sunday, saying “blame doesn't help anybody at this time and over-analysis of these things is not a productive exercise". (Is he related to Trump?)

A growing number of climatologists believe the pace of climate change has been underestimated.

What will it take for deniers to see: if our Earth's climate became hostile, where would you go? It's an elementary question and yet, I think a great many people have never considered it.

Right wingers only care about money. They think that will save them.

Clearing my throat! In order for a great many people to consider the endgame they would be required to THINK for themselves, read/research and this is not allowed in Trumplandia.

Few thought it would arrive so quickly. Now we’re facing consequences once viewed as fringe scenarios.
