Is it unusual to have this sort of heat in the first week of September?
90:15
No, not at all.
90:16
No, it's just one of those ones where the cycles, where we are in the cycles and sometimes a little bit below average, but sometimes a bit more.
90:24
And certainly at the beginning of the month with surprises because we're acclimatized to the winter.
90:28
That's the big factor also is that we've been acclimatized to some shifts in cool weather.
90:33
Next thing, bang,
91:19
What about the rest of September and into October before we get to the summer?
91:24
Well, October's probably going to be above average in relation to temperatures because it's going to be a dry month.
79:17
But are you treated as a pariah by the forecasting business in Australia or do they just accept that... you're right more often than they are.
79:28
Well, that's true.
79:29
I mean, like, you have to have that reputation in relation to accuracy.
79:35
So you have to have above average accuracy and people will support you.
79:40
At the same time, a lot of people scoff at it because you're not within the realms of climate change, et cetera, et cetera.
79:47
But, you know, you just keep soldering away.
79:49
That's what I do.
82:07
Does that accord with La Nina or El Nino? I think we've spoken about it before, but where do you fall on the observations of those two characters?
1:30
But are you treated as a pariah by the forecasting business in Australia or do they just accept that... you're right more often than they are.
1:42
Well, that's true.
1:43
I mean, like, you have to have that reputation in relation to accuracy.
1:48
So you have to have above average accuracy and people will support you.
1:53
At the same time, a lot of people scoff at it because you're not within the realms of climate change, et cetera, et cetera.
2:00
But, you know, you just keep soldering away.
2:02
That's what I do.
4:20
Does that accord with La Nina or El Nino? I think we've spoken about it before, but where do you fall on the observations of those two characters?
88:53
Yes, and for listeners who don't know, you do your weather forecasting based on your sunspot activity, do you not?
89:00
That's right, sunspot, solar flares.
89:01
So when the sun is active, we get quite intense and extreme weather conditions.
89:08
And then when the sun goes into a dormant stage and where there's low sunspot activity, we get drought conditions.
89:14
And we're certainly seeing that in the last two to three years.
89:16
We're going through a sunspot maximum whereby we get increased rainfall, increased hurricanes, typhoons, et cetera, et cetera, which there's a lot on the way for the balance of the year.
89:27
And when the sun increases or intensifies, we get extreme weather and that's what happens.
90:02
We
114:19
In
114:19
this way, we utilize stem cells from a patient.
114:24
And over the past, let's say, 20 years, we came up with a new technology that we call a mini heart.
114:31
Now, this mini heart contains cells from a patient, and in this way do not require any immunosuppression similar to a heart transplant.
114:41
Then we take this technology to another level, and we 3D printed the mini heart similar to Lego bricks.
114:48
Now, this is a very multidisciplinary effort across the Heart Research Institute and the University of Technology Sydney.
116:00
So how many years has that taken to perfect? And I'm assuming, is it available now or still in development?
116:08
Well, we are taking any possible step to make sure it's safe before it's provided to the clinic.
109:30
I mean, that is unseasonal for June, isn't it?
109:34
Well, certainly it's like a blanket over the top of New South Wales.
109:37
So when that blanket's over the top, the heat stays in.
109:41
So I believe that June, the temperature will be above average, but there will be some snippets when the troughs move through.
109:48
After the troughs move through, you'll get that cold westerly wind on its way.
109:51
So that'll make the temperatures drop.
109:53
So for the time being, it'll be above average.
112:05
Are we in for a hot one, which would be allegedly on the back of an El Nino, wouldn't it?
3:03
Where do you sit on the El Nino, La Nina spectrum?
3:08
i don't sit there at all i use sunspot activity and that's the way the forecasting weather should be done and that's the only way you can forecast the weather because the sun changes within a 24 to 48 hour period and then we'll get inundated with solar activity and we get extreme weather conditions we went back we're going back to 2024 we're supposed to be a super el nino for the spring and look what happened there It was a dud, and they're talking about another El Nino in relation to the winter period ahead and months ahead, and I'm completely the opposite, and look what's already turning up.
3:43
So I question that.
3:44
Okay.
5:28
What do you see for winter temperatures around the place?
5:31
Well, I believe it'll be a mixed bag, particularly in New South Wales.
5:35
I mean, with this rainfall, we'll probably have above average temperatures and minimum temperatures because there'll be a blanket over the top of the New South Wales holding the heat in.
5:43
But then once those troughs do move, you will get some cold snippets.
85:59
Where do you sit on the El Nino, La Nina spectrum?
86:05
I don't sit there at all.
86:06
I use sunspot activity and that's the way the forecasting weather should be done.
86:10
And that's the only way you can forecast the weather because the sun changes within a 24 to 48 hour period and then we'll get inundated with solar activity and we get extreme weather conditions.
86:21
We went back, we're going back to 2024, there's supposed to be a super El Nino for the spring and look what happened there.
86:29
It was a dud, and they're talking about another El Nino in relation to the winter period ahead and months ahead, and I'm completely the opposite, and look what's already turning up.
86:39
So I question that.
88:25
What do you see for winter temperatures around the place?
