For the last 2 months it seems Perth has been freezing.

May and June have average max temperatures of 22.3 and 19.5 yet nearly every day it seems the max has been around 17C.

No let up in sight for the next week also.

Global Warming it seems also causes significant cooling.

We should all do our part to reduce our carbon emissions.

15 minute cities with carbon credits points for each individual. Seems like a good idea on the face of it.

Any takers?

Any concerns?

Huh?

Don't worry about PC. He thinks global warming should mean everything gets hotter. He doesn't understand that can some times mean things get colder.
The reversal of warming ocean currents, caused by ice at the poles melting is an example.

The mean temp for May 2023 was 22.4.

Unfortunately, the scientists that coined the term are very poor marketers IMO, and have confused the public. They should have called it Global Climate Instability, because this is the effect people see in real life.

10 thousand years ago my ancestors walked to Tasmania ! Think about it

All of them, or just some of them?

Where were the rest of them at this time?

Is this factual or just a guess? Even with lower sea levels some places were still islands. I can understand boating across from New Guinea and the rest of Asia, but was there a land bridge to Tasmania at that time?

It is interesting to see Polynesian history and how they spread out across islands that you would assume are bloody impossible to find in small boats, but they obviously did it.

All their predictions of sea level rise from the nineties have turned out to be complete horse ....

Never mind the flock keep still believing

See no sea level rise.

Observation is no longer evidence.

All their previous predictions in sea level rise from the nineties have proved to be hogwash so why are to trust their future predictions?

According to the B O M Perth the average for this month is 1.7 C lower up until the 24th.

It looks like by the end of this month it will be over 2 C looking at the forecast for the coming week.

The earth cooling is also global warming

"Decile 9 maximum (or minimum) temperature (?C)
Monthly decile 9 (90th percentile) of maximum or minimum air temperature. The annual decile value must be calculated from yearly data, and cannot be obtained by adding together the monthly deciles. Decile values are used to give an indication of the spread of the observations over the period of record; in this case, daily observations within a month. To determine decile 9 of a series of observations, the data are first arranged in order from lowest to highest, and then divided into 10 equal groups. Decile 9 is the value at the top of the 9th grouping. Over the long term about one day in ten can be expected to have a (maximum or minimum) temperature exceed the decile 9 value."

I'll be dead by the time the earth is unlivable. Explain again why all us old timers should care?

So, having seen actual data, you retract your comment that last month was cooler than average?

I mentioned so far this month according to the B O M the average max for Perth up until the 24th of May is 1.7C cooler than average.

You conveniently chose not to respond to it as it goes against the narrative.

The earth if anything appears to be going through a cooling phase.

I don't have kids who play at the park. Explain again why I should pick up my dog's excrement?

Im glad you used dog **** in reference to Hansen's claims thats what they are.Media headline grabbing for personal gain.
You pick up dog **** because its real a prediction is not .
I hope your dog is vegan.

Given the interest in Perth June temperatures I thought I would have a look at the historical record for Perth regional office. Notice a trend?

1881 1910 17.6
1891 1920 17.7
1901 1930 17.9
1911 1940 18.0
1921 1950 18.3
1931 1960 18.2
1941 1970 18.4
1951 1980 18.5
1961 1990 19.0
1971 2000 19.2
1981 2010 19.3

Is it reasonable to use a polynomial fit to forecast, and particularly to forecast forward well beyond the spread of data ?

Or should you only use polynomial fit to estimate a missing value that falls within the bounds of the data ?


I mean, if I try to retro fit whatever formula you used to get that forecast (one might call it a "hockey stick" graph !!) then it means if you go backwards, the mean temperature in Perth region in the year 1500 was above 30 degrees. And it was hotter than today back in about 1700, before dipping to a minimum around 1900.

If you fit a third order polynomial to the data, then back in 1700 the average temperature in Perth was apparently -1 deg. Mmmmm, must have been the infamous WA ice-age written into all the geological records. The indigenous-eskimo era was it ?

Hope you are not making the same mistakes that Mann did.

Using the above sea level graph, sea level will increase 1m in the next 300 years.

Seems manageable and a long way from an 'emergency'.

All for pumping less crap into the air and the ground (and sea) but I am completely over the constant barrage on a daily basis of GW blah blah blah.

A great industry to be in I'm sure and pays well to those who play.

Where is the weather station located? It could be a heat island effect. 120 years ago Perth was not as built up as it is today. There was probably a lot more bush and less concrete and asphalt compared to today. It would be better to measure the temperature at a location that has not seen a lot of development over time.
