Really, a little blurry, it is not a movie, it is the education that is the content. Try listening to what he has to say. The images are not what is important. 90% of the time in a lecture all, I cannot see the blackboard.

Maybe you shouldn't disregard one of the best series of lectures on science ever if you are really interested in science.

I recently came across a paper Jones et al 2023, which cites increased temperatures per Gt of GHG's.

https://www.nature.com/articles/s41597-023-02041-1#Sec16

Excerpt - "According to our estimates, 2,471 Pg CO2 were emitted globally during 1851–2021 (Figs. 3, 4) leading to a CO2-induced increase in GMST of 1.11 °C (Fig. 5, Table 1)."

https://ourworldindata.org/co2-emissions


The usual calculation is Warming vs Cumulative CO2 emissions in Gtonne. To convert Pg to Gt multiply by 10.

So having done the necessary calculations, we come to the following -

So dividing the temperature change by the CO2 emissions data -

1.11ºC/24710 or 0.000045ºC/Gt Globally.

Australia's emissions are of course smaller.  In the order of 19.66Gt cumulative. So we multiply the global change per Gt by Australia's Cumulative emissions and we get 0.0008847ºC since 1850.

I didn't take out the start figure as it amounts to little more than a rounding error.

Now the fun part -

"The latest report from Net Zero Australia (University of Melbourne, the University of Queensland, Princeton University and management consultancies Nous and Evolved Energy) puts the cost at $1.5 trillion by the end of the decade, with the need for $7 trillion to $9 trillion of capital by 2060 to meet Australia’s aspiration of net zero by 2050."

$60 trillion to reach "Net Zero" for about 9 ten thousandsth of a degree change.

Cheap innit?

Another study citing the IPCC said the change was .0008ºC/GT

.0008*19.6 or 0.01568ºC. Still cheap innit?

I think inconel is used in exhaust systems for RX7 cars

Yes Lee. I've always believed that cities contribute the most heat

She's good.
Saw an older clip of hers blasting this sort of SCAM SCIENCE getting about.
The biggest SCAM going about at the moment is the Mars Colonisation to get $$$$.

Science used in motor vehicle engines.

Here is a fascinating video about rebuilding engines and the coatings used instead of cast iron cylinder sleeves.
It's also about the environment.
