WDS (ASX) Climate Action Now

@walbrook

Thanks for engaging politely, you dont often see good debate these days.

"Climate catastrophists, all those who live in fear that we are going to cook and the world is going to end, all those who follow the pronouncements of Greta Thunberg."

I think you and I would agree that there is a difference between genuine climate (and other) scientists and these "Climate catastrophists" you speak of. There are plenty of people from all walks of life that do harm when exaggerating scientific findings or even just make up claims without backing them with some evidence.
For what its worth, I dont think we are going to cook, or that the world will end, nor do I pay any attention to Greta, or other media folk (celebrities, the print media, the news etc etc). So, I am with you on this point.

"Nobody is denying that it is warming, it has been warming since the little ice age ended in 1680, the industrial revolution and the increase in CO2 began at 1850.Sure, CO2 is a greenhouse gas that contributes to the warming, how much is natural variation and how much is from CO2, there were no suvs or increased CO2 that caused the medieval warm or the Roman warm."

Again, mostly in agreement.
This video (same youtuber from the above videos) Does a really good job of going through what the scientific literature says about the medieval warm period.

"The claims about increased wild weather, fires etc are contradicted by the data, in fact cyclones are becoming less frequent, fires have reduced in most countries, deaths from weather related events have reduced, those record temperatures from the passed still stand, as do flooding events etc."

I think its important to note a few things regarding impacts of severe weather. Firstly, our advancements in technology allow us to communicate and warn people of extreme weather. We have stronger infrastructure, and better health facilities.

With cyclones, I found data that shows that at best, the number of cyclones is about the same over the last 50 years

I cant seem to find an open access link, but there's also this (https://www.science.org/doi/10.1126/science.1060040) which appears to show that hurricanes and cyclones that do form will tend to be stronger.

As you have previously accepted, we are definitively seeing more warmer days.

As mentioned above, we have better technology today than we did 30/50/70/100 year ago with regards to fired etc.

Yes, those single extreme warm dates from the past are still standing, but remember that just because a single day record (lets take for example the absolute warmest day on you image from the other day of 50.7C) might still stand, doesn't mean that there is no concern for the warming. A bunch of those records are from the 2000's and 2010's. There are also plenty of records from the 80's and 90's, which again, as you've agreed, the warming started much earlier anyway.

"Professor Richard Lindzen claims that contrary to the claims that warming will see an increase in wild weather it will lead to milder weather due to reduced barometric pressure differences as the cold regions of the world warm. This is what we are actually seeing."

I'd need to see what paper this is referencing.

"How much are we actually warming?80 to 90% of the weather stations in the UK and the USA and to some extent Australia are in unsuitable sites that are affected by the Urban heat island effect and so many of the charts are manipulated to exaggerate the warming, only the satellite chart appears to be reliable in my opinion'"

Well, at least according to the BOM

I am not familiar with the UK or USA, but if you can show me sources, I'd be happy to look.

With regards to how much warming we're likely to see?
Well, according to this paper (https://www.nature.com/articles/ngeo337)
We're likely to see anywhere between 2 - 4 C with a doubling of CO2 from pre industrial times. (so from say 280ppm to 560pm?).
