So after decades of waste they started to improve the system. Maybe you should allow solar and wind similar timelines.

notsureifserious.jpgAustralia's first LNG train came online in 1989.
The photovoltaic effect was first discovered in 1839 and the first solar cell was built in 1883. The first windmill for electricity was constructed in 1887. Before that windmills used for mechanical power had been used since the 7th century.

Two-thirds of green energy projects in Great Britain fail to clear planning stage
Speculative applications for renewables schemes are slowing clean electricity transition, study finds

I reckon where I live is a pretty good example of it. 98% of power generated is from renewable sources. Mostly hydro. Cheap and efficient.
You get a weird dynamic on the roads though. Combination of Teslas and RAMs.

Great to hear about successful projects. Here's some other brilliant examples.

Hail cripples massive solar farm, sparking resident concern about vulnerable 'green' tech
A major hail storm near Houston knocked out large parts of a major solar farm, sparking energy reliability and chemical exposure concerns among nearby residents.

Plus how much of the planet has been harvested for "green" energy.

Yep and the cost of recycling lithium batteries that have stopped working or had their working capacity degraded after 200-300 cycles is more than what it costs to mine new lithium.
Thankfully sodium ion batteries (which can use the byproducts from seawater desalinisation plants) should replace them eventually.

How much has the climate been mitigated so far? When should we see a difference? Fewer fires, floods, storms and all that?

I was alive in the 80s but not not old enough to remember what was happening at the time.
I remember learning about the ozone layer at school in the 90s and how CFCs are bad so we don't use them any more. Overall climate change is a bit more nuanced than that but it I can't see the world agreeing on something like that today.

Climate change will never be mitigated.
Global population is forecast to increase another 2 billion before it levels off in another 50 or 60 years. Humans just don't seem capable of doing anything sustainably.
Everyone driving around in an Elonwagen will have some benefits but definite drawbacks.

So why are we bothering?Climate change will never be mitigated.
Global population is forecast to increase another 2 billion before it levels off in another 50 or 60 years. Humans just don't seem capable of doing anything sustainably.

I knows it’s got nothing to do with money.

Because humans care about the survival of the species. More accurately survival of some of the species.
The climate is the climate. There is a reason 27m people live in Australia and almost none of them occupy 90% of the land mass. When people say 'the ice caps are melting!' do they care about Antarctica? No, they care about the impact of rising sea levels on them.
When people talk about climate change (which is very real) they generally just mean climate change impacting human activity. Perth average rainfall since records were kept is 844mm a year. From 1994-2019 it's 727. The last two years have been 613 and 596. Hotter, drier. Twice as many people trying to live off 250mm less rainfall than 30 years ago. More land clearing, more groundwater being drawn from aquifers, two desal plants, more energy consumption, poorer air quality etc.
That is just one city and just some things specific to that city. If Perth was still 1m people it would still ne hotter and drier than 30 years ago because the climate is impacted by global factors. But humans fundamentally just keep expanding in number, expanding in territory, consuming resources etc.

So you’re saying Australia’s renewables strategy will reverse these changes? Or does there need to be a drastic reduction in the world population as well. If so, how would this be achieved and how long would it take? War? Disease? Who decides?

Australia's domestic renewables strategy won't make much of a change to global anything. Unless we stop selling coal and gas to other people to burn. A bit like owning an electric car then charging it from coal fired power you aren't really fixing the problem.
If you mine iron ore in WA then ship it to Japan to be made into steel using coal from Queensland then ship it back then whoever you attribute the CO2 emissions to throughout the supply chain they still go into the atmosphere. People get hung up on per capita emissions. Either total emissions start going down or they don't. Currently they are still going up.
Norway, who all the champagne socialists love, has 98% renewable energy generation through mostly hydro. Great, but Equinor is still a major player in the global oil and gas industry and are still exploring and developing new projects. All of the nation's wealth has been derived from fossil fuel exports. They don't have much of a manufacturing sector so import consumer goods, vehicles, food, all sorts. And all these things are manufactured elsewhere and shipped there.
A drastic reduction in the world population will likely only ever happen due to climate change. The planet will adapt with or without humans. How humans adapt remains to be seen.

The effect of land clearing for our urban sprawl is probably responsible more than anything. When you remove trees and vegetation to the extent we have, it has a profound effect on the water cycle due to transpiration losses.
The Effects of Deforestation
Deforestation accelerates climate change, harms biodiversity, and disrupts ecosystems and economies, making its impact a critical global issue.

One problem is the prospect of a new way to make money, via renewables projects subsidies, attracts grifters who don’t care about the planet, or communities, or what happens to the projects after they are completed. Hence failures are common, eg green hydrogen.
Small modular nuclear plants make the most sense in this vast country, even if expensive as alleged. We have to start sometime.
You’re never going to get the whole world caring about the future of the planet; people everywhere don’t want their living standards falling, quite the opposite. Fossil fuels have brought unprecedented wealth to the world. Food is more plentiful than ever before.
It makes no sense to impoverish ourselves through nobly closing down the source of our country’s income, that pays for just about everything that makes our lives comfortable. What would replace mining exports?
