CF has always been a site that welcomes people from different backgrounds and beliefs to participate in discussion and even debate. That is the nature of its ministry. In view of recent events emotions are running very high. We need to remind people of some basic principles in debating on this site. We need to be civil when we express differences in opinion. No personal attacks. Avoid you, your statements. Don't characterize an entire political party with comparisons to Fascism or Communism or other extreme movements that committed atrocities. CF is not the place for broad brush or blanket statements about groups and political parties. Put the broad brushes and blankets away when you come to CF, better yet, put them in the incinerator. Debate had no place for them. We need to remember that people that commit acts of violence represent themselves or a small extreme faction.

Awesome! You can only do what you can afford at the time. As I said above, the Energy Transition will take 25 years or so even IF crazy climate deniers like Trump are all kicked out of government.
Of course - and it feels awful.
I thought of renaming my blog "The Lazy Environmentalist" because I feel exactly this guilt - and wish society could fix umpteen systems I am currently forced to use. I have a LOT of technical hope in various answers emerging - and listen to way too many podcasts about this stuff.
I agree! At first, when the global population and coal use were both so much smaller, the move to coal was a net environmental gain! It was a more energy dense source of heat than firewood - and it let the forests regrow!
But once we got to say the 1950's I wish society had moved into nuclear big time - until we had developed modern renewables. Fossil fuels would have been a great source of chemical feedstocks for many millennia if we had avoided just BURNING them all as fast as we did.
(There are new nuclear reactor designs that can burn nuclear waste! They're called breeder reactors, and they burn through all the extra energy that keeps nuclear waste radioactive for 100,000 years. By the time waste has been through the breeder a few times, it's so "hot" it burns itself back to safe levels in just 300 years. Great idea - but unfortunately way too expensive. Renewables are faster and safer and going to be VASTLY cheaper!)
Exactly! I wish I could believe climate change was all a government hoax to get us to give up fossil fuels before they peaked! Most people have no idea that running OUT isn't the issue, but the moment when they start to RUN DOWN could trigger an economic catastrophe if we didn't have renewables and EV's scaled up to the lower costs we have today!
Hydrogen could in large harvesters and airlines. But keep in mind hydrogen takes 3 or 4 times as much energy to make the fuel as it does to just charge an EV in the first place. Also - as you know, Aussie trucks are INSANE! America has something like a 36 tonne limit on their trucks - but we have huge trucks. There's no way a Tesla semi could pull our loads! So what to do?
Easy! I'm so proud of this company! They're Aussie - with big trucks - so they invented a BATTERY SWAP program for giant trucks!

Goodness!
Oh yeah! Now you're speaking my language. My sister-in-law has a Phd in this stuff - and I have my own hobby blog about it.
Amen brother.
He doesn't fix many of our self-induced problems. As Romans 1 suggests - he lets us experience the results. He hands us over to them!

Heating up down under

When I posted the original OP about high temperatures in NW Australia, I didn't expect it to devolve into two competing camps regarding climate change.
But before I get into my own thoughts, I'll add a bit more news about record October temperatures in two capital cities - Adelaide and Melbourne.

On climate change, I think it's happening. For our part we do a limited amount - we've got a small array of solar panels which we've kept below a certain threshold as we lose the government subsidy if we exceed a certain amount. We still generate more power than we use in general consumption, excluding hot water. The subsidy finishes in 2028 so then we'll have to think about expanding the system and maybe getting a battery.
We have a "Heat pump" HWS (like having an air conditioner bolted on top of the system), we have one hybrid vehicle (petrol or "gas" as in the US) while the older vehicle is petrol only; we have a water tank which doesn't save much water as it is only used for the gardens, a magnetic induction stove to use less power when cooking etc.
But we still create our fair share of CO2, produce heat when we do anything at all; we use less water than the average but we still use water; we try to recycle what we can (it is amazing how much packaging has to be recycled - there must be a significant energy component in doing that); and overall we live in a wasteful society with thousands of cars in peak hours just pouring CO2 into the air and going nowhere.
I think God is going to hold us to account for our incredibly wasteful lifestyles. I believe he put the fossil fuels there and that they were intended to last for centuries. He didn't put them there so we could burn them up in a century or so with our short sighted greed.
And they are running out, so alternatives have to be found whether we like it or not.
For myself I think hydrogen will play a significant part in any future energy system, especially transport. But the infrastructure isn't there, and there is the energy component required to isolate it and store it under very high pressure.
In a Toyota Mirai hydrogen car, the pressure in the tank is about 10,000 psi, or 5 US tons to the square inch. I used to think Scuba tanks had a lot of pressure at about 3000 psi, but hydrogen fuel tanks are more than 3 times as much.
Our cities are designed for independent transport and we all assume we can drive wherever we want, whenever we want. I think a sea change is required in city planning.
In a nutshell, I think climate change is happening and I also think God is going to hold us accountable for our wasteful lifestyles which are exacerbating the problem. He won't fix it either - His attitude will be "You made your bed. You lie on it."

Two of Australia's capital cities on track for warmest October on record
Unseasonable temperatures have lasted along the eastern seaboard for weeks — which has Sydney, and possibly Brisbane, on track to observe their warmest October on record.
