Up until the point where it *does* and it's way too late.

 

Honestly, as I mentioned in the Covid thread, the response to that has really shook me on terms of confidence regarding humanity actually being able to deal with such future crises.

I know we’ve all seen this before but it really is so apt

I get it that people have been locked down or restricted over last 2 years. Therefore they want to go abroad for hols etc. Still a valid argument for sake of climate change are people still flying too much ?

I could dig out some stats to back me up on this, but from what I can tell aviation is actually a reasonably small contributor to carbon emissions and therefore climate change, especially when compared with power generation which is by far the biggest elephant in the room.

 

We should certainly be looking to make all forms of transport more eco-friendly, but it's switching out from practically all kinds of fossil fuels worldwide that is probably the priority here.

From memory, it accounts for around 2% of annual C02 emissions and around 10% within transport overall...road going vehicles being 74%.

 

In terms of pollution, the relative amount of exhaust emissions depends upon combustor temperature and pressure, fuel to air ratio and the extent to which fuel is atomised and mixed with inlet air. 3.5% of the world's emissions (which is the part aviation fuel plays) is by far the most efficiently combusted. And of the remaining 96.5%...all those trucks, cars, ships, trains and tankers - all that heavy industry and urban/household consumption?

I do think it must be awful in a very busy inner city area such as London for the health of children and elderly. I look forward to much cleaner transport and perhaps less use of cars for very small journeys

I was born and partially raised there, but to spend a lifetime in certain parts of the city is without doubt one of lower expectancy.

This is a difficult problem to solve. How do you balance freedom of thought and speech with the consequences that freedom invariably results in, given nature doesn't care about anything other than facts?

 

Perhaps a surgical approach is called for regarding individual or small group purveyors of misinformation, but then that has issues of its own.

Imagine we would all love to have an altruistic single point of truth we could rely on, but come on, it’s never going to happen due to human nature. 
 

Just feel that the current system of trust being down to the individual, and the individuals desire to best educate themselves (Against which modern cynicism will forever rage) is pretty close to as good as it gets.

For those interested in such things, the RHI (renewable heat incentive scheme) ends at the end of March, but it is being replaced by the Boiler Upgrade Scheme.

Difference being that the RHI paid out 7k over 7 years when you purchased a renewable/emission friendly system, whereas the BUS pays out a flat 5k upfront on the same system type upgrades.

 

Approximately like this anyway. lol

Then I am sorry, but given the recent track record of the world on managing global crises, our current best isn't good enough and the Earth will in due course punish us for that failure in typical evolutionary fashion.

 

Speaking personally, I'd rather not have that happen for a while yet.

I've been corrupted by TV. See tahiti, automatic "it's a magical place" smh. 

 

Seems true in this instance though. 

That it does, considering how long it takes coral to grow and mature.

 

TBH this also reinforces the message that Carlin said all that time ago, if the shit hits the fan: "the planet's fine, the people are fvcked."

Well, if it breaks down it'll more than likely cause fatalities I'd imagine.

Ah yes, absolutely - something like that failing would be much more potentially fatal than a car on the road doing so.

 

However, I would hope that such things would be accounted for in the form of a lot of redundant systems and safety measures to make them as safe as road cars are today before they're even close to available for use by the public.

Really hope that flying cars/other vehicles won't be a thing.

Why?

* Roads, especially motorways no longer needed

* Potential for reduction of accidents

* Serendipitous discovery of places is increased
