Dim The Sun

[JBR]

While that is absolutely true I don't think the plans involve any lagging.

No, I think they are talking about making clouds more reflective.  From what I hear, the Labour party's policies are all based on unachievable bright ideas!

It's all peeing in the wind.

To expand/grow markets, one needs more people who will buy, sell and make things.  This requires more energy, more materials, more food etc.

I'm sure that we can all see where this is leading and the only thing anyone can do is to slow down the rate of expansion.

Referring to house insulation, I assume?  I agree.  It helps prevent heat going out and conversely prevents heat coming in.

I was referring to clouds actually although house insulation works the same.

Not certain about the last bit as I think the idea was to somehow produce a reflective layer to incoming visible light which wouldn't necessarily prevent the outward passage of IR in the way CO₂ does.

What I am certain of is that the cost of producing any worthwhile cooling would be huge as you say and there is always the chance of unintended consequences.

In my humble opinion and mad scheme of this type will make no difference to anything whatsoever, except possibly the account balance in some people's banks.

Yes increasing cloud cover keep in the heat at night - easily observable by anybody.

I agree it's a madcap scheme that is very unlikely to work. Far too many scientist these days have to mention climate change in their grant applications to get any money. That is why there seems to be a consensus that it is happening and can be ameliorated.

I'll believe that the climate is changing. I've lived long enough that I can see that even. What I am very dubious about is the cause being solely human CO₂ emissions - they won't help but I seriously doubt that they are the sole or even primary cause or that society can continue to advance or even just continue if we put a block on fossil fuel use because there is currently nothing in place that allows that to work. The variable nature of wind and solar just make fossil fuels even more necessary to fill the gaps.

The only thing I do disagree with is that anything that reflects back sunlight during the day (which is what I think they are testing) will cause a temerature increase overnight. I don't know what they are using and certainly don't know if it would have any effect on passing infra red but do think they would have checked that out before trying. The main reason I think it wont work is the huge scale needed and the high speed upper tropospheric jet stream quite apart from any pollution or other unintended consequences.

The scientists involved will be happy no doubt as they will be funded for another year or so while they dream up something else they can get paid to test once this one fails.

I completely agree.  Climate change is natural and has been happening for millions of years.
An incompetent Labour government will never overcome it, regardless of how many windmills they build!

Just heard mention of another couple of related things.

Apparently just as they plan to dim the sun they are going to insist on solar panels on all new build houses. That came at the same time another government policy is to ban the import of solar panels from China  with no plan on where all these newly required solar panels are supposed to be coming from as nowhere else produces the required quantities.

I agree with you about climate changes,  JBR.  
Just found this on google -

" In addition to the ongoing climate change we're experiencing today, Earth's history includes numerous periods of significant climate shifts, including glacial periods, ice ages, and warm periods. These changes have been driven by various factors like solar activity, volcanic eruptions, changes in Earth's orbit, and even evolutionary changes in life forms."

In our papers I also read about dimming the sun, but here they are testing other ways by renaturating the moors, protecting seaweed areas etc. In our region lately summers are hotter and snow is a rarity. When I was a child you could ski here, now only in some parts and only for a limited period. 
As to insulating houses, that's a special question - it's promoting mould sometimes and easily flammable. 
My son-in-law installed two solar cells on my balcony - so let's wait and see.

Yes, our political pygmies have also been talking about 'dimming the sun' - something about seeding the clouds to make them thicker and hold more rain!
They are also big supporters of windmills which, although they can generate electricity if the wind happens to be blowing, they cannot provide a reliable and constant source.
I still maintain that when the climate changes, as it has been doing for millions of years, you're not going to stop it!
