No climate change if world embraced nuclear
But it is in development, and it is a consideration that the Australian government is working on also.
That doesn't mean new coal-fire energy-producing units won't implement what is available.
Andrew Bolt thinks depending on new technical developments are essentially "pie in the sky".
I am not convinced of that, personally.
No one is infallible. Not even me.
"Nothing ventured, nothing gained."
"A journey of a thousand miles begins with a single step."
28% of world CO2 emissions.
If the left were serious, they would pressure China into not polluting the earth.
Sic Greta on them propper.
Politics.
China have a major hydro-electric project which they plan to meet their 2030 targets

There'd be no climate change risk if we had fewer kids, lived closer to work (or worked closer to home) and stopped buying unnecessary s**t.
Not gonna happen, though, is it?
The smart money is on trying to develop renewables so they are genuinely self-perpetuating. Which means designs and materials that are easy to overhaul or, in time, recycle. It also means being smart about specialised energy generation across the globe. Solar panels in the desert, hydro schemes for mountain streams, wind turbines for the bits that blow.
At the same time we also need to cut consumption per head, AND ideally reduce the number of heads too.
It's rare that I agree with Pepe, but fewer people is really the only logical answer. We live on a planet with finite resources, the only thing we're continually getting as an extra is the rays of the sun. Well, and the odd meteorite, but they don't really help.
Nuclear is a short term vs long term trade off, which is why politicians love it so. It gets us out of trouble but then puts us at risk in other ways for thousands of years. Coal and oil are a slow, drip-feed death, nuclear is an all-or-nothing gamble. It's safe most of the time, the problem is that on the odd occasion when it's unsafe, it tends to do an awful lot of damage.
It would help if we could guarantee the safety of spent nuclear fuel, but that seems to rely quite heavily on a lack of armed conflict, and as a species we're particularly rubbish at being nice. The last Century, for example, wasn't entirely stable. Yet we think nuclear waste will be fine for much, much longer than that.
Come off it, anything could happen.
Personally, I would rather live a simple life - even down to sleeping when it gets dark, and working when it is light - than go further down the nuclear route. But I will be outvoted by people who want to play golf, holiday abroad, buy tat from all over the globe, pump out kids and drive some bloody great 6 wheel drive earth mover knob substitute.
And they'll be allowed to continue, because "Freedom to do as I bloody well please" is always the ultimate vote winner.
We're dipping very heavily into the ultra long term, overs and unders pot now. Making promises we can't keep, I suspect.
I feel very sorry for the generations ahead of us. And also a bit smug, as I don't have kids, so I won't have the guilt of knowing I've screwed my own kin over. That's a bit of a hollow victory though, TBH.
They certainly haven't done anything to reduce the carbon emissions from coal-fired plants, which is the most pressing concern related to their operation at the moment.
I don't believe that is true for *new* coal fire plants.
You burn coal, it produces carbon dioxide, right? There's discussion of implementing technology to sequester CO2 but nothing has been towards that goal beyond discussion.

You can't purify the carbon from coal, coal is carbon.
This explains many so-called clean coal technologies, although I would assume it has a pro-nuclear bias:

Capturing carbon dioxide and storing it long term is currently expensive and costs energy to do. I know researchers have been storing it in underground dry natural gas wells, but those can leak. If you lock it into a solid form, like limestone, then you have to still store it where it will not react. There is no simple fix other than using plants to gradually absorb it. Unfortunately we cannot grow enough plants to get the job done quickly in our lifetimes.
There are ways to get carbon dioxide to go backward towards carbon and oxygen without plants, but you need the right special catalyst to do so. A company is selling diamonds that they have synthesized using reclaimed carbon from carbon dioxide. They claim that they have a catalyst that works. The catch is that it is still electrically expensive to do (darn thermodynamics!). They are charging more than nature made diamonds per carat.

I remember reading somewhere that in five hundred million years the output of the sun will have increased ten percent. This will warm the oceans and cause so much carbon dioxide to dissolve in them that there will no longer be enough for the C3 photosynthetic pathway to operate. This will cause the extinction of 99 percent of all plants, and when that happens nearly all non bacterial life will follow.
This change is gradual and most likely slow enough for the nature to adapt.

Well it won't at least not complex life. By that point only bacteria will survive. We know an ecosystem of nothing but bacteria works because that's all you had for the first three and a half billion years of life.
Five hundred million years is a lot, even for complex life.
Five hundred million years ago was Cambrian - the beginning of complex life as we know it (in the ocean, no complex land organisms).
Sun intensity was changing through all this time.

Well we will all be too dead to.worry about it by then.
