1. If it exists, and we do something about it, we win.
2. If it exists, and we don't do anything about it, then we lose.
3. If it doesn't exist, and we don't do anything about it then we lose nothing (a win, in effect).
4. If it doesn't exist, and we do something that we think will "help" then we lose nothing (again, a win).
Best then to avoid 2 and do what we can. At worst we are no worse off than now, at best, we save ourselves a lot of insurmountable problems down the line.
Of course, some people will say "I want my big inefficient car, and my inefficient house etc., so please go away sexually". Others will say, doing somethinjg doesn't hurt me so I'll tag along. Others will want to do something because it's trendy. Yet others because it's the right thing to do.
I don't have children, neither does my sister. My genetic line dies with me so I don't, effectively, give a stuff what happens to the planet in, say 50 years. On that basis, I can burn every drop of oil, burn every lump of coal, fell every rainforest tree. What do I care?
Mankind is investing a countless amount of money because of global warming, and if it turns out to be bullshit, all that money will have gone to waste.
Not to mention the catastrophic effects of lithium mining. Great for the environment...
As I pointed out, new wind is/will be subsidy free. Because the turbines are getting bigger the cost of maintenance per MWh is getting cheaper so costs are coming down, unlike all other sources of power. We had a wind farm in the Bristol channel near me turned down for planning because of aesthetics, yet they same people are happy for thousands of static caravans to litter the countryside. Really gets my hackles up.Big Tea wrote: ↑30 Jun 2018, 11:44I agree with the principle of wind and solar, and they should be pursued to the (reasonable) maximum.
However, in UK at least it has passed into politics and people making money from government grants for instillation and the government being able to point to figure which are completely disconnected from reality seem to have become more important than the actual reason for it.
Also, no one seems to factor in the resource cost of building installing and maintaining, then disposing of all this new tec. or having to have a stand by for when it is dark with on wind.
While I am fully for it, it has taken on a headline life of its own rather than being an included element in the national grid.
Politicians, business profit and headline grabbers have hijacked what should have been handled by expert planners.
And I mean experts, not of the sort we usually get trotted out to tell us how good the government and the pressure groups are doing.
Edit,
As an incidental to this, from my upstairs windows I can see 3 25mw wind farms and several small installations, and know that out of sight that area are 3 medium size solar farms.
I have no problem with seeing them and find them far preferable to what I saw through my window when I was a kid, which was plumes of smoke everywhere.
Tin hat time -- that's because not enough people are buying beer or coke, so they're using it as a means to limit supply and hike up the prices don't tell big CO2 we're on to themBig Tea wrote: ↑30 Jun 2018, 12:16Would you believe the British press are now thumping on about a 'Co2 shortage'

Very true, if that´s the case we´d be wasting huge amounts of money.DiogoBrand wrote: ↑30 Jun 2018, 05:31Except that if we do something about it, we also lose.

But we will always have tides* and we can predict them to the minute many months in advance.

Some people perfectly represented by Trump, have been denying climate change for decades. Once they´ve been told that´s not debatable, they switched to ok ok it´s real, but it´s not our fault
Anything to ignore our responsability and continue prioritizing economics over anything else
The UK is very small compared to US, Russia and China. 30% of a tiny nation isn't impressive.jjn9128 wrote: ↑30 Jun 2018, 11:17Wind and solar currently account for ~30% of the energy on the national grid in the UK. New wind farms are government subsidy free and are selling energy at ever lower prices (£45/MWh and continuing to get cheaper as turbines get more efficient and require less maintenance per MWh produced) - unlike Hinkley C which is costing the UK taxpayer billions in subsidies, as well as selling electricity way over current wholesale (£93/MWh) with all the money going to the French and Chinese. Energy companies are investing in wind because they can make money back. I don't know how other countries are doing but the UK as an island has more than enough potential off shore to make most of out electricity from wind farms, if we can sort out tidal we'd be close to 100% from renewable.

I do. I also understand that those aren't helping much.

Let's turn it around - you claimed the Earth is getting closer to the Sun by "falling down the gravity well". Care to share the mathematics of that with us?
You are the one claiming that Earths orbit is powerful enough to escape the deepest gravitational well in our Galaxy, without adding more energy to the system. Like water flowing up a drain.A gravity well or gravitational well is a conceptual model of the gravitational field surrounding a body in space – the more massive the body, the deeper and more extensive the gravity well associated with it. The Sun is very massive, relative to other bodies in the Solar System, so the corresponding gravity well that surrounds it appears "deep" and far-reaching. The gravity wells of asteroids and small moons, conversely, are often depicted as very shallow. Anything on the surface of a planet or moon is considered to be at the bottom of that celestial body's gravity well, and so escaping the effects of gravity from such a planet or moon (to enter outer space) is sometimes called "climbing out of the gravity well". The deeper a gravity well is, the more energy any space-bound "climber" must use to escape it.
Sounds like magic. Just like the rest of climate change.Just_a_fan wrote: ↑30 Jun 2018, 15:08Go look up tidal acceleration of planets etc. The tidal effect between the Sun and Earth results in a reduction of the Earth's spinning angular momentum and a transfer of that energy to the planet's orbital angular momentum. An increase in orbital angular momentum means the planet "speeds up" and so occupies an increasingly distant orbit. The effect is ridiculously slow, of course, hence why we are moving away from the Sun at about 3m in half a million years.
Suffice to say, the Earth is not "falling down the Sun's gravity well".
Just for accuracy our Sun is a long way from being the most massive object in our galaxy.Zynerji wrote: ↑30 Jun 2018, 14:13Why should I? I started as the skeptic.Just_a_fan wrote: ↑30 Jun 2018, 10:37It's exactly the same process that is causing the Moon to slowly move away from the Earth.

That just sounds awful coming from engineering types...
