It’s definitely ammunition, deservedly so. This sort of misrepresentation is par for the course. “The world is ending in 12 years.” I seem to hear that every 12 years just when people have forgotten about how the world was supposed to have been flooded already. Activists seem to have a ha but if exagération, if not downright lying.

Can't we make solar powered ice makers on a huge scale and just re freeze it?

What you really need is a way to turn heat into some sort of long term energy storage.

What you'd need is something like a thermal->chemical energy converter. You could even make it do something useful, like desalinate water.

However, good luck pulling enough thermal energy from the air or ocean to have any significant effect on global climate.

If you're interested in getting involved in addressing climate change, here are two options for citizens to get involved: 1) The Citizens Climate Climate Lobby has been around ten years, and it currently has a bill in Congress that has bipartisan (1 Republican) support: The Energy Innovation and Carbon Dividend Act ( http://energyinnovationact.org/ ). With this plan, all the revenue from a carbon tax* is directly ret…

Please read the IPCC reports, not ... whatever your current source is.

Are humans advanced enough to engineer around sea rise and temperature changes?

Yes.

But not while maintaining anything like current first-world culture. You either need to reduce energy consumption significantly or reduce population significantly.

Two guesses how that plays out.

Earlier quoted context omitted.

I have no idea if that’s possible, what I mean is we should stop trying to get the US and China to agree on anything let alone climate change so we need grand silver bullet solutions.

China does accept the reality of climate change and is enacting policies against it. It might not be nearly enough but it's not fair to lump them with the USA on this one.

80%+ of the plastic in the ocean comes from China. It's not fair to lump the US in with China.

"They recognize it and want to do something" doesn't mean shit when you're by far the worst part of the problem. Especially when "wanting to do something about it" and "doing something about it" are ridiculously different things.

I think their position is: 1) don't shut don't existing nuclear plants to replace them with fossil fuels and 2) wind and solar should make up the new energy mix. But for what it's worth, the membership has diverse views. I'm pro-nuclear.

CCL tends to be more pragmatic and have many more nuclear proponents.

Well, it advocated stopping travel by plane in favor of trains... which in terms of practically is almost literally insane. So, there was more wrong with it than just being anti-nuclear (which it was).

So how much was the actual global sea-level rise in the past 10 years and how does it relate to previous estimates?

Maybe something like this? http://news.bbc.co.uk/2/hi/science/nature/7139797.stm I don't doubt humans are affecting the climate. I do doubt that humans can extrapolate the effects of what they are doing out into the future very well.

That article describes one scientist's hypothesis based on an extreme year - another more conservative scientist is quoted also. The thing to pay attention to is peer reviewed consensus, which is still alarming.

We do it currently. Holland is a good example of fighting back the sea, but at great expense. And not every country will be able to do this type of engineering.

The temp rises are another thing that we can adapt to. Maybe even some global engineering to thwart it. But again it will be at great cost. And this will probably have the bigger impact on all of us. Our eco-system is very susceptible to small temp changes.
