Sorry, 100 GW would be only 5% of China energy needs. But still it is an impressive amount.

better start to buy land in area near coast which is 6 to 9 meters higher than coast line, soon you can sell them as "land in coast line" and if you go through the trouble building nice houses there, you are gonna make profit nicely.

In Italy firms started advertising homes on hillside saying "Soon you will be seaside".

10GW to 100GW of wind turbine power is an impressive level of installation. But, regarding such an investment as being able to provide all the electric requirements for large communities is fallacious.

Across the globe the average wind speed needed to produce power is 6 metres per second. These wind speeds are achieved "on average" for 30 days (max) in every 100. (NOTE: the wind speed is normally nearer 25 days than 30, but we will be generous).

So, what do the large communities do for more than two thirds of the year when the wind speed is insufficient to generate power? Sit in the dark, not doing things?

Obviously wind power and solar power cannot meet all energy needs of China and any other country, But there is also hydroelectric power (think of the Three Gorges Dam) and nuclear power. Since most of China electricity comes from coal burning, and its gaseous emissions, any source that eliminates some of those gases is welcome. Incidentally, Japan has launched today the Ibuki satellite for the monitoring of greenhouse gases emission from space, preceding NASA and its Orbital Carbon Observatory. Evidently also Japan shares the worries about global warming.

that is excellent option.

that is excellent option.

Reminder: a frequent result of sitting in the dark is a mini-baby boom about nine months later.

So that's why India and China are so far ahead of US, Dang. ;)

They're adding some wind farms near us and I fully support it.

We've a Solar Plant near here, I hear in the Summer It really cooks too.

Solar Thermal Power Stations List, The 1st was Solar One which was converted into Solar two and It's a 10MW Plant.


Solar Two near Barstow CA in Daggett CA
(And relatively near Yermo, Just farther away from Daggett up the road so to speak and somewhat in sight of where I live too).

Effects of global warming are irreversible, report says

---

me@rescam.org

Yes, the effects of global warming will be irreversible for thousands of years. But the amount of future change is still to some extent under our control. A proportion of the probable changes is already built into future climate, but not all of it. The worst-case scenario and even the average-estimate scenario are probably not inevitable if we take prompt action.

The actions required will in my view have to be on individual, national and global levels to have a chance of success.

Also on acid oceans:

There's an interesting article about how climate change has been treated in the press and media in the US and UK. It was published in Feb 2008 by Max Boykoff in Nature and titled The Real Swindle. Max is a research fellow at the Environmental Change Institute at Oxford Uni but doesn't belong to the ClimatePrediction.net research team.

Some good comments and extras all round.

A little something for a general perspective:

Gallery: Putting human consumption into perspective

One comment there about the aircraft contrails... The high altitude warming effect is listed. However, there is also a daytime cooling effect due to reflecting the sunlight back into space. So... Fly only on daytime flights if at all?

That is also just one small example of the balance of effects that must be considered that then allows so much FUD to be pushed by everyone interested. More of a question is which group has a vested interest backed up by loss-and-profits and expensive Marketing?

And then there are those that are in denial and just don't want to know... Too scared of change?

You fly whenever you wish. I know I will. When and how I decide to, just as nearly everyone else does.

Lots of groups have vested interests. Some groups have profit as their motive. Others have forcing their worldview down the throats of others as their motive. Still others don't want to accept that they may be wrong as their motive. Still others may feel (however wrong they may be) that they must save the planet. And on and on and on and on. All of them have vested interests as they perceive them. All of them are capable and willing to push FUD to support their position. No surprise there, they all push their interests.

And then there are those that are in denial and just don't want to know... Too scared of change?

And then there are those that are in denial and just can't understand that perfectly reasonable people disagree vehemently with them... Too scared they might be wrong?

That reminds Me, Some loony guy(no idea who) on Congress.org was saying that contrails were poisoned or something, Of course they aren't, He was just loony.
