'Wind power causes climate change' shown to be so much hot air

Re: Consistent

It might help if you converted the percentage of power in to the percentage of a hurricane.

For example x% of a hurricane or y% of the jet stream.

Then people might realise the climatic change it is going to have.

We aleady use 7 hurricens of wind a year!!!

(well we would if they wind farms ran at capacity, which they don't but we probably use a hurricane or two, that is bound to affect climate, it's a no brainer!!)

Wind is the earth's convection cooling system, every gigawatt of power you get from the wind is a gigawatt of cooling power removed from it.

That is of course if the system is 100% efficient which it will not be, you are probably going to remove 2 units of cooling power for every unit of power you generate.

But leave that aside a moment and consider this, the currently installed wind farms over a year running at capacity will from 7 Hurricanes of wind from the the atmosphere. That is 7 hurricanes of cooling power!! We only get 9 hurricanes a year to put that into perspective.

So no surprise the jet stream has gone loopy in my opinion, and of course meddling with a cooling system is a stupid thing to do, especially one driven by convection, a fragile process, a change in one place will have knock on effects affecting the whole system.

I would also draw attention to some statements which surprise me:-

"A significant increase in temperatures was observed, especially at night, near these farms. It turns out that at night, wind turbines mix the atmosphere more than they do during the day, which reduces cooling near the ground."

I don't have much confidence with the approach they are using, it seem to me they are starting in the one place. If the turbines reduce the wind-speed from X to Y of a volume of air A them that volume of air is prevented from rising. So A(x-y) cubic metres of warm air has been prevented form rising, that has got to produce a warming effect!! Air can't rise unless air move in beneath it!!

This 'mixing' idea is a bit of a red herring I fear, it's not the "big issue", however even them a "significant increase in temperatures was observed", it does not matter if it was mainly at night, they don't switch them off at night do they!!!

Also you can't dismiss it as 'mixing' that warm air still has to rise again and wind is required to allow it to rise, otherwise it is stuck.

Also this:-

"The main conclusion is that differences caused by wind turbines remain very small compared to natural climate variability: in some regions, the difference in temperature reaches 0.3°C at the most"

0.3C? Small? Well the warming over the last 100 years has been only about 0.8C so we can ignore that as well!! And this figure was from a simulation apparently.I really have no faith in them being able to produce an accurate simulation, garbage in, garbage out.

Also there is nothing local about heat or wind, you might only notice it locally but affects the weather thousand of miles away if only slightly.

Meddling with the wind is bad, slowing down climatic system can have devastating effects, causing flooding and droughts in general any persistent weather pattern is bad news and we seem to have that at the moment. It is worse than warming in it's destructive power in my opinion much worse.

And we are steam rolling ahead into the unknown blindly.

Were in charge I would chop all wind turbines down until we know what we are doing.

As I said earlier, you can't expect to take a few hurricanes of wind out of the weather system and not notice.

I read this " "between 72 and 170 TW could be extracted in a practical and cost-competitive manner".[30] They later estimated 80 TW.[31] However research at Harvard University estimates 1 Watt/m2 on average and 2–10 MW/km2 capacity for large scale wind farms, suggesting that these estimates of total global wind resources are too high by a factor of about 4."

Well we currently extract 0.3TW, so if we plan to extract say a conservative 30TW, may I remind you that that is 700 HURRICANES over the year!!!

WE WILL ALL DIE IF THEY DO!!

We will suffocate in stagnate air, assumed we have not all starved from crop failure first!!!
