Methinks you are using 20th century data.

To quote NASA: "globally averaged temperatures in 2017 were 1.62 degrees Fahrenheit (0.90 degrees Celsius) warmer than the 1951 to 1980 mean, according to scientists at NASA’s Goddard Institute for Space Studies"

As you may know, this baseline temperature is well above that of 1880 (about 0.5 degrees, perhaps)

Using an average as a baseline is a good idea, as it significantly reduces the effect of short term oscillations such as El Nino.

An appropriately smoothed temperature is about 1 degree Celsius above the value for 1880 at present.

It is a fool's errand to believe windmills were ever a  good idea near salt water.  Salt is unbelievably corrosive to iron or steel.  More dead windmills than working units.

Uhm we're building them in the middle of the sea. Works fine. But yeah its salt water obviously, so they should be protected.

It's like metal ships. It is beyond the capability of engineers to build them so that they can be used at sea.  Oops. Just realised that isn't such a good argument.

 

Firstly, wind turbines are generally considered to have a modest lifetime of about 25 years, after which they can be mostly recycled. Secondly, technology has advanced very considerably since the ancient times of the 1980s. Engineers know way, way more than you, but are far less arrogant about it, and will do a great job, I am confident.

 

The point about the threat to birdlife is important and needs to be addressed. I am surprised there has not yet been a breakthrough in developing technology to keep birds and bats away from wind turbines: surely there is some way to do this. However, I have learnt that the number of deaths is small compared to those from (1) birds flying into buildings and (2) birds being caught by domestic cats. In very few cases is it large enough to be a significant threat to ecosystems. Perhaps more pertinent is that other forms of power generation such as nuclear can kill more birds.

We have many fully operational wind farms in my part of the country (one, 8 miles away, I have photographed from my bedroom window). Yesterday, one of the hubs caught on fire and someone posted a photo of it blazing furiously! Many millions of pounds, but I am sure they have allowed for such occasional failures. 15% of UK electricity comes from wind now, growing rapidly.

And so we have today`s instalment of ELROCK useless information.

Could this be because no one was there for ELROCH as a child and now in an attempt to get noticed (which is a substitute for love) he/she believes this is the avenue to seek this notice?

What????

He was providing information on the subject of this thread.

That (rather unusual and spectacular) wind turbine fire got into the news. I cycle past that wind farm often. Apparently only a million pounds: they have got a lot cheaper. To put this in proportion, 1 in 20,000 wind turbines catches fire each year which is about 1/50 the rate for dwellings.

  • Wind energy: the cheapest source of electricity in the UK from the latest onshore developments. 15% of UK electricity in 2017 for this little overpopulated island you and I inhabit, and growing rapidly. 
  • Solar energy: the very cheapest electricity in hot climates. About half as good even in the UK (which makes it a useful component to the mix - currently over 3% of generated electricity).

I understand 87. You cannot provide an answer because it forces you to think about the future and that is not something you can do because your argument is flawed. Why don't you ask the people who have been flooded out of their homes in many parts of the world. Or the people who have seen their properties destroyed by hurricanes or wildfires. Or the people that have had to abandon their lands because of drought. Ask them if they feel fortunate to be living in a warming trend. 

And bear in mind that this is after 1 degree of warming. What will happen after 2, 3 or 4 degrees of warming? 

All the experts warn that the consequences will be dire. But you, 87, don't believe them because you are a conspiracy theorist just like the rest. You are as deluded as a flat-earther or someone who insists man never set foot on the moon. In fact worse than them because their screwy theories are not really doing anybody any harm. Yours are and will cause harm to future generations.

It would be a shame to wreck the progress of a very vulnerable country.

So what are you trying to say with all this endless information?

GLOBAL WARMING- IT`S REAL DUMMIES...now tell us something that we don`t know!!!

Let me introduce you to this technique for increasing knowledge called reading.

There’s trillions of metric tons of natural gas in Alaska. Just saying. Seems like the future of energy.....And yes it is still my unscientific opinion that man made global warming isent the big bad wolf it’s made out to be. It’s all part of a perfectly natural cycle since forever mainly driven by the sun and volcanic activity. Trees and plants give us oxygen and would die without carbon which billions of us breathe into the atmosphere on a second to second basis. We have bigger fish to fry than man made global warming

This whole idea of man made global warming came from politically motivated profiteers backed by pseudo science with the end game of a global multi trillion dollar carbon tax which Denmark has been paying into since the 1940s

The scientific method is designed to be RIGHT far, far more often that a random opinion guided by subjective preferences.  That is why there is no genuine debate here: you are wrong and you have the choice of remaining wrong or accepting the facts.

Meanwhile, essentially every country on the planet signed to agree not only with the facts but with the need to mitigate the problem two years ago.

ARE YOU TOO SLOW TO GET THAT BIG A HINT?

Correction - you have it all wrong from start to finish.
