What is the real story around heat pumps?

You are aware that you are in disagreement with about everyone who does research in that area professionally, right?
--- Quote from: nctnico on February 24, 2024, 12:59:57 am ---There is only chaos in the weather system.

You are aware that "the weather system" is to climate as "resistor noise" is to an amplifier, right? Do you also think that amplifiers don't produce any useful signal because the resistor noise in the bias resistors is only chaos?
--- Quote from: nctnico on February 24, 2024, 12:59:57 am ---You can't even be 100% sure that the temperature change we're seeing is due to human activity.

Are you saying that you can only be 99% sure, or are you saying that you can only be 1% sure?
If the former: How is this a relevant objection, then?
If the latter: You are aware that you are in disagreement with about everyone who does research in that area professionally, right?
--- Quote from: nctnico on February 24, 2024, 12:59:57 am ---There are so many factors that you can't even begin to create a suitable model. For starters take the huge amount of energy the sun is supplying to the earth. Even a small fluctuation can have a massive effect and this happens as the sun's energy output isn't constant at all. Data shows that sun has been outputting more energy since 1700. But you can't even start to claim that causes an increase in temperature. It might as well cause a decrease in the long term.

You are aware that you are in disagreement with about everyone who does research in that area professionally, who also happen to be aware of the sun's behaviour, right?
--- Quote from: nctnico on February 24, 2024, 12:59:57 am ---Nowadays the news is way to quick to attribute every bit of rain (or lack thereof) to climate change.
--- End quote ---
... so? Do you think that because some news journalist says some nonsense, that therefore, there is noone on the planet who actually has a clue on the respective topic? Like, how is this relevant here?
--- Quote from: nctnico on February 24, 2024, 12:59:57 am ---Accurate data goes back only 100 years or so.
--- End quote ---
You are aware that scientists who work on climate change have many natural data sources that go back way longer than human weather records, right?
In particular, you did notice that you seem to be convinced that there was significant glaciation about 20000 years ago, even though that is in fact longer than 100 years ago?

Is this what this forum has become? 5% useful posts on actual heatpump data, 95% argument?

Welcome to the internet.

Something about heatpumps brings out the crazies, not just this forum. So the OP asking for honest answers (being overwhelmed by the noise) is fully understandable.

Total bullshit. You only have to visit these countries to see. Africa pretty much the same. The reason they are used for heating is not only environmental, or good COP. It's convenience. One single unit does both, so you don't need separate systems for heating and cooling. In climates where heating needs are modest, having a separate system when your "cooling" unit can do the same is just insane. Similarly, wrapping in blankets in cold moist winter days without heating is just insane when you can have heating from the same heatpump by paying $50 more for the unit. And electricity in these countries is cheaper than it is for you in the UK. Even if you are very poor and saving in heating or cooling cost by heating/cooling less, you would still have the system.
