I suspect that rather than try to heat things up they are trying to block the suns light in an attempt to cool things down.
The weather is OFF all over the planet. Check the news.
If you own a globe, check unusual weather and make notes on location.
Then tip the N axis point 10-15 degrees towards the UK and see the the winter and spring temps are off.
I have done this and they are off.
Antarctica is 2.5 deg C warmer than the ocean that surronds it. (it shouldn't be, if anything, it would be colder due to the reflection of the sunlight off the ice.)
There are lots of scientific sutdies that separately add up to nothing.
Put them together and you will get a very clear picture.
Also, if the suns position is indeed off, it becomes very difficult to track the position of the sun when you can't see it.
