RE: Rising the Earth's temperature... with dark matter
Woa! This is a thought provoking post @lemouth :)
The question I have might not even be relevant to the study itself. But, I am going to ask away anyway: If dark matter annihilation indeed contributes to the rise of Earth's temperature, in what ways men could interfere with this in order to slow down global warming?
The illustration is awesome ! :D
The post is actually not provocative at all. It is state-of-the-art science. But to say the truth, I agree the title of the post and the first image are provocative (and funny too, aren't they?) :)
One must be careful on what is the cause what is the consequence here.
First of all, there is a heat flow outgoing from the planet. It is well measured: 47 TW (with an uncertainty of about 5% on the number). This measured quantity is included in the climate models that deal, among others, with the global temperature no the planet. Therefore, dark matter can or can't contribute to the 47 TW. This will always be 47 TW (it is measured).
Next, let's take a dark matter model. Sometimes, there is a contribution to the heat flow of the planet (the 47 TW), sometimes not. When such a contribution exists, it must be calculated and one must verify that it does not challenge the 47 TW measurement. If it is the case, the model is just excluded.
Therefore, this model has no influence on climate changes at all. It can contribute to one parameter of the climate models, that is taken as a measured value anyways.
Is this clearer?
I see, I see ... Thank you @lemouth, for taking the time to make this clear. Despite not having fully grasped it, I found this post particularly interesting. But, now I feel I have a better understanding of it, which made it all the more fascinating.
Yes! The illustration is incredibly witty :D I love it!
Wish you and the family a great weekend ahead! <3
Thanks for the wishes, although it is already Tuesday (I spent the week-end to travel to China). I hope you had a nice week-end too, and please do not hesitate to come back to me if needed :)
