Not sure what data you are basing this on. I tend to think we are heading into a cooling period.

They're both basic climate physics, and not related to short-term fluctuations.

  Further, your example was an analogy.
  - DennisP 9y ago
    When you add energy input to a system, it doesn't immediately reach its new equilibrium temperature. That's not an analogy, it's another example of the same physical process.

        Then all of experimental physics is based on analogies.
        philipov 9y ago
        When a comparison between phenomena is made for the purpose of explanation, yes, analogy is commonly used in the teaching of physics. But it is better to say that experimental physics is based on the collection of data about a particular phenomenon, and fitting those data to mathematical models to test how well their predictions hold. And that is not analogy.

        In an experiment you try out a simple system to see how it works. Then you use those same physical principles to figure out how a more complex system works. An example would be heating water on a stove to see how fluids respond to energy input.

  Current temperature is maybe the hottest in recorded history (which is about 150 years) and that is a big maybe. Its definitely not the hottest in human history. Medieval warming period was much warmer than it is now. I would even argue the 1930s were hotter as well.

No, it wasn't. Global aversge temperature is above the peak of anything that might be in the MWP today (the MWP had a really small global effect, with different local warming periods in different regions.) > I would even argue the 1930s were hotter as well. Well, you can argue anything, but finding data to support that argument might be difficult.

      Until about the mid-90s of last century the Medieval Warm Period was for climate researchers an undisputed fact. The IPCC itself reported this as such in their 1990 report and included this graph. https://i1.wp.com/www.science-skeptical.de/wp-content/uploads/2009/11/lambh23.jpg?zoom=2 https://i1.wp.com/www.science-skeptical.de/wp-content/upload... Here is another chart published by IPCC in 1995 it shows both the Medieval warm period and the 1930s as being hotter than it is now. https://stevengoddard.files.wordpress.com/2011/05/screenhunter_78-may-11-10-03.gif https://stevengoddard.files.wordpress.com/2011/05/screenhunt... Since then there has been an effort to erase this data from the record because it contradicts current climate change narrative. None of what Im saying is a theory. These are facts and there are loads of leaked emails and testimony under oath that says as much. https://www.youtube.com/watch?v=u1rj00BoItw https://www.youtube.com/watch?v=u1rj00BoItw Up your research game my friend.
