I didn't say that it was inaccurate i said that taking 200 year trend when climate patterns can last thousands of years
is not reliable.
you also have to realize that the years they are using was at the end of the little ice age. so they are starting from the bottom trough
and looking up. that is called data bias.
Medieval Warm Period - an overview | ScienceDirect Topics
right now temps are pushing about the same as they were during the Medieval warming period
and just slightly higher than the warming period during the romans.
there was a warming period before that which was even higher than it is now.
all it takes is a bit of research to see that we are in what is nothing more than a normal warming phase.
how long it lasts who knows. we don't know what triggers earths warming and cooling phases although we have a good idea.
a lot of it has to do with the solar system and with the ocean currents.
along with troposphere activity and other events going on.
