@okie,
The problem okie is you rely on one small thing you think undermines the overwhelming science while ignoring the mountain of things that support it.
If the temperature stations are off then why do satellite readings show warming?
If the temperature stations are off then why does recorded ice out occur earlier?
If the temperature stations are off then why do migratory birds stay north longer?
If the temperature stations are off then why are warm weather species moving farther north?
It the temperature stations are off then why is the growing season longer?
If the temperature stations are off then why is the fire season worse in the western US? (earlier snow melt leads to drier summers)
If the temperature stations are off then...... the list goes on and on okie.
But in reality okie.. If the warming is found by finding the change in readings and not in the readings themselves then why would the error be in one direction for all those weather stations?
