People started keeping relatively widespread careful measurements at the end of a little ice age ... what do these liar expect but warming?
“People started keeping relatively widespread careful measurements at the end of a little ice age .”
Little Ice Age is usually defined as ending about 1850, some say earlier. In 1850 accurate standardized weather measurements were being conducted mostly in Europe, East Coast of North America, some on the West Coast. A handful of other places would have existed in North and South Africa, Australia, New Zealand, some parts of Asia and a few other spots, but no global coverage by any definition. Not until WW2 was there anything close to global coverage. Really global coverage started in the 1960-70’s with space based measurements. At best we have less than 100 years of good records.
