1850 has typically been used due to that being the end of the Little Ice Ace, and, per the cult, when Mankind started clogging up the atmosphere with “carbon pollution”. So, what is the point of this?
New data raises questions about how much the Earth has warmed
Planet-warming pollution rates exploded after the end of World War II. James Watt’s steam engine launched the Industrial Revolution in 1769. Before that, for thousands of years, humans were clearing forested land for farming, releasing carbon from trees and plants into the atmosphere.
The severity of global warming has long depended on your frame of reference — on what temperature you think was normal for the Earth before humans began changing it. But what year should mark that moment?
That’s what makes a groundbreaking new temperature dataset released by a group of scientists based in the United Kingdom so striking. The datasets used to diagnose the modern history of the planet’s climate — and to proclaim that the world is now very near to 1.5 degrees Celsius (2.7 degrees Fahrenheit) of warming — typically begin with the year 1850.
The new one goes all the way back to 1781.
This extended time frame matters because greenhouse gases in the atmosphere increased 2.5 percent between 1750 and 1850, enough to have caused some warming that the data hasn’t accounted for.
I assume the point is to say that Mankind ended the Little Ice Age, not natural causation.
The new temperature record, dubbed GloSAT, helps contribute to the growing sense among scientists that the Earth has warmed more than what calculations based on the 1850 starting year would suggest.
See? It’s all your ancestor’s fault. Anyhow, would you be super surprised if they used climate models to create data temperature from the 1700s which, for the most part, didn’t exist. It’s just a continuation of the scam.
The temps are now rising much
faster than they were 175 years ago. Teach seems not to acknowledge that preferring yo repeat the miniscule fabrication.
The little ice was a a regional climactic event not global. A graph showing global temps over the last 2000 years will in fact show unprevented “skyrocketing” global temps with only one possible explanation. The same one that Reagan earned us about in the 80s.
Aw c’mon, 97% of scientists agree that the satellite temperature records from 175 years need to be recalibrated to 21st century standards.
Geez…
