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.
A.S.S.
“The little ice was a a regional climactic event not global.”
No. The Chinese released studies that showed it in Asia and other parts of the world.
BTW – Explain please why climate change would exist only in parts of the world?
I am waiting.
Are you really asking why or how some areas have different climates than others? Why is Antarctica colder than Syria??
The increase in the global mean (average) surface temperature is the global mean (duh!). This is not to imply that the Arctic, the Amazon basin, southern Greenland, the South Pacific have all had an identical 1.4 °C (2.5 °F) increase.
For example, the Arctic appears to be warming fastest – at three to four times the global average, driven by melting ice and albedo effect feedback loops; Europe is the fastest-warming continent, warming twice as fast as the global average, due to Arctic influences and other factors.
There is no conspiracy; no plot; no ulterior motive. That doesn’t mean the scientific community is correct, although that is more and more likely. That’s how science works!!
“Temps are rising faster than 175 years ago..”. Which is irrelevant unless one can prove there’s a “climate crisis” as the effect of that }. But one can’t
True. One can only speculate about what the effects of rapid warming will be – educated guesses, if you will.
Aw c’mon, 97% of scientists agree that the satellite temperature records from 175 years need to be recalibrated to 21st century standards.
Geez…
The right-wing has lost the scientific argument, bigly, overwhelmingly.
But, you MAGAts have won the war!
Little Donnie won the election, so his scientific illiteracy rules!! Have fun!!
How so? What scientific argument? This should be good….
That the accumulation in human-generated CO2 is causing the mean global surface temperature to increase. Duh.
You have been dragged kicking and screaming to that conclusion, but even you know it’s true!
First the cultists denied it was warming. Then they denied CO2 was the cause. Now they claim there are no effects. Next they will say there is just nothing that can be done – that we’ll adapt!
Relax. You’ve lost the scientific Battle, but won the War!!! Bigly!!!
Relax, William. Your Cult of Dumbness is safe as long as Little Donnie is the Boss!! This was a single study – scientific consensus rarely depends on one study.
Keep on denyin’!
Our esteemed host asked the right question:
The point is to produce a paper to justify their jobs being continued.
“Conspiracy” is the cornerstone of conservatism. Nefarious actors are conducting their nefarious actions to further their own nefarious causes!
Fortunately, science doesn’t work that way.
According to conservatism and MAGAtism, “Science” is a conspiracy created by Atheists to defeat christianity – the “science cult” “created or invented” Evolution, the Big Bang, Global Warming, the Solar System, atoms, age of the Earth, psychology, gender, archaeology, dinosaurs etc all in an attempt to invalidate the Bible, The True Word of G0d!!
Conservatives consider man-made global warming to be just another religious-like belief akin to their own beliefs in gods, demons, nirvana, hell, life after death, miracles, reincarnation, 72 virgins for martyrs, revelation…
