New global warming study warns of rising temperatures using data from 19th century, when the Earth was warmer
A new climate change study warns “Global warming could be far worse than predicted, new study suggests” and “Global Warming Is Worse Than We Thought And Could End Up Double What We Predicted [Study].”
What drive the “shocking” new information: evidence from three warm periods that occurred when Earth was 32.9 degrees F (0.5 degrees Celsius) to 35.6 degrees F (2 degrees C) hotter than pre-industrial 19th-century temperatures.

Yes, you read that right: when the Earth was warmer during the pre-industrial 19th-century (0.5 -2 degrees Celsius) warmer!
“This suggests the carbon budget to avoid 2°C of global warming may be far smaller than estimated, leaving very little margin for error to meet the Paris targets,” said Hubertus Fischer, lead author and University of Bern professor, of the new model.
Tech Times summarized this: The researchers derived their conclusion from their analysis of three warm periods, namely the Holocene thermal maximum period some 5,000 to 9,000 years earlier, the last interglacial period 129,000 to 116,000 years ago, and the mid-Pliocene period some 3.3 to 3 million years earlier.
The warming of the first two periods was caused by predictable changes in the Earth’s orbit, while the mid-Pliocene event was the result of atmospheric carbon dioxide concentrations that were 350-450ppm — much the same as today.
Research data was compiled from “ice cores and fossil records” as the experts warn “Sea-level rise could persist for thousands of years, warned Alan Mix, co-author and Oregon State professor.”
Mix explained that current models may be relied upon for low-emission scenarios in the decades leading up to 2100, but not really for larger or higher-emission scenarios.
“We can expect that sea-level rise could become unstoppable for millennia, impacting much of the world’s population, infrastructure and economic activity,” Mix said.
Uh-huh.
We know this by studying how the Earth was WARMER before we had an INDUSTRIAL REVOLUTION.
So, cutting down on emissions would help or stop the problem?
Well, Science Daily couldn’t help themselves with their hysteria: “The research also revealed how large areas of the polar ice caps could collapse and significant changes to ecosystems could see the Sahara Desert become green and the edges of tropical forests turn into fire dominated savanna.”
We MUST URGENTLY address emissions or else…
The findings are discussed in the journal Nature Geoscience.
