Climate Campaigners Say ‘Listen to the Science’ as New Study Shows Earth Now Warmer Than Any Time in Last 12,000 Years
The study “changes the baseline and emphasizes just how critical it is to take our situation seriously,” its lead researcher said.

Climate campaigners on Thursday pointed to a study showing that Earth is hotter than it’s ever been during the entire epoch of human civilization as the latest proof of the need to treat human-caused global heating like the dire emergency that it is.
“The modern, human-caused global warming period is accelerating a long-term increase in global temperatures, making today completely uncharted territory.”

On Wednesday, the peer-reviewed scientific journal Nature published a report revealing that an analysis of ocean surface temperatures found that the planet is hotter now than at any other time in the past 12,000 years, and that it may actually be warmer than at any point during the last 125,000 years.
Researchers Samantha Bova, Yair Rosenthal, Zhengyu Liu, Shital P. Godad, and Mi Yan detemined this by solving what scientists call the “Holocene temperature conundrum.” This was the mystery of why the global heating that began at the end of the last ice age 12,000 years ago peaked around 6,000 years later—before giving way to the onset of a cooling period that lasted until the Industrial Revolution, when the current anthropogenic warming period began.
It turns out that the collected data, obtained from fossilized seashells, was innacurate, showing only hot summers while missing the colder winters.
