Their findings, published in
Nature, show that the annual global temperature today is the warmest of the past 10,000 years contrary to recent research.
Some skeptics contend that climate model predictions of future warming must be wrong. The scientists, however, say their findings will challenge long-held views on the temperature history in the Holocene era, which began about 12,000 years ago.
“Our reconstruction shows that the first half of the Holocene was colder than in industrial times due to the cooling effects of remnant ice sheets from the previous glacial period contrary to previous reconstructions of global temperatures,” says lead author Samantha Bova, a postdoctoral researcher associate in the lab of coauthor Yair Rosenthal, professor in the department of marine and coastal sciences and department of earth and planetary sciences at Rutgers University-New Brunswick.

The Long-Standing Mystery of Climate Change Resolved
Written by AZoCleantechJan 28 2021
According to a study under the guidance of Rutgers University, the main mystery behind climate change has been resolved by the researchers, which shows that the current yearly global temperature is the warmest of the last 10,000 years in contrast to recent research.

The study has been published in the journal
Nature.
The long-term mystery is known as the “Holocene temperature conundrum,” with few skeptics claiming that climate model forecasts of future warming must be incorrect. The researchers add that their results will contradict the long-held opinions on the temperature history in the Holocene era, which started around 12,000 years ago.

Scientists claim to have found the âmissing linkâ in the process that leads to an ice age on Earth.
Melting icebergs in the Antarctic are the key, say the team from Cardiff University, triggering a series of chain reactions that plunges Earth into a prolonged period of cold temperatures.
The findings have been published today in Nature from an international consortium of scientists from universities around the world.
It has long been known that ice age cycles are paced by periodic changes to Earthâs orbit of the sun, which subsequently changes the amount of solar radiation that reaches the Earthâs surface.
