Although sun radiation was relatively low, the temperature on the young Earth was warm. An international team of geoscientists has found important clues
High CO2 Levels in the Air were Responsible for High Temperatures on Young Earth

The temperature on the young Earth was warm despite that radiation of the sun was comparatively low. An international group of geoscientists has discovered essential clues that high levels of carbon dioxide (CO
2) in the air led to such high temperatures.

2 was slowly captured and stored on the newly forming continents.
Three to four billion years ago, very high atmospheric CO
2 levels caused the high temperatures on the still-young Earth. During that time, the Sun shone with only 70%–80% of its current intensity. However, the climate on the young Earth was quite warm since there was barely any glacial ice.
Although sun radiation was relatively low, the temperature on the young Earth was warm. An international team of geoscientists has found important clues that high levels of carbon dioxide in the atmosphere were responsible for these high temperatures. It only got cooler with the beginning of plate tectonics, as the CO2 was gradually captured and stored on the emerging continents.
Scientists win funding for Azores deep sea expedition
A team led by the Okeanos Research Center at the University of the Azores has secured funding for the Eurofleets + project to carry out a scientific expedition to areas of the deep sea never visited before . The funding now guaranteed by the Deep Sea Research Group of the Okeanos (research center) of the University of the Azores will allow a scientific expedition to explore unknown areas of the Mid-Atlantic Dorsal, over a period of 17 days , says researcher Telmo Mourato, who will lead the mission.
The Mid-Atlantic Dorsal is a volcanic mountain range that extends from the Arctic to Antarctica, being the dominant topographic structure of the Atlantic Ocean and the most extensive mountain range in the world. The expedition will map the bottoms of this region and characterise the coral communities and sponges that inhabit the ridges and seamounts in Dorsal. It also intends to identify the environmental factors that determine t
