The history of atmospheric carbon dioxide on Earth began with the release of the gas from beneath the surface of the newly formed planet. The concentration of pCO2 remained extremely high from Precambrian times to at least the Devonian Period, perpetuated by the release of extremely large amounts...
A massive new review of ancient atmospheric carbon-dioxide levels and corresponding temperatures lays out a daunting picture of where the Earth’s climate may be headed. The study covers geologic records spanning the past 66 million years, putting present-day concentrations into context with ...

and manufacturing accumulate and linger. The problem of plastic pollution on land and in the oceans has only grown as the use of single-useplasticshas burgeoned worldwide. In addition,greenhouse gasemissions, such asmethaneandcarbon dioxide, continue to driveglobal warmingand pose a great threat ...
The rise and fall of atmospheric carbon dioxide therefore coincides with changes in temperature on Earth. During interglacial warm periods, the Earth's average temperature has been about 5 degrees C warmer than during glacial periods. Atmospheric carbon dioxide levels over time in thousands of ...
Charles David Keeling, an American scientist, discovered that the earth was breathing and found that the peak levels of carbon dioxide were rising every year. He recorded carbon dioxide and confirmed the possibility of the gas contributing to greenhouse effect and global warming. Keeling documented ...
Climate change - Abrupt Changes, Earth History, Impacts: An important new area of research, abrupt climate change, has developed since the 1980s. This research has been inspired by the discovery, in the ice core records of Greenland and Antarctica, of ev
There were also reports of quantum teleportation in 1997 and gravitational lensing— a key test of relativity theory — in 1993, as well as the synthesis of carbon nanotubes in 1991, polymer LEDs in 1990 and artificial diamonds in 1993. ...
The alkenone–pCO2 methodology has been used to reconstruct the partial pressure of ancient atmospheric carbon dioxide (pCO2) for the past 45 million years of Earth's history (Middle Eocene to Pleistocene epochs). The present long-term CO2 record is a composite of data from multiple ocean local...
How do human activities affect Earth's climate?Scientists believe that human activity is causing Earth's air to become warmer through the production and release of carbon dioxide, methane, and other greenhouse gases. See all videos for this article ...
