Latest Carbon dioxide in the Earth's atmosphere Stories
The cactus, stalwart of the desert, has quite a story to tell about the evolution of plant communities found the world over.
The Earth may be able to recover from rising carbon dioxide emissions faster than previously thought, according to evidence from a prehistoric event analyzed by a Purdue University-led team.
University of Alberta researchers have determined that the influence of northern peatlands on the prehistorical record of climate change has been over estimated, but the vast northern wetlands must still be watched closely as the planet grapples with its current global warming trend.
A research project completes drilling for the year, reaching two miles below West Antarctic Ice Sheet.
Genghis Khan and his Mongol hordes had an impact on the global carbon cycle as big as today's annual demand for gasoline.
The magnitude of climate change during Earthâ€™s deep past suggests that future temperatures may eventually rise far more than projected if society continues its pace of emitting greenhouse gases, a new analysis concludes.
According to a popular hypothesis, grasses such as maize, sugar cane, millet and sorghum got their evolutionary start as a result of a steep drop in atmospheric carbon dioxide levels during the Oligocene epoch, more than 23 million years ago.
A new analysis of fossilized grass-pollen grains deposited on ancient European lake and sea bottoms 16-35 million years ago reveals that C4 grasses evolved earlier than previously thought.
New University of Florida research puts to rest the mystery of where old carbon was stored during the last glacial period.
Water vapor and clouds are the major contributors to Earth's greenhouse effect, but a new atmosphere-ocean climate modeling study shows that the planet's temperature ultimately depends on the atmospheric level of carbon dioxide.
