Bilbaoya: The earliest measurements of Earth's climate using thermometers and other tools start in the 1850s. Today, the release rate of carbon dioxide (CO2) is roughly 10 times faster than an event some 56 million years ago when earth had extreme warming temperature, as per the study published Monday in the journal Nature Geoscience. Researchers analyzed the biological signatures of deep-sea sediment samples collected off the coast of New Jersey and found the current release of carbon into the atmosphere...

Extreme changes in climate kept large, early dinosaurs from ruling the tropics
2015-06-15 12:00:00| LifeSciencesWorld
[NEWS] Wild swings in climate and lack of consistently abundant vegetation prevented large plant-eating dinosaurs from dominating tropical regions near the equator for up to 30 million years after they first evolved, according to new research. The multi-year, multi-institutional research study published today in Proceedings of the National Academy of Sciences, pieces together a detailed picture of the climate and ecology during the rise of the dinosaurs 230 million years ago….
