Equatorial convergence of India and early Cenozoic climate trends.
India's northward flight and collision with Asia was a major driver of global tectonics in the Cenozoic and, we argue, of atmospheric CO(2) concentration (pCO(2)) and thus global climate. Subduction of Tethyan oceanic crust with a carpet of carbonate-rich pelagic sediments deposited during transit beneath the high-productivity equatorial belt resulted in a component flux of CO(2) delivery to th...
متن کاملInsect herbivory, plant defense, and early Cenozoic climate change.
Insect damage on fossil leaves from the Central Rocky Mountains, United States, documents the response of herbivores to changing regional climates and vegetation during the late Paleocene (humid, warm temperate to subtropical, predominantly deciduous), early Eocene (humid subtropical, mixed deciduous and evergreen), and middle Eocene (seasonally dry, subtropical, mixed deciduous and thick-leave...
متن کاملPacific Ocean and Cenozoic Evolution of Climate
[1] The Pacific Ocean has played a major role in climate evolution throughout the Cenozoic (65–0 Ma). It is a fundamental component of global heat transport and circulation, the dominant locus of primary productivity, and, consequently, the largest reservoir for carbon exchange between the oceans and the atmosphere. A satisfactory understanding of the Cenozoic evolutionary history of the Pacifi...
متن کاملCenozoic Climate ^ Oxygen Isotope Evidence
Discoveries of fossil remains of 50 million year old alligators on Ellesmere Island and 30}40 million year-old forests on Antarctica contrast sharply with our present vision of polar climates. These are not isolated discoveries or quirks of nature. An evergrowing body of faunal, Soral, and geochemical evidence shows that the Rrst half of the Cenozoic Era was much warmer than the present time. W...
متن کاملAn abyssal carbonate compensation depth overshoot in the aftermath of the Palaeocene–Eocene Thermal Maximum
1 The PETM represents one of the largest and most abrupt greenhouse warming events in Earth’s history. Marine and terrestrial records document a global >2.5‰ negative carbon isotope excursion (CIE; refs 1–3) coincident with global mean surface ocean warming of >4 °C (ref. 4) and geochemical and sedimentological evidence for ocean acidification5,6. Collectively, these lines of evidence suggest a...
