An ocean drill core confirms a dramatic rise in CO2 levels 40 million years ago, just as the Himalayas grew. Even without humans, there are many processes that can change the concentration of carbon dioxide (CO2) in Earth's atmosphere and affect global climate. On page 819 of this issue, Bijl et al. (1) provide the first direct evidence that very high CO2 levels occurred about 40 million years ago during the Middle Eocene Climatic Optimum (MECO), one of the hottest intervals in Earth's climate… 
Eocene oil shales from Jordan - their petrography, carbon and oxygen stable isotopes
Sediment petrographic studies combined with carbon and oxygen stable-isotope analyses are considered to be powerful tools in deciphering the depositional and diagenetic history of carbonate rocks.
Ecology of foraminifera during the middle Eocene climatic optimum in Kutch, India
The shallow marine carbonates of Kutch temporally correspond to the globally recognised warming period called Middle Eocene Climatic Optimum (MECO) that extended from later part of planktic
Climate-Driven Range Extension of Amphistegina (Protista, Foraminiferida): Models of Current and Predicted Future Ranges
The study provides new evidence that amphisteginid foraminifera are rapidly progressing southwestward, closely approaching Port Edward (South Africa) at 31°S and applies a species distribution model (SDM) based on ecological niche constraints of current distribution ranges to project future species distributions.
Synthesis of Knowledge: Fire History and Climate Change
Efforts to quantify relationships between climate and wildfire in Alaska have not yet explored the role of higher-frequency meteorological conditions on individual wildfire ignition and growth. To
Baltic amber impact on historical biogeography and palaeoclimate research: oriental rove beetle Dysanabatium found in the Eocene of Europe (Coleoptera, Staphylinidae, Paederinae)
Baltic amber is a rich source of fossilized organisms and a valuable tool for evolutionary, biogeographical and palaeoenvironmental research. Because it is found in several deposits around the Baltic
A new palaeobatrachid frog from the early Oligocene of Suceag, Romania
It is proposed that the geographical distribution of Albionbatrachus before the ‘Grande Coupure' was wider, extending eastwards into Central Europe, and that the extinction of Albionbatsrachus resulted in the extinction only in the western part of its range.


Transient Middle Eocene Atmospheric CO2 and Temperature Variations
It appears that vast amounts of CO2 were injected into the atmosphere, and a sea surface temperature increase of as much a 6°C accompanied the atmospheric CO2 rise, suggesting that elevated pCO2 played a major role in global warming during the MECO.
Atmospheric carbon dioxide through the Eocene–Oligocene climate transition
The results confirm the central role of declining in the development of the Antarctic ice sheet (in broad agreement with carbon cycle modelling) and help to constrain mechanisms and feedbacks associated with the Earth’s biggest climate switch of the past 65 Myr.

The following report represents a summary of the factors affecting alkenone carbon isotopic compositions, the underlying assumptions and accuracy of short– and long–term CO2 records established from these sedimentary molecules, and their implications for the controls on the evolution of Cenozoic climates.
Coupled Greenhouse Warming and Deep Sea Acidification in the Middle Eocene
[1] The Middle Eocene Climatic Optimum (MECO) is an enigmatic warming event that represents an abrupt reversal in long-term cooling through the Eocene. In order to further assess the timing and
Significant Southern Ocean warming event in the late middle Eocene
A prominent middle Eocene warming event is identified in Southern Ocean deep-sea cores, indicating that long-term cooling through the middle and late Eocene was not monotonic. At sites on Maud Rise
Trends, Rhythms, and Aberrations in Global Climate 65 Ma to Present
This work focuses primarily on the periodic and anomalous components of variability over the early portion of this era, as constrained by the latest generation of deep-sea isotope records.
