  • The finding that the shells of certain algae can contain a signature of low levels of atmospheric carbon dioxide has prompted the discovery of the emergence of this signature in the fossil record. Here, experts discuss the implications of this for climate science and ocean ecology. See Letter p.558

  • The need to mitigate climate change opens up a key role for cities. Bristol's year as a Green Capital led to great strides forward, but it also revealed that a creative and determined partnership across cultural divides will be necessary.

  • It has been suggested that high-latitude methane emissions from terrestrial environments could have enhanced a period of global warming about 55 million years ago. A decrease in the carbon isotope values of hopanoids (a biomarker derived from bacteria) at the onset of the warm period is reported, which suggests an increase in methanotroph populations . This could reflect an increase in methane production and release from the terrestrial biosphere, which could have acted as a positive feedback mechanism in global warming.

  • The Early Cretaceous greenhouse interval may have been punctuated by cooler periods. A reconstruction of sea-surface temperatures from low and middle latitudes shows no evidence of such cold events.

  • The relationship between atmospheric CO2 and climate during the Eocene greenhouse remains uncertain. Here authors show that Eocene CO2 and climate sensitivity was high during the warmest intervals and declined as global climate cooled, with implications for the Earth’s future warming climate.

  • The effect of Asian summer monsoon hydrological changes on key biogeochemical processes remains poorly understood. Here, using a suite of biomarkers, the authors reconstruct palaeohydrological conditions during the Holocene and show that the peatland carbon cycle is strongly sensitive to paleohydrological changes.

  • A new record of Pliocene carbon dioxide variations derived from boron isotopes shows that climate sensitivity (the change in global mean temperature in response to radiative forcing) during the Plio-Pleistocene does not vary when cycles in continental ice are taken into account; this suggests that current estimates can be used to predict future climate.

  • Deforestation and edge effects around cleared areas impact forest stability. Here, the authors examine human impacts on Amazonian forest-savanna bistability and show that tree cover bimodality is enhanced in regions close to human activities and is nearly absent in regions unaffected by human activities.

  • Reconstructions of Earth's past are much more than benchmarks for climate models. They also help us comprehend risk by providing concrete narratives for diverse climates.

  • A period of ocean anoxia about 120 million years ago coincided with high temperatures. A reconstruction of CO2 concentrations shows that volcanic outgassing from the Ontong Java Plateau caused CO2 levels to double during the anoxic event.
