The y-axis on the graphic in the News story ‘US–China climate deal raises hopes for Lima talks’ (Nature 515, 473–474; 2014) was out by a factor of 10. It should have been 0–35 gigatonnes not 0–3.5 Gt.

The picture caption in the story ‘Ocean observatory project hits rough water’ (Nature 515, 474–475; 2014) gave the wrong date for the completion of the Ocean Observatories Initiative network: it will finish in May 2015, not March.

The story ‘Green List promotes conservation hotspots’ (Nature 515, 322; 2014) misstated why original inhabitants of the Chagos Islands cannot return: it is owing to policies of the British Indian Ocean Territory administration.

The article ‘Rival species recast significance of ‘first bird’’ (Nature 516,18–19; 2014) incorrectly referred to ‘Microraptor xui’ instead of ‘Microraptor gui’. It also failed to attribute the Archaeopteryx silhouette in the graphic to Vladimir Nikolov.

The story ‘Climate tinkerers thrash out a plan’ (Nature 516, 20–21; 2014) incorrectly stated that discussions at the meeting would feed into a report that the US National Academies intends to release early next year. And the caption stated that the futuristic device would spray sea water into the stratosphere. Actually, the lower atmosphere is the target.
