- Climate monitoring stations around the Arctic have measured carbon dioxide levels of 400 parts per million in the latest set of atmospheric data. The global average is 395 parts per million. Both figures are well in excess of the highest non-catastrophic level of carbon dioxide, 350 parts per million. Since the Arctic is a leading indicator, global levels will probably hit 400 parts per million soon.
- A portion of rainforest in Guatemala that is hotspot for reptile and amphibian diversity was preserved as the Sierra Caral Amphibian Reserve. The reserve also has populations of Highland Guan, Great Curassow, and Keel-billed Motmot.

- Hawkmoths are able to sense humidity well enough to determine whether a flower has enough nectar to be worth a visit.
