A new study from University of Michigan climate researchers concludes that some of the latest-generation climate models may be overly sensitive to carbon dioxide increases and therefore project future warming that is unrealistically high.

Fishery collapses can be difficult to forecast and prevent due to hyperstability, a phenomenon where catch rates remain high even as fish abundance declines. In a recent Canadian Journal of Fisheries and Aquatic Sciences study, researchers conducted a whole-lake experiment to reveal the causes of hyperstability in recreational fisheries. Fish habitat preferences were found to leave them vulnerable to overexploitation.

THE Oxford Dictionary describes the environment as "the surroundings or conditions in which a person, animal, or plant lives or operates". Humankind has been reliant on the environment for its existence for as long as humans have been living on earth. In numerous ways, the future survival of humankind will depend on how we take care of our air, soil, rivers, oceans, animals and plants.

When did you last see a glow worm? Most likely, quite some time ago. Depending on how young you are, you may have never seen one at all. Those light-emitting insects, Wordsworth's "earthborn stars", have been declining in the UK for decades. That means that scientists now see them in fewer places, and even in those pockets where conditions are right for them, there are fewer of them to be found.

To imagine earth without greenhouse gases in its atmosphere is to turn the familiar blue marble into a barren lump of rock and ice on which the average surface temperature hovers around -18ºC. Such a planet would not receive less of the sunlight which is the ultimate source of all Earth's warmth. But when the energy it absorbed from the sunlight was re-emitted as infrared radiation, as the laws of physics require, it would head unimpeded back out into space.

And against the backdrop of threatened lives, crippled businesses and damaged economies, the UN chief warned the Petersberg Climate Dialogue in Berlin that the Sustainable Development Goals (SDGs) are also under threat.

"Pollinators were the key," says Edgar Mora, reflecting on the decision to recognise every bee, bat, hummingbird and butterfly as a citizen of Curridabat during his 12-year spell as mayor.

The surprise player in affecting workplace safety overseas? Multinational buyers.

The world's two largest economies are both partners and rivals, deeply intertwined but also with divergent interests. How will these contradictions resolve themselves following COVID-19?
