Scientists say the giant manta ray, known as a gentle leviathan, is in fact a "predator of the deep" preying on fish and other animals. Image: BBC - Giant manta rays can be identified by their spots and blotches The ray, which can grow up to 7m (23ft) across, was thought to feed on tiny floating animals at the surface. New evidence shows much of the ray's diet is made up of food from the deep. The finding raises questions about the future of the giant manta ray, which is listed as a vulnerable species.   According to the International...

Activism, ClimateChange, Environment, Habitat, Indigenous Peoples, Protest, Science, Study -

Preventing deforestation is central to curbing carbon emissions – and a case study on the Amazon shows the most cost-effective way of doing it. Explorer, author, award-winning documentary maker and advocate for indigenous people’s rights, Bruce Parry, has written this thought provoking peice: I’ve spent a lot of time with indigenous peoples in remote places. So when I argue that the best way – or at least the cheapest way – to stop climate change is to grant land rights to indigenous communities, you might suspect I’m not coming from an entirely objective viewpoint. You’ve probably also heard various industry...

Great Barrier Reef suffered worst bleaching on record in 2016, report finds Higher water temperatures in 2016 caused the worst destruction of corals ever recorded on Australia's Great Barrier Reef, a study has found. Some 67% of corals died in the reef's worst-hit northern section, the ARC Centre of Excellence for Coral Reef Studies report said. The situation was better in the central section, where 6% perished, while the southern reef is in good health. But scientists warn recovery could be difficult if climate change continues. Coral bleaching happens when water temperatures rise for a sustained period of time. Image: ARC...

Carbon Footprint, ClimateChange, Environment, Science, Study -

Carbon footprint is the key metric on which corporate emission reduction plans are built and managed Although it is part of our everyday vocabulary, the term "carbon footprint" is not well understood by most people who use it. What it actually refers to is the total Greenhouse Gas (GHG) emissions, represented as tons of carbon dioxide equivalent (tCO2e), of a person, action, event, product, service or others. By definition, carbon footprint has to include GHG emissions from all sources. Carbon footprint assumes great significance today with the alarming rate of global warming and climate change. The cause-and-effect relationship between GHG...

Scientists warn increasingly rapid melting could trigger polar ‘tipping points’ with catastrophic consequences felt as far away as the Indian Ocean Photo: Temperatures in the Arctic are currently ‘off the charts’ at about 20C above expected. Arctic scientists have warned that the increasingly rapid melting of the ice cap risks triggering 19 “tipping points” in the region that could have catastrophic consequences around the globe. The Arctic Resilience Report found that the effects of Arctic warming could be felt as far away as the Indian Ocean, in a stark warning that changes in the region could cause uncontrollable climate change...
