Two poachers hold a pole with a heron perched on each. The birds, which are tied to the poles, are used to lure in other birds, such as the Indian Pond Heron, who are then illegally hunted by the man. The picture was taken from Chalan Beel in Rajshahi.
What is climate change? The planet's climate has constantly been changing over geological time. The global average temperature today is about 15C, though geological evidence suggests it has been much higher and lower in the past. However, the current period of warming is occurring more rapidly than many past events. Scientists are concerned that the […]
As well as rapidly reducing the carbon dioxide that we humans are pumping into the atmosphere in huge amounts, recent scientific assessments of climate change have all suggested that cutting emissions alone will not be enough to keep global temperatures from rising more than 1.5 or 2 degrees C. The Intergovernmental Panel on Climate Change […]
A research collaboration that included two scientists affiliated with Oregon State University found that 42 of Haiti's 50 largest mountains have lost all of their primary forest. Moreover, mountaintop surveys of vertebrates showed that species are disappearing along with the trees, highlighting the global threat to biodiversity by human causes. Along with the mass extinctions, […]
Few people in the world are aware their wellbeing may one day depend on a blue-blooded crab that looks like a cross between the facehugger from Alien and a gigantic louse. Fewer still realise this ancient creature now faces its greatest threat in more than 450m years. The American horseshoe crab outlived the dinosaurs and […]
Californians are embroiled in a debate over banning plastic products, including everything from straws to grocery bags. San Diego is considering prohibiting a particularly ubiquitous plastic product: expanded polystyrene (EPS)—better known as styrofoam—which is used widely in takeout food containers, cups, ice chests, and packing peanuts. (The trademarked product Styrofoam is slightly different than EPS.) […]
Plastic straws and cotton buds could be banned in England as part of the government's bid to cut plastic waste. Announcing a consultation on a possible ban ministers said 8.5bn plastic straws were thrown away in the UK every year. The prime minister said plastic waste was "one of the greatest environmental challenges facing the […]
We could be on the verge of triggering a series of cascading tipping points that result in the planet warming 4 or 5°C hotter than the pre-industrial benchmark. That, at least, is the view of a group of 16 climate scientists, who have spelled out a scenario in which sea levels would be 10 to 60 metres higher […]
The world has seriously underestimated the amount of heat soaked up by our oceans over the past 25 years, researchers say. Their study suggests that the seas have absorbed 60% more than previously thought. They say it means the Earth is more sensitive to fossil fuel emissions than estimated. This could make it much more […]
India's first fully organic state, Sikkim, won top prize in a UN-backed award on Friday, with organisers saying its policies had helped more than 66,000 farmers, boosted tourism and set an example to other countries. Sikkim was declared fully organic in 2016 after phasing out chemical fertilisers and pesticides and substituting them with sustainable alternatives. […]
