When it comes to preventing the worst of climate change, “the point of no return is no longer over the horizon,” United Nations Secretary General Antonio Guterres warned Sunday on the eve of a crucial round of intergovernmental talks at the UN’s annual climate summit.
New research warns that the earth may be approaching key tipping points, including the runaway loss of ice sheets, that could fundamentally disrupt the global climate system
However, only the concrete legislative and policy proposals expected in the coming months will show the extent to which the Commission is actually committed to heeding scientific recommendations for urgent and far-reaching transformational change.
Every day brings fresh and ever more alarming news about the state of the global environment. To speak of mere "climate change" is inadequate now, for we are in a "climate emergency". It seems as though we are tripping over more tipping points than we knew existed.

A new study led by Simon Fraser University's Dean of Science, Prof. Paul Kench, has discovered new evidence of sea-level variability in the central Indian Ocean.
Department of Fisheries and Oceans scientists say there's no point trying to save some of the native fish in a New Brunswick lake that may soon be deliberately poisoned.
A new study led by Auburn University researchers and published in the journal, Nature Climate Change, shows a four-fold increase in emissions of the potent greenhouse gas nitrous oxide—a major contributor to climate warming—in global streams and rivers.
Humans eat a lot of fish, in some areas of the world making up an essential part of our diet. Fishing can sometimes deplete fish populations to the point where the fish have difficulty reproducing and growing their numbers again. Establishing Marine Protected Areas (MPAs) that limit or eliminate ...
The narrative of the year will be if 2020 will be a turning point for the better or for the worse, says World Resources Institute president Andrew Steer. What stories should be watching out for?
The proportion of good quality surface water in China reached 74.9 percent at the end of 2019, up 3.9 percentage points compared to a year earlier, China's Ministry of Ecology and Environment said on Friday.
In 2019, the oceans reached higher temperatures than at any other point in recorded human history, according to a new analysis published on 13 January in Advances in Atmospheric Sciences (1). The new record demonstrates, unequivocally, the reality of global warming
Il existe en France, des terrains aménagés qui présentent une biodiversité insoupçonnée, abritant un écosystème bien plus riche qu'il n'y paraît : les prairies des aéroports. L'association Aéro Biodiversité fait le point sur ces zones qui symbolisent davantage la fuite en avant des émissions de ...
The pace of deforestation in the Amazon, coupled with last year’s devastating forest fires, has pushed the world’s largest rainforest close to a tipping point beyond which it will turn from a carbon sink to a carbon source.
The villagers walk down the grassy landing strip, past the wooden hut housing the health post and into the thick forest, pointing out the seedlings they planted along the way.
A meth Diagne points to a single tree submerged in the ocean. It is barely visible from the patch of land where he is standing, 50 metres away. The few branches emerging from the water mark the place where he proposed to his wife 35 years earlier.
There is growing evidence that Earth's systems are heading towards climate "tipping points" beyond which change becomes abrupt and unstoppable. But another tipping point is already being crossed—humanity's capacity to adapt to a warmer world.
Global biodiversity talks in China this year will highlight nature-based solutions that could meet one-third of Paris Agreement climate goal by 2030.
Last month, two graduate students from the Arnold Arboretum of Harvard University traveled to one of the most species-rich landscapes in the world: a remote strip of tropical rainforest at the narrowest point in the Central American country of Panama.
It's been a rallying cry for activists and a key talking point for diplomats. For decades now, 2 degrees Celsius (3.6 degrees Fahrenheit) of global warming has been viewed as a "do not cross" line in climate policy, a temperature at which cataclysmic and potentially permanent damage to the plane ...
It was on day 11, I think, that I stopped getting out of bed at all. I had already let my hygiene standards slip to the point that a large knot was starting to form in my hair. Later my mother would have to cut it out with scissors. She didn’t mind. We were all in the same boat.
When UN Secretary-General Antonio Guterres addressed the 193-member General Assembly last December, he focused on the smoldering climate crisis– pointing out that the last five years have been the hottest ever recorded.
Creating the conditions for sustainable seagrass restoration in Maputo and Inhambane bays “People can’t think of Inhaca without thinking about seagrass,” says Salamao Bandeira of Maputo’s Eduardo Mondlane University, knee-deep in the shallow waters on the seaward side of Maputo Bay, as he points ...
As extreme weather rocks the Southern Ocean, a tumultuous mix of carbon dioxide, winds and warming waters could reach an environmental tipping point
‘We understand the value of forests beyond the price tag of timber. We recognise that our forests are crucial for wildlife to survive.‘ Tesni Clare made some interesting points in the article ‘This is not a forest’, recently published in The Ecologist, not least about the importance of healthy f ...
Wind may have been pointed as the main culprit for the knocked down trees in all the attacks of hurricanes. However, a new survey was recently released of the damage in the Puerto Rican forests following the back-to-back hurricanes back in 2017. This particular survey highlighted the power of a ...
The ongoing spread of Covid-19, which is thought to have originated from a wet market in the Chinese city of Wuhan, is focusing increased attention on human interactions with wildlife. scientists pointed to pangolins as a possible source of the virus, although new research has now questioned thi ...
Recognizing the “immediate and dreadful” impact of the coronavirus, the UN chief urged everyone to “work together to save lives, ease suffering and lessen the shattering economic and social consequence”. At the same time, he observed that climate disruption is approaching “a point of no return” ...
There was literally a frog orgy in that one. There is no other way to describe it,” says Jules Waite, from the London Wildlife Trust, pointing at a pond in the Barbican wildlife garden, one of the few areas of London’s Square Mile whose inhabitants are not in lockdown.
New research evaluates claims that ocean aquaculture is the next sustainable and equitable food frontier, points to a balanced approach that includes land-based aquaculture as essential to achieve the Sustainable Development Goals.
Infrastructure megaprojects risk pushing the world’s remaining forests past a “dangerous tipping point” and making climate targets unachievable, a report says.
In an effort to understand where the bee population reside the most as well as to record different bee species and conserve them, researchers have created a global map that shows where bees live around the world. The map is supposed to act as a jump-off point for future bee-related research.
Scientists say a year in which almost 200 tundra lakes drained away could point to what’s in store for Canada’s North. Between 2017 and 2018, 192 lakes in northwest Alaska lost at least a quarter of their area as the permafrost that held them melted.
