The Guardian reports: A new study shows that oxygen levels in oceans have fallen 2% in 50 years due to climate change, which threatens future fish stocks and the habitat and behaviour of marine life. Related: Amitav Ghosh warns that the Bay of Bengal’s depleted fish stocks and huge dead zone signal a tipping point.
The Great Acceleration marks the phenomenal growth of the global socio-economic system, the human part of the Earth System. It is difficult to overestimate the scale and speed of change. In little over two generations –or a single lifetime –humanity (or until very recently a small fraction of it) has become a planetary-scale geological force.
Bill Laurance writes: An unprecedented spate of road building is happening now, with around 25 million kilometres of new paved roads expected by 2050. An ambitious new study that mapped all roads globally has found that roads have split the Earth’s land surface into 600,000 fragments, most of them too tiny to support significant wildlife.
Fidel Castro, the legendary Cuban revolutionary and politician who passed away on November 25th was known for his pioneering policies in health and education, but was equally committed to environmental issues. In this short talk given at the 1992 Earth Summit, Fidel described the global environmental crisis and identified its causes more powerfully than any other delegate.
From Nature Video: It’s a simple question: how many trees are there on Earth? The answer required 421,529 measurements from fifty countries on six continents. Their findings? The earth is losing 10 billion trees every year. Now this data has been combined to produce a stunning visualisation of earth as you’ve never seen it before.
Scroll.in reports: These timelapse videos were created with images of Landsat Satellite showing massive global transformations from 1984 to 2012 via Google Earth. Timelapse events include transformations such as the coastal expansion of Dubai, the retreat of the Columbia Glacier in Alaska, Saudi Arabian desert, Amazonian forest land in Brazil and Las Vegas urban growth.
Set in the world of a spoofed prescription drug commercial, Nature Rx offers a hearty dose of laughs and the outdoors – two timeless prescriptions for whatever ails you. This award-winning comedy series is a friendly reminder to us Earthly inhabitants what feels good and what is worth protecting once we take an adventure outdoors.
We face awesome global environmental challenges. Climate change, food production, overpopulation, the decimation of other species, epidemic disease, acidification of the oceans. Together, they are a reminder that we are at the most dangerous moment in the development of humanity… Now, more than at any time in our history, our species needs to work together.
Please don’t read this unless you are feeling strong. This is a list of 13 major crises that, I believe, confront us. From Trump to climate change, this multi-headed crisis presages collapse. And there’s no hope of exiting the ‘other side’ if political alternatives are shut down. Sorry to say that it’s not happy reading.
Andreas Malm writes: Mainstream climate discourse is positively drenched in references to humanity as such, human nature, the human enterprise, humankind as one big villain driving the train. Enter Naomi Klein, who in ‘This Changes Everything’ lays bare the myriad ways in which capital accumulation pour fuel on the fire now consuming the earth system.
Growing numbers of scientists have asserted that our planet might soon see a sixth massive extinction— driven by the escalating impacts of humanity. Others, such as the Swedish economist Bjørn Lomborg, have characterised such claims as ill-informed. We argue that the jury is in and the debate is over: Earth’s sixth great extinction has arrived.
Samar Halarnkar writes: In Nature in the City, her evocative exploration of Bangalore’s natural history, Harini Nagendra, says, “… residents engaged in practices such as placing a plate of warm rice (often with ghee added) outside to feed crows, leaving water baths for birds in the summer, and sugar and milk for ants and reptiles.”
On the eve of the American presidential election, where the two leading candidates offer little hope for climate action, it’s worth revisiting this hard-hitting 2006 article by Chad Harbach, who warned, “(Other countries) will do nothing until the United States demonstrates that a grand-scale transition to renewable energy can be achieved by big industrial countries.”
The Guardian reports: The number of wild animals on Earth is set to fall by two-thirds by 2020, which a new report attributes to an ongoing mass extinction. The analysis, the most comprehensive to date, indicates that animal populations plummeted by 58% between 1970 and 2012, with losses on track to reach 67% by 2020.
Aaron M. Ellison writes in Nature: Better data will not save elephants, rhinos or any other species. Countless individuals, institutions, governments, and multinational and non-governmental organizations have been collecting, assimilating and organizing such data for decades, essentially fiddling while our biological heritage burns… I suggest three crucial actions that scientists can take, beginning right now.
“The Great Barrier Reef of Australia passed away in 2016 after a long illness. It was 25 million years old.” So begins Rowan Jacobsen’s moving obituary for the world’s largest living structure. With 2,900 individual reefs and 1,050 islands, it’s larger than the United Kingdom, and it contained more biodiversity than all of Europe combined.
Dia Mirza writes: We cannot call this devastation of ecology and livelihoods ‘natural calamities’ anymore; it’s evident that there is a nexus of powerful people who are ignorant to the ramifications of their idea of “development” and “progress” that is gutting our forests, polluting our rivers and leading many states to a state of drought.
To fight climate change, a war-like mobilization a la McKibben is not necessary. Actually we are not at war at all. If we are, then it is we who are the aggressors, we are the enemy of nature. Then the first task for the transition is to end our aggression. We need only to withdraw.
Jason Hickel writes: The UN’s Sustainable Development Goals recognise the inherent tension between economic development and the planet’s ecology. It signals awareness that something about our economic system has gone terribly awry–that we cannot continue chewing through the living planet without gravely endangering our security and prosperity, and indeed the future viability of our species.
Yesterday, with protests over the Cauvery water dispute bringing Bangalore to its knees, many of the city’s techno-optimists found themselves stranded on its burning roads, like bunnies caught in headlights. It might just be another sign that ‘life as we know it’ is about to change forever, both in India and the world, writes Vijay Kundaji.
