From BuzzFeed: The 2010s will likely lock down the record for the hottest decade so far. The 10-year stretch boasted many of the most expensive and destructive catastrophes ever. Here’s a review of six of the most devastating climate-records we broke this decade. Also, a short video featuring expert views on looming climate tipping points.

Ayushi Uppal writes: While the concept of Anthropocene remains contested, there is consensus on the human-led changes to the climate and the need for intervention. Humanity must create a pathway from a possible ‘Hothouse earth’ to a ‘Stabilized Earth’ state, where human activities create biogeophysical feedbacks that sustain the Earth System within the planetary threshold.
Elaine Brum writes: Believing the Amazon is far away, on the periphery, when the only chance of controlling climate change is to keep it alive, reflects ignorance of continental proportions. Our eyes have been contaminated, distorted, colonised. The forest is at the very core of all we have. This is the real home of humanity.
From BBC: “The climate math is brutally clear: While the world can’t be healed within the next few years, it may be fatally wounded by negligence until 2020,” said Hans Joachim Schellnhuber, founder of the Potsdam Climate Institute. The sense is that the end of next year is the last chance saloon for climate change.
From NewsClick: The Anthropocene Working Group (AWG), a panel that consists of 34 scientists and academics, has voted in favour of making the Anthropocene a formally defined geological unit within the official geological time scale. The term ‘Anthropocene’ denotes the current geological period, where many conditions and processes on Earth are altered by impacts of human activities.
By Dahr Jamail: Permafrost, or frozen soil in the Arctic is now thawing so fast that scientists are literally losing their measuring equipment. This is due to the fact that instead of there being just a few centimeters of thawing each year, now several meters of soil can become destabilized in a matter of days.
To keep this kind of growth going, we need to tap more resources, which is beyond the Earth’s capacity. Till now the growth was possible because we thought resources are abundant. But today we know that we will have to experience a serious crisis in the next half century, depending upon how we use resources.
From The Revelator: In the year ahead we all need to stand up and let our elected officials and unelected corporate power-brokers know what really matters to us and to the planet. We need to demand transparency and the truth, rapid change, renewed protections for imperiled species and a commitment to sustainability on all fronts.
From The Guardian: On the eve of the UN’s annual climate conference, many experts believe the world may no longer be hovering at the edge of destruction but has probably crossed a crucial point of no return. Climate catastrophe now looks inevitable; we’ve simply left it too late to hold global temperatures to under 1.5C.
David Wallace-Wells writes: Brazil’s newly elected president Jair Bolsonaro just might test the proposition that no individual matters all that much to the climate. He plans to open the entire Amazon rainforest to agricultural development — the industrial-scale felling of trees, which, will release into the atmosphere all the CO2 they have stored inside them.
The recent Special Report by the IPCC was widely described as giving a stark warning about risks faced by humanity if climate change is not dealt with urgently. What exactly does this imply, and how reliable is this document? We present analyses by Michael Mann, Richard Heinberg, Ratheesh Pisharody, Adam Markham, Kevin Anderson and Padmini Gopal.
We’re on track for four degrees of warming, more than twice as much as most scientists believe is possible to endure without inflicting climate suffering on hundreds of millions or threatening at least parts of what we call, grandly, “civilization.” The only thing that changed is that the scientists, finally, have hit the panic button.
A Special Report on Global Warming has been released today by the IPCC, considered the international benchmark on climate change. Ahead of it, Donald Brown reviewed three independent studies which show that climate change is a much more urgent and serious threat than indicated by past IPCC reports, and examines the ethical questions they raise.
A research-paper concluding that climate-induced collapse is now inevitable, was recently rejected by an academic journal, citing the emotional impact that it might have on readers. The paper offers a new framing to make sense of the disaster we face, called “deep adaptation.” It has now been released online by the author, Prof. Jem Bendell.
Douglas Rushkoff writes: (The billionaires I recently met) were preparing for a digital future that transcends the human condition altogether while insulating themselves from a very real and present danger of climate change, rising sea levels, mass migrations, global pandemics and resource depletion. For them, the future of technology is really about just one thing: escape.
It’s no longer possible to separate the health of the planet from the health of its people. Disease patterns are changing as the climate does, and human health is at risk from loss of biodiversity, depleted water supplies, environmental toxins, and collapsing food systems. From this realisation has come a new research field: planetary health.
From Grist Magazine: It’s the hottest month of one of the hottest years in the history of civilization, and the world is being battered by extreme weather events – unprecedented heatwaves in japan, wildfires in Greece and the Arctic Circle, and flooding in Philippines and Laos, where a dam was washed away, forcing thousands to flee.
Kerry Emanuel writes: There are strong cultural biases against discussion of ‘tail risk’ in climate science; particularly the accusation of “alarmism”. Does the dictum to tell “the truth, the whole truth, and nothing but the truth” not apply to climate scientists? If we omit discussion of tail risk, are we really telling the whole truth?
‘As the waters rise,’ Jeff Goodell writes, ‘millions of people will be displaced, many of them in poor countries, creating generations of climate refugees that will make today’s Syrian war refugee crisis look like a high school drama production.’ There’s no longer any doubt that the rise in global sea levels will reshape human civilisation.
Limiting global warming to 1.5C requires strictly limiting the total amount of carbon emissions between now and the end of the century. However, there is more than one way to calculate this allowable amount of additional emissions, known as the “carbon budget”. In this article, Carbon Brief assesses nine new carbon budget estimates released recently.
