2018/09/26: The energy lessons here are many.
The industrial whale business tells us, for example, that human economies don’t respond to the depletion of any commodity with alacrity. Or reason.
The discovery and mining of petroleum could have prevented the slaughter of nearly three million whales in the 20th century, but it didn’t.
Just because a substitute exists — kerosene for whale oil or renewables for some fossil fuels — doesn’t mean the market will use them for conservation purposes.
The factory ship and its fleet could not exist without fossil fuels, which powered the whole operation and allowed for long-duration storage of whale products by running freezers (for meat) and processing whale oil so it would not become rancid.
The prospect of regulating whaling also provided whalers with an extra incentive to catch as many whales as they could before the regulations came into force.
Economists now call this perverse response to resource depletion the “green paradox.”
German economist Hans-Werner Sinn, for example, argues that society is playing out the same game with fossil fuels.
policies aimed at reducing future demand for fossil fuels could backfire by inducing resource owners to bring forward their extraction plans, thus accelerating global warming. In fact most oil-exporting nations such as Canada want to build more pipelines and export more carbon-heavy fuels as quickly as possible.
Technological innovations don’t retire resources or lead to conservation but increase production so as to increase revenue.
The widespread expectation that new technologies will help societies overcome environmental problems reflects the still common assumption that technologies will principally have the consequences intended by those who develop and/or deploy them.
Real change, he writes, “may require active suppression of fossil fuel use, such as by restricting the amount of fossil fuel that can be extracted.”
2018/09/26: fellows have been charged with waging what the group calls a “massive youth intervention in the 2018 midterm elections.”
Sunrise isn’t the only youth-led group pushing for a green wave this election season.
she was determined to get voters thinking about the impact they can have on the planet where we all live.
“Their individual decisions as voters affect the rest of the world,” Chua said. “I’m part of the rest of the world.”
2018/09/17: in recent years, research has made it increasingly clear that — after an 11,000 year period of relative stability — the climate has become destabilized by human emissions of carbon pollution, putting us on a path towards steadily rising temperatures throughout the century.
In this business-as-usual case — without more drastic action taken to cut the world’s greenhouse gas emissions — we will continue warming more than 50 times as fast as the planet was (slightly) cooling in the past 5000 years.
And it’s not just global temperatures that are being destabilized, so are sea levels. That’s clear from the Trump administration’s own November 2017 National Climate Assessment.
This “authoritative assessment of the science of climate change” explains that sea levels do not stop rising this century. Even worse, if the country’s do-little climate policies continue — or, worse, actually get rolled back as they are under Trump — then the rate of sea level rise will actually speed up.
our current climate is near the very edge of stability, according to a major new study by 16 leading climate scientists.
We are pushing the planet toward an irreversible “Hothouse Earth” — catastrophic warming of 9°F or more with ultimate sea level rise of up to 200 feet. And that study warns we are much closer to the “point of no return” than most people realize.
2018/06/27: We are witnessing a massive transition in Value Creation from the means of production to the means of Market Production and Curation.
Take for example Uber – here the taxi driver is a bare transitionary commodity and interchangeable. The real value creation instrument is Uber which creates, curates the market – this process now extends from Retail – Amazon – to Manufacturing, AliBaba. This reality signals a great transfer of value creation from the relatively distributed means of production to the massively globally centralised & privatised means of market making & marker curation. The implications of this are massive for inequality and scaling of precarious citizenship.
what is being disrupted is not the plumber or craftsmen but the middle classes – the management, administrative and intermediary skills.
Our Governance model is broken, we live in a ‘systemocracy’ – a world of massive inter-dependency yet we are holding on to 19th century versions of governance. This creates the illusion of sovereignty & supremacy – acting as a denial of the complexity we must confront.
2018/08/14: none of this is inevitable, and one of the main barriers between us and a stable planet - one that isn’t actively hostile to human civilization over the long term - our economic system.
dramatically reimagine sectors like transportation and agriculture “at very fast rates.”
humans have to create their own negative feedback mechanisms so the Earth can maintain a stable level of carbon in the atmosphere. That means expanding and repairing the Earth’s natural “carbon sinks,” like big forests that can effectively suck emissions out of the atmosphere and store them naturally.
For high-emitting countries like the U.S., Steffen says the first step to avoiding planetary apocalypse is basically self-evident: “absolutely no new fossil fuel developments. None. That means no new coal mines, no new oil wells, no new gas fields, no new unconventional gas fracking. Nothing new. Second, you need to have a rapid phase-out plan for existing fossil fuels,” starting with coal
2018/08/20: Nearly a quarter of the Northern Hemisphere's landmass sits above permafrost. Trapped in this frozen soil and vegetation is more than twice the carbon found in the atmosphere.
New data from two Arctic sites suggest some surface layers are no longer freezing. If that continues, greenhouse gases from permafrost could accelerate climate change.
in a region where temperatures can dip to 40 degrees below zero Fahrenheit, the Zimovs say unusually high snowfall this year worked like a blanket, trapping excess heat in the ground. They found sections 30 inches deep—soils that typically freeze before Christmas—that had stayed damp and mushy all winter. For the first time in memory, ground that insulates deep Arctic permafrost simply did not freeze in winter.
Could a thaw of permafrost begin decades sooner than many people expect in some of the Arctic's coldest, most carbon-rich regions, releasing trapped greenhouse gases that could accelerate human-caused climate change?
2018/09/11: The future of food in the world will depend on what Africa does with agriculture.
one recent study estimates that elevated carbon dioxide (co2) could cause an additional 33.6 million in sub-Saharan Africa to become zinc deficient and another 16 million protein deficient by 2050 if levels continue to increase unabated. Today, an estimated 60 million African children under 5 years old are stunted due to inadequate nutrition.
Africa contributes little to global greenhouse gas emissions, but is one of the most vulnerable regions to climate change due to its weak ability to adapt to related weather impacts, as well as its dependence on rain-fed agriculture.
A range of actions across sectors is needed to ensure the sustainability of Africa’s food and land use systems - and the health and well-being of millions of children.
2018/09/12: the world needs more swamps.
wetlands are extremely efficient at pulling carbon dioxide out of the atmosphere and converting it into living plants and carbon-rich soil.
If ecosystems, particularly forests and wetlands, did not remove atmospheric carbon, concentrations of carbon dioxide from human activities would increase by 28 percent more each year.
A deadly positive feedback from melting permafrost is extremely bad news - and it will not even be noticed by most of the political class.
An international team of U.S. and German researchers found that abrupt thawing more than doubles previous estimates of permafrost-derived greenhouse warming. Even in the scenario where humans reduced their global carbon emissions, large methane releases from abrupt thawing are still likely to occur.
2018/07/16: the first ever report to quantify the growing risks and assess the opportunities of the global cooling challenge.
There are over 1.1 billion people globally who face immediate risks from lack of access to cooling. Cooling underpins the ability of millions to escape poverty, to keep our children healthy, vaccines stable, food nutritious, and our economies productive. Access to cooling is now a fundamental issue of equity, and as temperatures hit record levels, this could also mean the difference between life or death for some.
These risks are both a development and climate change issue, as they pose challenges for the health, safety, and productivity of populations across the world – especially countries in Asia and Africa where access gaps are the largest. Yet this challenge also offers business and entrepreneurs the opportunity of major new consumer markets which want super-efficient, affordable technologies to meet their cooling needs.
In a world facing continuously rising temperatures, access to cooling is not a luxury – it’s essential for everyday life. It guarantees safe cold supply chains for fresh produce, safe storage of life-saving vaccines, and safe work and housing conditions-
2018/08/01: For most people who work on climate change policy, targets have been aspirational, something we’re working towards. California has changed all that by announcing that its first key climate policy milestone is now in our rear-view mirror, more than three years early.
The deadliest place on the planet for extreme future heatwaves will be the north China plain, one of the most densely populated regions in the world and the most important food-producing area in the huge nation.rnrnNew scientific research shows that humid heatwaves that kill even healthy people within hours will strike the area repeatedly towards the end of the century thanks to climate change, unless there are heavy cuts in carbon emissions.rnrn"This spot is going to be the hottest spot for deadly heatwaves in the future," said Prof Elfatih Eltahir, at the Massachusetts Institute of Technology, US, who led the new study. The projections for China's northern plain are particularly worrying because many of the region's 400 million people are farmers and have little alternative to working outside.rnClimate change to cause humid heatwaves that will kill even healthy peoplernRead morernrn"China is currently the largest contributor to the emissions of greenhouse gases, with potentially serious implications to its own population," he said. "Continuation of current global emissions may limit the habitability of the most populous region of the most populous country on Earth."rnrnThe new analysis assesses the impact of climate change on the deadly combination of heat and humidity, which is measured as the "wet bulb" temperature (WBT). Once the WBT reaches 35C, the air is so hot and humid that the human body cannot cool itself by sweating and even fit people sitting in the shade die within six hours.rnrnA WBT above 31C is classed by the US National Weather Service as "extreme danger", with its warning stating: "If you don't take precautions immediately, you may become seriously ill or even die."
The monetary stakes, it turns out, are not the biggest obstacle to rational action on global warming.
