Abrupt #climatechange

Do you feel that we have entered the sharp turn of the exponential curve of warming? That there is no chance of turning back?

Ok. It is likely you are right. Now, what to do.

We should make our last years as painless as possible. Let's go into degrowth by stopping the waste and sharing what is left.

The private auto is probably the best example of waste. Not just because it is an anti-social wasteful consumer product. But because it promotes sprawl and growth. Let's abolish it.

#Heat or #Emissions?

The idea of reducing human carbon emissions is to reduce greenhouse effect and thereby reduce the temperature of the biosphere.

There are two ways to reduce human emissions. Stop producing them, or get energy from non-carbon sources.

The main problem with getting energy from non-carbon sources is that there is nothing about them that curbs growth. And as long as there is growth in human activity, there will be more heat. That heat will release stored natural carbon and generate more emissions, undoing all efforts.

We can address heat directly, and reduce human emissions at the same time by reversing growth, degrowth.

There is some low-hanging fruit for degrowth. The auto and sprawl system is very wasteful. It could be quickly and severely tightened up by abolishing the private auto. Along with this, comprehensive health care and education would accelerate falling birth rates.

Renewables and electric cars will increase carbon emissions

Cars promote sprawl. Sprawl wastes energy. Buildings are spread out. Each one needs separate heating, cooling, lawn-care, parking, sewer lines, roads, etc.

Sprawl is sacred to capitalism because it means growth. Even if that growth is mostly waste, capitalism doesn't care. More cars, more babies, more leaf-blowers... that is the goal.

All this waste. The people crowing about "renewables" are not suggesting ending the waste. They just want more fuel on the fire. To test this statement, ask them if they will openly advocate #freetransit as part of their "keep it in the ground" mantra.

There is nothing inherent to renewables that leads to degrowth. In fact, renewables contain fossil-fuels and depend on the fossil-fuel created system.

So, since renewables do not reduce growth, growth will continue in the new "green economy." Growth generates heat and heat melts clathrates. The carbon emitted from the clathrates will overwhelm any emission reduction from the renewables.

It can be said then, that renewables increase carbon emissions.

Melting soil in cold regions releasing long-held CO2

ScienceAlert: "That's an amount comparable to all the emissions from the US commercial sector in a single year.

The chief reason for the greater CO2 release was that as Alaska has warmed up, emissions from once frozen tundra in winter are increasing - presumably because the ground is not refreezing as quickly.

"The soils are warmer deeper, and as they freeze in the fall, the temperature of every soil depth has to come to zero before they hard freeze," Commane said."

Miles of Ice Collapsing Into the Sea

The New York Times: "A rapid disintegration of Antarctica might, in the worst case, cause the sea to rise so fast that tens of millions of coastal refugees would have to flee inland, potentially straining societies to the breaking point. Climate scientists used to regard that scenario as fit only for Hollywood disaster scripts. But these days, they cannot rule it out with any great confidence."

Adding up the feedbacks, biosphere goes over 22C by 2027

Nature Bats Last: "In total, Carana ends up with 10.02 C above baseline by mid-2026, or about 23.5 C. That’d be the highest global-average temperature on this planet during the last 2,000,000,000 years. Taking a conservative approach at every step, I conclude “only” an 8.71-degree rise in temperature by mid-2026. As a result, I conclude global-average temperature at that time will be about 22.2 C (13.5 C + 8.71 C). This is barely above 22 C, the temperature at which Earth has most commonly found itself during the last 2,000,000,000 years. I suspect it’s more likely, based on the conservative journal literature, that Earth will hit about 23 C in a decade. There is no reason to expect Earth to start cooling until the heat engine of civilization is turned off and dozens of self-reinforcing feedback loops are inexplicably reversed."

What's so great about #freetransit?

  • saves money for riders
  • saves money for city as a whole
  • reduces bureaucracy
  • immediate reduction in energy use
  • easy to implement
  • people love it
  • makes buses more efficient
  • leads to urbanization and falling birth rate
  • reduces incentives for sprawl
the list goes on and on and on...

Fast track to reduce #heat

Social and corporate media are full of ideas for human designed carbon-capture and renewable energy sources.

What is not understood is that according to physics, human activity generates heat. This happens no matter what the fuel is. So, if that activity is building a solar array, or a carbon-capture device, that activity generates heat.

The only way to reduce heat is to reduce activity.

One way is to address the biggest problems first. Ten percent of humans use half the energy. A lot of this energy is wasted by cars sitting in traffic jams. But cars are not even necessary. Humans have been on earth 200,000 years, but cars less than 150 years. We don't need them. There are many other benefits to ending cars besides the obvious reduction of fuel waste.

By abolishing the private auto, we can:

  • reduce energy waste
  • take away the major driver of sprawl and growth
  • reduce inequality of energy use
  • make cities attractive
  • free up money for education and healthcare to make birth rates fall
  • turn suburbs into permaculture carbon sinks

Natural carbon-capture destroyed by logging

World Economic Forum : "Forests have been removing carbon dioxide from the atmosphere and storing carbon for more than 300 million years. When we cut down or burn trees and disturb forest soils, we release that stored carbon to the atmosphere. Since the start of the Industrial Revolution, one-third of all carbon dioxide emissions to the atmosphere from human activities have come from deforestation."

Our main problem is #heat, some scientists predicting human extinction

Arctic News : "How much could temperatures rise? As above image shows, a rise of more than 10°C (18°F) could take place, resulting in mass extinction of many species, including humans."
