SNIPPET:

A Message Of Hope

If you haven’t seen the Ocasio-Cortez video yet, take 7 minutes out of your busy life to watch it now. It’s not a polemic, it’s a vision, one that we in America can choose to embrace. If we do, we can rightfully claim to be a nation of leaders. If not, we are risking all for the sake of a few. It’s our choice and it begins with electing leaders who believe in the common good, not those 😈👹💵🎩🏴‍☠️ who profit from promoting special interests.

The Green New Deal is consistent with the ideals America was founded upon. To attack it is to deny the very essence of our American heritage.

Agelbert NOTE: What's it going to be, 'Busness as Usual' short term 'greed is good' profit over people and planet or AOC's Vision of a Viable Biosphere defending USA 

If the 'greed is good' Capitalist Cretins win, the following future is GUARANTEED:

   It's Time to Transform the Tax Code and Implement a Green New Deal

HOWIE HAWKINS, POPULAR RESISTANCE

Tax policy has favored the wealthy under both parties, but the Trump administration has brought this tax corruption to new levels. We need to transform tax policy to build the working class base of the economy, shrink the wealth divide and confront the climate crisis. More progressive and ecological taxation is essential to fund the ecosocialist Green New Deal.

This week, Sanders made a rather stunning proposal on behalf of himself and his supporters: “We say to Donald Trump and the fossil fuel industry that climate change is not a hoax but is an existential threat to our country and the entire planet — and we intend to transform our energy system away from fossil fuel and into energy efficiency and sustainable energy and, in the process, create millions of good paying jobs. All of us have a moral responsibility to make certain that the planet we leave to our children and grandchildren is healthy and habitable.”

Chevron’s Fig Leaf Part 4: Carbon Engineering’s Only Market Is Pumping More Oil  >:(

April 19th, 2019 by Michael Barnard

SNIPPET:

Carbon Engineering recently garnered $68 million in investment in its air-carbon capture technology from three fossil fuel majors. This is part 4 of the 5 article series assessing the technology and the value of the investment.

The first piece summarized the technology and the challenges, and did a bottoms-up assessment to give context for what Carbon Engineering is actually doing. The second piece stepped through Carbon Engineering’s actual solution in detail. The third piece returned to the insurmountable problem of scale and deals with the sheer volume of air that must be moved and the scale of machinery they have designed for the purpose. This fourth article will look at the market for air carbon capture CO2 and assess why three fossil fuel majors might be interested. The final article will address the key person behind this technology and the expert opinions of third parties.

There is zero net removal of CO2 from the atmosphere if air carbon capture is used for enhanced oil recovery.

Full article:

https://cleantechnica.com/2019/04/19/chevrons-fig-leaf-part-4-carbon-engineerings-only-market-is-pumping-more-oil/

Agelbert COMMENT: This is a well thought out, thoroughly researched and accurately presented series of articles. Thank you, Michael Barnard 💐, for telling it exactly how it is.

I've thought about the Carbon Dioxide issue for several years. I have always questioned the motives behind the hydrocarbon industry cheerleading CO2 capture and sequestration.

IMHO, after looking at this from several reality based angles (unlike the unreality based happy talk pushing MO of the 🦕😈🦖 fossil fuelers), the fact that the best present day technology to keep the CO2 concentration down (which is used in Nuclear Submarines, which are forced to surface every six months because they cannot keep CO2 below 8,000 PPM after that time period) cannot get CO2 levels anywhere near 5,000 PPM, never mind the 350 PPM we desperately need to get back to in order to avoid the worse effects of the Sixth Mass Extinction now in progress from excessive GHG emissions, EVIDENCES THAT the proposed CO2 reduction technology, euphemistically called "capture and sequestration" technology, is a fraud. 👎

IOW, all the technofixes out their refuse to admit that the GOAL here is NOT to keep the Hydrocarbon Industry profitable. The GOAL is 350 PPM, period. Anything else is simply wishful thinking.

So, IMHO, we have to resort to biological solutions involving rapid photosynthesis.

I researched this thoroughly. There is no plant life that can beat algea at rapid photosynthesis, which is the sine qua non requirement for reaching the 350 PPM goal, but algae is so hydrophylic (water loving) that too much energy is required to dry it for storage. 👎 No, passive solar energy will not work to dry algae. That has been tried unsuccessfully. Also, algea can grow rapidly only in a very narrow range of the biosphere.👎 Algea is not the answer.

🤔👨‍🔬

But, there is a floating plant, the tiniest angiosperm (flowering plant) known to science, that can do the job of rapid photosynthesis that we need on a planetary scale. 🌍🌎🌏🌞

► It is extremely hardy.

► It grows in nearly all areas of the planet, with a longer growing season that any other plant life form except phytoplankton.

 ► It doubles it's mass every 48 hours or so, depending on the availability of Sunlight, Carbon Dioxide and cheap fertilizer like pig feces.

► It is tiny, but not microscopic. It can easily be harvested without heavy machinery.

► Unlike microscopic algae, Drying these tiny plants with passive sunlight is also easily done.

► It is easily stored.

► It can even be used as animal feed AND supplemental nutrition for humans too.

► It has been used to clean ponds and lakes of toxic heavy metals. When used for this pupose, it becomes poisonous and must be treated as hazardous waste.

The common name is Duckweed, of which there are a number of species of floating plants. My favorite is Lemna minor ✨🌞

The science based case for a planet scale Lemna minor project has actually been made by evidence of a floating plant when the Arctic had shallow freshwater seas (millions of years ago). Scientists now believe a rapid cooling that took place at that time, even though the CO2 level was even higher then than it is today, was directly caused by the proliferation of Azolla floating plants in that sea. They rapidly lowered the CO2 levels, sinking when they died and being replaced by others, until ice formed over them. They cooled ALL of Earth's atmosphere from a CO2 PPM concentration that was higher than the one we are saddled with now.

"This freshwater surface layer allowed Azolla to repeatedly spread across the ocean surface forming mats of vegetation during a succession of episodes called the ‘the Arctic Azolla Event‘. The event lasted for almost a million years from about 50 to 49 million years ago."

Arctic Azolla Event - You can watch a Powerpoint presentation about the Arctic Azolla Event on this page. - One of the most remarkable discoveries about Azolla came in 2004. A scientific expedition to the North Pole showed that this remarkable plant had a massive effect on the Earth’s climate 50 million years ago.

It happened before. We can make it happen again. 💫

True, we do not ⌛ 🌡️ have a  million years or so to do the job, but we don't need more than a few decades to scale this biological CO2 sequestering program to all desert areas of the planet on gigantic shallow (a little more than one meter of depth is all you need) artificial lakes.

True, the fact remains that this aquatic family of plants, like Azolla, requires plenty of water, a resource that is mostly not available in desert areas. THAT, however, is a problem that human engineering CAN solve, unlike trying to get CO2 down to 350 PPM with technology that cannot even keep it below 5,000 PPM!

If Azolla in the Arctic freshwater sea 50 million years ago, a tiny portion of the planetary surface, could cool down an overheated atmosphere with a much higher CO2 PPM concentration than we have now, there is no rational excuse for not duplicating that event with a crash program to grow Duckweed in all the non-arable land areas of the planet. 👍👍👍

The Hydrocarbon Hellspawn have NOTHING to offer. They CANNOT DELIVER an atmospheric CO2 PPM reduction to 350 PPM. All they can do is bill us for technofixes that allow them to profit over planet while the CO2 concentration continues to rise!


Let's stop being crazy and stupid. Let's GO WITH A PROVEN BIOLOGICAL CO2 reducing solution.




Proof of concept graphic (obviously the ponds will have to be at least a million times bigger than those shown and made from natural materials with Renewable energy powered machinery):


This video pushes Duckweed as a biofuel source. I post it so you can see how fast it grows. I still believe we certainly can use Duckweed for biofuels, but the most vitally important use we need to make of this fast growing plant is the reduction of CO2 from our atmosphere 🔊 NOW, before the biosphere we depend on is cooked! ☠️ 😱


 The Fossil Fuelers 🦖 DID THE Clean Energy  Inventions suppressing, Climate Trashing, human health depleting CRIME,   but since they have ALWAYS BEEN liars and conscience free crooks 🦀, they are trying to AVOID   DOING THE TIME or   PAYING THE FINE!     Don't let them get away with it! Pass it on!

Agelbert NOTE: There is a lot of important information in this post quoted from Radio Ecoshock. It may be too much for the average reader to handle in one sitting. I recommend you just listen to the hour long podcast, then return here (or directly to Radio Ecoshock) when you have some spare time to watch the posted videos.

This forum post, like all posts here at the Renewable Revolution forum, has a link. Just copy it so you can return to it without a search through this topic thread.

Also, there are many videos on this topic thread (i.e. "Global Warming is WITH US") that irrefutably reveal the existential threat to humanity of Catastrophic climate change.

The Burning Question

Posted on April 17, 2019, by Radio Ecoshock
 
As the second largest land mass on the planet, Canada is warming at twice the global average. The vast Canadian Arctic is heating three times average. The impacts spread around the world. Leading scientist Dr. Nathan Gillett explains a new climate change report from the Government of Canada. Then Canadian climate scientist Paul Beckwith joins me to thrash through scary new science: the limits before extinction, ocean drivers of our lives, and why weather has gone rogue.

I’m Alex Smith. This is Radio Ecoshock.

🔊 Listen to or download this Radio Ecoshock show in CD Quality (57 MB) or Lo-Fi (14 MB)


CANADA CLIMATE SCIENCE

Radio Ecoshock has listeners all over the world, so I try to keep a global perspective. But now we need to talk about the second largest country in the world: Canada. After 10 years of being shut out from talking with federal government scientists, during the Harper regime, today I talked with climate scientist Nathan Gillett from Environment and Climate Change Canada. He told us the rate of warming in Canada was double the world average.

You may think global warming would be good for colder places like Canada. A new report from the Government of Canada warns against that myth. The country has already warmed about twice the world average, and will continue to heat up faster than the rest of the planet during this century and beyond. Scientists project more flooding, more wildfires, extreme heat events, strange winters, and damage to the seas surrounding Canada’s vast coastline.

Here to explain is one of Canada’s top climate scientists. Dr. Nathan Gillett received his PhD in Atmospheric Physics from the University of Oxford. He is a Coordinating Lead Author of the chapter on human influence on climate, in the upcoming IPCC Sixth Assessment Report. Nathan leads research into climate impacts for the Canadian government.


Dr. Nathan Gillett

With my next guest Paul Beckwith in mind, I asked Dr. Gillett when the sea ice might be gone in summer, the so-called “Blue Ocean Event“. He suggested that might come around the year 2050. As you will hear, Paul Beckwith ✨ thinks the Blue Ocean Event will come much sooner, possibly in the next decade.

The rest of the world tends to think about “Canada” and “cold winter” in the same sentence. But winter here has already changed. In fact, most of the new warming from climate change has come in the winter. That means earlier snow melt, different conditions for spring rivers and flooding, possibly a longer growing season, and difficult changes for both animals and plants. Although the Canadian Arctic is warming at three times the global mean average temperature, southern Canada is warming at twice the rate.

Even so, the new report “Canada in a Changing Climate: Advancing our Knowledge for Action” warns parts of the country could experience shortages of freshwater. As an old Canadian growing up with so many lakes and rivers, that seems hard to believe. How could some Canadians face water shortages, despite annual precipitation going up?

I always remember our Canadian fire expert Mike Flannigan telling us on Radio Ecoshock that thin soils in Canada’s north can dry out to a tinder state in just three days. You could have rain, then three days of heat, and then poof! forest fires. We are already doing emergency fire planning here in the West.

You can watch a video of Nathan Gillett explaining his work here.



 
=============================================================================================

A FLOOD OF DANGEROUS NEW SCIENCE – PAUL BECKWITH

In the month of March 2019, the Arctic was 20 degrees hotter than it should be. Under that massive heat, sea ice is at a record low. Unprecedented Arctic warming is distorting weather in the Northern Hemisphere where the majority of humans live. Extreme weather has brought unhappiness, vast damage, and death. In this new climate age, the idea of progress has been replaced by constant efforts to recover.



In the past 3 months, I brought you the science of climate change direct from specialists publishing top papers. To draw it together, we need a generalist with climate expertise. We need Paul Beckwith. Paul has two Masters degrees. He often teaches climate science at the University of Ottawa. But his tireless effort to teach extends to the Internet. On You tube, Paul Beckwith is by far the biggest teacher of climate science to the world via You tube.

KEY INDICATORS OF ARCTIC CLIMATE CHANGE

We have a new paper, published April 8th by scientists in Alaska and Denmark. The title is “Key Indicators of Arctic Climate Change: 1971–2017”. Lead author Jason Box said “The Arctic system is trending away from its 20th century state and into an unprecedented state, with implications not only within but beyond the Arctic.”

Those scientists seemed surprised that temperature was the “smoking gun” for all the changes in the Arctic. (That seems obvious to me, what about you?) On the other hand, the fastest moving ice body on Greenland, The Jakobshavn glacier, has not only slowed down but is gaining ice mass. Paul says that is a temporary phenomenon, and who knows – maybe the glacier as it moved got snagged on some land way down below.

THE LINGERING COLD BLOB IN EASTERN NORTH AMERICA

Could that slowdown in part of Greenland be connected to the long-lasting cold and snow in the North East, including in Paul’s hometown in Ottawa? Paul says he had “a glacier” of ice remaining in his front yard, and we talk about the cold blob of air hovering over eastern North America, punctuated by storms. Here’s his video on that.


The public is so focused on global warming, it is pretty hard to convince people that a depressing cold winter could also be influenced by climate change. Nobody wants to go protest in the cold, but when it’s hot, they want to go outside and enjoy themselves. So far, there doesn’t seem to be a good time to protest. Were there climate school strikes in Ottawa or in Quebec?

Some people think Paul is a radical climate scientist. But really the whole upper echelon of climate research institutes are now radical about climate change. They are practically screaming out warnings of disaster, and we talk about some of those in this interview. But despite Paul’s efforts and mine, the public still isn’t engaged. People fly all over the place, and dream about their next pickup truck with a big gas engine. It is an addictive dream. Do you expect a rapid awakening, or more years of deadly greenhouse gas emissions?

We just had another freak April storm where the temperature was expected to drop 60 degrees in Denver, going from 70 or 80 Fahrenheit to blizzards. Yet another very heavy snow storm hit Montana and Nebraska in April. They are calling it a “bomb cyclone“.

Then we had flooding in the mid-west of the U.S., right in key food production areas. I think that was a major event with long-lasting consequences. Mainstream the media forgot that story already. Of course, Paul Beckwith has a new video about that.


Why is weather in the Northern Hemisphere so weird?

SIMULTANEOUS 🔥🔥 HEAT 🌡️ WAVES – NEW INTERVIEW COMING UP!

I want to tell listeners about brand new science, still awaiting publication. It announces a new phenomenon in the world: simultaneous heat waves across the planet. Martha Vogel, a climate researcher from ETH Zurich, just presented the findings at a European Geosciences Union press conference in Vienna in the first week of April. Studying heat waves from 1958 to 2018, they discovered that only since 2010 has modern planet Earth experienced multiple extreme heat waves at the same time. For example extreme heat in the Mediterranean might also strike in the Arctic and Russia or North America at the same time. Transcontinental heat: that has terrible implications for food production and a lot more.

My interview with scientist Martha Vogel should be next week on Radio Ecoshock

THE NEW 2018 CLIMATE REPORT FROM THE WORLD METEOROLOGICAL ORGANIZATION (WMO)
Paul discusses this report in two videos, starting with this one.


You can read that full report “WMO Statement on the State of the Global Climate in 2018” as a .pdf online here.

According to the WMO, in 2018 the heat content of the upper levels of the ocean were the highest ever recorded.
That is so dangerous! 😨

People get confused about the difference between ocean HEAT absorption (which is 93%) to greenhouse gas absorption by the sea, (which is 25%). Since 93% of our excess heat goes into the ocean, that means only 7% is causing the disruption we are feeling now!

If the ocean takes less carbon dioxide, as scientists predict, then not only will there be more greenhouse gases, but those gases will remain longer, and become a larger share of our actual emissions in the atmosphere.

If so, we have to cut off fossil fuels and other greenhouse sources pretty well immediately. Strange to say, but our industrial culture may depend on ocean chemistry and ocean physics.

In a BBC article about the World Meteorological Report for 2018, Australian climate scientist and Professor Samantha Hepburn said:

“We know that if the current trajectory for greenhouse gas concentrations continues, temperatures may increase by 3 – 5 degrees C compared to pre-industrial levels by the end of the century and we have already reached 1 degree.”

Three to five degrees C of warming is utter disaster! 😱

SEA ICE AT BOTH POLES DECLINING

Paul Beckwith says Sea ice may be in that critical slowing down of phase-state before a collapse of sea ice. And for our southern listeners, there has been a huge fall in Antarctic sea ice. Just a few years ago it was still expanding.

LEAVING A BUFFER FOR NATURAL EMISSIONS

Apparently it is complicated to predict what level of C02 in the atmosphere would result in 5 degrees C warming. Many factors and feedbacks come into play, and there are some things we just don’t know.

After a recent paper, and my recent interview with lead author Tapio Schneider from NASA, we now know that somewhere starting around 1200 ppm, stratocumulus clouds cannot form to shade the Earth, adding ANOTHER 8 to 14 degrees C of warming.

That is definitely game over for humans and much of life. Humans of course will think at 800 ppm, they still have another 400 ppm margin before hitting that final brick wall. But that fails to realize that as the world warms, the contribution from natural processes increases as well, and most of that is irreversible. How much buffer do we need to leave for things like permafrost thawing or dying rainforests
 

Regarding that idea of needing to leave room for natural emissions, we have this from another Radio Ecoshock guest, Australian super-scientist Will Steffen, quote:

“Human emissions of greenhouse gas are not the sole determinant of temperature on Earth… Our study suggests that human-induced global warming of 2 degrees Celsius may trigger other Earth system processes, often called ‘feedbacks,’ that can drive further warming — even if we stop emitting greenhouse gases“.

That was from the blockbuster study published in PNAS August 14, 2018, titled “Trajectories of the Earth System in the Anthropocene”. I interviewed Will Steffen, and Paul blogged about it and did a You tube video on that.


Earth Climate System: Terrible Trajectories to Hothouse



THE PARIS CLIMATE ACCORD WILL NOT SAVE US


Again, that Trajectories study expected the average global temperature to settle between 4 and 5 degrees C hotter than pre-industrial, even if the Paris Climate Accords were carried out, which is not happening. Sea levels would go up 10 to 60 meters, which is 33 to 197 feet. That means even our best climate plan takes us to disaster not just for this civilization, but mass extinction. That’s our plan! We can do better.

In his You tube text for his video “Earth Climate System: Terrible Trajectories to Hothouse, Paul wrote:

Quote
“I fear that we have already gone over that cliff, and I declare a global climate change emergency to claw back up the rock face to attempt to regain system stability, or face an untenable calamity of biblical proportions.

A LOT OF EYES ON PAUL BECKWITH

Paul gets a lot of views for his blog at paulbeckwith.net. On You tube Paul currently has over 15,000 subscribers and 538 videos. As of April 11, his channel had 3,257,000 views. Beckwith tells how he became an electronic climate science teacher to the world. Perhaps Shackleton the cat 👍 is drawing extra views as well  ;D. Be sure and support Paul Beckwith’s work.

Arctic Feedbacks Stopping Winter Sea-Ice Refreezing: Part 1 of 2 // Apr 18, 2019


I discuss the very latest cutting edge scientific understanding on a powerful Arctic feedback that keeps regions of open, ice-free Arctic from refreezing during the dead of winter–December 1st to February 28th:

► Albedo feedbacks are NOT happening at this time since the Arctic is in total 24/7 darkness.

► What IS happening: turbulent heat flux (sensible + latent) plus increased upwelling long-wave radiation brings heat from the ocean up into the lowest 1.5 km of the atmosphere;

► More downwelling long-wave radiation prevents sea-ice formation.

This feedback increased 8.9% per year from 1979 to 2016.

Oops 😲. Arctic Emissions of Nitrous Oxide GHG a Dozen Times Worse Than Expected. Duh. Part 1 And 2



Paul Beckwith Climate Scientist

Published on Apr 20, 2019

Surprise... Nitrous oxide emissions from our rapidly warming north are up to 12-times higher than we previously thought, since thawing Arctic permafrost is a huge source.

The problem is:

1)the top 3 meters of permafrost contains 73 billion tons of nitrogen;

2)as it thaws microbial action releases bucket loads of N2O; and

3)N2O is a very powerful Greenhouse Gas, with a Global Warming Potential about 300 times that of CO2 (lifetime in atmosphere of 114 years). In my last video I chatted about what this all means; here I show the science in plots and images from the paper.

There is nothing like a family Easter trip to Toronto to get my creative rant juices flowing. I let loose about monsoon-like rainfall with spring snowmelt about to cause massive Quebec/Ontario flooding, the pathetic state of Canadian politicians of all ilks (Alberta NDP cheerleading tar sands/pipelines, recently replaced by climate denying morons of the newly elected United Conservative Party under Jason Kenney; Turdeau’s federal Liberal lunacy plan of buying pipelines to fund climate action, Doug Ford’s Ontario Conservative Party propaganda with gas station stickers, and Andrew Scheer’s federal Conservative climate nuttiness.

God help us with these Neanderthals at the helm. Abrupt climate change mayhem is exceeded only by even more abrupt political stupidity.
