I've watched many climate change presentations on KZbin and this is about the most comprehensive and scientific assessment of where we are and where we are going. As long as this stays up here, I'm going to refer back to see how the actuality compares to his science. This should be taught in schools. I'm not optimistic. The world population is 8 Billion and projected to keep going up to 10 Billion. These 2 Billion extra people are going to want what we have, before we even think about reducing what our 8 Billion already consume. I'm not sure inequality is the key economic factor. Rich or poor, we are all addicted to GROWTH. As long as this holds everyone seems to want to be richer tomorrow than today. Happy note : Stuart MacRae, composer, from my little country (Scotland) has composed an opera called ANTHROPOCENE, around a group of scientists that are trapped in the arctic ice. It has been performed by Scottish Opera!

Absolutely brilliant and speaks very much to my second book, The Circularity of Life: An Essential Shift for Sustainability. This book is about a paradigm shift, a shift in perception, where we need to see ourselves as part of the web of life as all beings and systems are interconnected and interdependent. In order for us to live sustainably on this planet, we need to sustain all life. In doing this we sustain ourselves. Sustainability then becomes reframed as the ability to sustain life. If we do not do that, then we are screwed. It also means that the role or purpose of the economy is to do that - money, profit with purpose.

[@Reason-n-Rhyme]

I am very conservative but agree with the entire presentation. The Paris accord is great but has no teeth and no guidance of how to do the super-painful work and force severe austerity of wealthy nations. World leaders are merely posing, doing little, bragging, and not taking the painful news home and delivering the real news that is political suicide. We are on a circus train; bridge ahead is out; driver is asleep; and the monkeys are running wild. Politicians do just enough to have a superficial eco accomplishment for their retirement vanity libraries. Nothing will get done until humanity begins to hurt badly unless we find super-leaders who have a plan. Each nation will wait for the other nations to do their duty. I’ve seen this mentality in business. Several times I fought to stop production of dangerous products and was told, “We want to stop production, but until our competitor stops, we won’t.” Sometimes the engineers had fixes ready but were prevented from acting. Sales never wanted to “rock the boat.” As a research engineer I was frequently frustrated. They paid me very well and praised me, but stopped me at nearly every turn. Science should make decisions or at least have an equal vote. When money men run the world; it is all about the short-term and their pride. The only other option is global war and one world government which no sane person wants. The science is easy and agreed upon relative to the people problems. I saw this disaster coming in college in 1969. We had a prototype electric car at OU which we drove around. And extremely little has been done in 54 years. Yes solar panels, wind, electric cars, and recycling are a start, but very late and only a tiny fraction of solution. At a minimum we are gorging ourselves on finite oil, gas, and coal; leaving nothing for future generations but a depleted, polluted, half-dead planet. But if America went green quickly it would become weak and ripe for conquest by its enemies. Plus going green is extremely divisive as energy exporting nations depend heavily on oil exports for their elite to survive in style. Friends and family tell me they won’t give up any of their lifestyle without a fight to the death. How do we educate them or force them to live on a fraction of their current energy consumption and goodies. The party is just about over. The health care industry, entitlements, national debts, vacations, fossil fuels, etc must decrease; yet they keep rising. The days of leaders playing Santa Claus are over. I’ve traveled the world for work. Third world people have told me, “Now it is our time to have cars and nice homes.” How do we deny them, after we’ve splurged so much for so long? Even if America and the Europe hit zero CO2, the third world would continue flooding the atmosphere and oceans. Some third world countries are still producing DDT, old Freon, and dumping rivers of trash into the oceans. It is not the fault of the masses but their bad leaders. Vital Needs: 1. Education & influencing to build a strong majority. Education has been superficial, spotty, and weak. We need debates among experts. Deniers need to be exposed for the false prophets they are. 2. Great ideas of how to cool the planet quickly. We could put up satellite mirrors to shade the earth. Or we could have airplane deposit soot in the stratosphere. But it would take monumental UN will and diplomacy to do that. 3. Great ideas of how to greatly reduce industry and toxic chemicals without crashing economies, or starting wars.

[@aaronbr2001]

[@mapfeu]

I am inclined to think that human civilizatuion (the to HAVE) is incompatible with the metabolism of natural life systems (the to BE). We may be able to figure out what is wrong with our human-centric approach to the Blue Planet. We are totally unable to pick up the challenge. If the human population could have been stabilized in the 1 billion we should be in a position to manage the antagonism between the humans and the Blue Planet under the most favorable circumstances and a super-high consciousness of how to act out without destroy the life support systems. This two IFs are a pipe-dream. It will not happen. My best guess is that all those tipping points will occur and terminate not only human life but practically all life on earth. And if nuclear weapons should play a role in war activities the fate of humans get very much dimmer in very short period of time. We are too much living with the moto: "anything goes - nothing matters". If that is true - WE ARE TOAST possibly much faster than anybody currently thinks... Ironically the total collapse of the financial casino may bear much more immanently on survival issues than the huge ecological challenges a little bit further out..... Paul F., Caracas, Basel

This is almost August 2022. All wars and arms production running full speed. I can't see one thing as yet decreasing global emissions. Even with wind and solar the CO2 production continues to rise. The ocean is warming, the coral reefs are almost dead, the ocean is losing it's capacity to absorb CO2, the Amazon forest is now a net emitter of greenhouse gasses. Now would someone tell me we are to turn the climate pollution back to 2020 now, and I mean today when there has yet to be any reduction as yet anywhere. My personal estimate is we are pretty much toast by 2040 with no return possible. Someone in a previous comment suggested WWIII and nuclear winter. That is the only solution that I have been able to come up with so far. There actually is a solution that could be done by combining Calcium and CO2 into Lime in the ocean. It would require about 450 large units worldwide placed in the oceans. Ha, not a chance as wars and arms production would have to be stopped. I'm too old to worry about it anymore, I'll be gone shortly.

[@Patatmetmayo]

There are doomers, and there are those of us who are called bloomers. Climate is always changing, as a result of a combination of many things we do not have control over as humans. Life will find a way to adapt and continue existing, as will we as humans. CO2 is way overrated, drop our emissions down to 0 today and CO2 levels in the atmosphere will still continue to rise for the coming 50-100 years or maybe longer. Look at the milankovitch cycles, which clearly shows that as global temperature goes up, it is followed by rising CO2 levels. Then global temperature goes down again later in the cycle, and 50-100 years after that CO2 levels top out and follows the way down with the temperature. CO2 is a lagging indicator, not a leading one. If we as humans want to do something we should focus on our methane emissions and stop deforestation. Lowering our CO2 emissions should not be top priority, as it will not change anything in the next 100 years. I think it's more likely we will have to increase our greenhouse gas emissions in the future to prevent global cooling, as 6 degrees of cooling would be way worse for our habitat than a few degrees of warming.

If you read Plows Plagues and Petroleum by Ruddiman, the Anthropocene started around 5 to 7000 years ago when man had a significant effect on the climate (slowed down our slide into the next glacial period). If you look at major extinctions, the Anthropocene started 50,000 years ago in Australia, 12,000 years ago in the Americas and 700 years ago in New Zealand. Arguably we have been at it long before the so called industrial revolution.

[@grindupBaker]

If the new huge 24k GMST proxy is more correct than the consensus of the old ones then the effect from 5 to 7000 years ago to 1850 is double what Bill shows at 1.2 of natural cooling held back (all of it) rather than the 0.6 of natural cooling held back (half of it) that Bill shows.

The early Anthropocene hypothesis is very logical when I look at the data. It depends on sensitivity of the earth system, but another piece is a brief global cooling after the depopulating of the americas and its subsequent rewilding through the 16-17th centuries.

The graphics are reflective of the unintended design consequences resulting from real politics, the blinded economics of maximum profiteering and minimum accountability for the ecology by which we live. The administrative process is necessarily dualistic, in which an Autocratic control of consensus has final say over the democratic governance framework, (we wish). It's a Tripartite idea cooperating with the military and paramilitary, if there's no Conformal Ideology dominating by force of arms and subservient Law. So if "power corrupts and absolute power corrupts absolutely" is the typical result of self-serving Ideology, then there's our problem with Military Industrial Complex masquerading as Defence and doing so by abuse of the Honour Systems, hiding nefarious fraudulent criminality behind the most human of human behaviours, service to your country, nation, district, and family. The terror of Nuclear Weapons is abused to extract fortunes from the public that they are supposed to protect, but a 50X planet kill ratio is obscenity defined. Money is without intrinsic value, so piles of it accumulated by fraudulent political dishonesty, are inverse wealth and indicate debt to the society it has been extracted from. This should stop, the actual Defenders who understand what Defence is intended for can carry out the trust in their fellowship Ideology they signed on to with the promise of their lives.

Arguing that tipping points happens in certain amounts of years, is not very good analogy. They are happening when they are, but the actual point cannot be seen before and most likely not evenduring the changing point. So all timescales should be scales, not singular years. (like in 27 mins in this video). So they should be presented something like: Arctic summer sea ice will go beyond permanent tipping losses in 0-40 years (so called blue ocean event needs only 1 greater storm that mixes ice on top with heat on below), WAIS in 0-50 years (ie. Thwaites glacier is currently changing rapidly), Amazon rainforest in 0-50 years (lost 2 raining patterns out from 7 already), Greenland ice sheet in 0-30 years (more and more scietists argue that this may have happened already, in some areas there have been 10 meter drops in a single year that means the future warming is going to melt it even faster, ~0,06C/10m change + melting season/daily melting is longer), ... Having a singular year in these random events is misleading for the people that have no scientific background. Therefore likely range of the events is better way to argue that these events may happen today or in next 40 years or so.

One issue that does not seem to get anyone's attention is how warming reduces our ability to take effective action to address changes that will translate into preventing runaway climate change. When climate disasters occur, resources are both lost due to destruction of the environments and lost in mad frenzies to handle the crises. We can't be concerned about how much fossil fuel is being conserved when air support for fires is needed for water dumping on the fires. We can't be worried about how much coal or diesel is being used to run generators in power plants that need to meet the demand of sky high air conditioning use during heat bubbles.

I'm going to solve the puzzle. For a large part of approximately the past 15 years, there was a manmade, intentionally formed and maintained capped inversion in the Millet Swale catchment area, southeast of Snowflake, Arizona. An inversion inhibits convection, traps heat and inhibits precipitation. The heat and lack of precipitation dries up the ground. The ground subsides, reducing aeration. The ground also develops a hard shell that inhibits infiltration of water. Heat that is trapped at the surface is stored in the ground, and since the ground can't breath as efficiently more heat will stay in the ground, and that heat will move along the underground temperature gradients. Millet Swale drains to Silver Creek, Little Colorado River, Colorado River, thru Grand Canyon and down to Lake Mead. As an analogy, one day you decide to rearrange the living room on the sunny side of the house and absent-mindedly place a chair in front of the cooling vent for the living room. The entire house heats up, because the cooling system is working less efficiently, due to the excess pressure at the blockage. Remove the chair, and the house cools down quickly. The drains (washes, rivers, lakes) also function as vents. Blocking one vent increases the pressure on all of the vents. More pressure means more heat, so now this inversion is drying up the rest of the Basin and beyond. There's the cause of duration and severity of the Southwest Drought. The ground couldn't breath, across the affected Southwest and beyond. The inversion was cooking the planet. With less water in the ground, carbon sequestration was inhibited around the globe. I have been fighting this inversion for ten years, but it was intentionally maintained. In early June of 2022, I permanently destroyed the inversion. All of these floods, heat waves, other severe weather and natural disasters are a result of the release of the excess heat that has been stored in the ground, now that so much pressure has been released. The chair has been removed from the vent. The planet is now cooling. Carbon dioxide levels will subside, now that the water can get from the ocean to the ground. Food security is safe. The tropics can return to habitabilty. However, an unnatural high pressure remains, because I don't have access to the private property. The high pressure is surrounded by lower pressure, which lowers the pressure of all of the vents, so now excess moisture is being draw from the lakes and oceans. Phoenix should prepare for the blizzards. I'm sure that you can link other consequences. Are we ready for a new Ice Age? The problems in Millet Swale go back even further. I believe the neighborhood was subdivided for private use back around 1970. Residents started building homes in a very sensitive area, at the top of the hill. The great grandchildren of Frank and Jesse James settled here, and I have heard some interesting history from one of the great, great grandsons, who used to live in my home and now lives three-quarters of a mile down the road from me. The James clan liked to collect junk. I heard a story that Jesse James IV, Frank James IV and the rest of the James clan collected so many junk cars that it took weeks to remove all of them. There is another junkyard that is approximately rwo miles from me-an actual junkyard. Another neighbor has a lot of junk cars that accumulated. Another neighbor who is half a mile to my east used to collect metal washing machines and other junk, to save for a rainy day, like a piggy bank. There are many previously abandoned properties with fallen buildings, and many of these buildings had metal roofs. When metal roofing panels and other abandoned junk lay on the ground in direct sunlight, they collect a lot of heat. As I mentioned earlier, the pressure that arises blocks the vents and heats up the ground. Also when the neighborhood was subdivided, leases were sold to cattlemen for Open Grazing. During the Southwest Drought and especially when the inversion was maintained, the cattle decimated the ground cover, which just increased the pressure. Navajo County should really do something about these abandoned properties. The neighborhood has become very attractive, so now more people are moving in. A few are putting more and more shipping containers and more heat collectors in direct sunlight. That's a lot of metal with a huge surface area, in direct sunlight, all day long. This neighborhood probably isn't the only neighborhood with these problems at the top of the mountain. Do you get the big picture? Everything can be verified in satellite photos and County records. Edits: Typos and corrected details that I misremembered. I forgot to proofread.

More ozone-destroying radioactive nuclides would be released into the atmosphere by a nuclear war, but many of the nuclear reactors would be destroyed by nuclear warheads. This would cause the vaporization of the nuclear reactor cores, which may drive much of the radioactive nuclides from the vaporized core ABOVE THE OZONE LAYER, resulting in less ozone layer destruction than if the reactor cores just meltdown at groundlevel.

What about before all your data? You are looking to recently?

The Anthropocene will more likely be considered an event by future geologists, not a geologic era or epoch. They want to start the Anthropocene in 1950. It might be over by 2050. Seeing how the Younger-Dryas, which lasted several hundred years has been called an event, I don't see how a human era lasting little more than a hundred years could be considered anything more than an event.

Thats because the fight between capitalism and communism through out the 20th centuary for global domination brought about the current free global trade system with captalism now on top, it's allowed population in poor countires and consumption in rich countries to explode, a bit of worst of both worlds if you ask me

[@coolworx]

11:58 I think this is wrong. When certain bacteria figured out photosynthesis, and then began "polluting" the atmosphere with free oxygen, it caused a mass extinction called the Great Oxidation Event.

There is some altered temperature data that is way off base in your graphs. Temperatures in the 1930s and 1950s were equally high as current conditions. The medieval warm period is also missing. There are numerous inaccuracies in this information. There is no threat to human existence. You’ll be heading over the cliff past the tipping point by yourself when the unaltered data is revealed.

[@oderbie]

Since you apparently believe that you know more than one of the leading climate scientists in the world perhaps you wouldn’t mind actually providing the data to back up your assertions. That’s what science is called

[@janebadon3988]

I think you’ll get a much better predictive model if you look back 100,000s of thousands years. From the data you show here, you can get the idea that temperatures are based on human activity, instead of the cycles of the sun, magnetic pole reversals and galactic sheet rotations. OUR FUTURE IS COLD! LOOK AT THE WHOLE PICTURE!

[@internationalwatergrid6825]

Is 300ppm the highest atmospheric CO2 has gone if the top layers of ice melted at higher ppm, leaving no tell-tale bubbles in the ice? If the ice cores date back 800,000 years, then it's clear that thick layers of ice remained in Antarctica all through the 7 known troughs and peaks of CO2, so do we have to wait for more melting before the next ice age starts? What causes the turning point from rise to fall in CO2, temperature, etc? I think we need to look at the 3 phases of water - solid, liquid gas - through each sub period to know where we are. Just thinking out loud. 🤔

[@kimfreeborn]

"During the 1,900 years before the 20th century, it is likely that the next warmest period was from 950 to 1100, with peaks at different times in different regions. This has been called the Medieval Warm Period, and some evidence suggests widespread cooler conditions during a period around the 17th century known as the Little Ice Age. In the "hockey stick controversy", climate change deniers have asserted that the Medieval Warm Period was warmer than at present, and have disputed the data and methods of climate reconstructions."

The good professor reveals his political - and, consequently, 'systems-dynamic' - naivete in alluding to the conflict in the Ukraine as some sort of 'little spat' (rather than as the logical result of the expansion of US empire to the borders of Russia). The whole point is that the United States - the most income unequal nation on earth - is also a world-destroying empire that will simply not stop, and not allow any move (or time) by the planet's other (more rational) nations to address the existential issue of the day....and all the days to come. By failing to call out the realities of the political system in which we in the West live, i.e., a brutal, rapacious, imperium - and the rest of the world either suffers or fights against - the scientific community is failing in its systems analysis of the situation. It's as though 'systems' to these scientists doesn't actually include, you know, realpolitik, i.e., the real political world in which we actually live. I wince when I hear and see this concerted and repeated aversion to the imperialist elephant in the room.

I must ask, Mr scientist. Is the air con in your office, the lighting, the power to run your video recorder, produced from carbon? Or do you have solar panels and batteries to run it all? Solar panels made from mined minerals, mined with diesel equipment, processed with coal or gas powered electricity? Please put on your science hat and show me how solar, wind and hydro can produce enough electricity to make your aluminum for the solar panels, and wind turbines. Show me how huge mining machinery can operate on battery power and what happens to those enormous batteries when they are depleted. Show me how the planet will every harvest enough energy from sun and wind to keep your air con running or charge a million E Vehicles. Are you personally prepared to go back to hunting and gathering because that is what it will take for humans to reverse the damage that we have done.
