- Climate Emergency Forum discusses the critical issue of deforestation, efforts to protect and restore forests globally and how forest loss contributes significantly to climate change.
This video was recorded on May 29th, 2024, and published on June 30th, 2024 and represents the opinions of the discussion participants.
The participants highlighted the alarming rate of forest loss, with approximately 10 football fields of tropical forest being cleared every minute. They emphasized that deforestation is primarily driven by agriculture, particularly cattle ranching and soy production for animal feed.
The conversation explored various strategies to combat deforestation and promote reforestation. Participants discussed the importance of sustainable agricultural practices, reducing meat consumption, and implementing stricter policies to protect forests. The group emphasized the need for a multifaceted approach involving governments, businesses, and local communities to address the complex issue of deforestation.
The dialogue also touched on the vital role forests play in biodiversity, carbon storage, and human well-being. Participants stressed the importance of preserving old-growth forests and the need to consider both immediate and long-term impacts of forest management decisions. They discussed how climate change is affecting forests through increased risks of wildfires, pests, and diseases. The group concluded by emphasizing the urgent need for global cooperation and action to protect and restore the world's forests for the benefit of both current and future generations.

Permaculture Practices & Soil Regenerative Practices have changed my whole yard landscape. I now have an "Oasis" in the middle of a sea of asphalt & concrete. I'm the only one who doesn't spend hours weeding, spraying, hiring landscapers and paying for "green recycling".
Thank you brother
Keep up the good work 🙏
Hello everyone, good morning from Brazil. I strolled this morning with my dog Bellina (unfortunately my other dog Mortadela passed away last week) and I noticed the iconic Brazilian Ipê trees are not blooming at all (you can check this tree if you google), because this winter has been way too warm. Millions of ipês across the country, not just in Rio de Janeiro, but also in Minas Gerais, São Paulo, and other states, didn't blossom. The dark green canopies of the forests that embrace the hills and mountains of Southeast Brazil should be aglow in tinges of pink, purple, and yellow. Not all of us have noticed, but it was in the news this morning. With a bit of sadness, I have to admit that my world is gone. I can only resuscitate the beauty of a winter morning stroll in my memory now. I wish it were solely for my missing dog...
We are not at the ipê flowering season yet. Those species should bloom in August/September.
That is so sad.
So sorry for the loss of your beloved companion.
Sorry, for the loss of your friend, I too lost my best friend a while back, all we can do, is get another.
you all are so great .
Thank you so much for your support.
Thanks guys for your videos on such an important topic.
Thank you so much for your support.
The benign intentions of this podcast are admirable and abundantly clear. I salute your efforts. However discussions about the well-being of FUTURE generations seem almost naively ludicrous. A quick perusal of the global situation from Ukraine to Gaza to sub-Saharan Africa and numerous other places should be sufficient evidence that the prevailing global power structure doesn't give a good damn about "future generations". Power and Wealth NOW is the prevailing zeitgeist that is propelling humanity in very problematic directions. Until - and unless, the human species can get control of its own exceptionalist mind-set, the rest of the Earth (the "natural world") will continue to deteriorate AROUND us and WITH us. Hopium only helps us to feel better about ourselves, but it does not - it cannot - it will not - address the fundamental problem : the power and control of Earth's future is in the hands of mad men.
nicely said
Well said!
@treefrog3349 Thank you the valuable comment.
I know it isn't easy but perhaps trying to find one reason to be hopeful in each of your videos might be a fun idea among all the doom and gloom. I echo Peter's anger and grief at the loss of our beautiful English countryside. Recently I have discovered a small patch of woodland on a private estate that used to be farmland, which we are allowed to walk freely on. The previous owners must have had some kind of conservation vision as they planted numerous different tree species along a stretch, and now many of them are of a good height. The biodiversity in this small area of mixed woodland, fallow fields and hedges is amazing in my eyes, albeit I have yet to discover a rare species. Even so, it is a pure joy to be able to walk from my home to this place and just be lost in Nature. Meanwhile the rainforests, with their thousand upon thousands of species, continue to fall to the banshee wail of the chainsaws.....
Such an important subject! Nature and trees must never become ‘scenery’ or another cash crop
I agree with everything you have said. Thank you for helping us understand. Keep going, we need you!
Thanks for the poetry Peter ❤
One of the revelations that came to me as a person raised close to the land, living near and within forests my entire life is the fact that most people in North America and Europe have little to no experience of nature aside from media or the occasional camping trip. People want and even crave nature but this culture marginalizes natural experience as recreation. This is tragic!
Contractors,builders, investors etc… are a different breed.
Theres a disease affecting the beech trees in our area (south west germany). At first glance they look healthy, only if you look at the very top you see dead branches. It always starts from the top. Nearly every beech is affected. It's so scary bc you know in a couple of years big portions of these forests will just be gone.
Its elm disease and ash die back where i am , awful .
we had a very significant drought last year that killed a bunch of native trees; the trees are still mostly standing but now it's clear that most of them are dying or are already dead and every windstorm knocks down dozens of them
Wonderful and insightful presentation. Thank you.
Permaculture needs to be pushed onto the agricultural community in the coming years. These large scale corporation’s that are pushing these giant Monocrop farms are destroying more than a a farms ecosystem it has a trickle down effect. They cause long last effects on towns around these farms.
God bless you hsve a nice sunday bye, bye. See you one day ....
Thank you, wonderful job!
You're welcome
Thanks here especially to Peter. His grounded reality, expertise and truth telling are not to be dismissed lightly. He says the world he knew in childhood is gone forever. I agree entirely as someone of roughly the same generation in my 70s. For a person born in the 1970s onwards they cannot ever experience the abundance of nature before their birth.
We also know the end of WW2 was the birth of the US century and hard right neoliberal economics of externality, profit and knowing the price of everything but the value of nothing. It was during this period that the economic foundations of hard right neoliberalism combined with capitalism was put on steroids via the corruption of our parliaments and increasingly corporate friendly law.
It's during the period post 1990 that we have more than doubled human burning of fossil fuels. During this period that more and more wars and coups were started by the West with vast uncounted emissions of greenhouse gases and war on societies in the global south, now turned to war at home via military police and ever increasing authoritarianism.
Unless we stop these trends now we are unlikely to see a global average temperature below 1.5º C to 2.5º C this century. In reality we are now at the point of trying to save society as we know it on a global scale. As Peter so rightly says the focus must be CO2 (or CO2 (e)) the most important thing of all right now. Thanks as always to the valuable and informative discussion by the team at Climate Emergency Forum Paul, Peter, Regina and Charles. We need a call to action!
Hello Regina,Paul and Peter..like has been described here before Houston saw a bad Dericho that did lots of damage to power lines and to skyscrapers downtown..lots of broken windows..And folks had no air conditioning for weeks after this happened because of the damage.Regina..maybe a good topic is Heat domes which you guys have covered before but seem to be getting bigger and covering more territory and states especially this summer..And also how they don't go away they just move along the jet stream and on the winds to other parts of the world..Case in point...The Heatdome bringing unheard-of Heat to Mexico City and South America then moving northward to plague the US this summer with unusual 1 month early Heat to the south,midwest,and even the east coast. Unfortunately it's time for an update..Thank you everyone for all that you are doing to bringing these topics to the public!!
I was hoping to learn more about the following question re: forests - With ever higher temperatures and climate deregulation, how big is the chance of trees planted today to even grow enough to replace cut down forests?
Liked Peter's Poem, here is a thought for you, through your programs many facts all true are presented and we thank you for all that work, but that mostly just reaches the mind, but in order to enact change what has to be reached is the heart, and I put it to you that a well thought out and heart felt poem has greater chance of doing that, than all the facts in the world.
Thanks for that
I had a dream about Paul Beckwith a few nights ago attending a meeting of a few people in a room of a university, then it was in a room with hundreds. The numbers subsided when Janice Faimengo of Queens University came in and asked if any one was here about the water with half the people leaving. Strange dream.
Regarding agricultural efficiency, I live in an area of Southwestern Ontario where increases in agricultural efficiency have resulted in a Jevon's paradox. Commodity prices are directly proportional to deforestation rates resulting in a Gold Rush mentality.
excellent discussion, great poem. awesome topic
Thanks for listening
I hope I haven' t said this before?😮😅 But I have altered my sisters garden to be wildlife friendly. The lawn, which is small, has just been turned into a flower meadow. The flower borders are full of herbacios perennials!😊 Her empty pond has been filled with plants, and I have introduced a native species of stickle back. But after doing this over a period of three years, there are very few invertebrates😮😢 Not that long ago, perhaps a decade? There used to be swarms of bees, hover flies, etc!!! I think our lovely scientists and farmers and people that garden in the old fashioned way, that is, kill everything that crawls or flies!!! I personally don't use any chemicals, what so ever!!!❤😊
The incompatibility of forest felling, fossil fuel emissions and a technological machine future with a healthy sane future ecological society influenced my career path 25+ years ago away from selling my engineering skills to businesses and governments to continue exploiting and pillaging the beauty of Life on Earth. Others need to find the courage to do the same if they are sincere.
Budgeting carbon emissions is accepting the path of the carbon emitters, the path of the bureacrat, the path of the controller, the path of those who surreptitiously enclose that commons. The budget and limit that needs to be heeded with immediate priority is the entropy budget and limit of Earth.
Carbon is important and factors into entropy but if entropy production by Earth starts to decline, this means the state of the Earth biosphere will reach a higher entropic state that is incompatible for the majority of current lifeforms to survive.
I guess I’d like to see covered information on aerosol masking effect and how if we reduce carbon emissions we reduce that effect and the planet warms even faster?
Or something about nuclear facilities meltdown if they’re not being cooled enough?
Don't forget about the grasslands.
Grasslands are just as important for capturing carbon, and providing food for animals plus humans.
There are tons of grasslands around the world you can't say the same about forests
Why is it soooo difficult for humans to understand the the carbon rise in the atmosphere is due to an emissions - sink imbalance.
In the absence of external carbon inputs, the biosphere will balance.
A forest will emit as much carbon as it sequesters. in other words, A forest will sequester as much carbon as it emits.
The use of fossil fuels is an external input, without an equivalent increase in biomass carbon, all the extra carbon goes into the air and water.
Deforestation is DECREASING Biomass. The lost biomass results in even more carbon in the atmosphere and water.
You're saying that canopies are shrinking, but what I'm finding in my surroundings is that, due to carbon fertilisation (CO2 ppm being 422 in June'24) the plant growth is speedy @2-3 times, their leaves are broadening in size, in narrow live plants the leaves of gramminie family are sharp & elongated. Flowering are more & all these are happening in an ecology, where there is severe moisture stress in soil. I dug & found roots are more elongated towards down only, lateral spreading is less. But in spite of good plant growth & flowering fruit setting is less @ 15-40% (varies depending on spp.). The fruits are small in size, as moisture stress is high and none is able to recognise it. All vegetation growth of each plant is almost vertical. Lateral spreading of branches, generally found in broadleaf plants are less or absent. Only due to massive deforestation the leaf area index (LAI) is reducing from 5/6 to 1.5/2 (Area of leaf in sq.mt on per sq.mt area). So, you can tell that the total canopy canopy is reducing, but all plant spp. are trying their best to thrive. In case of non-sessile lives, they are either changing their place (parrots from the south have nested in Britain), or are at the brink of extinction (Common crow & Raven, even Jackal, fox, street dogs & cats), which didn’t shift northward & are few in number.
This must be included in your next video.
Your comment is all nonsense
It was E. O. Wilson that deduced the biodiversity of an island is equal to the 4th power of it's area.
That function can be applied to other habitats as well as islands.
Reduce the area by a half and you have an understanding of not how much we fail to comprehend logarithmic functions but also the converse.
Tackling extractivism is a vital component to kick starting the circular economy and conserving habitat. By extractivism I also mean the roads and infrastructure that go with them and agriculture which should be considered as a form of extractivism.
The subject of soil and plant roots particularly perennial plant roots that can sequester and hold both more carbon and methane with its living microbiome of bacteria and microbes and this is why such plants can regenerate themselves back to life every year when the weather warms up! And is it not the earth's carbon cycle (between the atmosphere and in the ground) will be kept more in balance when the land/plants are stewarded/managed rather than just extracted!!!
What kind of impact will geoengineering have on saving the forest carbon sink?
"Saving"...?
The problem is, if nature if not seen as a market commodity, it is going to go.
About 5:30 in and it reminded me of precontract California. How many thousands of years did they live a sustainable life? We have lived in a sustainable manor much longer than we have not. Was it agriculture that started our unsustainable life styles?
But everything is moot until ghg emissions stop which there not . I have a lovely permaculture oasis but its not going to survive what's coming . Its a cool what could have been and its great if others do it but its still rearranging deck chairs on the titanic. Oasis are not enough without safe connecting corridors also . Even with 35 years of me doing this diversity is dropping , less butterflies , birds , frogs..everything .
Its amazing this is the only channel pointing this out .
Yes
Well.... At least we know.
I wonder why we don't grow more bamboo in regions which have the habitat to support it. Hardwood trees take decades/centuries to reach appreciable sizes whereas bamboo is almost a cut and come again source.
All bamboo has excellent potential for charcoal & biochar production & utilizing it as an alternative would allow the preservation of more traditional forests, which would still be felled to satisfy construction & furniture needs.
Doubtless the 400% growth in the human population over the past hundred years, & the associated resource requirements, is a significant driver in forest depletion.
The effect these videos have on the people in the comments section is terrifying.
Warer is a problem. Só tske only a shower per week. But majority if people Walter water for Notting ..
Tragically and despicably our species is hellbent on continuing on its rape and pillage of not only humanity but anything and everything else. Greed and bloodlust prevails.

hi regina, maybe we need to look for the leader of the future. not the father of our country, but of course! the mama?
Topic for you. Overshoot, Ecological Overshoot. Climate change is symptom of overshoot so it only makes sense to address this subject. Serves no purpose to try and fix a symptom without addressing the root causation. It really bothers me that this fact is so over looked.
What you all are saying is what indigenous peoples have been saying for centuries.
I live in India and heat and humidity is literally unbearable these However because my country is not developed people are still not worried about climate change.They prefer discussions about marriage kids and politics.
FIRE MITIGATION
I couldnt save my forest canopy from machine cowboys clearing huge strips through forrests.
RFS treated the 2020 Australian fires like a normal fire.
Usual local fires often start under the canopy and get up into the trees from bushes. Fire breaks have been used for a long time.
But in 2020 the heat and embers came from above the canopy.
In fire fighting they use the fire triangle to fight fire. By reducing one or more of these elements being Heat, fuel and oxygen.
They didnt care about biodiversity, only reducing fule by clearing huge fire breacks and bush. But they effectively increased temperature (heat) and lowered humidity with there mineral earth fire breaks. Removing bushes especially at the edges of canopies prevents micro climates thus reducing relative humidity even further.
Another factor is the convection currents, for example my road runs up hill. So as it heats up from the sun the air moves up hill. This increases airflow (oxygen to feed a fire), increases temperature and reduces humidity. Even worse with out bushes this heat can easily flow under the remaining canopy. This in my opinion drys out and stresses the trees much faster in these global heating events. Thus less dry heat will be required on drought stricken forests to have the same effect in the future.
In addition to this as these mineral earth fire breaks are not maintained weeds grow my concern is that they could ignight easyer, burn faster and hotter than bushes and trees under this type of ember atack.
Also the stress of the dought and then fires, and more holes in the conopy from fire mitigation was too much for my forest. Certain species of trees died leaving further holes in the forest canopy that long grass grew some in very hard to get to places.
On my property the black wattles were being eaten from somthing boring into the wood that the missing birds used to control. The stringybarks just died a slow death. Some did resprout but the new shoots died repeatedly untill the trees finally died. Some of these trees weren't even exposed directly to the fire.
In Australia Every utility carves there own path through the canopies in the bush. Roads, power, phone lines etc.

If you are truly open to suggestion, I am interested in the effect of the changing climate beneath the Earth surface. Obviously, continual deep mining, as well as shallow mining, has disturbed the balance of interweaving forces that have kept the Earth chugging along as it has for the time humanity and the Great Ape family have been on the Earth. The removal of oil and gas, I'm sure, as well as the injection of water, has an effect on that subterranean climate, as it is going to affect the density of the sub-strata. Even if, as some say, the substrata that they are mining has the density of concrete, concrete filled with oil is not going to have quite the same temperature or other characteristics as concrete exposed to air continuously or water. If there are tipping points in the various systems that are identified above surface, what are they below? Apparently in just the last couple decades, new effects and affects have been identified. Did they foresee these atmospheric rivers caused by the inability of rain to form in certain areas due to change in atmospheric make-up back in the '60s or even '90s? What might be lurking beneath the surface in terms of the upsetting of the intricate balance of forces affecting the Earth--for we know there are a multitude of interweaving forces/systems that involve inside/outside of this ball in space, as well as the "Heavenly bodies" that shine and pull upon it, and perhaps also exchange in subtle ways the make-up of the extended atmosphere? (Not a scientist here--just have some sources that do think deeply about this, and I find what they say quite logical and sensible.)
p.s. My sources also have great practical predictive ability. A year ago they told me eastern North Dakota, USA, where I live, would in the future have a milder winter and have more rain in the growing season. Boy, were they right on target this year! Never would have imagined a winter without snow in North Dakota or this continual rain, that has given me the best garden I've ever had so far. We'll see if this is a definite trend, but they sure called it. They also called it for the south USA, which so far is following the pattern that was explained to me.
I was also told a year ago that the Antarctic ice had a problem due to what was going on under the ice, almost like there was a layer collected under it that was causing an effect that was related to both CO2 in water and ocean subsurface interface, and so I've been watching the daily reports on the U.Maine Climate Reanalyzer, and once again they called it right. According to what I am told, the effect on the ice is like what we see when ice around here melts, it doesn't just melt from the perimeter, it gets pockmarked, kinda, and there is thinning of ice, etc. Even little pools of water forming on the ice. This is continuing. I noticed just a few days ago this new study that says exactly that, so apparently some groups are keying into it. The low ice formation last winter in Antarctica allowed the release of more CO2, if I understand this correctly, that was locked somehow there. I think this is what was said, that this helped create the atmospheric rivers. So it is all tied together. I was also told the AMOC has already tipped, it is beyond the point of recovery, although observations of course will drag. The tip of one system within a system, such as the AMOC, affects all the others. This also will change the traditional reliance on La Nina and El Nino, since these systems are entangled.
Uou know, I thonk we are going to have a harricane into Amazon area
We could talk about the possibility of building a global digital platform that can have conversations with millions of people around the world at the same time, to support a global collective democracy that is based on the principles of the Universal Declaration of Human Rights and the Earth Charter.
Since you're open to suggestions: Why not explore the difference between using pre-industrial temperatures for a baseline, and pre-humanity. I would assume that agriculture and livestock domestication for tens of thousands of years would have some affect on climate. But then again, our numbers were much smaller then. Thanks for the video, guys!
The AI people say AI will solve climate. I call Bulls..t. We need to challenge them to produce a plan. I would put up a grand for a benchmark test.
Just tell it like it is. You don't have to sugar coat it with hopium.
The growing climate crisis just said on CNN. It will be a growing crisis, alrighty.
Compare satellite images from 50 years ago with a recent ones, there's nearly 25% MORE GREEN NOW!
Damn people 🙄
