@@BiodiversityforaLivableClimate Regenerative agriculture is awesome. I work on a regenerative agriculture farm. It's too little too late. Improved knowledge of glacial-to-interglacial global temperature change implies that fast-feedback equilibrium climate sensitivity is at least ~4°C for doubled CO2 (2xCO2), with likely range 3.5-5.5°C. Greenhouse gas (GHG) climate forcing is 4.1 W/m2 larger in 2021 than in 1750, equivalent to 2xCO2 forcing. Global warming in the pipeline is greater than prior estimates. Eventual global warming due to today's GHG forcing alone -- after slow feedbacks operate -- is about 10°C. Human-made aerosols are a major climate forcing, mainly via their effect on clouds. We infer from paleoclimate data that aerosol cooling offset GHG warming for several millennia as civilization developed. A hinge-point in global warming occurred in 1970 as increased GHG warming outpaced aerosol cooling, leading to global warming of 0.18°C per decade. Aerosol cooling is larger than estimated in the current IPCC report, but it has declined since 2010 because of aerosol reductions in China and shipping. Without unprecedented global actions to reduce GHG growth, 2010 could be another hinge point, with global warming in following decades 50-100% greater than in the prior 40 years. The enormity of consequences of warming in the pipeline demands a new approach addressing legacy and future emissions. The essential requirement to "save" young people and future generations is return to Holocene-level global temperature. Three urgently required actions are: 1) a global increasing price on GHG emissions, 2) purposeful intervention to rapidly phase down present massive geoengineering of Earth's climate, and 3) renewed East-West cooperation in a way that accommodates developing world needs.

Another great lecture. Learning so much. Walter is up there with Christine Jones as my climate heroes from downunder. Bless you sir.

[@BiodiversityforaLivableClimate]

Walter and Christine have a lot of insight we could all use right now. Thank you for watching the presentation!

[@johnbaxter189]

Great report Walter, best climate report for years.

Your last finishing remark on heat dome's shielding the land from incoming low pressure systems is the most instantly gravitating point of the water cycle. it should I think be the appetizer as well as the entrée.

I have just seen an article about there being a shift of a 1meter circle at the North Pole, in other words the North Pole is decribing an arc of 1 meter. This, taking a line vertically through the axis of the planet and taking another line a right angle to the eguator would mean a signicant wobble at the Equator ------------ now we are pumping trillions of tonnes of undercround water to the surface, the largest aquifier on the planet under the Sahara is going to be, and is being mined by the nations domiciled there. In my opinion most of this water is going to evaporate to the atmosphere due to the methods of agriculture that it will be used to support .......... Climate Change aside this is contributing to a change in the balance of the Earth, I feel that the oceans will have to accomodate this inbalance by changing the fluid dynamics already in play............ which are already under stress from Polar Ice Caps Dissolution. Do you think that the Tipping Point could be closer that the six years I have heard mentioned?????????????

[@larrysiders1]

Adding to atmospheric humidity has negative feedback by creating more low clouds that reflect sunlight back into space (and triggers cooling rains)...as Jehne clearly describes here. All of the Climate Models assume that the increasing humidity (resulting from the minor CO2 warming) creates a 300% POSITIVE hydrological feedback (which hasn't occurred)...turning the insignificant CO2 warming into a theorized Climate Crisis. Factually, low cloud cover has steadily declined on the satellite records (~40 years)...just as Jehne describes here. And losing those clouds... accounts for ALL OF THE WARMING in the last 40 years...by incrrased direct solar heating of the earth's surface (land and oceans). Note that ocean waters never exceeds ~30°C because that warming ALWAYS TRIGGERS thunderstorms over the ocean in the tropics...leaving the top 2 meters of ocean water about 6° cooler than before the storms. Increased humidity there results in lots of cooling...NOT a 300% warming feedback. Only fixing Agriculture will cool the planet...as Jehne describes here. Reducing CO2 won't...because it isn't causing much of the warming...only ~0.7° C from CO2. Eliminating fossil fuels will impoverish the already poor everywhere (and destroy whole economies everywhere). Fixing Agriculture will enrich everyone...and our soils...and our food will have 10 X's more nutrition.

Have you worked with California gov. Or conservation groups to restore California water cycle to restore the crucial Sierra Nevada snow pack?

[@BiodiversityforaLivableClimate]

Not yet, but that certainly is something on our radar

[@johnbaxter189]

I'm been saying it's the water for years and years Defo need more green growth on the land. Ripping all the trees out for centuries is Wats put it in a mess. More water we store on the land the more green life we have which all stores the carbon, controls planetary temperature etc. I'm took hydrology to its max and realized the ice caps contain carbon and ice caps are water. I'm the man who claims to be able to dry the ocean up, or at least reduce them substantially. Basically we gotta take water out the oceans and store it on land more. We gotta break the weather cycle and not let all the fresh water return to the oceans. We need that much water storing on land it's unreal. I'm said a rapid emergency way to reduce the water levels is to get everyone on the planet to capture and trap as much water as possible in the land, using every means possible to trap the water. Dams and reservoirs will give us endless power. Too much water in the oceans right now bcuz we've killed so much plant life over the centuries, and killing plant life releases water. There's a simple balance between water on the land and water in the oceans. Tis very simple to fix it although it wud take every hand on earth to help and take hundreds of years but a most perfect balance can be found. To achieve wat Ur saying we wud have to get rid of the ice caps tho, but that wud create a lot more land for all. Lowering the oceans wud create more land and resources. Uve defo got the soil part right. Can't do all the maths myself but I know wat needs doing. Needs an effort like Pharoahs building pyramids not half hearted measures we using now. Building the sponge is the key.ur right. We need to get water out them oceans and on the land as fast as possible. We need billions and billions of trees and plants. Planets been so mismanaged it's unreal. At least we waking up now. Contact me for a talk. I can talk everything Ur talking and much much more. We can create a perfectly balanced climate and a paradise earth. Hydrology, that's the word I'm been looking for for years. All these idiots saying we gotta take carbon out the air are so so wrong. All about balance. Contact me and I'll tell u more. Thanks for listening. PS bible sez a man will come who can dry up the oceans and that man's me. Need billions to help me tho.

Passing this info to as many open minded farmers I can. Sent link to "the skate farm" they run a working farm here owner used to cook for a nice Amish restaurant. If we can achieve co neutral grid in 5 yr along with Elon Musk boring company long term plan for uncogesting City's main thoroughfares we can live the "Eden" where animals don't fear people. I see your work on that level. My squirrel "wally" has followed me for 30 ys. When ever I move just set out some bird seed and call him. Always looks a little dif. Brown or gray he runs treetops to roofs 1 block away. Lol. Sir Thank you for your diligence. As of the University's try to claim your theories using computer graphics and whatnot. PS since the fires I bought an 800 lb of bird food I have two one-gallon bird feeders it really adds up the birds here sound like car alarms we have five acres of trees. Peace take care of all always do well. Mike better known as frettiyeti if you need a KZbin chuckle some vid have well over 3000 edits such as "wavy Tues" traditional dance from India.

Hey check out thunderfoot 's videos on elon musk. Might help to see the flaws in the boring company. I hope this helped

The first thing you can do is to look at the sponge.

Too many people, houses, & buildings. True, it's the correct way to allow animals to grow but we eat too much meat - thus factory farming. :(

[@btudrus]

@@30stmFantasy Nonsense. We eat too little meat. We should stop eating the plants at all and eat only meat, because that's how we evolved. Meat is best for our health and best for the climate!
