    Enjoyed Rachel's Farm on bbc4 last night. It's about the conversion of farm land to re-generative farming- in a nutshell moving away from chemicals and boosting nature's processes (e.g. biodiversity) in sustainable systems.

    https://www.bbc.co.uk/iplayer/episode/m0027fw1/rachels-farm

    It's set in Australia and that backdrop helped to make several points which 'stuck' for me.

    1. The indigenous (aboriginal) people did practice sustainable farming (think we all know that anyway), but industrial processes striving for high yield means constant damage to soils and natural processes.  

    2. Australia has droughts and floods, which can further denude the soil of its richness. We get that here too now increasingly. One way round it was to create a moat on high ground to hold the water at a higher level so it permeated the soil below and around, keeping it at a more constant level of moisture. It's hard for farmers, especially on undulating land to cope with extremes of weather. And fire risks are also increasing in association with lengthy dry spells (as seen in London just a couple of years ago).

    3. Carbon dioxide is absorbed by trees and grasses, so really these things (trees, green foliage etc), come out of 'thin air' - we all knew this anyway right (surely?!) but they used a couple of great animations back this up.

    4. Soil is a rich complex universe of bugs and critters all doing their thing. The dung beetle is vital and where it doesn't flourish, the soil suffers greatly.

    5. Carbon trading relies on having certified sites, like Rachel's Farm where purchasers/ investors/ polluters can offset their carbon footprint, so enriching the nation's biodiversity while maintaining a course to net zero (I have no idea what Australia's climate policies are currently but it was re-assuring to see people like Rachel and her network doing their bit).  


    There was more but overall I thought it was good family viewing and well worth a watch and taught me those few things too.
    We must use 'nature based' solutions wherever we can, working with our natural environment, instead of against.

    I recommend books by Tony Juniper who is Chair of Natural England, I think you would enjoy them. I haven't read all his books, but 'What has Nature ever done for us' and 'What Nature does for Britain' are excellent and try to quantify in economic terms, the benefits, for all of us, of looking after nature.

    "WOKE GREEN MOB"

    A very apt description of the numerous posters who are Woke, Green, and behave like a Mob on this particular thread and numerous others in the past. 

    Who chose to throw abuse, insults and try to silence anyone who dares challenge their views in any way, and who, coincidentally, all happen to come from the same side of the political fence.
    Wasn’t going to post on this thread again but you’ve given a classic lesson in trolling here. Nothing to do with the subject and only written to gain a response and dig at others. Anyway. Now I’m out.

    Mismanaged climate disasters are bolstering far-right parties that channel public anger at political leaders while denying human-driven climate change. In Spain, the far-right Vox party gained traction after the October floods in Valencia, which killed over 220 people and exposed governmental shortcomings. The conservative regional government was criticised for failing to warn residents of flood risks, while the Socialist-led national government faced backlash for its slow response. Public anger overshadowed discussions on the role of climate change, which scientists link to record Mediterranean temperatures driving extreme rainfall. 

    Vox capitalised on these failures, promoting grassroots aid efforts and criticising the authorities. Its national support grew from 10.5% to 13.8% post-floods, despite controversial decisions like cancelling a proposed emergency unit and appointing a former bullfighter to a key cultural role. Spanish Transport Minister Óscar Puente highlighted the emotional nature of disaster reactions, which often neglect climate change’s underlying role.

    Historical parallels exist; far-right groups exploited Germany’s 2021 floods to spread misinformation. Puente stressed the need for long-term infrastructure adaptation and significant investment to address climate realities. Spain has allocated €16.6 billion for flood recovery, but widespread criticism persists, reflecting the challenges of managing disasters in a warming world.

    Also, I don't think @bobmunro would claim to be the first person to use the name Queerie. I think it may have been someone with a chip on his shoulder. 

    Vox is a far-right political party in Spain known for its nationalist, populist and conservative stances. It frequently criticises immigration policies, promotes traditional Spanish cultural values and opposes regional autonomy movements. The party is sceptical of man-made climate change, often questioning scientific consensus and downplaying its significance. Vox has resisted climate-focused policies, such as emergency preparedness initiatives and attributes environmental disasters more to governmental mismanagement than to climate change. This approach aligns with their broader agenda of challenging mainstream political narratives and capitalising on public discontent with traditional parties.

    I think you forgot "Quote from the Financial times" !

    Rather than trying to pretend that you get all this stuff from the top of your head 🤣
    To anyone that thought I was pretending I get all this stuff from the top of my head, I apologise.  (Except for Queerie, who seems to be the only one who imagines I made such a claim).  

    For everyone else, here's a link to the Financial Times. The article highlights the challenges of implementing climate policies amidst public discontent. Populist movements thrive on the perception that the poor bear the brunt of economic shifts. Decarbonisation requires massive societal changes, affecting low earners disproportionately. To succeed, governments must offer substantial support to vulnerable groups, avoiding further inequality-fueled backlash.

  • @swordfish I have just finished watching Rachel's Farm and what an uplifting watch it was. Thank you for recommending it.

    It was a lesson in how important biodiversity is to mitigating Climate Change. 

    I know that Kent Wildlife Trust were working with farmers to better manage the soil and prevent leaching into waterways. Hopefully more farmers will use regeneration methods  in the future.

    Interesting addition for everyone who cites cost as a reason not to try and reduce greenhouse emisions as it would put the bills up. Try and imagine the cost as we fry the planet!

    Could someone explain how the national grid can supply electricity to to one energy supplier who advertises on TV that their electricity  is from 100% renewable sources, when renewables cannot meet the demand do they turn off supplies to their customers?  It all comes down to same wires, so say I change my supplier how does  National Grid route rewneable only energy to my house and not to the house next door who supplier does not advertise that the source of their electricity is from 100% renewable. There is only one mains cable that connects all the 50 houses in my street.
    The National Grid operates like a giant pool or reservoir that all electricity producers (renewable or not) feed into. All consumers draw electricity from this same pool. Once electricity enters the grid, it is indistinguishable in terms of its source - whether it came from a wind turbine, a solar panel or a coal-fired power plant.
    When an energy supplier advertises that their electricity is from "100% renewable sources," they are not delivering separate renewable electrons directly to your house. Instead, they participate in a system called Renewable Energy Guarantees of Origin (REGOs). Here's how it works:
    • Renewable energy generators, like wind farms and solar plants, receive REGOs for the electricity they produce.
    • Suppliers can purchase these REGOs to match the amount of electricity they sell to their customers.
    • By buying enough REGOs to cover the electricity used by their customers, the supplier can claim that the electricity they supply is 100% renewable. 
    If renewable sources cannot meet total demand at a given time, the grid uses other sources (like gas or nuclear) to fill the gap. However, suppliers that claim to provide 100% renewable energy have already purchased sufficient REGOs to match their customers' usage over a year, even if the actual physical electricity at any moment includes contributions from non-renewable sources.
    Electricity doesn't flow in a way that allows separation by source to individual homes. It's not like a pipeline where you can direct specific water sources to specific taps. Instead, electrons flow through the grid based on demand and physical principles of electricity. The 100% renewable claim is about balancing the overall supply with purchases of renewable energy certificates, not about delivering a separate stream of green electricity to your home.
    Switching to a renewable supplier supports the broader transition to green energy because:
    1. It increases demand for renewable energy certificates like REGOs.
    2. This incentivises further investment in renewable generation.
    3. Over time, it contributes to a larger proportion of renewables in the grid.

    In summary, electricity from renewable sources and fossil fuels mixes in the grid. Suppliers offering "100% renewable" electricity ensure that, over time, their customers’ demand is matched by an equivalent amount of renewable generation. This system helps drive the growth of renewable energy on a national and global scale. 

    A simpler way to look at it is like this.  I buy organic milk from Tesco.  Tesco sells lots of milk, including organic.  The fact I buy organic milk doesn't stop Tesco from selling non-organic milk.  But if more and more customers of Tesco buy only organic milk, the total proportion of organic milk Tesco sells will increase.  Tesco is like the National Grid.  the producer of the organic milk I buy is the equivalent of the renewables energy supplier. 

    Thanks, just as I thought it misleading the consumers.  
    By that that reasoning, do you think that if you pay British Gas for your electricity, that they are sending you their own electrons directly to you, while your neighbour who's energy is supplied by EDF has a completely different set of electrons?

    I dont think its misleading. It's just the way it works and a small amount of research gives reasonable explanatio. 
    That is not what I am saying. When a suppler claims that it electricity come from 100% renewable sources why should I not believe that be the case, without having to do research on the Internet. I accept that Tesco's organic milk is what it says on the packing without going to the Internet to find out if it actually does.   
    What you are thinking they were claiming is impossible. You seem interested in the claim enough to form a negative opinion on it without looking any more into it, as if you were happy with your outcome regardless.

    Perhaps an energy supplier could be absolutely explicit on explaining it.  So is something like, "we only buy clean electricity" an accurate and obvious enough claim?  Would they still have to explain that you might not be getting the same electrons from a wind turbine?
  • According to the report ‘Business on the Edge: Building Industry Resilience to Climate Hazards’, the impact of climate change could drive fixed-asset losses of $560-610 billion per year across listed companies by 2035.

    Article 

    Summary:  The World Economic Forum's report, Business on the Edge: Building Industry Resilience to Climate Hazards, underscores the escalating risks climate change poses to businesses worldwide. Earth’s critical systems - such as ice sheets, ocean currents and permafrost - are nearing tipping points that could irreversibly disrupt ecosystems and economies. For example, the collapse of Greenland and West Antarctic ice sheets could trigger a sea-level rise of up to 10 meters, displacing millions and exacerbating food insecurity for over 500 million people. Similarly, weakening ocean circulation could destabilise weather patterns, intensify flooding and threaten vital economic hubs.

    These cascading risks are not theoretical. Businesses face a dual threat: physical damage to assets and operational disruptions from climate hazards like extreme heat, floods, and storms. The financial implications are severe, with projected global earnings losses of 6.6%–7.3% annually by 2035 if adaptive measures are not implemented. Sectors heavily dependent on natural resources, infrastructure, and global supply chains are particularly vulnerable.

    The report emphasises that building resilience is no longer optional. It provides a roadmap for businesses to mitigate risks by decarbonising operations, safeguarding natural systems and investing in climate adaptation strategies. These actions not only protect assets but also contribute to long-term sustainability, benefiting society and the planet. Collaboration between public and private sectors is highlighted as crucial for scaling solutions and managing shared risks.

    Inaction could have crippling consequences, as climate instability increases the likelihood of operational disruptions, resource scarcity, and systemic economic shocks. By integrating resilience planning into their strategies, businesses can safeguard their operations, maintain competitiveness, and support broader societal efforts to mitigate climate change’s impacts. The report urges leaders to act decisively, fostering innovative solutions to navigate an increasingly volatile world and secure a sustainable future. 

    Report 

    If you value the wealth created by big businesses, or if you fear increasing global migration, then protecting the climate and reversing the damage caused to the climate should be your number one priority, above all other things.  Sadly, it seems that, around the world, there are people who care desperately about the first two and are reticent to take appropriate action on the third.  Madness.

    3rd runway coming!

    Anyway back to freezing in my lounge to offset the emissions of 15,000 new aircraft
  • 3rd runway coming!

    Anyway back to freezing in my lounge to offset the emissions of 15,000 new aircraft
    Yes interesting to see how quickly it actually progresses. 

    Infrastructure investment is needed generally and not all can be fully green. Hopefully won’t get bogged down in red tape and we move on even if not universally liked. 
  • In a time when air travel should be reduced, expanding airport capacity is crazy. This will put back our net zero aspirations and the planet will suffer even more. Health will also suffer with the increased air pollution.

    Growth must not be achieved at the expense of the environment, 
    These decisions are not binary. 

    Compromise and balance always needed. 

    Airlines themselves are becoming more green we should remember too.

    Current Situation: Emissions from Connecting Flights
    Currently, many UK passengers flying long-haul must first take a short-haul flight to a European hub (e.g., Amsterdam Schiphol, Paris Charles de Gaulle, Frankfurt) before continuing their journey. These connecting flights introduce additional fuel consumption, emissions, and inefficiencies due to: 
    - Extra takeoff and landing cycles, which are fuel-intensive
    - Longer overall distances traveled, adding unnecessary CO₂ emissions
    - Potential layover delays, increasing aircraft ground operations and airport emissions
    A short-haul flight from Heathrow to Amsterdam (Schiphol) emits approximately 80-100 kg CO₂ per passenger (for a Boeing 737-800/A320).  
    A long-haul flight from Schiphol to New York (JFK) emits around 1.5-2.0 tonnes CO₂ per passenger on a Boeing 787 or A350.
    Adding those together:
    - With a connection (LHR → AMS → JFK):  100 kg CO₂ (LHR-AMS) + 1,800 kg CO₂ (AMS-JFK) = 1.9 tonnes CO₂ per passenger
    - With a direct Heathrow-JFK flight:  1.7 tonnes CO₂ per passenger  
    This suggests a potential saving of 200 kg CO₂ per passenger by avoiding the connection.

    Estimating GHG Savings from Heathrow’s Third Runway 
    Heathrow’s third runway is expected to allow an increase in direct long-haul routes, which should reduce the number of passengers transiting via European hubs. 
    Estimated Passenger Shift
    - The UK Department for Transport estimated that a third runway would add 260,000 additional flights per year (mostly long-haul).
    - If even 10 million passengers per year switch from indirect to direct flights, and each avoids 200 kg CO₂ per trip, that results in:
      10,000,000 x 200kg CO₂ = 2 million tonnes CO₂ saved annually 
    That’s a significant emissions saving, equivalent to taking nearly 1 million cars off the road (assuming ~2 tonnes CO₂ per car per year).

    Will Heathrow’s Third Runway Still Increase Overall Emissions?
    Even with these savings, it’s worth noting that a third runway increases total capacity, meaning:
    - More flights overall (including new short-haul feeder routes)
    - More aviation emissions, as total air traffic grows
    - Indirect emissions from airport expansion and increased ground transport

    However, compared to a scenario where Heathrow remains constrained and passengers continue flying via Europe, the third runway could be the lesser evil in terms of per-passenger emissions efficiency.
    - Increasing long-haul capacity at Heathrow could reduce per-passenger emissions by cutting unnecessary short-haul connections to European hubs. 
    - Potential savings: ~2 million tonnes CO₂ per year**, if enough passengers switch to direct long-haul routes.  
    - However, **total aviation emissions will still rise**, since more flights will operate overall.  

    If emissions reduction is the primary goal, Heathrow’s third runway alone isn’t the silver bullet, but it can contribute to a more efficient aviation network by reducing indirect flight emissions. As well as completing the third runway as soon as possible, the government should stipulate that its use is confined to the latest generations of fuel efficient aircraft (e.g. Boeing 787, Airbus A350) which are about 25% more fuel-efficient than older models. 
  • 3rd runway coming!

    Anyway back to freezing in my lounge to offset the emissions of 15,000 new aircraft
    Yes interesting to see how quickly it actually progresses. 

    Infrastructure investment is needed generally and not all can be fully green. Hopefully won’t get bogged down in red tape and we move on even if not universally liked. 
    A decade or two to go through the courts.

    Current Situation: Emissions from Connecting Flights
    Currently, many UK passengers flying long-haul must first take a short-haul flight to a European hub (e.g., Amsterdam Schiphol, Paris Charles de Gaulle, Frankfurt) before continuing their journey. These connecting flights introduce additional fuel consumption, emissions, and inefficiencies due to: 
    - Extra takeoff and landing cycles, which are fuel-intensive
    - Longer overall distances traveled, adding unnecessary CO₂ emissions
    - Potential layover delays, increasing aircraft ground operations and airport emissions
    A short-haul flight from Heathrow to Amsterdam (Schiphol) emits approximately 80-100 kg CO₂ per passenger (for a Boeing 737-800/A320).  
    A long-haul flight from Schiphol to New York (JFK) emits around 1.5-2.0 tonnes CO₂ per passenger on a Boeing 787 or A350.
    Adding those together:
    - With a connection (LHR → AMS → JFK):  100 kg CO₂ (LHR-AMS) + 1,800 kg CO₂ (AMS-JFK) = 1.9 tonnes CO₂ per passenger
    - With a direct Heathrow-JFK flight:  1.7 tonnes CO₂ per passenger  
    This suggests a potential saving of 200 kg CO₂ per passenger by avoiding the connection.

    Estimating GHG Savings from Heathrow’s Third Runway 
    Heathrow’s third runway is expected to allow an increase in direct long-haul routes, which should reduce the number of passengers transiting via European hubs. 
    Estimated Passenger Shift
    - The UK Department for Transport estimated that a third runway would add 260,000 additional flights per year (mostly long-haul).
    - If even 10 million passengers per year switch from indirect to direct flights, and each avoids 200 kg CO₂ per trip, that results in:
      10,000,000 x 200kg CO₂ = 2 million tonnes CO₂ saved annually 
    That’s a significant emissions saving, equivalent to taking nearly 1 million cars off the road (assuming ~2 tonnes CO₂ per car per year).

    Will Heathrow’s Third Runway Still Increase Overall Emissions?
    Even with these savings, it’s worth noting that a third runway increases total capacity, meaning:
    - More flights overall (including new short-haul feeder routes)

    It misses the point, instead of expanding air travel, it should be reduced.

  • If you fly KLM, Air France or Luthansa you'll still do those short haul flights. Doubt many use them to fly from Heathrow to the North America though. I thought the third runway's green benefits (lol!) was to help reduce the amount of planes circling around before landing?
