Have we been underestimating emissions from deforestation? Perhaps by as much as 100%?

In a world where we are worried about global warming and carbon emissions, it is insanity that we are still cutting down trees. Recent research shows it even more insane – the carbon footprint of deforestation has been shown to have doubled in the last 2 decades.

Unfortunately, this problem is for simple reasons. Generalizing, the majority of people who are worried about global warming are in developed countries – few of these countries have an significant rainforest left, as they cut them down (often centuries ago).

In developing countries, people are less worried about global warming. Are the stupid? No, of course not. In the developed world, for the vast majority of people, we do not need to worry about where our next meal is coming from (sure there are varying levels of poverty, but on the whole dying from starvation in the west is rare). In developing countries, however, starvation is still a problem that occurs from time to time. Terrible famines have occurred within living memory, which means that the populations in these countries are more concerned with plans to stay alive, not with concerns over how difficult they are making their descendants lives.

The worlds forests contain more than a century of human carbon emissions (from fossil fuels). In other words, if we cut it all down we will blow past all possible safety points and will be well in to runaway global warming. We need to help the countries which still contain rainforest – even one off payments in the billions are not enough. The west needs to assist countries with large rainforests, particularly the Democratic republic of the Congo, Indonesia, and Brazil in growing both their economies and food production in the smallest amount of space possible, alongside significant regular payments for retaining their rainforests.

Unfortunately, this is unlikely to happen. There is also significant differences between concern from individuals on the ground and the government. If this site succeeds we will create a marketplace for those living by rainforest to benefit, however if the government decides to cut down the forest this will not matter.

What is clear is that not only do we need to end deforestation, but we need to reverse deforestation in many places. This is not only necessary for global warming, but also for rainfall and the whole host of other reasons that benefit local people.

Federal resources minister of Australia declares that solar panels dont work in the dark

Australia seems to have a group of politicians that are totally anti renewable. Australia is perfectly situated to use renewable resources for all their power. When Keith Pitt was asked if he still believed renewables didn’t work – he gave this ridiculous statement. The junior partner in the government is demanding they work towards zero carbon by 2050.

The worlds largest solar farm is being built in Australia but to send the power to Singapore, perhaps this huge project will wake up the Australian citizenry to the idiocy of their government

The UK has 11 billion climate fund:60 ngo are calling for some of it to be used for family planning

Across much of the world where species are at risk of extinction there is an exploding human population. From Africa with rapidly growing populations in the east west and south, to Asia with growing populations in almost all countries, the biggest threat to the continued survival of wild species is the loss of habitat.

The thing is, that a rapidly growing population is generally an issue in countries which are poor. The reason for this is that they have lower standards of healthcare, and therefore less family planning.

As such, if the government were to set up a project which spend a couple of million educating educators in 50 countries across the third world, and supported the resulting work, the growth of the populations in these countries could slow or even stop and go into reverse. This would allow the standard of living to increase again.

Alongside these benefits, would be lower pressures on the wealth of biodiversity which so much of these countries economy is based around.

Importantly, this would be likely to have far more impact than it would cost.

Green projects in the UK are being endangered because of unfair transmission pricing

Transmission charges are paid when transporting electricity from where it is made to where it is used.

This is quite normal, and it is the way that the power grid has worked for centuries. This will become ever more important, as the distance between generation and consumption of electricity increases.

Why is this distance increasing? When you build a coal or gas powered power station, it does not need anything in particular to be able to make power. So long as it has a ready supply of what ever it uses to power its generators, electricity continues to flow.

Renewables are different. Wind turbines need to be erected in places where there is a lot of wind – this is why the UK has built so many off the coast. Solar power is generally either placed on large roofs (factories and such) or out in fields. We need to have more roofs filled and fewer fields – It would be possible to power all the UK power needs if all rooftops were covered, but that is a different subject). Fields are generally expensive near cities and cheap far away.

This is where the problem arises. The UK is capable of generating more than enough power for the British population. However, if electricity generated in Netherlands France and Germany are all let off transmission charges – as they currently are, but our own power generation has to pay it, this is the equivalent of giving all foreign electricity a significant discount. This is obviously insane, as it means that we discourage our own power generation, at a time where we should be investing billions in green power generation.

Analysis shows that on average EU power firms pay 48p per megawatt hour in the transmission system. In Scotland the average is £6.42 – more than 13 times the price. In the windiest parts of Scotland it is £736 per MWH

OFGEM needs to bring in rules that encourage the UK net zero target. This must happen fast. Without, we are likely to end up not building the tens of thousands of wind turbines necessary as it will cost more to export than it is worth.

Right now, we are essentially subsidizing imports and heavily taxing domestic power. This is a quick way for the government to kill off this entire industry.

Easyjet continues to make progress towards its zero carbon planes due in the sky 2030

One of the most complex issues to address in decarbonization is that of air travel. It is all very well for people to suggest that simply nobody should travel. This is not a long-term solution, not least because the vast majority of conservation relies on tourism to raise the funds for it to take place.

Long-haul flight is a problem to be fixed in the future, however easyjet is working on finding a solution to short haul flight of up to 500km.

Wright electric, the company which is developing the planes has announced that it has created an electric propulsion motor at 2MW. The aim would be to use 10 of these motors – which would add up to a similar amount of power as the aircraft the fly today. 2MW for an hour at full capacity would be 20MWH

Whether Wright electric has identified batteries that can supply enough power to run these motors for long is not yet known.

Montpelier a city in France realized its error, and dropped an order for 51 hydrogen buses for electric instead

Montpelier had set aside $33 million for this project, over 2 years. This decision was made, after local officials realized that electric buses would be 6 times cheaper to run. This price included the building of a plant to make the hydrogen.

In terms of cost, it was estimated that the buses (for which the council was given help buying but not for running costs) would cost 3 million euros to run, yet only 500,000 for electric. The per mile price was 0.15 euro instead of 0.95.

Although they were going to be helped in purchasing, the hydrogen buses are also between 150000-200000 euros more to buy in the first place.

The myriad reasons that hydrogen is not a good idea have been obvious for some time. Green hydrogen (much of hydrogen is taken out of gas- obviously a nonstarter if your aim is reducing carbon emissions) requires a great deal of electricity to split water, and it would be far more efficient to just put that electricity in batteries and use them. Another issue is the compression of the gas. The only possible place where hydrogen might be useful is in aeroplanes.

Apparently Low-carbon ambitions must not interfere with ‘normal life’

According to Xi Jinping, low-carbon ambitions must not interfere with modern day life! If this is true, then we are unlikely to get the cuts that we need.

Now, it is not unreasonable for a country to want to raise its standard of living. However, China is likely to be hit very hard by climate change. While you do not think of China as a low lying country like Bangladesh, 67,000 square km (about 26,000 square miles) lie 1m or less above sea level – and 67 million people live in this area. It is true that this only accounts for about 5% of Chinas population but given how crowded this country already is, this is likely to cause a lot of issues. More to the point Shanghai is only between 3m and 5m above sea level,

Around the world about 600 million people live close to the sea. Of course we understand that each country must look after its own citizens – but that includes protecting them from global warming. China currently accounts for 26% of global emissions, and the rest of the world cannot cut enough to make their emissions irrelevant.

Now, it is entirely true that the president may be trying to keep his own population on side, but we need the whole world to work on this problem. China accounts for 15% of the worlds GDP, then can not take a back seat.

In 2020, for the first time the UK got more energy from renewable sources than from fossil fuels

In 2020, renewable electricity accounted for 43% of the UK electricity, while fossil fuels accounted for just 38%. The remaining generation came from nuclear. Unfortunately, that proportion was reversed in 2021.

Never-the-less the British prime minister announced in October at the Conservative conference, that the aim is to reach 100% renewable electricity by 2035 (I would suggest that they need to decide if nuclear is a green generation or not – I would suggest it is, but it should therefore be included in the figures, in the long-term it is not likely to be needed, we should be able to generate all our electricity from solar and wind).

It is encouraging to think that by 2035 all our electricity will come from green sources. In addition as no ICE cars should be sold after 2030, by 2035 the proportion of clean propulsion should be rapidly moving towards 100%

It looks like Oil companies are looking at the future beyond oil. They are definitely not all in

While there are still many right-wing networks that deny the truth to global warming – or increasingly admit the world is warming but suggest that humans have nothing to do with this (a hard thing to argue as the only thing that has changed is us and our carbon emissions- and the change is happening faster than anything we can find in the last few million years), fossil fuel companies do not seem to be making the Investments necessary to move their business in the timescale available.

DHL has ordered 12 all electric Alice cargo planes

While there is not yet a battery that can power a passenger jumbo jet, aviation is looking more and more likely to go electric at some point.

The Alice plane is a plane that when carrying passengers can sit around 20. In cargo mode it can fly around 500 miles. It can be flown by a single pilot, and can fly about 1200kg. Travelling at just short of 300 miles per hour, and taking roughly 30 minutes of charging for every hour in the air (it can only stay up for about 100 minutes) it is thought that using these planes will save about 70% of the cost.

Also, being simpler engines with far fewer moving parts, the planes are expected to have higher reliability and lower costs for maintenance.

Even more exciting, these ranges are doable on current batteries. As there is huge amounts of money going into battery research it is highly likely that in the future, the range of these planes will be able to be increased.
