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.
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.
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%
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.
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.
For many years there has been concern about what will happen to the various ocean currents, as the earth and the oceans warm. One of the currents that has the biggest positive effect is the Gulf stream – and scientists warn that the loss of this current could have devastating effects on the world and must not be allowed to happen.
Unfortunately, we are not changing our habits very much at all, and certainly not fast enough.

Increasingly it is looking like, no one will see them in their natural setting unless you are travelling to Australia soon.
A mix of droughts, heatwaves and bushfires have all contributed to deal this huge blow to this unique species.
There are now estimated to be just 58,000 wild koalas, down for 80,000 in 2018. Another problem occurs when developers clear land to build a property – which is continuing to occur in Koala habitat.
Earlier this year, Australia announced that it was considering listing the East coast koala as endangered. With a precipitous fall in population like this, it seems odd that there is any decision to be made – of course the Koala is endangered, and if the government is considering listing a particular subspecies as endangered it must be very bad.
Estimates as high as 1 billion are quoted for the number of animals killed in the fires.
The increase of wealth in a few people is shown by the number of people that it takes to reach 50% of humans wealth reducing over time. in 2016 61 people were needed to reach 50%, in 2017 43 were needed.
Why does this matter? well it means two things. Firstly a large proportion of humanity has few physical resources. When you are living hand to mouth, doing anything else is impossible. The second, is that those few with enormous resources have vastly bigger carbon footprints: this is not just thinking of Elon Musk and Jeff Bezos and their rocket rivalry (it is not hard to make an argument that space could help save us in the future), but 22,000 with private jets and the many millions more who are emitting tens of tonnes of carbon each year.
Those with extreme wealth therefore need to offset a great deal more than just their own carbon footprint. Billionaires should be throwing money at people sequestering carbon – it will protect their own future just as much as the poorest on planet earth
Extraction of peat, generally means that it dries up and then releases its huge store of carbon back into the air.
There are vast areas of peat in places like Indonesia, and the DRC, however there are also large areas of peat in Scotland. Peat is full of nutrients and so it is valued by gardeners. Peat will be used by professional gardeners until 2028.
In the UK Peat is our largest carbon store, trapping as much as a tropical rainforest per hectare. They are also important habitats and protect those further down stream from flooding.
This has been known as an issue that the british government has needed to address for some time. In the end, it seems that they failed to address this with the urgency that it requires.
Most of the peat in the UK is imported from Ireland. However, they have banned it so this is soon to dry up. A ban is thought likely to cut emissions over the next 2 decades by at least 4 million tonnes.
It is a good start, but we also need to restore those peats that have already been part extracted. This could keep much of the carbon in the ground if we act fast.
It is unfortunately true, that we are so close to climate disaster that we need all large countries to move as one on mitigating climate change. What is to happen if just a few refuse? An article from a few months ago spells this out, and its not good.
If China Russia Brazil and Australia all follow up on the pledges that they made on carbon reduction the world and the rest of the world followed their example, we as a planet would be looking at warming of 5°C rather the 1.5°C that scientists tell us is needed in order to avoid terrible impacts.
