A recent experiment by google and American airlines, has shown that these could become far rarer which would help cut aviation emissions.
Through using AI models, contrails can be reduced by 54%. Given the impact on global warming (contrails absorb and trap heat really well), removing these contrails could make a big difference around the world.
So how big is this difference? Well planes only account for 2.5% of global emissions, but this increases to 3.5% with other effects such as contrails. A large part of this 1% is down to contrails, so by largely eliminating them, could cut aviation impacts by 2 sevenths.
Looking at it differently, a reduction of 2/7 or 29%, accounts for 2/3 of the emissions cuts required by aviation by 2050.
This does not really make a big difference to the overall issue, but shows that Aviation can still cut their impact in a meaningful way.
The UK watchdog (amongst many other groups) have concluded that hydrogen boiler is a stupid idea. It is true that its only waste product is water and oxygen, but the cost of making the hydrogen is very high.
Should there be large quantities of hydrogen sitting around, then this might make sense – burning hydrogen is generally a very clean fuel. The problem is, that it is almost impossible to store or transport it without loosing much on route, and it is incredibly expensive to split water – the current form for the vast majority of the hydrogen on the planet. Fossil fuel companies are keen, because their old methods can extract and split hydrogen, but it will mean large carbon emissions as well, so is useless – there is a reason that it is called grey hydrogen. Green hydrogen is the only kind that will give us any profit as a world.
So why is the government supporting the switch (alongside gas focused industry). The department for energy security and net zero stated this week that the gas network ” will always be part of our energy system”. I am not sure why anyone would look at it, given an air-source heat pump is likely to be around price parity, and ground source heating even cheaper.
Installation, at the cheap end will be far cheaper than a heat-pump, but this will be more than made up for over the lifetime of the device. Furthermore, with the grants currently available, you are far better off going straight to a heat pump. This is a waste of time and money, and it would not be remotely surprising, if you had to remove it before the end of its life,as it would be costing too much
Around the world there are around 3 billion cattle and sheep. These produce around 231 billion pounds of methane each year, which is around 10 billion metric tonnes of methane into the air. Remember that over the first 20 years (it reduces after this) methane traps roughly 80 times the same amount of carbon dioxide. So this is the equivalent of a huge amount of carbon.
To put this in perspective, if we shrink the worlds carbon emissions to zero, but are left with all this methane, we are likely to have runaway global warming anyway.
So what does this seaweed do? It essentially causes the cows and sheep to create less methane. How much? Well, while around 100 million tonnes of this seaweed would be needed, they could eliminate 98% of the methane emissions from these livestock!
In 2019 around 34.7million tonnes of seaweed was farmed, which is leading some sceptical researchers to suggest that it cannot be done. However, if we look logically, this is already enough seaweed to reduce methane emissions by 1 third – not to be sneezed at.
Another problem, is that currently Greener Grazing is restricted to only growing 1/3 of the year, as the water temperature kills the seaweed the rest of the time. However, this could be fantastic – if cross breeding can give this seaweed the ability to cope with warmer water, they might be able to meet the whole worlds demands.
More work is needed, and other tests have proved less successful in the reduction of methane, but still, this is a field, where we might be able to green peoples behaviour without requiring them to stop eating meat.
Now, of course, if meat grown in a lab could reach price parity, it may deal with this problem overnight, though it would also eliminate many peoples source of income.
Time will tell if this company is going to have a large effect or not. We need to have farmers wanting this additive, thereby creating a valuable market for coastal communities around the world.
This vast wind farm can produce around 3.6 gigawatts of power when turned on. To put that in perspective, peak demand in the UK is currently around 61 gigawatt hours, This means that even at peak demand, this wind turbine is capable of providing roughly 5% of the UK power demand. By contrast, the average house in the UK has a low-point in power demand, during the night, when around 0.2kwh is used an hour. This equates to around 5gigawatt hours. In other words, this single wind farm is likely to be able to deal with all baseload demands of the UK housing. Of course there is other demand, from shop lights being left on, to night shifts in factories.
However, what is clear, is that this is a significant amount of power, and is likely to greatly reduce the amount of gas required to be burnt for power production.
Given that this adds to the already installed stock, we now can create around 30gwh of electricity from wind – when it is at its peak.
Now, of course the wind does not blow at this required rate to produce the maximum amount of power 24 hours a day, so these numbers are not available all day.
To put these numbers in context, in 2022, wind delivered around 26% of UK electricity. Given all the large wind farms planned, this will grow.
Declared extinct in the wild back in 2000, this species is now not only re-established in the wild, but has a big enough population to now only be listed as endangered (down from critically endangered).
Apart from supplying individuals for the reintroduction, Marwell zoo also helped with strategy.
The video below is just 2 minutes long. While it talks about Marwells other work as well, it shows a number of these animals living wild back in Africa.
This has got to become the reason for zoos. What ever else they do, there are many species at risk of extinction in the wild, these need to have enough captive individuals to re-establish wild populations, should the current conservation fail.
Of course, zoos have many other roles, from education, to fostering a love of wildlife in the next generation.
One thing that they should not be, is a curio house- many zoos are far to worried about displaying albino or melanistic individuals. Now while these individuals are fascinating and can be used as ambassadors for the species, their genetic health should be looked after (all white tigers are descended from one female, and closely related individuals are regularly bred togerther to ensure this trait is passed down. Indeed, as a result of this, white tigers are often not of good health.
The majority of zoos are now like Marwell – while like many, it started as the private zoo of wealthy owners it has turned into an important place of conservation and science. Another of their successes, is the cooperative breeding that occurs as standard in current times, across Europe. Regular loaning of animals is essential, so that we can treat all of the zoo animals in Europe as one single population, thereby making sure that all animals in the system are healthy.
There are many hundreds of zoos across Europe (some claim as many as 2000, though around 1500 is the estimated worldwide number suggesting that this is a rather large exaggeration. It is likely that around half of the worlds zoos are in Europe, and by cooperative breeding, we can make sure that healthy populations remain in captivity, so that should a population be lost from the wild, it can be returned, when the wild situation improves.
Almost all predictions about human population are expected to peak in the coming decades, and then decline after that. If this pattern is followed, it should be expected that we will need to re-establish wilderness in the future.Â
Scimitar-horned oryx have been returned to the wild in Tunisia, and Chad and there are plans to return them to the wild in Niger, in the near future.
Extinction was caused by a variety of features, but the primary one was over-hunting. This has virtually been eliminated, after a ban on hunting of this species was put into effect in 2013. Should this species be allowed to fully recover. In 1985, there was a population of at least 500 of this species living in the wild, so it took only 15 years for it to disappear, as such what is clearly essential is a regular assessment on how this species is faring, allowing earlier interventions.
Saving the natural world, may require this kind of success to be a regular feature.
Once so common that they were cooked as a national food on the island. Yet in just two decades, the animal is one of the rarest in the world, with an estimated population of just 21.
Growing to 20cm long and weighing over 1kg, it was one of Dominica’s apex predators. eating small mammals, snakes and other frogs.
It’s decline is notable, as its calls were formerly something that you heard across the island.
Now, silence from this frog has fallen across most of the island.
Initially, its decline was caused by a fungus, which impacted amphibians skin – important, as many amphibians breathe through there skin, and all breathe through their skin.
The breakout of this fugni led to a decline of 80% in just one year. Known to only occur on one other island (Montserrat), scientists urged strict quarantine measures to stop it arriving, but these warnings failed to have any effect.
A number of these frogs were removed in 2009 as the illness began to spread, and they are housed around the world in various zoos, such as London zoo.
In recent times, a few surviving individuals have been discovered. These appear to be naturally resistant to the chytrid fungus that is at fault.
Unfortunately, shortly after, hurricane Maria hit, and the population declined a further 80%, back into double digits.
Due to the lack of immunity to this fungus, it would appear that zoo individuals that were rescued back in 2009 are all irrelevant. Whether with such a small wild population, it is worth capturing more (it is possible that these new individuals could be bred with already captive individuals, bit this may not retain the immunity).
The remaining wild frogs are found in 2 populations, and neither are found on protected land. As such, the situation could change fast if land use changes would occur.
The conservationists in the wild are still working, but it is thought that there is only 2 years left to save the species from extinction.
The Algonquin wolf, also known as the Eastern wolf is a species which has been discovered in the eastern USA and Canada (click on the bold name above, to visit the species page).Â
Perhaps, understandably, it is hard to find a new species in the USA unless it is already pretty rare. This species is only thought to have around 500 individuals, throughout its range (eastern USA and north into Canada).
South-eastern Canada has been known for a race of wolves and coyotes, that do not appear quite right for some time. This study suggested that this group of wolves split from the rest of wolves around 67,000 years ago. This appears to recent to give rise to the significant genetic differences, but it appears that this population also bred with coyotes around 37,000 years ago, and has continued to have genetic exchange between both species (on occasion) since.
As such, it is suggested that the Eastern wolf largely owes its appearance to hybridization between all three.
Has this lead to a more successful species? Well, one may well suggest not, given the small number of these wolves that survive at this time.
However, this is a well settled part of North America, suggesting that in fact it could be down to human hunting rather than natural forces.
At the current time, countries in the region in which the COP is held will chose a president. In theory, that is fine, however, in practice if this is going to continue then the middle east should be banned from hosting the conference.
So, what precisely did Sultan Al Jaber say, which was so troubling?
Firstly, he claimed that a ‘phase-out of fossil fuels would not allow sustainable development “unless you want to take the world back into caves'”.
He then claimed that there is ‘no science’ to suggest phasing out fossil fuels is the only way to achieve 1.5C.
After being laughed at, over this utterly insane statment, he suggested that the comment had been misinterpreted. It should be noted, that this was in response to a question from a woman, which he was relatively rude about.
Do you think this woman misunderstood?
He even had the gall to suggest that the misrepresentation was undermining his desire to reduce carbon emissions (perhaps if this is true, it can start with his huge fossil fuel company can show this?). More than 100 countries are already supportive of this.
The worlds uptake of electric cars must accelerate. This is partly underway – last year around 67 million cars were sold, but 14% of these were electric, up from just 9% the previous year. The uptake is accelerating.
It should also be noted that apart from extreme heat in the UAE, continued global warming will also damage the UAE in extreme ways. The UAE economy is 0.5% of the global economy, in the end, places like this may refuse to accept the end of oil, and will have to be bankrupted, as cars move to 100% and many other industries clean up their act.
This bear was filmed, gnawing on a bone from a takin, a species of wild cattle.
For a species which is thought to survive exclusively on bamboo, this would be strange behaviour.
However, pandas do not survive exclusively on bamboo as roughly 1% of their diet comes from other foods. In fact, their digestive system is typical of a carnivore, so the remaining 1% of their diet can include eggs, small animals and carrion – like this bone. Pandas are also known to forage in farmland for pumpkin, kidney beans, wheat and domestic pig food.
The thing is, pandas eat up to 38kg a day, which means that during the week, they eat around 3kg of food that is not bamboo. This is significant, and while much of this may well be other vegetation, if the time spent on other food sources was around 1% of the time, it would suggest at least 1 hour a week spent eating other things.
One must remember that their intelligence is on a par with Chimpanzee and gorilla -like other bears, so they are capable of working things out.
As if it is needed, here is a list of evidence that global warming is true, laid out by someone with a doctorate in the subject material. Do share with friends who have suggested that there is not.Â
It is simple, the world is warming and we are causing it by burning fossil fuels. We are responsible and so we can do something about this.
At a time, when there is a high probability that someone who denies all obvious facts on this subject, is leading the race to return to the white house, we need to stop debating facts and fix the problem.
USA, you are currently a pariah around the world, because you cannot pass meaningful climate action. You have 4.23% of world population, emit around 16 tonnes per head on average – which amounts to 14% of global emissions or around 1/7. It is true that China (29.18% of global emissions), however India emits just 7.09% of global emission. Yet the per capita emissions of these countries are 7.44 in China and just 1.89 tonnes in India.
The UK, a similarly developed country, only has emissions of 5.6 tonnes per head
We’re hoping to return to a more normal amount of blogposts in the near future. Time is currently going into building a database of species of the world.
