Climate stripes – a clear way to see global warming over time
This image is a fantastic way to be able to see climate change. Created by Professor Ed Hawkins in 2018, it shows the changing in temperature over the last 2 centuries.
Blue lines show years where the yearly average temperature is lower than the overall average (and the darker the further below the average). The red is the opposite.
While it does not need pointing out, can you see how dark it has got in the last few years.
Below is a short video about the stripes with their creator explaining them.
Currently, land given over to growing animal feed accounts for 40 million square kg (15.4 million square miles). Given the worlds land mass accounts for almost 60 million square miles (160 million square km( this is a significant increase). This amount of land, freed up, could potentially allow a huge improvement in the amount of space given over to wilderness on the earth.
So where would we get protein for livestock feed?
Chinese scientists have created a method which allows the conversion of coal into protein – far more effectively than with plants. 0.1% of this land is required in this new system. It is true that this still accounts for 60,000 square miles,
So the process has a number of steps.
The coal is transfored into methanol via gasification (this can now be done with a near zero carbon emissions)
The methane is then fed to a special strain of Pichia pastoris yeast, which ferments the methanol, in order to produce a single-cell protein complete with a range of amino acids, vitamins, inorganic salts, fats and carbohydrates. There is far more protein in this than in plants and it can be used to partially replace the protein currently used
The conversion efficiency is at a remarkable 92%. This means that it is a cost effective replacement. Now, how much of the protein can be replaced, however a trial facility has already produced thousands of tonnes of this protein.
So if we assume that it cannot replace all of the protein, it seems reasonable to be able to replace 50% or 80% of the protein.
Even countries like the USA could free up thousands of square miles.
The idea that we could free up 30 -48 millions square kilometres (7.5 to 12 million square miles) to be returned to wilderness and carbon sinks among other purposes. If just half of this land was rewilded, it would allow large amounts of the land around the world to return to a wild state, which would help us cut emissions.
Now, it is true that this coal will be emitted as carbon at the end of the line, but if enough of the freed land is used for forest and similar, the net carbon gain can be huge.
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.
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.
Back in 2019 NASA wrote an article, talking about planting trees as a way of doing part of the work for mitigating climate change. By looking at satellite images they looked at areas that were recently deforested, or areas which would be easily turned into forests. They came up with an incredible number of 900 million hectares (2.2 billion square acres). If all these areas were reforested with the right trees for each area. Apart from suddenly increasing the worlds forests, and giving breathing space for many species on the verge of extinction, the calculations suggest that these lands would take around half a trillion trees – it would increase forest cover by 25%.
Calculations suggest that the carbon that would be emitted would account for around 200 gigatons of carbon, or reducing carbon emissions in the atmosphere by around 25%. Now alarmingly, this is only around 20 years of current emissions, so it is not the only thing that we would have to do.
Even planting half a trillion trees is not an end of climate change – this is how much emissions we have emitted – but it would be a fantastic start.
This 1.5 degree Celsius target has been talked about as increasingly impossible to meet. However, this target is essential – many of the worlds low level islands long-term survival leans on this.
Here, an expert is suggesting that we might survive. This is some positive belief that we have been in short supply of, in the last few years.
“Despite the scale of the challenges, I feel more optimistic than i felt two years ago” he added “Solar photovoltaic installations and electric vehicle sales are perfectly in line with what we said that they should be, to be on track to reach net zero by 2050, and thus stay within 1.5C. Clean energy investiment in the last two years have seen a staggering 40% increase”.
We are by not yet there, it is very much the case that we need to keep working hard.
The targets that he set, include a tripling of clean energy by 2030 and a 75% reduction in methane emissions by the same date, and a desire to see these targets come out of the COP28.
The referendum on Yasuni reserve will benefit a huge range of species, along with several groups of uncontacted tribes of indigenous people. The vote was not close, with 90% of votes counted protection won by around 20%. It will also keep around 726 million barrels of oil in the ground. Given that one barrel is 158 litres, that is 114 billion liters of oil, and as each one emits at least 3 kg of carbon dioxide, this is going to save 350 billion kg of carbon dioxide released into the air. This is a huge win for the environment, but also for the wildlife of the Yasuni reserve.
While an increasingly large number of people are switching to electric cars, there is a growing concern that this change is not happening fast enough.
Currently the EU sells 10 times more electric cars than just 6 years ago, which is impressive, so what is the concern.
Might this be the future of motorway rest stops?
For many people, they believe that their next car will be electric, but a large portion of people are awaiting a big crash in prices. This forgets two things, firstly that with electric cars, much more of the cost comes at the beginning, so it may well be that electric cars are always slightly more expensive. One of the things being learnt is that it is not enough to incentivise electric cars, you also have to disincentivise combustion engine cars.
There are places where this is working well, such as central London, which has a congestion charge, but this is not charged on electric cars. It is true that this is going to end soon, but still should give a reduction for those driving electric cars. However, it means that in places like South Kensington, the number of electric cars is shooting up.
There are a variety of help across Europe, with Romania offering over 11,000 to help, or France having a scheme for poorer households to allow them to rent an electric car for only 100 euros a month.
The dramatic rise in electricity prices since the start of the invasion in Ukraine has also not helped, as if there is not cheap electricity at night, the saving are far lower than they used to be. Will Europe hit its targets? I think there is still work to be done, but it is certainly moving rapidly in the right direction. I look forwards to every motorway stop being like the all electric gridserve (look at the fullycharged episode below).
