Will climate change kill the forests of Africa?

There are many threats facing the great apes of Africa, from habitat destruction and fragmentation, to hunting for bush meat. Unfortunately, it is now thought that Chimpanzees gorillas and Bonobos face a still greater threat (assuming humans avoid killing off what remains of their population) the loss of about 94% of their remaining habitat due to forest die off from the warming that we are creating.

Could this become something impossible to see, within this generation? I hope not

Even under our most rosy scenario, they stand to loose 85% of their range.

The same studies suggest that as areas become unsuitable, there are likely to be other that become suitable. Unfortunately, dealing with slow adapting animals this will not help at all without significant assistance from humans.

What is even more scary is that this loss would occur by 2050.

I find this horrifying. I have not been able to yet visit any wild great ape populations, and now it looks as though their future is severely limited. It also looks like, by the time my children have children the huge forests of Africa teeming with wildlife, will be no more.

We must act now!

Human communities which live alongside great ape populations must benefit. Of course these communities must not grow and crowd out the wildlife, but if a similar system can be set up that worked for the mountain gorillas, perhaps many of the great apes could be saved and at the same time, pull millions of Africans living in poverty, into more sustainable and profitable lives.

This is not something that must be left to African governments. Indeed, it also must not be just left to tourism. Governments around the world, need to help in this work.

As well as replanting and recovering rainforests across the globe, the human population as a whole needs to work together to save the remaining tropical rainforests which are so precious to our future and that of our descendants.

A French company Biotope is working on sustainable cohabitation between chimpanzees and local communities in the highlands of western central Guinea.

The west African Chimpanzee once numbered around 2 million. Currently there are roughly 500,000, but without urgent action that number is liable to move quickly down to close to zero.

Conservation for its own sake is all very well for those people living on the other side of the world. For those who live close by it is a different matter. Ending the population explosion that is occurring in Africa, is essential both for the human and wildlife populations that share this continent. Similar programs could do the same thing in south America and Asia.

I am well aware that even if successful, this website will only be part of the solution, but I hope that with your support we can do some good.

A hydrogen powered world?

Hydrogen is an incredibly energy rich fuel. When Hydrogen is mixed with oxygen, a large amount of energy is released and the only waste is pure water.

The problem for many years has been that virtually all the hydrogen on earth is locked up as water. For a long time, it has been known that by running a current through water you can split the oxygen and hydrogen. Unfortunately, this process is incredibly energy intensive. Indeed it takes more energy than it gives.

Daily mail fear mongering over taxes on electric cars

The daily mail, a British tabloid newspaper, has a habit of writing sensationalist articles.

They have published an article today which states “Families could face new £765 annual green tax on cars as ministers plan new levies for electric vehicles to fill £34billion black hole left by the death of fuel duty” as its title – with details saying the figure comes from the AA later in the article (AA is a roadside rescue firm).

Now this is clearly click-bait. The article is written to make out that electric cars are going to have to be taxed far higher, in order to make up the governments funding. Now there are several problems with their arguement.

  1. The government spends roughly 1 trillion pounds a year, so 34 billion is roughly 3%. While this is significant, it is amongst the governments total spending, a rounding error. There are many places that the government could raise this money
  2. Public sector spending on roads in the United Kingdom reached 10.94 billion British pounds in 2019/20, an increase of 820 million British pounds when compared with the previous year.
  3. The improvement in air quality could see a noticeable improvement in health from a breathing point of view. Currently 11 billion is spent a year, on conditions caused or exacerbated by pollution. It would be conceivable, that the benefit to the countries health could alone increase productivity by 3%
  4. The reduction in carbon emissions is likely to lead to a reduction in money needed to be spent on mitigating the damage done

This is the standard form of article that the daily mail puts out, and indeed while there are very occasional articles that share concern for climate change, the daily mail has put out far more which take swipes at electric cars and any other way that the government might try to change our behaviour.

From an article as early as 2010, the writer claimed that the range will never be good enough bizarrely stating that they can drive their diesel car 800 miles on a tank – at motorway speeds, even assuming speeding that is 10 hours during which time you will need at least a handful of stops for food and a toilet break. Modern electric cars can gain 200 miles range or even more in 15 minutes charging.

Indeed, even last year they published an article claiming that 1 in 3 cannot afford an electric car. Now they quoted a figure of at least £2100 spent on their current car as the point at which electric cars would become affordable. By 2030 there are likely to be far more ‘runabout’ cars and similar, but the simple fact, is that most people will be spending at least £1500 on fuel a year. Given that electric cars last longer, and these people they are referring to, are likely to hold onto their car as long as possible, and probably do not buy new anyway we can assume the car is kept for at least 10 years. Electric charging is much cheaper, so you can be expecting to save at least £1200 per year, an amount that more than makes up for the initial higher price of purchase (the article states that entry level electric cars are around £5000 more expensive, so a purchaser will be better off after 4 – 5 years). There may have to be a change in car loan terms, to make borrowing more affordable, but this is all.

Articles on the difficulty of charging, range longevity and many more, are published every few weeks (or more regularly).

What is the daily mails problem?

Every country around the world seems to have a similar publication. Yes electric cars create slightly more emissions at manufacture (though this gap is narrowing) and yes they can be more expensive however prices are falling and the cost of ownership over the lifetime of the vehicle is significantly lower. Importantly environmental costs are far lower, and given the situation that the human race finds itself in, having to cut our emissions to zero pretty fast – caused I should note, largely by the sort of companies that newspapers like the daily mail praises constantly- we have no choice. The best impact that the daily mail can have is slowing the change. Given that the daily mail is based on a island, a place which stands to loose much from extreme global warming not least in terms of land. This sort of slanted analysis is only useful for confirming your biases.

It should be avoided (though the daily mail gives plenty of subjects to write on)

Lightyear one

The lightyear one is an incredible car. It is a highly efficient electric car, and gets over 440 miles from a battery smaller than the one in the long range tesla 3 which only has a range of 353.

This image is a wikimedia photo of the lightyear one and is shared under their standard license

This is partly because it is an incredibly efficient car – each wheel has its own, in wheel, motor. However, even more exciting, the car is covered in high efficiency solar panels – it has 5 square meters of solar panels, which is allow between 25 and 45 miles on solar power alone.

Manchin has made millions from coal since joining the senate, and he may be able to block Biden’s plan to halve greenhouse gas emissions

This website was designed to simplify wildlife travel – and we are making progress on this (slowly- terrible timing, given the epidemic), however without significant and rapid cuts to the worlds fossil fuel emissions, impacts from global warming will destroy many wildlife habitats so it is of importance.

Climate change is increasingly causing changes in rainfall. This is turning rainforests to savannahs and savannahs to deserts.

Without dealing with climate change, there will be far fewer ecosystems in which to save the wildlife.

This is why the USA is important. At this point the USA emits roughly 16% of the worlds warming gases.

The British government have decided to ban burning coal for electricity one year earlier in 2024

Coal is one of the dirtiest power sources, and increasingly around the world it is recognized that its burning must stop if we are to retain a planet easy to live on.

Later this year, there will be a climate conference held in Glasgow and the British government have been keen to make sure that it moves things forwards – if sea levels rise as much as predicted, life in the UK will change dramatically, not least as the UK could become an archipelago.

A reduction of African great apes of 80% by 2050?

Current prediction is great apes will lose 80% of their habitats by 2050

Of the great ape species, 3 out of the 4 non human species live in Africa. This is why it is so alarming the current estimates are that by 2050 great habitat will have reduced by 80%.

This is also a huge concern for the rest of the world. An 80% reduction in rainforest cover in Africa could make halting global warming impossible. 

Obviously there are multiple strands of global warming and halting species loss. Unfortunately this could sink both problems into impossible or near impossible to solve.

Furthermore, there are other sad facts about this idea. Farmland rarely benefits the people who live in its vicinity. The huge plantations of Indonesia have destroyed the rainforests but they have not lifted living standards, indeed in many places they have eradicated the ability for locals to live – forcing them to leave their home.

Game reserves require significant staff to look after the guests. Furthermore, there are a great deal of resources that can be extracted without destroying the trees above. This allows locals to increase their standard of living, while at the same time allowing the rainforests to stay standing and the wildlife that lives there to continue to thrive.

It would seem that it should be possible to dig deep mines under rainforests without cutting the forest down first. Obviously we come back to the problem of poaching that might increase with the mine workers, but the simple fact is that most mines do not disturb the surface (except for the mine entrance). It likely increases mine costs, but given the wealth of minerals that are thought to lie under the Congo rainforest it should be more than worth it.

I do not want to have to explain to my grand children, why there are no great rainforests left in Africa. I have only visited one rainforest (that of the Udzungwas in East Tanzania), but apart from the environmental services that these places provide there are many parts of the planet which rapidly turn to desert if you remove the rainforests covering the ground.

The worlds energy imbalance doubled between 2005 and 2019

The world is warming. This is something that is now essentially settled. Despite fossil fuel companies arguing the reverse, it was their research 40 years ago (and more) that brought the concerns of global warming first to the attention of humans (though initially they kept these discoveries quiet, and it has only come to light in recent years).

This new research shows that the world is now trapping twice as much energy as it was just 15 years ago.

As around 90% of this energy ends up in the oceans, this is a big problem. While the southern ice cap sits largely on land, the Northern icecap floats on the oceans. This is unfortunately one of the feedback loops that we know about. Ice reflects sunlight (and therefore heat) back into space. As the oceans warm this ice melts, replacing white reflective surface with deep blue absorbing surface – meaning that the oceans then absorb still more heat.

The unfortunate conclusion of the study was that unless this uptake of heat slows fast bigger shifts in climate should be expected.

World leaders are falling short again on delivering on their promises

One of the biggest issues that have been recognised, is that a similar route to prosperity is not open to the developing world. As Europe and north America developed their economy they emitted huge amounts of carbon – much of our power was created by burning coal.

In order to help developing countries jump this stage completely and move straight to renewables, the west had promised money. Developed countries had together committed to 72 billion a year to make this happen. While this sounds like a great deal, when you remember that without it, we are on course for devastating levels of global warming, it comes more into balance.

It was hoped that the G7 could boost this process in advance of Glasgow COP26. Given the G7 accounts for 60% of the worlds wealth, but its population accounts for only 10% of the global population, you would think that we could afford roughly 10 billion a year to be able to continue to live in a hospitable environment. Now of course, this is not all that we need to do – we also need to cut our own emissions to zero as fast as possible, however, there is much money to be made in this work.

The COVID epidemic has taken everyone’s attention off global warming. This is understandable, but we now need to refocus and make the changes that are required as quickly as possible.
