Will the 8th great ape- the Tapanuli orangutan – survive the first 2 decades after being described?

It is just 5 years since the Tapanuli orangutan was described. Despite this Orangutan being restricted to an area of Northern Sumatra, it is more closely related to the Bornean Orangutan than the Sumatran one. This might be the clearest indication of how long this species has been separate from its cousins.

Tapanuli Orangutan, only described in 2017 is still threatened by various projects in the area

The Tapanuli Orangutan split from its Bornean cousins around 670,000 years ago, while chimpanzee and Bonobo were split 1.5-2.2 million years ago. Baffling, the Sumatran Orangutan split from both the Borneon and Tapanuli Orangutan 3.38 million years ago. For context, Humans split from our chimpanzee ancestors 4-6 million years ago (so not much longer) and gorillas split from their chimpanzee ancestors 7-9 million years ago.

All this is to say, that while the Tapanuli Orangutan is relatively closely related to the Bornean Orangutan, it cannot interact with it as it is on another island; and the Sumatran Orangutan is too far removed to be able to interbreed.

It is thought that the Tapanuli Orangutan has faced population decline of 83% in the last few decades (three generations). Further threats are numerous. One of its biggest threats is a hydroelectric dam, which would remove much of the remaining habitat, but a gold mine, loss of habitat and an expansion of croplands are other threats.

Unfortunately little to nothing has improved in the last 6 years, they are probably closer to extinction now than ever. If you have followed this blog over the last 5 years, you will have seen that I have written on this new orangutan species a few times. We will continue to follow this animal on this blog – we must work to raise its profile and not merely chronicle its slide towards extinction.

This is a wonderful 8 minute documentary on the Tapanuli Orangutan, the 8th great ape

The Indonesian rhinos that once roamed across much of Asia

The wildlife of Indonesia now often looks like relatively unique to those islands. This is not the natural state of affairs. 60,000 years ago, a cousin of the orangutan lived on the mainland. Unfortunately, what appears clear, is that humans were responsible for the extinction of these animals as with so many more.

There are 2 species of Indonesian Rhino, the Javan rhino and the Sumatran rhino. Now it should be noted that these names are not an indication of a small range (or if it is, it is wrong) in reality, both rhino species were far more widely spread. Indeed mainland specimens lived within the 21st century.

Another report stresses the importance of rewilding for climate change, and reintroductions

A report has calculated that the reintroduction of 9 species would do so much benefit to the ecosystems that they are found in, that these reintroductions would help us to keep global warming to 1.5° C.

While some of these would require human adaption, many would have benefits far beyond climate change.

These species are

Red Panda population has halved in the last 20 years, what is the future for the giant pandas little cousin?

Have you ever seen a red panda in the zoo? While the wild population has halved from 5000 to 2500. Yet at the same time the number in zoos has increased.

Although far smaller, the red panda can be fascinating to watch. Recent analysis shows it is not just looks, these animals are surprisingly similar

Europe now has about 407 individual red pandas and while figures are harder to find elsewhere, there are probably more red pandas now in zoos which in comparison to the giant panda population in zoos is around 500 world wide. Why is this?

Can nuclear fusion replace fossil fuels?

So, one of the arguments from the fossil fuel lobby for the last 150 years is that their product is essential. The fossil fuels are the only people who can produce the base load of electricity for the grid.

There are loads of other things that can take parts of this (this is the arguments that the fossil fuel lobby put forth) such as wind turbines and solar panels – the problem is that both of these are only available some of the time. If electricity can be carried many thousands of miles, then tidal power might be able to help with this but not in the near future.

When Nuclear fission was first brought in, it was predicted that this would be the perfect base load. Unfortunately not, people don’t like living in places where a meltdown might occur, there is a large amount of nuclear material created, which needs storing for very long periods of times.

Nuclear fusion is different. It is incredibly hard to get it working, taking vast amounts of energy, and goes out if it goes out of control. As a result, a nuclear fusion plant cannot melt down, and you could not make a nuclear fusion bomb.

We are finally making some progress, though as it has always been, predictions as to when it will be ready lie 2 decades out. As if on schedule, late last year the UK government said that the world first nuclear fusion plant could generate carbon free energy by 2040 (18 years out). It is true that the government is putting hundreds of millions of pounds towards this goal, but it is still to far out – in other words, if it takes that long, the human race will need to have cut carbon emissions to near zero without the help of nuclear fusion. Indeed even the EU has referred to it as a possible way to save us from climate change – however, given there is still so much research to be done, we cannot rely on this.

This plant in Nottinghamshire could be replacing coal power plants in the future, though coal is being rapidly phased out anyway. In theory, it is calculated that nuclear fusion could create 4 million times as much energy with the same space, as coal oil or gas.

It is an exciting prospect, and the UK is one of the countries leading the way, never-the-less we are no where near that yet.

Is the soft power of the fossil fuel industry slowing our move away?

The first papers linking carbon emissions and fossil fuel burning were released a long time ago. How long ago? Try John Henry of the Smithsonian Institution at the American Association for the Advancement of Science conference in 1856. Entitled, “Circumstances affecting the heat of the sun’s rays,” the paper was the first research linking increased carbon dioxide with warmer air.

That is 166 years ago!

We recognize that fossil fuels are the problem, yet their paid lobbyists continue to get access to politicians across the globe.

It is true that fossil fuel companies usually have little real power. Instead, they rely on the power they get through donating money to people of influence. How can we break this “soft power”?

What have they done?

Spent literally billions on controling the conversation about global warming, and changing the topic of the conversation. For instance what is your carbon footprint? Is something that they have pushed hard – by making everyone think about their own carbon footprint, they move who needs to act, from them to their customers. They also include creating so-called climate solutions, taking tiny percentages of their profits -in an effort to look like they are working for humanity.
They have also invested huge amounts into so-called education of the next generation (obviously in their way of thinking).
Funding of sports and other things that might influence young people, and in a similar way, arts and culture. Even allowing an oil companies logo to be put on a wall of a museum without explanation is likely to give them a subconscious boost, quite unfair – and something that the museum should never wish to do.

Orangutans are roaming into villages in Sumatra – bad news

At first glance, you could look at this headline as good news – in most instances, wild animals do not start looking outside their habitat for places to live, unless there are too many and they are being forced out. However, they also start looking elsewhere when they struggle to find food where they are, or as a result of encroachment.

In this instance it is thought to be as a result of construction of a hydroelectric dam. Perhaps more alarming, these are the Tapanuli Orangutans, which only number 800 and which if this dam is completed, will lose most of their range.

As the 8th great ape, it may also be the first great ape pushed to extinction and in their case as a direct choice of the local authorities.

The Thylacine or Tasmanian-tiger was declared extinct in 1936 but was it?

According to a study on the Thylacine, 1237 observation and claimed sightings have occurred of the Thylacine since it was declared extinct. There are reliable sightings into the 1980s or even later.

Last of the Iranian Asiatic cheetah cubs in captivity has died

3 Asiatic cheetah cubs were born in captivity recently. This was exciting, because this species is on the brink of extinction – there is only thought to be about 12 remaining in the wild, down from about 100 in 2010, a survey in 2017 stated fewer than 50 mature individuals.

Is this the last gasp for this species? Will the sight of a young cub like this never occur again?

COP 15 aimed to create a framework to halt the biodiversity loss on earth, what will its effect long-term?

COP15 ended with a hug biodiversity agreement, but will it succeed? Well that it is a hard question to answer, but I thought that 3 months after its signing, it would be worth returning to it and looking at what was promised!
