Why is climate change denial still not over? Because the amount of money that can be made by denying climate change.

Has there been a change? Yes, but not necessarily for the better. For many people (generally with a financial motive) they have gone from outright climate denial, to climate doomism – we have already emitted too much carbon, we are going to see global warming, so there is nothing I can do (this has the advantage of allowing those people to continue to behave in the same way). Climate doomism says, I am too little, I cannot do anything.

Boki the bear (2 years old) was found to have a condition that I also have. It is known as hydrocephalus, and is caused when the liquid that is found around the brain does not drain away properly. This is often found in infants, but can also occur after a head injury.

When this liquid does not drain, rather than protecting the brain, this liquid squeezes the brain, which apart from being very painful (it usually causes insanity before death, if left untreated in babies) but can take decades to kill naturally.

It seems quite likely, that this bear would have died relatively quickly in the wild, as even if the illness did not kill, it would likely cause different behaviour which would likely have caused more problems.

While it is true that bears have a sweet tooth, which may have contributed to this bears like for it, they are also very intelligent, and may well have been able to connect the idea of feeling better with the medicine that he was taking.

Pretty much all models that are trying to predict how much danger we are (on global warming) suggest that all current carbon syncs will continue to work, however, that does not appear to be the case.

We have emitted roughly 1500 giga tonnes of carbon dioxide since the industrial revolution, and the total amount of carbon dioxide in the atmosphere is 3200 giga tonnes. Before this point, there was roughly 2200 giga tonnes in the atmosphere. These numbers suggest that around 1 quarter has been absorbed by the planet (these numbers could well be wrong but are worked out from well known figures).

This suggests that at least 1 quarter of our emissions have been absorbed, which if this study is right, means 1 third more carbon being added each year, if we simply keep our emissions stable or conversely, we need to cut emissions by an extra third to meet our goals, if this holds true.

Given our difficultly cutting emissions so far, this is going to prove hard.

And yet, we need to do it very fast.

African penguins live in South African and Namibia, with a total population of around 18500 (13,200 in South Africa and the rest in Namibia). In south Africa, there are thought to be 2 colonies, with Boulders beach, near Cape town, has a population of around 3000 penguins.

In wilder places, one would think that penguins would be hunted by land mammals, and certainly these behaviours have been filmed, with me remembering footage of a brown hyena hunting penguins on the Namibian beach.

It has generally thought that penguins were relatively safe on Boulders beach, but it is becoming clear that the caracal, which is a smaller cat than a lion or leopard, are living in the area around boulders beach, and are likely the big predator of the penguins. It is true, that cape leopards live in small numbers in this area, and they have been known to take penguins, but being the apex predator, they do not live long-term in the reserve.

This is not the same with the Caracal. This documentary was done around the area of table mountain, but found throughout the cape.

One might argue that this is just natural behaviour, but the problem is that neither species is being able to live in a normal way. In 2016, 2 caracals were documented to have killed 130 penguins in just 2 months. It would not take much more than this, for the African penguin to disappear from South Africa, and indeed the world.
