What should we do do with wilful misunderstanding of accurate climate predictions

I was watching a YouTube video on Tuesday which raises an important point.

Why do people on the whole continue to believe climate science is not settled, or that all of climate science predictions have been way out? This is not generally a belief that we come to on our own, it is usually fed to us by vested interests (either directly by fossil fuel companies, or indirectly by a publication which is sponsored, though this sponsoring is not always clear).

One of the most disgusting ways they do this, which is raised in the video, is by looking at a graph with a number of possible future lines. They then ignore the lines that are accurate and clearly mimic the warming that actually occurred, and simply leave the graft lines which were an extreme prediction in one or other direction.

 

What can we do about this? Our animal brains tend to pick and choose evidence that support the views we have already come to – this process often occurs without us even noticing.

It is therefore quite problematic if people are giving us a view of these climate science predictions from the past (in this case the graph created by a climate scientist called Hanson back in 1988, he plotted four possible temperature patterns, and one of them predict real-world temperature rises to a terrifyingly accurate degree.

So what people have done is to take an extremely clever piece of climate science that has accurately predicted the temperature rises over the last 40 years, and made a significant number of people believe that he had it completely wrong.

 

Now it is true that if you have an inquiring mind, one article is not likely to sway you. However, if, like many other people you believe something similar to what is being said in the article you are likely to trust it and may not search out others to check the veracity.

As the video shows, many vested interests have simple shown (as you see in the video) the observed temperatures (black line) and Scenario A (the red line). It is true that Scenario A overestimated the warming that we would experience. However, that is precisely the point – Scenario A represents what would have happened if humanity had continued as though there was no warning.

But that is not true! Many people would argue that we are not doing enough (and it is hard to argue this isn’t a legitimate concern) but we have done something.

Carbon emissions in some countries have fallen dramatically. This is nothing to the amount of cutting that is required, but we have made progress.

Hansens actual prediction of where we would stand at this point, is scenario B. This at the point of the last actual data is right on the money. Actual observational data always takes time to come in, so we are yet to see if observational data will follow the latest rise that Scenario B shows. But it is surely clear to even people who rarely use maps, that predictions of the last 30 years have been alarmingly close to what was predicted back in 1988

What can we do?

The simple fact is that the climate science on global warming is settled. When politicians try to run on a concept that goes against this they should be called out for it. It is true that democracy does not always give you the best candidate. In recent times we have lived through for years where America elected a person who believed things that were totally out of line with established science.

We need to reach a point where if someone is stating something as fact which is clearly not, not only should they fail to be elected but the falsehoods they have spread should be corrected.

Furthermore, businesses that are responsible for large quantities of pollution should not be able to get away with whitewashing their responsibility. Look at who you are giving your custom to. If they are damaging the planet, and you are paying them for services then the damage is in your name and you are responsible (morally if not at the current time financially).

As consumers we have a great deal of power. Sure we want good quality items that don’t cost too much, but we also do not want them to harm the planet. Engage with the businesses, if they are doing things that are bad for the planet. If they will not engage with you, then stop buying anything from them! If large numbers of their customers decide to go elsewhere businesses will quickly change their ways.

It was always foolish when Donald Trump stated that some action was too expensive.

Humanity will have to pay. If we do not pay to fix our mess now, then future generations will suffer the consequences.

If we do not act now, we are passing on the responsibility to our children and grandchildren – and they are likely to have to pay tens or hundreds of times what we considered too much. The cost will be paid, the bill that we are currently saying is too high, is tiny compared to the costs that we are passing on to our children. This is one of the issues with democracy – it is all very well to say that democratically elected leaders will work in the greater good, but the way elections work they only have to take into account the current voters. It is our job to make sure that short term policies do not win elections.

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.

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.

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.

Sea-lion struck down by epilepsy – brought on by global warming

There is an increasing problem of sea-lions off the coast of California becoming epileptic as result of global warming.

It appears to be caused by domoic acid poisoning, which in the wrong circumstances builds up to dangerous levels in shellfish and other sea animals in the area. 

Domoic acid can be released in large quantities during algae blooms, and due to global warming algae blooms are happening far more often.

Another animal this is prone to this problem are sea otters. Given the historical damage we did to the sea otter population, unfortunately lee6 could do substantial damage.

Scientists have found treatments that will allow them to deal with animals affected,however it may become necessary to find methods of making them affected instead as algae blooms will become more and more common as the temperature of the water’s increase.

Hundreds of koalas have died in forest fires as they burn their natural habitat but they are not threatened with imminent extinction

Koalas as a species, are highly popular. Not found in many zoos a lot of people go to Australia to see them. Perhaps down to the character Binky bill, and the books written about him, koalas are one of the species that almost everyone knows about even though the majority of people haven’t seen them. In the UK only found and in Edinburgh Zoo and Longleat Safari Park, ( with both these arrivals relatively recent) zoo goers are not used to seeing koalas.

Wildlife species only found in Australia are threatened by several factors. The first is the fact that Australia is increasing the clearing their habitats- as in Africa, forest living species cannot survive in the wild when their habitat has been cleared, and unfortunately in Australia large parts of their land are being cleared. While on occasion that has been pledges to replant Forest elsewhere in Australia, generally the firm has either failed to live up to its promises or has not replaced it with like the like- often the new forests are fast growing species that do not support the wildlife of the forest they destroyed.

Australia is one of the countries that is being hit first by global warming with parts of the Continent becoming largely uninhabitable. The increase in temperature is also drying out the forest which is meaning that some of the forest not being cut down are dying anyway.

Over the last decade also Australia has had some politicians who have been prominent climate change deniers, and thus far they seem to be uninterested in doing the things that are required to protect their own way of life.

In this latest fire, hundreds of koalas have been burnt to death, unfortunately the area was actually a highly successful breeding ground and had very high densities (remember that koalas are herbivores and therefore can live at densities of hundreds per square mile).

However sensationalist claims that koalas functionally extinct after these fires is totally false. They are highly endangered with their habitats disappearing at an astounding rate, but be functionally extinct they need to be very few members of the Species left and we are not there yet (functional extinction essentially says without human intervention the species will disappear). There are arguments as to how many koalas are left, but it’s estimated that New South Wales has between 15,000 and 30,000 remaining.

Koala numbers declined by about 40% between 1990 and 2010, so the theory is without a change in the government’s attitude very soon the Koala will be totally extinct in the wild. Isolated cases of reforestation need to be increased and and Forest corridors between blocks would allow the population to rebound naturally (this adds resilience to farmland as well as the wild areas around).
