There is a variety of different causes for deforestation. However, the majority of the work is usually done by individuals – often for subsistence farming, though often the land is only fertile for a short period of time, requiring more rainforest to be cut down.
However, if people on the ground know that cutting down the rainforest will make life worse, then they will not do it.
Efron Simanjuntak (clickhereto see a photo in a new window) was once a successful logger (illegally) in Sumatra. In 2017 he was caught, and in 2018 he was imprisoned for 2 years. In these two years, he had a lot of time to think, and realized the damage that he was doing.
One of our systems is not working as it should be, hence the wrong look today. It has been disabled, which is allowing the website to run, but will run slower and not quite right until we fix, sorry for the interruption
We will put out more articles, while we try to fix the underlying issue

This plan was dropped in March as a result of Hungary blocking it, as well as Austria and a variety of other groups. It is unfortunate, that often in order to meet an agreement, the environmental rules are often watered down so much as to become meaningless. It was cleared, after Austria changed its mind (it should be noted that the Hungarian MEPs were in favour and it is only the Hungarian government that got in the way – as they often are; unfortunately the leader of Hungary Victor Orban is not helpful, and is often the block for the EU. Whether this will change in the near future is anyones guess.
Still this will have to be implemented across the continent to be useful. Having said this, should it be successful it is likely to have a big impact.
Increasingly, it seems Shell is a company which repeatedly makes pledges when the light is on them, and then backs away, when no one is looking any more.
In the summer, they dropped a pledge to turn 1 million tonnes of plastic a year, back into oil. They now say that this goal is unfeasible. Advanced, or chemical recycling, involves breaking down plastic polymers into tiny molecules, ready to be reformed into something else. The most common method is called pyrolysis – which uses heat.
They first used pyrolysis in 2019, when they made oil using this process in a Louisiana chemical plant. It should be noted, that this uses so much energy, it is likely to be worse for the worlds climate than continued use of virgin plastics (this is not to say that we should, but that this is not a viable solution). Shell has suggested that this pledge is impossible as a result of not enough plastic waste coming back to them, but as hundreds of millions of plastic is created each year, this seems rather a cop-out.
They are not the only company to back away, but they are the latest. It should not be possible to get off the hook by simply making a declaration, but instead should require them to do something else that will have a similarly positive impact on the world
The UK has set a hard target of 100% green electricity by 2030, but unfortunately, at the current time, its investments are not keeping up with its targets.
It is estimated that the UK need £48 billion to get to this target in time. This target would require a doubling of the onshore wind capacity, a tripling of solar power and a quadrupling of offshore wind capacity.
The current thinking, is that the UK is just half way to the wind energy target in 2030, however with solar it is worse. Currently we have roughly 15GW installed capacity, but it is predicted that we need 70GW to meet our target. Current progress suggests that we will hit 44% renewable by then, which is far short of the 69% that would be required.
What is worse, is that at this rate, gas will still account for 29% of energy which would be more than the individual contribution of Solar, onshore wind or offshore wind. It should be noted, that it is thought that meeting this target on time, will be worth far more in savings, but there does not seem to be enough urgency from the UK government to push this forwards.
It should be noted, that we have just had a change of government, and if Labour continues as it has started, we should get back on track.
In the summer, a government report found that the policies put in place by Rishi Sunak were only good enough to meet roughly 1/3 of the carbon reduction that we had pledged to make in the Paris climate agreement of 68%.
A study, using detailed 3d surveys, found that road building, and other degradation is causing 5 times as much carbon to be released into the air, than deforestation of the Amazon.
From road building, to selective logging, fires and natural disasters, all these activities are combining to having a greater impact on carbon stocks in the Brazillian Amazon than deforestation. This huge discrepancy is not taken into account by the numbers.
This is also a problem to the world, as this carbon is being radically underestimated, which means that large quantities of our remaining carbon budget are being used up. This new survey used lidar, which gives a more accurate idea of what is left in terms of forest cover.
With the addition of lidar sensors on the ISS, it is possible to scan the worlds forests more often – and given the ISS regular passing over 90% of the earths surface (in each 24 period – as while it orbits on a set path, the earth turns below it) this can be a good tool to keep an eye on the forests of the earth.
Another confirmation (as if it was needed) has been supplied by this study, showing that Indigenous territories and conservation units are both more efficient ways to protect the forest. These cover only 47.5% of the land, but contain just 9.1% of the forest clearing 2.6% of the logging and 9.6% of the fires.
Talking of fires
Fires continue to burn in the Amazon, with over 13,400 having been recorded in 2024. President Lula has called for general mobilization and Brazil has pledged to end deforestation by 2030. This is higher than during Bolsonaro’s time in office, though current cause is a drought, not human mismanagement.
Climate change is causing an increasing change in weather patterns, and reduced rainfall is changing the forests behaviour ( it should be noted, that the forest produces a not -insignificant portion of its rainfallm
Marsupial bones have been found on islands hundreds of km from Australia. What is more astounding is that these moves appear to have occurred 42,000 years ago, and could not have taken place without humans. Found in some of the islands, which form a chain from Asia to the Australian continent (though there are still hundreds of kilometres between them.
Found within rock shelters within these islands, were a layer of sediment, which included signs of human presence. Amongst this layer, was also found bones of marsupials (there is no other evidence that these animals ever lived on the island). This island is over 150 miles from the nearest place that these animals could have been found, which is unlikely to have been survived for a crossing (though it should be noted, that animals are thought to have crossed from Africa to Madagascar on similar rafts, and this is 250 miles.
We continue to move species, and often in quite damaging ways. Still it is interesting to know how long we have been doing it.
I wrote (several years ago) about the odd attacks orca were making on boats off the coast of Portugal (around the straits of Gibraltar). Unfortunately, this behaviour has now spread to French waters, with 2 orca ramming a sailboat of northern France, damaging the rudder so badly, that coastguards had to tow it back to land.
While this is in a new area, this is one of nearly 700 attacks by orca on boats along the Atlantic coasts of Europe since 2020 – with around half of these attacks causing mild to serious damage. The Orca tend to attack the rudder, making it impossible to steer the boat.
This behaviour has been linked to a group of 35 Iberian orca, from which 16 individuals engage in these interactions (4 adults and 12 juveniles).
It is unclear what causes this behaviour. Some experts have suggested that it is a form of misbehaviour in teenage orcas, though other suggest that it was actually a result of an animal being entrapped at some point by a sailboat – causing phsycological trauma – leading to a need for revenge in the population. This may have been the same orca, as they tend to follow their prey of Atlantic blue-fin tuna north to the Bay of Biscay (in the summer) so these could have been some of the same animals.
It should be noted, that this is still thought to be restricted to a small group of animals (especially if it is shown to be members of the original group), and so people should not fear orca as a species.
The Ross ice shelf is vast, covering 182,000 square miles, it is only slightly smaller than France, and yet a study has shown, that the whole ice shelf can move 40 cm in just 10 minutes. These were generally caused by slips in the Whillans Ice Sheet, which is one of just a few ice flows into and through the area.
The whole shelf was found to move 6-8cm once or twice a day, triggered by these flows moving. This could be the cause of both icequakes, and fractures running through the ice (fractures are important, as they make it more likely that a section of the ice will break off the edge of Antarctica and head into the ocean. While this ice can, on occasion survive a long time – A23a broke of Antarctica in 1986 and has been floating free for much of the time since (except for a decade or so when it grounded); it was estimated to be 400m thick and weigh in at nearly 1 trillion tonnes.
This is a problem for a simple reason. Unlike the north pole, there is land under the ice in Antarctica. This means that while in the north pole, the ice sheet is already in the sea, so its melting cannot increase sea level, Antarctic ice all does increase sea levels.
The Ross ice shelf is known to have collapsed 120,000 years ago during the last interglacial period, and contains enough ice to raise sea levels by 11.5m (this would also cause another 2m of sea level rise because of the glaciers which would no longer be held back).
A Dutch startup, is trialling mitigating this in the Arctic, by pumping sea water onto the ice. This then freezes, thickening the ice. It is possible that this might work in the short term, however, what is clear, is that the only long-term solution, is to stop burning fossil fuels, so as to halt the heating of the earths climate.
These 3 groups do not intermix, and only very seldom, interbreed. These populations are found in the Southern Pacific, Northern Pacific and the North Atlantic and Mediterranean.
This naturally means that the great white sharp is far more at risk of extinction, than if all the great white sharks in the worlds oceans could interbreed.
These areas appear to be bounded by great ocean currents, which are rarely crossed. This is a problem, as if an individual population is lost, it makes it far more likely that distinct genetic information could be lost with it – take the Mediterranean great while shark population, which has seen a dramatic population decline from historic numbers, estimated at between 52% and 96% (areas like the Maramara sea, are known to have lost 96% of their population) depending on which study you read.
This makes local conservation far more essential, and we need to be careful to not loose any individual populations. There has been a great deal of worry for the great white shark population around South Africa, as they pretty much vanished in 2017, but appear to have returned in 2024. The disappearance of the great white was attributed to 2 orca which had become expert in hunting and killing these sharks – it should be remembered, that while great whites are often at the top of the food chain, they are hunted for food by orca. Whether these orca have gone back to eating something else, hence the great white shark return, is a question that does not appear to have been answered as yet.
