The UK clean energy targets will be missed without £48 billion

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%.

Currently, in the Amazon rainforest, 5 times more carbon is released from degradation than from deforestation – and still what remains continues to burn

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

It appears that humans have been transporting wildlife around to new places for longer than we thought

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.

Orca now attacking boats off the coast of France

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, in Antarctica, has been found to move

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.

Great white sharks separated into 3 district populations 200,000 years ago – and have Orca stopped hunting the South African population?

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.

Surely, there is a problem when a Southport rioter gets jailed for less time than a Just Stop Oil protester?

Rioting and protesting are both activities that many would consider annoying. Yet, they are very different. Rioting, is a totally illegal activity, and the rioter in question punched a police officer in the face – he was given 3 years in prison. The Just Stop Oil protester was involved in a zoom call to talk about blocking the M25 and was given 5 years.

Peaceful protest is a protected right in the UK. It is true, that blocking a motorway is not covered, but there is an increasing part of the UK population which are so worried about this, and the governments low priority of this, that they could condone action like motorway blocking.

This law was only passed in 2022, and appears to be a direct attack on the right to peaceful protest. With Labour having recently taken power, we would hope that this ridiculous expansion of powers, and destruction of long-valued British rights might get reversed, but we will have to wait and see.

Plans to turn the Pantanal into a waterway, will destroy this wilderness

Site Icon

The Pantanal is an incredibly wilderness, however, the Paraguay river is planned to be turned into a water way and build ports. I have included 2 videos for you to look at (depending on how much time you have). The video above is around 4 minutes, while the below is a full documentary 50 minutes.

Could the recovery of the Goshawk save the red squirrel?

European Goshawks were extinct in Britain at the end of the 19th century (and remained rare for over half a century) but in the last 50 years have made an incredible comeback. In the new forest, in the south of England, there are thought to be hundreds of pairs living wild.

In Thetford forest in Norfolk, an estimated 52% of the goshawks diet was grey squirrel. While it is true that they will also take red squirrels, these are generally better at escaping. More importantly, it is thought that Goshawks could be used to stop the grey squirrels population from growing any further.

As I have written before, the pine marten is also important for the recovery of the red squirrel, as it is far more successful at hunting grey squirrels, and they generally do not cohabit in any part of the country.

This will likely not eliminate the direct need for grey squirrel population to be culled by humans, far from it, but may well help towards the idea of giving red squirrels breathing room.

Older trees are more capable of increasing growth and carbon dioxide use than young ones

Whether tropical or not, old growth forests absorb far more carbon than new trees, and can increase this

Old growth trees, have the capacity to greatly increase their growing rate, when there is a lot of carbon dioxide in the air. This has been found, in a study by the University of Birmingham. This is important, as in many places around the world, an area of destroyed natural forest, is considered to be replaceable by a similar area of planted trees, but what is clear, is that in order to merely keep up with the absorption of the original trees, several multiples more of trees need planting. What is worse, is that this is not worrying about the huge amount of carbon that is stored in the trees that are cut down, or within its roots system and the surrounding soil.

To put this in perspective, at the current time, it is estimated that a football pitch of primary forest is lost every 6 seconds.

This experiment was done, by piping extra carbon dioxide into a forest area and monitoring its growth. Unfortunately, this does reinforce the conservationist point of view, that simply planting a similar area of woodland for each bit lost, is not good enough.
