The Northern Forest: 10 million trees planted in the north of England
The Northern Forest project started back in 2018 to transform the landscape across much of northern England.The area covered by the scheme is said to be home to 13 million people. However, only 7.6% of it is covered by woodland, which is a lot less compared to the UK average of 13%.It's hoped the planting of 50 million trees will benefit local communities and help wildlife thrive.Lots of places have already benefitted from the project, including the areas around eight fire stations in Greater Manchester and Oak Road Playing Fields in Hull, which is next to a river prone to flooding.
Why are trees so amazing?
Trees are 'tree-mendous' for the environment, and here's why. They can play a really important role in tackling some of the effects of climate change. Carbon dioxide (CO2) is a greenhouse gas which is released into the atmosphere when fossil fuels are burnt. Scientists say it causes heat from the sun to be trapped, causing temperatures on Earth to rise. But trees work as an air filtration system, absorbing carbon dioxide from the atmosphere and converting it into oxygen, which is released into the air. That's not all. They also provide a home for lots of wildlife around the world. They can help reduce flooding too, by absorbing some of the water and reducing erosion.

Endangered crayfish returning to Nottinghamshire waterways
A rare species of endangered crayfish is slowly returning to its natural habitats, environmental experts have white-clawed crayfish is the UK's only native species, but it has been under threat for a number of years, particularly following the arrival of the North American signal crayfish in the North American crayfish competes with other native species for food and habitats, and also carries a deadly fungal disease called the crayfish plague, which has been rapidly killing the white-clawed the white-clawed crayfish is now returning to areas of Nottinghamshire following work from environmental groups. The Environment Agency said it has been working with Natural England to secure the white-clawed crayfish's future across the Nottinghamshire, a partnership to protect the species has been formed among various has included the Nottinghamshire Biodiversity Action Group, White Post Farm, and other environmental groups from further and volunteers are creating new safe havens, known as "ark sites", for the crayfish to relocate to, and moving numbers of them that are under threat to these protected McDaid, from the Nottinghamshire Wildlife Trust, said losing the native species would be "heart-breaking".He added: "Our waterways wouldn't be the same if they went extinct as they keep the ecosystems in our rivers healthy. If a native species like that goes, the environment around it is impacted pretty badly."We really want to prevent that, and volunteers play a vital role in helping to stop that from happening." Danielle Grieves, an officer at Natural England, said the work she has observed from volunteers in Bulwell gives her hope for the future of the added: "We are seeing fewer numbers of the North American invasive species in ponds at Bulwell Hall. "It's been so rewarding to see vulnerable, native crayfish being moved to their new homes in Nottinghamshire."By protecting the white-clawed crayfish, we're helping to preserve the biodiversity and ecological health of Nottinghamshire's waterways for future generations."

Enough doom-mongering about climate change
As a student, Johannes Ackva wore a hair shirt so itchy and uncomfortable that even Greta Thunberg might have approved. The young, idealistic German limited his use of water, stuck to a strict vegetarian diet, refused to drive and flew as little as possible. But, two decades on, Ackva, who works as a climate researcher, has changed his views considerably. He remains concerned about the environment and he still doesn't drive or eat meat. But there is cause, he believes, for optimism. Two things have changed since his hair-shirt days, he says. One is that the data looks a little less bleak than it used to. Instead of predicting that global temperatures are likely to increase by between 1.5°C (the best case) and 4.5°C (the worst), as it did for many years, the Intergovernmental Panel on Climate Change (IPCC) now says the increase will be between 2.5°C and 4°C. That 0.5°C reduction in the worst-case scenario makes a substantial difference – and itself represents a significant reduction from the 8°C rise that had, in the Noughties, been predicted by scientists such as James Lovelock for the world's temperate region. 'You have to be more optimistic than you would have been 10 years ago,' Ackva says, 'and even five years ago.' And the second thing that has changed, according to Ackva, is the rate of technological progress: 'We can see from what we've been doing with solar, or with electric cars, that we know how to fundamentally solve this problem.' The most rapid energy transition in history The price of solar energy has fallen almost at the speed of light; solar panel costs have fallen 90 per cent in the past decade alone. Renewables are helping to push coal and natural gas out of power grids. In 2009, 74 per cent of British electricity came from fossil fuels; in 2023, it was only a third. Over the same period, the share of British electricity coming from renewable sources (solar, wind etc.) has gone from two per cent to 40 per cent. In short, we are living through the most rapid energy transition in history. It is incomplete because renewables are dependent on the sun shining and the wind blowing, and because we do not have adequate battery technology to store vast amounts of electrical energy for months at a time. And, of course, it is expensive because of all the infrastructure that needs building, be it car-charging facilities, wind farms, or the apparatus that connects both of these things and more to our power grids. However, the recent progress in the energy transition is demonstrative of a truth that many environmental activists – groups like Just Stop Oil, Extinction Rebellion and the new Youth Demand – would prefer to ignore. Because, while they advocate for 'degrowth', whereby we shrink our economy and consume less in order to constrain our emissions, the innovation of recent years suggests the opposite is true: that it is investment and economic growth that will improve lives worldwide and solve the crisis. I spoke to Ackva during my research for a book about people who have dedicated their careers to saving the world from catastrophe, The Anti-Catastrophe League. He works at a non-profit organisation called Founders Pledge, where his research guides the philanthropy of entrepreneurs who want to use their wealth to address the climate crisis. And degrowth organisations are not the kind that he recommends his philanthropists support. Instead, he recommends that they fund innovation: inventions, and government action, that take the battle beyond wind farms and electric cars. 'We need to make sure that we also do it for cement, that we do it for [the manufacture of] steel, that we do it for long-range transport,' he says. 'But this is not rocket science. This is, in principle, doable.' It has been doable for longer than we might care to admit. After the Second World War, governments on either side of the Iron Curtain built nuclear power stations by the dozen. But nuclear power stations are gargantuan structures, complete with puffing chimneys atop blue-glowing reactors, and they are expensive to build. They also produce radioactive waste. This effluent is relatively unproblematic in itself, but conceptually unattractive to the public. Even more unattractive is the concept of nuclear meltdown. Chernobyl's death toll, including deaths from the explosion and acute radiation sickness within the first few months, is estimated to have been 30 to 60 people. These figures are lower than one might imagine but the victims of the Chernobyl disaster stick much more indelibly in the mind than do the abstract millions who die of fossil fuel-related air pollution each year. Despite the Chernobyl disaster, and despite smaller events at Fukushima and Three Mile Island, nuclear power is much safer than fossil fuels. The use of nuclear energy results in 99.8 per cent fewer deaths than does the use of coal; 99.7 per cent fewer than oil and 97.6 per cent fewer than gas. We can predict with some confidence that fossil fuels will be thoroughly outmoded over the course of the 21st century. It is important that governments continue to underwrite what Ackva calls 'big bets'. Fusion technology, for instance, stands a much better chance of working if, through being given public funding, it is given the gift of time. Once a technology outperforms fossil fuels, though, it will need no subsidy. We will need no carbon taxes, nor carbon credits. Thanks to far-sighted government support, the market has greedily adopted solar power and electric vehicles. Further greedy adoptions are inevitable. Bettering the miracle of fossil fuels is a lofty goal, but one that humanity is likely to meet. That still leaves a serious problem unsolved. That problem is the warming (1.17°C / 2.11°F) that has already occurred – and the warming that we are due from the greenhouse gases already in the atmosphere. Many people are trying to prevent the temperature from rising in the future; very few are trying to reverse the heating that has already occurred. But a small minority is attempting to do just that: the environmental dark wizards. Speaking with Andrew Song, he rejects the pieties of climate change. 'A lot of people were indoctrinated,' he tells me, 'including myself. I was an American boy scout, thinking: 'I just need to recycle and recycle and plant some trees, and I'm good.'' But these soothing instructions, Song came to realise, were 'all a f—ing lie!'. Telling me the story, he bursts into laughter. And he is right: recycling, in some respects, is overrated. It will not solve the climate crisis. Song has helped start several businesses in San Francisco. While enrolled in Y-Combinator, the prestigious accelerator for start-ups, Song met Luke Iseman. This was in 2016; after some false starts, Iseman said: 'Andrew, I've just learnt about stratospheric aerosol injection.' Stratospheric aerosol injection is the method by which we might be able to reduce the heat of the planet. It is achieved by launching sulphur dioxide into the stratosphere. Here sulphur dioxide reacts with other gases to form sulphate aerosols, which are fine particles. These fine particles reflect the Sun's light back into space. And the more light is reflected back into space, the less it warms the Earth. But there are downsides. The term 'uncontrolled termination' describes the scenario in which humanity starts a massive project of stratospheric aerosol injection, then abruptly stops. It is thought that this would result in ' termination shock ', whereby the temperature would swiftly rebound. Such a rebound would result in much more disruption of weather and ecology than would a more gradual rise in temperatures. And termination shock is far from the only reason to be wary of stratospheric aerosol injection. It could deplete the ozone layer. It could cause acid rain. It could have various other unintended effects. And it would not address air pollution, acidification of the oceans, and other nasty effects of the burning of fossil fuels. Instead, stratospheric aerosol injection might encourage us to stick with our bad habits. In April 2022, Iseman launched his first balloons, releasing them from his home in Baja California, Mexico. By the following February, Time magazine was calling him 'an innovator, renegade, or charlatan, depending on who you ask, but certainly the biggest climate tech trouble-maker in recent memory.' He and Song incorporated Make Sunsets, their new company, that October. Having been ticked off by the government of Mexico, they currently operate a patch of hilly Californian scrubland owned by Iseman. Journalists tagging along with Iseman and Song have witnessed a homebrew operation that resembles some of the more chaotic scenes from the TV series Breaking Bad: two rascals taking an RV to the wilderness in order to cook up something that most observers would probably call deeply irresponsible. Song, a talented marketer, tends to liken stratospheric aerosol injection to sunscreen. As he pointed out to me, humanity already puts 60 million tonnes of sulphur dioxide into the troposphere each year. Song and Iseman propose simply to put a much smaller amount of the chemical compound a little higher up. In Song's view, we have been misapplying our sunscreen. We have been 'just spraying the sunscreen lotion on our face, but with our mouths open. And since some of that is being swallowed, we're getting sick off it.' As for the ozone layer, Iseman and Song refer to evidence that its depletion will be comparatively small. Song does accept there is a risk of acid rain, but he argues that the risks of inaction are even greater. His view is that we should be less precious about geoengineering. 'We've injected two trillion tons of greenhouse gases into our atmosphere since the 1870s,' he says. 'So are we suddenly drawing a line of where we can deploy these aerosols? Literally, as we speak, we're emitting CO2, geoengineering the Earth, even just by breathing.' Global buy-in required Another difficulty, though, is that stratospheric geoengineering will require global buy-in. Or will it? Perhaps it is naive to imagine that solar geoengineering will occur after diplomatic efforts rather than before. As the climate expert Ben James writes: 'I find it impossible to imagine a UN mechanism approving something so universally contentious. Rather, someone will probably just do it.' Stratospheric aerosol injection, like nuclear fission, is a technology to which we already have access. And there are several more under development and notable for their promise. An American startup, Terraform Industries, demonstrated last year that it could produce synthetic natural gas from sunlight, water, and airborne carbon dioxide. In other words, the prototype can conjure some of the world's best-performing fuel from almost nothing. It is also possible that we will be able to take not only energy from the air, but pollution. Via carbon capture, we can remove fossil fuel-generated pollutants from the atmosphere, though we have not yet worked out how to do this in an energy-efficient manner. However, the technology I consider the most underrated involves not the air above us, but the ground below us. Today, geothermal power, which harnesses the heat of the Earth's core, constitutes a sliver of global energy production: an estimated 0.35 per cent. The figure seems even more meagre when one considers that an infinitesimal fraction of the Earth's geothermal heat, a tenth of one percent of that heat, goes the calculation, would power humanity's current outgoings for 20 million years. As it stands, we use geothermal power only where that heat happens to be closer to the surface than usual. Volcanic areas are useful in this regard. The hot springs of Bath are a less dramatic example. Elsewhere, geothermal power is harder to exploit. The idea is that you pump water down one well, bring it up via an adjacent well, and use that hot water to power turbines or heat buildings. We can drill deep enough, several kilometres down, to reach rock the temperature of a boiling kettle, or even a heated oven, but it's expensive, and can cause mild tremors. Moreover, to pay back that up-front cost, geothermal systems need to produce heat for years – which, given how hard it is to know what's going on several kilometres down, presents yet further difficulty. For that reason, this promising technology has been far less attractive an investment than drilling for fossil fuels, and has therefore remained underdeveloped. Necessity is forcing us into action. So is new technology. Commissioned by a think tank, I spent much of last year examining the performance of FORGE, the US government's geothermal field laboratory, in Utah. The lab shares its results and allows companies to visit and test their gear. Its drilling speed had increased fivefold between 2017 and 2022 and costs had fallen by as much as 50 per cent from 2022 onward. As all of FORGE's research was public, the entire geothermal industry could benefit from it. FORGE is working on 'enhanced geothermal', which employs techniques imported from the fracking industry. Likewise, the oil and gas industry has pioneered 'directional drilling', which is now allowing geothermal projects to drill not just vertically, but laterally, thus making it possible to create underground structures resembling radiators. Even more thrillingly for fanboys of geothermal power, Quaise, another company, is trying to go even deeper, which would enable it to access heat that can give water the energy density of natural gas. Quaise's method is to vapourise rock using a millimetre wave, which is something akin to a transparent laser. The company was founded by Carlos Araque, a disenchanted oil and gas engineer, advised by Paul Woskov, a fusion scientist. They must solve a litany of technical problems. But if they are successful, they could unlock a power source that would leave fossil fuels outmoded and make fusion an irrelevance. Due to advanced geothermal being in the category of those 'big bets', that would be a vindication of Ackva's approach. We failed to make the most of nuclear power; we might shy away from stratospheric aerosol injections; but to start to turn the situation around, we might need only one of those big bets to pay off.

Ushaw Historic House library open to public for one day
A library which holds historic books such as Sir Isaac Newton's Principia Mathematica will open to the public for the first time – though just for a single Historic House, near Durham, will open its 50,000-item collection to the public on 9 August as part of its first ever book library at the former Roman Catholic seminary is usually reserved for researchers, Ushaw official Sanjay Gidda forward to welcoming a wider audience, Mr Gidda said: "This is one of the most exciting cultural days Ushaw has ever hosted." As part of the day's events, the library will display its copy of the Nuremberg Chronicle illustrated encyclopaedia from book is an account of Christian history from Creation to the early about a thousand copies exist in the world today, said Mr Gidda. In addition to the 1493 edition, the library also holds a pirated copy of the book printed four years later, which was smaller and cheaper to make and of which just a few hundred still is also home to a first edition copy of Charles Darwin's On the Origin of Species, said Mr Gidda, as well as dozens of books printed during the earliest days of the printing press in Europe, known as incunabula.
