Conservation Volunteering at Prawle Point with Buglife

The NHBS team are passionate about nature and conservation, and to help them to get involved with local volunteer schemes, NHBS encourages colleagues to apply for up to three paid days each year to volunteer with a conservation project or organisation of their choice. Catherine Mitson, Assistant Editor for British Wildlife and Conservation Land Management, tells us about her time volunteering with Buglife and the bee species she is surveying.

The Long-horned Bee Eucera longicornis truly lives up to its name. The males sport bizarrely long antennae, and this in combination with their large size makes them instantly recognisable. Female Long-horned Bees, however, lack these oversized antennae and are more robust compared to the males, and can sometimes be confused with Anthophora (flower bees) species. Although the Long-horned Bee is a type of solitary bee and each female will dig her own nest hole, they tend to nest in aggregations in a variety of habitats, such as woodland rides and clearings, brownfield sites and coastal meadows. Here, however, we are focused on the south-facing soft cliffs along the South Devon coastline.

Prawle Point SSSI is a fantastic site for invertebrates, including the Long-horned Bee which can be found nesting in the cliff face or foraging on plants such as clovers, Bird’s-foot-trefoil and Narrow-leaved Everlasting-pea along the cliff top. What makes Prawle Point even more special is that it is the only site in the UK where the Long-horned Bee’s cuckoo, the Six-banded Nomad Bee Nomada sexfasciata, is known to be found. Like the bird, cuckoo bees lay their eggs in the nest of another bee, the host, and once hatched the larvae will eat the food stores that had been gathered by the host for its own larvae.

The Six-banded Nomad Bee is arguably the UK’s rarest bee, and relies on a healthy, viable population of its host. Sadly, due to the loss of flower-rich grassland, the Long-horned Bee has declined dramatically; once found in most southern English counties, its range is now restricted to the south coast of England and Wales with a few scattered inland sites. But a new project is hoping to turn the tide for the Long-horned Bee, the Six-banded Nomad Bee and many other rare invertebrates along the South Devon coast.

Life on the Edge

Life on the Edge, funded by the National Lottery Heritage Fund, is an exciting new partnership with South Devon Area of Outstanding Natural Beauty, Buglife, National Trust, Torbay Coast and Countryside Trust, and the South West Coast Path Association. Focused on the South Devon coast between Berry Head and Wembury, Life on the Edge is aiming to restore viable populations of some the UK’s rarest invertebrates, including the Six-Banded Nomad Bee, by expanding and reconnecting the vital coastal habitats on which these species depend. There are 30 invertebrate species that this project will support, such as the Moon Spider, Great Green Bush-cricket, Mediterranean Oil Beetle and the Devon Red-legged Robberfly, but of course, by improving and expanding the habitats used by these species, a plethora of wildlife will benefit.

Buglife will be working alongside its project partners to create opportunities for local communities, landowners, parish councils and schools to get involved via volunteer days, habitat management and creation workshops, wildlife gardening and species monitoring. The project is currently in its development phase and is focused on public consultation and species and habitat monitoring – this work will help to secure funding for the next phase of the project.

NHBS conservation volunteering day

My role as a volunteer is to undertake surveys throughout the flight season of both the Long-horned Bee and its cuckoo between May and July and record the number of individuals seen along this stretch of coast, with a particular focus on known nest aggregation sites and the coastal path between Gara Rock and Mattiscombe Sands. The survey consists of slowly walking along the coastal path, stopping to count Long-horned Bees when I see them. I record the number of males and females, the location/grid reference, and any extra information that may be useful, such as the plants that they are feeding on.

It was wonderful to see so many Long-horned Bees foraging along the cliff top throughout the day. As mentioned above, they tend to favour plants such as Bird’s-foot-trefoil, clovers, Narrow-leaved Everlasting-pea, brambles and Kidney Vetch, and there are sections of the coastal path where these can be found in abundance. Unfortunately, these plentiful patches are in short supply, and Buglife hopes to identify the key areas for habitat enhancement to support the population of Long-horned Bees, which will in turn benefit the Six-banded Nomad Bee.

The highlight of the day was watching one nest aggregation in particular, a site that we have become quite familiar with over the years. It is always a bustling hub of activity and is primarily where the Six-banded Nomad Bee has been recorded in the past. Female Long-horned Bees were repeatedly flitting in and out of the nest entrance holes, with the occasional male patrolling the nest entrances in search of a mate. Sadly, I did not see the Six-banded Nomad Bees this time but was pleased to count a total of 75 Long-horned Bee sightings throughout the day.

I have been involved in monitoring this site since 2017 and so it was wonderful to have the support of NHBS to spend some time at Prawle Point to contribute to this year’s records. It is vital that monitoring along this stretch of coastline continues, especially as our records of the Six-banded Nomad Bee are so few.

This Week in Biodiversity News – 31st July 2023

Science and Research

An Oxford University study has revealed that eating less meat would be like taking 8 million cars off the road. Low meat-eaters were found to produce 5.37kg of greenhouse gases per day, almost half of the 10.24kg that big meat-eaters produced. Fish-eaters and vegetarians produce 4.74kg and 4.16kg respectively while vegans produce only 2.47kg. The results, which also detail land use, water use and biodiversity impacts, show the benefits that a low-meat diet can have for the planet. It has long been established that meat production has a bigger carbon footprint than plant production, but the level of detail seen in the study is unprecedented according to scientists.

Climate Crisis

Thousands of people have been evacuated from Greece following intense wildfires on the island of Rhodes. Strong winds blew fires that had been raging in the island’s interior towards the coast threatening hotels and tourist areas. Meteorologists have warned that temperatures are forecast to reach a 50-year high for the month of July in Greece, with extremes of up to 45°C. Brutally high temperatures have been seen across southern Europe this July, including Italy where most major cities have been put on red heat alert.

The former head of the UN climate body the IPCC has warned that the world will miss the 1.5°C warming limit target. Leading British climate scientist Professor Sir Bob Watson told the BBC that he is “pessimistic” about even achieving a 2°C limit. The 1.5°C limit was agreed at the UN conference in Paris in 2015 and has become a focus for global efforts to tackle climate change. The IPCC has said that failing to meet the 1.5°C threshold could expose millions more people to losing their homes to rising sea levels, increased water insecurity, and devastating coral reef biodiversity losses. To meet the 1.5°C or 2°C targets, greenhouse gases need to be reduced; however, emissions are continuing to rise.

Extinction Risk

The world’s most endangered large whale is closer to extinction than experts thought. In a blow for whale biodiversity, only a few hundred North Atlantic right whales are estimated to remain in the world’s oceans according to the NOAA. With only 70 reproductively active females remaining, the species is fast approaching extinction. Unexpectedly high mortality since 2017, in large part from human activity, has resulted in a catastrophic decline in right whale numbers. Research by the New England Aquarium has suggested that vessel strikes and fishing gear entanglements are the greatest threat to the 100 ton marine mammal; 86% of identified whales were found to have been caught in fishing gear.

Golden paintbrush has been removed from the endangered species list following recovery efforts. The US Fish and Wildlife Service has taken the flowery yellow plant off the endangered species list after more than 25 years. The flower can be found in the Pacific Northwest where its native range stretches from Oregon to southwestern British Columbia. Golden paintbrush numbers shrunk significantly due to pressure from invasive species, recreational picking and fire suppression. However, following replanting efforts, the number of sites the species is present in has increased from 10 to 48. In a boost for local biodiversity, the plant’s recovery could also benefit associated species such as the Taylor’s checkerspot butterfly and Mazama pocket gopher.

Conservation

The south of England saw its first white-tailed eagle birth in 240 years. White-tailed eagles were once widespread across England but became extinct due to human persecution. The birds, also known as sea eagles, are Britain’s largest birds of prey with a wingspan approaching 2.5 meters (8.2 ft). A Forestry England and Roy Dennis Wildlife Foundation project re-introduced the birds to the Isle of Wight from northern Scotland in 2020. Licensed ornithologists have ringed the chick and fitted it with a tracking device.

In a similarly successful re-introduction programme, pine martens saw a third successful breeding year in the Forest of Dean. The initiative led by the Gloucester Wildlife Trust introduced 35 individuals to the forest between 2019 and 2021 with numbers now swelling to close to 60. Pine martin populations at one point were pushed to the remote corners of Scotland due to hunting and deforestation; however, recent recovery programmes in Wales and England have seen the elusive mammal returning from the brink of extinction south of the Scottish border.

Policy

G20 countries failed to reach an agreement on cutting fossil fuels following recent meetings in India. The summit saw disagreements over a goal of tripling renewable energy capacity by 2030 which Saudi Arabia, Russia, China, South Africa and Indonesia are known to oppose. G20 members account for more than three-quarters of global emissions and so efforts by the group to reduce carbon emissions are essential if global warming targets are to be met.

New Discoveries

A study has found that post-menopause orca mothers protect their sons from other orcas. Using data from the Center for Whale Research’s annual photographic census, researchers found that if a male orca’s mother was still alive and no longer reproducing, the male would have reduced scarring when compared to peers with a mother still reproducing or without a living mother. Females can live up to 90 years in the wild with an average of 22 years after menopause. Previous studies have shown that post-menopause mothers also aid their families by sharing food.

Author interview with Fiona Mathews and Tim Kendall: Black Ops & Beaver Bombing

Black Ops & Beaver Bombing: Adventures with Britain’s Wild Mammals is a captivating and entertaining deep dive into many of the mammals of Britain. Fiona Mathews and Tim Kendall explore mines inhabited by great horseshoe bats, go on overnight stakeouts in search of pine martens and travel from Scotland to the Isles of Scilly in search of their elusive subjects. This book puts animals at the heart of the story, revelling in their peculiarities and exploring the threats to their survival and the struggles that plague their conservation in Britain. The depth of knowledge, witty commentary and obvious enthusiam creates a beautifully written book that is difficult to put down.

Each chapter focuses on a different UK mammal, from wild boars and beavers to red squirrels and grey seals. Fiona and Tim explore the history, ecology and current conservation of these species, focusing on what is threatening them and what should or is being done to protect them. They do not shy away from giving criticism and sharing their frustration when the attitudes of policy makers stand against environmental protection and restoration. In search of answers to the problems that beset our wildlife, the authors reveal the wonder of creatures that are worth fighting for.

Fiona Mathews is a professor of environmental biology at the University of Sussex and the founding chair of Mammal Conservation Europe. Tim Kendall is a professor of English Literature at the University of Exeter and edited Britain’s Mammals 2018. They have kindly agreed to an extended interview with us, where we discuss the role of public education in conservation projects, how climate change may be impacting population recruitment in bats and seals, whether there is hope for the reintroduction of top mammalian predators, and much much more.

Could you tell us how you both became interested in mammals and what inspired you to create this deep dive into the mammals of Britain?

Tim: I grew up right next door to Devonport Dockyard in Plymouth. I was obsessed with spotting mammals as a child, but the only ones I ever saw were grey squirrels. When I was 8 or 9, I wrote a poem for school about seeing a badger, describing the joy and excitement I felt. It was all made up: I didn’t see a live badger until after I left for university. Luckily, I had the good sense to marry a mammal biologist and carry out fieldwork with her, which means that I’ve now seen all but three of our native mammal species.

Fiona: I’ve been interested in mammals for as long as I can remember, but I decided it should become my career after I went on my first bat walk. Black Ops and Beaver Bombing was partly inspired by my work reviewing the population status of Britain’s mammals and drawing up the Red List with the Mammal Society.

The preface, I-Spy, makes an interesting point about the interconnectedness of species as well as the focus of conservation: “If you want to save the barn owl, start by saving the field vole”. Do you believe the focus on ‘charismatic’ species, which are often higher up in the food chain, more often aids the conservation of prey species (such as by increasing or improving habitats) or harms these species by increasing the population of their predators? Should more conservation projects take a more ‘grassroots’ focus, by helping species lower down on the food chain?

We ignore the small species at our peril, and the fact that they’re almost all in decline is deeply worrying. Of course, wolves and wild cats grab the headlines, but if we don’t pay attention to the bioabundant species, everything across the food web is affected. We talk a lot in the book about the Scilly shrew, and if we’d thought anyone would read it, we’d have included a chapter on field voles.

In Chapter 3 ‘On the Trail of the Lonesome Pine Marten’, you discuss the extensive work done to win over the local people before the ‘recovery’ project began. Do you believe the public will become more and more open to these types of projects or will public education always need to play such an extensive role?

The general public is already becoming more welcoming, but the people who control landscapes are a small subset of the population, and they often have their own priorities that they believe (rightly or wrongly) will be damaged by reintroduction and recovery projects. One of the unfortunate things about rewilding is that it’s becoming as divisive as Brexit. We should all be working together to reverse the biodiversity crisis.

Wild mammals only make up between 2–4% of the world’s mammal biomass, decreasing by more than 85% since the rise of humans. In contrast, livestock makes up more than 63% of mammal biomass. How has this drop in wild mammal biomass impacted ecosystems and do you think we’ll be able to repair this?

High intensity livestock production is undoubtedly a massive contributor to biodiversity loss, but we mustn’t perceive farmers as the enemy. We need good farmers producing good food and getting rewarded for sustainable and wildlife-friendly production. Progress towards reforming agricultural subsidies has moved at glacial speed. Our government, like most across the globe, is much too heavily influenced by the lobbying of large agribusinesses which want to preserve the status quo.

In Chapter 5 ‘Hanging Out with Greater Horseshoe Bats’, you mention that Fiona is working on a long-term plan to re-establish the British population of the greater mouse-eared bat. Could you tell us a little bit more about how this process would work?

Fiona: Historically, the greater mouse-eared bat has been found in Dorset and Sussex, but with climate change we would expect its range to shift northwards. There are large and thriving colonies in Brittany and Normandy at the moment. We have to work out whether they will arrive in England under their own steam, or whether we need to give them a helping hand. Translocating bats isn’t easy. I’ve set up a working group at Eurobats to bring together experts looking at the best way forward.

You mention that the greater horseshoe bat population has stabilised and is now increasing in Britain. Why do you think this is happening?

The species is struggling across mainland Europe but it has responded well to a series of mild winters in England and Wales. Organisations like the Vincent Wildlife Trust have done a fantastic job to protect and improve roosts. We should remember, though, that greater horseshoes once had a range that extended to the east of England, and it’s estimated that there was a population of 300,000 at the end of the nineteenth century. The current population is about 4% of that total, which is a remarkable recovery from their lowest levels, but we need to be aware of shifting baseline syndrome before we celebrate the good news too enthusiastically.

Chapter 5 also mentions a new system for monitoring bats, which monitors the flight paths using radio receivers. Do you think that, by highlighting important flight paths, this system will be able to be used to reduce the impacts of new developments?

Although legislative protection means that we now know a lot about bat roosts in buildings, there’s not much point protecting a roost if the animals lack places to forage or mate. New techniques such as static radio tracking allow us to identify important sites and protect them for the future.

As cool weather in spring can have an impact on the growth and development of young bats, has climate change impacted juvenile survival rates and population recruitment?

We know that baby bats grow less well, with short- and long-term consequences, when weather conditions are poor in the breeding season. We would expect to see negative effects from climate change, and this is something we are currently looking at in a European-wide project. The challenge is that few researchers have datasets that span at least 20 years, which is the timeframe you need for analysing these long-term trends. So we’re also conducting other research on shorter timescales to assess whether mother bats are moving around their roosts to select different temperatures.

Chapter 6 ‘Tiggywinkle Goes Rogue’, mentions how ‘tidiness’ harms biodiversity. Do you think the growth in recent campaigns such as No Mow May will help to reduce society’s obsession with garden ‘neatness’?

Yes! It also requires us to hassle our local councils until we outnumber those strange people who complain about overgrown verges. Councils will take the path of least resistance, which should be to do as little ‘tidying’ as possible.

A common threat for several of the species you cover in Black Ops & Beaver Bombing is light pollution. Is there momentum at the moment that would see light pollution effectively combated in the coming years?

No, and the problem is worsened by the fact that lighting is getting cheaper and more intense. It’s frustrating because light is one of the few pollutants that simply disappears as soon as you flick a switch.

In chapter 7, ‘Who Cares What Colour the Squirrels Are?’, you mention that certain conservation strategies, such as the culling of grey squirrels to protect red squirrels, are unlikely to receive funding due to fears of adverse publicity. How much do you think conservation strategies are affected by how palatable they are to the public? Do you think this impacts the effectiveness of some conservation projects?

The biggest issue is the insatiable appetite for novelty over longevity. Nobody wants to fund routine maintenance. You may get grant money to reintroduce water voles, but will you still be funded to cull American mink a decade later?

As storms often lead to the deaths of many seal pups, will the increased occurrence of extreme weather due to climate change have a significant effect on population recruitment for seals on our shores?

We don’t know. In our seal chapter, we call the recovery of grey seals the great mammal conservation story of the twentieth century. Their numbers increased from about 500 during the First World War to well over 100,000, which makes up around 40% of the global population for the species. Storms and tidal surges can wipe out entire colonies of pups in any given season, but thankfully so far that doesn’t seem to have dented their population growth. Shout out to the amazing volunteers who rescue and raise pups for 6 months before they’re strong enough to be released!

The government recently released England’s first Marine and Coastal Wildlife Code, do you think this guidance will significantly help to protect wildlife such as grey and harbour seals from the impacts of visitors?

Yes. It was long overdue, and it’s vital. Some people will remember seeing the footage of a runner deliberately chasing a colony of seals into the sea in Yorkshire. If that happens to a moulting seal or a pup, they can die. We’re all tempted to take selfies next to wildlife, but it’s rarely a good idea.

This book ends by asking why Britain cannot seem to accept mammalian predators in the way that European countries have. Do you think there is hope for change in attitudes that could see the re-introduction of species such as lynx, wolves and bears within the coming decades?

We end the book in the Abruzzo National Park, 90 minutes drive from Rome, where there are now about 11 active wolf packs and 50 bears. The Cairngorms is ten times bigger, and has roughly the same human population. So much for the argument that we’re a crowded island! So we could and should reintroduce these apex predators, but we have to deal with misinformation from (for example) the current President of the National Farmers’ Union, who claims that lynx would pose a threat to ramblers. No wild lynx has ever attacked a human. Cattle, on the other hand, kill 8-10 people a year in Britain.

Do you have any future plans that you could tell us about?

We’ve just started a podcast, ‘Mammals R Us’ (https://rss.com/podcasts/mammalsrus/). We have very different working habits, so our big question is: can we finish another book without getting divorced?

Black Ops & Beaver Bombing by Fiona Mathews and Tim Kendall was published by Oneworld Publications in April 2023 and is available from nhbs.com.

Author interview with Lee Raye: The Atlas of Early Modern Wildlife

The Atlas of Early Modern Wildlife is a ground-breaking volume compiling the observations of early modern amateur naturalists, travellers and local historians for the first time. Drawing on over 10,000 records, this book looks at the early modern state of wildlife in Britain and Ireland, the era before climate change, before the intensification of agriculture, before even the Industrial Revolution. The book presents maps and notes on the former distribution of 153 species, providing a new baseline against which to discuss subsequent declines and extinctions, expansions and introductions. This remarkable resource will be of great value to conservationists, archaeologists, historians and anyone with an interest in the natural heritage of Britain and Ireland.

Lee Raye is an associate lecturer at the Open University and a Fellow of the Linnaean Society, specialising in the history of wild animals and plants in pre-industrial Britan and Ireland. We were lucky enough to have the opportunity to speak with them about what inspired them to write this atlas, what the most difficult aspect of creating this book was, what their future plans were and much more.

What inspired you to write this atlas?

Several years ago I worked for the RSPB. I went on a weekend induction to The Lodge in Sandy, Bedfordshire, and had a walk around with the reserve archaeologist. He explained that, although it was simple enough to know which animals had declined and gone extinct in the historical period, there was a lack of clarity about how and when this happened. I realised that I already had some of the answers he needed. Around that same time, as a research project, I was translating and analysing the records of wild animals and plants from a single 17th-century natural history book, Robert Sibbald’s Scotia Illustrata (1684). That source is really valuable because it was contributed to by so many people and contains so many important records. For example, there are records of the Great Auk, the Bustard and the Angel Shark amongst the animals and Darnel, Shepherd’s Needle, and Greater Water-parsnip amongst the plants. While doing this project, I started making a list of other comparable texts from the same time period, and to my surprise I realised there was a whole understudied genre of them! I realised that if I combined all of these sources together I could give a decent estimate of the distribution of species in the 16th-18th centuries.

Do you think it’s possible for us to restore our wildlife to the condition it was in early modern Britain or has our landscape changed too drastically?

When we are doing conservation work it’s really important that we have a strong baseline to work against, otherwise we don’t know when we are restoring biodiversity and when we are just adding species to an environment. I think the early modern period is a good choice of baseline for two reasons. First, it comes before some of the most alarming declines in biodiversity which followed trends like the industrial revolution, the 20th century agricultural revolution, and the gamekeeper culls of raptors and mammalian predators of the nineteenth and early 20th century. But it was still a period when all of Britain and Ireland was managed for human needs, including some big cities. Secondly, there are a lot of sources available from the time period, so the Atlas of Early Modern Wildlife could reconstruct the fauna found at the time. But we are never going to be able to perfectly return to that baseline. The islands of Britain and Ireland are even more intensively managed and exploited now, and we need to keep that up to provide for the human population. The early modern period was also a time when there was a temporary climate change, the Little Ice Age, which meant that the so-called ‘northern species’ were doing really well, and the ‘southern species’ had a more restricted range. Modern global heating is going to become much more severe than the Little Ice Age was, and is likely to magnify the differences so that Britain and Ireland in the 21st century is going to have significant differences in its flora and fauna to the 17th century, no matter what we do.

The distribution trend for the majority of species mentioned in this book was either uncertain or unchanged, compared to 24 increases and 26 decreases. Did this surprise you?

I knew that there would be lots of uncertainty in the data from the time period, but I was a bit surprised that so few species showed a decline in distribution. We know that we are in a biodiversity crisis now, but the declines in abundance we are currently facing are going to take some time to result in declines in distribution at a regional level, which is the rather crude metric I was able to track in the Atlas of Early Modern Wildlife. It’s also true that there have been official and unofficial reintroductions in the modern period, which have restored species like Beaver, Otter and Greylag Goose across much of their early modern range, meaning that comparing early modern and present distribution hides what happened to these species in between.

You mention that there was a bias towards recording exploitable species in the early modern period and a bias towards recording birds now. Did this affect which species you were able to include in this book?

Yes, with the exception of a few species of conservation concern, I included only the best-recorded species in my Atlas of Early Modern Wildlife. That means that there is a bias towards certain groups of species. For example, I was able to map the past distribution of 18 freshwater fishes but only five small songbirds. Don’t ask me about the distribution of the Sparrow or the Great Tit in the early modern period, because my sources don’t offer much data about them!

What was the most difficult aspect of creating this book?

The most complicated part of the Atlas of Early Modern Wildlife has been trying to solve the recorder-effort problem. I needed to be able to tell when species were not recorded because they were absent (like the Wolf, which seems to have been extinct in England and Wales already by this time period), and when animals were not recorded simply because not enough effort had been put into recording them (like those Sparrows and Great Tits which no-one really cared about). My solution was to statistically compare how many records I had for each species from different regions of Britain and Ireland with a figure of how well-recorded each different region was in the early modern period. I also used some habitat suitability modelling to try and establish patterns behind absences, but this has been complicated, speculative work!

Do you have any future plans that you can tell us about?

I think I could take this project further in the future. It should be possible to map the distribution of wild plants 250-500 years ago, or to join up the distribution of Britain and Ireland’s wildlife with the distribution of wildlife in other parts of Europe from the same time period. But I also want to work a bit more on poetry from the early modern period. There are a few very strange poems written c.1580-1650 that protest environmental destruction and are told from the perspective of animals which I think deserve to be much more widely known.

The Atlas of Early Modern Wildlife by Lee Raye is due to be published by Pelagic Publishing in July 2023 and is available for pre-order from nhbs.com.

This Week in Biodiversity News – 17th July 2023

Science and research

Dutch scientists have revealed that corvids are using anti-bird spikes to build their nests. Anti-bird spikes are often attached to building ledges to prevent birds from nesting, and this discovery was prompted when nests constructed almost entirely from the sharp metal objects were found in Rotterdam and Antwerp. It has been suggested that the spikes may help protect their nests and could even be used as a display to impress potential mates.

Salinity changes are threatening marine ecosystems, according to researchers at the University of North Florida. Changes in salt content can occur due to land use and climate change and are expected to intensify with warming oceans. Vital estuarine and coastal zones could quickly face ecosystem collapse as groups such as corals, plankton and seagrass are affected by the changes.

Climate crisis

Global average temperatures reached a new high for the third time in a week at the start of July. A record of 17.01°C early in the week was broken twice more with average temperatures reaching 17.23°C on the Thursday. While unofficial, the record points a concerning trend in recent decades of higher year-on-year global temperatures. Scientists have attributed the cause of the unprecedented temperatures to a combination of human-induced global warming and the El Niño climate pattern.

The global shipping industry has agreed to a goal of net-zero by 2050. Industry voices and small island nations have largely welcomed the deal, but it has provoked fury among environmental groups who believe the plan will do little to keep temperatures below the 1.5°C threshold set out as part of the Paris climate agreement in 2015. Shipping is responsible for around 3% of CO₂emissions and campaigners are warning that emissions targets set out in plan will see the shipping industry exhaust its carbon budget by 2032.

Severe flooding in Spain’s north-eastern city of Zaragoza swept away cars following storms and torrential downpours in early July. Video footage shows people desperately clinging to the top of cars and climbing trees while awaiting rescue by the authorities. The incident follows a worrying trend of extreme flooding seen across the world this summer.
