Global warming and international trade offering increasingly hospitable environment

Some are small and jumpy; others are large and intimidating – if you’re a humble housefly. Exotic spiders are flourishing in Britain as international trade offers ample opportunities for spider travel and global heating provides an increasingly hospitable climate.

A jumping spider new to science has been identified living on the University of Exeter’s Penryn campus in Cornwall. The nearest known relative of the 3-4mm-long Anasaitis milesae is found in the Caribbean, making it highly likely that this tiny species – alongside 17 other non-native jumping spider species – found its way to Britain from distant climes.

Rain in Kenya, Tanzania and Burundi kills at least 90 people and damages farmland and infrastructure

Eastern Africa has experienced heavy rain in recent weeks, with flooding in Kenya, Tanzania and Burundi. About 100,000 people have been displaced or otherwise affected in each country, with 32 reported deaths in Kenya and 58 in Tanzania, alongside damage to farmland and infrastructure.

There are also fears that large areas of standing water could give rise to outbreaks of waterborne diseases.

Soiled seas and huge shareholder dividends: where has the £64bn borrowed by firms since privatisation gone?

So that’s how they do it. I’d been wondering how, when more sewage has been entering our rivers than ever before, some of the water companies have managed to improve the ratio of the sewage they treat v the sewage that pours untreated from their storm overflows into our rivers and the sea. Now we know.

It’s called “flow trimming”. Sounds innocuous, doesn’t it? What it means is that sewage is diverted into rivers and ditches upstream of the water treatment works. By reducing the amount of sewage entering the works, the companies can claim to be dealing responsibly with a higher proportion of it.

Open letter calls for green policies that empower farmers, after months of protests jeopardise future of flagship biodiversity deal

The EU’s nature restoration law will only work if it is enacted in partnership with farmers, a group of leading scientists has said, after months of protests have pushed the proposals to the brink of collapse.

In an open letter, leading biodiversity researchers from across the world said that efforts to restore nature are vital for guaranteeing food supplies – but farmers must be empowered to help make agriculture more environmentally friendly if the measures are to succeed.

Researchers also find zebra finches 20% less likely to hatch from eggs if exposed to noise pollution

Noise pollution from traffic stunts growth in baby birds, even while inside the egg, research has found.

Unhatched birds and hatchlings that are exposed to noise from city traffic experience long-term negative effects on their health, growth and reproduction, the study found.

Shadow minister Steve Reed vows to uphold targets on biodiversity loss and protecting land and sea

Labour has pledged to halt the decline of British species and protect at least 30% of the land and sea by 2030 if it is elected.

Steve Reed, the shadow environment secretary, also vowed to set a new land use framework that would prioritise the protection of nature, and to deliver on targets to improve the UK’s environment.

Sewage pollutes our waterways, species face extinction. We must act fast to halt the decline – and we will

We must not be the last generation to have the opportunity to marvel at nature.

When I was growing up, I took for granted the excitement of climbing trees in the local woods at the end of our road, sleeping under the stars at Scout camp, and exploring the micro-worlds of seaside rockpools on holiday in Cornwall. Our children and grandchildren deserve to be astounded by the magnificence of our landscapes and coastlines, mesmerised by the beauty of a robin’s song, and to splash about in the local river.

Ali died of cancer last year. He was 21, and had to live in the choking smoke of the Rumaila oilfield

A year has passed since my beautiful boy Ali Julood died. Not a day goes by when I do not think of him smiling and playing football with his friends outside. Those days are gone. As a father, that gives me great pain.

Ali was diagnosed with leukaemia at the age of 15. The cancer caused him to drop out of school, leave his football team and spend years undergoing painful medical treatment. He died at the age of 21 on 21 April 2023.

Lack of parts and outdated laws also contributing to long repair wait times and ballooning premiums

Electric vehicles are routinely being written off after minor accidents, as a shortage of skilled mechanics and parts, as well as outdated laws, leads Australian insurers to scrap EVs prematurely instead of repairing them.

Despite the scarcity of supply that has plagued the local market in recent years, in part due to the lack of a fuel-efficiency standard, the financial reality of insuring EVs is continuing to consign them to scrap yards while inflating premiums for owners.

Proposed global treaty to curb production represents challenge to producers of fossil fuels, from which most plastics are made

The number of fossil fuel and petrochemical industry lobbyists at UN talks to agree the first global treaty to cut plastic pollution has increased by more than a third, according to an analysis.

Most plastic is made from fossil fuels, via a chemical process known as cracking, and 196 lobbyists from both industries are at the UN talks in Ottawa, Canada, where countries are attempting to come to an agreement to curb plastic production as part of a treaty to cut global plastic waste, according to analysis by the Center for International Environmental Law (Ciel).

Scheme for plastic bottles and cans put back to 2027 while environment minister says glass recycling ‘unduly’ complex

A UK deposit return scheme for recycling drinks bottles has been delayed to 2027, meaning it will not be in place until almost a decade after it was proposed.

Campaigners say the delay is a “huge disappointment”, adding they are doubly dismayed that the plan will not include glass bottles.

New EPA directive will cut pollution equivalent to the emissions of 328m cars, but industry group decries it as a ‘reckless plan’

Coal-fired power plants would be forced to capture smokestack emissions or shut down under a rule issued on Thursday by the Environmental Protection Agency (EPA).

New limits on greenhouse gas emissions from fossil fuel-fired electric plants are the Biden administration’s most ambitious effort yet to roll back planet-warming pollution from the power sector, the nation’s second-largest contributor to the climate crisis. The rules are a key part of Joe Biden’s pledge to eliminate carbon pollution from the electricity sector by 2035 and economy-wide by 2050.

Energy watchdog warns pace must accelerate to hit targets after new batteries increased capacity by 130%

The rollout of batteries across the global electricity industry more than doubled last year but will need to be six times faster if the world hopes to meet its renewable energy targets, according to the International Energy Agency (IEA).

A report from the global energy watchdog found that new batteries totalling 42 gigawatts (GW) were plugged into electricity systems around the world last year, increasing total capacity by more than 130% from the year before to 85GW.

As the climate crisis has deepened, protesters have become more confrontational – and their ambitions have grown

The head of ExxonMobil told to “eat shit” as he was about to receive an award. A US senator and coal boss called a “sick fuck”, almost sparking a brawl. Theatre shows interrupted. As the climate crisis has deepened, protests aimed at those deemed responsible are becoming starkly personal, and often confrontational.

At the vanguard of this new style of in-your-face activism is Climate Defiance, a group of just a handful of core staffers now marking its first birthday following a year of disrupting, often crudely, the usually mundane procession of talks, speeches and panels that feature Joe Biden administration officials, oil company bosses and financiers.

Authorities are rushing to save more than 150 whales from a mass stranding at a beach in Western Australia’s south-west. Four pods have spread across roughly 500 metres at Toby Inlet near Dunsborough and 26 of these have died, Parks and Wildlife Service Western Australia confirmed. Wildlife officers, marine scientists and veterinarians are on site assessing the conditions of the whales that have become stranded

Green Finance Institute report said further pollution could cut 12% off GDP by 2030s

The destruction of nature over the rest of the decade could trigger a bigger economic slump in Britain than those caused by the 2008 global financial crisis and the Covid pandemic, experts have warned.

Sounding the alarm over the rising financial cost from pollution, damage to water systems, soil erosion, and threats from disease, the report by the Green Finance Institute warned that further breakdown in the UK’s natural environment could lead to a 12% loss of gross domestic product (GDP) by the 2030s.

Finance chiefs say higher taxes for the super-rich are key to battling global inequality and climate crisis

• Billionaires should pay minimum 2% wealth tax, say G20 ministers

When the governors of the World Bank and the International Monetary Fund convened for the spring meetings last week, it was all about the really big questions. What can the international community do to accelerate decarbonisation and fight climate change? How can highly indebted countries retain fiscal space to invest in poverty eradication, social services and global public goods? What does the international community need to do to get back on track towards reaching the Sustainable Development Goals (SDGs)? How can multilateral development banks be strengthened to support these ambitions?

There is one issue that makes addressing these global challenges much harder: inequality. While the disparity between the richest and poorest countries has slightly narrowed, the gap remains alarmingly high. Moreover, in the past two decades, we have witnessed a significant increase in inequalities within most countries, with the income gap between the top 10% and the bottom 50% nearly doubling. Looking ahead, current global economic trends pose serious threats to progress towards higher equality.

Illnesses such as dengue and malaria to reach unaffected parts of northern Europe, America, Asia and Australia, conference to hear

Mosquito-borne diseases are spreading across the globe, and particularly in Europe, due to climate breakdown, an expert has said.

The insects spread illnesses such as malaria and dengue fever, the prevalences of which have hugely increased over the past 80 years as global heating has given them the warmer, more humid conditions they thrive in.

Authorities are rushing to save more than 150 whales from a mass stranding at a beach in Western Australia’s south-west. Four pods have spread across roughly 500m at Toby Inlet near Dunsborough and 26 of these have died, Parks and Wildlife Service Western Australia confirmed.

“There are 20 whales in a pod about 1.5km offshore. Another pod of about 110 animals are together closer offshore,” a spokesperson said.
