World faces new danger of ‘economic denial’ in climate fight, Cop30 head says

Exclusive: André Corrêa do Lago says ‘answers have to come from the economy’ as climate policies trigger populist-fuelled backlash

The world is facing a new form of climate denial – not the dismissal of climate science, but a concerted attack on the idea that the economy can be reorganised to fight the crisis, the president of global climate talks has warned.

André Corrêa do Lago, the veteran Brazilian diplomat who will direct this year’s UN summit, Cop30, believes his biggest job will be to counter the attempt from some vested interests to prevent climate policies aimed at shifting the global economy to a low-carbon footing.

Brazil activists decry green rollbacks as senate passes ‘devastation bill’

Legislation would dismantle regulations in farming, mining and energy, increasing risk of widespread destruction

Environmental activists in Brazil have decried a dramatic rollback of environmental safeguards after the senate approved a bill that would dismantle licensing processes and increase the risk of widespread destruction.

The upper house passed the so-called “devastation bill” with 54 votes to 13 late on Wednesday, paving the way for projects ranging from mining and infrastructure to energy and farming to receive regulatory approval with little to no environmental oversight.

Watchdog urges Scotland to take action after repeatedly missing climate targets

Climate Change Committee says original goal of a 75% emissions cut by 2030 will now be delayed by up to six years

The UK’s climate watchdog has warned that Scotland needs to take “immediate action at pace and scale” to cut its emissions after ministers axed a series of policy pledges.

The Climate Change Committee (CCC), an official advisory body, said ministers in Edinburgh needed to take urgent action to curb emissions from buildings and transport to cut Scotland’s overall emissions to nearly zero by 2045.

Abandoned a target to cut car miles by 20% by 2030.

Dropped a pledge to rapidly decarbonise homes by mandating low-carbon heating systems.

Cut funding for tree planting.

Missed targets to restore degraded peatland.

Ignored calls for a plan to cut meat and dairy consumption, and failed to use their powers to tax air travel more heavily.

‘A horror movie’: sharks and octopuses among 200 species killed by toxic algae off South Australia

Karenia mikimotoi algae can suffocate fish, cause haemorrhaging and act as a neurotoxin, one expert says

More than 200 marine species, including deepwater sharks, leafy sea dragons and octopuses, have been killed by a toxic algal bloom that has been affecting South Australia’s coastline since March.

Nearly half (47%) of the dead species were ray-finned fish and a quarter (26%) were sharks and rays, according to OzFish analysis of 1,400 citizen scientist reports.

Climate crisis threatens the banana, the world’s most popular fruit, research shows

Fourth most important food crop in peril as Latin America and Caribbean suffer from slow-onset climate disaster

The climate crisis is threatening the future of the world’s most popular fruit, as almost two-thirds of banana-growing areas in Latin America and the Caribbean may no longer be suitable for growing the fruit by 2080, new research has found.

Rising temperatures, extreme weather and climate-related pests are pummeling banana-growing countries such as Guatemala, Costa Rica and Colombia, reducing yields and devastating rural communities across the region, according to Christian Aid’s new report, Going Bananas: How Climate Change Threatens the World’s Favourite Fruit.

Noaa to stop tracking cost of climate crisis-fueled disasters: ‘Major loss’

US agency will no longer update major weather database in latest showing of Trump’s influence on climate resources

The National Oceanic and Atmospheric Administration (Noaa) will no longer track the cost of climate crisis-fueled weather disasters, including floods, heatwaves, wildfires and more. It is the latest example of changes to the agency and the Trump administration limiting federal government resources on climate change.

Noaa falls under the US Department of Commerce and is tasked with daily weather forecasts, severe storm warnings and climate monitoring. It is also parent to the National Weather Service.

April storms that killed 24 in US made more severe by burning fossil fuels – study

Study finds human-caused climate change made four-day rainfall across central Mississippi valley 40% more likely

The four-day historic storm that caused death and destruction across the central Mississippi valley in early April was made significantly more likely and more severe by burning fossil fuels, rapid analysis by a coalition of leading climate scientists has found.

Record quantities of rain were dumped across eight southern and midwestern states between 3 and 6 April, causing widespread catastrophic flooding that killed at least 15 people, inundated crops, wrecked homes, swept away vehicles and caused power outages for hundreds of thousands of households.

Scorpions ‘taking over’ Brazilian cities with reported stings rising 250%

Fast and unplanned growth of cities providing ideal conditions for the creatures to thrive, say researchers

Scorpions are “taking over” Brazilian cities, researchers have warned in a paper that said rapid urbanisation and climate breakdown were driving an increase in the number of people being stung.

More than 1.1m stings were reported between 2014 and 2023, according to data from the Brazilian notifiable diseases information system. There was a 250% increase in reports of stings from 2014 to 2023, according to research published in the journal Frontiers in Public Health.

Real-world geoengineering experiments revealed by UK agency

Trials will test ways to block sunlight and slow climate crisis that threatens to trigger catastrophic tipping points

Real-world geoengineering experiments spanning the globe from the Arctic to the Great Barrier Reef are being funded by the UK government. They will test sun-reflecting particles in the stratosphere, brightening reflective clouds using sprays of seawater and pumping water on to sea ice to thicken it.

Getting this “critical missing scientific data” is vital with the Earth nearing several catastrophic climate tipping points, said the Advanced Research and Invention Agency (Aria), the government agency backing the plan. If demonstrated to be safe, geoengineering could temporarily cool the planet and give more time to tackle the root cause of the climate crisis: the burning of fossil fuels.

Weather tracker: State of emergency as high winds and floods hit New Zealand

Met Service issues red warning amid deepening low pressure, while Europe experiences above average temperatures

Strong winds and flooding spread across New Zealand last week, with a state of emergency declared in Christchurch, after the country was battered by a destructive area of low pressure. A red warning, the highest warning level, was issued by the MetService (the national meteorological service).

The area of low pressure quickly deepened in the Tasman Sea off the west coast of New Zealand and travelled eastwards, with the centre of low pressure moving across the northern island and creating very strong winds, particularly through the Cook Strait, the body of water that separates the two islands. The wind direction was a south-easterly to southerly, which caused the winds to strengthen as they were funnelled between the islands.
