Ove Hoegh-Guldberg's pioneering research in the 1990s found increasing sea temperatures would damage the world's coral reefs, killing them faster than they could recover. Hoegh-Guldberg speaks with Guardian Australia about being labelled an alarmist while championing one of the world's richest ecosystems.Subscribe to Guardian Australia on YouTubeThis video is part of Weight of the World: a climate scientist's burden. The series features three pioneering Australian climate change scientists - Graeme Pearman, Lesley Hughes and Ove Hoegh-Guldberg. The series tells the story of how the three scientists made their discoveries, how they came under attack for their science and the personal toll it has taken on them. And importantly, how they stay hopeful.

Study's author says we need to reduce exposure in order to ensure men who want to conceive are able to without interference'Exposure to several widely used insecticides probably decreases sperm concentration and may have profound effects on male fertility, new US research finds.The George Mason University paper analyzed five decades of peer-reviewed studies to determine if organophosphates and carbamate-based pesticides exposure correlated with decreased sperm concentration.

The Eurasian eagle owl has been living in Central Park since escaping the zoo, and just returned from a Lower East Side visitIs he back?" Russell Davis exclaimed, as he spotted a group of people looking up at a tree during his afternoon bike ride. Davis stopped in his tracks, dismounted and joined the onlookers admiring a statuesque owl with piercing orange eyes and unmistakable ear tufts. New York's Central Park has experienced a homecoming of sorts, perhaps even a minor Thanksgiving miracle - the return of the beloved celebrity bird known as Flaco.Since February, the Eurasian eagle owl had been living wild after fleeing the Central Park zoo, where he had been an exhibit for 13 years, after his enclosure was vandalized.

Global fall averaged 4.2% between 2010 and 2022 but would have been far more if vehicle sizes stayed sameEmissions from the motor sector could have fallen by more than 30% between 2010 and 2022 if vehicles had stayed the same size, a report has found.Instead, the size of the average car ballooned as the trend for SUVs took off, meaning the global annual rate of energy intensity reductions - the fall in fuel used - of light-duty vehicles (LDV) averaged 4.2% between 2020 and 2022.

In 2017, 66 people died after fires ripped through eucalyptus stands around Pedrogao Grande. Restrictions on the highly flammable trees have provoked death threats, yet others feel they do not go far enoughPhotographs by Maria AbranchesThe grapevines were the first signs of life to re-emerge, Joao Duarte remembers. The green leaves appeared after months of living in a black landscape, burned by the inferno that killed two of Duarte's family. Next to return were the ferns, followed by the cork trees. Then came the eucalyptus, in greater numbers than before.I am a little afraid of the eucalyptus. I am not against them. People need money," says Duarte, a 57-year-old painter who is the gardener at the Pedrogao Grande town hall gardens in central Portugal. I live in a place surrounded by a green desert of eucalyptus. If another fire comes, it could be worse."Top: The fire, which broke out on 17 June 2017 in the Pedrogao Grande district. Above: Some of the damage caused by the fire.

Daily atmospheric carbon dioxide data from Hawaiian volcano more than double last decade's annual averageJust above this column on the weather page of the Guardian's print edition is the daily atmospheric carbon dioxide readings from Mauna Loa in Hawaii, the acid test of how the world is succeeding in combatting climate change. A week before the 28th annual meeting of the United Nations Framework Climate Change Convention opens in oil-rich Dubai, it makes depressing reading.At the time of writing it is 422.36 parts per million. That is 5.06ppm more than the same day last year. That rise in 12 months is probably the largest ever recorded - more than double the last decade's annual average. Continue reading...

Bog oak' study finds more than 400 well preserved yews, which could help solve mystery of historic rapid sea level riseThe flat landscape of the East Anglian Fens is known for its vast arable fields and absence of trees. But just over 4,000 years ago, these lowlands were dominated by dense woods of ancient yew trees.A study of hundreds of tree trunks inadvertently dug up by fenland farmers has found that this woodland abruptly disappeared 4,200 years ago, probably because a rapid rise in the North Sea flooded the low-lying region with saltwater.

Global conferences such as the upcoming Cop28 may seem like staid and ritualistic affairs. But they matterStare at a climate map of the world that we expect to inhabit 50 years from now and you see a band of extreme heat encircling the planet's midriff. Climate modelling from 2020 suggests that within half a century about 30% of the world's projected population - unless they are forced to move - will live in places with an average temperature above 29C. This is unbearably hot. Currently, no more than 1% of Earth's land surface is this hot, and those are mainly uninhabited parts of the Sahara.The scenario is as dramatic as it is because the regions of the world affected most severely by global heating - above all, sub-Saharan Africa - are those expected to experience the most rapid population growth in coming decades.

More and more enthusiasts have fallen in love with this relative of garden dwellers, and are helping ocean science while they're at itTwo years ago, Libby Keatley was diving off the coast of County Antrim in Northern Ireland when she spotted something unusual. It was a sea slug - or nudibranch - whose transparent body had orange lines running through it and twiggy projections arranged along its back. It was quite distinctive and not like anything I'd seen before," she says.Keatley called over her diving buddy, Bernard Picton, a local marine biologist and pioneer in UK sea slug studies. He scooped it up in a plastic bag and, back at his lab, confirmed it was a newly discovered species. He named it in Keatley's honour: Dendronotus keatleyae. Continue reading...

Local celebrity spent weeks outwitting animal control officers and was praised by residents of West Orange for bringing town together'Residents of West Orange, New Jersey, have been left heartbroken after a wild turkey named Turkules", whose resilient nature and ability to evade capture brought the town together", was finally snared by state officials.Turkules, who was named by a local man, first took up residence in West Orange, 25 miles west of New York City, over the summer. The bird's fearless attitude towards traffic and disregard for authority soon made him a local celebrity, and his fame only grew as Turkules spent weeks outwitting animal control officers.

Isle of May's wildlife warden calls it soul-destroying' to discover birds he ringed as chicks washing up dead on the Scottish coastFor decades, as dusk drew in every evening, up to 700 shags would fly from their foraging grounds near Fife to the Isle of May to roost for the night. Some of the birds had been doing this trip twice a day for 20 years, returning to the same cliff ledge, squabbling over who sat where.On 31 October, Mark Newell sat on the rock, waiting for their noisy return. He saw nothing. Eventually, 25 exhausted-looking birds straggled back. They did not fly off when he approached. The soundtrack of honking and bickering had stopped. Continue reading...

A slower paced life with less work and more community focus - if enough people share the dream, we can make it happenFaced with the now undeniable impacts of climate crisis created by humans, political leaders in wealthier countries incline towards one of two competing responses. They either question the urgency and feasibility of meeting net zero targets and generally procrastinate (the rightwing tendency); or they proclaim their faith in the powers of magical green technologies to protect the planet while prolonging and extending our present affluent ways of living (a position more favoured on the left and centre).Common to both approaches is a wrongheaded presumption that we can carry on growing while managing to hold off the floods and fires of growth-driven capitalism. Both also take it for granted that the consumerist lifestyle is essential to the wellbeing of rich societies and the ideal to which less developed economies should aspire. Continue reading...

Study finds impact of heat on millions of people went unrecorded, highlighting limitations many African countries faceA record-breaking heatwave in Madagascar in October would have been virtually impossible" without human-caused global heating, a study has shown.The extreme temperatures affected millions of very poor people but the damage to their lives was not recorded by officials or the media. Many governments in Africa lack the capabilities to record climate impacts. The scientists behind the report said this lack of information made implementing measures to avoid deaths very difficult.

French economist says class inequality must be at centre of climate response and calls for progressive carbon taxes Who are the polluter elite and how can we tackle carbon inequality?Questions of social and economic class must be at the centre of our response to the climate crisis, to address the huge inequalities between the carbon footprints of the rich and poor and prevent a backlash against climate policies, the economist Thomas Piketty has said.Regulations will be needed to outlaw goods and services that have unnecessarily high greenhouse gas emissions, such as private jets, outsized vehicles, and flights over short distances, he said in an interview with the Guardian.

Scientists on conservation frontlines publish concerns that the red list of threatened species is outdated and unreliableAlice Hughes found the strange reptile in March. It was hanging by its long, slender fingers from the limestone wall of a cave in northern Thailand: a grey-brown gecko she believes belongs to a species unknown to science.Hughes, a conservation biologist at the University of Hong Kong, is part of a group researching limestone systems, valuable arks of biodiversity pocked with deep caves that can shelter rare species. Many of those species are not known to science," she says. This was the group's second new discovery after a neon-green cave gecko found in Myanmar in 2017. Continue reading...

Saving the industry means saddling consumers with ever more debt. The fumes of 2007 are in the airDuring lockdown in 2020, the local council in my neighbourhood of Levenshulme - a suburb of red-brick terraces in Manchester - proposed a low-traffic neighbourhood scheme. The plan generated substantial backlash among a segment of the community, leading to all kinds of rows and questionable behaviour on Facebook and elsewhere.A central claim of the objectors was that people such as me who generally supported the measures were middle-class hippies intent on disrupting ordinary, working-class people who needed their cars in their day-to-day lives. At times, it seemed to touch on conspiracy theory. Supporters were cast as canny gentrifiers", who saw the planters being proposed to block traffic flow as an opportunity to increase the value of their properties. Continue reading...

The expensive appliances claim to eliminate kitchen food waste by turning it to instant compost. But experts are skepticalMichelle Cehn, founder of the popular Instagram account @vegan, built her reputation around her love for the planet - but food waste was something that she struggled with. I've been wanting to compost, but I've always been really overwhelmed by an outdoor compost pile," she said in a voiceover of a recent post that showed her picking fresh vegetables from the vine. And so this year I started composting indoors with the Lomi electric composter." In the short video, Cehn went on to explain how she simply dropped food scraps into the small electric bin on her countertop, pressed the button, and was left with nutrient-rich plant food" a few hours later that she could use in her garden.Lomi, the device Cehn was hyping, is just one of a new cohort of gadgets claiming they can eliminate kitchen food waste that are starting to gain traction, alongside brands like Mill, FoodCycler and Airthereal. Often marketed as electric composters", these appliances, which look a little like trash cans, dry and grind food waste into a mixture that some manufacturers claim can be used as a fertilizer and soil amendment, much like compost.

Internal emails show pressure from industry lobbyists and politicians led Trump-era agency to change position on aldicarbThe US Environmental Protection Agency (EPA) is considering approving a pesticide for use on Florida oranges and grapefruits despite the fact that agency scientists have repeatedly found the chemical does not meet safety standards designed to protect children's health, internal agency records show.EPA emails indicate how for years, agency scientists have wanted to deny new uses of aldicarb, but appear to have not done so because of persistent pressure from chemical industry lobbyists, politicians and political appointees.This story is co-published with the New Lede, a journalism project of the Environmental Working Group Continue reading...

At annual yacht show, only a handful of customers said they were troubled by vessels' disproportionate carbon footprintThe largest of the yachts in Monaco's harbour were worth more than the annual GDP of some small island states. But few of the customers touring their decks seemed to care that buying the former would help drown the latter. I don't think about this yet," said Elena Papernaya, an artist who had set her eyes on a mid-sized yacht, when asked if she worried about the damage it would do to the climate.Kasper Hojgaard, a regional manager for an industrial company who charters yachts for a few weeks each year, said he did not consider climate change at all" when doing so. His friend Lasse Jensen, a pension fund manager, nodded in agreement. We are beginning to look a bit more into it, but it's not playing a role." Continue reading...
