Research on events in Hawaii suggests climate crisis could increase eruptions around world
The spectacular eruptions of the Kīlauea volcano in Hawaii in 2018 were triggered by extreme rainfall in the preceding months, research suggests.
Scientists say the finding raises the possibility that climate breakdown, which is causing more extreme weather, could lead to an increase in eruptions around the world.

Europe had its hottest year on record last year, new data has confirmed, with periods of exceptional heat last February, June and July, and one of the wettest Novembers on record.
Previous records were broken by only a small margin, but the findings confirmed that 11 out of the 12 warmest years in Europe have occurred in the past two decades, according to the European State of the Climate 2019 report, published on Wednesday.

The warning from the World Food Programme (WFP) that an extra 265 million people could be pushed into acute food insecurity by Covid-19, almost doubling last year’s total, is based on a complex combination of factors.
WFP’s latest warning underlines the increasing concern among experts in the field that for many the biggest impact will not be the disease, but the hunger hanging off its coat tails.

The loss of summer sea ice in the Arctic is now very likely before 2050, new research shows, even if the carbon emissions driving the climate crisis are cut rapidly.
The result has alarmed scientists but they said slashing greenhouse gases remained vital as this would determine whether Arctic summer ice vanished permanently or could recover over time. If emissions remain very high, there is a risk the Arctic could be ice-free even in the dark, cold winter months, a possibility described as “catastrophic”.
Continue reading...A 96% drop in passenger numbers because of coronavirus restrictions has not been matched by cuts in flights
The coronavirus outbreak has provoked a string of unsettling sights, such as the sudden widespread use of masks, shuttered businesses and deserted streets. Another unusual phenomenon is also playing out in the skies – near-empty airplanes flying through the air.
Widespread travel restrictions around the world have slashed demand for air travel, with more than eight in 10 flights canceled. But there is a disparity in the US – while the Transportation Security Administration (TSA) has reported a 96% slump in passenger volume, to a level not seen since 1954, this hasn’t been matched by the number of flights being scrapped.

Scientists have carried out a trial of prototype cloud brightening equipment on the Great Barrier Reef they hope could be scaled up to shade and cool corals and protect them from bleaching caused by rising global temperatures.
The experiment used a modified turbine with 100 high-pressure nozzles to spray trillions of nano-sized ocean salt crystals into the air from the back of a barge.

The retreat of a Norwegian mountain ice patch, which is melting because of climate change, has revealed a lost Viking-era mountain pass scattered with “spectacular” and perfectly preserved artefacts that had been dropped by the side of the road.
The pass, at Lendbreen in Norway’s mountainous central region, first came to the attention of local archaeologists in 2011, after a woollen tunic was discovered that was later dated to the third or fourth century AD. The ice has retreated significantly in the years since, exposing a wealth of artefacts including knitted mittens, leather shoes and arrows still with their feathers attached.

Americans with lower incomes and less education were more like to say the spread of infectious disease was a major threat to the US, according to a Pew Research Center survey released Monday.
Nearly all US adults said the spread of infectious disease is a threat to the country, but people who made less than $50,000 per year were 10 percentage points more concerned about the threat posed by infectious disease than those with higher incomes in a survey conducted in March.

Scientists have shown to be true what JRR Tolkien only imagined in the Lord of the Rings: giant, slow-reproducing trees play an outsized role in the growth and health of old forests.
In the 1930s, the writer gave his towering trees the name Ents. Today, a paper in the journal Science says these “long-lived pioneers” contribute more than previously believed to carbon sequestration and biomass increase.

The long, black hem of Ibado Mohammed Abdulle’s diya drags in the sand, creating mini tornadoes of dust under her sandals. At a circular fence of waist-high thorny bushes, she knocks on the metal sheet serving as a makeshift door. A woman’s face, partially hidden by a bright green hijab, appears. “Salaam Alaikum,” Abdulle says, “peace be upon you.”
Holding up a hand to the armed guards tasked with accompanying the visiting charity staff following her around the displacement camp, she instructs them to stay outside.
Continue reading...New study finds ocean ecosystems likely to collapse in 2020s and land species in 2040s unless global warming stemmed
Wildlife species will die out and natural ecosystems collapse in the near future if the climate crisis goes unchecked, scientists have warned, as new research shows that the natural world is at far greater risk from climate breakdown than previously thought.
Catastrophe could strike this decade for some species, as key temperature thresholds are crossed. Instead of the anticipated gradual decline of species, there are likely to be a series of sudden collapses.

The North Atlantic may be a weaker climate ally than previously believed, according to a study that suggests the ocean’s capacity to absorb carbon dioxide has been overestimated.
A first-ever winter and spring sampling of plankton in the western North Atlantic showed cell sizes were considerably smaller than scientists assumed, which means the carbon they absorb does not sink as deep or as fast, nor does it stay in the depths for as long.

The UN climate talks due to be held in Glasgow later this year have been postponed as governments around the world struggle to halt the spread of coronavirus.
The most important climate negotiations since the Paris agreement in 2015 were scheduled to take place this November to put countries back on track to avoid climate breakdown. They will now be pushed back to 2021.

Think of Antarctica and it is probably sweeping expanses of ice, and the odd penguin, that come to mind. But at the time of the dinosaurs the continent was covered in swampy rainforest.
Now experts say they have found the most southerly evidence yet of this environment in plant material extracted from beneath the seafloor in west Antarctica.

Financial help from taxpayers to airlines hit by the coronavirus crisis must come with strict conditions on their future climate impact, the former EU climate commissioner and a group of green campaigners have said.
“It must be conditional, otherwise when we recover we will see the same or higher levels of carbon dioxide [from flying],” said Miguel Arias Cañete, the EU climate commissioner who led the bloc to the Paris agreement, in an interview with the Guardian. “We know the level of emissions we have to commit to [under Paris]. They [airlines] are worried about survival and will need lots of support, lots of liquidity – that gives them a big responsibility.”

Rising ocean temperatures could have pushed the world’s tropical coral reefs over a tipping point where they are hit by bleaching on a “near-annual” basis, according to the head of a US government agency program that monitors the globe’s coral reefs.
Dr Mark Eakin, coordinator of Coral Reef Watch at the National Oceanic and Atmospheric Administration, told Guardian Australia there was a risk that mass bleaching seen along the length of the Great Barrier Reef in 2020 could mark the start of another global-scale bleaching event.

The call came as she sat in her hotel room. “They gave us 10 minutes to pack up and leave,” Dr Safaa Kumari was told down a crackling phone line. Armed fighters had just seized her house in Aleppo and her family were on the run.
Kumari was in Addis Ababa, Ethiopia, preparing to present a conference. She immediately began organising a sprint back to Syria. Hidden in her sister’s house was a small but very valuable bundle that she was prepared to risk her life to recover.

Everything feels new, unbelievable, overwhelming. At the same time, it feels as if we’ve walked into an old recurring dream. In a way, we have. We’ve seen it before, on TV and in blockbusters. We knew roughly what it would be like, and somehow this makes the encounter not less strange, but more so.
Every day brings news of developments that, as recently as February, would have felt impossible – the work of years, not mere days. We refresh the news not because of a civic sense that following the news is important, but because so much may have happened since the last refresh. These developments are coming so fast that it’s hard to remember just how radical they are.
