New Scientist - Earth

· Steep decline of wasps and other flying nasties is a bad sign. Aphids, midges and wasps are being added to the list of rapidly vanishing insects. It’s another alarming sign of a sixth mass extinction, says Olive Heffernan

· The mass extinction that might never have happened. An ecological catastrophe 201 million years ago supposedly paved the way for the rise of giant dinosaurs, but it may not have happened that way after all

· A tech-destroying solar flare could hit Earth within 100 years. If the sun spews“superflares” as often as other stars, one could take down power systems, damage the ozone layer and destroy satellites in the next century

· How to clean up the dirty water Puerto Ricans are drinking. Nearly a month after Hurricane Maria, many people on Puerto Rico are still without clean drinking water and have resorted to wells on a contaminated site

· Ophelia shows many hurricanes could reach Europe in the future. Tropical cyclones often get to Europe but normally they have weakened by the time they get there. Not any more, thanks to climate change

· The next supercontinent: Four ways Earth could reshape itself. Plate tectonics is a slow-grind drama with some dramatic plot twists– these scenarios show how Earth might look in 250 million AD

· It looks like an oxymoron, but Earth optimism is worth a try. Decades of environmental doom-mongering have fallen on deaf ears. Maybe a new environmental campaign with a message of hope is just what we need

· It?s time artists woke up to the power at their fingertips. The recent Lofoten Islands biennale and The New We, a group show now on in Norway, both get artists to engage with nature– but they don't seem keen to commit

· Is positive thinking the way to save the planet?. Move over doom and gloom, there is a new environmental movement in town. Earth optimists say focusing on small successes is the way forward

· Air pollution blamed for 500,000 early deaths in Europe in 2014. The biggest source of harm was particulate matter from domestic stoves, but nitrogen dioxide from cars is also linked to many premature deaths

· California?s wildfires powered by perfect storm of fire hazards. Low humidity, parched vegetation and warm winds have led to fires that have killed at least 17, left over 150 people missing and destroyed over 2000 homes

· I want to show the courts who?s to blame for climate change. Climate modelling allows us to link extreme weather, climate change and emissions so we can use the law to hit big oil where it hurts, says Myles Allen

· Cold climate may have driven ancient humans? move out of Africa. East Africa became colder and drier around 75,000 years ago, just when modern humans were apparently migrating out of Africa

· We just found nineteen new species of gecko in one tiny area. The discovery of so many closely-related vertebrate species within such a small area is unprecedented

· Grass-fed beef is bad for the planet and causes climate change. Supporters like Prince Charles say raising cattle on pastures can be good for the environment, but the sums have been done and their claims don’t add up

· Early farmers may have polluted the sea 4000 years ago. Heavy metals including cadmium and lead are unusually common in sediments from the South China Sea, hinting that run-off from farms was spilling into the ocean 4000 years ago

· Kids suing nations over climate change wildfire links are right. A group of children is aiming to take 47 nations to court over links between climate change and forest fires. Science is on their side, says Richard Schiffman

· Why Puerto Rico still has no electrical power and how to fix it. Hurricane Maria is long gone but almost all of Puerto Rico has been left without a power supply, and restarting the national grid from scratch will be very difficult

· Energy from evaporating water could rival wind and solar. Water evaporating from lakes and reservoirs could provide a huge amount of electricity, but scaling up the technology will be tricky

· A few cold drops falling through a cloud could create a downpour. One raindrop that is less than 4°C cooler than the surrounding cloud can trigger a rapid burst of microdroplets, which can spawn a sudden rainstorm

· Mexico City quake: A few seconds? warning can still save lives. The recent earthquake in Mexico City shows even the best tremor alarms sometimes only go off seconds before– but clever planning can mean those few seconds save many people

· Super-Earths draw asteroids to other worlds, which may seed life. Asteroid collisions can be destructive– just ask the dinosaurs – but they also bring key ingredients for life. Super-Earths can draw them to nearby worlds

· What a surprise? the end of the world has been delayed, again. The planet Nibiru was meant to wipe us out on Saturday. Undeterred by a no-show, doomsday theorists are already peddling more nonsense, warns Geraint Lewis

· Huge space rocks could have helped start Earth?s plate tectonics. Nobody knows how or why plate tectonics got started on Earth. But new evidence suggest collisions with space rocks millions of years ago may have something to do with it

· The hurricane hunter who got up close and personal with Irma. While most people flee the world’s mightiest storms, meteorologist Jason Dunion buckles up and flies straight into them

· The nuclear stalemate is crumbling? what are our options?. The two-party game theory of the cold war doesn't work any more– time for a new approach

· Our terrifying energy future leaves us with uncertainties. We could outrun environmental disaster by ditching fossil fuels for safer options, but will we? Three new books paint a scary picture by refusing to commit

· There is no way to spot big earthquakes ahead of time. Large earthquakes look just like small ones when they start out, so early warning systems have no clues to help figure out if a quake is going to be huge

· Lightning storms triggered by exhaust from cargo ships. The world's busiest shipping lanes have twice as many bolts of lightning as nearby areas, and ships pumping soot into the air seem to be responsible

· Another lost tribe feared massacred? how can we save the rest?. Should we leave uncontacted tribes alone or try to usher them into the modern world to protect them from violence and disease, wonders Curtis Abraham

· Hurricane Maria confirms dire warnings for 2017 hurricane season. As Hurricane Maria continues to cause destruction, predictions that 2017 could be the worst hurricane season since 2010 are being borne out

· Handheld scanner divines how nutritious your food really is. Climate change and soil degradation are depleting the nutrients in crops, but now a scanner can analyse grain to help farmers mitigate problems as it grows

· Mexico hit by second huge quake caused by same tectonic strain. The country has been struck by its second big earthquake in less than two weeks, causing dozens of buildings to collapse

· Stunning shots capture how we interact with our natural world. These evocative pictures by photographer Lucas Foglia catalogue his quest to capture our turbulent relationship with nature

· Secrets of butterfly wing patterns revealed by gene hacking. Butterflies' wings have extraordinary patterns and colours, and it turns out they are controlled by a single "master gene" that performs many roles

· Thousands likely to be killed by Hurricane Irma?s deadly legacy. Toxic chemicals released by floodwaters, stress, infection and dangerous working conditions will all contribute to hurricane death toll years after winds die

· Could we store carbon dioxide as liquid lakes under the sea?. We need to get carbon dioxide out of the atmosphere to slow down climate change, and perhaps deep-sea trenches would be a good place to put it

· No, climate science isn?t wrong, and yes, global warming is real. A study suggests we can emit three times more carbon than we thought and still avoid 1.5°C of global warming - but the results are not as straightforward as they seem

· Fear and trembling, from The Great Quake to Quakeland. Detail or range? Two new books offer very different approaches to the fascinating and violent world of earthquake science

· A rushed response to Hurricane Irma could cause bigger disasters. We must prepare for the bigger storms to come, but if planners get it wrong, their efforts to protect people could make future mega-disasters even worse

· Christmas Island?s only echolocating bat has gone extinct. The Christmas Island pipistrelle is no more, and the world's largest antelope is at risk, according to the latest update to the Red List of Threatened Species

· Mysterious lights in the sky seen after Mexico?s huge earthquake. Magnitude isn’t the only demonstration of an earthquake’s power. For centuries, mysterious lights have popped up in the wake of strong quakes

· The hottest place ever recorded on Earth?s surface was 2370C. When a rock from space crashed to ground 38 million years ago, it briefly heated the impact zone to 2370°C, the hottest temperature ever recorded on Earth’s crust

· Air pollution changes what bugs colonise our airways. Higher levels of pollutants in the air correlate with reduced diversity of bacteria in our nose, hinting at a possible mechanism for why pollution causes disease

· Extreme wildfires in the US could lead to long-term lung damage. This year’s exceptional wildfire season could drag on until December, and the resulting air pollution poses a serious risk to people’s health

· The Caribbean will be recovering from Hurricane Irma for years. Florida escaped the worst of hurricane Irma, but islands like Puerto Rico and Cuba were hit hard– and they face a hard road back to prosperity

· Stripy ponds in the Utah desert help green the bone-dry land. Multicoloured patchwork ponds in this desert play a key part in tapping sources of potassium chloride, a vital fertiliser

· Florida suffers coast-to-coast battering by Hurricane Irma. After striking the Caribbean islands and leaving several close to uninhabitable, Hurricane Irma has made landfall in Florida and caused untold damage

· Gel-like ice is the lightest form of water ever discovered. A type of simulated water ice has a molecular structure so sparse it’s like frozen candy floss, making it the lightest type of ice we’ve ever seen

· Hurricane Irma tears across Caribbean leaving chaos in its wake. The tropical storm has left a trail of devastation across the region, reducing islands to wreckage and leaving at least 14 people dead

· Mexico on tsunami alert after biggest earthquake in 85 years. The US Geological Survey reported the earthquake's magnitude as 8.1, making it the biggest earthquake in Mexico since 1932

· Hurricane Irma?s epic size is being fuelled by global warming. The monster storm has the second strongest wind speeds ever recorded for an Atlantic hurricane, and its growth was fuelled by warming waters

· Eight low-lying Pacific islands swallowed whole by rising seas. As sea levels have risen due to climate change, uninhabited islands in Micronesia have vanished beneath the waves - but some last longer than others

· Europe?s last wildernesses are under threat? can we save them?. A glut of new dams and motorways in eastern and south-eastern Europe will bring prosperity, but could mean unique flora and fauna will soon be gone for good

· Houston got rich on urban sprawl, and now it?s paying the price. Unfettered economic growth guaranteed Houston's vulnerability to a natural disaster that hit the poorest hardest, says analyst Owen Gaffney

· Asteroid Florence buzzes Earth in closest fly-by since 1890. A 4.4-kilometre-wide space rock whizzed past Earth on its closest orbit in over a century. This asteroid won’t get this close again until after 2500

· The cities in the firing line for the next Hurricane Harvey. Of five cities set to see the worst losses from flooding by 2050, three are in the US. Yet the country is unprepared for worsening weather brought by climate change

· India floods: Apartment building collapses in Mumbai. A five-storey building has collapsed in the Indian city of Mumbai, following torrential monsoon rains that have also caused widespread floods

· Explosions heard at flooded Texas chemical plant after hurricane. Two explosions and black smoke have been reported at the flooded Arkema plant in Crosby, Texas, which has lost power and backup generators it needs to keep volatile chemicals refrigerated

· ?Mother? coral reefs are breathing life into their neighbours. Strong currents in the Red Sea are sweeping huge masses of larvae-rich sea water from one reef to the next

· Brazil rejects bid to drill for oil near unique Amazon reef. Total has had its drilling licence turned down, with Brazil’s environment agency saying the French oil giant has failed to address the environmental risk of oil spills

· Taking Earth?s pulse: How to predict eruptions from space. Our planet’s inner stirrings manifest as moving bulges on the surface. Now an eye in the sky is watching them to help predict disasters and save lives

· The brothers who went missing on a glacier for almost 90 years. In March 1926, three brothers and a friend climbed up to a hut overlooking the Aletsch glacier in Switzerland. They were never seen again– until their bones were found in 2012

· Texas may be just as vulnerable when next big hurricane hits. Houston is battling unprecedented floods from Hurricane Harvey– and yet Texas’s plans to protect itself from floods remain stalled

· Large non-native species like donkeys can boost biodiversity. Many large animals are now living far outside of their native ranges, and that may actually be helping conservation

· Secret lifestyle of the dodo revealed for the first time. A study of dodo bones has revealed how the legendary birds matured, bred and moulted, and explains discrepancies in sailors’ descriptions of them

· We really can run the world on renewable energy? here?s how. Can the planet change over to 100 per cent clean and renewable energy fast enough to avoid extreme climate impacts? Yes it can, says Mark Jacobson

· Wiping out a population of animals might help the species. Mass deaths might not be all bad, because local die-offs could help to ensure the survival of the species as a whole

· The push for UK fracking may be 55 million years too late. Cuadrilla is pressing ahead with a project to drill for shale gas in Lancashire, but a geologist thinks plans for industrial-scale fracking may be doomed

· Can a crowdsourced mega-forest offset Trump?s climate chaos?. It's an appealing idea, a vast forest to soak up the extra carbon released due to Trump's policies, but it may not be so easy in reality, says Olive Heffernan

· Weird creatures are spreading polluting plastic through the sea. Plastic particles sink to the seabed after being eaten and excreted by animals called larvaceans, which could be why we see less floating plastic than expected

· Back to the wild: How nature is reclaiming farmland. Farmland is shrinking for the first time on record thanks in part to consumer choices. What does this mean for the environment and the future of food?

· There are almost 100 new volcanoes hiding under Antarctic ice. The 91 newly found volcanoes lurk beneath the vulnerable West Antarctic ice sheet and could accelerate its demise

· This year may be one of the worst ever for Atlantic hurricanes. Between 14 and 19 storms are predicted to sweep across the Atlantic from June to November this year, threatening the US and other countries

· Fighting to breathe in the face of Canada?s wildfire emergency. British Columbia is facing its worst documented wildfire season in almost 60 years– Mika McKinnon went to the city of Kamloops to find out why

· Farmland is in retreat. We should make the most of that. Now that more land globally is being revegetated than cleared, we need to figure out how to use this force for ecological good. But it won't be an easy sell

· The BBC should stop giving unwarranted airtime to Nigel Lawson. The broadcaster had tough questions for Al Gore and then gave space to false claims of a prominent climate sceptic. This is a recipe for spreading misinformation

· Mystery of missing tsunamis explained by geological model. Massive debris flows below the waves can trigger devastating tsunamis, but sometimes they generate the merest ripple– now we know why

· Al Gore: The return of climate science?s preacher man. Climate denialism seems to loom large, but after 10 years delivering his message globally, Al Gore believes we’re on the road to salvation

· Early humans may have seen a supervolcano explosion up close. Two ancient teeth found on Sumatra suggest early humans were there when the island’s supervolcano erupted 71,000 years ago

· There is a good case to unleash job-killing AI on the high seas. Life on a container ship can be hellish, so maybe we shouldn't mourn the loss of these roles too much as the first crewless vessels take shape, says Paul Marks

· Sea snakes are turning black in response to industrial pollution. Indo-Pacific sea snakes living in polluted waters near industrial areas have darker bodies– perhaps because pollutants bind better to their dark skin pigment

· Largest ever dinosaur may have been as long as 7 elephants. Analysis of fossils from six Patagotitan mayorum dinosaurs suggests the animals may have weighed 62 tonnes and measured more than 35 metres from nose to tail

· Americans already feeling effects of climate change, says report. A leaked report says evidence that humans are responsible for climate change is strong– but it remains to be seen how the Trump White House will react

· Largest ever wildfire in Greenland seen burning from space. The blaze is the biggest ever detected by satellites– and a recent increase in fires in the region could well be a result of the rapid warming in the Arctic

· Satellite shows clear-up operation after severe floods in China. The photo shows teachers cleaning the mud from a school sports ground and running track in Jilin province, north-east China– an area devastated by floods

· Is our environmental future better than we thought?. Two possible visions of our future are competing for our attention: an Anthropocene desert of homogenised mongrels and a virtual supercontinent teeming with new species

· NASA?s planetary protection officer will defend Mars, not Earth. A NASA job advert has made for excited headlines, but the agency isn’t hiring someone to protect us from aliens – it wants someone to protect alien microbes from us

· Al Gore?s Inconvenient Sequel could just make climate rift worse. Perhaps the veteran Democrat should have stayed in the wings for the follow-up to hit documentary An Inconvenient Truth, suggests Adam Corner

· Deforestation may soar now Colombian civil war is over. Now that the 52-year Colombian conflict that killed tens of thousands of people is over, the country's forests are once more under threat

· Voyage to study Earth?s mostly submerged hidden continent begins. The research ship JOIDES Resolution is on its way to take samples from Zealandia, a continent that lies mostly below the waves

· Quantum gravity detector will use atom clouds to survey for oil. A commercial device that uses quantum technology to detect subtle differences in gravity, should be able to detect coal, oil or pipes underground

· Throwaway culture: The truth about recycling. We take it for granted that recycling is the best way to dispose of waste. But is that just greenwash? New Scientist sorts through the trash so that you can make up your mind

· Taking back control must not mean a return to overfishing. The return of North Sea cod to sustainable status has been greeted with glee in the UK. We must not let Brexit jeopardise this success

· Bringing our soil back to life with the latest in earth science. David Montgomery's Growing a Revolution says farming can save the soil and even address climate change– can his optimism be justified?

· Robot spots signs of melted fuel at submerged Fukushima reactor. An underwater robot captured images believed to be the first signs of melted nuclear reactor fuel that sank after the plant’s 2011 failure

· Yellowstone National Park hit by 1400 earthquakes in six weeks. A major quake swarm has hit Yellowstone National Park - but it’s unlikely to be a sign of an impending volcanic eruption, according to geologists

· The great polar mystery: closing in on the truth. What happened when all 129 men in John Franklin’s Arctic expedition vanished in the late 1840s? We’re finally putting the pieces together

· Australia to expand commercial fishing in marine sanctuaries. Fishing operations will be rolled out in Australia’s protected marine areas, in a move that could endanger fragile ecosystems

· California climate case turns up the heat on fossil fuel giants. Coastal communities in the US state are suing oil, gas and coal giants for the cost of dealing with sea level rise. Expect more of this, says Sophie Marjanac
