· Asteroid strike may have forged the oldest rocks ever found on Earth. The oldest rocks ever found are over four billion years old and we don’t know how they formed – but a massive asteroid bombardment may be responsible

· The Meg: Real Megalodon shark would eat Jason Statham for breakfast. Jason Statham’s new film The Meg looks gloriously silly and good luck to it, but it got us thinking about what its giant prehistoric shark was really like and why it died out

· Don?t give up, we can survive even a Hothouse Earth. Bad news on the climate should lead neither to despair nor unfounded optimism. Instead, we need to roll up our sleeves and prepare for life on a drastically changing planet

· California?s worst wildfire in history is now the size of Los Angeles. Firefighters are battling high winds and extreme heat as they try to slow the spread of the biggest wildfire ever recorded in California

· Global warming may become unstoppable even if we stick to Paris target. There could be a planetary threshold beyond which the earth will keep warming even if we stop pumping out more fossil fuels - the so-called 'Hothouse Earth' scenario

· A weird Pacific cycle could make the Arctic warm up even faster. The Pacific Decadal Oscillation (PDO) is cyclical, switching from warm to cold phases every 20 years or so. When it switches again it could speed up Arctic warming

· Did ancient Mayan civilisation collapse because of a sudden drought?. We have the best evidence yet that there was a prolonged drought at the time of the demise of the classic Mayan civilisation - and could explain why it collapsed

· Extreme heat: Why its origins could lie deep in the Atlantic. Swathes of the northern hemisphere are smashing temperature records. Could it be because we’ve broken the ocean currents that stabilise our weather?

· Earth Overshoot Day? what to make of this moment of reckoning?. Earth Overshoot Day is a hugely popular way to highlight our global environmental impact. Here are two views on it...

· Wild animals are turning nocturnal to keep away from humans. Dozens of species all around the world are abandoning the day and becoming more active at night, to avoid contact with humans

· Alarm as ice loss from Antarctica triples in the past five years. The loss of Antarctica’s ice has been accelerating ominously since 2012, and could lead to big rises in sea level if the rate of loss keeps increasing

· EU will limit the use of palm oil as car fuel but won?t stop it. The European Union will make only minor tweaks to“renewable” energy policies that are actually increasing greenhouse gas emissions and driving deforestation

· Why tidal power won?t solve the world?s renewable energy needs. There are widespread calls for the UK government not to abandon a trailblazing tidal power project, but this energy source is no green panacea, says Hans van Haren

· Finally we can power the planet on renewables alone? here?s how. Ditching fossil fuels to go 100 per cent renewable is a dream within reach– thanks to new tech that keep things humming even when wind and sun aren’t there

· The volcanic eruption on Hawaii is now making an acidic fog. As lava from Kilauea plunges into the Pacific Ocean, clouds of hot acidic steam are being blasted off– and the eruption shows no signs of slowing down

· Plastic waste is a problem? but some solutions are even worse. Plastics have done wonders for hygiene and human health. We need to fix the waste problem– but don’t throw out the baby with the bath tub

· A third of?protected? nature zones are quietly being ruined. The world’s nations have set up 200,000 protected areas in which nature is supposed to flourish, but in many cases the protection is pretty much theoretical

· Someone is wrecking the ozone layer again. They must be stopped. For the health of our planet, and ourselves, we must find and foil those who breach crucial environmental treaties, says Lesley Evans Ogden

· Worst-case climate change scenario is even worse than we thought. A possible future that climatologists treat as the worst of the worst, because it would produce huge greenhouse gas emissions, might lead to even more emissions than believed

· Harsh: Europe?s cannabis died just as the first farmers arrived. Cannabis– the source of the drug marijuana – virtually disappeared from Europe just as farmers arrived, so they didn’t get the chance to grow it for another 4500 years

· Drones plus AI help to spot sick trees and plants in time. Drones fitted with multispectral cameras are scanning forests for beetle attack, and orchards and vineyards for signs of disease before it’s too late

· Lizards keep evolving toxic green blood and we don?t know why. All the green-blooded lizards in the world live in New Guinea, but it turns out the trait has evolved there independently at least four times

· Biodegradable plastic: Waste that eats itself. Plastics that degrade on disposal already exist, and are getting better. But they won't solve the plastic trash problem on their own – and here's why

· Fertiliser feeds us but trashes the climate? now there?s a fix. The way we make ammonia for fertilizer was developed a century ago and produces more than 1 per cent of all carbon emissions. Now we may have a replacement

· Hawaii?s erupting volcano may blast out ?10-tonne cannonballs?. As Kilauea continues erupting, lava is mixing with water, creating steam that could trigger massive explosions and throw large rocks up to a kilometre away

· The tides are getting stronger thanks to the shifting continents. The ocean tides are the strongest they have been for millions of years, and they will get stronger for several million years to come– because of the position of the continents

· Rich nations restore their own forests but trash those elsewhere. As countries get richer, they start replanting their forests– but this is not a big environmental gain because they “export” the deforestation to poor countries

· We messed up our figures on how much carbon dioxide is too much. Climatologists have tried to set a“carbon budget” that tells us how much greenhouse gas we can emit and stay below 2°C, but their efforts have only caused confusion

· It is worth valuing trees, but all deserve our respect. The benefits trees bring to our lives are now being quantified by a band of treeconomists, an approach that could help us give trees the respect they deserve

· Towing icebergs to Cape Town is a poor way to halt water crisis. Hauling chunks of polar ice to dry regions to provide fresh water sounds tempting but there are many reasons to reject it, says Olive Heffernan
