· Alarm as climate sceptic named head of US environment agency. Scientists within the EPA say work continues as usual for now, but they worry about potential changes when Scott Pruitt– a climate change sceptic – takes charge

· The father of the Gaia hypothesis shares his greatest invention. James Lovelock is best known for his Gaia hypothesis, but it is a device he invented 60 years ago that accidentally helped to save the planet that we should laud him for

· How the world made us: chance and climate in the human story. Chance, geo-climatic factors and the changing landscape all have an important part to play in human evolution, argues Mark Maslin in The Cradle of Humanity

· Antarctic sea ice is very low? but don?t jump to conclusions. Drawing premature conclusions about global warming’s role in Antarctic sea ice loss is unjustified whether positive or negative. The evidence must speak for itself

· Emergency clause lets European countries beat bee pesticide ban. About half of the European Union’s member states are making use of an emergency clause to allow the use of banned pesticides that are thought to harm bees

· Crews race to fix California dam before more rain falls. Heavy rains caused erosion and a partial collapse of spillways at a California dam - and more rain is forecast, threatening to overflow it again and flood towns

· More people now believe human-made climate change is happening. The proportion of people in the UK who accept climate change is happening and is largely human-made has risen from 57 per cent three years ago to 64 per cent now

· Simple equation shows how human activity is trashing the planet. The impact of industrialised societies on Earth has been described in a mathematical formula that should scare us all, says Owen Gaffney

· Climate change is already battering hundreds of animal species. Almost half of all threatened land mammals and a quarter of threatened birds may be feeling the pinch as a result of habitat loss and other changes

· Ocean acidification may be good for thriving marine snails. Although acidifying oceans are expected to be bad news for marine life overall, tiny snails prove that there will be winners as well as losers

· The video installation that makes us swim in our own mess. A work by Ethan Turpin, on display at The Animal Museum's Entangled exhibition in Los Angeles, forces us to confront the way we have polluted the ocean

· Long-lost continent found submerged deep under Indian Ocean. The continent of "Mauritia" sunk as it was stretched out like plasticine by the plate tectonics that drew India and Madagascar apart some 85 million years ago

· Planet Earth makes its own water from scratch deep in the mantle. Computer simulation confirms that water can form within our planet rather than arriving from space, and the process may explain mysterious deep quakes

· US scientists can look to Canada for ways to fight a crackdown. The Trump administration seems to want to rein scientists in, just as Canada did until recently– and it's there we should look for lessons in fighting back

· Earth?s water must have arrived here earlier than we thought. Our best theory said meteorites brought water to Earth 4.5 billion years ago, now it seems they struck far earlier, while our planet’s core was still forming

· Earth?s water must have arrived here earlier than we thought. Our best theory said meteorites brought water to Earth 4.5 billion years ago, now it seems they struck far earlier, while our planet’s core was still forming

· Carbon seen bonding with six other atoms for the first time. A pyramid-shaped carbon molecule breaks one of the most basic lessons of chemistry textbooks– bonding with six other atoms instead of the typical four

· The paradox powering Earth?s magnetic field. Our planet’s protective force field appears to be billions of years older than the mechanism that got it going. So what really made Earth magnetic?

· Future air conditioning could work by beaming heat into space. Physicists have achieved record temperature reductions of more than 40°C using radiative cooling, which beams heat through the atmosphere

· People prepare to fight their governments on climate change. Despite record-breaking climate change, some leaders may be reluctant to cut emissions. The Paris Agreement may give people the clout needed to force them to act

· Mystery Antarctic circle means ice is melting from surface down. A 2-kilometre-wide circle spotted during on an Antarctic ice shelf was thought to be caused by a meteorite. It now looks like winds and melt are to blame

· Large asteroid impacts may be rare, but we should be prepared. It would be wise to heed calls to build a dedicated rocket primed to defend Earth against a large incoming asteroid or comet, says Geraint Lewis

· Animal magnetism: Why dogs do their business pointing north. Dogs align north-south when defecating, foxes pounce north-east, and that’s just the start. Where does this magnetic sense come from – and do we have it too?
