· EU nations set to wipe out forests and not account for emissions. The drive for biofuels that international treaties wrongly consider to be emissions-free is driving plans to boost tree harvests in Europe, forgetting about associated emissions

· Rising seas could double the number of severe coastal floods. An increase in sea level of between just 5 and 10 centimetres could make devastating weather events come every 25 years rather than every 50 years

· Narwhals could help us measure melting glaciers underwater. A project off Greenland will tag whales with sensors to measure sea temperatures and ice melt in hard-to-reach places, improving predictions of sea-level rise

· Remote Pacific island found buried under tonnes of plastic waste. A tiny, otherwise pristine island is smothered by our blast from the past: vast amounts of decades-old plastic from around the world

· Unshackled, big auto will keep choking the world on diesel fumes. We now know diesel vehicles pollute more than they should to deadly effect everywhere, but the real scandal is government foot-dragging, says Olive Heffernan

· Where the wind blows: Mapping our wildest gusts. A new wind atlas will help turbines avoid the doldrums– and solve some of wind's enduring mysteries

· Hundreds of newly-discovered plants may yield new crops or drugs. Even as we discover promising new wild relatives of key crops and medicinal plants, some of them are already endangered by pests and climate change 

· Beaver dams keeps streams cool and protect sensitive fish. We used to think that beaver dams warmed up stream waters as felling trees to build them reduces shade. Now it seems the opposite might be true

· Odds on: Five scientific theories decided by wager. From the existence of black holes to the reality of climate change, over the years some big questions have been the subject of bets,  finds Michael Brooks

· Diesel fumes lead to thousands more deaths than thought. Cars, lorries and buses that drive on diesel churn out far more air pollution than standard testing procedures suggest, even without any emissions cheating devices

· UK government subsidises coal sector with356 million a year. Despite pledges to phase out coal, UK and several other EU countries still provide various tax benefits to the coal sector, according to a new report

· The UK government?s attitude to air pollution stinks. Despite debate over how many "deaths" air pollution causes, it is clear bad air damages our health, so attempts to delay rules on reducing it must be resisted

· UK?s plan to clean up its air is still inadequate, critics say. The government has published long-awaited plans to cut illegal pollution but critics have warned they are too weak to improve the UK's dirty air 

· Cutting through the smog: How air pollution shortens your life. Don’t take alarming death toll numbers at face value – the noxious gases in the air won’t kill you outright, but they will cut your time on Earth

· Cutting through the smog: 5 ways to slash your pollution intake. From cycling rather than driving to being savvy about where you walk, here are the key things that will minimise the risk pollution poses to you

· California?s wet year eases drought but many still lack water. Don’t be fooled by the superbloom. Despite record-breaking rains, California’s drought is still ongoing in four counties, and the driest five years on record will have lasting effects

· Lightning round-up: The world?s weirdest electricity. From flashes of light resembling sea monsters to vast rings of glowing red light, lightning comes in an astonishing array of mysterious flavours

· Bolt from the blue: Lightning doesn?t form like we thought. It happens somewhere on Earth 100 times a second, yet we don't know how or why. Peering into the hearts of thunderstorms is starting to illuminate lightning's mysteries

· It?s not too late to save Great Barrier Reef from politicians. Australia is pushing ahead with plans for a giant coal mine, despite the threat it poses to the imperilled reef and hints that the appetite for coal is waning

· Life could exist up to 10 kilometres beneath the sea floor. Samples from a mud volcano contain biological signatures that suggest microbes lived in the material when it was rock several kilometres beneath the ocean floor

· Public fatigue is the friend of those who would thwart science. Climate change deniers exploit disillusion brought on by often gloomy scientific findings, but evolving views on antibiotic use show it needn't be that way

· Mass bleaching hits Great Barrier Reef for second year in a row. The reef’s central portion is bleaching fast this year, following huge losses in the northern part last year – and climate change is the culprit

· US bill restricts use of science in environmental policymaking. The so-called HONEST Act promises to end secrecy in science, but will in effect cripple the EPA’s ability to develop public health regulations, say concerned scientists

· Warming drives Alaskan glacier to its lowest point in 900 years. The Columbia glacier was tipped into rapid retreat by human-caused climate warming of less than 2°C, so many more glaciers might be doomed

· How to snatch carbon emissions victory from US climate U-turn. Donald Trump's rollback on climate gives the rest of the world a second chance to do the unthinkable: put a price on carbon. Will we seize the opportunity?

· It just got harder to deny climate change drives extreme weather. The link between human activity and unusual jet stream patterns associated with extreme weather events is getting stronger, says Olive Heffernan

· Western demand for goods from China is killing 100,000 a year. Nearly a quarter of premature deaths from air pollution worldwide happen in countries that manufacture goods for export
