Experiment in the Bellingshuan Sea reveals temperature rise has more alarming implications for biodiversity in polar waters than previously thought

Marine life on the Antarctic seabed is likely to be far more affected by global warming than previously thought, say scientists who have conducted the most sophisticated study to date of heating impacts in the species-rich environment.

Growth rates of some fauna doubled – including colonising moss animals and undersea worms – following a 1C increase in temperature, making them more dominant, pushing out other species and reducing overall levels of biodiversity, according to the study published on Thursday in Current Biology.

Exclusive: Draft implementation plan lacks electricity emissions trajectory, Paris agreement alignment and low-income subsidies

The climate ambitions of the Finkel review appear to be being watered down by the government as it is implemented, according to a draft Coag Energy Council implementation strategy obtained by the Guardian.

The draft implementation plan removes a key recommendation for an agreed emissions trajectory for the electricity system, alignment with the Paris agreement and subsidised solar and batteries for low-income houses.

Are American lives simply worth more, wonder Lynne Edwards, Peter Williams, and Susan Howe. Plus letters from Bob Pike and Sheila Rigby

While I have the greatest sympathy for those who have lost friends, family, pets or property in the Texas floods (Report, 30 August), I am disgusted at the relative number of column inches and amounts of airtime devoted to its coverage. During precisely the same period huge areas of Bangladesh, Nepal and India are suffering an even greater catastrophe, with 1,200 plus lives lost and millions made homeless. Let’s get some balance here. America is a rich country and will cope, despite inept leadership. Or are we saying that American lives are worth more?.Susan HoweRoss on Wye, Herefordshire

• The contrast between the coverage of floods in Texas and floods in South Asia is stark. Live updating of trivia as well as important events from Houston; the odd report from India, Nepal, Bangladesh and elsewhere. There are probably many more people of South Asian heritage in this country than American. The implicit message is that they, and their relatives, are far less important than a pet in Houston. I don’t want Texas coverage reduced, but please take more notice of the rest of the world.Lynne EdwardsNew Quay, Ceredigion

Myron Ebell, who headed the EPA’s transition team when Trump became president, said the last decade has been a period of ‘low hurricane activity’

Conservative groups with close links to the Trump administration have sought to ridicule the link between climate change and events such as tropical storm Harvey, amid warnings from scientists that storms are being exacerbated by warming temperatures.

Harvey, which smashed into the Texas coast on Friday, rapidly developed into a Category 4 hurricane and has drenched parts of Houston with around 50in of rain in less than a week, more than the city typically receives in a year. So much rain fell that the National Weather Service had to add new colours to its maps.

Is there a link between the storm and climate change?
