China’s limits on contamination levels have sparked a recycling industry crisis. What are local and state governments doing to solve the problem?

“Did you put the recycling out?”

It’s a phrase regularly recited in millions of households across Australia, followed by a hollow rumble as the yellow-lidded wheelie bin is hauled to the curb. It’s a ritual that, in one form or another, takes place in more than 90% of Australian homes.

Using greater amounts of carbon tax revenues to stimulate clean energy research and capital investment could bolster company economics and help gain support for carbon pricing, according to new research published on Monday and coming on the heels of the latest US carbon tax push.

Disappearing butterflies | Patriarchy and religion | Protesting Trump | Getaways in a Morris Minor | Ikea

I don’t know whether to be happy or sad. No cabbage white butterfly caterpillars chomping through my veg is great, but where have all the butterflies gone (Letters, passim)? Not only have I not seen a single cabbage white butterfly this year but no red admirals, no peacocks and no tortoiseshells. Very worrying.

• As she dissected the subtle and not so subtle outrages of patriarchy experienced from Virginia Woolf to “labouring women in Mexico”, I wonder what discretion or inhibition Charlotte Higgins (Patriarchy: the return of a radical idea, 22 June) exercised not to mention the pronounced patriarchy in the Catholic church (the Holy Father for goodness sake), the male-delineated roles in ultra-orthodox Judaism, and in the various iterations (institutional or cultural) of Islam, all elided (that is to say obscured) in the one word reference to “religion”.

Hundreds of people have been evacuated from their homes as firefighters battle the blazes.

A team of six scientists has descended on Rum, a small island in the Inner Hebrides on the west coast of Scotland, to catch red deer calves. During the month-long initiative, overseen by the Isle of Rum Red Deer Project, newborns will be tagged so data can be gathered on them over the course of their lifetimes. The island is home to hundreds of deer and about only 30 people, all of whom live in Kinloch village on the east coast

Fast-spreading Xylella fastidiosa is devastating species from citrus to oak trees, but can now be detected from the air

A devastating and fast-spreading infection killing olive trees and grapevines around the world can now be detected from the air, long before symptoms are visible to the human eye.

The new technique offers hope in the battle against one of the world’s most dangerous plant pathogens, which can infect 350 different species, including citrus and almond trees, as well as oaks, elms and sycamores. Special “hyperspectral” cameras provide an early warning system by detecting subtle changes in leaf colour.

Fellow Tory MPs say foreign secretary should resign over opposition to third runway

Boris Johnson is facing growing criticism from fellow Conservative MPs over his decision to miss Monday night’s crunch vote on Heathrow despite his claim that resigning over his opposition to a third runway would achieve “absolutely nothing”.

The foreign secretary, who is on a visit to Afghanistan, said he would continue to oppose the £14bn third runway with his ministerial colleagues behind closed doors.

Koch paychecks seem to be strong motivators to lie

30 years ago, James Hansen testified to Congress about the dangers of human-caused climate change. In his testimony, Hansen showed the results of his 1988 study using a climate model to project future global warming under three possible scenarios, ranging from ‘business as usual’ heavy pollution in his Scenario A to ‘draconian emissions cuts’ in Scenario C, with a moderate Scenario B in between.

Changes in the human effects that influence Earth’s global energy imbalance (a.k.a. ‘anthropogenic radiative forcings’) have in reality been closest to Hansen’s Scenario B, but about 20–30% weaker thanks to the success of the Montreal Protocol in phasing out chlorofluorocarbons (CFCs). Hansen’s climate model projected that under Scenario B, global surface air temperatures would warm about 0.84°C between 1988 and 2017. But with a global energy imbalance 20–30% lower, it would have predicted a global surface warming closer to 0.6–0.7°C by this year.

Transport secretary claims strong support across political spectrum for third runway

The government is “cautiously optimistic” about winning a key parliamentary vote on the expansion of Heathrow airport, the transport secretary, Chris Grayling, has said, defending the controversial idea as being good for the whole of the UK.

The Conservatives, who have a three-line whip in place for their MPs, are likely to get significant Labour support in the vote on Monday after Unite called for Labour MPs to back the third runway.
