Pressure mounts on ministers to release full evidence behind the decision to end mandatory use of a harmful chemical sheep dip

MPs are demanding that ministers release key documents and correspondence connected to the decision to end the mandatory use of a chemical sheep dip by farmers.

The call comes as the government made a partial release of evidence to explain why it ended use of the chemical. The documents, published for the first time, show ministers were advised to end use of the chemical because of its failure to eradicate the disease (sheep scab) caused by the parasite.

Mexico, Canada and US collaborate on report that concludes the three nations will have to dramatically ramp up efforts to reach 10% protection goal

North America is far from reaching national and international targets for protecting oceans, according to a first-of-its-kind report released on Wednesday.

The Dare to Be Deep report, created by a coalition of NGOs in the US, Canada and Mexico, finds that less than 1% of these countries’ oceans are protected like national parks – with only four years left to reach the 10% protection goal set in the multilateral Biodiversity Convention.

Brexit would allow Britain to renegotiate a more favourable share of catches, claims out campaigner George Eustice

Britain would have an opportunity to upend fishing quotas that give a “disproportionately large” share of catches to France if it votes to leaves the EU, according to George Eustice, the pro-Brexit minister for farms, food and fisheries.

In an interview with the Guardian, Eustice said that even if it left the EU, the UK would still respect catch limits set out to preserve stocks, some driven to near-extinction by decades of over-fishing.

Elephant populations in Tanzania’s Selous national park could collapse unless poaching and mining are urgently controlled, say WWF

Elephants could disappear from one of Africa’s most important wildlife reserves within six years unless industrial scale poaching is stopped and mining is brought under control, the WWF has said.

Selous national park, a world heritage site in southern Tanzania, has lost an average of almost 2,500 elephants a year since the 1970s. But it has now reached a crtitical stage with only about 15,000 left, according to the latest census.

Steep rise between 2010 and 2014 shows link between EU’s renewable energy mandate and deforestation in south-east Asia, say campaigners

Leaked trade industry figures show a five-fold increase in the use of palm oil for biodiesel in Europe between 2010 and 2014, providing new evidence of links between deforestation in southeast Asia and the EU’s renewable energy mandate.

The leaked figures, which the Guardian has seen, show that 45% of palm oil used in Europe in 2014 went to biodiesel, up from 8% in 2010.

Summer stayed into autumn in many parts of Australia. Bondi image from www.shutterstock.com

It’s the same old story: with 2016 on track to become the hottest year on record globally, and record-breaking heat already evident around the world, Australia has just experienced its hottest autumn on record.

Figures from the Bureau of Meteorology indicate Australia has experienced its hottest autumn on record. Bureau of Meteorology

The Bureau of Meteorology has reported that for average temperatures across Australia, this has been the hottest March-May period ever recorded – beating the previous record, set in 2005, by more than 0.2℃.

Within this period, March was also the hottest on record, while April and May were each the second-warmest in a series extending back to 1910.

Temperatures were well above average across much of the country, especially in the east. Bureau of Meteorology Why so hot?

El Niño events tend to cause warmer weather across the east and north of Australia and the major El Niño of 2015-16 undoubtedly contributed to the extreme temperatures experienced across these areas.

However, climate change also played a significant role in our warmest autumn. Previous work, led by ANU climatologist Sophie Lewis, indicates that the human influence on the climate has made a record-breakingly hot autumn roughly 20 times more likely.

In other words, without climate change we would be much less likely to experience autumns as warm as this one has been in Australia.

How we’ll remember autumn 2016

In the past few months, Australia has seen many extreme hot weather events. Melbourne experienced its warmest March night on record, while Sydney had a run of 39 days with daytime highs above 26℃, as the summer heat continued long into March.

But it’s the coral bleaching event on the Great Barrier Reef that will likely linger in our memories the longest. Some 93% of the reef was found to be affected by bleaching and recent surveys have revealed that more than one-third of coral in the northern and central parts of the reef have died.

Without climate change, a bleaching event like this would be virtually impossible.

The extreme heat over Australia this autumn and the associated damage to the reef are also having an effect on the election campaign. As public concern over the future of the reef grows, the parties are being asked to defend their climate change policies.

Both major parties have made election commitments to the reef, with the Coalition announcing an extra A$6 million to tackle crown-of-thorns starfish (adding to a further A$171 million committed under the 2016 budget), and Labor an extra A$377 million over five years (A$500 million in total). While both Labor and the Coalition aim to improve water quality in the reef through their policies, the coral bleaching and death this year is linked with warm seas.

Whether we’ll be able to save parts of the reef largely depends on whether we reduce our greenhouse gas emissions and manage to prevent the rising trend in temperatures from continuing.

Energy inefficient and substandard construction in developing countries locking the world into high greenhouse gas emissions for decades, warns Fatih Birol

Buildings currently being constructed at an increasing rate in developing countries are locking the world into high greenhouse gas emissions for decades to come, the world’s leading authority on energy has warned.

Fatih Birol, executive director of the International Energy Agency, told the Guardian that the world’s number one priority in tackling climate change must be to ensure those buildings meet higher standards of efficiency and safety.

Pact addresses concerns that burgeoning output from renewables is putting strain on electricity grid and pushing up prices

The German chancellor, Angela Merkel, has hammered out a deal with state premiers on the latest reform to Germany’s renewable energy law aimed at curbing the costs and controlling the speed of the roll-out of green power sources.

After a meeting with the leaders of Germany’s 16 states that stretched into the early hours of Wednesday, the government agreed to cap the expansion of onshore wind power at 2.8 gigawatts in capacity per year.
