Mayor of London will submit statement and evidence in high court case brought by ClientEarth on the air pollution crisis in the capital

The mayor of London, Sadiq Khan, has joined a high court challenge against the government over its air pollution plans, overturning the position of his predecessor, Boris Johnson. Khan filed legal documents on Thursday and can now submit a witness statement and evidence to the court on the air pollution crisis in the capital.

Environmental lawyers ClientEarth are suing the government for the second time in a year, having won a case at the supreme court in 2015 which ordered ministers to fulfil their legal duty to cut pollution in “the shortest time possible”. The new case argues the government is still failing to do this.

Hundreds of millions of people could be displaced by the end of the century due to conflict caused by global warming, says Ségolène Royal

Global warming will create hundreds of millions of climate change migrants by the end of the century if governments do not act, France’s environment minister has warned.

Ségolène Royal told ministers from 170 countries at the UN environment assembly in Nairobi that climate change was linked to conflicts, which in turned caused migration.

‘Urgent and clear need’ to limit temperature rises to protect key sites from warming, rising seas and harsher weather

Some of the world’s most famous heritage sites – from the Statue of Liberty and Venice to the Galapagos Islands – could be irreversibly damaged by climate change, a report has warned.

Historic and natural world heritage sites are already feeling the brunt of increasing temperatures, with rising seas, erosion and storms hitting Orkney’s neolithic coastal treasures and important tropical coral reefs being “bleached” by warmer seas.

In a rare move to shun tourism profits for environmental protection, 10 popular dive sites have been shut down in a bid to slow a coral bleaching crisis

Thailand has shut down 10 popular diving sites in a bid to slow a coral bleaching crisis, an official said Thursday, in a rare move to shun tourism profits to protect the environment.

The tropical country’s southern coastline and string of islands are home to some of the world’s most prized white sand beaches and scuba sites, and the booming tourism industry props up Thailand’s lagging economy.

Increase fuel efficiency of heavy good vehicles that cause a quarter of Europe’s traffic carbon emissions to meet climate targets, says clean corporate alliance

An alliance of companies including Ikea, Nestle and Heathrow airport have called on the EU to pass new laws cutting truck emissions within two years, to meet promises made at the Paris climate conference.

Heavy duty vehicles make up less than 5% of Europe’s road traffic but chug out a quarter of the sector’s carbon emissions – more than airplanes – and their fuel efficiency has hardly changed in two decades.

Ancient air bubbles preserved in Antarctic ice. The Ellsworth Mountains Project

The unfortunate manner in which the latest phase of restructuring of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) has played out has raised questions about Australia’s scientific capability and our ability to meet international responsibilities.

Faced with a budget cut of A$115 million, some 275 staff have apparently been identified for redundancy (though the final number may be as high as 317). Many of them are scientists contributing to long-term sea, air and climate science programs. The restructure is geared towards focusing CSIRO’s attention on the question, as framed by chief executive Larry Marshall, of “how can we find solutions for the climate we will be living with?”

The problem is that the programs at threat form the backbone of national and international research efforts. Virtually all of them are critical for helping us mitigate and adapt to future climate.

In 1979, the great scientist Carl Sagan wrote:

We live in an extraordinary age. These are times of stunning changes in social organisation, economic wellbeing, moral and ethical precepts, philosophical and religious perspectives, and human self-knowledge … Had we been born fifty years later, the answers would, I think, already have been in.

Australian scientists do indeed live in extraordinary times, but not necessarily for the best of the reasons. We may be living through a remarkable period of discovery, but recent events are a timely reminder that we must all work harder to manage the precious resources available to science if we’re not to threaten decades of investment and hard work.

Global response

The cuts have been met with very public protests, including those by former US vice-president Al Gore and the World Climate Research Program.

The most public of all staff to be earmarked (so far) for redundancy is Dr John Church. He is arguably the world’s leading expert on global sea level rise, a role that is more important than ever for adapting to the effects of climate change. It’s a decision so extraordinary it was even reported in The New York Times.

The facilities at risk from CSIRO cuts are used by research teams around the world.

The threat to close the “Ice Lab” involves a facility unique in the world for analysing ancient air trapped in Antarctic ice, helping understand future climate-carbon feedbacks.

The Tasmanian Cape Grim atmospheric station is crucial for monitoring greenhouse gas levels in the southern hemisphere. Only last week it confirmed CO₂ concentrations now exceed 400 parts per million, likely the last location on the planet to do so.

And just last month, CSIRO staff (of which Dr Church was a senior author) led a Nature Climate Change article showing anthropogenic emissions of greenhouse gases have dominated global sea level rise since 1970. This is crucial work for understanding the source(s) of sea level rise. Such work can inform major infrastructure projects such as Brisbane Airport’s new runway, which is being constructed four metres above minimum required standards to accommodate future coastal flooding.

A wider problem

The funding gap CSIRO faces is a story common to many in the scientific community. Some sectors in the 2016 budget continue to enjoy some funding increases, such as the A$200 million for Antarctic science and A$100 million for Geoscience Australia.

But others have experienced cuts, most notably the Australian Research Council. The ARC has received a further 10% cut on the back of a succession of cuts over recent years.

Putting aside the effect on staff morale and the observation that government science spending has a strong multiplier effect on economic growth, the shortfall of funding in some quarters has immediate implications for how we best co-ordinate our efforts as a community.

Targeted, industry-focused projects are an essential part of a thriving scientific culture in Australia. But the threatened erosion of public science and the loss of capacity in areas of expertise CSIRO has taken decades to build represent a loss to all.

While the recent focus has been on climate science, there are salutary lessons from events of recent months if we are to minimise the impact on this research field and others in the future.

Where to from here?

Like any sector, science needs stability. The cuts have to stop and ideally reverse. If we keep trimming budgets, there will come a point where whatever capacity we have will only be a token effort.

The recent announcement that a CSIRO climate change centre will be established with 40 staff in Hobart is most welcome, but details are sketchy. A major concern regarding all these decisions are how these cuts and developments align with the efforts of the rest of the community.

Reports that the Bureau of Meteorology and Australian Antarctic Division learnt of the proposed cuts in capacity only after the decisions had been made are remarkable if true.

If a realignment of priorities in an institution is to take place, we need to make sure that these decisions are made with wider consultation and as much lead-in time as possible so the scientific community can make the best of a bad situation.

Recently, the Australian Academy of Science announced a welcome, urgent review of national climate science capability. (If you’re part of the community, submissions must be made by June 5, so hurry.)

Announcing cuts that have implications for others without discussion doesn’t help science, it only stifles findings. I hope the CSIRO climate change science centre has been developed in consultation with others and the 40 staff identified are the number truly required.

We need to make sure everyone is talking to one another. Only last week, the CSIRO released its Australia 2030 report, modelling various scenarios for Australia’s future. One scenario is called “weathering the storm”, in which geopolitical instability increases, driven by climate change and regional conflicts.

Faced with this situation, CSIRO suggests that “the energy market relies on tried and tested energy sources such as coal rather than further developing the potential of renewables”.

To suggest under future climate change we should continue to exploit fossil fuels is a remarkable statement from a national scientific body.

We may be half-way to the great leaps in knowledge Sagan prophetically described by 2030, but our understanding of the planet and how we mitigate and adapt to change has to be better co-ordinated as a community. We need to do a lot better.

Malcolm Turnbull’s $150m pledge to boost agriculture in northern Australia comes under fire from conservationists

Malcolm Turnbull has promised to spend $150m on dams in Queensland as part of a plan to double the agricultural output of northern Australia – but which would dump thousands of tonnes of pollution on the Great Barrier Reef, according to conservationists.

The prime minister committed $130m to one dam near Rockhampton and a further $20m to feasibility studies for 14 others across the state.

Sandy, Bedfordshire Ash dieback threatens a tree that is unwittingly generous at both ends of the season

A line of trees on the green, their fresh bright leaves glazed with sunlight, take from the east and give nothing to the west. Oaks, sycamores and chestnuts bathe their crowns in the mid-morning rays and cast dark shadows on the ground, as wide as the trees are broad, as long as they are tall, with dappled haloes all around. The beeches are worst of all, offering the land beneath no chink in their green armour. No wonder so little grows under the canopy of a beech wood, a crowd of overlapping umbrellas giving shelter, blotting out the light.

Civil society organizations and Peru government institutions say United Cacao is operating illegally, but the company denies it

Two indigenous Shipibo men from Peru’s Amazon - Sedequías Ancón Chávez and Robert Guimaraes Vasquez - paid a rare visit to the London Stock Exchange (LSE) earlier this month. The reason? To present a letter addressed to Marcus Stuttard, Claire Dorrian and Umerah Akram from the LSE’s Alternative Investment Market (AIM) urging the AIM to investigate, suspend and bar a company called United Cacao Limited SEZC - as well as amend its rules and “exact more active oversight” in general.

“The nature of the crimes which the company stands accused are an important matter for AIM to address,” the letter states. “Allowing companies listed on AIM to raise capital to violate other countries’ national laws jeopardizes the “integrity and reputation” of the market, which is grounds for suspension of a company’s trading, according to AIM Rules.”
