At first glance, it has been a bafflingly bad summer for butterflies. After a decent spring in the north-west and a dazzling late summer in the south-east, garden buddleias remained bereft. The only butterfly I’ve seen in good number is the red admiral, which thrived during the second-warmest September on record.

Company operating near the border with Peru has reportedly had near encounters with indigenous people living in “isolation”

Teams from a Chinese oil and gas company exploring in the remote Bolivian Amazon have reportedly had near encounters with a group of indigenous people living in what the United Nations calls “isolation”, raising major concern for the group’s welfare.

The company doing the exploring, BGP Bolivia, is ultimately a subsidiary of the state-owned China National Petroleum Corporation (CNPC), one of the biggest oil and gas companies in the world. The near encounters are reported to have taken place in the north-west of the country, close to the border with Peru and just to the east of the world-famous Madidi National Park.

Ocean health relies on a strong backbone of protection and management. Marine reserves can be part of the solution, but only if they’re constructed in the right way. Recent recommendations on Australia’s marine reserves would leave more ocean unprotected.

Marine reserves are a mix of multiple-use zones that allow activities such as mining and fishing, and highly-protected zones called marine national parks that are free of extractive activities. These marine national parks are the gold standard for protecting our oceans. Globally, less than 1% of the world’s oceans are fully protected in no-take marine national parks or their equivalents.

Australia is currently deciding how much of its ocean territory it will place in marine national parks and where. To this end, the government recently released its commissioned review of Australia’s Commonwealth Marine Reserve Network.

Such a review is welcome as Australia has yet to provide comprehensive, adequate and representative protection for its oceans. This is despite the general recognition within the Australian community that economic growth depends on a healthy and properly functioning environment.

Marine national parks play a fundamental role in contributing to ocean ecosystem function and provide a means to assess the health of areas outside of these zones that are open to greater use by humans.

This understanding of the interdependence of how we protect and sustainably use our oceans is, unfortunately, largely missing from the review’s recommendations.

The gold standard

In early 2016 the Ocean Science Council of Australia (OSCA) prepared a scientific analysis aimed at helping define what Australia’s marine reserves should deliver.

Based on hundreds of peer-reviewed publications and myriad international consensus statements from researchers on the need for strong ocean protection, the Council concluded that science-based decisions and actions should:

(1) Prevent fishing, mining and other extractive activities on at least 30% of each marine habitat, according to the international standard for ocean protection to deliver protection of both biodiversity and ecosystem services

(2) Improve representation of marine national parks in bioregions (regions of the ocean defined by particular species and climate) and key ecological features (such as the continental shelf and offshore reefs) that were already under-represented in the 2012 marine reserve plans

(3) Build and maintain large, contiguous, highly-protected marine national parks in regions such as the Coral Sea

(4) Quantify the benefits of Australia’s marine reserves so as to make their value to Australia clearer.

What the review says

The government review reflects science and community concerns in some respects, recommending for instance that more bioregions have at least one marine national park. This review also recommends more protection for some important coral reefs and there is an expansion of protection from mining in some areas.

Most importantly, the review recognises the fundamental role of highly-protected marine national park zones in the conservation of species and ecosystems. As a corollary of this, the review also recognises that “partial protection” zones within reserves are primarily used to address narrow sector-based concerns such as fishing, and result in reduced conservation outcomes (as reviewed here and here).

It requires explanation therefore that the review mostly fails to recommend zoning changes consistent with its own findings on the science. In comparison with the 2013 recommended zoning, the review’s recommended zoning would:

(1) Remove a total of 127,000 square kilometres of marine national park from the overall network, an area 1.9 times the size of Tasmania, with a net loss of 76,000 sq km

(2) Reduce by 25% the contiguous Coral Sea marine national park

(3) Demote 18 areas from marine national park zones to varying forms of partial protection

(4) Shift the location of some marine national parks from the continental shelf to offshore areas as a way of maintaining cover but further eroding representation and indeed reducing protection on the shelf where it is most needed.

Overall, the review’s recommendations would see only approximately 13% of Australia’s Exclusive Economic Zone protected in marine national parks. This falls well below the recommended international standard of at least 30% of habitats being under high protection, or indeed higher levels as recently determined.

Smoke and mirrors

The recommendations in the review are tainted by a feeling of smoke and mirrors. While some of the review’s authors suggest that their recommendations would increase protection, there would indeed be a net loss of highly-protected zones should these recommendations be adopted by the government.

Under the review’s recommendations, Australia would do a great job of protecting the deep water abyss, but achieve little to protect ocean wildlife on the continental shelf where human pressures are highest. This out-of-sight-out-of-mind approach does not address the principles of marine conservation and also departs from recommendations from the research community.

Australian marine national parks are too-often relegated to residual areas of relatively little conservation value simply because these areas are of little value to commercial interests.

The significant erosion of protection in the Coral Sea is further evidence of this failure. Much of the erosion of this important reserve reflects a shift from full protection to partial protection in order to open up more ocean to tuna fishing.

The 25% reduction in large marine national park would increase tuna catch and value by 8-10% across the fishery, worth a mere A$26,376 to individual tuna fishers. This recommendation fails both the science and the economic test.

Where to from here?

The changes recommended by the review in many cases appear to prioritise economic benefits, no matter how trivial, over conservation. This is despite conservation being the core reason behind the marine reserves.

This stands in stark contrast to international moves towards protection of large areas of the ocean as a response to ongoing declines in ocean health.

Key examples of such large-scale protection are US President Barack Obama’s recent expansion of the Papahānaumokuākea Marine National Monument over the North West Hawaiian Islands and New Zealand Prime Minister John Key’s declaration of the Kermadec Marine Sanctuary in New Zealand’s waters.

Australia still has a major opportunity to protect and secure its marine ecosystems and make a significant contribution to global ocean conservation. At the same time we can develop important economic activities such as fishing and mining. Large and well-managed areas are going to become more important, not less, as climate change intensifies.

This will require the federal government to acknowledge and build on the global body of science and create a backbone of representative marine national parks. This will include retention of the Coral Sea’s high level protection and resisting the temptation to shift of marine national parks offshore. At a time of great environmental change, these moves are not just important, but urgent.

Spending three months inside a metal container on board an icebreaker in the Southern Ocean, filtering water while attempting to ignore freezing temperatures and huge ocean swells outside. It’s not everyone’s idea of fun … but it’s what I’ll be doing next year, in the name of climate science.

From late December 2016 to March 2017 I will be on board the Russian research vessel Akademik Treshnikov, taking part in an expedition that will take me and 54 other scientists from 30 countries on a complete lap of Antarctica – the first international research expedition to circumnavigate the frozen continent.

The Antarctic Circumnavigation Expedition (with the funky abbreviation ACE) is the first project run by the Swiss Polar Institute, and involves 22 projects covering different aspects of the biology, physics and chemistry of the Southern Ocean.

Rough ride

We’re not expecting the conditions to be particularly fun – but it will be worth it. A better understanding of Antarctica and the Southern Ocean surrounding it is critical – not just for the preservation of this pristine environment but also for the whole planet.

The Southern Ocean is massive. It is also really far away from everywhere, which makes it hard for scientists to go there and study it. On top of that, there is no land at these latitudes to stop waves from building up, so waves can get really big, making the Southern Ocean a less than ideal environment for scientific work. I’m expecting that all of us will get seasick at some point.

Because of the size and isolation, our understanding of the physics, chemistry and biology of the Southern Ocean is not very good. What we do know is that this region is disproportionately important for the planet’s climate. For example, it was responsible for storing an estimated 43% of the carbon dioxide produced by humans between 1870 and 2005, and 75% of the overall oceanic heat uptake.

The ACE expedition is a unique opportunity to collect data in the Southern Ocean. The voyage will set off from South Africa, visiting all of the Southern Ocean’s main islands and traversing a range of latitudes – visiting the Antarctic coast just once, at Mertz Glacier in East Antarctica.

By spending three months completing a full circuit of the ocean, we will be able to collect an unprecedented set of samples and measurements, which will greatly improve our understanding of the Southern Ocean.

Productive research

My research is concerned with phytoplankton – microscopic algae that live in the sunlit surface layer of the oceans. Just like plants on land, phytoplankton in the oceans photosynthesise, using the energy from sunlight to “fix” carbon dioxide into organic biomass, producing oxygen as a by-product. The rate of this change in biomass is called primary productivity.

Phytoplankton primary production forms the base of marine food webs, making it a fundamental process of marine ecosystem dynamics and directly relevant to fishery yields.

It is also an important component of the carbon cycle, and therefore global climate dynamics. This is because through a process called the “biological pump” a fraction of the roughly 45 billion tonnes of carbon fixed by phytoplankton every year sinks out of the surface layer and is stored in the deep ocean, away from the atmosphere.

My colleagues and I are trying to improve our understanding of what controls the distribution of phytoplankton, the rates of primary productivity, and the variability in the biological pump in the Southern Ocean.

Unfortunately, even sending a shipload of scientist on a three-month voyage to the Southern Ocean to measure phytoplankton biomass, productivity, and other chemical and physical factors, can only provide a snapshot of what is really going on. Ideally, we need to monitor the whole Southern Ocean over seasons, years, and decades. And this can actually be done, with the help of a technique called satellite ocean colour radiometry.

The main focus of our research is the collection of so-called “bio-optical” data, which will improve our ability to interpret satellite observations and derive better estimates of phytoplankton biomass and productivity in the Southern Ocean. This, in turn, will allow us to use past satellite records to determine how phytoplankton biomass and productivity has changed over the past decades, and help to establish possible connections to ongoing climate change.

It also means that we will be able to use satellite data to monitor, essentially in real time, what is happening to phytoplankton biomass and productivity in the Southern Ocean, without having to rely on frequent and extensive expeditions. But in the meantime, I’ll be more than happy to be part of this adventure.

Mediterranean ecosystems will change to a state unprecedented in the past 10,000 years unless temperature rises are held to within 1.5C, say scientists

Southern Spain will be reduced to desert by the end of the century if the current rate of greenhouse gas emissions continue unchecked, researchers have warned.

Anything less than extremely ambitious and politically unlikely carbon emissions cuts will see ecosystems in the Mediterranean change to a state unprecedented in the past 10 millennia, they said.

Research using miniature tracking devices suggests that swifts eat and sleep in the sky, as some birds did not land at all during their migratory period

Swifts already hold the title of the fastest fliers on Earth and now the small soot-brown birds have been revealed as one of nature’s greatest endurance athletes, after scientists discovered they spend ten months of the year entirely airborne.

Using miniature trackers, scientists observed that some birds did not land once during their migratory period, suggesting that they eat and sleep in the sky.

Move would also cut Scottish whiting catches to zero, while Celtic cod and Irish sole face hefty reductions to prevent stocks collapsing

The European commission has proposed closures on commercial fishing for sea bass in the Atlantic and whiting in the waters west of Scotland from next year, in order to prevent a collapse in fish stocks.

The total allowable catch (TAC) for cod in the Celtic Sea will also be cut by 68% under the plan, while sole quotas in the Irish Sea will be trimmed by a hefty 82%.

Americans must prevail on President Obama to establish a national monument around Grand Canyon National Park before we lose this historic chance

In 1967, my father took me and eight of my brothers and sisters on a whitewater trip down the Colorado River through Grand Canyon National Park. We camped on its massive sandbars, swam in its silty waters and explored the ancient geology of this iconic American landscape. He wanted us to experience the river and to understand the benefits that stem from our nation’s commitment to protecting its inspiring natural treasures.

I had these ideas in mind when I took my own daughter, Kick, down the Grand Canyon 40 years later, in 2007. We joined my old friend, the great anthropologist Wade Davis, and his daughter Tara. Davis was working on a book, and the four of us were guests of Imax cinematographer Greg MacGillivray, who released his film about our journey, Grand Canyon Adventure: River At Risk, in 2008.

Two-thirds of wild animals could be lost by 2020 and the biggest driver is destruction of their homes. A radical idea to give animals a ‘voice’ could encourage land managers to think about wild areas in a new way

Researchers report that the future for the Earth’s wild animals is very bleak. Two-thirds will be wiped out by 2020. While poaching is partially responsible, the biggest threat to wild animals is our impact on their homes – we kill them when we destroy forests and pollute waterways in the name of development.

Judging by the dramatic decline in the number of wild animals, it is safe to say that existing policy responses are proving ineffective. What’s needed is a fundamental change in how we view wild areas, and the policy responses to match.
