Another 589 scientists speak out against Abbott’s war on the environment

22 07 2014

ATBC_logo_largeI’m currently in Cairns at the Association for Tropical Biology and Conservation‘s Annual Conference where scientists from all over the world have amassed for get the latest on tropical ecology and conservation. Unfortunately, all of them have arrived in an Australia different to the one they knew or admired from afar. The environmental devastation unleashed by the stupid policies of the Abbottoir government has attracted the attention and ire of some of the world’s top scientists. This is what they have to say about it (with a little help from me):

ASSOCIATION FOR TROPICAL BIOLOGY AND CONSERVATION

RESOLUTION IN SUPPORT OF STRONGER LAWS FOR CLIMATE-CHANGE MITIGATION AND ENVIRONMENTAL PROTECTION IN AUSTRALIA

Australia has many trees, amphibians, and reptiles that are unique, being found nowhere else on Earth. Northern Australia contains a disproportionate amount of this biodiversity which occurs in little developed areas, parks and reserves, indigenous titled lands, and community-managed lands.

Whilst Australia’s achievements in protecting some of its remaining native forests, wildlife and wilderness are applauded, some 6 million hectares of forest have been lost since 2000. Existing forest protection will be undermined by weak climate change legislation, and poorly regulated agricultural and urban development.

The Association for Tropical Biology and Conservation (ATBC), the world’s largest organisation dedicated to the study and conservation of tropical ecosystems, is concerned about recent changes in Australia’s environmental regulations, reduced funding for scientific and environmental research, and support for governmental and civil society organisations concerned with the environment.

Corporate wolves posing as environmental sheep

10 06 2014

wolf sheepA slicing article by Bill Laurance (incidentally, he will be speaking at The University of Adelaide on 26 June). Originally published in The Ecologist.

What do the Australian Environment Foundation, the Renewable Energy Foundation and the Global Warming Policy Foundation have in common? They are all fiercely anti-environment – and we must beware their ‘eco-doublespeak’.

George Orwell would have appreciated the Australian Environment Foundation. That’s because Orwell was a master of doublespeak – where words take on purposely obscure or opposite meanings.

Despite its name, the Australian Environment Foundation is not pro-environment. In fact, I consider it anti-environment, at least by the prevailing definition of that term.

For instance, the AEF opposes wind farms, many mainstream efforts to combat climate change, and what it labels “green thuggery” – such as initiatives to make cattle ranching more environmentally benign via the Global Roundtable for Sustainable Beef.

World Heritage Sites – who needs them?

In Australia, the AEF likes the Tony Abbott government’s efforts to remove World Heritage listing for 74,000 hectares of native forests in the Tasmania Wilderness World Heritage Area, to promote industrial logging.

In fact, the AEF likes it so much that it’s written to all of the members of the 21-nation World Heritage Committee, urging them to back the government’s bid when they consider it in Doha, Qatar this month.

If the government is successful, it will only be the second time in history that a natural World Heritage site has been de-listed.

A recent director of the AEF is Alan Oxley, an industrial lobbyist and former Australian trade ambassador who’s spearheaded opposition to numerous environmental initiatives around the world. Read the rest of this entry »





A convenient truth: global push for carbon-based conservation

19 05 2014

Eucalyptus viminalis (Manna Gum) - leaf, adultI’ve just written an article for the Australian River Restoration Centre‘s RipRap magazine, and they have given me permission to reproduce it here.

The brave, new green world of the carbon economy hasn’t exactly taken off as desired. Perhaps it’s because it wasn’t really planned from the outset, or maybe it is still too abstract for most people to accept, digest and incorporate into their daily lives. An emergent property of society’s generally slow awakening to the challenge of climate disruption, is that it will be a long time before we accept its full suite of incarnations.

The infant carbon economy is, however, well and truly alive and kicking, so it is important to try and plan for its growing influence on our decision making. Bumps in the road aside, the carbon economy has mostly been a blessing (actual and potential) for biodiversity conservation projects the world over.

In principle, the aim of the carbon economy is rather straight-forward: charge people a certain amount for each unit of carbon dioxide equivalents they release, and then use that money to develop approaches that further increase carbon sequestration or limit emissions. It’s a ‘build-it-and-they-will-come’ framework, where increasing financial impetus to restrict emissions is enhanced by society’s evolution towards better approaches and technology.

The operational side of the carbon economy is unfortunately much more muddled, with vested interests and political gaming weakening its implementation. Nonetheless, we persevere. Read the rest of this entry »

Eye on the taiga

24 03 2014

boreal damageDun! Dun, dun, dun! Dun, dun, dun! Dun, dun, daaaaah!

I’ve waited nearly two years to do that, with possibly our best title yet for a peer-reviewed paper: Eye on the taiga: removing global policy impediments to safeguard the boreal forest (recently published online in Conservation Letters).

Of course, the paper has nothing to do with cheesy Eighties music, underdog boxers or even tigers, but it does highlight an important oversight in world carbon politics. The boreal forest (also known as taiga from the Russian) spans much of the land mass of the Northern Hemisphere and represents approximately one quarter of the entire planet’s forests. As a result, this massive forest contains more than 35% of all terrestrially bound carbon (below and above ground). One doesn’t require much more information to come to the conclusion that this massive second lung of the planet (considering the Amazon the first lung) is a vital component of the world’s carbon cycle, and temperate biodiversity.

The boreal forest has been largely expanding since the retreat of the glaciers following the Last Glacial Maximum about 20,000 years ago, which means that its slow progression northward has produced a net carbon sink (i.e., it takes up more atmospheric carbon that it releases from decomposition). However, recent evidence suggests that due to a combination of increased deforestation, fire from both human encroachment and climate change, mass outbreaks of tree-killing insects and permafrost melting, the boreal forest is tipping towards becoming a net carbon source (i.e., emitting more carbon into the atmosphere than it takes up from photosynthesis). This is not a good thing for the world’s carbon cycle, because it means yet another positive feedback that will exacerbate the rapid warming of the planet. Read the rest of this entry »

You know it’s hot when it’s too hot to ….

My post’s title might be a good candidate title for a punk song in the 2030s (maybe by a re-incarnation of the Dead Kennedys).

I am currently sitting under my solar-powered ceiling fan as Adelaide is declared the world’s hottest city (and not in the funky, cultural, fun way), and I can’t help but contemplate climate change models predicting the fate of biodiversity over the coming decades. Because it’s far, far too hot to work outside, I’m perusing the latest interesting articles on the subject and I came across this recent little gem.

Also recommended on F1000Prime by Ary Hoffman, the paper, Using physiology to predict the responses of ants to climatic warming, by Sarah Diamond and colleagues touches on many aspects of climate predictions that need to be considered. I summarise these briefly here.

While no physiologist, I have dabbled in the past, although up until quite recently I didn’t see that physiology per se had much to do with conservation. It turns out that climate change has spawned an entire sub-discipline called ‘conservation physiology‘, which focuses inter alia on how species can/will/might respond and adapt to a warmer, climatically disrupted world.

What struck me about Diamond & colleagues’ paper was that yet again, it’s not as simple as heat-stressing a species experimentally and making a prediction on its future distribution (ecology is complex). No, the complexity comes in various forms that makes each species a little different from each other. Using North American ant species subjected to various warming scenarios in large (5 m) enclosures, they found the following: Read the rest of this entry »
