Guest Post by Geoff Russell. Geoff is a mathematician and computer programmer and is a member of Animal Liberation SA. His recently published book is CSIRO Perfidy. ———————————- There’s a gross cognitive dissonance when a Government who professes to think that climate change is the defining issue of our generation can’t face down a few blustering […]

Summer 2009 — 2010 hasn’t even begun in Australia, and yet we are already sweltering under another record heat wave — the third in two years. Temperature records for the month of November have been broken across the region, caused by a blocking high pressure system over the Tasman Sea. This follows an abnormally hot […]

Okay, so the title of this blog post is rather cryptic, but that’s because I want to quickly talk about three different things. Twittering BNC. Brook v Plimer report back. And the famous disappearing Arctic sea ice. First then, BraveNewClimate is now producing tweets. You can start following here: http://twitter.com/BraveNewClimate. I’ve also fed the latest […]

My scientific colleague and regular collaborator, Corey Bradshaw of ConservationBytes, has been hitting the media this week to talk about mosquitoes, models and environmental change. Together with our postdoctoral researcher Guojing Yang, we’ve published a couple of papers on the population dynamics of mossies in northern Australia. The latest one has just appeared in the […]

A long-standing research interest of mine has been the impact of prehistoric people and palaeoclimate on ancient biota (animals, plants, ecosystems). Millennia before the modern biodiversity crisis — a worldwide event being driven by the multiple impacts of anthropogenic global change — a mass extinction of large-bodied fauna occurred. These end-Quaternary (late Pleistocene and Holocene) extinctions […]

Climate change is like a stalking predator, a threat that first crept up, and then swiftly leapt out at the ecological science community. There is no doubt it was an issue around which there was a simmering awareness for decades. However, recent detailed multidisciplinary studies, which have pored over numerous long-term datasets (most compiled for […]

Guest Post by Tim Kelly. Tim is works as a Principal Climate Change Advisor in the Water Industry. The Federal Government has now released its Carbon Pollution Reduction Scheme White Paper and as expected the mechanism it has chosen is that of a pollution permit and trade system (cap and trade). The cap and trade […]

The Australian Bureau of Meteorology (BOM) has released a detailed analysis of the 2009 southern Australian heatwave. Some of the figures presented are staggering, with numerous temperature records smashed. Indeed, a colleague at BOM pointed out just how exceptional this event was: “Given that this was the hottest day on record on top of the […]

Adelaide is the hot place to be right now. We’re in the middle of an extreme, enduring heatwave, and the city’s residents are suffering. Indeed, we’ve had rolling blackouts as the power system fails to meet peaking loads, and more people are suspected to have died from heat stress over the last week than were […]

I haven’t talked a lot about marine impacts of climate change on this website — mostly because it is quite thoroughly covered by Prof Ove Hoegh-Guldberg in his Climate Shifts blog and Dr Simon Donner on Maribo. But in short, the marine environment is under severe stress from chronic human impacts (over-fishing, dredging, pollution [e.g., […]

In Part II, Hansen looks at policy options required to drag us out of the Sustainability Emergency. It is self-explanatory, but I thought it worth adding some notes on a cap-and-trade versus a carbon tax. Which is better? Cap-and-Trade. Pros: (i) Cap reductions ensure falling emissions – in theory; (ii) Reduces inefficiencies or overpricing; (iii) […]

Guest Post by Geoff Russell. Geoff is a mathematician and computer programmer and is a member of Animal Liberation SA. ———————— Late in 2006 the United Nations Food and Agriculture organisation published one of those huge thick reports that gets a one column story in quite a few newspapers and then vanishes from sight. It […]

The long-awaited, much-anticipated Final Report of the Garnaut Climate Change Review has now been released. As per its website, the review was set up to: “…examine the impacts of climate change on the Australian economy, and recommend medium to long-term policies and policy frameworks to improve the prospects for sustainable prosperity.” It is an independent […]

Guest Post by Tony Kevin. Tony Kevin served as an Australian diplomat in Moscow (1969–71), UN New York (1973-76), and as Australian Ambassador in Poland (1991–1994). This opinion piece was originally published in Eureka Street. Ross Garnaut’s important public statement was largely overwhelmed by the welter of federal and state political news. It was a […]

One of Australia’s leading authorities on the ramifications of climate change for human health and welfare is Prof Tony McMichael from the Australian National University. Earlier this year he and three co-authors published an important review in the British Medical Journal entitled “Global environmental change and health: impacts, inequalities, and the health sector” [full text […]

Records of abrupt climate events in the recent history of Earth suggest current emission reduction targets fall short of preventing carbon and ice/melt feedback loops and consequent runaway greenhouse effects Andrew Glikson (editing and hyperlinking by Barry Brook) Earth and paleo-climate research, Research School of Earth Science, Australian National University Summary: Current CO2 (carbon dioxide) […]

Solving climate change is a huge international challenge. Only a concerted global effort, involving the governments of all nations, will be enough to avert dangerous consequences. But that said, the individual actions of everyday people are still crucial. Large and complex issues, like climate change, are usually best tackled by breaking down the problem into […]

Jennifer Marohasy’s article in the Weekend Australian newspaper (23/8/2008) is yet another installment in the ongoing saga of Australian non-greenhouse theorists (‘sceptics’) attempting to discredit, at least in the eyes of the general public, the conclusions of Australian climate science. But one wonders why Institute for Public Affairs supporters choose to give their imprimatur to such […]
