Apocalypse Not: doomsday thinkers of Oz should get out more

I sometimes wonder what planet this country of ours is on. The environmental debate we are having seems to be in a parallel universe to the rest of the world. Having spent the last four years running one…
Australians generally accept that the climate is changing, but we have lost confidence in politicians, experts, and the media to guide us in what to do about it. Flickr/spodzone

Reading the Climate of the Nation 2012

Over the past several decades, scientists have studied the climate of the world and how that is changing. These studies have built on the recognition, made over 150 years ago by John Tindall, that certain…
Tree rings from around the time of Christ suggest warmer regional temperatures than those between the 1950s to the 1980s, but this does not imply higher mean global temperatures. Flickr/Petrified Forest Ranger

On tree rings, CO2 levels and the Pliocene

A study of tree-ring data recently found that in some regions temperatures during Roman times (21AD to 50AD) were 1.05 degrees Celsius higher than the 1951-1980 mean. The paper’s lead author, Professor…

2011 to be remembered as the year of extreme weather

Severe droughts, floods and landslides devastated parts of the world last year as carbon dioxide concentrations climbed to…
Herbarium specimens of leaves from the Narrow-leaf hopbush are 40% wider than contemporary specimens. Greg Guerin, Haixia Wen, Andrew Lowe

Climate change linked to narrowing leaves

Climate change is causing the leaves of at least one subspecies of Australian plant to narrow in size, a team from the University…
Scientists have a better understanding of the contribution of melting glacier and ice sheets to sea level rise, but much remains uncertain. Flickr/ChrisGoldNY

Melting ice the greatest factor in rising sea levels

Melting glaciers and ice sheets have contributed more to rising sea levels in the past decade than expansion from warming…

Adapting to climate change: more questions than answers!

With increasing global greenhouse gas emissions, and no clear internationally-agreed path for emission reductions, we are faced with a global climate that will be at least two degrees warmer than today…
Natural records taken from coral, tree rings and ice cores helped to provide a “climate picture” for the past 1,000 years. AAP Image/ARC Centre of Excellence, Natalie Rosser

Post-1950s warming in region unmatched in 1,000 years

Update October 2012: The manuscript “Evidence of unusual late 20th century warming from an Australasian temperature reconstruction…
Scientists say the supply of freshwater in Australia could eventually be at risk. AAP/Linda Silmalis

Dry parts of the planet to get drier, wet parts wetter

The cycle of evaporation and rainfall over the past 50 years has intensified at twice the rate predicted by climate change…
Tiny humans would consume less and emit less, but who’s ready to genetically engineer their kids? Dylan Luder

No modest proposal: bioengineering humans for global warming

You know the situation is getting desperate when three bio-ethicists propose genetically modifying humans to reduce our environmental impact. In a bizarre paper titled Human engineering and climate change…
