Australia getting hotter – Climate Commission

The BOM's interactive weather chart has had new colours added to accomodate the record breaking heatwave, the result of AGW.

The BOM’s interactive weather chart has had new colours added to accomodate the record breaking heatwave, the result of AGW.

Australia was already a land of extremes but it’s hotter than before with a greater risk of more heatwaves and more severe weather. The Climate Commission says the length, extent and severity of the present heatwave is unprecedented and shows climate change is making extreme heat and bushfires worse.

It says the impact needs to be understood to plan for more of the same.

In a report called Off the charts: Extreme Australian summer heat, one of the authors, David Karoly, says the heatwave has affected over 70 per cent of Australia and longstanding temperature records have been broken.

“Although Australia has always had heatwaves, hot days and bushfires, climate change is increasing the risk of more frequent and longer heatwaves and more extreme hot days, as well as exacerbating bushfire conditions,” Professor Karoly said in a statement.

“The baseline conditions have shifted.

“We live in a hotter world and the rise of more frequent and severe extreme weather has already increased.”

The current conditions are unusual because of their widespread nature and duration, the report says.

Heat is a “silent killer” because small changes in the environment can have dramatic impact on the human body.

The report says if the core body temperature exceeds 38 degrees Celsius for several hours judgment and behaviour can be impaired.

Heatwaves in recent years have resulted in increased hospital admissions and death.

The Climate Commission says having a good understanding of climate change risks can ensure that action is taken to reduce greenhouse gas emissions and plans are made to respond to more extreme weather.

    I hear that Christopher Monckton’s core body temperature has been well above 38 degrees Celsius for years now and look what it’s done to his judgement and behaviour.

    It’s good to see such strong statements being published.

    incidentally, I’ve been seeing a resurgence of deniers on various sites in the past few days. I think the heat has badly affected them :(

    • Yep, what’s with that? A couple over at wtd are soooo stupid I actually miss Eric Worrall.

      Sou you have been putting out some top stuff, i think that you have found your calling, Local papers have been printing my stuff and even fixing up some of my typos,

      Speaking of heat affected, anthony cox still does not get the Knorr 2009 paper, @ TCS

        Thanks John – you overstate my talents but I must admit deniers are just too easy to send up!

        I’m tempted to pick up some of WUWT. When not engaged in ad homs or arguing ‘an ice age is coming’, they are busily engaged in convoluted / incomprehensible debates over whether ‘it’s the sun’ or ‘it’s ENSO’, determined to try to find a way to ‘prove’ that all this extra heat is not from the obvious culprit – the increase in greenhouse gases.
