Cool January saw a 1.6 degrees above average minimum temperature

20150205-BOM-Jan-Tmin-decile
Don’t be fooled by the cool January we have experienced, temperatures are warming up. Melbourne experienced it’s coldest January in 10 years despite the initial couple of extreme heat days at the start of the month. Although Melbourne’s average maximum temperature of 25.9 degrees was the same as the long term average, the average minimum temperature was 1.6 degrees higher than the long term average.

In previous years the average maximum temperature for Melbourne was 28.6 degrees in 2014, 27.3 in 2013 and 27.4 in 2012. The January average minimum temperature was 15.9 degrees, the lowest since 2005, and above the long-term average of 14.3 degrees.

Heatwaves and Victoria’s Heat Health Alert warning system

20150103--BOM-Max-temp-2Jan2015
As January maximum temperatures spike into the high 30s and low 40s (degrees Celsius) and minimum overnight temperatures approach 30 degrees, we have had our first Heat Health alert issued by the Victorian Department of Health for 2015.

On Friday 2 January 2015 heatwave conditions enveloped much of southeast Australia with temperatures reaching 43.3C in Adelaide and 38.7C in Melbourne.

Overnight temperatures on Friday night (2 January) hovered about 30 degrees in Melbourne and 24.5C in Adelaide. These minimum temperatures are more than enough to disrupt sleep adding to heat stress and associated heat-related health emergencies. (see Grunstein, Too Hot to Sleep? Here’s why, The Conversation, 8 January 2013).

Although Melbourne was predicted to exceed 40C on Saturday (3 January) the temperature only reached 37.7C at 3.30pm. That afternoon a storm front brought some rain and relief, a cool change plunging the mercury just before 6pm.

Moreland Council increases Heatwave response strategy

Days over 35 degrees C for Melbourne
As well as taking the lead with fossil fuel divestment, the other important climate change related item at Moreland Council meeting on 8 October 2014 was a tabling of a report on heatwave strategies including the feasability of council heatwave refuges. The report was initiated as a result of a resolution moved by Cr Bolton at the Council meeting in February 2014 (See my report: Moreland Council calls for greater heatwave emergency planning for Victoria).

Council Officers employed an outside consultant to prepare a discussion paper: Potential Risks and benefits of Different Responses to Heatwaves. The discussion paper was then used to write up a report with recommendations to Council.

Transport Forum question on Climate change and heatwaves

IMG_8522-600w
The Moreland Transport Forum was held on Monday, just a few hours after Premier Denis Napthine signed the East West Link contracts. A few of us from Climate Action Moreland attended handing out our leaflet on East West Link being Climate Madness, and a climate postcard.

Andrea Bunting from our group submitted the following question to be asked at the forum. It was the most highly rated question.

With climate change, we are facing a hotter, carbon-constrained world. Currently during heatwaves we can experience power failures for public transport, unbearable heat in trams and trains, and buckling of train tracks. Dark roads also amplify the urban heat island effect; hence temperatures in our urban areas are much hotter, leading to increased deaths and illness. What will you to do (a) reduce dependency on fossil fuel usage in transport; (b) ensure that all transport infrastructure can deal with heat waves; and (c) reduce urban heat island effect from dark roads?

The question was asked slightly differently in person at the forum to all three candidates – sitting member for Brunswick Jane Garrett MP, Greens candidate for Brunswick Tim Read, and Liberal Party no 2 on the ticket for Northern metro region (Upper house) Gladys Liu.

Victorian Premier warns 100,000 premises may lose power during extreme heatwave

20140115-Jacana-heatwave-electricity-transmission-DSC03741-w640

The Premier Denis Napthine warned Victorians that 100,000 premises may lose power during the extreme heatwave due to demand on the state’s electricity grid. Thank you Premier, for your incompetence at managing electricity generation in Victoria.

Climate scientists have been warning of the increased frequency and intensity of heatwaves, with a long term trend of increasing temperatures and 2013 being our hottest year on record. (See this 2009 study by Alexander and Arblaster – Assessing trends in observed and modelled climate extremes over Australia in relation to future projections (PDF))

Much of the electricity system is about managing peak demand through ensuring adequate generating capacity in the network. Victoria’s continued reliance on aging brown coal fired generators with impediments to diversification through renewables has let down the electors and residents of Victoria, badly. We are now seeing the results of poor climate and energy policy at the state level.
