Ward off Climate Change

About the author


Gary Warden was raised in the Perth Hills. After graduating from the University of Western Australia with a degree in Geology, Gary joined BHP Billiton where he spent 18 years working in a variety of roles in a number of locations around the world. Prior to leaving BHP Billiton in December 2006, Gary was Global Manager for the company's US$1Billion business improvement program.

While he was originally sceptical about the claims relating to climate change, he became convinced of the urgency of the issue in early 2006. He left BHP Billiton primarily to spend more time with his young family, but also to dedicate himself to creating a more sustainable life for himself and his family and to support others in making that change.

In September 2007 he was trained by Al Gore and has delivered the "Inconvenient Truth" lectures to thousands of west australians since then. In November 2007 Gary ran for the senate in the Federal Election representing the Climate Change Coalition.

In addition to his climate change lectures, he has facilitated Living Smart workshops across Perth. Between 2008 and 2009 he was on the Executive Committee of the Conservation Council of Western Australia including one year as Vice President.

Gary co-founded and is Executive Director of the very exciting Days of Change program, one of the largest sustainability programs in Australia and is now General Manager WA for Eco-Kinetics, one of the largest Solar PV companies in Australia and subsidiary of ASX-listed CBD Energy.

Helen (Australia), Ursula (Papua New Guinea), Sahena (Bangladesh), Muriel (Brazil), Melissa (UK) and Martina (Uganda) live on different sides of the planet, but are united against climate change. Oxfam has produced six short films that tells the amazing stories of these women and is screening them on Wednesday March 4 from 5:30pm to 7:30pm at the Alexander Libary.

See the invitation below for more details.

Climate Change the Focus on Lateline

by Gary 2/24/2009 8:51:00 AM

 Last night's Lateline program on ABC TV featured a number of fascinating stories on climate change. 

The first story highlighted the latest science of climate change that shows that the effects of increasing levels of greenhouse gases are exceeding even the worst case scenarios presented by the IPCC, including the alarming melting of the Greenland ice sheet.

http://www.abc.net.au/lateline/content/2008/s2499388.htm

Andrew Robb, the Coalition spokesperson on Emissions Trading joined the program and explained the Coalition's position on an ETS. The Coalition believes that it can set a target above the government's 5% target for emissions reductions by 2020, but is unwilling to specify exactly what their target is.

Bob Brown from the Greens then explained the Greens' postion on an ETS, saying that they believed that a target of 40% was required to avoid cataclysmic climate change given the alarming news presented by the scientists.

Aquaponics Producing a Rich Bounty

by Gary 2/23/2009 8:22:00 PM

Towards the end of 2007, we used Joel Malcom and Faye Arcaro from Backyard Aquaponics to install a large aquaponics system adjacent to our house in Piesse Brook.

The system consists of six large grow beds, a small sump tank and a large 3000 litre fish tank. It took us a while to get the system set up right. For example, initially we stocked the tank with just 25 Silver Perch. We found that this stocking level didn't produce enough effluent from the fish to supply the grow beds with enough fertiliser for the plants to grow effectively.

Since adding an additional 125 Silver Perch, we haven't looked back. The vegetables have been growing like crazy and we've now successfully harvested lettuce, spinach, tomatoes, cucumbers, zucchini, beetroot, spring onions, celery, artichokes and capsicums in the grow beds.

The fish are also now plate size and ready for harvesting. 

The system is large enough to provide a large proportion of our fish and vegetable needs.

One of the great things of this approach, is that it uses just 10% of the water of traditional vegetable growing methods. So in an increasingly dry climate, this is a great way to go. The only downside is that the pumps do require electricity to run, however we have 2kW of solar PV panels being installed tomorrow, so this will help us run those pumps free of emissions.

Check Out This Video - Garbage Warrior

by Gary 2/22/2009 8:54:00 PM

Toni and I found a new release movie entitled "Garbage Warrior" in our local video store.

The movie tells the story of Michael Reynolds who for 30 years has been on a crusade to build self-sufficient, sustainable homes from what most people would consider garbage - used tyres, drink bottles and cans.

It includes his efforts to overcome archaic planning laws in his home state of New Mexico and his inspirational work helping survivors of the Boxing Day tsunami build new homes.

Check it out at your local video store, however here is a taste of the movie.

Tip of the Week

Changes to Federal Government Solar Rebate

by Gary 2/10/2009 5:59:00 AM

I’ve got good new and bad news.

The good news for those of you who don’t currently qualify for the $8,000 solar rebate from the Federal Government because your household income is above $100,000, is that from July 1 this year the $100,000 means test is to be scrapped.

The bad news is that the new scheme is horribly complex, and it is impossible to predict exactly how much the rebate will be as the value of it will be tied in with the Renewable Energy Target Scheme and will therefore vary.

What is certain is that households earning less than $100,000 will also get less assistance under the new scheme.

For example, under the current scheme, a household earning less than $100,000 can install a 1kW system and receive a $8,000 from the federal government.

Under the new scheme starting in July 1, the same household will receive as little as $4,500. To receive the maximum rebate, the household will have to install a much more expensive 1.5kW system, in which case a rebate of approximately $7,500 will apply.

Households earning more than $100,000 will be the big winners, going from receiving no rebate under the current means test, to receiving the same rebate as lower income households as described above.

So what should YOU do?

If your household income (total income less allowable tax deductions) is less than $100,000, then you should move quickly to sign-up for panels before July 1. If you wait until after July 1, you will lose up to  $3,500 in rebates compare to the current system.

If your household income is above $100,000, then you are probably better off waiting until July 1 to sign up for your system.
