Why vegetarians should go for greenpower

One of my workmates is a strict vegetarian. Despite loving the taste of meat, she won't eat it. Like many people, she would feel bad about killing an animal herself. For her, it's equally bad if someone else does the killing for her.

Perhaps the only factor enabling many people to continue eating meat is that picking up a supermarket product or some fast food is so disconnected from the slaughterhouse floor.

switching to greenpower

I wondered if the same is true for electricity from fossil fuels. The acts of watching TV, running the fridge, or having a hot shower are psychologically separated from the coal and gas burnt to make the energy.

Just as many people would never want to kill an animal, I'm sure many people don't want to pollute the air and contribute to climate change. But our actions do just that, when using 'normal' electricity.

Just as vegetarians joins the dots, and switch away from meats, I hope we all join the dots on electricity, and subscribe to greenpower.

How to defeat your own argument

A politician here in Australia has tried to downplay the link between climate change and increased bushfire. He described fires as part of living in Australia, and not a function of climate change.

On what basis? Because we've had them before. As Graham Readfern points out, that's like saying that cigarettes don't kill people, because people still died before cigarettes were invented.

But the clincher was the list of previous fires given by the same politician. The 1850s, 1939, 1968, 1983, 1994, 2001, 2009 (and now 2013). Look at the maths - in particular the gaps between those years. 80-plus, then 29, 15, 11, 7, 8, and now 4 years. This is precisely the point that climate scientists make. These events get more and more frequent as we continue to heat the planet.

It's a compelling point. Just not one that this politician intended to make.

What keeps scientists up at night?

We hear about what the science says on climate change. But what about the scientists? What do they think? What keeps them up at night?

This video lets us hear from scientists - unscripted and talking about what matters to them. Their work and their concern for everyone.



It's refreshing to hear the personal reflections, even the emotional difficulties of working in an area studying the potential human impacts - or feeling sorry to their kids for not leaving them a better world. Thanks Climate Institute for putting this together.

A Bully with a Brick

You probably already know about the tragic bushfires in New South Wales, that have already claimed 193 homes.


Meanwhile, Adam Bandt has drawn some controversy for linking the bushfires to global warming. Clearly he's right - scientists agree. But some say it's not the right time to say so. But I agree with the person who said that's "like watching a bully smack someone in the head with a brick and saying 'Please don't talk about the bully now, it's disrespectful to the poor person with the headache.'"

Bandt quotes Ronald Reagan "The first duty of a government is to protect its people", and encourages "action to protect Australians from this kind of disaster and tragedy in the future".

Adam Bandt talking bushfires and global warming

Bandt doesn't want "every summer (let alone every spring) to be worrying about whether we are going to see these kind of bushfires again". But this is what scientists, and firefighters, have been warning Australia to expect from global warming. If we don't get global warming under control, the forecasts are for fires like 'Black Saturday' to happen about once every two years in Victoria. And that doesn't include the rest of the country.

firefighters union wants action on climate change

Meanwhile, the government this week announced legislation to remove Australia's main policy to reduce greenhouse emissions - the carbon price. Now that's bad timing. While the government talk about the financial savings of doing that, they don't talk much about the other costs of climate change. Like losing your home in a bushfire.

World Solar Challenge 2013

This solar car Darwin-to-Adelaide race is held every 2 years in Australia. What excites me is that rules get tougher each time, as the cars improve. They are looking less like science experiments, and more like everyday, usable cars.

For those interested in the race, the Nuon team of the Netherlands looks like the favourite to win it. The live race map, photos and more are at worldsolarchallenge.org.

What does it mean for Australia?

The latest climate change report is out, as I wrote on Monday. But what does it mean for Australia?

The hottest days will be up to 6 degrees hotter (remember Sydney was already 46°C last summer). Increased sea level rise could affect our coastal cities, and increased flood and drought will be bad news for agricultural areas.


During the release of the report, some prominent scientists had some comments about the effects for Australia:

"I am concerned about the unabated increase in upper ocean heat content reported by the IPCC. This is of particular relevance for eastern Australia where heat stored in the upper ocean has contributed to the major extreme rainfall and Queensland flood events during the summers of 2011 and 2012.

With a large population living close to the coast in Australia it is a real worry that sea level estimates have been revised upwards in the current IPCC Report – and their estimate is on the conservative side. This means we need a major rethink of how we manage, use, and develop our coastal communities and cities."
Dr Helen McGregor, University of Wollongong

"For Australia, this ratio (of more warm records, fewer cold ones) has been noted for decades."
Dr Julie Arblaster, Bureau of Meteorology (BoM)

"This is really going to be crucial to Australia's future. We're looking at impacts in Australia that are going to be at least as bad as other places because Australia sits at a range of latitudes that are expected to dry out as a result of a warmer climate. We tend to live on the coasts and sea levels are going to keep rising, and it's also a country that experiences extremes of heat."
Professor Steven Sherwood

Yes - The Hottest September Ever

It's official. September 2013 was Australia's hottest September on record (breaking the 2005 record). That also means the last 12 months is the hottest 12-month period on record (breaking the record from earlier this year).

heat map of Australia in Septemeber 2013

On a 1-10 scale orange areas indicate a 10, and dark orange indicates hottest on record. Obviously, a number of states also set records.

Combined with our hottest summer ever (particularly in January) and a very warm winter, it looks like 2013 could also be Australia's hottest calendar year. Surely it's time to do something about this.

PS. It turns out that my colleague and I were both right.

Time after time

I had a bit of a deja vu moment while writing yesterday's piece. This cartoon by Kudelka might help explain why.


Hopefully, for our own sake, we really start listening soon.
