Climate clippings_175These posts are intended to share information and ideas about climate change and hence act as a roundtable. Again, I do not want to spend time in comments rehashing whether human activity causes climate change.

This edition is mainly about politics and policy rather than the science.

1. Anti renewables tirade

As the forces of darkness are unleashed upon us under the rule of Tony Abbott, people attending the Eastern Australian Energy Outlook Conference were subjected to a “venomous rant” against the renewable energy target from Burchell Wilson, a senior economist at the Australian Chamber of Commerce and Industry.

The tragedy of this is that Wilson’s presentation may have been plain wrong, nasty, manipulative and ideological, but he’s not alone in Canberra….

As Wilson (rightly) pointed out, there is a vast reserve of anti-renewables passion in the rump of the National Party and the Liberal party backbench open to such rhetoric– which insiders say is being whipped up by new Liberal MP Angus Taylor.

Wilson expressed his hope that these views would overwhelm those of moderates such as Environment Minister Greg Hunt, and Energy Minister Ian Macfarlane. He hoped that the economic rationalists at the Productivity Commission would have carriage of the next RET review.

2. Mining lobby targets RET

In the current political climate the RET is under serious threat, being targeted directly by the mining industry.

This is how John D sees it:

Australia’s RET is one of the few emission trading schemes in the world that is actually working. For years it has been steadily driving investment in utility scale renewables. Better still, because it is an offset credit trading scheme that does not generate government revenue it is achieving this with negligible changes in power costs. (The fossil power companies are actually complaining that it is pushing wholesale prices down!)

For this reason it is of some concern to see that the Minerals industry is pushing for the repeal of the RET.

We should all be campaigning for an increase in the RET target and against any attempt to eliminate or scale back the RET.

Climate clippings_175These posts are intended to share information and ideas about climate change and hence act as a roundtable. Again I do not want to spend time in comments rehashing whether human activity causes climate change.

This edition is mostly about the doings of our new government, prospective EU targets, a statement by religious leaders and a couple of items on health implications.

1. Greg Hunt’s role diminished

Whether or not Greg Hunt gets to go to the UNFCCC (UN Framework Convention on Climate Change) Conference of Parties (COP) in Warsaw from 11 to 22 November. Julie Bishop will henceforth be the lead negotiator in international climate talks.

The story in the AFR says Hunt has been “stripped of responsibility for global climate change negotiations”. He still gets to go and hang out at the talks. One might say that Australia’s representation has been upgraded. Suspicious minds might also think that Hunt couldn’t be trusted. He actually believes human activity causes global warming and might join the warmist urgers if not kept on a tight leash. Continue reading Climate clippings 84

Climate clippings_175These posts are intended to share information and ideas about climate change and hence act as an open thread. Again I do not want to spend time in comments rehashing whether human activity causes climate change.

This edition contains items, exclusively, I think, in climate science and impacts. The thread is meant to function also as a roundtable to share information and ideas.

1. Climate change picked the crops we eat today

The New Scientist carries a story about how some cereals we know today were changed by the climate as we came out of the last ice age. Researchers at the University of Sheffield, UK took seeds of precursors of modern wheat and barley found with human remains in a 23,000-year-old archaeological site in Israel. They grew these together with four wild grass species that aren’t eaten today, but were also known to grow in the region at that time, and grew them under conditions replicating levels of CO2 then and also the higher levels when farming first arose 10,000 years ago.

All the plants grew larger under the higher levels of CO2, but the relatives of wheat and barley grew twice as large and produced double the seeds. This suggests the species are especially sensitive to high levels of CO2, making them the best choice for cultivation after the last ice age.

The team plan to look at whether other food staples around the world are similarly affected by elevated CO2 levels, for example millet grown in Asia and maize in North America. They also plan to compare the effects of CO2 on legumes such as peas. Continue reading Climate clippings 83

Open thread on floods

We now have a number of specific threads running on aspects of the Queensland floods. This thread is for comments that don’t fit the specific threads or if you want to comment on other current floods lacking a thread, such as those in Victoria, Brazil or Sri Lanka .

These are the previous threads I can identify:

Brian on Queensland floods

Robert on Queensland floods get worse

Mark on Brisbane flood maps and up to date flood information

Brian on Toowoomba flood pics

Brian on Brisbane floods in retreat

Kim on Political cheap shots and the Brisbane floods

Kim on Quick link: Quiggin on water policy after the Queensland floods

Kim on Quicklink: Interactive map of Brisbane flood damage

Kim on Germaine Greer wrong on Brisbane floods

Mark on Social capital, social networking and the Brisbane floods

Hope I haven’t missed any.
