It’s been almost a year since Climate clippings 2. Shall I say that intentions are good now, as they always have been.
I have included a brief mention of a number of news items relating to climate change. It doesn’t preclude treating any of these topics at more length in a separate post.
It can also serve as an open thread so that we can keep each other informed of important climate news.
What percentage of global warming is due to human causes vs. natural causes?
Pretty much all of it, according NASA scientist, Gavin Schmidt. Prior to the industrial age we were on a cooling trend.
According to commenter Mike there is an easy answer to another question:
What percent of ocean acidification is natural? 0%
Don’t mention the famous piece of sporting equipment or a swarm of locusts will appear:
There is another view, of course. According to Adjunct Professor Carter this CO2 stuff is not just lost in the noise in causing global warming, it’s barely a blip in the error bar.
That was in response to Bob Ward, Policy and Communications Director of the Granthem Research Institute at the London School of Economics calling Carter’s article ” the worst that has ever been published about climate change”.
Michael Mann muses
Meanwhile Michael Mann muses on the lengths to which deniers will go, deniers, mind, not skeptics, in order to discredit a simple graph that tells a simple story, reminding us that other researchers have extended the graph further back in time, affirmed its shape, and that climate science relies on multiple lines of evidence. Minister for Science, Kim Carr, is more blunt:
We don’t have to accord superstition and wishful thinking the same status as science. This is much more than fairness requires and much more than reason permits.
That George Munster Award Forum is worth a listen, BTW.
Garnaut speaks out (again)
Garnaut goes for science-led action.
Action by scholars, to be precise, and not economists squabbling over minutiae and definitely not vested interests. Overall he said it was:
”unlikely that Australia will come to play its proportionate part in an adequate global effort [on climate change] unless there is a strong independent centre of our public life, that holds some ground for the public interest against the huge investments that will again be made in false information and the distortion of the political process”
But not direct action, I’m sure he would say. Gillard reaffirms her preference for a carbon price and tips buckets on Tones’ direct action approach.
Gillard won’t follow US carbon retreat
No she won’t. That’s what Michelle Grattan says.
Ms Gillard said: ”President Obama is defining a strategy to tackle climate change in the political circumstances that America finds itself in.
”We are great friends and allies of America, but we are not an American state. We are our own country – we will determine our own strategy,” she said.
It’s amazing what you find in the Queensland Country Life, owned by Fairfax.
Solar panel scheme a waste of money
ANU researchers Andrew Macintosh and Deb Wilkinson have found that
MORE than $1 billion of taxpayers’ money was wasted on subsidies for household solar roof panels that favoured the rich and did little to reduce Australia’s greenhouse gas emissions
They also found that “the rebates did little to generate a solar manufacturing industry in Australia, instead sending hundreds of millions of taxpayers’ dollars offshore.”
All solar panel systems installed under the program combined reduced Australia’s emissions by just 0.015 per cent, and cost up to $301 per tonne of carbon saved
Greenland is melting
Faster than ever, as reported by Climate Progress:
New calculations show that the amount of melted inland ice in Greenland is 25-50% higher in 2010 than normally.
That’s not new news, but it’s important. Sea level rise is emerging as an increasing concern over the 21st century as stressed by CSIRO oceanographer John Church.
Aggressive mitigation is the only real answer.
Is climate science disinformation a crime against humanity?
That’s the question asked by Donald Brown of Penn State University.
Deeply irresponsible corporate-sponsored programmes of disinformation have potentially harsh effects upon tens of millions of people
According to John Broder of the New York Times:
the fossil fuel industry has “created and lavishly financed institutes to produce anti-global warming studies, paid for rallies and websites to question the science, and generated scores of economic analyses that purport to show that policies to reduce emissions of climate-altering gases will have a devastating effect on jobs and the overall economy.”
It’s worth a lot to the oil and coal lobbies to get the Congress they want and the investment seems to be paying off
Biofuels may be worse than fossil fuels
EU plans to produce biofuels will cover land the size of the Republic of Ireland and will generate between 81 and 167 per cent more carbon dioxide than fossil fuels, according to a study by 9 NGOs. The concept of “indirect land-use change” claims that if you displace food production someone somewhere goes hungry or new land is cleared to grow the food.
The EU Commission emphasises the use of abandoned agricultural land, but the study says that actual plans by member states involve 90% food displacement.
But in Connecticut they think industrial hemp might be the answer.
Thanks to John D for the heads-up.
So far 2010 is the warmest year on record
NASA has done the sums for October. So far 2010 is the warmest year on the instrumental record. It’s shaping up as warmer than 1998 and will be line-ball with 2005. Please note:
it bears repeating that the record warmth we are seeing this year is all the more powerful evidence of human-caused warming “because it occurs when the recent minimum of solar irradiance is having its maximum cooling effect,”
Also the 12-month running mean global temperature has reached a new record in 2010 — despite recent minimum of solar irradiance:
“We conclude that global temperature continued to rise rapidly in the past decade” and “there has been no reduction in the global warming trend of 0.15-0.20°C/decade that began in the late 1970s.”
It’s perhaps worth mentioning that about a year ago I attended a lecture wherein Prof Carter showed a graph demonstrating that there had been no warming in the last 50 years.
Over to you.
