For coal I'll agree with you about the environmental residue, but

How can you possibly say that.?  What happens to the spent uranium.???
Sent into space perhaps?

Well it's certainly not buried at the site, or left lying around now is it??

Can you site an example of a decomissioned nuclear plant that was returned as residential or productive farm land ?

But the good thing about an abandoned wind farm is that the land is in as good a condition as it was (once you pull down the towers).

Compare that to an abandoned nuclear or coal generator where the land is left poisoned and unusable.


The problem is the cost of pulling down the towers though...(and a wind farm covers a much greater area than nuclear or coal power plants..)


Try telling that to the Japanese!

Climate catastrophe on our door step


The latest State of the Climate report by the Australian Bureau of Meteorology and the CSIRO was launched at a weather monitoring station on remote Cape Grim in Tasmania. The location was an apt choice for a report that has very bad news about Australia's continuing failure to respond adequately to the climate change crisis.

The report says each decade since the 1950s has been warmer. Annual-average daily mean temperatures have increased 0.9% since 1910 and annual-average overnight minimum temperatures have warmed by more than 1.1% since 1910. 

The recent two years of wetter weather, due to the La Nina effect, do not mean this long-term warming trend has ended. The report said last year “was the world’s 11th warmest year and the warmest year on record during a La Nina event”.

The world’s 13 warmest years on record have all been in the past 15 years.

La Nina is related to warmer-than-average ocean temperatures around Australia and sea-surface temperatures around Australia have risen faster than the global average, the report said.

The report projected an average temperature rise in Australia of 1-5ーC by 2070, long-term drying over southern and eastern Australia and more extreme weather such as floods, droughts and cyclones.

CSIRO research says an average temperature rise of just 1-2ーC would bleach 58-81% of the Great Barrier Reef each year. Core habitat for vertebrates in the northern tropics would drop 90%.

Three to four degrees would kill 95% of Great Barrier Reef species, shrink 20-85% of total snow-covered area in the Australian Alps and ruin 30–70% of core habitat for Victoria and highland tropical vertebrate species.


http://climatechangesocialchange.files.wordpress.com/2012/03/atmospheric-ghgs-by...

If average temperatures rise above 5°C, Australia will lose 90–100% of core habitat for most vertebrates.

The State of the Climate report said the global average sea level last year was 210mm above 1880 levels and rose faster between 1993 and 2011 than during the entire 20th century.

The report said greenhouse gases continue to rise exponentially. Carbon dioxide has reached 390 parts per million in the atmosphere.

No, not yet. Although there are three in the US that have been classified as 'greenfields' (ready to be used for housing/farming), pending removal of the last expended rods to storage facility....

Most of the reactors in the world are still in use, or in the early stages of the decommisioning process..

Warming world defies La Nina


CLIMATE change is accelerating, with least year the 11th-warmest year since records began in 1850, despite the cooling influence of La Nina, according to the World Meteorological Organisation.

Global average precipitation last year was the second-highest since 1901, with significant flooding on all continents, although parts of east Africa and North America experienced drought.

Arctic sea ice fell to near record-low levels and, while there was some respite from tropical cyclones, the US had one of its most destructive tornado seasons ever recorded.

Forty-eight of 102 countries reported new record maximum temperatures in the decade 2001-2010, compared to 20 per cent for the preceding decade and about 10 per cent for earlier decades.


The rate of global temperature increase for the four decades from 1971 to 2010 was at roughly double that for the 13 decades 1881 to 2010, a change the WMO described as "remarkable".

In an annual climate statement, released last night, the WMO said globally averaged temperatures last year were 0.4 degrees above the 1961-90 average of 14 degrees, despite one of the strongest La Nina events of the past 60 years. The Pacific coupled ocean-atmosphere phenomenon is typically associated with cooling.

"This 2011 annual assessment confirms the findings of the previous WMO annual statements that climate change is happening now and is not some distant future threat," said WMO Secretary-General Michel Jarraud.

Meanwhile, in its preliminary decadal climate statement, also released yesterday, the WMO said 2001-10 was the warmest decade since records began. The warmest year was 2010, closely followed by 2005.

Northern Australia and large parts of the northern hemisphere were wetter than average in the past decade, while southeastern Australia, the western US and some other areas were drier.

Virtually all parts of the world were affected by extreme weather events, although the WMO did not link these to climate change. Flooding was the most widespread, with historical, widespread and prolonged events affecting eastern Europe in 2001 and 2005, Africa in 2008, Asia -- in particular, Pakistan -- in 2010, India in 2005 and Australia in 2010.

Australia also reported extreme drought conditions, as did a number of other countries, including eastern Africa, the Amazonia region and the western US.

The North Atlantic basin saw its highest level on record of cyclone activity in the past decade, with hurricane Katrina its most severeevent. Cyclone Nargis was the deadliest, killing more than 70,000 people in Burma

U.S. heat 'unprecedented,' 7,000 records set or tied


(Reuters) - An "unprecedented" March heat wave in much of the continental United States has set or tied more than 7,000 high temperature records, and signals a warming climate, health and weather experts said on Friday.

While natural climate variability plays a major role, it is the addition of human-spurred climate change that makes this particular hot spell extraordinary, the scientists said in a telephone and web briefing.

"This heat wave is essentially unprecedented,"
said Heidi Cullen of the nonprofit science and communication organization Climate Central. "It's hard to grasp how massive and significant this is."

Since March 12, more than 7,000 high temperature records have been equaled or exceeded, Cullen said, citing figures from the U.S. National Climatic Data Center (here).

These records include daytime high temperatures and record-high low temperatures overnight, which in some cases are higher than previous record highs for the day, Cullen said.

"When low temperatures are breaking previous record highs, that's when you see this is incredibly special," she said.

"Most likely the weird weather arises from natural variation on top of a warming climate," said Michael Oppenheimer, a geoscientist at Princeton and a veteran participant in the Intergovernmental Panel on Climate Change. "What we're seeing now is not surprising in the greenhouse world ... It's just the beginning of our experience with the new atmosphere."

Oppenheimer was a lead author of the panel's path-breaking 2007 report that analyzed research by hundreds of scientists and found there was a 90 percent probability that climate change is occurring and human activities contribute to it.

That report projected an increase in heat waves, droughts, floods, severe storms and extreme temperatures as a result of human-spurred global warming, caused in part by rising emissions of greenhouse gases, including carbon dioxide emitted by fossil fuel burning.

There's the good news AND there's the bad news.

The Good news is, Peak Fossil Energy will reduce GHG's over the next 20-30 years and that MAY mitigate the worst of the effects of Climate Change on the Global Environment?

The Bad news is, Peak Fossil Energy will ensure the Global Economy takes a massive hit over the next 20-30 years, as the COST OF ENERGY takes an increasing ratio of Global GDP, which will exacerbate a REDUCTION in DEMAND for GOODS & SERVICES, which are already set to head lower due to DEMOGRAPHIC ISSUES involving the Baby Boomer generation, who will first retire then leave us forever, in ever increasing numbers, also over the next 20-30 years!

I agree that climate change is a problem and we should do something about it. I can no longer read these reports though, because nothing will be done. Moment a good idea leads to someone losing a single dollar anything will be thrown up as an excuse to kill it. Doesn't matter what the excuse is, anything will do for a scrooge faking denial.

That's a very fair comment. The problem is that what you describe is a very short sighted attitude, because in the long run it's going to cost a mint.

Apart from that, they don't take up a lot of land in relative terms.  The same argument could be made with regards to coal fired power stations. In fact the huge quantities of fly ash does a lot more damage.

I understand where that statement comes from and there is a segment of the Public, plus Politicians & vested interests who push that perspective, in an attempt to maintain the status quo.

Unfortunately, over time, maintaining the status quo is simply not possible!

In any event, there are costs & benefits involved, no matter what actions OR lack thereof are taken and over time the Economic losses involved of taking action to mitigate the worst effects of Climate Change, will be far less than the Economic losses involved by not taking mitigating actions!

When the worst effects hit people they will just use the actual hardship as an excuse to clam up and do nothing. Just like they use the imagined hardship (real in some cases though) of bothering to do anything about the environment right now.

Study: Global temperatures could rise 5 degrees by 2050


As the USA simmers through its hottest March on record — with more than 6,000 record high temperatures already set this month — a new study released Sunday shows that average global temperatures could climb 2.5 to 5.4 degrees by 2050 if greenhouse gas emissions continue unabated.

The study findings are based on the results of 10,000 computer model simulations of future weather overseen by researchers at Oxford University in the United Kingdom.

"These are the first results to suggest that the higher warming scenario could be plausible," says study lead author Dan Rowlands of Oxford.

It is a faster rate of warming than most other models predict.

Most scientists say that increasing amounts of carbon dioxide in the atmosphere from the burning of fossil fuels such as oil, gas and coal are causing the planet to warm to levels that cannot be explained by natural variability.

The study was published online Sunday in the journal Nature Geoscience and backs up similar predictions from the Intergovernmental Panel on Climate Change in 2007.

According to Rowlands, the climate model was the most complex used to date, and addresses some of the uncertainties that previous forecasts, using simpler models, may have overlooked.

"It's only by running such a large number of simulations — with model versions deliberately chosen to display a range of behavior — that you can get a handle on the uncertainty present in a complex system such as our climate," says Rowlands.

The climate models used in the study accurately reproduced actual, observed temperature changes over the last 50 years: Assuming that models that simulate past warming realistically are the best candidates for future warming predictions, the authors conclude in the study that a warming of from 2.5 to 5.4 degrees by 2050, compared with the 1960-90 average, is in the "likely range" of climate warming.

The earth's average temperature during the decade of 2000-2010 was almost a full degree higher than the average from 1960-90, Rowlands says.

The project ran almost 10,000 climate simulations on volunteers' home computers, which was made possible because volunteers donated time to run the simulations on their home computers through climateprediction.net, as part of the BBC Climate Change Experiment.

"Perhaps the most ambitious effort to date, this work illustrates how the citizen science movement is making an important contribution to this field," says paper co-author Ben Booth, a senior climate scientist with the U.K. Met Office's Hadley Centre.
