The following articles claim UVB (ultraviolet radiation in the 270-320 nanometer [nm] band) had been the only/main suspect in causing skin cancer but that is really quite wrong. This assertion appeared in 2004 and represented a paradigm change. (links in our ozone page)
UVA (320-400nm) is and has always been the prime suspect in deep tissue penetration and genetic damage leading to melanoma while UVB, which can cause sunburns, has always been (and still is) otherwise considered benign/beneficial. UVC (<270nm), which would cause severe burns with short exposure but does not penetrate the atmosphere, blocked completely by atmospheric oxygen (O2) in addition to ozone (O3).
The only reason we can find for the reversal of paradigm and “villain switch” is that UVA is not blocked by stratospheric ozone at all and made a lie of claims that alleged stratospheric “ozone depletion” would lead to an increase in skin cancers. UVB is blocked to some extent by ozone (and thick cloud) and thus had to be made the villain of the narrative.
The claim that stratospheric ozone creates some sort of “life shield” around planet earth is and always has been utter twaddle – simply an excuse for the Montreal Protocol and the assassination of useful chemical compounds.

Cuccinelli says EPA report supports his assertions
Virginia Attorney General Kenneth T. Cuccinelli II on Wednesday blasted the Environmental Protection Agency in the wake of a recent inspector general´s report that found it failed to follow federal rules in its process of using climate change data to conclude greenhouse gases are a threat to human health.

Map: The Climate Change Scare Machine — the perpetual self-feeding cycle of alarm
Two professors of sociology think they can explain why “Climate Deniers” are winning. But Riley E. Dunlap and Aaron M. McCright start from the wrong assumption and miss the bleeding obvious: the theory was wrong, the evidence has changed, and thousands of volunteers have exposed it.
The real question sociologists will be studying for years to come is: how was an exaggerated scare, based on so little evidence, poor reasoning and petty namecalling, kept alive for two whole decades? (Jo Nova)
The South Pacific’s water crisis
And not a drop to drink
ONE canary in the climate-change coalmine may have just quietly fallen from her perch. The tiny Pacific island nation of Tuvalu has declared a state of emergency after a fresh water shortage forced it to shutter its schools and hospitals and begin water rationing across the country. Observers blame the shortage on the changing weather patterns and rising sea levels associated with climate change—and warn they could be a sign of things to come for the whole region. (Economist)
What utter rubbish! Tide gauge data shows no particular trend for sea levels at Tuvalu but does register the state of the El Niño Southern Oscillation (ENSO).
Due to regional atmospheric pressure changes deforming the sea surface lens sea levels fall around Tuvalu during the warmer El Niño phase and rise during the earth-cooling La Niña phase.
We are currently entering what appears to be a second La Niña peak and sea levels have been above “normal” around Tuvalu for more than a year.
Moreover, La Niña phases cause a southerly shift in local wind and rainfall patterns, always leading to drought in the region.
Tuvalu suffers drought when earth is coolest and above-normal rainfall when earth is at its warmest during El Niño events. And so it has always been.
Response To A Question On Skeptical Science On The Fraction Of Positive Radiative Forcing From CO2

UP NIGS: Too much fuss about sea level rise….
…not enough attention to land subsidence
Caroline J. Howard
MANILA, Philippines – Filipinos cannot afford to use old practices like using deepwells, if the communities want to stay afloat.
While climate change, along with rainfall volume, may be to blame in part for flooding, some experts say factors including land subsidence or ground sinking resulting from excessive ground water extraction may be the bigger contributor to floods.
“There is so much fuss about sea level rise but not much attention to land subsidence. We have sea level rise due to global warming and it is rising at 2 millimeters per year. We’re so concerned about it but the land is subsiding at 5.5 centimeters per year,” said Dr. Mahar Lagmay of the UP National Institute of Geological Sciences on ANC’s “Headstart.”
Lagmay said excessive ground water extraction by industries and those involved in aqua culture have also contributed to the sinking of land. (ABS CBN)
At least, I assume they are hitching as there are no reports of north-bound magnolias towing U-haul trailers…
As the Climate Warms, Magnolias Move North
Scarlett O’Hara herself would likely be scandalized by what researchers found when scouring a plot of central North Carolina forest outside Chapel Hill. Jennifer Gruhn was looking for Southern magnolias, one of the most enduring symbols of the American South (besides Scarlett herself, of course), and the state flower of both Mississippi and Louisiana.
The scandal was that she found them — no fewer than 500 of the magnificent trees, with their dark green leaves and spectacularly fragrant blossoms — in an abundance unexpected for a location so far north. And as with so many changes in the natural world lately, Gruhn, a biology graduate student at Washington University in St. Louis, thinks climate change may be at least partly responsible.
Writing in the June issue of Southeastern Naturalist, Gruhn and her co-author Peter White, of the University of North Carolina, Chapel Hill, point to average temperatures some 2.7°F higher, and a growing season several weeks longer, than it was a few decades ago. (Climate Central)
Climate talks eye revenue from shipping
PANAMA CITY — With nations facing gaping shortfalls meeting pledges on climate change, several governments and activist groups are pushing to put a price on shipping emissions to fund aid to poor countries.
Commercial ships virtually always run on fossil fuels and produce nearly three percent of the world’s carbon emissions blamed for climate change — twice as much as Australia — but are unregulated under the Kyoto Protocol.
Analysis: South African carbon tax plan hurts job ambitions
South Africa’s carbon tax plan is running headlong into a clash with its job creation plans, putting the government in a bind ahead of hosting of a global climate summit at the end of the year as it seeks to rein in emissions without hurting growth.
Africa’s biggest economy wants to cut CO2 emissions by 34 percent over the next decade but has little flexibility to make fast changes with major employers among the top polluters and its cash-strapped power sector almost fully reliant on coal.
The government has said its top priority is to cut into a chronic 25 percent unemployment rate but industry will have less money for new employees if it is forced to pay high carbon taxes and while exports flounder due to an economic slump in Europe and the United States. (Reuters)
Carbon tax to cost $1 trillion: committee
October 7, 2011 – 12:14PM
The federal government’s carbon tax will cost every Australian $40,000 in the period to 2050 and a cost-benefit analysis should be conducted before it passes into law, an opposition-dominated Senate committee says.
The select committee on the scrutiny of new taxes on Friday tabled a 361-page report in parliament looking at whether a carbon tax should be brought in at a time of uncertainty about the global economy and whether there will be a concerted international effort to cut carbon emissions.
Labor’s laws to establish in a fixed $23-per-tonne carbon price from July 1, 2012, before moving to an emissions trading scheme in 2015, are set to pass the lower house next Wednesday before going to the Senate for debate.
The committee found that under the government’s own modelling the carbon tax would impose a $1 trillion cost on the Australian economy, or $40,000 per person.

EU Court: Airline Carbon Law Is Legal
DANIEL MICHAELS And ALESSANDRO TORELLO
BRUSSELS—A top European court backed the European Union’s plan to regulate airplane greenhouse emissions against strong international opposition, escalating a diplomatic row between the 27-country bloc and many of the world’s biggest powers.
The Court of Justice issued Thursday a preliminary opinion supporting an EU law forcing any airline landing at or departing from an European Union airport to hold permits to emit greenhouse gases.
Supporters say the law will start cutting carbon-dioxide emissions from air travel and prompt other countries to take similar actions. But critics say the EU has acted unilaterally, exerting authority beyond its boarders, and has created controversy that will delay global efforts. Industry officials say passengers may avoid traveling through the EU, where ticket prices will rise as a result of the plan, and instead travel through hubs elsewhere, such as in the Persian Gulf.

Keystone XL: The wrong question
The Keystone XL pipeline from Canada’s tar sands would have pros and cons, but foes would do better to shift their focus to the larger environmental issues.
The question of whether to build an oil pipeline from the tar sands of Alberta, Canada, to refineries in Texas is turning out to be one of the most important political decisions of the year for the Obama administration. It’s an agonizing choice because the costs and benefits of building it are so closely balanced; opponents have overstated the environmental risks, and proponents seem oblivious to the consequences of continuing to feed our nation’s oil addiction.
The Keystone XL pipeline would run 1,700 miles and cost $7 billion, generating thousands of construction jobs. It would increase oil imports from a stable, friendly neighbor while decreasing U.S. reliance on more volatile (and sometimes hostile) OPEC regimes. What’s more, pipelines are the safest way to transport oil. (LA Times)
