Climate change, the ozone hole, and skin cancer - they're all connected : Comments

By Noel Wauchope, published 30/12/2013

And there's skin cancer on the increase 2 common forms, and the less common melanoma, and another nasty rare one, that is becoming less rare in Australia.

To be fair Nutter, I probably only recall the figures on that sail, because I was really surprised at how much current assistance I had. It was not normally anything like that, more like 3 Knots.

A week or so earlier I had taken all day to cover the 30 odd nautical miles from Newcastle to Port Stephens, but had not streamed the log, so did not know.

The slow trip meant I arrived after dark, & with only a general chart, & never having been in there, I was not game to try entering. I spent the night sailing north about 2/3 miles off the entrance. With just the main up, & over sheeted, I had the boat going nowhere over the ground, but sailing at 3.5 Knots through the water of that current.

You have successfully confused day to day weather with decade to decade, or century to century, climate change.
Given that the events you refer to are close to a century old, when we did not have anywhere near the information gathering sources we have now, I doubt whether any explanation at all is possible.

All of this is on a blog lamenting a rise in skin cancers!
Is it possible we might return to that theme?

imajulianutter tells me that I am stupid to say that (anthropogenic) climate change is happening.
Yet in another post he or she asks me to explain the complexities of arctic ice in relation to global warming.
Presumably that was a rhetorical question, seeing that I am stupid, and thus unable to answer.
Here are juat a few of the (English language)scientific organisations that explain anthropogenic climate change, in its various aspects:

Australian Academy of Science
Australian Meteorological and Oceanographic Society
Climate Council
Commonwealth Scientific and Industrial Research Organisation
Bureau of Meteorology
CSIRO Marine and Atmospheric Research
Office of the Chief Scientist (Australia)
The Climate Institute
National Academy of Sciences (USA)
British Science Association
British Association for the Advancement of Science
Department of Energy & Climate Change - GOV.UK
Directorate-General for Climate Action (European Commission)
IPCC - Intergovernmental Panel on Climate Change

There are many others, and also in many other languages, from other nations.
My question to imajulianutter, and to those other "climate sceptic" commentators is this:
Do you think that all those thousands of scientists are part of a gigantic conspiracy, or are they all just stupid?

In the 1950s, 1960s and 1970s, Sun Protection Factor sun screens were unknown. I used to spend as much time as I could outside wearing shorts or Speedos. I regularly got sunburnt. I am now starting to pay the price for this.
I’ve had three cancers cut out, one on my left forearm and two in the left ear. I’ve had 8 – 10 frozen off with liquid nitrogen and I use Efudix cream regularly in late autumn, winter and early spring. Efudix [fluorouracil] is cyto-toxic: this means it kills cells specifically those which are dividing fastest i.e. cancer cells.
Edudix has a number of drawbacks: no more than 2% of the skin can be covered at any time e.g. the back of one hand and that forearm, it takes 3-4 weeks for a complete treatment, the treated parts turn a blotchy bright red and it is not on the PBS - $53 for a tube good for treatment of one area or 2% of the surface. The bright red bits are the keratoses and early cancers being killed. When I use Efudix on my face, I find that I am constantly explaining why I look such a sight, which doesn't stop me using it.
I have a full skin check by a competent specialist dermatologist each year. Up til now, I have not had a melanoma diagnosed.

I had hoped that this blog would focus on skin cancers, their treatments, how to avoid them and what might possibly be the risk factors leading to an increased rate of cancers and an increased rate of the real nasty melanoma.

If it’s OK by everyone who reads this blog, I would prefer to avoid discussion of global warming, for which there are other blogs where it is the centre point of discussion, and concentrate on skin cancers. Global warming is a side issue: the main issue is skin cancer, avoiding it, recognising it, treating it and surviving it.

To Brian of Buderim,and anyone else who's interested in skin cancer. Good idea to focus on this problem, which is immediate for Australians,but also a burning issue for today's children and their future. (but is this online journal a magnet for climate sceptics?)

Anyway - here is another idea on skin cancer:
Tea tree oil may be used in future as a fast, cheap, safe and effective treatment for non-melanoma skin cancers and precancerous lesions, according to researchers at The University of Western Australia.

A three-year study by UWA's Tea Tree Oil Research Group has found solid tumours grown under the skin in mice and treated with a tea tree oil formulation causes inhibition of tumour growth and tumour regression within a day of treatment.

Within three days, the tumours cannot be detected.

The study by research associates Dr Sara Greay and Dr Demelza Ireland of UWA's School of Biomedical, Biomolecular and Chemical Sciences and colleagues was published online in the journal Cancer Chemotherapy Pharmacology.
