Time for arguing against the enormity of climate change impacts on our earth are behind us. There is absolute certainty that our profligate use of energy is really harming our world.

Arguments to reduce actions designed to reduce carbon dioxide emissions are fallacious.

In our country, that is experiencing reduced rain and longer more frequent heat waves, and in particular, reduced snow fall in our hydro areas, it is ridiculous to see new hydro as some miraculous solution.

Dear Tony,

<<There is absolute certainty that our profligate use of energy is really harming our world.>>

Please speak for your own world, not "our" - the world that I know cannot be harmed!

I think Aiden that you had better read this.

Prieto and Hall conclude that the EROI of solar photovoltaic is only
2.45, very low despite Spain’s ideal sunny climate. Germany’s EROI is
probably 20 to 33% less (1.6 to 2), due to less sunlight and less
efficient rooftop installations.

These two researches are probably, from what I have previously read,are
at the top of the scale in their field.

I must admit to being surprised at how low the ERoEI is for solar.
It certainly means the the RET really is a bomb.
The PVs that you referred to a while back with a magnitude increase in
output really would be a saver. Trouble is it might be like fusion;
Always 50 years away.

To Yuyutsu,
War in Syria and general uprisings in Egypt probably initiated by climate change. Huge fires and heatwaves in Russia, Ukraine, US and floods in Australia dramatically reduced Egypt's ability to import necessary flour for their staple diet. Of course the Egyptian population rebelled.

Mass migration from drought ridden Euphrates valley in Syria sent almost 1 million subsistence farmers to cities, where government gave no support - started uprising.

Massive floods in Pakistan a few years ago.

Statistics showing marked increase in death rates among the elderly during heat waves.

Your world obviously does not include such locations. Your world is devoid of scientists.

But, the tide is definitely turning against those who deny the science. Even the youth in the US are starting to use the law to charge governments for not protecting their environment, for polluting a common good - our atmosphere.

You can turn your blind eye to obvious climate related problems - but don't worry - others are working to safeguard your part of our world as well.

Dear Tony,

You did not relate to my statement: the world cannot be harmed even if all humans died.

Instead, you mention this silly and tired hoax of "climate change": Margaret Thatcher is dead and my brother is still waiting for the sea-level to rise by 61 metres so he gets a private beach, as promised by those clowns. If you like to speak about the environment, go ahead as there are indeed serious issues there for those who care about the continuation of the human race, but mentioning such nonsense in their place does not add to the credibility of your arguments.

Tony 123, sorry to prick one part of your bubble.
The problem with Egypt has nothing to do with climate change.
From when Egypt became an oil exporter the government has subsidised
food and fuel. This enabled the population to rise from around
40 million, which was the population that the Nile could support to
85 million today.

However their oil production peaked in 2000 and has been declining
since then. As it declined the government had to reduce the subsidies
and this caused the riots over food and fuel which caused Mubarik's downfall.
Somehow they have to get rid of 45 million people !
