“Green water policies are un-sustainable, even suicidal” …

The Greens have a severe aversion to dams. This is not based on science, but is pure unadulterated ideology.

Be Like the Beaver – Build More Dams

Be Like the Beaver – Build More Dams

Much of the water that falls on land is driven relentlessly back to the sea by the shortest possible route. Allowing this loss to happen is poor water management. The oceans are not short of water.
– Viv Forbes Continue reading Be Like the Beaver – Build More Dams

The beavers show how it’s done. So does Viv Forbes.

[…] People have long recognised the importance of conserving fresh water – early settlers built their homes near the best waterholes on the creek and every homestead and shed had its corrugated iron tanks. Graziers built dams and weirs to retain surface water for stock (and fence-crashing wildlife), used contour ripping and good pasture management to retain moisture in soils, and drilled bores to get underground water. And sensible rules have evolved to protect the water rights of down-stream residents.

Rainfall is often a boom and bust affair. Much fresh water is delivered to the land surface suddenly in cyclones, storms and rain depressions. But “The Wet” is always followed by “The Dry”, and droughts and floods are normal climatic events. People who fail to store some of the flood must put up with the drought.

Greens should learn from the beavers. Strings of dams can moderate flood risk, as well as creating drought sanctuaries and secure water for graziers, towns, irrigators and wildlife. Modern cities could not survive without large water storages for drinking water, sanitation, gardens and factories.

Fresh water is also necessary to produce fresh food. We can have fresh milk, butter, cheese, meat, vegetables, nuts and fruit; or we can irrigate the oceans and import fresh food from more sensible countries. And without fresh water and fresh food, there will be no local food processing.

Those infected with the green religion believe we should waste our fresh water by allowing it all to return as quickly as possible to the salty seas. They fight to protect beaver dams and natural lakes, but persistently oppose human dams and lakes. Some even want existing dams destroyed, while wasting billions on energy-hungry desalination and sewerage re-treated plants, pumps and pipelines.

They also want to prohibit man’s production of two drought-defying atmospheric gases, both released by the burning of hydrocarbons – carbon dioxide which makes plants more drought tolerant, and water vapour which feeds the clouds and the rain.

Green water policies are un-sustainable, even suicidal.

Humans must copy the beavers and “Build more Dams”. And help the biosphere by burning more hydrocarbons.

Update, We need to build dams to take advantage of this good news:

Hooray!  A study that comes to a logical conclusion about warming

Warming causes more rain!  Who woulda thunk it?  The journal article is “More extreme precipitation in the world’s dry and wet regions”.  The findings run counter to the usual Warmist claim that dry regions will get drier (John Ray)

The latest climate predictions show that both wet and dry places will experience more rainfall in the future

The study was carried out by Dr Markus Donat and his team at the University of New South Wales, Sydney.

Using a combination of observations and climate models, Dr Donat found that extreme daily precipitation over the last six decades shows ‘robust increases’ in both wet and dry areas.

He found that precipitation extremes have increased by about 1 to 2 per cent per decade since 1950, in both wet and dry regions, and there are ‘statistically significant’ trends towards wetter conditions for both total precipitation and extreme events.

Critically, the steady increases in rainfall were found to be directly related to the rise in global temperature.

With temperatures expected to rise further, according to climate models, this will mean more rainfall everywhere – including places that have historically been dry.

This surprise finding overturns what was previously expected.

When analysing local rainfall patterns, Dr Donat reports that ‘a wet-get-wetter, dry-get-drier pattern was not seen over most global land areas.’

Projections show the trend of increasing rainfall is expected to continue until at least the end of the 21st century.

The researchers said this is due to the increased moisture content the atmosphere can carry as it becomes warmer.

While increased rainfall in the world’s drought zones may be welcomed, the researchers say this may not lead to more water being available because it could evaporate quickly.

It might, though, lead to many more cases of flooding because these regions do not have the right infrastructure to cope with extreme rainfall.

The findings are published in the journal Nature Climate Change.
