kaskawulsh Glacier Stops Flowing into Slims River

 ▶The river Slims stops as a Glacier called Kaskawulsh changes direction of river water. kaskawulsh it Glacier to flowing on arctic Glacier kaskawulsh ◀ |
Most accept that global warming as scientifically proven, though some still will not accede. The north pole is getting smaller as glaciers melt due to higher temperatures. This can seen "on the ground" and from space.  ||| north arctic Stops at flowing in Glacier up kaskawulsh |
Kaskawulsh Glacier Slims River
Canada's Slims River in Yukon did receive inflow from the Kaskawulsh glacier. The weather got a lot hotter in 2016. This increased the melting rate of glaciers.  The flow has stopped because a deep opening formed in the glacier: dust storms sweep along the dry river bed that used to go north. It happened in four days. The glacier now feeds west into the Alsek River that turns south.

Researchers got a shock when they visited the area recently. They hadn't been there since 2013. Just before the river stopped flowing, the temperature increased - 4.3 degrees Centigrade higher than normal. Rivers and lakes downstream of Slims have been detrimentally affected. The ecosystem of the Alsek River has also changed because there is more water flowing. |.| not. |.|       vel news to   | ambitious up.

Australia's Coast Will Be Lost

Australia could return to what it was millions of years ago - a cluster of islands covering a gigantic area.  The continent is very flat.  Mountains only occur on the east coast.  With rising sea level, first to go will be the large cities on the coast.  These are the major population centers.

After this, an inland sea will form.  There is no doubt that the Poles are melting.  This water has to go somewhere.  The population will fall by 80 per cent.  Even if many flee inland, there are no water and food resources there to feed everyone, unless of course Aboriginal culture still remains.  Most Aboriginals today are urbanized and have lost much of the their culture.

This will not be a solely Australian problem.  Most major cities in the world are on the coast, growing from estuaries where a large river flows into the sea. 

On the Gold Coast, high rise building are only meters from an unpredictable sea.  After storms, councils are called upon to repair the damage with money they don't have.  In a short time these buildings will have to be abandoned as councils condemn them as being too dangerous to live in.

There is no immediate worry because the rise in ocean level will  be steady.  This will give people time to move out.  There will be great financial loss to the nation though.  Natural disasters just consume GDP.  Nothing is produced from them.  In fact resources are drawn away from productive projects.

Surely Australia Could Pay a Little More for a Cleaner Planet

It is so strange how support for Kevin Rudd's Emissions Trading Scheme has totally evaporated. Kevin Rudd rightly claims that his backing down from trying to pass the legislation cost him leadership of his party and the country, so great was public support for it then. Times have changed. With big rises in water charges and electricity charges across the country people just don't want a bar of it anymore.

The proof of global warming is considerable. Ice is disappearing from the North and South Poles. Those who still contend that it is made up just to get money out of the public must be living on another planet - in their minds at least. No one wants to be paying higher prices for essential items than consumers in other countries, but the world is changing. China is making major changes. to reduce pollution. Finland introduced the world's first carbon tax in 1990. That is two decades ago. Sweden followed in 1991. Great Britain brought in a climate change levy in 2001. Boulder in Colorado has had a carbon tax on electricity since 2007. There has been a tax on all fuels in Quebec from 2007. British Columbia initiated the most efficient carbon tax in 2008 with $10 tax per metric ton rising to $30 in 2012. So Australians would not be alone in paying higher prices.

Young Australian families today have never known hard times. Economies go in boom and bust cycles. Australia has been lucky in avoiding the busts due to a small population "owning" a tremendous resources base. It is the only country in the world with this economic advantage. Surely Australia can do it a little tougher and help show the way to a better world.

Survey Vehicle Reaches Mercury

A NASA space vehicle, New Messenger, has reached Mercury and is beaming back information to CSIRO's Canberra Deep Space Communication Complex. It has taken nearly seven years to get to the hot inner planet. A Mercury day is six Earth months long while its year is only 88 days.

There is no possibility of humans landing on this little planet as the temperature reaches 430 degrees. Its minimum is extreme as well, minus 180 degrees. The sun would look three times bigger than on Earth if you could stand on it surface and look at it that is.

An earlier exploratory vehicle, Marina 10, only gave a cursory look at the innermost planet. The whole planet is to be mapped this time. It will show whether there is ice at the poles. The sun never shines into pole craters. A mystery to be solved is why Mercury is composed mainly of metals.
