Origins of Oceans

A thoughtful look st where all this water came from.



Sea levels could rise 10 inches from melting small glaciers.

A new riview of glacier research data paints a picture of a future planet with much less ice and a lot more water. Glaciers around the world are projected to lose anywhere from 18% to 36% of their mass by 2100, resulting in almost 10 inches of sea level rise.


This review is the best global comparison of glacier simulations ever put together. The lead author Regine Hock, from the University of Alaska, there is a clear messge that the glaciers are melting all over the world.

Over 200 computer similations say the same thing, substantial mass loss.

The overall study used more than 25 climate models with differing green house gas concentrations and atmospheric conditions. At present , the planet is moving toward the higher estimates of green house gas concentrations.

The study did not include the ice sheets of Greenland and Antarctica who behave different than mountain and land based glaciers.

Results indicate that smaller glaciers could play a biiger role in sea level rise than previuoslt thought. Globally, an almost 10 inches rise in sealevel by 2100 will be from smaller glaciers. An enormous impact.

Water levels dropping along the Ottawa River

For the first time in more than a week , water levels along the Ottawa River are falling instead of rising.

The decline in water levels is seen from Pembroke to Hawkesbury. Water levels are expected to continue to drop, but much remains dependant of the rain situation.


So things are headed in the right direction, but the flood will still be with us for awhile yet.

We are losing the great free flowing rivers

Only a third of the world’s great rivers  remain free flowing. The impact of dams radically reduces the benefits of healthy riv3rs. We all suffer.

Billions of people around the world rely on the rivers for water , food, and irrigation. Most large rivers today are fragmented and degraded. Untouched rivers are in remote areas like the Arctic and Amazonia. A quarter of long rivers thst once flowed freely to the sea still had such a course.

In Britain 97% of the nation’s river network has been interrupted by human built structures.

Thriving wildlife in rivers is crucial in keeping water clean, but freshwater habitats were found to be the hardest hit of all the ecosystems. Wildlife populations have tailed off by an average of 83% since 1970.Some 12m tonnes of fish are caught from rivers feeding millions.


Population growth makes it difficult to balance the demand for water, food, and energy, with keeping a healthy river.

Boil Water Advisory..What is it?

In January after 6 weeks the boil water notice was lifted in Prince Rupert BC, but Churchill, Manitoba was put under a boil water advisory.

Prince Rupert, a city of over 12,000 had high levels of parasites in their drinking water. High levels of cryptosporidium and giardia were detected….

The town of Churchill was under a boil water advisory due to poorly treated water entering the towns water system.

Carman , Manitoba was also under a boil water advisory…

What is a boil water advisory?

Peak forecasts for the Ottawa River still rising.

Looks like the spring flood of 2019 will still be with us for awhile yet.

Water levels continue to rise with the rain from Thursday and Friday. At some points along the watershed 50mm of rain will have fallen. There is currently a state of emergency in Pembroke with the upper reaches of the Ottawa River reaching historic levels.


The Liquid Rainbow of Columbia

One of Mother Nature’s amazing glories is the Cano Cristales River in Columbia. The 62 mile long river  in the Serrania de la Macarena National Park is known as “the river of five colors” or the “liquid rainbow”.

The river bed has bright red, yellow, green, blue, and black colors for a few months when the conditions are right. The colors are produced during the reproductive process of the aquatic plants in the river a species of riverweed called Podostemaceae.

During the wet season the river runs fast and high, sun does not hit the river plants. During the dry there is not enough water. They are at their brightest during June and November.

This phenomenon happens nowhere else in the world. The area itself is a biodiversity hot spot where the Andes, the Amazon , and the Orinoco basins converge.

Monster Cyclone Fani

It is midday on Friday, as I write this Cyclone Fani is launching itself on the east coast of India. This is equal to a Cat. 4 hurricane hitting a low coastal area, including one of the world’s most vulnerable to storm surge areas Bangladesh.

The Bay of Bengal funnels and concentrates the storm surge towards the north end.

More than 100 million people are in it’s path. Massive evacuation efforts are underway…we will see in the coming days the results. Some of the deadliest cyclones to have hit have struck along the Bay of Bengal. A densely populated, low lying area, flimsy infrastructure.

Inland flooding is also expected from widespread rainfall. 3-6 inches of rain and more will be found.
