Floating Islands

Dear Readers ,Found this while searching the net and thought of sharing with you all.Enjoy.

Floating Islands Guest Post by Willis Eschenbach Much has been written of late regarding the impending projected demise of the world’s coral atoll islands due to CO2-caused sea level rise. Micronesia is suing the Czech Government over CO2 emissions that they claim are damaging their coral atolls via sea level rise. Tuvalu and the Maldives are also repeating their claims of damage from CO2. If the sea level rises much, they say they will simply be swept away. Rece … Read More

Plants also Hibernate

Contrary to general perception plants also hibernate.The “winter sleep” of trees, shrubs and many other plants is seen on every hand during winter. With the approach of Fall, these shed their leaves, their sap descends and they exist in a dormant state until the coming of Spring. In like manner bulbs, tubers, etc., undergo a prolonged “winter sleep.” These plants fast through the whole of the winter months, taking no food during the time. They take no carbon and nitrogen from the air and extract no minerals and nitrates from the soil. Metabolism is practically non-existent during this period. The cessation of the flow of sap in trees during the winter season is similar to the almost ceasing of circulation in hibernating animals. Plants like the daffodil, onion, beet, turnip, etc., store up large supplies of food in their roots–bulbs and tubers–during the Summer. Their tops die off in the late Fall or early Winter and they lie dormant during the long Winter, only to send up new stems and leaves when Spring arrives. This storing up of food in their roots is similar to the storing of fat by the bear.

Ice Floes in Oceans

Ice floes are frozen masses of seawater (saltwater) that float on the surface of the sea. The term is applied to any relatively flat piece of sea ice that is free moving – unlike pack ice.

The tracking of ice floes is important to both understanding critical environmental issues such as global warming, and to aid in Arctic navigation.

Floes can be quite small or extremely large, and are termed according to horizontal size as follows:
•  Giant: Over 10 km / 6 miles across.
•  Vast: 2-10 km / 1½-6 miles across.
•  Big: 500-2000 meters / 1640-6500 feet across.
•  Medium: 100-500 meters / 330-1640 feet across.
•  Small: 20 -100m / 65-330 feet across.

The ice forms outward from the land during winter, and each spring, Arctic hunters like to venture out onto the ice. The ice or floe edge – where the ice meets open water – is the best location for hunting and fishing.

It is also the most dynamic and dangerous place to be in the spring, and each year, unsuspecting people are set adrift as the ice fractures and large ice floes float out to sea. This often happens in weather conditions that make air searches and rescue efforts difficult or impossible.

Synthetic Life and Ethics

Dear readers,this is a post from from Onionesque Reality.

Synthetic Life and Ethics I am late with my echo statement on this. Over the past few days, the internet is abuzz with news of Craig Venter and his team for creating the first fully functional cell, controlled by synthetic DNA and discussions on what might be the ethical consequences of future work in this area. The fact that this has happened is not surprising at all. Dr Venter has been very open about his work and has been promoting it for some years now.  For instance, … Read More
