Global Warming will Wipe Out Plankton from Oceans

admin — Fri, 19 Mar 2010 07:53:52 +0000

Plankton is the most prevalent life and food source in the ocean. Phytoplankton, which carries on photosynthesis near the ocean surface, serves as food for the zooplankton and fish.
The microscopic plants that underpin all life in the oceans are likely to be destroyed by global warming. Scientists have discovered a way that the vital plankton of the oceans can be starved of nutrients as a result of the seas getting warmer. They believe the findings have catastrophic implications for the entire marine habitat, which ultimately relies on plankton at the base of the food chain.

Plankton are microscopic animals (zooplankton) and algae (phytoplankton) that live in the ocean. They drift on currents and provide food for many ocean residents.

“A larger temperature difference between two water layers implies less mixing of chemicals between these water layers,” he said. “Global warming of the surface layers of the oceans, owing to climate change, strengthens the stratification and thereby reduces the upward mixing of nutrients.”

Scientists had believed phytoplankton, which survives best at depths of about 100 metres, is largely stable and immune from the impact of global warming. “This model prediction was rather unexpected,” Professor Huisman said.

“Reduced stability of the plankton, caused by global warming of the oceans, may result in a decline of oceanic production and reduced sequestration of the greenhouse gas carbon dioxide into the oceans.”

Phytoplankton therefore acts as a carbon “sink” which takes carbon dioxide from the atmosphere and deposits the carbon in long-term stores that can remain undisturbed for thousands of years. If the growth of phytoplankton is interrupted by global warming, this ability to act as a buffer against global warming is also affected - leading to a much-feared positive feedback.

Any surfers like good waves but it is sometimes hard to catch the right one. Here are photos of beautiful waves and how-to to surf on waves the right way.

How to catch a wave? As you feel the wave lift you and your board, paddle as hard as you can and lean your weight forward. The natural tendency is to lean back to keep the nose from going under water, but that will only slow your momentum which in not conducive to wave-catching.

If we look into history, Pierre and Ernest Michaux, invented the first bicycle during the 1860s but there is evidence that the bicycle is older than that. The German Baron Karl Drais von Sauerbronn invented the “Laufmaschine” or “Running Machine”, a type of pre-bicycle. The steerable Laufmaschine was made entirely of wood and had no pedals.
Rider had to push feet against the ground to make the machine go forward. The following collection is much more modern and in some cases powered by fuel.

Active Solar Home Design

admin — Fri, 05 Feb 2010 12:59:15 +0000

Active solar systems collect and absorb solar radiation, then transfer the solar heat directly to the interior space or to a storage system for later usage. Exists two basic types of active solar systems. One liquid based and the second is air based. If the system cannot provide adequate space heating, back-up system provides the additional heat.

The cost of an active solar heating system will vary. Commercial systems range from $30 to $80 per square foot of collector area. Usually, the larger the system, the less it costs per unit of collector area. Commercially available collectors come with warranties of 10 years or more, and should easily last decades longer.
