Green Options

So-called “dead zones”–patches of ocean lacking aerobic (oxygen breathing) life–will most likely increase due to a rise in carbon dioxide (CO2) concentrations.

Because of CO2 build up in the atmosphere, its level of concentration in the oceans also increases. There, some of the CO2 converts to a simple acid called carbonic acid. (H2CO3).

What is becoming a much-studied phenomenon in recent years, these dead zones of depleted oxygen (02) - typically found at depths between 300 and 600 meters–are the result of several factors working separately and in combination: lower sea surface 02 levels, less heat exchanging (”ventilation”) with mid-level ocean depths due to over-all warming, and “euthrophication events” (an over-growth of a species due to excess nutrients).

Let’s talk climate further. That will provide insight for add-ons necessary to achieve year-round comfort.

Yurts appear logical for my tropical climate where elements of nature aren’t so severe. Well, surprise, but no worry. Just know that maintaining yurt warmth can be an easier task than keeping cool.

This is a yurt living series that was recently launched with a focus on purpose. My topic is climate now, which is not a hindrance for yurt lovers at all. However, consideration of comfort causes a need to review add-ons and upgrades.

Opening windows is the easiest way to reduce formaldehyde concentrations in homes. The best option is to use only building products that emit little or no formaldehyde. However, when conventional building materials are already in place and emitting formaldehyde, the problem will remedy itself with time. Materials that are several years old emit far less formaldehyde than new products.

Big buildings save energy by controlling which areas need to have heating or cooling, and not wasting energy on those spaces when they are not occupied. Similar features are sometimes found on high end homes (and are probably almost a necessity on the oversized starter castles spread across the outskirts of every city). But systems like that are hard to retrofit into smaller, older homes.
