As a forester the most frustrating thing I see is the competition that timber has from steel in the likes of new home framing. This is happening when steel – a finite, high-energy use, and unsustainable product – competes with wood, a completely sustainable low-energy use product. Clearly if steel manufacturing in the house framing market paid its true environmental cost, the choice to use sustainable environmentally-kind product would be a no-brainer.
Much of the debate around climate change is about how much the weather has changed. I believe, the weather changes in the last 10 or 20 years has little to do with climate change. Rather the real centre of the debate, is around what is anthropogenic (human induced) change.
Milutin Milanković (1879 – 1958) is credited with the theory that is now known as the Milanković cycles. He determined, via mathematical process, that matters like orbital variation and axial tilt played a major role in determining our climate.
To quote from wikipedia – “After his death, most of the scientific community came to dispute his “astronomical theory” and did not recognize the results of his research. But ten years after his death and fifty years from the first publication, Milanković’s theory was again taken under consideration. In the beginning, recognition came slowly.” But later the theory was proven to be accurate, as technologies gave us the ability to accurately map these “astronomical variations”.
