New techniques mean that wood can now be used for much taller buildings - "Wood has many attractions as a construction material, apart from its aesthetic qualities. A wooden building is about a quarter of the weight of an equivalent reinforced-concrete structure, which means foundations can be smaller. Timber is a sustainable material and a natural 'sink' for CO2... Using wood could reduce their carbon footprint by 60-75%, according to some studies. There are two main concerns about using wood to build high. The first is whether wood is strong enough... the second worry: fire."
We've talked about wood identification before (previously), but there's so much more than The Wood Database, starting with Identification Of Common North American Woods. [more inside]

"My subject is a barren one – the world of nature, or in other words life; and that subject in its least elevated department, and employing either rustic terms or foreign, nay barbarian words that actually have to be introduced with an apology. Moreover, the path is not a beaten highway of authorship, nor one in which the mind is eager to range: there is not one of us who has made the same venture, nor yet one Roman who has tackled single-handed all departments of the subject."Naturalis Historia was written by Pliny the Elder between 77 and 79 CE and was meant to serve as a kind of proto-encyclopedia discussing all of the ancient knowledge available to him, covered in enough depth and breadth to make it by a reasonable margin the largest work to survive to the modern day from the Roman era. The work includes discussions on astronomy, meteorology, geography, mineralogy, zoology and botany organized along Aristotelian divisions of nature but also includes essays on human inventions and institutions. It is dedicated to the Emperor Titus in its epistle to the Emperor Vespasian, a close friend of Pliny who relied on his extensive knowledge, and its unusually careful citations of sources as well as its index makes it a precursor to modern scholarly works. It was Pliny's last work, as well as sadly his sole surviving one, and was published not long before his death attempting to save a friend from the eruption of Mt. Vesuvius that destroyed Pompeii and Herculaneum, famously recounted by Pliny's eponymous nephew Pliny the Younger.

Romeyn Hough's American Woods is one of the most astonishing books of the late 19th century, a 14-volume set containing a thorough survey of the trees of the U.S., complete with thinly sliced samples of the wood of each tree. Complete sets of this mammoth undertaking are today rare and highly prized.

Grow your own. Furniture that is. Christopher Cattle has pictures and basic instructions on growing a three legged stool. Similiar previously here, here, and here.
Obviously, the answer to global warming is to cut down all the trees. Or maybe we should just paint them all white?
