Watts Up With That?

Guest post by Larry Fields

The last Ice Age razed all of the coniferous forests in Finland. After the ice sheet retreated, trees from elsewhere–like the Scots Pine–gradually colonized the vacant niches. On a smaller scale, the same thing happened in many high mountains of the Earth’s temperate regions, including the Sierra Nevada Range of California. We can learn a thing or two about climate history from Alpine dendrology.

Round Top Lake, at 9340 feet elevation in the Northern Sierra near Carson Pass, is my favorite place for informal climate history research. Whitebark Pine trees grow in tight clumps around the North half of the lake.

Other high altitude conifers–like Lodgepole Pine, Mountain Hemlock, and Red Fir–also grow in the Carson Pass area. But Whitebark Pines can grow at slightly high elevations than these other trees.

At Round Top Lake, the Whitebark Pines in any given group are nearly identical genetically, since they reproduce asexually. New tree trunks grow outward from an existing root system. This is called suckering. The seeds that do sprout can’t endure the harsh Winters at that altitude. Walking 100  yards downhill from the lake on the main trail, one can see Whitebark Pines that have grown in a more normal way.

Naturalist Jeffrey P. Schaffer mentioned Round Top Lake in the 1989 edition of his book, The Tahoe Sierra: A Natural History Guide to the 106 Hikes in the Northern Sierra. Here’s a link to a review of a more recent book by Schaffer.

We’ve made so much progress in the USA. 75 years ago, we may have witnessed some scenes like this in today’s China. Unfortunately, the de-industrialization of the west just moved the western problems of the past to a country that doesn’t seem to care much about pollution control.

At the junction of Ningxia province and Inner Mongolia province, I saw a tall chimney puffing out golden smoke covering the blue sky, large tracts of the grassland have become industrial waste dumps; unbearable foul smell made people want to cough; Surging industrial sewage flowed into the Yellow River…”

Global warming skeptic tells group that cure is worse than problem.

By Lee Roop, special to The Huntsville Times

Dr. John Christy

HUNTSVILLE, AL – Science doesn’t support current global warming alarms and, even if it did, current proposals to fix things won’t work and might make life worse.

That’s the well-known view of Dr. John Christy, a University of Alabama in Huntsville climate scientist, and Christy spelled out the “whys” and “why nots” of his perspective Tuesday to the Huntsville Rotary Club.

“Consensus is not science,” Christy began, quoting the late author Michael Crichton.
Christy, the state climatologist, is well-known in the global warming debate. He has testified before Congress many times and was an unpaid expert witness for the automobile industry in a federal lawsuit against fleet mileage requirements.

Here’s Christy’s basic argument: Read the rest of this entry »
