Paul Crutzen – Heroes of the Environment – TIME
We would be wise to heed Crutzen on global warming, too, because he can fairly be described as the chief scientific caretaker of life on the planet. He suggested the potential climatic danger of nuclear war, a threat later popularized as “nuclear winter” by Carl Sagan. He has made major contributions to our understanding of acid rain and the effect of aircraft on the atmosphere. He has not flinched from speaking out even when it annoys industry or governments, and he does not hide his concern for the lack of U.S. leadership in addressing global warming. In contrast to the prompt attention paid to the ozone threat, foot-dragging on climate change has convinced Crutzen that major geo-engineering may be needed to cool the planet. He suggests a massive injection of sulfur into the stratosphere to form particles that reflect sunlight away. It’s a radical proposal that just might jolt some politicians into realizing what researchers learned long ago: that this scientists’ scientist always seems to be one step ahead of everybody else.

Not related. I just found out that stringsbymail.com allows you to buy bass sets and treble sets instead of the whole set so you would be able to get 3 Treble and then three bass stings with out any left over. They let you mix the style of strings as well EJ 45c and Titianiums.
