Jane C. S. Long, associate director-at-large of the Lawrence Livermore National Laboratory in California, is convinced that the only sensible way to combat climate change is to work toward “a zero-emission energy system as fast as possible.” But as chairwoman of the Bipartisan Policy Center’s 18-member task force on geoengineering, the hydrologist and energy expert realized two fundamental things: that the world has still not come to its senses on global warming, and that science would be remiss if it didn’t consider the possibility that CO2 emissions will continue to soar for decades.Because educational institutions are controlled by the One Percent, I suppose one ought to forgive US scientists for not understanding that the social-economic system which is dedicated to securing profits and power for the One Percent is the source of the problem, and needs to be changed. In any case, it appears that US scientists are left with dreaming up desperate fantasies for engineering the Earth's climate.
Another explanation might be that they are too intimidated by threats coming from the One Percent to consider social-economic system change. See this piece entitled, "Attacks paid for by big business are 'driving science into a dark era'". Activists for the 99 Percent are very familiar with the extreme and often brutal methods that enforcers of the One Percent are willing to use to protect their system.
